Xerographic copier display panel
Abstract
@ A display for use in conjunction with a copier. The disclosed display comprises two microprocessors (210. 212) for controllably displaying information on a display panel (20) of a xerographic copier (10). A first microprocessor is primarily responsible for energizing alphanumeric elements to either send messages to the copier user or to prompt the user to interact with the copier. A second display (24) is a liquid crystal display wherein selectively energizable liquid crystal elements corresponding to copier components can be rendered visible under the control of the second microprocessor. An overlay pattern (149) can be placed above the liquid crystal display to present to the user in outline form the copier architecture with which he is interacting. This overlay can be changed as the copier configuration is changed. The electronics for controlling the display of alphanumeric allows the utilization of different fonts and/or different languages. This flexibility allows the copier to prompt, and/or display informaton regarding copier status in various languages without a redesign of the display unit. -->

The present invention relates to an electrostatic copying machine and goes more particularly on a display panel that keeps the user of the copying machine notified copying machine status as respect of the user to interact with the copy machine.
As the electrostatic copying techniques have evolved has also the construction of the electrostatic brand machines used for the practical implementation of xerography evolved. Electrostatic copying machines are now capable of automatically producing two-sided copies from originals with different front and rear as well as stacking a desired number of stapled copy sets in a utmatingskurv. There are such copying options on the same fundamental electrostatic labeling machine, so that while one copier may have a recirculating docu-ment-handling device for automatic feeding of original documents past a copying sheet, another just a copying plate with lid and requiring that user inputs and copies each original individually. The fact that there are different options allows the user to satisfy their copying needs with the most efficient use of money.
There are certain bekvemmelighetsanordninger making it easier for the user to interact with the copy machine. Automatic billing equipment gives example. user will automatically know which client the particular job that runs on the copying machine is performed for and also how many copies this particular job entails. Other bekvemmelighetsanordninger connected the electrostatic copying machine enables the user to interact with the copying machine in a more efficient and intelligent manner. Human Factors Engineering has made it easier for an unholy operator to learn how copying machine works and how to diagnose and correct errors that may occur when two copying machine is in operation. This training and / or copying machine diagnostistikk are naturally more complicated as copying machines become more and more advanced. If the operator also has knowledge of one type of copier and encounter a differently designed copier, he may be predisposed for a diagnostic procedure that is unsuitable for the new machine.
Alphanumeric display panels have been used as well to incite as to alert the user about the copy machine's status and shortcomings. Statements such as "Emergency", "Wait", "Ready", "Food Inn Documents" and "Select Number Copy" has been used to alert the user about copying machine status and function. Similar Display Units has generated alphanumeric error codes that refer the user to a flip-chart gives instructions on how to correct various problems and / or missing an encounter during copying machine operation.
Although they are not commercially exploited to the same degree as. alphanumeric data displays, it has been proposed graphical data displays as means to further educate copier user concerning the copying machine status. These graphic display panels or icons graphically illustrates one kopieringsmaskins configuration and may include the use of selective energiserbare elements that give cues to the user regarding which party of copying machine that need attention and / or repair. In a copying machine comprising a recirculating docu-ment-handling device may be a flashing icon of the document-handling device positioned relative to the other copying machine notify the user of a cork in the paper circulated in document-handling device. One such way to give cues to the user can be particularly effective in combination with an alphanumeric message left to enforce user's perception that he / she has received lessons regarding the origin of his / her problem.
As discussed above, a user may require that a copier is designed depending on his / her needs without changing the basic structure of the electrostatic mark machine. The Human Factors Engineer is consequently facing a problem with the status and / or lack information regarding a copier that can be designed in a number of different ways. This issue copying machine interface is done 3 more difficult if the copying machine is used in areas where it speaks different languages. The alphanumeric display panel that matched for an English speaking country would thus be inappropriate in a country where only spoken Spanish. Some places (eg. Quebec) require a copy machine that communicates in two languages for which a significant percentage of people speaking different languages. The engineer is then faced with the problem of whether to design a special display panel for each copying machine construction and geographical location or attempting to construct a system that is sufficiently generic to suit every possible Duplicating machine designs and languages.
The present invention relates to a method and apparatus for displaying the copying machine status information to a user. The present display panel acts in conjunction with different kinds of electrostatic copying machine forms and can be easily modified to represent alphanumeric information in different kinds of languages. The display panel has its own. programmable controller that interacts with other electronics inside the copying machine to monitor copying machine status and update user copying machine status during operation.
The display panel includes a message generation panel having a number of individually addressable character generators which can be activated and made visible. The panel further includes a liquid-crystal display screen having a pattern of energiserbare elements which correspond to various copier components.
Circuits are connected as well as the display message generator panel to coordinate the visible message displayed by the message generator panel with energization of the liquid crystalline number elements to inform the user viewer, copying machine status. Provision is made for an overlay that shows off the special kopieringsmaskins configuration.
'These overlays can be changed for different copier selections.
The use of overlays representing a particular copier configuration allows the use of a single fly-sealing-crystal display screen for each of a plurality kopieringsmaskinkonf igurasjoner. This liquid-crystal display screen shows off the outline of the various copier components such as a copying sheet, trash, utmatingskurv finalization station.
