Recording material supply system, circuit board, structure, and ink cartridge for recording material consumption device

[0001] The present invention relates to an ink cartridge for an ink supply system and a printer.

Background Art [0002] The construction of the printers provides for the possibility of detachably installing ink cartridges or ink containers. These types of ink cartridges or ink cartridges usually contain different types of devices installed. An example of such a device is memory for storing information about the ink. There are also high-voltage circuits (for example, piezoelectric components used as residual ink level sensors) that emit a response signal in response to a voltage higher than the supply voltage of this type of memory. These types of devices are electrically connected to the printer driver (or external device). For example, in some cases the device and controller are electrically connected via contact connectors.

[0003] EP 1800872 discloses a printing material container that can be detachably connected to a printing device equipped with a plurality of connectors on the device side, a printing material container comprising a first device, a second device and a group of connectors containing a series of first connectors, at least one second connector and at least one third of the connector. The first series of connectors are connected to the first device and accordingly include the first contact forming the contact connection with the respective connector from among the series of connectors on the device side. At least one second connector is connected to the second device and includes a second contact forming a contact connection with the respective connector from among a series of connectors after

VP / 2126 / AW

3162 316 656Β1 device side. At least one third connector is used to detect short circuits between at least one second connector and at least one third connector and includes a third contact forming a contact connection with the corresponding connector from a series of connectors on the device side. At least one second contact, a series of first contacts, and at least one third contact are arranged to form one or several rows, and at least one second contact is located on the edge of one row or one of several rows.

Summary [0004] However, when using electrical connections based on this type of contact connection, many problems can arise due to incorrect electrical connection, incorrect connection or other connection problems. For example, there are situations where a power outage from the printer to a device such as memory leads to memory failure or corruption.

[0005] Such problems not only occur in situations where the device is memory, but are also often encountered in situations where other devices are used. These problems also occur not only with inkjet printers, but are often found in devices that use other types of printers (such as toner).

[0006] It would be beneficial to provide technology that reduces the likelihood of problems encountered when using contact-based electrical connections that connect to the connectors located on the print media consuming device.

[0007] One aspect of the present invention is the ink cartridge according to claim 1. [0008] In this configuration, the two contacts located on the second connectors that are used to detect the presence of the cartridge are located in the first line, with the power connector contact between them. which ensures that the electrical connection of the power connector works correctly when the cartridge is confirmed. This reduces the likelihood of incorrect connection of the power connector, which in turn reduces the likelihood of problems that could occur if a connector-based electrical connection is used.

[0009] Also with respect to this arrangement, since the likelihood of incorrect connection of the data connector or other similar connectors is smaller, the likelihood of problems that would occur if a connector-based electrical connection is used also decreases. In addition, because the electrical contact element that corresponds to the power connector is protected from accidental contact with a connector on a line other than the first line, the probability of problems that would occur if a connector-based electrical connection is used is reduced. [0010] The contacts of the two second connectors are preferably located at opposite ends of the first line.

[0011] With respect to this arrangement, since the contacts of the second connectors are arranged at opposite ends of the first line, the probability of detecting an error regarding the presence of

ΡΖ / 2126 / ΜΝ

316 2 316 656 Β1 cartridge in the print media consuming device is reduced.

[0012] Preferably, the memory operates after receiving a reset signal at a level other than ground potential, the first series of connectors include a reset connector receiving the reset signal, and the reset connector is located on a line other than the first line.

[0013] In this configuration, the likelihood of an operational error in the memory module is less.

[0014] The ink cartridge preferably also includes a side wall and a bottom wall, the side wall has a series of connectors, and the connector for supplying the printing substance is located on the bottom wall at a location not being the center of the side wall, the direction of assembly of the ink supply system to the device consuming the printing substance follows the direction of gravity.

[0015] In this configuration, the probability of incorrect connection in a series of connectors is reduced, which means that the likelihood of problems that would occur if a connector-based electrical connection is used is less likely.

[0016] In a preferred embodiment, the total number of contacts on the first line exceeds the total number of contacts on any of the series of other lines.

[0017] In this configuration, the likelihood that the electrical contact element of the print media consuming device will accidentally contact the wrong connector is reduced.

[0018] It is possible that the present invention will be used in a number of different practical solutions, for example in an ink supply system or printer.

A1. Device configuration:

[0021] FIG. 1 is an illustration depicting a printer as an embodiment of the present invention. This printer is one example of a device that consumes a printing substance. The print consuming device consumes the print substance in the printing process. The 1000 printer is equipped with a fine scanning feed mechanism, a main scan feed mechanism and a head drive mechanism. The fine scanning feed mechanism includes a paper feed motor (invisible) and a paper feed roller 10 which is driven by the paper feed motor. The fine scan feed mechanism is designed to move the sheet of printing paper P in the direction of fine scan using the paper feed roller 10. The main scan feed mechanism is designed to use the energy supplied by the carriage engine 2 to reciprocate in the direction of the main scan using a carriage 3 connected to the drive belt

1. The carriage 3 includes a handle 4 and a printhead 5. The drive mechanism of the printhead is intended to move the printhead 5 and shoot ink from it. The blown ink forms P drops on printing paper. The printer 1000 is also equipped with a main control circuit 40 that allows control of the mechanisms described above. The main control circuit 40 is connected to the carriage 3 via a flexible hose 37.

[0022] The handle 4 has been designed to connect a range of ink cartridges, described later, and is located on the upper side of the print head 5. Under normal operating conditions of the printer 1000 (printing), the ink cartridges are mounted in the handle 4 to provide the printer 1000 with cartridges. In the example shown in FIG. 1 you can mount six ink cartridges in the holder 4. For example, you can install one cartridge of each of the six colors: black, cyan, magenta, yellow, light cyan and light magenta. In addition, there are ink supply nozzles 6 on the upper side of the printhead 5 that feed ink from the ink cartridges to the printhead 5. In FIG. 1 shows a single ink cartridge 100 mounted in holder 4.

[0023] FIG. 2 and 3 are illustrations showing the electrical configuration of the printer 1000 and the ink cartridge 100. The illustration in FIG. 2 shows the entirety of the main control circuit 40, the carriage circuit 500 and the ink cartridge 100. FIG. 3 illustrates a configuration relating to a single ink cartridge 100 that represents a series of ink cartridges. This electrical configuration also applies to other ink cartridges.

The main control circuit 40 and the carriage circuit 500 are control circuits that are located inside the printer 1000 and are used to control the individual mechanisms of the printer 1000 to carry out the printing process; here these two circuits will be collectively called the 1000 printer control unit. Since the control assembly can be considered a separate device from the device attached to the ink cartridge 100, in some cases when describing the operation of the control assembly and the device, it will be called an external device of the device.

[0024] As shown in FIG. 2, carriage circumference 500 and ink cartridge 100 are connected by a series of paths. These paths include the LR1 reset signal line, LD1 data signal line, LC1 clock signal line, LCV power line, LCS ground line, first LDSN sensor control signal line and second LDSP sensor signal control line. These five types of lines; LR1, LD1, LC1, LCV, LCS branches and combines with all 100 ink cartridges (i.e. forming a bus). LDSN and LDSP sensor control signal lines are routed separately to each of the 100 ink cartridges.

[0025] As shown in FIG. 3, the ink cartridge 100 is equipped with a circuit board 200 and sensor 104. The circuit board 200 is equipped with a semiconductor memory module 203 (hereinafter referred to as "memory module 203") and seven connectors 210 to 270. The circuit board 200 serves as an element connecting, which in combination with connectors creates an electrical connection with the 1000 printer control unit. The circuit board 200 is designed to provide electrical connections between the printer control unit 1000 and the device (s) and the sensor (s) attached to the ink cartridge 100. Power connector 220, reset connector 260, clock connector 270, data connector 240 and ground connector 230 are designed to provide electrical connection to the Pvdd power supply contact field (hereinafter referred to as the power supply field), and the Prst reset contact field (hereinafter referred to as the reset field) , Psck clock signal contact field (hereinafter referred to as clock signal field), Psda data contact field (hereinafter referred to as data field) and Pvss earth contact field (hereinafter referred to as ground field), which is equipped with memory module 203. Various types of memory can be installed in memory module 203. The present embodiment uses memory designed so that it is possible to choose which memory cells will be available (read and write operations) within word units based on addresses generated according to the internal clock signal of memory module 203 (e.g. EEPROM or memory using a ferroelectric matrix memory cells). Memory module 203 stores information regarding the ink accumulated in the ink cartridge 100. As a memory module 203, you can use any device that has at least memory that can store data (or information), and in addition to this type of memory, it can be equipped with a CPU or similar device that increases its functionality. Such a device could for example contain a CPU and a part where the program would be saved.

[0026] The sensor 104 is used to detect the ink level. In the present embodiment, the role of the sensor 104 is performed by a piezoelectric element consisting of a piezoelectric body sandwiched between two electrodes. Piezoelectric element (sensor

VP / 2126 / AW

ΕΡ 2 316 656 Β1

104) is attached to the housing of the ink cartridge 100. After the control voltage is applied to the piezoelectric element, it undergoes deformation. This phenomenon is called the inverse piezoelectric phenomenon. The inverse piezoelectric effect can be used to force the piezoelectric element to oscillate. The oscillation of the piezoelectric element may persist even after the control voltage is disconnected. The residual oscillation frequency reflects the natural frequency of the surrounding body that oscillates with the piezoelectric element (e.g., ink cartridge housing 100 and ink). The residual oscillation frequency varies depending on the ink level in the ink cartridge 100 (i.e., whether the ink is still in the ink supply channel near the sensor 104). According to this principle, based on the residual oscillation frequency, you can determine if the remaining ink level is above or below a certain recommended level. The residual oscillation frequency can be read by measuring the oscillation frequency of the voltage generated by the piezoelectric element. The first sensor connector 210 and the second sensor connector 250 are electrically connected to both sensor electrodes 104 (piezoelectric element) respectively. The residual oscillation amplitude also varies depending on the level of residual ink. According to this principle, based on the variable voltage amplitude generated by the piezoelectric effect, you can determine if the remaining ink level is above or below a certain recommended level.

[0027] Printer 1000 also includes a contact mechanism 400 and a carriage circumference 500. A contact mechanism 400 and a carriage circumference 500 are located on carriage 3 (FIG. 1). The carriage circuit 500 is located on the control board located on the carriage 3. The control board is electrically connected to the main control circuit 40 via a flexible hose 37.

[0028] The carriage circuit 500 is equipped with a memory control circuit 501, a sensor 503 generating pulse control circuit and seven connectors 510 to 570. Power connector 520, reset connector 560, clock connector 570, data connector 540 and earth connector 530 are electrically connected with memory control circuit 501. Ground connector 530 is grounded (i.e. connected to printer ground 1000) via memory control circuit 501 and main control circuit 40. Connectors 520, 530, 540, 560 and 570 are connected to 100 connectors 220, 230, 240, 260 and 270 located on the ink cartridge via contact mechanism 400 (contact elements 420, 430, 440, 460, 470). That is, when the user installs the circuit board 200 in the printer 1000, the printer 1000 will be electrically connected to the connectors on the printed circuit board 200. Contact element 420 corresponds to the portion of the LCV power line shown in FIG. 2; contact element 460 corresponds to a portion of the LR1 reset signal line; contact element 470 corresponds to part of the LC1 clock signal line; contact element 440 corresponds to a portion of the LD1 data signal line, and contact element 430 corresponds to a portion of the LCS ground line.

