The present invention relates to a container holder of a liquid consuming device in which a liquid storage container including a pressure chamber into which a pressurized fluid is introduced and a liquid storage chamber in which a liquid is stored is detachably mounted.
Typical examples of a liquid consuming device that injects droplets from a liquid injection head include an inkjet recording device provided with an inkjet recording head for image recording, and a color material injection head used for manufacturing a color filter such as a liquid crystal display. Equipment, organic EL display, equipment equipped with an electrode material (conductive paste) injection head used for electrode formation such as surface emitting display (FED), equipment equipped with a bioorganic material injection head used for biochip manufacturing, precision pipette And the like equipped with a sample injection head.
Among these, the inkjet recording device is used for many printing including color printing in recent years because the noise during printing is relatively low and small dots can be formed at a high density. As a liquid supply method for an inkjet recording device, there is a so-called cartridge method in which a liquid is supplied from a liquid storage container in which the liquid is stored to a liquid consumption device. In this cartridge system, the liquid storage container is easily attached to and detached from the liquid consumption device so that the user can replace the liquid storage container when the liquid in the liquid storage container is consumed.
Further, some liquid storage containers of this type are provided with a circuit board on the outer surface on which a storage element (IC) for storing information such as the type of ink and the remaining amount of ink is mounted. In this case, the container holder of the liquid consuming device that houses the liquid containing container is provided with a device-side terminal of the liquid consuming device connected to the contact of the circuit board. When mounting the liquid storage container provided with such a circuit board on the container holder, it is necessary to securely connect the contacts of the circuit board and the device-side terminals of the liquid consuming device. That is, it is necessary to suppress the deviation between the terminal on the device side and the contact on the circuit board side within a conductive range.
In the conventional liquid storage container and container holder, as a mechanism for securely fixing the liquid storage container in a predetermined position of the container holder, for example, in cooperation with the device-side fixing structure provided in the container holder, the container Some have a container-side fixed structure that regulates the movement of the container in the pull-out direction so that it can be released (see, for example, Patent Document 1).
This container-side fixing structure is a locking pin (covered) of the device-side fixing structure provided on the container mounting portion in a state where the container is mounted on the container mounting portion against the urging force in the direction opposite to the insertion direction. It has a guide groove that regulates the movement of the container in the direction opposite to the insertion direction in cooperation with the locking member).
Therefore, when fixing the liquid storage container to the container holder, the container is inserted into the container mounting portion, and the pressing force is applied after further pushing the container against the urging force in the direction opposite to the insertion direction by the slider member. When released, the locking pin of the device-side fixing structure moves to the locking position of the guide groove, and the liquid storage container is fixed. When removing the liquid storage container from the container holder, the locking pin is moved to the non-locking position of the guide groove by pushing the container into the container mounting portion. Therefore, when the pressing force is released, the container is moved by the slider member. It is urged in the direction opposite to the insertion direction and discharged.

<p> The conventional liquid storage container described in Patent Document 1 has attempted to realize a reliable connection between the contact of the circuit board and the contact of the liquid consuming device side by arranging the circuit board in the vicinity of the container-side fixed structure. .. Specifically, a flat, substantially rectangular parallelepiped container is oriented so that a pair of parallel maximum surfaces are perpendicular to the vertical plane, and the maximum surfaces are not overlapped vertically (in the vertical direction) (hereinafter, "" When they were housed side by side in a "flat position"), a circuit board was provided on the side surface, and a container-side fixed structure was arranged on the lower surface in the vicinity thereof. That is, the circuit board and the container-side fixed structure are provided on two adjacent orthogonal surfaces on the outer surface of the container. However, in recent years, as the number of liquid storage containers has increased in order to improve the recording quality, it has come to be assumed that the liquid storage containers can be placed vertically to enable high-density storage.</p><p> However, in the conventional liquid storage container, the circuit board and the container-side fixed structure are arranged on two orthogonal surfaces on the outer surface of the container. Therefore, for example, if the liquid storage container is vertically placed in this structure, the adjacent liquids are stored. It was necessary to interpose a separation space between the containers to secure the device-side fixed structure, and it became impossible to meet the demand for increasing the container storage density. On the other hand, if the device-side fixed structure is simply relocated, the positioning accuracy of the circuit board contact is lowered, the device-side terminal and the circuit board contact are likely to separate from each other, and there is a risk that a good electrical connection state cannot be obtained.</p><p> Further, the liquid storage container described in Patent Document 1 is a closed type liquid storage container. In this closed type liquid storage container, the liquid storage chamber is formed of a flexible bag having a closed structure or the like to prevent deterioration of the liquid due to contact with the atmosphere. Suitable for large-capacity liquid storage containers because the quality can be maintained stably for a long period of time.