In a preferred embodiment of the invention four liquid-crystal monitor over thirty actuatable elements (a larger number is possible) which can be turned on in either a flashing or continuous manner.
In connection with the liquid-crystal monitor working message generation panel which in a preferred embodiment of the invention comprises a vakuumfluorescensskjerm with a capacity of displaying forty alphanumeric characters. Each alphanumeric character comprises a 5 x 7 in point display screen which when activated by the controller coupled to the display depicts a specific character. The particular font for the display panel is stored in the outer steering or control sake stock and in accordance with the preferred embodiment stored in a nonvolatile read only memory chip. By replacing with a different stock, a different font or languages easily displayed on signs generation screen.
Drawing screen and the liquid-crystal work together to update the user concerning the copying machine status. The programmable unit responsible for the displays operation is continuously updated regarding the copying machine status using a special programmable device. This second programmable device adapts with a plurality of sensors or transducers placed throughout the copying machine. An example is that a sensor placed in the main trash senses the lack of paper in this basket and sends a signal to the main processor when trash is empty. Main processor instructs when the processor is responsible for energizing the display panel that the trash is empty. The other programmable device then causes the occurrence of a message on the sign message-generating apparatus indicating that it should be supplied paper to the trash. At the same time affects the other external controller computer to cause energization of a liquid crystal element that indicates to the user that the trash needs attention. This liquid crystal element 'is designed for graphically representing the trash and placed in relation to overlay or outline of kopieringsmaskinkon-figuration, to easily inform the user about how trash is located.
It is no doubt have been apparent from the foregoing that an object and an advantage of the invention consists in the coordination of an alphanumeric and graphic copier status update to the user. Other objects and advantages of the invention as well as moves 5 thereof will be better understood on the basis of the following detailed description of a preferred embodiment of the invention with reference to the medføglende drawings, in which:

Referring to the drawings, particularly FIG. 1, there is shown a copier 10 suitable for preparing electrostatic copies from original documents. The copier 10 includes a box 12 that provides an attractive appearance and enveloping copier components to be described in connection with other drawing figures. The particularly illustrated copying machine 10 includes a copy sheet and a copying 6 ring plate lid 14 but no automatic document håndteringsanord solution. Copying Plate lid 14 is hinged to enable the user to raise and lower the lid 14 and entering document originals of copying disc copying. The copier 10 includes a sorter 16 which provides for collated copy sets of multi-document originals. A control panel 18 enables the user to select the copy size, copy contrast, number of copies to be produced and the way (eg. Bidirectional) copies should be made on. On the panel 18 there is also a button to initiate the copy function.
A display panel 20 informs the user about the copy machine 10 status and can be used to prompt the user to grasp corrective in case of a failure in copying machine operation. The display panel 20 includes a flip-form 22, an LCD monitor 24, an alphanumeric display screen 26 and a "power on" button 27. The present invention relates to features of r interaction between LCD computer screen 24 (digits panel with liquid crystal indicators) and the alphanumeric display screen 26 in order to effectively inform the user concerning the copying machine status, inform him / her about certain shortfalls as they occur, and refer the user to flip-form 22 in case the instructions to be given is more complicated than they can conveniently be displayed LCD computer monitor 24 and the alphanumeric display screen 26.
When the user approaches the copying machine 10 is as well LCD as the alphanumeric display screen 24, 26 glossy and can not display anything until the user activates the "power on" switch 27 for energizing power device inside the copying machine 10. Once the effect has been turned on, a "be-implement" message will appear on the alphanumeric display screen 26 indicating that copying machine is not yet ready for use.
Once copying machine 10 is ready to create electrostatic 'copies, shows the alphanumeric display screen 26 a "Ready to make copies" message that tells the user that the copying machine 10 is ready for operation.
Many of the components used in the preparation of electrostatic copies is schematically shown in FIG. 2. As shown in FIG. 2, the illustrated electrostatic photographic copying machine 10 a belt 28 with a photoconductive surface. The belt 28 moves in the direction of arrow 30 to advance successive portions 7 of the photoconductive surface through the various processing stations disposed about the belt.
Initially passing a portion of the photoconductive surface through charging station A. At charging station A charges a corona generating device, generally designated with reference numeral 32, the photoconductive surface to a relatively high, substantially uniform potential.
Then moves the charged portion of the photoconductive surface advanced through an imaging station B. At imaging station B places a document handling device, generally indicated by reference numeral 34, the original document 36 with the image surface down over an exposure system 38. In this regard, it should be note that the apparatus of FIG. 2 differs from that in FIG. 1 showed a copier in that the latter do not have any document-handling device. However, as will be appreciated works display panel 20 in connection with one and r another embodiment.
Exposure System, generally designated by the numeral 38, includes a lamp 40 which illuminates the document 36 located on a transparent copy plate 42. The light rays reflected from document 36 is passed through a lens 44. The lens 44 focuses the slide of the original document 36 onto the charged portion of the belt 28 photoconductive surface to selectively use up the charge. This records an electrostatic latent image on the photoconductive surface which corresponds to the information areas within the original document. Then move the belt 28 is the electrostatic latent image on the photoconductive surface to a developer station C. Copying plate 42 is mounted movably and arranged to move to adjust the magnification of the original document is reproduced. Lens 44 moves in synchronism with the same to focus slide of original document 36 onto the charged portion of belt 28 photoconductive surface.
