Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an image processing/system for forming an image using one or more image forming devices based on an image signal output from an image output section of an image reading device or the like. .

[Prior art]

Conventionally, this type of image processing apparatus has been proposed for an image processing system that forms an image based on an image information signal obtained by fully optically reading a document. Since the copies had to be handled on a one-to-one basis and the reading and weaving of the original was repeated every time an image was formed, improvements in the efficiency of copying operations and operator operability were desired. It had been.

〔the purpose〕

The present invention has been made in view of one or more of the above aspects, and it is possible to completely improve the efficiency of copying operations by providing a multi-input multi-output device 1ffi to an image information storage section, and to perform multiple image formations at the same time. The aim is to provide an image system that is easier for operators to operate.

〔Example〕

The present invention will be explained below based on all the drawings. FIG. 1 is a perspective view of an overall layout of an embodiment of a processing system according to the invention. Reference numerals 1 and 2 denote readers for reading original images, and their respective signal lines are connected to a multiple input multiple output device #3 (hereinafter referred to as MIMOU). Also, 5,6

A storage/memory unit (hereinafter also referred to as MIJ) connected to the MIMOU 3 and capable of storing and outputting image information. Unlike the other devices described above, the MU4 is connected to the MIMOU 3 by two signal line cables. The above-mentioned MU4 has one cable connected to each of the above-mentioned connector parts.

In Figure 1, MIMOU 3 has 22 readers and 5 and 62 printers connected, but combinations with more or less than the above numbers are also possible, with a maximum of 4 readers and 5 printers. Up to 8 devices can be connected.

Next, using Figure 2 to Figure A6, proceed as described above.

, a multi-input multi-output device t (M I M OLJ ), a printer, etc. will be explained in detail.

FIG. 2 (at and fb) is a block diagram showing an example of the internal configuration of the reader 1. As shown in FIG. In this embodiment, in order to achieve high-speed, high-density reading, a method is used in which all two original images are read by CCI) and this is concatenated into one signal to generate a 1 rai/image signal. There is.

First, we will start with the explanation of Figure 2 (al).

Optical lens 10.11 is used to form an image of a document placed on a document table (not shown) onto C0D 12.13. The original image is sequentially scanned by an optical system (not shown), but since this glare-removal technique is a well-known technique, a detailed explanation will be omitted.

CCDs 12 and 14 convert the shading of the original image into electrical signals. This electrical signal is amplified by an amplifier circuit 14.15 and converted into a multi-value digital signal for each pixel by an analog-to-digital converter (A/1) converter 14.15.

Furthermore, the digital signal is transmitted to the shading correction circuit 18.
19: uneven light emission of the light source, uneven luminous intensity distribution of the optical system, CC
After removing shading caused by uneven sensitivity of D, the ternary digital image signals vo1-A i'g, VDl-B signals,
The signal is converted into a D2-A signal and a VD2-B signal, respectively.

Ternarization is to perform binarization using two stages of binarization levels, but there is a method that uses a constant binarization level given by the latch circuit 26 and a predetermined map using the dither ROM 24゜25.
Selectors 22 and 23 allow selection between two types of ternarization processing, a so-called dither method, which is a method using binarization levels that are periodically changed within the IJ box size. The dither method uses all binary signals to create pseudo halftones, and is widely used in facsimiles and the like.

In this embodiment 2, it is possible to obtain the optimum copy image quality by selecting a method that gives a fixed binary level for text documents, etc., and a dithering method for documents that require full gradation, such as photographs. It has become.

Furthermore, in the method of giving a fixed level, it is also possible to select to set the two levels of ternarization to the same value.

The dither RO1v124.25 includes all dither patterns sequential i1 output-t stored in the addresses given by the counter 27 that counts the number of lines in the sub-scanning direction and the counters 28 and 29 that counts the total number of pixels in the main scanning direction. .

In addition, in order to prevent the dither putter 7 from being disturbed at the joint when combining the electrical signals read by the CCI) i 2 and the CCD 13 into one line, the VC is a latch that provides preset data for the optimal count to the counter 29. A circuit 30 is connected.

This latch circuit 30 and other latch circuits in the M2 diagram are connected to the CPU bus of the CPU 38, and
38, the data is keratched. CPU: 38
operates according to a control program written in the ROM 39, and controls the entire league using L(, AM40, I10 port 41, timer circuit 42, serial circuit 43, and key display drive circuit 44).

The CPU 3 f3 performs adjustment and operation confirmation meetings based on the values set by the dip switch 46.

The key display drive circuit 44 is a circuit for scanning the key matrix of the 5-operation unit 45 and driving all display devices such as LEDs. Further, it is a circuit used to give control commands to the serial circuit 431-i, a printer, and a multi-input multi-output device, and conversely to receive all information.