</p><p> However, since the flexible bag body, which is the liquid storage chamber, is pressurized from the outside, when the pressurized fluid is introduced into the pressure chamber, the pair of maximum surfaces parallel to the liquid storage container expands and deforms. As described above, since the circuit board is provided on the side surface of the container, when the container expands and deforms, the pressure contact position of the device-side terminal with respect to the circuit board contact may be displaced, resulting in contact failure. In addition, the expansion and deformation of the container may cause a shift in the fixed position of each liquid storage container with respect to each slot of the container holder.</p><p> As a result, a load is applied to the engaging portion between the device-side fixed structure and the container-side fixed structure, the partition wall of each slot, and the like, and for example, the locking pin, the guide groove, and the partition wall of each slot may be deformed. There is also a problem that a stronger fixing mechanism is required and the manufacturing cost is increased. Therefore, the present invention has been made in view of the above situation, and is a good container holder that can store liquid storage containers at high density without deteriorating the electrical connectivity between the contacts of the device side terminal and the circuit board, and liquid consumption. It is an object of the present invention to provide an apparatus and a liquid storage container.</p>

Support side wall and Achieved by a container holder characterized by:</p><p> According to the container holder having such a configuration, when the liquid storage container is mounted on the container mounting portion, a space is formed by the notch portion at least one of the upper portion or the lower portion between the adjacent containers. Then, a guide protrusion is arranged in this space. Each liquid container is guided in the insertion direction by the guide protrusion and is positioned in the container mounting portion. That is, there is no partition wall that separates the container mounting portions between the adjacent liquid storage containers. Therefore, it is not necessary to arrange a plurality of containers apart from each other by the amount of the partition wall and the guide protrusion. That is, it is possible to store a plurality of liquid storage containers in close proximity (high density). Therefore, it is possible to form a compact container holder in which the total width of the container in the thickness direction is small.</p><p> Further, in the present invention, when the pressurized fluid is introduced into the pressurizing chamber of the liquid containing container, the pair of maximum surfaces parallel to each liquid containing container expands and deforms. Then, in the container holder having no partition wall, at least a part of the maximum surfaces of adjacent containers come into contact with each other and are pressed against each other. Further, of the maximum surfaces of each container at both outer ends, at least a part of the maximum surface that does not face the maximum surface of the other container is in contact with the support side wall of the holder and is pressed against each other.</p><p> That is, when the pressurized fluid is introduced into each container mounted on the holder, the container is in a tight state between the pair of support side walls due to the expansion force of the container itself. Then, a plurality of containers whose expansion and deformation are regulated are firmly and integrally fixed to the container mounting portion. On the other hand, when the pressurization of the pressurizing chamber is released and the expanded container returns to its original shape, there is no pressure contact between adjacent containers or between the container and the support side wall, so that each liquid container can be attached and detached. It can be done smoothly.</p><p> As described above, according to the present invention, since the expansion and deformation of each container is regulated when the liquid container is pressurized, it is possible to prevent the contact between the terminal on the device side and the contact point of the circuit board from being displaced, and these electricity It is possible to prevent deterioration of target connectivity. Further, the load applied to the engaging portion between the device-side fixed structure and the container-side fixed structure can be reduced. Further, since a plurality of containers are firmly and integrally fixed to the container mounting portion by their own expansion force, it is not necessary to provide a partition wall for partitioning the container mounting portions from each other, and the holder can be simplified and miniaturized. Is possible.</p><p> Further, the contact points of the electrodes of the circuit board and the container-side fixed structure are arranged on the first side surface and the second side surface of the container, respectively, so that the maximum surface (third or fourth side surface) of the adjacent container can be arranged. ), Since it is not necessary to dispose the device-side terminal and the device-side fixed structure between each other, it is possible to accommodate a plurality of containers at high density. That is, according to the present invention, it is possible to obtain a simple and compact holder capable of accommodating a plurality of containers at a high density without deteriorating the electrical connectivity between the terminal on the device side and the contact point of the circuit board. ..</p><p> In the container holder with the above configuration<u style="single">,Before</u>Record<u style="single">Liquid containment</u>Maximum surface of the container<u style="single">Is the above</u>On the support<u style="single">It is mounted on the container mounting portion so as to be perpendicular to the container mounting portion.</u>Is desirable.</p><p> According to the container holder having such a configuration, when the container is mounted on the container mounting portion, the guide protrusion is arranged in the lower portion between the adjacent liquid storage containers.

A resin cover 6 is mounted on the sheet film 24 that seals the open surfaces of the bag body accommodating portion 3 and the detection unit accommodating portion 4.
In this embodiment, there are five types of ink cartridges 100. Five different colors of ink are stored in the ink pack 20 of the five types of ink cartridges 100. These five types of ink cartridges 100 differ only in the type of ink stored inside the ink pack 20 and the detailed shape of the identification unit 22 as described above, and the other configurations are the same. ..