* Document-handling device 34 feeds documents sequentially cially from a stack of documents by the operator is placed in a normal forward collated order in a dokumentstable- and up-retention basket. The documents are fed sequentially from storage curve to copy the disc 42. Document-handling device recirculates documents back to the stack supported on the curve. Document-handling device is preferably arranged for sequential feeding of the documents in the series, the eight documents may have different sizes and paper weights.
Even though this is accounted for a document-handling device, the skilled artisan will readily appreciate that the original document can be placed by hand on the copy disc instead of using document-handling device. This is necessary when a copy machine which includes a document handling device (the copying machine of Fig. 1).
With continued reference to FIG. 2 it will be seen that the developer station C carries a pair of magnetic brush developer rollers, indicated generally by reference numerals 48 and 50, a developing material into contact with the electrostatic latent image. The latent image attracts toner particles from bærepartik-lean of developing material for forming a toner powder image on belt 28 photoconductive surface.
After the electrostatic latent image on the belt 28 photoconductive surface is developed, moving belt 28 tonerpulver- * image until a transfer station D. At transfer station D carried a copy of the transfer relation with the toner powder image. Transfer station D includes a corona generating device 52 which sprays ions onto the back of the copy sheet. This attracts the toner powder image from the belt 28 photoconductive surface of the sheet. After transferring moving a carrier 54 sheet until a melt drive E. Copy sheets are fed at the option of one of the curves 56 or 58 of the paper web 59 and the transfer station D.
Melting station E includes a melting device which serves to attach the transferred powder image permanently to the copy sheet. Melting device preferably includes a heated melt roll 62 and anvil roll 64. The sheet passes between melt roll 62 and anvil roll 64 with the powder image contacting melting roller 62. In this way the powder image permanently affixed to the sheet.
After melting transports a carrier 66 sheets to gate 68 which functions as a phase inverter stage selector. Depending on your door 68 position will copy sheets will either be deflected into a arkfasevendertrinn 70 or moved past said phase inverter stage 70 and fed directly onto another decision sports 72. copy sheet thus recorded off sheet-phase inverter stage 70 rounds a 90 ° corner before they reach gate 72. When the gate 72 is oriented sheets face up, so that the mapped page 9 has been transferred and fused is correspondingly oriented. If the inverting step path 70 is selected, the opposite is the case, ie the last copied surface is facing down. The second decision sport "72 deflects the sheet directly into a utmatingskurv 74 or deflects the sheet into a transport path which carries the sheet to a third decision port 76. The port 76 provides either the sheets directly on without inversion to the copier output, or directs the sheets to a bidirectional deflection roller 78 . the turning roller 78 faces and stacks sheets to be duplicated in a duotone curve 80 when the gate 76 leads so. Duotone curve 80 provides intermediate or buffer storage for those sheets that have been copied on one side and on which it will later be copied an image on the opposite side, ie the copy sheet as duplicated. Because of the roller 78 sheet-ven-tions function they stack buffer fixed sheet in duotone curve 80 face down in the order sheets have been copied in.
To complete duplex the previously simplex copy sheets in curve 80 fed in succession by means of an underlying feeder 82 back to transfer station D for transfer of the toner powder image to the opposite side of the sheet. Conveyors 84 and 86 causes the sheet forward along a path that provides an inversion thereof. Inasmuch as the bottom sheet is fed from the duotone curve 80 is, however, the proper or clean side of the copy sheet disposed in contact with belt 28 at transfer station D so that the toner image on the transfer to this. Dupleksarkene then fed through the same path as the previously simplekskopierte sheets to be stacked in the cart 74 for subsequent removal.
For now return to the copy machine operation, it will after the copy sheet is separated from the photoconductive surface of belt 28 adhesive some residual particles to the belt. Di ting restpartik particles are removed from the photoconductive surface thereof by the cleaning station F. Cleaning station F includes a rotatably mounted børsfe 88 in contact with the belt 28 photoconductive surface. These particles are washed away from the belt 28, photoconductive surface by the rotation of the brush concern. After cleaning illuminating a discharge lamp (not shown) the photoconductive surface to dissipate any electrostatic charge before the charge for the second subsequent imaging solution cycle.
The functioning of the components of FIG. 2 comprising 10 copying machine 10 is controlled and monitored by an electronic subsystem 110 (FIG. 3) comprising a plurality of programmable controllers that communicate with a central main processor 112. An interface 114 between the control panel 20 and hovedproses-sponsor 112 notifies the processor 112 of feeds made by the user regarding number of copies, etc. the main processor 112 responds to user inputs by executing its operating system stored in a main memory unit 116.
The algorithm in main memory 116, the main central processor 112 to communicate along a communications data bus 118 to a plurality of electronic remote units 120-125 used to monitor and control the copying machine. The particular device varies with the copying machine structure so that outline diagram of FIG. 3 is representative of one of many possible outline diagrams for electrical subsystems. Each unit 120-125 has its own microprocessor with accompanying stock (as well direct memory as read-only memory) and carry circuit.
