Xerographic copier display panel

[Detailed Description of the Invention]

(Field of an invention) Especially this invention tells the state of a copy device to a user about the Xerographic copy device, and it relates to the display panel to which the interaction of a user and a copy device is urged. (Conventional technology) The Xerographic printing equipment used for operation of zerography has also progressed as the art of the Xerographic copy progresses. The present Xerographic copy device can make a double-sided copy automatically from a double-sided manuscript, and can carry out the stack of the copy Set into which the number of requests was classified automatically into Trey Deguchi. Since a different Ivy copy option is applicable to the same fundamental Xerographic printing equipment, While equipping the re-circulation manuscript handling machine which passes a platen in one copy device and to which it makes it move an original manuscript automatically, only a platen and a platen cover are provided in another copy device, and a user Set one manuscript [ one ] and can also copy it. If such various options are used, the user can satisfy each one of copy needs by the most efficient expenses. Some convenient features which easy-ize the interaction of a user and a copy device are also already used. For example, an automatic billing device tells automatically Jiyubu about which Kula Yingde is performed with the copy device, or the copy number of sheets like which the Jiyubu needs to a user. Intermediary To have [ as ] in which the user can treat a copy device much more efficiently and highly by in addition to this the convenient feature being added to the Xerographic copy device. Studying the method of diagnosing and repairing it according to ergonomics when a simple operator studies operation of a copy device or failure occurs during operation has also been easy-ized. Training on such use and/or diagnosis of a copy device are complicated with a natural thing with the advancement of a device. If it appears in the copy device of different Ivy composition and says after an operator touches only one sort of copy devices, the tendency which applies the diagnostic procedure of not being suitable to a new model will also arise. Although a user is told about the state of a copy device, and failure or alarm is carried out, the character number display is already used. For example, "please wait for a while" (Please Wait), [ "standby (Standby)" and ] Description of "the completion (Ready) of preparation", "put in a manuscript (Insert Documents) in" in, "choose copy number of sheets (Select Number of Copies)", etc. is used for telling the state of a copy device, and operation to a user. In the same display unit, a character number error code for a user to refer to the flip chart which gives directions about how to correct various kinds of problems which arose during operation of a copy device, and/or failure also occurs. Although not put more nearly yet in practical use by the character number display, the graphic display is also already proposed as a method of giving the information about the state of a copy device to a user further. These graphic displays, i.e., icon (icon), express the composition of a copy device in graph, and it notifies a user of whether cautions and/or maintenance are alternatively required for which portions of Use and a copy device in the element which can be energized. For example, with the copy device provided with the re-circulation manuscript handling machine, the icon of the manuscript handling machine positioned relatively to other portions of a copy device lights up, and it teaches a user Jam generating all over the paper circulation way in a manuscript handling machine. Especially when this kind of display tends to be combined with a character number message and tends to make a user recognize the source in question, it is effective. As mentioned above, a user requires that a copy device can be constituted according to each one of needs, without changing the basic composition of Xerographic printing equipment. Therefore, ergonomics faces the problem that the state about a copy device and/or failure information which comprise many different Ivy methods must be displayed. This problem with which a copy device meets becomes further much more complicated, when a copy device is used in the field in which a different Ivy language is spoken. A character number display suitable for the country which speaks English stops for example, being suitable in the country by which only Spanish is spoken. In the area (for example, Quebec district) where most residents speak different Ivy 2 language, the copy device which can be transmitted in two languages is needed. Therefore, an engineer faces the problem whether to design the synthetic system which can respond to whether it is made to perform another display for every position on the composition of each copy device, and geography or the composition of a copy device, and all the possibilities of language enough. (Outline of an invention) This invention relates to the method and device for giving a user the state information of a copy device. The display of the present invention functions to the composition of various kinds of Xerographic copy devices, and it can be easily changed so that character number information can be given in various kinds of languages. The interaction of the In addition, display is carried out to the electronics circuit of others in a copy device, and it has a programmable controller which monitors the state of a copy device and indicates to a user the present condition voice of the copy device which is operating by updating. The display panel by the present invention contains the message generating panel which has a character generator in which an address is possible in each of a large number which are energized and whose viewing is attained. A display panel contains the liquid crystal display which has further a pattern of the element corresponding to each component part of the copy device which can be energized. A circuit is connected to both a liquid crystal display and a message generating panel, energization of the visible message given by a message generating panel and a liquid crystal element is made to collaborate, and the user who is gazing at the panel is told about the state of a copy device. Overlay showing the composition of a specific copy device is provided. This overlay will be changed if the option of a copy device changes. If overlay showing the composition of a specific copy device is used, a single liquid crystal display can be used to each composition of many copy devices. This liquid crystal display displays roughly each component part of copy devices, such as a platen, a paper tray, Trey Deguchi, and a finish station. the desirable example of the