As shown in FIGS. 9 and 11, the ink cartridge 100 has a substantially rectangular front end surface 11 and a rear end surface 12 facing the front end surface 11. The front end surface 11 and the rear end surface 12 are surfaces that become the front end and the rear end in the insertion direction, respectively, when the ink cartridge 100 is mounted in the cartridge slots 7A to 7E. Further, as shown in FIGS. 7 to 9, 11 and 12, the ink cartridge 100 has a first short side 13a of a substantially rectangular tip surface 11.<u style="single">At the tip surface 11</u>First side 15 intersecting with, second short side 13b of approximately rectangular tip surface 11<u style="single">At the tip surface 11</u>Second side 25 intersecting with, first long side 14a of approximately rectangular tip surface 11<u style="single">At the tip surface 11</u>Third side 35a intersecting with, second long side 14b of approximately rectangular tip surface 11<u style="single">At the tip surface 11</u>It has a fourth side 35b that intersects with.
As shown in FIGS. 7, 8 and 11, the ink cartridge 100 is vertically installed in the cartridge slots 7A to 7E. The ink cartridge 100 is mounted in the cartridge slots 7A to 7E so that the first side surface 15 is on the upper side and the second side surface 25 is on the lower side. Further, the ink cartridge 100 is placed on the substrate 241 in parallel with the third side surface 35a and the fourth side surface 35b facing each other in a direction parallel to the vertical plane. As shown in FIG. 7, one of the pair of support side walls 262 of the cartridge holder 200 faces the third side surface 35a of the ink cartridge 100 at both outer ends. Further, the other support side wall 262 faces the other fourth side surface 35a of the ink cartridges 100 at both outer ends.
As shown in FIGS. 9 and 15, the tip surface 11 is provided with an ink supply port 7 and an air inlet 9. The ink supply port 7 is connected to the ink ejection port 20a of the ink pack 20 (see FIG. 10). The ink ejection port 20a is located near the center of the tip surface of the ink pack 20. That is, when the ink cartridge 100 is mounted in the cartridge slots 7A to 7E, the ink supply port 7 is arranged so as to be offset above the center in the height direction (vertical direction) of the ink pack. A flow path 19 connecting the ink supply port 7 and the ink discharge port 20a is provided. When the ink cartridge 100 is not installed in the cartridge slots 7A to 7E, the ink supply port 7 is blocked by a valve or a seal. At this time, a pressure (static pressure) is applied to the ink supply port 7 so that the ink filled in the ink pack 20 tries to go out from the ink supply port 7. Since the static pressure is higher as the amount of ink in the ink pack 20 is larger, the static pressure (initial static pressure) in the initial state in which the ink is sufficiently filled is higher. If the ink supply port 7 is opened while the static pressure in the ink pack is relatively high, ink may leak from the ink supply port 7. However, if the ink supply port 7 is located above the center of the ink pack 20 in the height direction (vertical direction) as in the present embodiment, the ink supply port 7 is located in the ink pack 20 at the position. The static pressure of the ink becomes low, and the static pressure acting on the ink supply port 7 can be reduced by the action of the flow path resistance caused by the flow path 19 connecting the ink supply port 7 and the ink ejection port 20a. is there. That is, according to the present embodiment, even when the ink cartridge 100 is mounted in the cartridge slots 7A to 7E, when the ink supply pin 249 is inserted into the ink supply port 7, ink is unlikely to leak from the ink supply port 7.
Here, the supply of ink from the ink pack 20 to the recording head 225 will be described with reference to FIGS. 1, 4, 5, and 9 to 12. When the ink cartridge 100 is installed in the cartridge slots 7A to E, the ink supply pin 249 described above is inserted into the ink supply port 7. The ink supply pin 249 is connected to the recording head 225 via the ink supply path 223 and the valve unit 224.
Further, when the ink cartridge 100 is installed in the cartridge slots 7A to E, the air inlet 9 is inserted into the air contact port 248 described above. The air communication port 248 is connected to the pressurizing pump 226 via the pressurized air supply path 227. The pressurizing pump 226 can pressurize the ink pack 20 by supplying pressurized air to the bag body accommodating portion 3 through the pressurized air supply path 227, the air communication port 248, and the air inlet 9. .. When the ink pack 20 is pressurized in this way, the ink flowing out from the ejection port 20a of the ink pack 20 is supplied to the recording head 225 of the inkjet recording device 211 via the ink supply port 7.
As shown in FIGS. 9 and 12, the tip surface 11 of the ink cartridge 100 is provided with a pair of positioning holes 21 and 23 separated from each other. The functions of the positioning holes 21, 23 and the pair of positioning pins 247, 247 described above will be described with reference to FIGS. 4, 5, 9, and 11.
When the ink cartridge 100 is inserted into the cartridge slots 7A to 7E, the tips of the positioning pins 247 and 247 are fitted into the positioning holes 21 and 23. After that, when the ink cartridge 100 is further inserted into the inner side of the cartridge slots 7A to 7E, the ink cartridge 100 moves with reference to the positioning pin 247.