LCD and alphanumeric data displays 24, 26 are electrically connected to a display console remote unit 125, which receives status information, misinformation or program control information from the main CPU 112 and then displays until an appropriate message on the alphanumeric display screen 26 and, if appropriate, energizes one a plurality of liquid crystal segments on the LCD computer monitor 24.
Both the alphanumeric display screen 26 and the liquid-crystalline tall-monitor 24 appears more clearly from FIG. 4, which shows an enlarged view of the front panel. As is apparent from this figure, the liquid-crystal monitor 24 mounted directly above the alphanumeric display screen 26 and placed aside for flip-spoon-diagram 22. The alphanumeric display screen 26 comprises a vacuum picture tubes which are able to. generate messages that are useful to the user of the copying machine. Each of a maximum of forty - character is generated by a 5 x 7 dot pattern where each of the thirty to five points, comprising 5x7 points, may be energized individually. The application of 5 x 7 points allows not only the use of Latin characters for generating information in English but can also be modified to provide various typefaces to present messages in other languages that require completely different character sets.
The liquid-crystal display screen 24 located directly above the alphanumeric display screen includes various liquid crystal 11 segments to assist the user of copying machine by as well to cooperate with the copying machine to correct errors if such should occur during operation. The computer screen 24 is a graphical monitor of impersonator type where the particular copier design that the user interacts with are outlined on the computer screen. Sketch or outline is separated from the liquid-crystal display screen so that it can be changed in accordance with the copying machine architecture. By the illustration of FIG. 4 is copying machine left the front door open so that the liquid crystal elements that illustrate this door thousands-giseres and a message appearing on the alphanumeric display screen 26, indicating that the left front door has been left open.
Referring now to FIG. 5, there is shown a pattern of liquid crystal elements aE as they are formed on the liquid-crystal monitor. The following table indicates the component or condition every item in the data table represents.

Upon review of the elements in the preceding table, R <artisan understand that any individual copier machine embodiment will not comprise all of the elements indicated * in the table. It is no doubt therefore be apparent that a copier configured to include a single sorter such as that illustrated in data screen of FIG. 4 will not include those elements associated to a stacking means. The liquid-crystal monitor 24, however, includes all the elements listed in the table and it is the function of the control electronics in the monitor console remote unit 125 to distinguish copier machine design and only energize an appropriate element in the multi-elementdataskj sleeve.
Each liquid crystal computer monitor is using a conductive path connected to an individual power outlet at the bottom of the computer screen, which allows the computer screen 24 able to be inserted into a shelf below the computer screen. When a particular conductive path is energized with a voltage signal, is energized • the segment coupled to the individual socket and causes the latter portion of the computer screen is visible. Detailed - information on how liquid crystals works can be found in the literature, and has therefore not found it necessary to go into detail about how particular elements formed in the computer screen. The special monitor shown in FIG. 5 is formed by the assignee of the invention and are obtained from Crystaloid Electronics Company, Hudson, Ohio 44236. In essence comprising the 13 liquid crystal monitor 00:02 layers of glass pressed together to form a layered sheet 130 mounted by front 132 and rear 134 support elements enclosing plate 130 circumference. These layered plates comprises polarizing material needed to make the liquid crystal elements formed in the middle between the two plates visible. A picture tube 138 (FIG. 6A and 6B) directs light through a chamber 140 behind the computer screen which is bounded by a reflective surface 142 made of ABS white plastic. When the liquid crystal elements aE is in a uenergisert state, permits the front and rear polarizers that only blue light is reflected from surface 142 reaches the user. When one of the polarizable elements in the liquid crystal is energized, however, permits the combined effect of the three polarized segments, i.e. the front and rear polarized layers in combination with the electrically polarized liquid crystal element that white light reflected by the surface 142 and front r .
serer through the energized segment of the liquid crystal to the user. Thus, when an appropriate one of the liquid crystals * energized by a signal from the monitor console remote unit 125, it is made visible as a result of the passage of white light through this segment. This segment is of course bounded by a blue field. Alternative computer screen designs such as a colored liquid crystal on a white background is possible. It is also possible that both the background as the liquid crystals can be colored. A colored liquid crystal uses only one polarizer and the color constitutes a natural constituent of the liquid crystal material. Certain dichroic and diazo dyes used for the implementation of colored liquid crystals.
The skilled person is aware that the liquid crystal segments will be damaged if the energizing signal from monitor console f iron device 125 is a direct current condition. Consequently energized the liquid crystals to remain visible • with a 42 Hz signal rather than a continuous signal. If a liquid crystal device to blink on and off, the liquid crystal will be energized with a 42 cycles per. second signal made without power in a certain blocking period and then again will be energized by the alternating signal frequency. CRT 138, the reflective surface 142 and the liquid-crystal monitor are each mounted on a printed circuit board 144 comprising a portion of the monitor console f iron device 125. Once the layered sheet 130 14 has been inserted into a socket 146, disposed a front mounting-bracket 148 over the computer screen to keep it in place. The console or bracket 148 includes slotted hole in one for voltage through which the threaded sockets (not shown) is inserted so that they intervene in the monitor body. By exerting a light pressure on the top of the bracket, the layered plate automatically biased with three mounting columns 158-160. When the bracket is tightened, it holds the layered plate fixed in place so the electrical connection used to energize the liquid crystal elements is secure.