present invention -- a liquid crystal display -- blink or the letter of continuation -- it has an element (a suddenly large number is also possible) which is turned on in one of the modes and which can energize 30 or more pieces. It exercises with a liquid crystal display and the message generating panel which comprises the vacuum fluorescence type display which can display 40 character number characters operates in the desirable example of the present invention. Each character number character comprises the dot-matrix display of 5x7, and if energized with the controller connected to this, it will display a specific character. The specific font for a display is stored in the memory of a controller, and it is stored in ROM memory A tip of fixity in the desirable example. If this is changed into another memory, a different Ivy font, i.e., a language, can be easily displayed on a character generating panel. Interlocking operation is carried out and character and liquid crystal both displays update the information about the state of a copy device to a user. The programmable unit which performs display operation is continuously updated by another programmable unit about the state of a copy device. The programmable unit of this latter has connected with a plurality of sensors or the transducer arranged through the whole copy device. For example, the sensor formed into the main paper tray detects the paper piece in the tray, and a paper tray sends a signal to empty to a main processor at the time of Noodle. Subsequently, it directs that a paper tray is empty to the processor which the main processor makes energize a display panel. According to this, the 2nd programmable unit displays a message on a character message generating means, and displays what a paper should be put into a paper tray for. Simultaneously, the 2nd controller also energizes a liquid crystal display, the liquid crystal element of relevance is energized, and it is told to a user that cautions are turned to a paper tray. This liquid crystal element is constituted so that a paper tray may be expressed in graph, receives the schematic structure figure of the Oba tray, i.e., a copy device, and is located relatively, and the user is made to understand easily where that paper tray is. (Explanation of an example) Probably, it will be clear from the above that one object and advantage of the present invention are on the point which unifies the newest state updated to the user of a character number type and a graph type copy device. Probably, the other objects, advantages, and the features of the present invention will be clear from detailed explanation of the following related with the desirable example of the present invention which referred to the attached drawing. Reference of a drawing, especially Drawing 1 has shown copy device 10 suitable for creating the Xerographic copy from an original manuscript. Copy device 10 has housing 12 with smart appearance, and covers each component part of the copy device explained below with reference to other drawings. Copy device 10 of illustration does not contain an automatic manuscript handling machine, although a platen and a platen cover are included. Intermediary To have [ as ] which can insert in up to a platen the original manuscript which a hinge stop is carried out and is copied so that a user can move platen cover 14 up and down. Copy device 10 is further provided with sorter 16, and copy Set of paginal order is obtained by this about a plurality of original manuscripts. A user chooses the size of the copy which should be created, contrast, and number of sheets via control panel 18, and he specifies the creation methods (two or more copies etc.) of a copy. The button for starting a copy function is provided on panel 18. It is used for a user performing a correction measure, when display panel 20 tells a user about the state of copy device 10 and failure arises in operation of a copy device. Display panel 20 has flip chart 22, LCD display 24, character number display 26, and power button 27. The present invention relates to the conjoint action of LCD display 24 and character number display 26, When a user reads the situation of a copy device efficiently, failure arises and it is more complicated than what tells a user about it and the command which should be given can display on LCD and character number displays 24 and 26 easily, it is in a user enabling it to refer to flip chart 22. When the user is going to operate copy device 10, LCD display 24 and character number display 26 are both blank, and nothing can display them until a user pushes power button 27 and energizes the power supply in copy device 10. If a power supply is switched on, a message appears on character number display 26 "a Wait term (Standby)", and it directs to be in the state where a copy device can still be used. when the Xerographic copy creation preparation of copy device 10 is completed, character number display 26 shows the "completion of copy preparation (Ready To Make Copies)" message -- a user -- preparation of copy device 10 of operation -- ready Ivy -- things are told. Many of component parts used to create the Xerographic copy are shown in Drawing 2 in diagram. Electrophotography device 10 of illustration uses for the surface belt 28 which has an optical conductivity side so that clearly from Drawing 2. Belt 28 moves in the direction of arrow 30, and it advances the continuation portion of an optical conductivity side through each processing station by which Along allocation was carried out to a belt. First, a part of optical conductivity surface passes through electrification station A. At electrification station A, the corona generator roughly shown by number 32 is uniformly charged on substance in comparatively high potential in the optical conductivity surface. Next, the electrification portion of the optical conductivity surface goes to image formation station B. At image formation station B, the manuscript handling device roughly shown by number 34 places original manuscript 36 upside down, and positions it on exposure system 38. However, unlike the copy device shown in Drawing 1, notice Drawing 2 about the point containing the manuscript handling device here. Of course, display panel 20 functions with any composition. The exposure system which showed the whole by number 38 contains lamp 40 which illuminates manuscript 36 located on transparent platen 42. the light reflected from manuscript 36 -- lens 44 -- a connoisseur -- intermediary transmission is carried out. Lens 44 connects the light figure of original manuscript 36 to up to the electrification portion of the optical conductivity surface of belt 28, and removes the electric charge of the portion alternatively. As a result, an electrostatic latent image is recorded on the optical conductivity surface, and