When the ink cartridge 100 is completely installed in the cartridge slots 7A to 7E, the positioning holes 21, 23 are fitted with the pair of positioning pins 247, 247 to determine the position of the ink cartridge 100 in the direction along the tip surface 11. Therefore, the movement of the cartridge 100 in the direction along the tip surface 11 is restricted. As shown in FIG. 11, the pair of positioning holes 21 and 23, the circuit board 17 described later, and the container-side fixed structure 40 are arranged on substantially the same vertical cross section AA (see FIG. 8).
As can be seen from FIGS. 9 and 12, in the present embodiment, one positioning hole 21 is set to a round hole having a shape substantially corresponding to the cross-sectional shape perpendicular to the axial direction of the positioning pin 247, and the other positioning hole 21 is positioned. The hole 23 is set as an elongated hole elongated in the height direction of the case 5 (in the direction of arrow H in FIGS. 9 and 12, that is, in the vertical direction). By forming one of the positioning holes 23 into an elongated hole in this way, it becomes easy to allow dimensional tolerances and the like while maintaining positioning accuracy.
That is, when the cartridge 100 is mounted in the cartridge slots 7A to 7E, the positioning accuracy of the cartridge 100 in the cartridge slots 7A to 7E is maintained in the upper positioning hole 21, and the positioning hole 23 and the positioning pin 247 due to dimensional tolerance or the like are maintained. The relative misalignment with (see FIG. 4) is absorbed by the lower positioning hole 23. The ink outlet 7 is provided in the vicinity of the upper positioning hole 21 that maintains the positioning accuracy. Therefore, the ink outlet 7 and the ink supply pin 249 (see FIG. 4) are accurately positioned.
As shown in FIG. 9, a circuit board 17 is provided on the first side surface 15 of the ink cartridge 100. The circuit board 17 is provided at a position closer to the front end surface 11 than the rear end surface 12, particularly at a position adjacent to the front end surface 11. The circuit board 17 is equipped with a memory element (not shown) for recording information such as the remaining amount of ink and the usage history of the cartridge.
Further, the liquid remaining amount detection unit 30 is provided with a remaining amount detection sensor (sensor using a piezoelectric element) (not shown). The remaining amount detection sensor is a sensor for detecting the remaining amount of ink in the ink cartridge. At least one electrode that is electrically connected to the remaining amount detection sensor is provided on the circuit board 17.
On the other hand, as shown in FIG. 11, a device-side terminal 250 is provided on the upper side of the circuit board 17. Then, as described above, the contact 17a of the electrode of the circuit board 17 is the device side terminal 250 (see FIGS. 3, 7, and 8) when the ink cartridge 100 is installed in the cartridge slots 7A to 7E (see FIGS. 3, 7, and 8). Make contact with the contact 250a (see Fig. 3, Fig. 7, and Fig. 8). As a result, the electrode and the device-side terminal 250 are electrically conductive. The circuit board 17 is provided near the tip surface 11, and the upper positioning hole 23 for maintaining positioning accuracy is provided near the first side surface 15, so that the contact point 17a of the electrode of the circuit board 17 and the device are provided. The contact 250a of the side terminal 250 is accurately positioned.
When the ink cartridge 100 is mounted on the cartridge holder 200 of the recording device 211 (see FIG. 1) and the contact 17a of the electrode of the circuit board 17 comes into contact with the contact 250a of the device side terminal 250 of the container mounting portion 1, the circuit board 17 The memory element and the remaining amount detection sensor are electrically connected to the control circuit on the recording device 211 (see FIG. 1), and the operation of these memory elements and the remaining amount detection sensor is recorded in the recording device 211 (see FIG. 1). ) It is possible to control from the side.
As shown in FIGS. 7 to 9 and 12, the corner 27a corresponding to the side where the first side surface 15 and the fourth side surface 35b of the ink cartridge 100 intersect with each other, and the second side surfaces 25 and 4 The corners 27b corresponding to the sides where the side surfaces 35b intersect with each other have a shape cut out along the insertion direction of the ink cartridge 100 (arrow X direction in FIG. 9). That is, the corner portions 27a and 27b are provided with a pair of C surfaces 29a and 29b. Further, as shown in FIGS. 2 to 5, 7, and 8, there is no wall partitioning between the cartridges 100 inside the cartridge holder 200.
Therefore, as shown in FIG. 7, the flat, substantially rectangular parallelepiped-shaped ink cartridges 100 are vertically arranged, that is, they are arranged and accommodated in parallel with the first side surface 15 facing up and the second side surface facing down. The ink cartridge 100 is arranged in parallel so that the third side surface 35a and the fourth side surface 35b face each other between the plurality of adjacent ink cartridges 100. Then, between the adjacent ink cartridges 100, the C surfaces 29a and 29b of one ink cartridge 100 form a space 31a and 31b having a triangular cross section extending in the insertion direction of the ink cartridge 100.