As mentioned previously, a permanently visible overlay 149 including an outline of the copier embodiment, which the user cooperates, positioned over the layered sheet 130 to help orient the user as the liquid crystal elements aE energized by monitor console remote unit 125. Eight various overlay is shown in Fig. 7A-7H. As soon as the buyer or borrower of a particular copier has determined the special design of this copier, * assembled it overlays that match this design out the liquid-crystal display screen 24 without the use of tools to facilitate the overlay into the layered plate 130, as it is held in place on the computer screen until copying machine performance changes. As shown in FIG. 7A-7H includes a typical overlay one view of a copier embodiment surrounded by a transparent piece of plastic bounded by a number of mounting tongues 150-153. Three of these mounting tongues 151-153 defines register-reringshull 154-156, which serves to direct copying machine diagram in relation to the liquid crystal elements defined by the layered sheet 130. When the overlay 149 corresponding to a particular copier embodiment is mounted on the computer screen 24, grabs three corresponding registration pins 158-160 formed in computer monitor mounting bracket into these three • recording tracks 150-156 (see Fig. 6A and 6B). As is readily evident from Fig. 7A-7H becomes at different copying machine models used different overlays and it dared furthermore be clear that the liquid-crystal monitor 24 itself includes all energiserbare elements aE regardless of the copy-machine model. As previously mentioned, serves the control electronics to ensure that the liquid crystal elements representing elements that are not included in the model never turned on to let reflective light transmission occur.

Monitor console remote unit 125 (FIG. 3) comprises two microprocessors 210, 212 (FIGS. 8 and 9). The first 210 of the two microprocessors comprise an Intel 8085 microprocessor which communicates with the main processor 112. Monitor Console remote device 125 also includes an integrated circuit 214 for spesialkom-cations by additional large-scale integration for converting signals from the main processor 112 acting on communications buses 118 in the form of serial communications packets to parallel communications for reception on 8085 data / address bus 216.
Communications chip 214 is a conventional integrated circuit to perform a communication protocol similar Ethernet®-protocols developed by the assignee of the present invention. The serial communications performed by the various processing units in the present copying machine is a similar package-transmission type, where it established a priority for message transfer and where each of the processing units 120-125 must be com- r command from communication bus 118 sending messages to other remote devices. Communications chip 214 receives packets of information which is converted into parallel signals for reception by the 8085 microprocessor 210. The typical signals along serial communication line will enter the 8085 status of the copy machine as errors and omissions which may have occurred during copying machine operation.
8085-microprocessor task is to interpret the communications appearing on its data / address bus 216 and cause it to be displayed an appropriate message as in appropriate situations energize certain of LCD segments in the computer screen 24. In the system of the invention will be very nearly af- hundreogtretti different messages along the serial communication line from the main processor 112 to 8085 microprocessor in monitor-remote unit 125. 8085 microprocessor 210 is supported by four storage units 218, 220, 221, 222. the first three of these storage • devices 218, 220, 221 comprises 8K ROM memory chips that form the direct interface with 8085 data / address bus. As the skilled artisan will understand these leselager- or ROM chips 218, 220, 221 is read by the 8085 microprocessor. It's a first 218 of these ROM chips that store 8085 operation system that interprets the main processor 112 sends serial communication messages.
The other two ROM chips 220, 221 are typical messages stored in nonvolatile memory for display on the alphanumeric data 16 screen 26. When it performs its message displaying service needs 8085 microprocessor 210 have access to certain memory locations to which it can write data so that it is also comprised a 2K direktelager- or RAM unit 222.
8085 microprocessor 210 is programmed to perform much of its input / output using the bearing depicted in feed / utmatingsteknikk. As those skilled dare be familiar with requiring the use of this technique in generation of various ready signals for bringing various circuits to either transmit data to the 8085 data bus or to read data from that bus. Genererin gene of these clear signals performed by an address decode logic circuit 224. As indicated in FIG. 8 generates the logic circuit 224 seven ROM decode signals, two RAM decode signals, a signal to decode communications chip 214 and five special input unit / will be discharged ings-decoded mation signal.
When power to the copying machine is turned on, performs opera
V
tion system stored in the first ROM memory location 218 a number of initialization before it is ready to energize the LCD computer monitor 24 or the alphanumeric display screen 26. During this up phase are the display unit 125 notified of copier configuration of the main processor 112.
Then monitors the operating system message packets from the main processor and determines whether the information it receives incorrect information, status information, or so-called program information.
A typical error message may be an indication that a front door 13 on the bin 12 is open, a typical state message may be that the copying machine is ready for use, and a typical application mode message may be that the user has decided to adjust the copy contrast and need to be prompted to do this.
A subset or subset of error messages are so-called double-error codes that may be related to two kopieringsmaskinkon-figurations. When an encounter these codes, the processor must first 4 fix copier configuration and then display an appropriate message. Each message has a unique designation * set 8085 microprocessor able to find an appropriate message for each such designation.