[0029] Using these connectors, the memory control circuit 501 controls the memory module 203 and reads and writes data to and from the memory module 203. More specifically, the memory control circuit 501 supplies the VDD supply potential (supply voltage) to memory module 203 via power connector 520. The RST reset signal is sent from the memory control circuit 501 to the module

ΡΖ12Ϊ2 &amp; ΙΜΙ

ΕΡ 2 316 656 Β1 memory 203 via reset connector 560. SCK clock signal is sent from memory control circuit 501 to memory module 203 via clock connector 570. Data connector 540 is used to send (send and receive) SDA data signals between memory control circuit 501 and a 203 memory module. The VSS ground potential is sent from the memory 501 control circuit to memory module 203 via the 530 ground connector (the ground connector 230 located on the ink cartridge 100 has been designed to be permanently connected to the printer ground 1000 if the ink cartridge 100 is mounted correctly (i.e., it adheres tightly) inside the printer 1000 (more precisely in the handle 4)). The VDD supply voltage differs from the grounding potential (Grounding) of the 1000 printer.

[0030] In the present embodiment, the memory modules 203 of the ink cartridge 100 are initially assigned different ID numbers (identification numbers). These ID numbers are identification numbers that allow the memory control circuit 501 to recognize the 203 memory modules connected via buses. The memory control circuit 501 sends data representing the ID number of the memory module 203 to execute the command to the LD1 data signal line, and then sends the data constituting the command itself. The memory module 203 with the given ID number then performs the operation indicated in the command (for example, reading or writing data). 203 memory modules whose ID numbers differ from the selected ID number do not respond to the command, but instead wait until their own ID number is called (this issue will be discussed in more detail later).

[0031] In the present embodiment, the memory control circuit 501 and the memory module 203 are low-voltage circuits that operate at a lower voltage (in this embodiment it is a maximum of 3.3 V) than that which acts on the piezoelectric element during detection of the ink level. The memory control circuit 501 can be configured in any way suitable for memory modules 203.

[0032] The first sensor connector 510 and the second sensor connector 550 of the carriage circuit 500 are electrically connected to the circuit generating the control impulses of the sensor 503. Connectors 510 and 550 are connected to the connectors 100 on the ink cartridge 100 via the contact mechanism 400 ( more specifically contact elements 410 and 450); contact element 450 of FIG. 3 corresponds to a portion of the control signal line of the second LDSP sensor, and contact element 410 corresponds to a portion of the control signal line of the first LDSN sensor. Via these connectors, the circuit generating sensor control pulses 503 energizes sensor 104 or receives the output (response) from sensor 104. The sensor generating pulse control circuit 503 includes cartridge detection circuit 503a and ink level detection circuit 503b.

[0033] During the detection process of whether the ink cartridge is mounted in the holder 4, the detection circuit of the cartridge 503a is designed to send the appropriate signal (voltage) through connectors 510, 550. Then, after receiving via connectors 510, 550 the response to the sent signal (voltage) , the cartridge detection circuit 503a detects whether the printed circuit board 200 is correctly connected to the printer, i.e., whether the printer currently has an ink cartridge 100. The 503b ink level detection circuit is designed to send a control voltage through

VP / 2126 / AW

3162 316 656Β1 connectors 510, 550. Next, the ink level detection circuit 503b detects the ink level by collecting through the connectors 510, 550 information about the frequency or amplitude of the waveform that reflects the voltage passing through the electrodes of the piezoelectric element. The detailed course of this process is described later. In the present embodiment, the sensor 104 is a high voltage circuit designed to receive a higher voltage (in this embodiment it is a maximum of 40 V) than the memory modules 203. The cartridge detection circuit 503a and the ink level detection circuit 503b can be configured according to various configuration schemes . For example, you can use a configuration consisting of a combination of logic circuits. You can also use a computer as a circuit that generates control pulses for the 503 sensor. In the present embodiment, an ASIC integrated circuit has been used as the carriage circuit 500 (including the circuit generating the control pulses of the sensor 503).

[0034] The carriage circuit 500 is connected to the main control circuit 40 via a bus B, of which the flexible conduit 37 is a component (FIG. 1). The carriage circuit 500 operates according to the instructions of the main control circuit 40. In this embodiment, the printer 1000 is equipped with 400 contact mechanisms in a number corresponding to a series of ink cartridges. More specifically, six ink cartridges 100 are mounted in carriage 3 (FIG. 1), which is equipped with six contact mechanisms 400. Furthermore, in the present embodiment, six ink cartridges 100 use the same carriage circumference 500. Carriage circumference 500 uses several ink cartridges 100 one at a time. Based on the ID number (ID number), the memory control circuit 501 selects one memory module 203 that will be used in further processing (described in detail later). The control pulse generating circuit of the sensor 503 selects one of the sensors 104 via a switched (invisible) circuit that is connected to the carriage circuit 500. [0035] The main control circuit 40 is a computer consisting of a CPU and memory (ROM, RAM, etc.) . The memory stores the M10 cartridge detection module, the M20 ink level detection module, and the M30 memory control module. In this document, modules M10 to M30 will be named respectively: first module M10, second module M20 and third module M30. M10 to M30 modules are computer programs designed for use by the CPU. The implementation of processes by the CPU using these three modules will be referred to in this document as the "implementation of modular processes". The processes implemented by the M10 to M30 modules will be described in more detail later.

[0036] As shown in FIG. 2 and 3, the main control circuit 40 is connected to the carriage circuit 500 via bus B. The main control circuit 40 supplies power potential, ground potential and data (e.g. indicating the desired command process sent from the main control circuit to the carriage circuit, data required for implementation such a process, ID numbers etc.) to carriage circuit 500 via bus B. The carriage circuit 500 sends data to the main control circuit 40 via bus B.

100 mounted in the carriage 3. In the drawing the directions X, Y and Z are marked. The direction X will also be called "direction + Χ" and the direction opposite to the direction X will be called "direction -X". This naming convention will also be used for directions Y and Z.

[0038] In the drawing, the Z direction determines the mounting direction of the ink cartridge 100. The ink cartridge 100 is mounted in the carriage 3 by moving the ink cartridge 100 in the Z direction. The ink supply nozzles 6 are located along the bottom wall 4wb (wall extending in the + Z direction) of the handle 4. The ink nozzles 6 are directed in the -Z direction. The contact mechanisms 400 are located along the front wall 4wf (wall extending in the Y direction) of the handle 4. The Y direction indicates the direction perpendicular to the Z mounting direction. In this embodiment, six ink supply nozzles 6 and six contact mechanisms 400 are aligned with each other in the X direction (from -X to + X), respectively. The X direction is perpendicular to both the Z direction and the Y direction. Six cartridges are installed side by side in the X direction (invisible).

[0039] FIG. 6A and 6B are perspective views of the ink cartridge 100, and FIG. 7A and 7B are front perspective views of the ink cartridge 100. The directions X, Y and Z indicated in the drawing refer to the directions of the ink cartridge 100 mounted in the carriage 3 (FIG. 4). The front surface of the ink cartridge 100 points in the + Z direction (surface perpendicular to the Z direction, which is also the bottom wall 101wb marked in FIG. 6A) is directed towards the bottom wall 4wb of the carriage 3. The front surface of the ink cartridge 100 points in the -Y direction (surface perpendicular to the direction Y, which is also the front wall 101wf marked in FIG. 6A) is directed towards the contact mechanism 400 of the carriage 3 .

[0040] The ink cartridge 100 includes a housing 101, a sensor 104 and a printed circuit board 200. The ink chamber 120 for storing ink is located inside the housing 101. The sensor 104 is attached to the interior of the housing 101. The housing 101 has a front wall 101wf (wall in the direction of - Y), bottom wall 101wb (wall in the + Z direction) and back wall 101wbk (wall in the + Y direction). The front wall 101wf connects to the bottom wall 101wb (in this embodiment, as a rule, at a right angle). The circuit board 200 is attached to the front wall 101wf. The connectors 210 to 270 are arranged on the outer surface of the circuit board 200 (surface facing the contact mechanism 400 (FIG. 4) of the printer 1000. The ink supply connector 110 is located on the bottom wall 101wb closer to the front wall 101wf than the back wall 101wbk (i.e. wall in the + Y direction) that faces the front wall 101wf.

[0041] On the front wall 101wf there are two protruding elements P1 and P2. These projections P1 and P2 are directed in the -Y direction. The construction of the H1 hole and the H2 notch on the printed circuit board 200 allows them to be connected to the protruding elements P1 and P2. The protruding elements P1 and P2, the opening H1 and the notch H2 serve as elements to prevent incorrect assembly, preventing the printed circuit board from being installed in the wrong position. The H1 hole is located in the middle of the lower edge (edge ​​in the + Z direction) of the circuit board 200, and the notch H2 in the middle of the upper edge (edge ​​in the direction PZ / 2126 / AW

ΕΡ 2 316 656 Β1

Z) printed circuit board 200. After mounting the printed circuit board 200 on the front wall 101wf, the protruding parts P1 and P2 pass through the opening H1 and the cut H2, respectively. The ability to mount the circuit board 200 in the wrong position on the front wall 101wf is limited by the contact of the H1 hole with the protruding element P1 and the contact of the notch H2 with the protruding element P2. After mounting the printed circuit board 200 on the front wall 101wf, the ends of the protruding elements P1 and P2 are bent. More specifically, the ends of the protruding elements P1 and P2 are bent under the influence of heat, so that the protruding elements P1 and P2 and the printed circuit board are tightly joined together by thermoplastic bending. The circuit board 200 is thus attached to the front wall 101 PE.

[0042] In addition, there is a protruding connector 101e on the front wall 101wf. The combination of the protruding connector 101e and the handle 4 (FIG. 4) does not allow the ink cartridge 100 to accidentally detach from the handle 4.

[0043] The ink supply connector 110, which acts as a print material supply connector, is located on the bottom wall 101wb. Ink supply connector 110 connects to ink chamber 120. Ink supply connector 110 and ink chamber 120 will be collectively referred to as "ink container 130". The opening 110op in the ink supply connector 110 is sealed with foil 110f. This prevents ink leakage from the ink supply connector 110. When mounting the ink cartridge 100 into the carriage 3 (FIG. 4), the closure (foil 110f) is pierced to insert the ink supply nozzle 6 into the ink supply connector 110. The ink in the ink chamber 120 (FIG. 6A) is fed to the printer 100 through the ink supply nozzle 6. The center line CL marked in FIG. 7B marks out the center axis of the ink supply connector 110. When the ink cartridge 100 is properly installed (i.e. its correct positioning) in carriage 3, center line CL is in line with the center axis of the ink supply nozzle 6. Ink cartridge 100 is an ink supply system (or more generally a print material supply system). [0044] FIG. 8 is an illustration depicting the process of mounting the ink cartridge 100 in the carriage 3. FIG. 9 is an illustration of the ink cartridge 100 mounted in the carriage 3. In these drawings, the ink cartridge 100 and carriage 3 are shown in cross-section. This cross-section is perpendicular to the direction X.

[0045] When assembling the ink cartridge 100, it is first placed above the handle 4 (in the -Z direction) so that the ink supply connector 110 points towards the ink supply nozzle 6. Then the ink cartridge 100 is mounted in the holder 4 by moving the cartridge 100 in the Z mounting direction. As a result, the protruding connector 101e on the ink cartridge 100 engages with the protruding connector 4e on the handle 4. The ink supply nozzle 6 enters the ink supply connector 110. The ink supply connector 110 has an oval gasket 112 at the opening 110op. Made of flexible material, such as rubber, gasket 112 has been designed to form a tight connection with the ink supply nozzle 6 and prevent ink leaks. In this way, the seal 112 forms the connection between the ink supply connector 110 (opening 110op) and the ink delivery nozzle 6.

VP / 2126 / AW

EP 2 316 656 Β1 [0046] As shown in FIG. 8, above the seal 112 there is a valve assembly 113. The valve assembly 113 is moved towards the seal 112 by a spring (invisible). After disconnecting the ink cartridge 100 from the handle 4, the valve assembly 113 contacts the gasket 112 and ensures that the ink supply connector 110 is sealed. Thus, the risk of ink leaking from the ink supply connector 110 is limited even if the ink cartridge 100 is detached from the holder after mounting the ink cartridge 100 in the holder 4 and breaking the film 110f.