On the other hand, as shown in FIGS. 2, 5, 6, and 7, the cartridge holder 200 has a triangular cross section corresponding to the notch shape (space 31) of the corner portion 27 on which the C surface 29 is formed. A guide rail 33, which is a guide protrusion, is provided along the insertion direction of the ink cartridge 100. Further, as shown in FIG. 5, a guide protrusion 265 having a triangular cross section corresponding to the upper space 31a formed by the upper C surface 29a is provided on the front side of the upper surface of the cartridge slots 7A to 7E. Therefore, of the spaces 31a and 31b having a triangular cross section, the lower space 31b serves as the installation space for the guide rail 33, and the upper space 31a serves as the installation space for the guide protrusion 265.
Further, as shown in FIGS. 3 and 4, at least in the vicinity of the attachment / detachment opening of the cartridge slots 7A to 7E, a guide protrusion 265 having a triangular cross section corresponding to the upper space 31a formed by the upper C surface 29a. Is projected. The guide protrusion 265 is arranged on the ceiling so as to face the guide rail 33 provided on the support base 241. Therefore, of the spaces 31a and 31b having a triangular cross section, the lower space 31b serves as the installation space for the guide rail 33, and the upper space 31a serves as the installation space for the guide protrusion 265.
In a structure in which a guide rail 33 having a triangular cross section corresponding to the C surface 29b is provided along the insertion direction of the ink cartridge 100, a plurality of flat substantially rectangular parallelepiped ink cartridges 100 are arranged vertically in parallel. When housed in the holder 200, guide rails 33 having substantially the same cross-section triangle can be arranged in the insertion direction of the ink cartridge 100 in the space 31b having a triangular cross-section formed in the lower part between the adjacent ink cartridges 100. Each ink cartridge 100 is guided and positioned in the cartridge holder 200 in the insertion direction by the guide rail 33. Therefore, a partition wall for partitioning the cartridge slots 7A, 7B, 7C, 7D, and 7E of the cartridge holder 200 is not required between the adjacent ink cartridges 100.
Then, in order to supply ink to the inkjet recording device 211, when pressurized air is introduced into the bag body accommodating portion 3 and the ink pack 20 is pressurized from the outside, each ink cartridge is as shown by an imaginary line in FIG. In case 5 of 100, a pair of maximum planes (third and fourth side surfaces) 35a and 35b that are mainly parallel are expanded and deformed. The amount of expansion and deformation varies depending on various conditions such as the size of the cartridge 100, the material of the case 5, and the pressure of the pressurized air introduced into the bag-to-accommodation portion 3, but for example, the pressure of the pressurized air is 12 to 18 kPa. In the case of, the maximum one side may be about 5 to 10 mm.
In the present embodiment, since there is no partition wall in the cartridge holder 200, when pressurized air is introduced into the bag body accommodating portion 3, the maximum surfaces 35a and 35b of the adjacent case 5 expand and deform. Then, in the cartridge slots 7A to 7E having no partition wall, at least a part of the maximum surfaces 35a and 35b of the adjacent ink cartridges 100 come into contact with each other and are pressed against each other.

On the other hand, when the pressurization of the pressurizing chamber is released and the expanded ink cartridge 100 returns to its original shape, there is no pressure contact between the adjacent ink cartridges 100 or between the cartridge 100 and the support side wall 262. Each ink cartridge 100 can be attached and detached smoothly.
FIG. 13 is an enlarged view of part B of FIG. 12, and FIG. 14 is an enlarged plan view of the guide groove shown in FIG. As shown in FIGS. 12 and 13, the second side surface 25 has a cartridge slot in a state where the ink cartridge 100 is mounted in the cartridge slots 7A to 7E against the urging force in the direction opposite to the insertion direction. In cooperation with the device-side fixing structure 50 provided in 7A to 7E, a container-side fixing structure 40 that restricts the movement of the ink cartridge 100 in the direction opposite to the insertion direction so as to be released is provided. The device-side fixing structure 40 is provided at a position closer to the front end surface 11 than the rear end surface 12, particularly at a position adjacent to the front end surface 11. Further, a recess 43 is provided on the second side surface 25 at a position farther from the tip surface 11 than the container-side fixed structure 40. Although the recess 43 is not adjacent to the front end surface, the recess 43 is provided at a position closer to the front end surface 11 than the rear end surface 12.
As shown in FIG. 13, the container-side fixed structure 40 is locked when the locking pin 37 of the device-side fixed structure 50 (see FIG. 3) is inserted and the ink cartridge 100 is attached / detached to / from the cartridge slots 7A to 7E. It has a guide groove 39 that guides the locking pin 37 as a member to a locked position or a non-locked position. Further, in the container-side fixed structure 40, when the ink cartridge 100 is mounted in the cartridge slots 7A to 7E, the locking pin 37 is engaged to restrict the movement of the ink cartridge 100 in the withdrawal direction.