The decision of the message which is displayed for every meldingsutpeker or -designator performed using available function values for advance reading in one of ROM chips 220, 221. Each of these 8K language-read store has 17 three distinct lookup tables (of available funksjonsver-values pre-reading), namely one for error messages, one for status and program mode messages and one for dobbeltfeilmel-sages. As soon as 8085 microprocessor determines what kind of message it has, pointing it toward the right lookup table, offset to a degree corresponding to meldingsdesignatoren and then reads the message at this storage location from one of 8K read bearings into its RAM storage 222.
The particular message for each designator comprises a nine hovedbitgruppe and either a forty or eighty-bitgruppemelding.
The first byte in the nine-hovedbitgruppen indicates whether some LCDs in the computer screen to be activated. The next eight bytes specify which LCDs are energized and whether they should blink or remain visible continuously. Each byte in the forty (or eighty) remaining bytes match a character in the alphanumeric display screen comprising 40 characters. Each eight byte in this portion of the message corresponds to a uniquely energiseringsskjerna for the 35 points forming each vacuum fluorescent character.
By changing the ROM the message can be displayed in languages with varying alphabet fonts such as Cyrillic, Kata-KANA, etc. As also indicated above allows look-up table technique of message generation using various languages by simply changing the read bearing lookup table-8085-permissions for its message.
An interface circuit 226 (FIG. 11) for energizing particular liquid crystals in the computer monitor 24 is directly adapted to the 8085 data / address bus 216. The LCD interface comprises a serial-to-parallel shift register 228, a buffer stage 230, and two inputs 232, 234 from adressedekodingslogikkretsen 224.
Buffer stage 230 is directly coupled by connector 3 to line 0 of the 8085 data bus. When the buffer activating input by Connectio-ling pin or plug 11 of buffer step 230 is set, locked the data appearing at the connecting pin 3 of the buffer in step 230 as an output when connecting pin 2. After this confinement operation or increments transmitted output by connecting pin 2 to input by connecting pin 34 of the serial-to-parallel shift register 228. Referring to FIG. 11 will also notice that the preparatory signal for the buffer memory 230 serves as a clock signal for serial-to-parallel shift register 228, so that each time a data bit blocked by buffer step 230, it is simultaneously clocked into the serial input by made connecting 18 pin 34 of the shift register. It is no doubt also be appreciated that a second input 234 is coupled to shift register connecting pin K2 to serve as enable signal for this shift register.
Serial-to-parallel shift register 228 includes a ♦ series of 32 output pins which are directly connected to LCD segmented tabs on the computer screen 24. As soon as serial data has been loaded sequentially into the shift register 228, is available as an energizing signal to the LCD computer screen in response to a 42-period output control signal by the shift register 228 connecting pin 31 8085-clock cycle is fast enough so that the shift register can be loaded between successive pulses of 42
Hz output. To change form LCD energizing need thus 8085 microprocessor only energize the shift register's input signals, sending serial data to the shift register and await the next of the 42 periods outgoing signals. The microprocessor 210 therefore has the capacity · to energize a specific (LCD segment, so this segment are made to appear flashing on the computer screen 224. The segments can thus eg. Energized for 21 output periods, Deenergizing 21 output periods of an alternating manner to bring a chosen LCD segment to flash on and off every second.
For now return to FIG. 8 one can see that the 8085 microprocessor 210 communicates with a 8031 microprocessor 212 (FIG. 9A and 9B) along one nine bit parallel communication channel 238 which instructs the 8031 microprocessor 212 regarding the information to be displayed on the alphanumeric display screen 26. Eight of the nine bits on this parallel communications channel are coupled from the 8085 data bus 216 to an 8031 data bus 240 through a pair of data buffer memories 242, 244 (FIG. 9B). At an entrance of data communications receives a first buffer stage 242 a CLK input 243 from adressedekodings-logic circuit 224 when the 8085 microprocessor wants to send data to the 8031 microprocessor. Reception of this signal 243 provides a rocker 245 to * to cancel 8031 microprocessor with an input 248 which causes data appearing at the nine bit data channel is read by the 8031 microprocessor. One of the nine bits are received along an entrance 247 to 8031 port Pl.4. 8031-microprocessor interrupt routine first reads this piece and then reads the contents of the eight-bit buffer step 242 and stores this byte in one of the 8031-microprocessor internal registers (one of 128). Each time-8031 micro- processor 19 212 reads data from the buffer memory 242, generates a signal 250, which opens the buffer output, using an 8031 address decode circuit 252. This signal 250 resets flip-flop 245 as well.
8031 microprocessor can also transmit eight bits of data back to the 8085 microprocessor through the second 244 of the two data buffer store. In accordance with the invention, the only signal transmitted from the 8031 microprocessor 212 to the 8085 microprocessor 210 a positive acknowledgment that the data has been received from the 8085 microprocessor. Operates receives 8085 microprocessor 210 an indication from the master device to a particular copier configuration or status has been achieved or that an error has occurred. 8085 microprocessor continues through a program stored in its operating systems ROM chip to analyze the status and / or error to determine which message should be displayed on the alphanumeric display screen 26. This message is then sent from 8085- to 8031-microprocessor and stored in 8031-microprocessor internal RAM space.