[0047] When the ink cartridge 100 is mounted in the holder 4 as shown in FIG. 9, the contact mechanism 400 will be located in front of the circuit board 200 (in the -Y direction). On the contact mechanism 400, a plate 500b is mounted facing in the -Y direction. Carriage circuit 500 is mounted on board 500b. Connectors 210 to 270 of circuit board 200 are electrically connected respectively to connectors 510 to 570 of carriage circuit 500 via contact mechanism 400 (this issue will be discussed in more detail later). The mounting direction Z corresponds to the mounting direction when mounting (connecting) the circuit board 200 in a 1000 printer.

[0048] When the ink cartridge 100 is mounted in the holder 4, the ink supply nozzle 6 pushes the valve assembly 113 up so that the valve assembly 113 separates from the seal 112. In this way, the ink chamber 120 and the ink supply nozzle 6 combine to thereby allow supplying 1000 of the ink inside the ink chamber 120 to the printer.

[0049] FIG. 10A and 10B are perspective views of a circuit board 200. FIG. 10C shows a front view of the circuit board 200 looking in the Y direction (from -Y in the + Y direction), FIG. 10D shows a side view of the circuit board 200 looking in the -X direction (from + X in the -X direction), and FIG. 10E shows a rear view of the circuit board 200 looking in the -Y direction (from + Y in the -Y direction). The directions X, Y and Z in the drawing show the directions after mounting the ink cartridge 100 in the carriage 3 (FIG. 4).

[0050] On circuit board 200, connectors 210 to 270 and memory module 203 are arranged on the insulating board 205. Board 205 includes a memory module 203 located on the back side of the board 205 and connectors 210 to 270 located on the front side of the board 205. Plate 205 is a flat plate perpendicular to the Y direction, generally rectangular in shape, with two sides parallel to the X direction and two to the Z direction. The front side FS means the surface facing forward (in the -Y direction), while the rear side BS means the surface facing backwards (in the + Y direction). Plate 205 has a H1 hole and a H2 notch. Connectors 220, 230, 240, 250, 260, 270 are connected to the corresponding fields Pvdd, Pvss, Psda, Prst, Psck (FIG. 3) located on memory module 203 via electrically conductive paths (invisible). For example, the electrically conductive paths may include a through hole in the plate 205, an electrically conductive pattern formed on the surface or inside the plate 205, and a connecting wire that is the connection between the electrically conductive pattern and the field on the memory module 203. In this embodiment, the surface memory module 203 on board 205 is coated with RC resin.

VP / 2126 / AW

ΕΡ 2 316 656 Β1 [0051] FIG. 10C depicts the front side FS of the circuit board 200. The seven connectors 210 to 270 are arranged to form a rectangular shape. Connectors 210 to 270 are arranged in such a way as to form two straight lines L1 and L2 that extend in the X direction (from -X in the + X direction) perpendicular to the mounting direction Z of the ink cartridge in holder 4. The first line L1 corresponds to a hypothetical straight line (segment) perpendicular to the mounting direction Z, formed or delimited by a series of contacts from 21 Oc to 250c, which include contact 21 Oc, with the first sensor 210 connecting to contact 410, and contact 250c, with what the second sensor 250 connects to contact 450. The second line L2 corresponds to a hypothetical straight line (section) perpendicular to the mounting direction Z, formed or delimited by contact 260c, where the reset connector 260 connects to contact 460, and contact 270c, with clock connector 270 connecting to contact 470. The first line L1 is located on the front side (front side) in relation to the mounting direction Z (i.e. end face with respect to another line (in this case the second line L2) in the direction of movement during assembly). When the ink cartridge 100 (FIGS. 8, 9) is properly mounted (i.e., closely adheres) in the holder 4, the straight line that is closest to the ink supply connector 110 (opening 110op) from this series of straight lines is referred to as the first line L1. The connectors whose contacts form the first L1 line are, in order from the left in the drawing (edge ​​in the -X direction), the first sensor connector 210, the power connector 220, the ground connector 230, the data connector 240 and the second sensor connector 250. The connectors that form the second line L2 is, from the left in the figure, the reset connector 260 and the clock connector 270. Connectors 210 and 250 can be omitted. In this case, the contact connectors that make up the first L1 line should include three connectors that connect to the memory module 203, more specifically the power connector 220, ground connector 230 and data connector 240. As in the example shown, the first L1 line can be formed through the contact connectors of all or some of the connections connected to the memory module 203. [0052] FIG. 10E shows the back side BS of the circuit board 200. On the back side BS there are two 21 Ob connectors, 250b. Connectors 21 Ob, 250b, respectively, are electrically connected with continuous connection with connectors 210, 250 on the front side of FS. One of the sensor electrodes 104 is connected to the 21 Ob connector and the other electrode of the sensor 104 is connected to the connector 250b.

[0053] FIG. 11A is a rear view of the contact mechanism 400 looking in the -Y direction (from + Y in the -Y direction), and FIG. 11B is a side view of the contact mechanism 400 looking in the -X direction (from + X in the -X direction). FIG. 12 is a perspective view of the contact mechanism 400. The contact mechanism 400 includes a support element 400b and seven contact elements 410 through 470. Inside the support element 400b there are first slots 401 and second slots 402 that are arranged side by side in the X direction (from -X in the + X direction). The second slots 402 are directed in the -Z direction relative to the first slots 401. The contact elements 410 to 470 respectively lie in a recess inside the slots 401, 402 so that they correspond to the terminals 210 to 270 on the circuit board 200 (FIG. 10C) . Each of the contact elements 410 to 470 conducts electricity and is resilient. The second slot 402a on the + X side and the second slot 402b on the -X side are not used and can be omitted.

[0054] As shown in FIG. 11B, contact elements 410 to 470 at one end of the support 400b protrude in the + Y direction. The first end of the protruding element is bent into

VP / 2126 / AW

316 2 316 656 stronę1 side of circuit board 200 so as to connect to the corresponding connector from connectors 210 to 270 on circuit board 200. FIG. 11A shows parts 41 Oc to 470c of contact elements 410 to 470 that connect to connectors 210 to 270. These contact elements 41 Oc to 470c function as device side connectors providing electric connection between the printer 1000 and connectors 210 to 270 on the circuit board 200 . These 41 Oc to 470c contact elements will also be called device side 41 Oc to 470c connectors.

[0055] At the same time, as shown in FIG. 11B, contact elements 410 to 470 at one end of the support 400b protrude in the -Y direction. The other end of the protruding element is bent toward the plate 500b so as to connect to the corresponding connector from connectors 510 to 570 on the plate 500b (connectors 510 to 570 on the circumference of the carriage 500). Circuit-shaped carriage 500 connectors 510 to 570, although omitted from the drawing, are arranged similarly to connectors 210 to 270 shown in FIG. 10C. These connectors 510 to 570 are located on the perimeter of the carriage 500b on its side facing the contact mechanism 400.

[0056] FIG. 13A-13E illustrates the connection between contact elements 410 to 470 and connectors 210 to 270 and ink cartridge 100 (FIG. 8) after assembly. FIG. 13A to 13E show contact mechanism 400 and circuit board 200 looking in the -X direction (from + X in the -X direction). During assembly, the circuit board 200 shifts in the mounting direction Z. The spatial relationship between the circuit board 200 and the contact mechanism 400 changes as described in FIG. 13Ado13E.

[0057] First, as shown in FIG. 13B, the lower edge LE (edge ​​in the + Z direction) of the board 205 on the printed circuit board 200 connects to two contact elements 460, 470 that are rotated in the Z direction with respect to contact elements 410 to 450. Then, by moving the board 205 in + Z contact elements 460, 470 are pushed in the -Y direction. Contact elements 460, 470 are flexible and contacts 460c, 470c move in the + Y direction. Therefore, when contact elements 460, 470 (contacts 460c, 470c) engage with the front wall FS of plate 205, plate 205 moves in the + Z direction.

[0058] Then, as shown in FIG. 13C, the lower edge LE of the board 205 contacts five contact elements 410 to 450, which are shifted in the + Z direction. Contact elements 410 to 450 are also flexible, and the contacts 41 Oc, 450c move in the + Y direction. Therefore, when contact elements 410 to 450 (contacts 41 Oc to 450c) connect to the front wall FS of plate 205, plate 205 moves in the + Z direction. FIG. 13D shows the plate 205 further shifted in the + Z direction from the position shown in FIG. 13C. In the condition shown in FIG. 13D connector 230 has been moved between contact element 460 and contact element 470.

[0059] At this point, as shown in FIG. 13E, the process of assembling the ink cartridge 100 is over. In this state, contact elements 410 to 470 (41 Oc to 470c contacts) are connected to connectors 210 to 270 on the circuit board 200, respectively.

[0060] In FIG. 13E two distances Ds1, Ds2 are marked. The first distance Ds1 determines the distance by which contact elements 410 to 450 move on the front side of plate 205. The second distance Ds2 defines the distance by which contact elements 460 to 470 move on the front side of plate 205. As shown in the picture, the first distance Ds1 is less than

VP / 2126 / AW

ΕΡ 2 316 656 Β1 second distance Ds2. Thus, for contact elements 410 to 450, which correspond to the first line L1 (FIG. 10C) located in the front position (face side) in the mounting direction Z, the offset distance on the front side FS is smaller compared to other contact elements 460, 470 . As a result, foreign bodies such as dust settling on the front side of FS have a much lower chance of settling on contact elements 410 to 450 than on other contact elements 460, 470. This means that the probability of incorrect connection between contact elements 410 to 450 and connectors 210 to 250 are lower compared to other contact elements 460, 470.

[0061] All ink cartridges use the configuration described above.

A2. Cartridge detection:

[0062] FIG. 14 is a block diagram showing the process of cartridge detection. This process allows the 1000 printer to verify that the ink cartridge has been installed. This process is accomplished by the (first) M10 cartridge detection module and carriage circuit 500 (circuit generating sensor control pulses 503, FIG. 3). The procedure shown in FIG. 14 describes a process relating to a single ink cartridge. The first module M10 and carriage circumference 500 perform this process for all ink cartridges to be mounted in the holder 4 (FIG. 4) respectively. Thanks to this, the first M10 module verifies the assembly of all (six) ink cartridges. The first M10 module can perform this process using different synchronization schemes. For example, this process can be carried out cyclically or when the appropriate conditions are met (e.g. when the 1000 printer is powered on, when the 100 ink cartridge is replaced or when printing has started), it can also be performed in response to a user command.

[0063] In the initial Step S100, the first module M10 sends a signal (voltage) from the sensor connectors 510, 550 on the ink cartridge to detect the presence of the cartridge. More specifically, the first module M10 sends the command to send a single signal to the cartridge detection circuit 503a. This command contains the ID number of the ink cartridge. According to this command, the cartridge detection circuit 503a switches the switching circuit so that the sensor connectors 510, 550 are selected that are associated with the selected ID numbers, and then the selected sensor connectors 510, 550 send a signal (voltage). When the ink cartridge 100 is mounted, voltage is transmitted through the two electrodes of the sensor 104. In this way, the sensor 104 is charged.

[0064] In next Step S110, the first module M10 uses sensor connectors 510, 550 to receive a response signal (voltage). More specifically, the first module M10 sends a signal (voltage) receiving command to the cartridge detection circuit 503a. According to this command, the cartridge detection circuit 503a stops applying voltage, and then measures the voltage between the two sensor connectors 510, 550. Then, the cartridge detection circuit 503a transmits the measured voltage information to the first module M10.

[0065] In the next Step S120, the first module M10 decides if the measured voltage is higher than the set threshold value. The voltage of the charged sensor 104 is measured if the cartridge

VP / 2126 / AW

ΕΡ 2 316 656 Β1 ink 100 has been installed. The absolute value of the measured voltage (called the first voltage) is greater than zero. If the ink cartridge 100 is not installed, the measured voltage is generally zero. The threshold value greater than zero and less than the value of the first voltage is determined empirically in advance. In this way, if the absolute value of the measured voltage is greater than the threshold value, the first module M10 decides that the ink cartridge 100 is mounted (Step S130). If the absolute value of the measured voltage is equal to or less than the threshold value, the first module M10 decides that the ink cartridge 100 is not mounted (Step S140). At this point, the first M10 module ends the process.