As shown in FIG. 13, the guide groove 39 is inserted into the inlet side guide portion 51 for guiding the locking pin 37 and the cartridge slots 7A to 7E when the ink cartridge 100 is inserted into the cartridge slots 7A to 7E. An intermediate guide portion 53 that guides the locking pin 37 to the locking portion 49 when the ink cartridge 100 is pushed back in the pull-out direction, and an insertion direction of the ink cartridge 100 when the ink cartridge 100 is removed from the cartridge slots 7A to 7E. It is provided with an outlet side guide portion 55 that guides the locking pin 37 released from the locking portion 49 by pushing into the guide groove 39 to the outlet of the guide groove 39.
The outlet portion 57 of the guide groove 39 is connected to the inlet portion 59, whereby the guide groove 39 forms a loop as a whole. At the connecting portion between the inlet portion 59 and the outlet portion 57, the depth of the groove of the outlet portion 57 is shallower than the depth of the groove of the inlet portion 59, whereby a step 65 is formed at the connecting portion. The step 65 prevents the locking pin 37 from entering the outlet portion 57 when the ink cartridge 100 is inserted into the cartridge slots 7A to 7E.
On the other hand, as shown in FIG. 9, a device-side fixing structure 50 is provided below the container-side fixing structure 40. As described above, the device-side fixing structure 50 includes the lever member 45 and the spring 44 shown in FIG. 6 (b).
The lever member 45 is urged by a spring 44 in a constant rotational direction. This direction is the arrow-R direction in FIG. 6 (b) and the counterclockwise direction in FIG. When the ink cartridge 100 is attached to and detached from the cartridge slots 7A to 7E, the locking pin 37 is inserted into the guide groove 39 and guided, and the lever member 45 rotates in the ± R direction according to the shape of the guide groove 39.
As shown in FIG. 11, the locking pin 37 provided at the tip of the lever member 45 is provided in the direction intersecting the second side surface 25 of the ink cartridge 100. When the locking pin 37 is inserted into the guide groove 39, the locking pin 37 presses the bottom surface of the guide groove 39 upward by the elastic force of the lever body 47 constituting the lever member 45.
Next, the operation of the locking pin 37 in the guide groove 39 during the attachment / detachment operation of the ink cartridge 100 will be described mainly with reference to FIG. When the ink cartridge 100 is inserted into the cartridge slots 7A to 7E and the ink cartridge 100 is further pushed in the insertion direction against the urging force of the slider member 244 (see FIGS. 4 and 5), the locking pin 37 is moved to the guide groove 39. It is inserted into the entrance 59 of the.
The locking pin 37 is urged toward the bottom surface of the guide groove 39 by elastically deforming the lever body 47 (see FIG. 6) of the lever member 45 (see FIG. 6). When the locking pin 37 crosses the end of the inlet side guide 51, it moves counterclockwise in FIG. 14 due to the urging force of the spring 44 (see FIG. 6). Then, the locking pin 37 collides with the temporary stop side wall portion 61 and stops, and at this time, a clicking sound is generated. This click sound allows the user to confirm that the ink cartridge 100 has been inserted sufficiently deeply.
Next, when the pressure in the insertion direction by the user is released, the ink cartridge 100 is slightly pushed back in the pull-out direction by the urging force of the slider member 246 (see FIGS. 4 and 5). As a result, the locking pin 37 is disengaged from the temporary stop side wall portion 61, and the locking pin 37 moves in the counterclockwise direction by the urging force of the spring 44. Then, the locking pin 37 collides with the final stop side wall portion 63 provided in the locking portion 49 and stops at the locking position, and at this time, a clicking sound is generated. This click sound allows the user to confirm that the ink cartridge 100 is fixed in the cartridge slots 7A to 7E (see FIGS. 2, 4, 5, 7, and 8). Even when the ink cartridge 100 is mounted in the cartridge slots 7A to 7E, the locking pin 37 presses the bottom surface of the guide groove 39 by the elastic force of the lever body 47.
When the cartridge is attached or detached, the locked ink cartridge 100 is pushed in to disengage the locking pin 37 at the final stop side wall portion 63, and the urging force applied to the lever member 45 by the spring 44 causes the ink cartridge 100 to be disengaged. , The locking pin 37 moves relative to the non-locking position along the exit side guide portion 55. Then, the cartridge 100 is pushed forward by the urging force of the slider member 246 (see FIG. 3). With the movement of the cartridge 100 at this time, the locking pin 37 heads toward the outlet portion 57. Finally, when the locking pin 37 is pulled out from the outlet portion 57, the ink cartridge 100 can be removed from the cartridge slots 7A to 7E. As shown in FIGS. 12 and 13, a recess 43 is provided on the second side surface 25 of the ink cartridge 100, but the recess 43 does not have a special function.
Next, with reference mainly to FIG. 11, the positions of the device-side terminal 250 and the locking pin 37 when the ink cartridge 100 is mounted, that is, when the locking pin 37 is locked to the locking portion 49.