this corresponds with the information field included in the original manuscript. Subsequently, belt 28 advances the electrostatic latent image recorded on the optical conductivity surface to development station C. Platen 42 is arranged so that the magnification of the original manuscript which is attached movable, and is moved and copied can be adjusted. Lens 44 moves synchronizing with platen 42, and makes the light figure of original manuscript 36 connect to the electrification portion of the optical conductivity surface of belt 28. Documents handling device 34 sends a manuscript one by one from the manuscript stack placed by the usual paginal order into the manuscript stack maintenance tray by the operator. A manuscript is sent to platen 42 one after another from a maintenance tray. A documents handling device circulates a manuscript, is held on a tray, and is returned to a To stack. Under the present circumstances, as for a documents handling device, it is preferred to send the manuscript which comprises the various sizes and thickness include the information which should be copied one by one in in-series. although the manuscript handling device was explained above, an original manuscript may be put by hand on up to a platen instead of such a manuscript handling device -- a person skilled in the art -- an intermediary -- probably, it will be clear. That is, in the printer which does not contain a manuscript handling device, an original manuscript is Set(ed) by hand (see the copy device of Drawing 1). If Drawing 2 is continued and referred to, at development station C, a pair of magnetic brush developing rollers roughly shown by numbers 48 and 50 will contact development material to an electrostatic latent image. An electrostatic latent image draws a toner particle from the career grain of development material, and forms an image on the optical conductivity surface of belt 28 in the end of toner powder. As for belt 28, development of the electrostatic latent image recorded on the optical conductivity surface of belt 28 will carry forward an image to transfer station D in the end of toner powder. At transfer station D, it is moved so that a copy paper may accomplish an image and transfer relations in the end of toner powder. Transfer station D contains corona generator 52 which makes ion spray to the back side of a copy paper. To a copy paper, this ion draws the image in the end of toner powder from the optical conductivity surface of belt 28. Conveyor 54 carries forward a paper to fixing Station E after transfer. the copy paper was chosen among trays 56 and 58 -- while -- from -- it is sent to paper course 59 and also transfer station D. Fixing station E fixes a transfer powder image to up to a copy paper eternally by this including a fixing assembly assembly. As for a fixing assembly assembly, it is preferred that heating fixing roller 62 and backup roller 64 are included. A paper passes through between fixing roller 62 and backup rollers 64 so that a powder image may contact to fixing roller 62. Thereby, a powder image is eternally fixed to up to a paper. A paper is conveyed after fixing to gate 68 where conveyor 66 functions as a reversal selector. According to the position of gate 68, a copy paper is diverted to the direction of paper reversal machine 70, or bypasses paper reversal machine 70, and is directly sent to 2nd determination gate 72. Therefore, by the time the copy paper which bypasses reversal machine 70 results to gate 72, it will revolve the 90-degree corner in a paper course. In order that gate 72 may consider a paper as upward arrangement, the image side in which it was transferred and established turns to a top. If reversal course 70 is chosen, direction will become reverse and the field printed at the end will face downward. 2nd determination gate 72 is diverted to the course which makes a paper turn on Trey Deguchi 74 directly, or carries a paper with the 3rd determination gate 76 To. Gate 76 takes out a paper out of a copy device as it is, without making it reversed, or sends a paper to double type reversal roll 78. Reversal roll 78 reverses the paper which should carry out a double type copy according to direction of gate 76, and it carries out a stack into double type tray 80. the paper which double type tray 80 is already printed on one side, and then should print an image on the side opposite to, i.e., the paper which carries out a double type copy, -- intermediate storage -- or buffer storage is carried out. A paper reversal operation of reversal roll 78 places a stack into double type tray 80 upside down in an order that buffer Set of the paper was copied. In order to perform a double type copy, the paper by which the single entry copy was carried out returns to transfer station D one by one with bottom conveyance machine 82 at the point in tray 80, and an image is transferred there in the end of toner powder at the side opposite to a paper. Conveyors 84 and 86 make a course follow a Along paper, and this reverses a paper. However, from double type tray 80, since the lowest paper is taken out, it is positioned so that a right, i.e., blank paper, copy paper side may contact belt 28, and an image is transferred there at transfer station D the toner powder end on a belt. subsequently, the course as the paper in which the single entry copy of the point was carried out in which a double type copy paper is the same -- a connoisseur -- it is taken out by the user after a stack is carried out into intermediary Sent and tray 74. If it returns to operation of a printer once again, after a copy paper is separated from the optical conductivity surface of belt 28, on belt 28, a certain amount of remains particles will certainly adhere and remain. These remains particles are removed from the optical conductivity surface of a belt at cleaning station F. Cleaning station F contains brush 88 attached so that it might rotate, while contacting the optical conductivity surface of belt 28. These particles are removed from the optical conductivity surface of belt 28 by contact rotation of brush 88. Before a discharge lamp (not shown) irradiating with light on the optical conductivity surface after this cleaning and performing electrification for the following image formation cycles, a remains static electricity electric charge is distributed. The function of each part of the 2nd figure which constitutes copy device 10 is controlled and monitored by the electronics subsystem (Drawing 3) which comprises many program type controllers linked to the main central processor 112. Interface 114 between control panel 20 and the main processor 112 tells the input given by users, such as number of sheets of a copy, to processor 112. The main processor 112 performs the actuating system stored in the main memory unit 116 according to the input from a user. The