[0066] In a preferred embodiment, if no ink cartridge has been mounted at one or more mounting points, the first module M10 performs the process relating to the non-installed cartridge (s). An example of such a process may be, for example, pausing the printing process or starting a process to alert the user of the lack of a mounted cartridge.

A3. Memory control:

[0067] FIG. 15 is an illustration showing the configuration of memory module 203 in the present embodiment. The 203 memory module is a semiconductor integrated circuit that includes an I / O circuit. IOC, MLM logic module, matrix of non-volatile MCA memory cells and five fields (I / O connectors) Pvdd, Prst, Psck, Psda and Pvss. The MLM logic module contains the MLM1 ID comparator, MLM2 address generator and MLM3 read / write driver. In response to a command from an external device (e.g., the printer driver 1000 of FIG. 3; forming the entire main control circuit 40 and carriage circuit 500), the MLM logic module writes data to the MCA memory cell matrix or reads data from the MCA memory cell matrix (issue this will be discussed in more detail later.) I / O circuit IOC includes five lines Lvdd, Lrst, Lsck, Lsda, Lvss; three buffer circuits MBrst, MBsck, MBsd and a PC protection circuit. The fields Pvdd, Prst, Psck, Psda, Pvss are properly connected to the MLM logic module using the lines Lvdd, Lrst, Lsck, Lsda, Lvss. The Lvdd power line receives the VDD power potential. The Lrst reset line receives the RST reset signal. The Lrst reset line is equipped with the first MBrst buffer circuit. The Lsck clock line receives the SCK clock signal. The Lsck clock line is equipped with an MBsck second buffer circuit. The Lsda data line is used to send and receive SDA data signals. The Lsda data line is equipped with the MBsda third buffer circuit. The Lvss grounding line receives the VSS ground potential. The Pvdd, Prst, Psck, Psda, Pvss fields are electrically connected with connectors 220, 260, 270, 240, 230 on the printed circuit board 200, respectively.

[0068] The PC protection circuit protects the internal circuits of memory module 203 (including MLM logic module and MCA memory cell matrix) against incorrect input signals, such as electrostatic discharge reaching the fields. In the present embodiment, the PC protection circuit comprises protection diodes D1 to D6. Three of them D1, D3, D5 connect to the Pvdd power field (Lvdd power line) at the cathode. These diodes D1, D3, D5 connect

PZZ2126 / AW

ΕΡ2 316 656Β1 with Prst, Psck, Psda (Lrst, Lsk, Lsda lines) respectively at the anode. Three other diodes D2, D4, D6 connect to the Pvss ground field (Lvss ground line) at the anode. These diodes D2, D4, D6 connect respectively to the fields Prst, Psck, Psda (lines Lrst, Lsk, Lsda) at the cathode.

[0069] FIG. 16 is a signal synchronization table showing the operation of the memory module 203. The signals (VDD supply potential, RST reset signal, SCK clock signal, SDA data signal) appearing on the fields of memory module 203 (FIG. 15) and operations of memory module 203 are shown in the drawing . In the present embodiment, both reading data from the MCA memory cell matrix of the memory module 203 and writing data into the MCA memory cell matrix is ​​performed as shown in the diagram in FIG. 16. In the figure, level H means high potential (about 3.3 V) and level L means low potential (0 V). The reference value for these potentials is the VSS ground potential. The arrows below the symbols that specify the signals indicate the direction of the signal (data) flow. The right arrow indicates flow from memory control circuit 501 (FIG. 3) to memory module 203 and the left arrow indicates flow from memory module 203 to memory control circuit 501. SDA data signals can be sent in both directions.

[0070] In the present embodiment, access to memory module 203 (FIG. 15: matrix of MCA memory cells) is based on sequenced access. The memory address you want to access is updated in the assigned order from the assigned start address based on the SCK clock signal. Because in the present embodiment, the write operations in the memory cell matrix and the read operations from the memory cell matrix are carried out collectively in rows, the memory address is the address indicating the row. You can access only one memory cell at a time, starting from Row 0 in the MCA memory cell matrix. The size of data contained in a single row (corresponding to one word) is expressed in n bits (n is an integer equal to or greater than 1, for example n = 32). The MLM2 address generator updates the selected memory address in the order of Row 0, Row 1, Row 2 and so on whenever it receives n pulses of the SCK clock signal. The memory module ID number 203 is stored in advance in Row 0. In the present embodiment, the ID number is written with three bits. The physical locations of the rows in the memory matrix do not have to be in the same order as the row access sequence.

[0071] When access to memory module 203 (FIG. 15) is needed, memory control circuit 501 (FIG. 3) first sets the VDD supply potential to level H. Then control circuit 501 sets the RST reset signal to level H. In this embodiment, when the RST reset signal is set to level H (a predetermined level different from the VSS ground potential value), memory module 203 operates in synchronization with the SCK clock signal. If the RST reset signal is set to a level other than the H level (e.g., the same level as the VSS ground potential), memory module 203 suspends operation. The memory control circuit 501 can then reset all memory module processes by changing the RST reset signal from level H to level L (this topic will be discussed in more detail later).

VP / 2126 / AW

ΕΡ 2 316 656 Β1 [0072] Then, memory control circuit 501 (FIG. 3) sends a clock signal SCK to clock connector 270 on circuit board 200 (FIG. 15). In synchronization with the SCK clock signal, the memory control circuit 501 sends the n-bit SDA data signal to data connector 240. The first three bits of n-bit data encode the ID number of memory module 203 to be called. The next bit codes the command. The command applies to either reading (R) or writing (W) data. For example, level L corresponds to command R and level H corresponds to command W. Other bits are padding data.

[0073] In the time it takes to receive the initial n clock pulses CP1, the MLM logic module (FIG. 15) performs the following process. The MLM2 Address Generator (FIG. 15) creates a memory address corresponding to Row 0. The MLM3 read / write controller reads the generated address data (Row 0 data) from the MCA memory cell matrix (FIG. 16: Step 10) Next, the MLM1 ID comparator decides whether its own ID number read from the MCA memory cell matrix is ​​the same as the ID number indicated by the memory control circuit 501 (FIG. 3) (Step S20). If its own ID number differs from the indicated ID number, the MLM logic module suspends processing and goes into operational mode (standby mode), in which the reset signal is monitored. If its own ID number is the same as the indicated ID number, the MLM logical module continues processing. By switching processes depending on the ID number, designated by memory control circuit 501, memory module 203 performs processes depending on the commands from memory control circuit 501. In the next Step S30, the MLM3 read / write controller decides whether the command specified by the SDA data signal is read (R) or write (W) data. After receiving the initial n clock pulses, the MLM logic module starts the process indicated in the command. [0074] For the data read command, the MLM logic module (FIG. 15) performs the process from Step S41 to Step S4k in synchronization with the clock signal SCK. As mentioned earlier, each time the MLM2 address generator (FIG. 15) receives n clock pulses, it increases the memory address values ​​by one row, starting with Row 0. The MLM3 read / write controller then reads the address data indicated by the MLM2 address generator from the MCA memory cell matrix. Via the SDA data signal, the MLM3 read / write controller sends the read data one bit in sync with the SCK clock signal. For example, based on the second series of n clock signals CP2, the MLM3 read / write controller sends data from Row 1 (Step S41). More specifically, when the output clock signal from the second series of n CP2 clock signals is emitted, the MLM3 read / write controller reads Row 1 from the memory cell matrix and in synchronization with each clock signal from the n series of CP2 clock signals sends the read data n bits to the memory control circuit 501. Memory control circuit 501 (FIG. 3) synchronized with the clock signal, the SCK receives one data bit at a time from rows from Row 1 to Row k (k is an integer equal to or greater than 1) that are stored in the matrix of MCA memory cells. In the embodiment shown in FIG. 16 after receiving data from Row k, memory control circuit 501 stops sending the SCK clock signal.

[0075] For the data write command (W), the MLM logic module (FIG. 15) performs the process from Step S51 to Step S5k in synchronization with the clock signal SCK. Using the SDA data signal and working in synchronization with the SCK clock signal, memory control circuit 501 (FIG. 3)

VP / 2126 / AW

EP 2 316 656 przes1 sends to the MLM logic module one bit containing data to be stored in the MCA memory matrix. The MLM3 read / write driver then stores the received data in the MCA memory cell matrix at the address specified by the MLM2 address generator. For example, in synchronization with the second series of n clock signals CP2, the MLM3 read / write controller writes the received data in Row 1 to the MCA memory cell matrix (S51, S51w). In the embodiment shown in FIG. 16 after saving the data in the memory cells of Row k (Step S5kw), the memory control circuit 501 stops sending the SCK clock signal.

[0076] As will be described later, the ink cartridge 100 may not be in the correct position inside the holder 4. Such incorrect assembly may theoretically cause the data connector 240 on the circuit board 200 (FIG. 2) to detach from the element contact 440 located on contact mechanism 400. If the VDD supply potential, the RST reset signal and the SCK clock signal are sent to memory module 203 (FIG. 15) in the normal way, the MLM logic module can write data according to the Lsda data line potential (i.e. erroneous data) in the MCA memory cell matrix (for example, the Lsda data line voltage may be the same as the Lvss ground line potential). The memory module 203 may also not work properly or stop working for many other reasons that are not limited to those mentioned above (this topic will be discussed in more detail later).

[0077] After suspending the transmission of the SCK clock signal, memory control circuit 501 (FIG. 3) changes the RST reset signal from level H to level L. In this way, all modules 203 reset. More specifically, the MLM2 address generator resets memory addresses to Row 0. When the MLM logic module receives the next RST reset signal (level H), SCK clock signal and SDA data signal, it will proceed with the process starting from Step S10 shown in FIG. 16. When the memory control circuit 501 sets the RST reset signal to L level, the VDD supply potential will also be set to L level. In this way, all 203 modules suspend their operation.

[0078] Memory control circuit 501 (FIG. 3) operates according to the commands of the memory control module M30 (third module). The third module M30 connects to the memory module 203 of each of the six ink cartridges 100 mounted in the holder 4 (FIG. 4). Because the information is stored in memory modules 203, it is not possible to use various types of information about the inks contained in the ink cartridges 100. For example, this information may reflect the type of ink. The third M30 module can also read ink type information from memory module 203 and confirm that the appropriate ink cartridges are installed. You can also use information about the level of ink consumption (for example, the number of drops) because the 1000 printer has an ink cartridge installed. The third module M30 can also periodically update information about the level of ink consumption stored in memory module 203, updating this information during printing, after cleaning the nozzle, when the user turns off the printer 1000, etc. Thanks to this, the third module M30 is able to determine the ink level by reading information about ink consumption level from memory module 203. A third module M30 can access memory module 203 using various synchronization schemes.

B. Features of this embodiment:

[0079] The present embodiment 1 described above has various features. These features are described below.

B1. Feature 1:

[0080] The present embodiment has the following feature: contact 220c at the power connector 220 that transmits the VDD power potential to the memory module 203 is located on the first straight line L1 (FIG. 10C). Memory module 203 receives VDD power potential through contact 220c on power connector 220.

[0081] The first straight line L1 is in the leading position (on the front side) relative to the other straight lines (in this embodiment the second straight line L2). The front position indicates the front position when the ink cartridge 100 is set to allow installation in the 1000 printer. This means that the front position (front side) represents the front position (front side) in the Z mounting direction.

[0082] The benefits are discussed below. FIG. 17A and 17B show the incorrect mounting position of the ink cartridge 100 mounted in the holder 4. FIG. 17A and FIG. 17B show the ink cartridge 100 and the handle 4 in cross section (cross section is perpendicular to the direction X). The ink supply nozzle 6 of the holder 4 is inserted into the ink supply connector 110 of the ink cartridge 100. In this way, the ink supply connector 110 of the ink cartridge 100 is attached to the ink supply nozzle 6 of the holder 4. As a result, the ink cartridge 100 may swing around the ink supply connector 110. In the opening 110op of the ink supply connector 110, the seal 112 contacts the ink supply nozzle 6. Therefore, the center of movement MC of the ink cartridge 100 is on the center line CL near the contact section between the seal 112 and the ink supply nozzle 6.