The following describes the communications protocol used for communicating between 8031- and 8085-microprocessor. This protocol sends information in units called packets. The packets are capsules of information containing a hovedbitgruppe or string of data bytes. This includes a four-bit command field that describes the content of the message. Three-bit checksum more ships both in the message packet and ACKen (receipt) sent back when the package is correctly received. If it is not received an ACK within one or two milliseconds of transmission, sent the package back by 8085 microprocessor.
In addition to the packet length and the checksum contains the main record a one-bit sequence number. The ninth bitinngang at port 1.4 is used as a flag to differentiate between the main and data bytes. When this bit is fixed indicates it a hovedbitgruppe * in the gate bitgruppeseksjon. It can be considered to be the start of packet flag. 8031 routine interrupts for each new byte. written into its port. It reads bit Pl.4 to decide whether to treat a primary or bytes of data and then reads the gate bitgruppedel. 8031 microprocessor builds up packet in a buffer until it has read the number of bytes implied by the main postal kpmmandofelt. At this time, the receiver computes the checksum of the message and compare 20 it with the checksum hovedbitgruppen contains. If the control sums votes acknowledges 8031 microprocessor for the package. The receipt contains the checksum and sequence number for the packet it acknowledges. If the checksum was incorrect, or v if hovedbitgruppen of a next packet was detected before the first packet was received in full, taken no precautions and the message will be sent back. If the received message was an ACK, the transmitter will be re-activated.
8031 microprocessor must convert the data generated by the 8085 microprocessor to signals suitable for energizing the alphanumeric display screen 26. A convention employed in the present invention is a modified ASCII representation of the data board. It may therefore in 8031-microprocessor internal stock be stored 40 ASCII similar bytes representing 40 alphanumeric characters to be displayed on the computer screen. 8031 microprocessor accesses a lookup table (of available f function values for pre-reading) in their own 4K ROM or read storage 272 to find an appropriate 35 bit pattern (nine bytes of data) for display on each 5x7 point comprising the alphanumeric display screen 26.
A displayenergiseringskrets 256 is shown schematically in FIG.
9 and in more detail in FIG. 10. This circuit comprises a data store 258 with four inputs adapted 8031 data bus 240.
This stock is activated by a signal 259 from 8031 address decode circuit 252 (Fig. 9A) to get hold of four bits of data appearing on 8031 data bus and send these four pieces of data to four series-to-parallel shift registers 260-263 which in a preferred embodiment comprise Sprague 4810A shift registers.
As clearly seen in Fig. 10, each of the four entrances of the warehouse 258 an associated output coupled to one of the four series-to-parallel shift registers 260-263. These four shift registers combine to provide thirty five output signals to the thirty five locations bearing a 5 x 7-point monitor. The forty 5x7 code network comprising vacuum screen has corresponding matrix locations electrically interconnected. It is no doubt therefore be appreciated that each time a shift register generates a control signal for a given matrix bearing location sends this control signal to each of the forty code line. Only one of the characters, however, made visible, for which 8031 microprocessor also controls operation of a forty bit shift register 266 which sequentially making each 21 of the forty alphanumeric points, comprising the alphanumeric display screen active. 8031 microprocessor generates thus the pattern to be made visible on the computer screen 26 by loading the shift registers 260-263 and is likewise responsible for inspections * exchangers that the 40 elements are sequentially activated via the forty bit shift register 266.
The preferred forty bit shift register 266 comprises four Sprague 4810A shift registers connected together to form the 40 control outputs, one for each point. To begin display of the first sign, type 8031 microprocessor 212 to data store 258, so that data bit zero is fixed. This high bit rate-controlled then to forty bit shift register at the occurrence of a WR2 signal at the clock input to the shift register. This input (input) generated by the address decode circuit 252. On subsequent clock signals brings 8031 microprocessor zero bit at the end of the bearing 258 to be low so that it * Loading zeros into the shift register. While under no load timing is controlled the one high bit through all 40 positions so that all 40 matrices are sequentially made active.
The alphanumeric display screen is blanked periodically by sending a signal to the four blankingsinnganger shift register 266. This blankingsignal generated by a bearing 270 clocked by a WR3 signal to transmit a data bit zero signal corresponding to blankingsignalet. This stock blanks likewise computer monitor 26 when it receives a signal labeled RST which is generated by the master controller 112 during startup.
The timing for each character is 180 microseconds of displays followed by 20 microseconds of blank screen. To display all 40 characters requires 40 x. 200 microseconds = 8 milliseconds. Bit pattern for a subsequent character is loaded into the shift registers 260-263 as the immediately preceding character displayed.
"It is instructive to examine the operation of dataskjerm- console remote unit 125 in case of a fault such as an unintentional. tet opening of the left front door 13 on the copying machine 10.
When the left front door 13 is open, the main control unit 112 will be immediately notified of this fact by an input from the electrostatic remote unit 122. Obtaining this designation will bring the central CPU for generating a signal for transmission to the computer screen remote unit 125 indicating that a 22 front left door panel has been left open. This feilsig-nal received by the monitor console remote unit 125 and examined to determine whether it should generate a message on the alphanumeric display screen 26 and whether one of the LCD elements compre- hensive v LCD computer monitor 124 should be energized.