algorithm in the main memory 116 connects the main processor 112 to many remote electronics units 120~125 used for a monitor and control of Along and a copy device into transmission bus 118. Unit 120~125 changes with composition of a copy device, and the Drawing 3 side only shows typical one out of the electronic subsystems of possible a large number. Each unit 120~125 is provided with the memory (RAM and ROM) and auxiliary circuit of attachment besides an original microprocessor. LCD and character number both displays 24 and 26 are electrically connected to display table remote unit 125. Display table remote unit 125 receives state information, failure information, or programmed control information from the main processor 112, displays a suitable message on character number display 26, and also if required, it energizes one of many liquid crystal segments on LDC display 24. Character number display 26 and liquid crystal display 24 are shown intelligibly for Drawing 4 which is an enlarged drawing of the front panel. Liquid crystal display 24 is attached right above character number display 26, and is located in the flip 22 side so that clearly from a figure. Character number display 26 comprises the vacuum fluorescent tube which generates the message which is help [ user ]. A maximum of 40 characters are formed by the dot-matrix pattern of 5x7, respectively, and each 35 A pot which constitutes 5x7 dot matrices is energized independently, respectively. If the dot matrix of 5x7 is used, change not only with the Roman alphabet for giving English information but an easy font suitable for giving a message in another language which, on the whole, needs different Ivy character Set can also be hung down. Liquid crystal display 24 located right above the character number display helps correcting it, when a user does an interaction to a copy device or failure arises including various kinds of liquid crystal segments at the time of operation. Display 24 is a graph-like imitation type display, and the composition of the copy device of treatment intermediary To have specification [ a user ] is drawn on the screen. This schematic diagram has been independent of a liquid crystal display, and is changed according to the composition of a copy device. while the front door of left-hand side of the copy device is open and a liquid crystal element shows that the door is energized in the example shown in Drawing 4 -- the message on character number display 26 -- a forward left side door -- Open to release -- a certain thing is told. Next, the pattern of liquid crystal element a~E arranged on the liquid crystal display is shown in Drawing 5. The 1st next table shows the component parts or the state which each element under arrangement expresses.

[Table]

[Table]

For a person skilled in the art, if the element of the above-mentioned table is seen, the composition of each copy device does not contain all the elements of the 1st table clearly. For example, the element relevant to Stacker with the copy device which has one sorter like the example of Drawing 4 is unnecessary. However, it is a role of the control electronics in display table remote unit 125 that liquid crystal display 24 distinguishes the composition of a copy device, and energizes only the required element under multiplex element display including all the elements in front. Each liquid crystal under display is connected to each connector via an electric conduction way at the bottom of a display. Display 24 is put by this connector to a socket of a display lower part. When a specific electric conduction way is energized by a voltage signal, the segment linked to each connector is energized and some displays come to appear. Probably, a specific element does not need to explain the details about operation of a liquid crystal about how it displays in a display here, since they are detailed in literature. An example of the display shown in Drawing 5 is the special order display which these people designed and Ohio 44236, Hudson, and the crystalloid electronics company of P.O.Box628 manufactured. If it explains briefly, the glass layer of two sheets which liquid crystal display 24 is opposite-Contact(ed) mutually, and forms stratified sheet 130 is comprised, and sheet 130 is supported by front support 132 and back support 134 which limit this. These stratified sheets are constituted from the necessity of enabling it to view the liquid crystal segment formed in the center between the sheets of two sheets by polarization material. Fluorescence pipe 138 (the 6A,B [ 6 ] figure) irradiates with light through chamber 140 which is surrounded in reflective surface 142 which comprises an ABS white plastic, and is located behind a display. If liquid crystal element a~E is in a de-energizing state, only blue light will reflect with the front and back light polarizer in reflective surface 142, and it will reach a user's eyes. however -- if one of the polarization elements of a liquid crystal is energized, white light will reflect in reflective surface 142 with combination with the combination effect of the polarization segment of three sheets, i.e., the polarization layer of front and the rear surface, and the liquid crystal element of the center which polarized electrically -- the energization segment of a liquid crystal -- a connoisseur -- an intermediary user is reached. Therefore, since white light will pass the segment if one with a suitable liquid crystal is energized by the signal from display table remote unit 125, viewing becomes possible. This segment is surrounded by the blue side. Of course, the liquid crystal etc. of coloring which made white the background are possible also for the display design of those other than this. It is good as for coloring in both a background and a liquid crystal. In a coloring liquid crystal, the color is peculiar to the material of a liquid crystal only using one light polarizer. Although a coloring liquid crystal is manufactured, diazo dye of dichromatic dye can also be used. If the energization signal from display table remote unit 125 is a letter of a direct current so that clearly [ a person skilled in the art ], a liquid crystal segment will receive damage. For this reason, these liquid crystals whose viewing is enabled are energized by a 42-Hz signal rather than the signal of the letter of continuation. When blinking a liquid crystal, it is energized by the signal of per second 42 cycles, and on the frequency of an exchange signal, it was de-energized between fixed OFF cycles, and a liquid crystal is back-energized. Printing circuit board 144 which accomplishes a part of display table remote unit 125 is equipped with fluorescence pipe 138, reflective surface 142, and a liquid crystal display, respectively. After stuffing stratified sheet 130 into socket 146, front attachment