[0083] FIG. 17A and FIG. 17B depict the ink cartridge 100 bias in the + Y direction relative to the Z axis. This bias can be due to a variety of reasons. For example, when mounting the ink cartridge 100 in the holder 4 (printer 1000), the user may incorrectly mount the ink cartridge 100 in the holder 4 (in a tilted position). Since the center of gravity CF of the ink cartridge is on the + Y side relative to the centerline CL, the connectors 210 to 270 of the ink cartridge tend to diverge from contact elements 410 to 470.

[0084] FIG. 17A shows the distance da between contacts 21 Oc to 250c on the first line L1. The angle AG indicated in the figure indicates the deviation (rotation angle) of the ink cartridge 100 relative to the ink supply connector 110. The first distance Ra is the distance between the ink supply connector 110 (center of rotation MC) and the contacts 21 Oc to 250c. [0085] FIG. 17B shows the distance db over which contacts 260c, 270c move on the second line L2.

VP / 2126 / AW

ΕΡ2 316 656Β1

The second distance Rb is the distance between the ink supply connector 110 (center of rotation MC) and contacts 260c, 270c. The rotation angle of the ink cartridge 100 is designated AG, as in FIG. 17A.

[0086] If the angle AG is large, the contacts 21 Oc to 270c may separate from contact elements 410 to 470. In this case, the first L1 line is less likely to separate from the contact elements than with the second L2 line. The reasons are as follows: In this embodiment, the opening 110op is shifted further to the mounting direction Z compared to the series of contacts 21 Oc to 270c of the series of connectors 210 to 270 (FIG. 7.17). The first L1 line is located on the front side in the Z mounting direction relative to the other lines (in this embodiment relative to the second L2 line); it can also be said that in the present embodiment of the series of lines, the first line L1 is the line closest to the opening 110op (FIG. 7). This means that the first distance Ra is smaller than the second distance Rb. In this situation, for a given angle AG, the distance between the first L1 line and contact elements 410 to 450 (first distance da) is smaller than the distance between the second L2 line and contact elements 460, 470 (second distance db). The location of the 110op hole further in the Z mounting direction relative to the location of the 21 Oc contacts to 270c means that with respect to the position parallel to the Z mounting direction, the location of the 110op hole lies further towards the mounting direction Z than the corresponding 21 Oc contact locations 270c.

[0087] FIG. 18 shows an enlarged view of the surroundings of the 21 Oc contacts to 270c. FIG. 18, like FIG. 17A and FIG. 17B, ​​shows the deflected ink cartridge 100. As shown, as the angle AG increases, the second line L2 separates from the contact elements earlier than the first line L1.

[0088] In this way, from the series of lines L1, L2 on the circuit board 200, the line with the least chance of faulty connections with contact elements is called the first line L1. Therefore, preferably, of the series of contacts on the circuit board 200, those contacts that can cause serious problems due to faulty connections are on the first line L1. Thus, in the present embodiment, the contact 220c supporting the VDD supply potential is located in the first line L1 (FIG. 10C).

[0089] FIG. 19 is an illustration of a comparative example. The drawing shows connectors 210 to 270 and the memory module 203 on the circuit board. In the configuration shown in FIG. 19 The VDD supply potential contact is on the second L2 line (contact 270c), while the RST reset signal contact and the SDA data signal contact are on the first L1 line (contacts 230c, 240c). More specifically, the Pvdd power field is connected to connector 270, and the Prst reset field and Psda data field are connected to connectors 230, 240, respectively.

[0090] In the configuration shown in FIG. 19, it must be assumed that the ink cartridge is deflected enough so that the second line L2 and contact elements 460, 470 (FIG. 18) do not touch each other. It should also be assumed that under these conditions memory control circuit 501 (FIG. 3) attempts to access memory module 203 (FIG. 16). In this case, the supply potential to the memory module 203 via connector 270 is interrupted. Instead, the Lvdd power line of memory module 203 receives the RST reset signal via protection diode D1. However in

VP / 2126 / AW

ΕΡ 2 316 656 Β1 compared to the RST reset signal, the voltage supplied in this place is lower by the value corresponding to the voltage transmitted by the protection diode D1 (i.e. by about 0.6 V).

[0091] Assume that the acceptable operating voltage range of memory module 203 is from 2.7 V to 3.3 V. In this case, the value of the RST reset signal voltage sent to terminal 230 via memory control circuit 501 may also be from 2.7 V up to 3.3 V. If the RST reset signal voltage is 3.3 V, a voltage of 2.7 V is applied to the Lvdd power line. Under these conditions, the 203 memory module can work. However, because the voltage on the Lvdd power line is close to the lower limit of the acceptable range, memory module 203 may become unstable. If the RST reset signal voltage is even lower (e.g. 2.7 V), in some cases the memory module 203 may not be able to work at all. Under such conditions, it is likely that the MLM logic module will not be able to generate the correct control signal for the MCA memory cell matrix. For example, it is possible that in response to a write command, the MLM logic module will write incorrect Dwe data that differs from the correct Dw data written on the MCA memory cell matrix. It is also possible that in response to a read command, the MLM logic module will send incorrect Dre data that is different from the correct Dr. And so, seemingly ordinary surgery can actually be a wrong operation.

[0092] In the present embodiment, the contact for supplying the VDD supply potential to the memory module 203 is on the first line L1 (contact 220c). In this way, it is possible to minimize the likelihood of performing an erroneous operation, as described above, caused by unstable operating voltage.

[0093] As shown in FIG. 13E, in the present embodiment, the first contact elements 410 to 450 corresponding to the first line L1 (FIG. 10C) in the front position in the Z mounting direction move a smaller distance on the front side FS compared to other contact elements 460, 470 (Ds1 &lt;Ds2). Therefore, the probability of a faulty connection is lower for the first L1 line than for the second line. It is preferred that the contacts that can cause serious failures due to a faulty connection (e.g. contact receiving the VDD supply potential) are on the first line L1.

[0094] In the event of a faulty connection on the reset connector 260 or the clock connector 270, the memory module 203 will be reset or its operation will be suspended to minimize the probability of writing erroneous data compared to the case where the faulty connection occurs on the power connector 220. Thus, in the present embodiment, the contacts 260c, 270c of the connectors 260, 270 are on the second non-guide line (in this embodiment it is the second line L2).

[0095] As shown in FIG. 17A and 17B, in this embodiment, the 21 Oc to 270c contacts (connectors 210 to 270) are on the same wall (front wall 101wf) of the ink cartridge 100. The ink supply connector 110 is located on the bottom wall of the 101wb ink cartridge 100. Including In this case, the ink supply connector 110 is located at an off-center point or shifted on the bottom wall 101wb toward the front wall 101wf. More specifically, in this embodiment, the ink supply connector 110 on the bottom wall 101wb is facing the front wall 101wf from

VP / 2126 / AW

ΕΡ 2 316 656 Β1 view of the intermediate IP position lying between the first edge E1, which is closest to the front wall 101wf (place of connection with the front wall 101wf) and the second edge E2 located on the opposite side from the first edge E1 (place of connection with the rear wall 101wbk) . The mounting direction Z is in accordance with the direction of gravity. As a result, the center of gravity CF of the ink cartridge 100 is on the + Y side (opposite the side on which the connecting mechanism 400 is located) with respect to the center line CL (center MC). The center of gravity CF is the center of gravity of the ink cartridge 100 profile when looking at the ink cartridge 100 in the -X direction from the + X side. Intermediate position IP coincides with the position of the center of gravity CF projected on the bottom wall 101wb in the Z mounting direction. According to the above configuration, the ink cartridge 100 tends to deflect in such a direction that the 21 Oc to 270c contacts separate from contact elements 410 to 470. Under these conditions, the introduction of Feature 1 described above provides significant benefits. Since the ink supply connector 110 is closer to the first edge E1 (connectors 210 to 270) than the second edge E2 (rear wall 101wbk), the distances da, db are smaller for a given angle AG compared to the situation where the ink supply connector 110 is closer the second edge E2 than the first edge E1. Hence, in the event that the ink cartridge 100 is deflected, the likelihood of a faulty connection between connectors 210 to 270 (21 Oc to 270c contacts) and 21 Oc to 270c contact elements is limited.

B2. Feature 2:

[0096] An additional feature of the present embodiment is: contact 240c on data connector 240, which receives SDA data signals from an external device (control unit (forming the entire main control circuit 40 and carriage circuit 500) of the printer 1000) and sends SDA data signals to the device external (printer control assembly 1000) located on the first line L1 (FIG. 10C). Memory module 203 receives SDA data signals and sends SDA data signals through contact 240c of this data connector 240.

[0097] FIG. 20 is an illustration depicting a structure different from that shown in Description 2. The figure shows connectors 210 to 270 on the circuit board and the memory module 203. In the structure shown in FIG. 20 The SDA data signal contact (contact 270c) is on the second line L2. More specifically, the Psda data field is connected to connector 270.

[0098] Suppose that in the structure shown in FIG. 20 the ink cartridge is deflected enough to disengage the connection between connector 270 and contact element 470 (FIG. 18). It should also be assumed that under these conditions memory control circuit 501 (FIG. 3) attempts to access memory module 203 (FIG. 16). Under these conditions, bidirectional transmission (sending and receiving) of SDA data signals via connector 270 is interrupted. Hence, if the memory module 203 receives the VDD supply potential, the RST reset signal and the SCK clock signal, it is able to operate, but cannot operate normally. It is possible, for example, that in response to a write command, memory module 203 will write incorrect Dwe data that differ from the correct data Dw. If there is no electrical connection to contact element 470 of the 1000 printer,

PZJ2t2Q / A \ N

The memory module 203 operates on the basis of data (erroneous data) according to the potential in the Psda data field (FIG. 15 - Lsda data line) which is separated from the contact element. The potential of the Lsda data line can be, for example, L. In this case, incorrect Dwe data can be data in which all bits are set to level L. Similarly, in the case of a response to a read command, it is possible that the data received by the memory control circuit 501 is incorrect Dre data that differs from the correct Dr read data (e.g., data in which all bits are set to L level). And so, seemingly normal work can really be wrong work.

[0099] In the present embodiment, the contact on the data connector for sending and receiving the SDA data signal (contact 240c) may be on the first line L1. As a result, the likelihood of the abovementioned irregularity decreases.

B3. Feature 3:

[0100] An additional feature of the present embodiment is the contact 270c on the clock connector 270 for receiving the clock signal. The SCK is on a line other than the first L1 line (in the present embodiment it is the second L2 line; FIG. 10C).

[0101] In the present embodiment, if the SCK clock signal is interrupted, the memory module 203 suspends its operation. Hence, in the case of a faulty connection on the clock connector 270, the probability of writing erroneous data in the memory module 203 is less compared to the case in which the faulty connection relates to the power connector 220 or data connector 240. Thus, by positioning contact 270c of a clock connector 270 on a line other than the first L1 line (e.g., on the second L2 line), as in the present embodiment, a series of contacts can be arranged among the line series without increasing the likelihood of writing erroneous data in the memory module 203. Thus, compared to the case where all of the series of contacts are on a single line, the lines may have a shorter length (i.e. the device may be more compact).

B4. Feature 4:

[0102] An additional feature of the present embodiment is contact 260c on the reset connector 260, which receives the RST reset signal, is on a different line from the first L1 line (in the present embodiment it is the second L2 line; FIG. 10C).