The operating system stored in read only memory device 218 associated with the 8085 microprocessor 210 will recognize the signal as an error message and point to the beginning address of the fault up-strokes table in the ROM language chip 220 or 221. An "offset" will be added to this address corresponding to the designator for this fault and the 8085 microprocessor will move a series of bytes corresponding to this fault into its RAM storage 222. the first byte of this message will indicate that one of the liquid crystal elements comprising the liquid-crystal monitor 24 is activated . The next eight bytes indicate which of the liquid crystal elements to be energized and whether the 'one or more of the liquid crystal elements should be energized in a continuous or blinking mode. When the left front door is open, the item labeled (e) in FIG. 5 energized.
A particular of the bits comprising the first four bytes in this eight bitgruppesekvens set while all other bytes will be all zeros. If the LCD element (e) is to remain energized continuously, the same corresponding bit will be set in the remaining four bytes of this sequence of eight bytes. These bytes are sent selectively to the graphical LCD interface 226 in series (see FIG. 11) so that the output pin of the serial-to-shunt shift register 228 corresponding to this front-left door LCD segment (e) is energized by successive clock pulses by the coupling pin 31 of this shift register. If the left-front-door LCD element to blink on and off, alternating ones and zeros ejected from this staple of the shift register to cause the energized element remains energized for a selected period of time and then be done without power on an alternating way to bring the item (s) to flash on and off.
► In the ROM module 220 is also stored a message (a series of 40 bytes) to be sent to the 8031 microprocessor 212. This message will be sequentially transferred to the 8031 microprocessor along the nine bit output bus 238 coupling the 8085 microprocessor 210 with the 8031 microprocessor. 8031 microprocessor will save this entire message in its own internal RAM in · '' 23 rooms, so that an operating system stored in the 8031 ROM chip 272 can transform the modified ASCII message to a sequence of the bit groups for selective activation of single points of the 40 character dot matrix. According to FIG. 4 is the first visible letter compre- hensive * a message regarding the open door letter L that will be sent from 8085- to 8031-microprocessor. 8031 operation system will include a conversion technique for converting the modified ASCII representation of the letter L into a nine bitgruppesekvens for transmission to the four shift registers 260- 263 to energize the appropriate dot pattern. In the present scheme, only the low four order bits comprising these bytes are loaded so that for each memory write cycle to the memory 258 are stored data regarding four pixel locations in the shift registers 260-263. After nine memory write cycles have all thirty to five pixel locations stored in these shift registers and as long as 8031 microprocessor correctly hold an appropriate f, of the 40 matrices comprising the alphanumeric display screen active, the letter (L) will be showcased in a correct position. While book rod (L) displayed in 180 microseconds becomes the dot pattern for (E) in the word "LEFT" loaded by the 8031 microprocessor through the shift registers 260-263.
8031 microprocessor 212 continues to monitor show the alphanumeric message "LEFT FRONTFØR OPEN" ( "LEFT FRONT DOOR OPEN") until 8085 microprocessor receives an indication from the master device 112 that the door has been closed. This screen display is carried out by continuous signal refurbish the computer monitor 26 until 8031 microprocessor receives an interrupt from the 8085 microprocessor. Monitor Console remote unit 125 will eventually be instructed from the master device 112 to display a different status and / or error. In this way, information is continually updated for a user interacting with the copying machine 10.
. By utilizing non-volatile storage to define the language and typeface incidence on the alphanumeric display screen beguns- "tiger screen's flexibility. By replacing a different ROM chip 220 in the storage room of 8085 microprocessor is. it is possible to use the same Error, status and program code designating receptors to display messages and to impel the user in different languages. A switch on the front panel allows language-read memory (220 or 221) are selectively switched over from one piece to a 24 second, allowing copying machine 10 are double language in their ability to communicate information to the user. For example, the switch thus · one position bringing a first read only memory 220 containing English messages to be accessed by the microprocessor and when connected to a different setting, accessed another read only memory 221 containing French messages.
Both storage will respond to the same designator, but will differ from each other with respect to the stored messages. On a similar way, the operating system for the 8031 microprocessor can easily be changed so that when data is transmitted along a nine bit double-chained bus between 8085- and 8031-microprocessor, a given data piece cause the different number of elements comprising a 5 x 7 point ( matrix) is energized.
As indicated above, the liquid-crystal data display 24 also flexible as more kopieringsmaskinkon-configurations can be used without changing the detour of data takes-l 'but or display. One only needs to place a different overlay over your computer screen so that copying machine fr outline, the user is presented to, is different for different configurations. However, it is also necessary that the 8085 microprocessor never energize liquid krystallele segments corresponding to components not included in a particular machine structure utilized. This can be arranged easily during an initialization which hove control unit 112 notifies the 8085 microprocessor 210 of the configuration control unit works with.
The present display unit has been described fairly extensively in the foregoing. It dared however be appreciated that the display panel can be subjected to certain modifications, variations or changes in the constructive structure. Although the alphanumeric display screen 26 thus for example is described as being mixed-dried, then loaded with characters and then displayed screen, could characters. be flashed or scrolled. The application of the display panel need not be limited to convey information to the user but ► can be used in display of diagnostic information for use by the technical repetition (tech rep.). All such modifications and / or changes as fall within the scope of the appended claims, is the subject of protection.