bracket 148 is positioned on a display, and a display is held to a prescribed position. It has a slot, a screw OFF connector (not shown) is pushed in through this hole, and bracket 148 is thrust into the main part of a display. If light pressure is applied to the top part of a bracket, a stratified sheet will be automatically deflected to three attachment mailboxes 158~160. Since a stratified sheet will be firmly held by this in a predetermined position if a bracket is bound tight, electric connection required to energize a liquid crystal element is secured. As mentioned above, a guide is given to a user, when [ in which a user includes the schematic structure figure of a treatment intermediary To have copy device ] overlay 149 which can be viewed is placed on stratified sheet 130 and energizes liquid crystal element a~E in display table remote unit 125 eternally. eight kinds of different Ivy overlay -- the -- it is shown in 7A~7H figure. Once the buyer subtenancy ON person of a copy device opts for the specific composition of the device, It becomes [ being fixed with as on that display, and ] until, it is equipped with on liquid crystal display 24 and the composition of a copy device is changed into the overlay corresponding to this composition carrying out position Agreement of it to stratified sheet 130. [ no tool ] the -- as shown in 7A~7H figure, general overlay includes the schematic structure figure of the copy device surrounded by the transparent piece made from a plastic fixed with a plurality of mounting tabs 150~153. These three mounting tabs limit consistency hole 154~156 which carries out position Agreement of the schematic diagram of a copy device to the liquid crystal element given with stratified sheet 130. When display 24 is equipped with overlay 149 according to the composition of the specific copy device, these three consistency holes 154~156 engage with three corresponding consistency attachment mailboxes 158~160 (the refer to 6A andB [ 6 ] figure) provided in the attachment bracket of the display. the -- when the composition of a copy device differs so that he can understand easily from 7A~7H figure, using different Ivy overlay, on the other hand, with respect to the composition of a copy device, there is no liquid crystal display 24 very thing, and it contains all the element a~E which can be energized. Although stated above, it is a role of control electronics for the liquid crystal element which is not contained in the composition of a copy device to be turned on, and to make it make catoptric light penetrate. Display table remote unit 125 (Drawing 3) has two microprocessors 210,212 (Drawing 8th [ the ] and 9). The first processor 210 comprises Intel8085 microprocessor linked to the main processor 112. Display table remote unit 125 is changed into a parallel transmission signal for this to receive the signal from the main processor 112 which appears on transmission bus 118 in the form of the letter transmission packet of a direct current by the data / address bus 216 of 8085, further including very large scale integration 214 for special transmission. Transmission A tip 214 is an integrated circuit of the special order which carries out the Ethernet protocol which these people developed, and the same protocol for transmission. The serial transmission currently used in each processing unit of the latest copy device resembles the packet transmission method, The priority of message transfer is decided, and in order for each of processor unit 120~125 to send a message to another remote unit, a command must be obtained from transmission bus 118. It is changed into a parallel signal so that transmission A tip 214 may receive the packet of information here and this may be received by microprocessor 210 of 8085. a serial transmission line -- Along -- a general signal tells to 8085 the failure which arose during the state of a copy device, or its operation. The function of 8085 interprets the transmission signal which appears on its data / address bus 216, and displays the message of relevance, and there is in energizing some LCD elements under display 24 according to a situation. With the system used by the present invention, about 130 different Ivy messages are Sent alongs to an in-series transmission line in 8085 in [ the main processor 112 to ] display table remote unit 125. 8085 microprocessors 210 are provided with four memory units 218,220,221,222. 8K which connected the first three memory units 218,220,221 to the data/address bus of 8085 directly ROM memory A tip is comprised. As for these ROM A tip 218,220,221, a person skilled in the art can do only reading by 8085 clearly. First ROM A tip 218 has memorized among three the operating system of 8085 which interprets the in-series transmission message transmitted from the main processor 112. Other two ROM A tip 220,221 contain the typical message memorized in nonvolatile memory for the display in character number display 26. Since 8085 microprocessors 210 need a certain amount of memory location which can write in data when displaying this message, 2K RAM1 Nitto 222 is also contained in others. 8085 microprocessors 210 are programmed to perform the input and output of almost all according to a memory map type input-and-output method. Although it is clear to a person skilled in the art, in operation of this method, it is necessary to generate many Enele signals so that various kinds of circuits can read data in Sending and its bus for data to the data bus of 8085. Generating of these Enele signals is performed by address decode logic circuit 224. As shown in Drawing 8, this address decode logic circuit 224 generates seven sorts of ROM decoding signals, two sorts of RAM decoding signals, the signal that decodes transmission A tip 214, and five sorts of special input-and-output decoding signals. If the power supply to a copy device is switched on, the operating system memorized by 1st ROM A tip 218 will perform many initialization steps first, before energizing LCD display 24 or character number display 26. In this initialization stage, the composition of a copy device is told from the main processor 112 to display unit 125. Next, an operating system monitors the message packet from the main processor, and receipt Ivy information mistakes it, and it determines information, state information, and what is called program information. an example of an error message -- front door 13 of housing 12 -- if open -- when -- It was, as for an example of a state message, preparation of a copy device of an example of a It was and program mode message is [ when ] It was when, when a user decides adjustment of copy contrast to be ready Ivy and needs it immediately. The subset of an error message is what is called a dual fault (double error) code that can be related to the composition of two copy