Therefore, it is not necessary to arrange the plurality of ink cartridges 100 apart from each other by the amount of the partition wall and the guide protrusion 33. That is, it is possible to store a plurality of ink cartridges 100 in close proximity (high density). Therefore, it is possible to form a compact cartridge holder 200 having a small total accommodation width dimension in the thickness direction of the container. In addition, the entire inkjet recording device 211 can be made compact.
Further, according to the present invention, as described above, when the ink cartridge 100 is pressurized, the expansion and deformation of each container is regulated, so that the deviation between the device side terminal 250 and the contact 17a of the circuit board 17 is regulated. Can be prevented, and the deterioration of these electrical connectivity can be prevented. Further, the load applied to the engaging portion between the device-side fixed structure 50 and the container-side fixed structure 40, which will be described later, can be reduced. Further, since the plurality of ink cartridges 100 are firmly and integrally fixed to the cartridge slots 7A to 7E by their own expansion force, it is not necessary to provide the holder 200 with a partition wall for partitioning the cartridge slots 7A to 7E, and the holder 200 Can be simplified and miniaturized.
Further, the contact point 17a of the electrode of the circuit board 17 and the container-side fixed structure 40 are arranged on the first side surface 15 and the second side surface 25 of the ink cartridge 100, respectively, so that the third side of the adjacent cartridge 100 can be used. Since it is not necessary to dispose the device-side terminal 250 or the device-side fixed structure 50 between the side surface 35a or the fourth side surface 35b, it is possible to accommodate a plurality of ink cartridges 100 at high density. That is, according to the present embodiment, it is possible to accommodate a plurality of ink cartridges 100 at a high density without deteriorating the electrical connectivity between the device-side terminal 250 and the contact 17a of the circuit board 17.
Further, as shown in FIGS. 2 and 5, in the present embodiment, the guide rail 33 faces the third side surface 35a or the fourth side surface 35b of the ink cartridge 100 in a direction parallel to the vertical plane. It is provided on a substrate 241 on which a plurality of sheets are placed side by side in parallel. Therefore, when the ink cartridge 100 is mounted in the cartridge slots 7A to 7E, the guide protrusion 33 is arranged at the lower part between the adjacent ink cartridges 100. That is, when the ink cartridge 100 is attached / detached to / from the cartridge slots 7A to 7E, the lower portion of each cartridge 100 is guided. Therefore, the operation of attaching / detaching the cartridge 100 becomes easy. Further, the cartridge 100 is more reliably positioned in the cartridge slots 7A to 7E.
Further, as shown in FIGS. 3, 4, and 7, in the present embodiment, the guide protrusion 265 is provided so as to face the guide rail 33. Therefore, when the ink cartridge 100 is attached / detached, not only the lower surface side of the ink cartridge 100 is guided by the guide rail 33, but also the upper surface side is guided by the guide protrusion 265, which makes it easier to attach / detach the ink cartridge 100. Of course, the cross-sectional shapes of the guide rail 33 and the guide protrusion 265 (see FIG. 4) are not limited to triangles as long as the ink cartridge 100 can be inserted and guided, and various cross-sectional shapes can be adopted. Further, the shape of the C surface can be appropriately changed according to the cross-sectional shape of the guide rail 33 and the guide protrusion 265. Further, the guide protrusion 265 (see FIG. 4) may be omitted, and in this case, the C surface 29a corresponding to the guide protrusion 265 may be omitted. Furthermore, depending on the shape and position of the guide protrusion 265 (see FIG. 4) and the guide rail 33, the C surface 29a or C surface 29b corresponds to the side where the third side surface 35a and the first side surface 15 intersect with each other. It may be provided at the corner 27c (see FIGS. 9 and 12) or at the corner 27d (see FIGS. 9 and 12) corresponding to the side where the third side surface 35a and the second side surface 25 intersect with each other. It is possible. That is, the C surface may be provided on at least one of the four corners 27a to 27d corresponding to the sides where two of the first to fourth sides 15,25,35a, and 35b intersect with each other. ..
Further, as shown in FIG. 10, in the present embodiment, the pressurizing chamber of the ink cartridge 100 is provided with a box-shaped bag body accommodating portion 3 having one open surface and a sheet film 24 for sealing the open surface. A compartment is formed. Therefore, the sealed structure of the bag body accommodating portion 3 and the ink pack 20 can be easily configured, and the manufacturing cost can be reduced.