[0103] In the present embodiment, the memory module 203 has been designed in such a way that if the RST reset signal transmission is interrupted, the signal that goes to the memory module 203 from the reset field has a lower voltage value than the H level, and the memory module 203 or suspends operation or reset. Hence, in the case of a faulty connection connector reset 260, the probability of writing erroneous data in the memory module 203 is less than in the case of a faulty connection connector power 220 or data connector 240. Thus, by placing contact 260c of the reset connector 260 on a line other than the first line L1 (e.g. on the second L2 line), as in the present embodiment, a series can be arranged

VP / 2126 / AW

3162 316 656Β1 contacts among a series of lines without increasing the likelihood of writing erroneous data in the 203.1 memory module so compared to the case where all of the series of contacts are on a single line, the lines may have a shorter length (i.e. the device may be more compact).

B5. Feature 5:

[0104] An additional feature of the present embodiment is a series of 21 Oc to 270c contacts which is in the same plane (FIG. 10C) and when the center axis of the ink supply connector 110 (center line CL) in the direction (direction Y) perpendicular to this the plane (from + Y to Y) will be thrown onto this plane, the contacts furthest from the central axis CL are the contacts 21 Oc, 250c on sensor connectors 210, 250.

[0105] Sensor connectors 210, 250 are connectors through which the main control circuit 40 and carriage circuit 500 of the printer 1000 send to the circuit board 200 the detection signal of the assembly of the ink cartridge 100 (FIG. 3). As shown in FIG. 21 if the ink cartridge 100 is not positioned correctly, the gaps (d1, d5) at locations farther from the centerline CL are larger than the gaps (d2, d3, d4) at locations closer to the centerline CL. Hence, even if the connector 230, which is close to the center line CL, is connected correctly (i.e., it adheres tightly) to the corresponding contact 430c, the connectors 210, 250 that are further from the center line CL may not be connected to the corresponding with 41 Oc contacts, 450c. Thus, by placing the contacts 21 Oc, 250c of connectors 210, 250 at the point furthest from the centerline CL, the probability of faulty detection of the assembly of the ink cartridge 100 is reduced. For example, the likelihood that "assembly" will be detected incorrectly when the ink cartridge 100 is incorrectly positioned and thus incorrectly mounted is reduced. Sensor connectors 210, 250 can perform a function that allows the printer control unit (main control circuit 40 and carriage circuit 500) to detect whether the ink cartridge 100 is correctly mounted in the printer 1000 or to detect whether the connectors on the circuit board are properly connected, thereby sensor connectors 210, 250 can be called cartridge assembly detection connectors.

[0106] Because the contact 230c on the power connector 230 is between the two 21 Oc contacts 250c for detecting assembly, after confirming the detection of the assembly there is a high probability that the electrical connection of the power connector 230 is also achieved. Therefore, the probability of a faulty connection on the power connector 230 is lower, and the likelihood of problems arising when using electrical connections is also reduced.

[0107] Sensor connectors 210, 250 are designed to receive higher voltage (higher voltage supplied) than other connectors 220-240, 260 and 270 (FIG. 3). In a situation where the contacts 21 Oc, 250c on connectors 210, 250 are located furthest from the center line CL, their contacts 21 Oc, 250c are at the ends, thus reducing the number of other contacts located near contacts 210c, 250c. Hence, the probability that contact elements 410, 450 designed for high voltage transmission will come into random contact with other connectors (e.g.

VP / 2126 / AW

3162 316 656Β1 with connectors connected to memory module 203). This type of accidental contact can occur during assembly (or disassembly) of the ink cartridge 100. Ink or dust adhering to the circuit board 200 can also cause accidental contact.

[0108] It is not required that the series of contacts 21 Oc to 270c are in the same plane, therefore they can be arranged more or less in the same plane.

B6. Feature 6:

[0109] An additional feature of the present embodiment is that the line that includes the 21 Oc, 250c contacts on the sensor connectors 210, 250 (first line L1) is the longest of a series of lines (FIG. 10C). In this case, the length of the line refers to the section between the two furthest spaced contacts at the two opposite ends of the line. In FIG. 10C example is the distance of line L1 and line L2.

[0110] This feature means that the distance between the contacts 210c, 250c and sensor connectors 210, 250 is greater than the distance between the two ends of other lines. Thus, if the gap on the circuit board 200 (gap between the ink cartridge 100 and the holder 4 (FIG. 4)) is large, the gap between at least one of the two contacts 21 Oc, 250c and the contact mechanism 400 is also large. By placing the 21 Oc, 250c contacts at the two ends of one line it is possible to reduce the number of other contacts near the 21 Oc contact or the number of other contacts near the 250c contact. This feature 6 provides the same effect as feature 5 previously described. More specifically, this reduces the likelihood of a faulty detection of the assembly of the ink cartridge 100. In addition, the likelihood of problems arising when using connector-based electrical connections is also reduced. Moreover, the likelihood that contact elements 410, 450 designed for high voltage transmission will come into random contact with other connectors (e.g. connectors connected to memory module 203) is also reduced.

B7. Feature 7:

[0111] It is possible that during assembly (or disassembly) of the ink cartridge 100, the contact elements (460, 470) of the contacts (260c, 270c) of the second line L2 may contact the connectors on the lead line (first line L1) on the circuit board 200 . Consequently, if the total number of contacts on the line (s) other than the first L1 line is smaller than the total number of contacts on the first L1 line, the probability that the contact element of the printer 1000 will accidentally touch the connectors on the circuit board 200 is reduced. this reduces the likelihood of damage to the circuit board 200. In this case, the total number of other lines may be two or more. In this situation, preferably the total number of contacts on the guide line exceeds the total number of contacts on all other lines.

[0112] As described in the part regarding Feature 1, with reference to FIG. 17A, 17B and 18, the probability of a faulty connection on the leading first L1 line is always lower than on other lines. Hence, by increasing the total number of contacts on

VP / 2126 / AW

ΕΡ2 316 656Β1 first line L1 the overall probability of a faulty connection in a series of contacts is limited.

C. Example 2:

[0113] FIG. 22 and 23 are perspective views of a second embodiment of an ink supply system (printing substance delivery system). It differs from the embodiment shown in FIG. 6A and 6B only in that the elements of the ink cartridge 100, the ink container 130 (forming the whole of the ink supply connector 110 and the ink chamber 120) are separated from the other elements. The configuration of the 1000 printer is the same as the configuration in the method of implementation discussed earlier 1.

[0114] This SI ink supply system includes a body 100A (also referred to as "adapter 100A") and an ink container 100B. The ink container 100B includes a housing 101B for storing ink and an ink supply connector 110. The ink storage chamber 120B is located inside the housing 101B. The ink supply connector 110 is made on the bottom wall 101Bwb (wall in the + Z direction) of the housing 101B. The ink supply connector 110 connects to the ink chamber 120B. The ink supply connector 110 is positioned the same as the ink supply connector 110 discussed above in the ink cartridge 100 (FIGS. 6 to 9).

[0115] The adapter 100A includes a main unit 101A and a printed circuit board 200. The 101 AS space is designed to contain an ink container 100B, located inside the main unit 101 A. In the upper part (in the -Z direction) of the main unit 101A a 101ASop hole that joins the 101 AS space. The main unit 101A also includes a front wall 101Awf and a bottom wall 101Awb. The front wall 101Awf is the wall in the -Y direction, and the bottom wall 101 Awb is the wall in the + Z direction. The front wall 101 Awf connects to the bottom wall 101 Awb (in this embodiment, as a rule, at right angles).

[0116] The front wall 101Awf is positioned the same as the previously discussed front wall 101wf of the ink cartridge 100 (FIGS. 6 to 9). The circuit board 200 is attached to the front wall 101Awf. In addition to the additional hole 101AH, the bottom wall 101Awb is positioned the same as the bottom wall 101wb of the ink cartridge 100 discussed earlier. After placing the ink container 100B in the space 101 AS, the ink supply connector 110 protrudes from the adapter 100A through the opening 101AH. In this embodiment, the opening 101AH is shifted farther toward the mounting direction Z than the series of contacts 21 Oc to 270c from the series of connectors 210 to 270 on the circuit board 200. The opening 101AH is a through hole in the mounting direction Z. The feature of the 101AH hole is that it is located farther in the Z mounting direction than the 21 Oc to 270c contact row (i.e. in the direction of the 100A adapter moving relative to the 1000 printer during assembly) means that with respect to the location parallel to mounting direction Z, the location of hole 101AH is further in the mounting direction Z than the location of the corresponding 21 Oc to 270c contacts.

[0117] FIG. 24 is a cross-sectional view of the adapter 100A and the ink container 100B mounted in

P2 / 2126 / AW

ΕΡ 2 316 656 Β1 handle 4. This section is a simplified version of the section similar to FIG. 9. As with the 100 ink cartridge, the 100A adapter is mounted in the holder 4 by moving it in the Z mounting direction. The 100B ink container is also mounted in the holder 4 by moving it in the Z mounting direction. The 100B ink container is placed in the 100A adapter and in this condition it mounts in the holder 4.

[0118] The opening 101 AH in adapter 100A is designed to face the ink supply nozzle 6 when the adapter 100A is mounted in the holder 4. This means that when the adapter 100A is mounted in the holder 4, the ink supply nozzle 6 is directed towards hole 101AH. During the assembly of the adapter 100A in the holder 4, the outlet of the ink supply nozzle 6 can pass completely through the opening 101AH. When the adapter 100A is mounted in the holder 4, the outlet of the ink supply nozzle 6 may also be in front of the opening 101AH. In either case, the ink supply nozzle 6 is introduced into the ink supply connector 110, which projects from the opening 101AH in the + Z direction.

[0119] In the present embodiment, the sensor 104 (FIG. 3) is omitted, and a capacitor located on the circuit board is connected to the sensor connectors 210, 250 instead. The capacitor detects the mounting of the 100A adapter in a manner similar to the procedure described in FIG. 14 for cartridge detection circuit 503a.

[0120] In the present embodiment, as in the example of the ink cartridge 100 discussed above, the ink container 100B can swing around the ink delivery connector 110. In this case, the adapter 100A also contacts the ink container 100B and can swing around the connector ink supply 110. Hence, also in the SI ink supply system provided in the present embodiment, there may be problems similar to those present in the above-mentioned ink cartridges 100. Thus, in the present embodiment the adapter 100A has the same features as the ink cartridge 100 discussed above (except bypassing ink chamber 120B and ink supply connector 110). This means that the 100A adapter has the same features as the ink cartridge 100 discussed above (e.g., Features 1 to 7). As a result, the SI ink supply system falling within the scope of this embodiment provides a number of advantages comparable to those provided by the above-described ink cartridges 100.

[0121] Once mounted in the holder 4, the position of the adapter 100A defines (limits) the ink container 100B. More specifically, it can be said that the 100A adapter is supported by the 100B ink container. After mounting it in the holder 4, it is not necessary to replace the 100A adapter. If the ink in the ink cartridge runs out, the ink tank can be replaced by removing the empty 100B ink tank without disconnecting the 100A adapter and installing a new ink tank filled with ink.

[0122] In this embodiment, the features 1 to 7 discussed above change as follows. Specifically, the spatial relationships between the connectors (contacts) and the center axis (center line CL) of the ink supply nozzle 6 with the 100A adapter mounted without spaces (correctly) in the 1000 printer have been adopted instead

VP / 2126 / AW

3162 316 656Β1 spatial dependencies between connectors (contacts) on the printed circuit board 200 and the central axis (center line CL) of the ink supply connector 110. The fact that the first line L1 lies close to the 101AH opening means that after installing 1000 the 100A adapter in the printer and the container 100B ink The first L1 line is near the 110op opening of the ink supply connector 110. In this embodiment, it can also be said that if the 100A adapter is correctly installed (with no spaces) in the 1000 printer, the line among the series of lines (contact lines) closest to the ink supply nozzle 6 is the first line L1.