devices. When this code exists, the processor must opt for the composition of a copy device first, and must display the message of relevance after that. Each message has an original directions number and 8085 microprocessors enable it to have found the message of relevance by this directions number. That determination which should display which message about the directions number of each message is Using(ed) in the search table contained in either of 8K ROM A tip 220,221. ; in which these 8K language ROM has the following three different Ivy search tables, respectively -- the table for error messages, a state / table for program mode messages, and the table for double error messages. After determining which message to be required for 8085, the search table of relevance is pointed out, a number equal to the directions number of a message is offset, and the message which exists subsequently to the location is put in from one side of 8K ROM to reading intermediary RAM memory space 222. The message for every directions number comprises 9 bytes of header, 40, or 80 bytes of message. The byte of the beginning of a 9-byte header directs whether LCD under display should be energized. Which LCD's being energized the following eight bytes and these LCD direct to blink or whether the light is switched on continuously. Each byte in remainder 40 (or 80) byte corresponds to each character of the character number display for 40 characters. Eight A bit each bytes in this portion of a message cope with the characteristic energization form for 35 A pot which comprises a vacuum fluorescence character, respectively. If ROM is changed, a message can be displayed in a language with various alphabet fonts, such as Russian and katakana. That is, the generating of the message by the search table method can make it possible to use a different Ivy language only by changing simply the search table of ROM accessed for a message display of 8085. Interface circuit 226 (Drawing 11) for energizing the specific liquid crystal under display 24 is directly connected to the data / address bus 216 of 8085. This LCD interface comprises two entrance cables 232,234 from direct / average shift register 228, buffer 230, and address code logic circuit 224. Buffer 230 is pin 3 and it has connected it to line 0 of 8085 data buses directly. When buffer enabling is Set(ed) by pin 11 of buffer 230, the data which appeared in pin 3 is Latchch(ed) by buffer 230 as an output of pin 2. The output of pin 2 is inputted into pin 34 of direct / average shift register 228 following this Latchch step. Since the enabling signal for buffer 230 functions also as a clock signal direct / for average shift register 228 as shown in Drawing 11 again, Whenever a data bit is Latchch(ed) by launching buffer 230, the clock input of this is carried out simultaneously to the time of the in-series input in pin 34 of a shift register. Like illustration, it is connected to pin 2 of a shift register, and the 2nd entrance cable 234 gives the enabling signal for shift registers. Direct / average shift register 228 has a series of 32 output pins, and these pins are directly connected to the LCD segment on display 24. If a sequential load is carried out to shift register 228, in-series data will answer the 42-cycle output control signal included in pin 31 of shift register 228, and will be used as an energization signal for a LCD display. Since the clock cycle of 8085 is quick enough, loading is possible for a shift register between the continuous pulses of a 42-Hz output signal. Therefore, although the energization form of LCD is changed, 8085 microprocessors 210 energize load input signal 234 of a shift register, send in-series data into a shift register, and, subsequently should just wait for the next signal of an output signal 42 cycles. Thus, microprocessor 210 energized the specific LCD segment and is provided with the capability to make the segment turn on on display 24. For example, if it repeats energizing a segment between 21 output cycles, and de-energizing between 21 output cycles by turns, the selected LCD segment can be blinked for every second. Next, if it returns to Drawing 8, 8085 microprocessors 210 will be connected to 9 A bit parallel transmission channel 238 to Along 8031 microprocessor 212 (the 9A,B [ 9 ] figure), The information which should be displayed on character number display 26 via this channel is directed to 8031 microprocessors 212. 8 A bit are combined to data bus 240 of data buses 216-8031 of 8085 via a pair of data buffers 242,244 (theB [ 9 ] figure) among 9 A bit on parallel transmission channel 238. When data communications begin and 8085 microprocessors desire data communications to 8031 microprocessors, the 1st buffer 242 receives CLK input 243 from address decode logic circuit 224. When this signal 243 is received, flip flop 245 applies interruption to 8031 with entrance cable 248, and makes 8031 microprocessors read the data on 9 bit-data channels. 1 A bit goes into entrance cable 247 in port P1.4 of Along 8031 among 9 A bit. In the interruption routine of 8031, the contents of 8 A bit buffer 242 are first read for this 1 A bit after reading Ivy, and that byte is remembered to one of the 8031 internal registers (one of the 128). Whenever 8031 microprocessors 212 read data in buffer 242, signal 250 which enables the output of a buffer is generated by 8031 address decode circuits 252. This signal 250 also resets flip flop 245. 8031 can also be conversely returned to the data of 8 A bit via 2nd data buffer 244 to 8085 microprocessors. However, according to the present invention, it is only an Acknowledgement signal which shows that data was received from 8031 microprocessors 212 by 8085 microprocessors as for the signal sent to 8085 microprocessors 210. At the time of operation, 8085 microprocessors 210 think directions that failure occurred that the composition or the state of the specific copy device was acquired from the main controller. and the program 8085 was remembered to be by the ROM A tip for operating systems -- therefore, a state and/or failure are analyzed and it is decided which message should be displayed on character number display 26. Subsequently, this message is sent to 8085 to 8031 microprocessors, and is memorized by that internal RAM space. Next, the transmission protocol used for transmission between 8031 and 8085 is explained. This protocol sends information in the form of the unit called a packet. A packet is a capsule of the information which comprises a header byte and a data byte sequence. A header includes the command field of 4 A bit which describe the contents of the message. Three A bit check sums are transmitted by both Acknowledgements (ACK) returned when the message packet itself and a packet are received correctly. If ACK is not received within 1~2 ms after