In this embodiment, as shown in FIGS. 9, 11, and 12, the ink cartridge 100 is provided with a pair of positioning holes 21, 23. Further, as shown in FIGS. 4 and 5, the cartridge slots 7A to 7E are provided with a pair of positioning pins 247,247 that are fitted with a pair of positioning holes 21 and 23. As a result, the ink cartridge 100 can be mounted in the cartridge slots 7A to 7E with an accurate inclination, so that the operation of mounting the ink cartridge 100 in the cartridge slots 7A to 7E becomes easy. Further, it is possible to prevent the circuit board 17, the device-side terminal 250, the container-side fixed structure 40, the device-side fixed structure 50, and the like from being damaged by the ink cartridge 100 being attached and detached at an incorrect inclination. Further, when the ink cartridge 100 is mounted in the cartridge slots 7A to 7E, the continuity between the circuit board 17 and the device side terminal 250 and the fixed state between the container side fixed structure 40 and the device side fixed structure 50. Can be maintained in good condition.
Further, in the present embodiment, as shown in FIG. 11, the pair of positioning holes 21, 23, the circuit board 17, and the container-side fixed structure 40 are arranged on substantially the same vertical cross section AA (see FIG. 8).

With this configuration, when the ink cartridge 100 is inserted into the cartridge slots 7A to 7E and the pair of positioning pins 247 and 247 are fitted into the pair of positioning holes 21 and 23, the cartridge 100 is oriented along the tip surface 11 ( That is, it is positioned in the direction parallel to the vertical cross section), and the contact 17a of the circuit board 17 and the contact 250a of the device side terminal 250 located on one side of the vertical cross section, and the container side fixed structure 40 and the device side located on the other side. Each of the fixed structures 50 is positioned with high accuracy in the approaching / separating directions.
In the present embodiment, as shown in FIG. 7, the flat substantially rectangular parallelepiped-shaped ink cartridges 100 are arranged vertically and in parallel, but the ink cartridges may be arranged so as to be stacked in the vertical direction. That is, the third side surface 35a or the fourth side surface 35b of the ink cartridge 100 may be arranged so as to face each other in a direction perpendicular to the vertical plane. However, it is better to arrange them vertically and in parallel as in the present embodiment, in particular, to provide the first side surface 15 on which the circuit board 17 is provided, the device-side terminal 250 on the upper side, and the container-side fixed structure 40. If the side surface 25 of 2 and the device-side fixed structure 50 are arranged so as to be on the lower side, when ink leaks from between the ink supply port 7 and the ink supply pin 249, the leaked ink causes the circuit board. It is advantageous in that 17 can be prevented from becoming electrically defective.
Further, in the present embodiment, the circuit board 17, the positioning hole 21, and the ink supply port 7 are all integrated on the upper side. As described above, by arranging them close to each other, the positional accuracy of the circuit board 17 and the device side terminal 250, and the positional accuracy of the ink supply port 17 and the ink supply pin 249 can be improved. By providing the ink supply port 7 on the upper side, the discharge port 20a of the ink pack 20 can be arranged on the lower side, and the initial static pressure can be reduced. That is, if the first side surface 15 is arranged on the upper side and the second side surface 25 is arranged on the lower side as in the present embodiment, the positional accuracy of the circuit board 17 and the device side terminal 250 and the ink supply port 17 It is easy to realize a configuration that can reduce the initial static pressure while improving the positional accuracy of the ink supply pin 249.
Further, in the present embodiment, as shown in FIG. 11, the circuit board 17 and the container-side fixed structure 40 are arranged at positions closer to the front end surface 11 than to the rear end surface 12. Then, when the ink cartridge 100 is inserted into the cartridge slots 7A to 7E, the urging means of the device-side fixing structure 50 causes the locking pin 37 to press the bottom surface of the guide groove 39 of the container-side fixing structure 40 upward. The locking pin 37 is urged to. That is, the second side surface 25, which is the lower surface of the ink cartridge 100, is pressed by the locking pin 37 toward the first side surface 15, which is the upper surface. Therefore, the contact 17a of the circuit board 17 provided on the first side surface 15 of the ink cartridge 100 is pressed against the device-side terminal 250 of the inkjet recording device 211 (contacts 17a and 25a are brought close to each other). The electrodes of the circuit board 17 and the device-side terminals 250 are securely connected.
In particular, in the present embodiment, as shown in FIG. 11, the contact 250a is attached to the locking portion 49 when the ink cartridge 100 is mounted, that is, when the locking pin 37 is locked to the locking portion 49. It is in contact with the contact 17a at a position closer to the tip surface 11 of the ink cartridge 100 by the dimension S than the position of the locked locking pin 37. In this state, the locking pin 37 of the device-side fixed structure 50 presses the bottom surface of the guide groove 39 of the container-side fixed structure 40 upward, so that the front end surface 11 side of the ink cartridge 100 is the support portion 70 on the rear end surface 12 side. It is rotated upward around the center.
Then, the contact 17a of the electrode of the circuit board 17 provided on the first side surface 15 is pressed against the device side terminal 250, and the contact 17a is the guide groove 39 of the container side fixed structure 40 by the locking pin 37. It moves to the device side terminal 250 side more than the amount of movement of the bottom surface. As a result, the contact 17a is more strongly pressed against the device-side terminal 250, and the electrode of the circuit board 17 and the device-side terminal 250 are more reliably connected.