D. Example 3:

[0123] FIG. 25 and 26 are perspective views of a third embodiment of an ink supply system (printing substance delivery system). A fundamental difference from the embodiment shown in FIG. 22 and 23 is that the wall in the X direction (wall perpendicular to the X direction) of the adapter 100Aa (body 100Aa) has been eliminated from the configuration. The main unit 101Aa of the 100Aa adapter includes a 101Aawf front wall, 101Aawb bottom wall and 101Aawbk rear wall. Other features of the Sla ink supply system are similar to the features of the SI ink supply system shown in FIG. 22 and 23. In FIG. 25 and 26 elements identical to the elements included in the SI ink supply system (FIGS. 22, 23) were assigned the same symbols. The circuit board 200 is attached to the front wall 101Aawf.

[0124] On the inside of the front wall 101Aawf (side facing the 100Ba ink container) of the 100Aa adapter, the first RL1 rail is placed, which runs in parallel in the Z mounting direction. The first cut G1, which corresponds to the first RL1 rail, is located on the front wall of 101Bawf 100Ba ink cartridge. On the inside of the rear wall 101Aawbk (side facing the 100Ba ink container) of the 100Aa adapter, a second RL2 rail is placed, which runs parallel to the Z mounting direction. A second G2 notch, which corresponds to the second RL2 rail, is located on the rear wall 101Bawbk of the ink container 100B. The 100Ba ink cartridge is mounted on the 100Aa adapter by inserting the first RL1 rail into the first G1 notch and by inserting the second RL2 rail into the second G2 notch. In this state, the ink supply connector 110 of the ink container 100Ba passes through the opening 101AaH in the bottom wall 101Aawb of the adapter 100Aa and protrudes from the adapter 100Aa (invisible).

[0125] The Sla ink supply system is mounted in the holder 4 in the same manner as the SI ink supply system shown in FIG. 24. Likewise, in the present embodiment, the adapter 100Aa may contact the ink container 100Ba and may swing around the ink supply connector 110. Hence, also in the Sla ink supply system provided in the present embodiment, there may be problems similar to those in the embodiments discussed above. On the other hand, the Sla ink supply system shown in the present embodiment has features (e.g., Features 1 to 7) comparable to those previously discussed with respect to the SI ink supply system. As a result, the Sla ink supply system enters

VP / 2126 / AW

The scope of the present embodiment provides a number of advantages comparable to those of the SI ink supply system discussed above.

E. Example 4:

[0126] FIG. 27 is an illustration depicting a fourth embodiment of an ink supply system (printing material supply system). The difference from the Sla ink supply system shown in FIG. 25 and 26 is to eliminate the back wall of 101Bawbk. Other features of the Slb ink supply system are identical to the features of the Sla ink supply system shown in FIG. 25 and 26. In FIG. 27 is a cross-sectional view similar to that shown in FIG. 24. The 101 Ab main unit of the 100Ab adapter (100Ab body) has a 101Aawf front wall and a 101Aawb bottom wall. The 100Ab adapter can come into contact with the 100Ba ink container and can swing around the ink supply connector 110. The Slb ink supply system has features (e.g., Features 1 to 7) comparable to those previously discussed for the SI ink supply system. As a result, the Slb ink supply system falling within the scope of this embodiment provides a number of advantages comparable to those provided by the SI ink supply system discussed above.

F. Embodiment 5:

[0127] FIG. 28 is an illustration depicting a fifth embodiment of the ink supply system (printing material supply system). The difference from the Slb ink supply system shown in FIG. 27 is to eliminate the back wall 101Aawb. Other features of the Sic ink supply system are identical to those of the Slb ink supply system. In FIG. 28 is a cross-sectional view similar to that shown in FIG. 27. The 101 Ac main unit of the 100Ac adapter (100Ac body) is equipped with a 101Aawf front wall. The 100Ac adapter can come into contact with the 100Ba ink container and can swing around the ink supply connector 110. The Sic ink supply system has features (e.g., Features 1 to 7) comparable to those previously discussed for the SI ink supply system. As a result, the Sic ink supply system falling within the scope of this embodiment provides a number of advantages comparable to those provided by the SI ink supply system discussed above. In this embodiment, the 100AC adapter is mounted in the 100Ba ink container during operation. You can use any number of elements that make up this configuration. For example, the 100Ba ink container can be equipped with protruding elements, and the 100Ac adapter can be equipped with recesses so that the 100Ac adapter can be mounted in the 100Ba ink container by introducing protruding elements into the recesses.

G. Example 6:

VP / 2126 / AW

ΕΡ 2 316 656 Β1 [0128] FIG. 29 is an illustration depicting a sixth embodiment of an ink supply system (printing material supply system). The difference from the one shown in FIG. 28 of the Sic ink supply system consists in the fact that the ink container is equipped with a memory module 203, and not with a printed circuit board and with conductive paths connecting the memory module 203 with connectors located on the printed circuit board. Other features of the Sld ink supply system are identical to those of the Sic ink supply system. In FIG. 29 shows a cross-section comparable to FIG. 28 and an enlarged view of the area surrounding the 200d circuit board. The main unit 101 Ad of the 100Ad adapter (body 100Ad) is equipped with a 101Adwf front wall. The 200d printed circuit board is attached to the front wall 101Adwf. Memory module 203 is attached to the 100Bd ink container. In FIG. 29 elements identical to those included in the Sic ink supply system shown in FIG. 28 assigned the same symbols.

[0129] The circuit board 200d is equipped with a board 205 and a series of connectors located on the board 205. The series of connectors is identical to the connectors 210 to 270 shown in FIG. 10C. In the figure, the power connector 220 and reset connector 260 are marked for reference. An E2c conductive path is connected to the power connector 220. Conductive path E2c passes through plate 205 and front wall 101Adwf of the 100Ad adapter. The conductive path E2c extends in the + Y direction from the power connector 220 and leads to the connector E2a. The E2a connector is exposed on the inside of the front wall 101 Adwf (side facing the 100Bd ink cartridge). A similarly constructed E6c conductor is also connected to reset connector 260. Similar conductive (invisible) paths are also connected to other connectors (connectors 230, 240, 270) of memory module 203. The construction of the front wall 101 Adwf is the same as the construction of the front wall 101 Aawf shown in FIG. 28, except that holes are placed on it to allow conducting paths E2c, E6c.

[0130] A plate 203s is attached to the front wall 101Bdwf of the 100Bd ink container. Memory module 203 is attached to the back of the 203s board (side facing the front wall 101Bdwf). On the opposite side of the 203s board (side facing towards the 100Ad adapter) there are a number of connectors. In FIG. 29 illustratively shows two connectors E2b, E6b. A series of connectors located on the 203s board are connected to the corresponding array of fields (FIG. 3: Pvdd to Pvss) of memory module 203. The Pvdd power field is connected to the E2b connector and the Prst reset field is connected to the E6b connector. The E2b connector is toward the E2a connector. The E6b connector is toward the E6a connector.

[0131] After the Sld ink supply system has been correctly installed in the holder 4 when the 100Ad adapter is mounted (or contacts) the 100Bd ink container in the correct position, connector E6a contacts connector E6b and connector E2a contacts connector E2b . In this way, the Prst reset field connects to the reset connector 260, and the Pvdd power field connects to the power connector 220. The other field connections of memory module 203 and board connectors 205, which are omitted in the drawing, are connected in a similar way. In this way the printer

VP / 2126 / AW

ΕΡ2 316 656Β1

1000 can access memory module 203 via board connectors 205.

[0132] The Sld ink supply system shown in the current embodiment has features (e.g., Features 1 to 7) comparable to those previously discussed with respect to the Sic ink supply system shown in FIG. 28. Consequently, the Sld ink supply system provides a number of advantages comparable to those provided by the Sic ink supply system.

[0133] The feature of the present embodiment (i.e., attachment of the memory module 203 to the 100Bd ink container instead of the 200d circuit board) is not limited to the Sic ink supply system shown in FIG. 28 and can be implemented analogously to those shown in FIG. 22 to 27 ink supply systems SI, Sla, Slb. As a general rule, various configurations are used involving a board with a series of connectors located on the board, changing the arrangement of the components on the printed circuit board equipped with the connectors used to establish connection with contact elements 410 to 470 of the printer 1000 (FIG. 11). In this case, the connectors include connectors for electrical connection to the memory module 203.

H. Example 7:

[0134] FIG. 30 is an illustration of a seventh embodiment of the 1000K printer. The difference from the printer 1000 shown in FIG. 1 is that 4K holders adapted to connect 100K ink cartridges are attached to the 1000K printer housing instead of the printhead carriage (invisible). 4K handles and printhead are connected with invisible tubes. The ink from each 100K ink cartridge is fed to the print head via a tube.

[0135] FIG. 31 is a perspective view of a 100K ink cartridge. The 100K ink cartridge includes a 101K housing, 200 circuit board and 11 OK ink supply connector. The 101K enclosure includes a 101Kwf front wall and a 101Kwb bottom wall. The 101Kwf front wall connects to the 101Kwb bottom wall (in this embodiment, as a rule, at a right angle). There is a 101P ink cartridge inside the 101K housing.

[0136] The circuit board 200 is identical to the circuit board 200 shown in each of the previous embodiments. The circuit board 200 is attached to the front wall 101 Kwf of the 101K housing. On the front wall 101Kwf, the outline of the circuit board fastening elements 200 (e.g., protruding elements P1, P2) are the same as on the front wall 101wf in the embodiment discussed above (FIG. 6A).

[0137] The features of the ink supply connector 11 OK are the same as the features of the ink supply connector 110 in each of the previous embodiments. The 11 OK ink supply connector is located on the bottom wall of the 101Kwb 101K housing. The 110K ink supply connector connects to the 101P ink cartridge.

[0138] In addition, positioning holes 127, 128 and compression hole 17 are provided on the bottom wall 101 Kwb. Pressure can be applied to the 101P ink cartridge by feeding it

VP / 2126 / AW

ΕΡ 2 316 656 Β1 air through the compression hole 17. Compression is carried out to improve the ink supply.

[0139] FIG. 32 is a perspective view of 4K handles. In this embodiment, each 100K ink cartridge is equipped with a handle 4. Each 4K handle includes a 102K movable support, a 400K contact mechanism , a 6K ink supply nozzle, 103Ka, 103Kb projecting positioning elements, and a 108K rotary lever. The movable support 102K supports the 100K ink cartridge resting on the bottom wall of the 101Kwb (FIG. 31) 100K ink cartridge. The projecting positioning elements 103Ka, 103Kb are attached to the movable support 102K. The projecting positioning elements 103Ka, 103Kb protrude in the -Z direction and enter into the corresponding positioning holes 127, 128 of the 100K ink cartridge. The 400K contact mechanism is attached to the 102K movable support in the forward direction (-Y direction). The 400K contact mechanism has the same features as the previously discussed contact mechanisms 400 (FIG. 11). Although this element is not shown in the drawing, a similar circuit to the carriage 500 is connected to each of the contact mechanisms 400 (FIG. 3).

[0140] In the present embodiment, the 100K ink cartridge is mounted in the 4K holder by moving the 100K ink cartridge in the Z mounting direction. In this case, moving the 100K ink cartridge in the direction of the movable support 102K causes the movable support 102K to move in the + Z direction. The second 4K handle (4Ka) shown in FIG. 32 shown in the condition prior to installing the 100K ink cartridge. The third 4K handle (4Kb) is shown in the condition after installing the 100K ink cartridge (the 100K ink cartridge itself is not shown in the illustration). In this case, the position of the 102K movable support shown at the 4Kb handle will also be referred to as "the position after assembly". Movement of the 102K movable support in the + Z direction causes the 6K ink supply nozzle to appear in the -Z direction relative to the 102K movable support. The ink supply nozzle 6 then enters the ink supply connector 11 OK (FIG. 31) of the 100K ink cartridge.

[0141] When assembling the 100K ink cartridge, the 100K ink cartridge (movable support 102K) is pushed until it reaches a position further from the position after assembly (position shifted in the + Z direction). In this way, the 112K mandrel at the top of the 108K rotary lever connects to the connection element (invisible) of the 100K ink cartridge. The 100K ink cartridge (102K movable support) stops in position after assembly. If the 100K cartridge (102K movable support) is pressed further out of position after assembly, the 112K spindle will disengage. The 100K ink cartridge then slides out of the 4K holder. The 108K rotary lever and connecting element may also have other features.