transmission, a packet will be again sent from 8085. A header other than packet length and a check sum contains the sequence number of 1 A bit. The 9th A bit input included in port 1.4 is used as a flag which distinguishes a header and a data byte. If this A bit is Set(ed), it means that this has a header byte in the byte portion of that port. It is considered that this state is the start of a packet flag. Whenever a new byte is written in the port, 8031 routines interrupt. This routine reads A bit of P1.4, and after it asks for whether it is processing [ which ] of a header or data, it reads the byte portion of that port. 8031 stores the packet in the buffer until it finishes reading a number of bytes directed in the command field of the header. At this time, a receiver calculates the check sum of a message and compares it with the check sum contained in a header byte. If both check sums are in agreement, 8031 will carry out the Acknowledgement of a packet. This ACK contains the check sum and sequence number of a packet which carry out an Acknowledgement. When One byte is detected to that of the following packet before the packet of the incorrect intermediary There was case, i.e., the beginning, was completely received for the check sum, no response operation arises but a message is re-transmitted. If a receipt Ivy message is ACK, transmission of a transmitting machine will be attained again. 8031 must change the data generated in 8085 into a signal suitable for energizing character number display 26. One conversion method used by the present invention is the modification ASC display of data. Therefore, the same byte as ASC of 40 which expresses with the internal memory of 8031 microprocessors 40 character number characters which should be displayed on a display is remembered. And 8031 accesses the index table contained in the 4KROM space 272, finds 35 applicable bit patterns (nine data bytes), and displays on the dot matrix of five xeach 7 which constitutes character number display 26. display energization circuit 256 -- the -- it is roughly shown inA [ 9 ] figure in detail in Drawing 10. Circuit 256 has data Latchch 258 with four input edges linked to data bus 240 of 8031. This Latchch will be in the state which can be operated by signal 259 from 8031 address decode circuits (theA [ 9 ] figure), Latchch 4 A bit of the data which appeared on the data bus of 8031, and sends these 4 bit data to direct / average shift register 260~263. In the desirable example of the present invention, these shift registers comprise a Sprague4810A shift register, respectively. Four input edges of Latchch 258 have a corresponding outgoing end linked to one of direct / the average shift registers 260~263, respectively so that clearly from Drawing 10. These four shift registers are put mutually together, and give the output signal of 35 to 35 positions of 5x7 dot-matrix displays. A total of 40 dot matrices [ 5x7 ] which constitute a vacuum fluorescence display have mutually the corresponding matrix position by which electric connection was made. Therefore, whenever a shift register generates the control signal about a predetermined matrix position, this control signal is transmitted to all 40 matrices. However, only one character is can be viewed in fact, It is because 8031 microprocessors are controlling operation of 40 bit-shift register 266 which makes an operating state 40 character number dot matrices which can come, simultaneously constitute a character number display one by one, respectively. That is, 8031 microprocessors generate the pattern of which viewing should be made possible on display 26 by loading to shift register 260~263, and 40 matrices are made to be energized one by one via 40 bit-shift register 266. Desirable 40 beat shift register 266 comprises four Sprague 4810A shift registers connected mutually, and gives control output of a total of 40 for every dot matrix. When starting the display of the 1st character and 8031 microprocessors 212 write data in Latchch 258, data bit zero are Set(ed). The clock input of this high A bit is carried out by existence of two signals in which it results to the clock input edge of 40 bit-shift register to a shift register. Two signals occur in address decode circuit 252. Since 8031 low-Into the zero bit in the outgoing end of Latchch 258 by the following clock signal, zero are loaded to a shift register. Since the clock input of the one high A bit will be carried out in all the positions of 40 if zero are loaded, a total of 40 matrix will be in an operating state one by one. The blank of the character number display is periodically carried out by sending a signal to four blank input edges of shift register 266. This blank signal occurs by Latchch 270 which a clock is carried out with WR3 signal and transmits the data bit zero signal according to a blank signal. This Latchch 270 will also make display 26 blank, if the RST signal which arises from main controller 112 at the time of starting is received. As for the timing for every character, a display is 180microS and the blank display of 20microS continues after that. Therefore, in order to display all 40 characters, S= 8 ms of 40x200micro is required. The bit pattern for the following characters is loaded into shift register 260~263, when the last character is displayed. When failure of forward left side door 13 of copy device 10 opening suddenly occurs, it is necessary to investigate operation of display table remote unit 125. Supposing forward left side door 13 opens now, this fact will be immediately told by the input from Xerographic remote device 122 to main controller 112. if these directions are received, "forward left side door will open a centralized processing master -- One(ing) -- Pathetic"-- the signal which shows things is generated and it sends to display table remote unit 125. If this failure signal is received in display table remote unit 125, on character number display 26, it will be investigated whether one of the LCD elements which constitute [ whether a message should be displayed and or not ] LCD display 24 further should be energized, and it will be determined. The operating system memorized in ROM unit 218 corresponding to 8085 microprocessors 210 recognizes the signal as a failure message, and directs the start address of the failure search table contained in ROM language A tip 220 or 221. After offsetting each other to this address according to the directions number of failure, 8085 move a series of bytes according to that failure to RAM memory space 222. The byte of the beginning of a message directs the fact that one of the liquid crystal elements which constitute liquid crystal display 24 should be energized. as for the following eight bytes, which liquid crystal element should be energized -- it is -- and one or more liquid crystal Elemant -- the letter of continuation, or the letter of blink -- it is directed by which it should be energized. A forward left side door opens, and when it is One by one, the element shown all over [ e ] the 5th figure must be energized. Therefore, one with specific A bit which constitutes 4 bytes in an 8-byte sequence of the beginning is Set(ed), and all other bytes are made into zero. The same corresponding A bit is Set(ed) in remaining 4 bytes in an 8-byte sequence to energize LCD element e continuously. Because these bytes are transmitted to graph type LCD interface 226 (refer to the 11th figure) alternatively and in the shape of series, The output pin of direct / average shift register 228 corresponding to LCD segment e for forward left side doors is energized according to the continuous clock pulse included in pin 31 of the shift register. It repeats by turns de-energizing, after energizing the element which 1 and 0 are outputted by turns and they should energize from the pin of a shift register for a fixed time and blinks element e to blink the LCD element for forward left side doors. In ROM module 220, the message (40-byte sequence) which should be transmitted to 8031 microprocessors 212 is memorized. This message is transmitted to nine A bit output buses 238 which connect 8085 microprocessors 210 to 8031 microprocessors 212 to Along sequential 8031 microprocessor. Since 8031 microprocessors memorize this whole message in an internal RAM space, A modification ASC message is convertible for the byte sequence for energizing each point of a 40-character dot matrix alternatively by the operating system contained in 8031ROM A tip 272. In the display shown in Drawing 4, the first visible character that constitutes the message about an open door is L of the alphabet, and this is transmitted to 8085 to 8031 microprocessors. Then, the operating system of 8031 contains the conversion method for changing the modification ASC display of character L into the 9-byte sequence transmitted to four shift registers 260~263 in order to energize the dot-matrix pattern of relevance. In the display form of here, since only Order bit of four low grades which constitute these bytes is loaded, the data about four pixel positions is stored in shift register 260~263 for every memory write-in cycle to Latchch 258. All the pixel position of 35 pieces is stored into these shift registers after 9 times of memory write-in cycles, and while 8031 is continuing energizing correctly one to which 40 matrices which constitute the character number display for 40 characters correspond, character L is displayed on the position of relevance. When character L is displayed for 180 microseconds, the dot pattern of the next character E in a word "LEFT" is loaded by 8031 in shift register 260~263. In this way, 8031 microprocessors 212 continue displaying the message "LEFT FRONT DOOR OPEN" until 8085 microprocessors receive directions called closed Ivy in a door from main controller 112. This display is obtained by rewriting and (refreshing) carrying out display 26 continuously until 8031 receives interruption from 8085 microprocessors. When displaying a different Ivy state and/or a failure message, display table remote unit 125 receives the directions from the main processor 112 ultimately. Thus, information is continuously changed to the user handling copy device 10. If the non-volatile memory space which limits the language which appears on a character number display, and a font is used, the flexibility of a display will improve. If different Ivy ROM A tip 220 is substituted for the memory space between 8085 microprocessors, although a message is displayed in another language and a user is notified, the same failure, a state, and the code directions for a program can be used. If a switch is formed in the front panel and language ROM220 or 221 is alternatively switched to another side from one A tip, the capability for copy device 10 to give information to a user will serve as 2 language types. For example, if 1st ROM memory 220 that contains an English message when a switch is in the 1st position is accessed by the microprocessor and a switch switches to the 2nd position, 2nd ROM memory 221 containing a French message will be accessed shortly. Although both of the memory spaces answer to the same directions display, it differs in respect of the stored message. If the operating system for 8031 is changed easily and Along data is made similarly to transmit to 9 A bit bidirectional bus between 8085 and an 8031-car microprocessor, A different Ivy element can also be made to energize in the fixed portion of data among a plurality of elements which constitute 5x7 dot matrices. Since the composition of a display is changed and a copy device can be variously constituted without things as mentioned above, liquid crystal display 24 is also flexible. What is necessary is just to put another overlay to up to a display, in order to change the schematic diagram of the copy device shown to a user for every different Ivy composition. However, it is necessary to make it 8085 microprocessors not energize the liquid crystal element corresponding to the component part which is not contained in the composition of the copy device with which it is used in any case. This can be processed easily in the early stage where main controller 112 tells the composition made into the object of operation to 8085 microprocessors 210. In the present invention, overlay attached so that exchange was possible, and a liquid crystal display panel which has an element which can be energized about all the possible combination of a copy device and an attached device are provided separately. Therefore, it is not necessary to order a display of a copy device, respectively about each of combination of a copy device and an attached device for which each customer asks, and there is an advantage that only various kinds of overlay that can be detached and attached freely is required as easily as only one general-purpose display. The display panel of such a copy device is rich in flexibility, and effective also in reduction of manufacturing expenses. In the above, the display unit of the present invention was explained in detail. However, of course, a design variation fixed about the above-mentioned display, substitution, or modification can be given. For example, after carrying out the blank of the character number display 26, the character was loaded and it explained that it subsequently displayed, but a character may be illuminated or it may be made a scroll type. Use of a display is not restricted to the notice of information to a user, but can also be used to display the diagnostic information for an engineer. All also of such a change and/or modification are contained in the thought of the present invention indicated to the claim, and the range.