[0142] The 100K ink cartridge included in the present embodiment, such as the 100 ink cartridge described in Embodiment 1, can swing around the ink supply connector 11 OK. Hence, in the present embodiment, problems similar to those known from the ink cartridges 100 described in Embodiment 1 may also arise. Thus, in the present embodiment, the 100K ink cartridge is equipped with a printed circuit board 200 and an 11 OK ink supply connector similar to that provided on the above-described ink cartridge 100. Features of the printed circuit board 200

VP / 2126 / AW

ΕΡ 2 316 656 Β1 and the 110K ink supply connector are the same as the features of the circuit board 200 and the ink supply connector 110 of Embodiment 1, respectively. The first line L1 (FIG. 10C) on the circuit board 200 is closer to the hole of the ink supply connector 11 OK than the second line. This means that the 100K ink cartridge has the same features as the ink cartridge 100 of Embodiment 1 (e.g., Features 1 to 7). As a result, the 100K ink cartridge falling within the scope of this embodiment provides a number of advantages comparable to those provided by the ink cartridge 100 of Embodiment 1.

I. Modified examples of the printed circuit board:

[0143] FIG. 33 is an illustration depicting another embodiment of the circuit board. The difference from the circuit board 200 shown in FIG. 10C consists in the fact that seven 210G to 270G connectors are positioned in such a way that they form a single line extending in the X direction. Compared to connectors 210 to 270 of Example 1, the 210G to 270G connectors are arranged in a rectangular outline, extended towards Z. The location of 210Gc to 270Gc contacts belonging to 210G to 270G connectors is identical to the location of 21 Oc to 270c contacts in Example 1. Therefore, the benefits mentioned above can be achieved even if the 210G to 270G connectors on the 200G printed circuit board are used instead of connectors 210 to 270 on the 200, 200d printed circuit boards shown in the previous embodiments.

[0144] FIG. 34 is an illustration depicting another embodiment of the circuit board. The difference from that shown in FIG. 10C of the printed circuit board 200 relies on irregular shape of the 21 OH to 270H connectors. Also in this embodiment, the arrangement of the 210Hc to 270Hc contacts associated with the 21 OH to 270H connectors is identical to the arrangement of the 21 Oc to 270c contacts in Embodiment 1. Hence, the benefits mentioned above can be achieved even if the 21 OH to 270H connectors on the 200H printed circuit board are used instead of the 210 to 270 connectors on the 200, 200d printed circuit boards shown in the previous embodiments.

[0145] FIG. 35 is an illustration depicting another embodiment of the circuit board. The difference from that shown in FIG. 10C of the printed circuit board 200 relies on the irregular shape of the 21 OJ to 270J connectors. Similarly, the 200J printed circuit board is different from the 200, 200G printed boards discussed above, the difference being the difference in the shape of the 21 OJ to 270J connectors, which was determined so that a number of connectors are superimposed when viewed in the Z mounting direction (from -Z to + FROM). Also in this embodiment, the arrangement of the 210Jc to 270Jc contacts belonging to the 21 OJ to 270J connectors is identical to the 21 Oc to 270c contact arrangement in Example 1. Therefore, the benefits mentioned above can be achieved even if the 21 OJ to 270J connectors on the board 200J printed circuit board will be used instead of connectors 210 to 270 on the 200, 200d circuit boards shown in the previous embodiments.

[0146] FIG. 36 is an illustration depicting another embodiment of the circuit board. The five connectors 21 OK to 250K include conductive elements in the shape of a line extending in the -Z direction in addition to the conductive parts identical to those present in those indicated in FIG. 10C connectors 210

VP / 2126 / AW

3162 316 656Β1 to 250. Two connectors 260K, 270K include conductive elements in the shape of a line extending in the + Z direction in addition to the conductive parts identical to those present in those indicated in FIG. 10C connectors 260 to 270. Also in the present embodiment, the arrangement of the 210Kc to 270Kc contacts belonging to the 21 OK to 270K connectors is identical to the arrangement of the 21 Oc to 270c contacts in Example 1. Hence, the benefits mentioned above can be achieved even if the 21 OK to 270K connectors on the 200K printed circuit board are used instead of the 210 to 270 connectors on the 200, 200d printed circuit boards shown in the previous embodiments.

J. Modified embodiments:

[0147] Among the components described in the previous embodiments, elements other than those covered by the independent claims are additional elements that may be omitted if desired. The invention is not limited to the particular embodiments listed above, if it is in accordance with the scope and general principle set forth therein, it may be put into practical use in various ways, for example as shown in the modified examples below.

Modified embodiment 1:

[0148] Pin 220c of the power connector 220c included in the embodiment shown in FIG. 21 may be in a position that coincides with the center line CL. The circuit board 200 as a whole can also be placed so that it does not overlap the center line CL. Some of the contacts can be placed so that they overlap with other contacts when viewed in the Z mounting direction (from -Z towards + Z).

[0149] Regardless of the situation, it is preferable to place the contacts belonging to the power connectors on the guide line (first line L1). This reduces the likelihood of a faulty power connector connection, thus reducing the likelihood of problems encountered when using a connector-based electrical connection.

Modified embodiment 2:

[0150] It is possible to use various other components as components mounted on 100, 100K ink cartridges and 100A, 100Aa, 100Ab, 100Ac, 100Ad adapters in the above described embodiments. For example, the sensor 104 may be used to apply voltage to the ink contained in the ink cartridge 100 and to measure resistance. You can specify ink parameters and level based on the resistance value. The devices used to detect the assembly of 100, 100K ink cartridges and 100A, 100Aa, 100Ab, 100Ac, 100Ad adapters are not limited to piezoelectric elements and various other elements. Instead of piezoelectric elements can be used on

PZ / 2126 / AW 36 ΕΡ2 316 656Β1 example capacitors. You can also use a conductive path that will connect (short) two connectors. If a conductive path is used, the assembly can be detected by checking the electrical conductivity between the two connectors. Furthermore, the device used to detect assembly may be a separate device from the sensor used to detect ink level (in this case, additional connectors would be provided for the purposes of the additional device). In the above described embodiments, the ink level detection sensor can be omitted.

[0151] The configurations of the memory module 203 are not limited to those shown in FIG. 15, various other configurations are possible. For example, if the memory module 203 includes a parasitic diode, it is possible to omit the protection diode, which is the equivalent circuit for the parasitic diode. Because the memory module 203 mounted in this case can be used as a series connected memory, adapted to receive commands and memory addresses via a data signal line from an external device (e.g. control unit (all main control circuit 40 and carriage circuit 500) of the printer 1000 in FIG .3) instead of generating memory addresses based on a clock signal. Instead of a series of memory modules connected to the printer control unit via the bus, a series of memory modules can be connected to the printer control unit individually. In this case, instead of the reset signal, the printer control unit can send an integrated circuit selection signal to the selected memory module to control the reset state and the operating state through the level of the integrated circuit selection signal. Operation of this type of memory (i.e. internal counter values ​​and memory register) is reset based on the changes made to the integrated circuit selection signal. Therefore, the IC selection signal is the same as the "reset signal". The reset field provided in the memory modules described in the previous embodiments can be omitted, and the functions of the memory modules of the embodiments discussed above, implemented by the memory module through changes in the level of the reset signal, can be implemented based on changes in the level of control voltage provided by the power field. In this case, the memory module responds to the supplied power potential, and the memory module resets when the power potential is interrupted. Furthermore, various devices can be used to transmit and / or receive data signals, not just the memory module 203. For example, memory that does not allow updating of data (e.g. ROM) can be used. This type of memory can also store information about the types of inks. Built-in memory including CPU and memory can also be used. This enables flexible control based on the CPU's data processing algorithm. Regardless of the circumstances, any of the plurality of devices that are adapted to operate in response to the power potential supplied by the printing substance consuming device (e.g., printer 100 of FIG. 3) may be used as the devices described herein. If this type of device is used in response to the power supply potential supplied to it, interruption of the power supply potential supply may cause serious problems (e.g. failure). Therefore, it is an advantageous solution for the contact receiving the power supply potential to be located on the guide line.

VP / 2126 / AW

3162 316 656Β1 [0152] The devices can be arranged according to a number of different arrangement schemes. For example, memory module 203 (FIG. 3) can be attached directly to another component other than the board (e.g., housing 101 shown in FIG. 6, main unit 101A shown in FIG. 22 or housing 101K shown in FIG. 31).

[0153] An arbitrary number of connectors can be selected for the total number of connectors, depending on which devices are used. A series of contacts can be placed so that they form three or more straight lines. Lines other than the guide line may include a line or lines including the total number of contacts above that provided on the guide line. Regardless of the situation, if a series of contacts are arranged on several lines, the distance between the center line CL and the contacts may be short, as shown in FIG. 21. In this way, the distance between the contacts is limited.

Modified embodiment 3:

[0154] The features of the ink supply systems described in the previous embodiments are not limited to the features shown in FIG. 6 to 9, FIG. 22 to 23, FIG. 25 to 26 and FIG. 27, 28, 29 and 31, it is possible to use various other features. For example, a single ink cartridge may be equipped with a number of ink containers (sets consisting of an ink chamber and an ink supply connector).

[0155] At least some of the series of connectors may be placed directly on a non-wafer member (e.g., on the front wall 101wf in FIG. 6, front wall 101Awf in FIG. 22 or the front wall 101Kwf in FIG. 31). Moreover, the feature of "arrangement of connectors on the front wall" is not limited to cases where connectors are formed directly on the front wall, and may also relate to cases where these connectors are formed on a plate attached to the front wall.

[0156] Furthermore, a number of different features may be used, wherein the printed circuit board providing electrical connection to the printing substance consuming device (e.g., the printer 1000 shown in FIG. 3) must be mounted (connected to) onto the printing material consuming device. For example, the circuit board can be attached to the ink cartridge as in the embodiment shown in FIG. 6A or FIG. 31. The circuit board can also be attached to the body (adapter) as shown in the embodiment in FIG. 22 to 29. In this case, various features can be used as the body (adapter) features. For example, a feature may be used that allows the independent assembly of the print media consuming device as shown in the embodiment of FIG. 22 to 27. Alternatively, as shown in the embodiment shown in FIG. 28 and 29, use a body attached to the print material container (e.g., the 100Ba ink container shown in FIG. 28), and the body, together with the print material container attached thereto, can be attached to the print media consuming device. In any case, if the position of the body determines (limits) the container of printing material, i.e. if the movement of the print material container means that the body needs to move with it, the body can be supported on the material container

EP 2 316 656 -1 print.

Modified embodiment 4:

[0157] The total number of ink cartridges that the printer can use simultaneously is not limited to six - another number (e.g., one, four or eight) may be used. You can also use different types of ink. For example, you can use gray ink that is lighter than black. You can also use colored inks (e.g. red or blue). You can also use inks without pigments (e.g. colorless transparent ink containing a substance that protects the ink droplets).

[0158] The printing substances described in the previous embodiments are not limited to ink, other printing substances may be used. For example, you can use toner. Furthermore, a printing substance-consuming device need not be limited to a printer, a number of other printing-material consuming devices can be used.

Modified embodiment 5:

[0159] Some of the equipment components used in the above-described embodiments can be replaced by programming elements, and in the same way all the elements implemented in the above configurations by means of software can be implemented by means of equipment. For example, the function of the M20 ink level detection module shown in FIG. 3 can be implemented by a hardware circuit equipped with a logic circuit.

[0160] In addition, in cases where some or all of the functions of the inventions are implemented at the software level, the software (computer program) may be provided in a form stored on a computer-readable medium. For the purposes of the present invention, the term "computer-readable media" is not limited to portable media such as floppy disks or CD-ROMs, but also includes internal data storage media such as various types of RAM and ROM as well as external storage media, such as a hard disk connected to a computer.