The oscillation circuit 32 provides a timing signal to one of the CCDCD drive N paths for fully driving the CCLs 12 and 13 and other parts handling image signals. The oscillation signal is counted by a counter 33, and the count value is further input to a decoder 34 to generate various timings.

In the decoder 34, internal synchronization H for each l line in the sub-scanning direction
An S signal is generated and input to the selector 35. A similar synchronizing signal B[) signal (described later) sent from the printer when the printer is connected is also input to the selector 35. According to the procedure, if the pre/re is directly connected to the reader, select the BD double signal in step S9-3.
), when a multi-input multi-output device is connected to the league, the HSS overtone is automatically selected (S9-4). The selected signal is used as a synchronization signal in the sub-scanning direction as an HS8D signal. The H5BD count is also input to the color 4-ku 33 and used as a count reset signal.

The color/receiver 33 outputs the original clock of the write clock when inputting the image signal ■D1 signal and the VO2 signal to the memories 60 to 63, which will be described later, and then outputs the original clock of the write clock when inputting the image signal ■D1 signal and the VO2 signal to the memories 60 to 63, which will be described later. write clock W
It becomes a CLK signal. The rate multiplier 36 divides the frequency of the input clock signal according to the value of the control fl signal (in this embodiment, the two-way circuit 37) applied from the outside and outputs the divided clock signal. In this embodiment, it is used completely for scaling the image in the main scanning direction.

Next, the entire explanation of FIG. 2 fbl will be given.

Latch circuits 50, 51, and 52 preset and preset the write counter 53 and read counters 54 and 55, respectively.

It is generated by the K signal (described later).

The memory address signals output from the write counter 53 and read counters 54 and 55 are sent to the selectors 56 to 55.
59, either the write counter 53 or the read color/return signal 54.55 is selected 2 and applied to the memories 60 to 6'3.

The memories are a pair of memories 60, 61 and 62, 63, and when one is performing a write operation, the other makes a read operation sound.The VC realizes conversion of signal speed.

One set of memory repeats write operation and read operation for 7 lines, and during write operation, write color/return 53 times.
It operates by receiving a signal from the signal sound selectors 56 to 59 from the L read counter 54 and 55 during the read 7 operation. The repetition control of the write operation and read operation is performed by the above-mentioned HSBD signal.

The oscillation circuit 66 generates all oscillation signals that serve as reference timing during a read operation. The 4g oscillation is the video clock (
vCL) and output to a printer or the like. The control circuit 67 is a circuit for setting the write control @ to row/') by the H3BD signal from the selector 35, and controls the left merge/counter 68,
Bit war cow/ri 69 operation fee is controlled.

Rate multiplier 64. The latch circuit 65, like the rate multiplier 36 and latch circuit 37 described above, generates all signals as the read clock RCL. Also, a video enable signal VEi, which will be explained in FIG. 7, is output to a printer or the like.

The entire control circuit diagram of the retention memory unit will now be explained with reference to FIG. γ5 is a microcomputer with i(0M713, ltAM77,
It is connected to an I10 boat 78, a timer circuit 79, and a serial communication circuit 80, and the operation of each part is the same as that of the reader section, and the I10 boat 78 is connected to each selector of the memory section.

The serial communication circuit 80 is connected to the multiple input multiple output device (MI
It can be connected in parallel to the reader-side interface of MOU) 3 and the printer-side interface.

The memory section consists of memory A85 and memory B86,
Each can store image information for one A3 sheet. The original signal of the 3-value signal is A and B in the image
Since this occurs, selector 97.98 selects memory A85.
Data can be written to either memory B86.

The image signal A is written to the shift register rA82 by the video clock, and written to the memory 1JA85 in synchronization with the address generation circuit 83. Image signal B is similarly written to memory IJ B 86 through shift register IBi. Writing of the two images No. 18 is performed using a common video clock. Further, the memory address generation circuit 83 is synchronized with the video clock and the video enable signal. The video clock t input to the address generation circuit 83 is selected by the selector 81 from the MIMU
3 and the one generated by the internal generation circuit 91 are selected. As for the video enable signal inputted to the address generation file path 83, the selector 88 selects the one communicated from the MIMOU 3 and the one generated by the internal generation circuit 8γ. In addition, the VE generation circuit 87
The H5 signal generated by the selector 74 is sent to MI~10U3 instead of the BD double signal.

This address generation circuit is also used when reading from memory. Note that the writing to the memories A, B85, 86 and the start of bladder evacuation are output from the CPtJ75 via the I10 port 78.

The image information of the memo IJA, B85.86 has an address generated by the address generation circuit 83, and the image information is as follows.
The shift registers 2A and 2B89.90 output the data as serial data in synchronization with the video clock generated by the internal generation circuit 91.

The video enable generation circuit 87 is similar to the HSBD generation circuit in the reader section, and is generated at the timing shown in FIG. The generated image signal is selected by selectors 922 and 93 to be output to either A or B, and is output to either the A or B line, and is output to the image 1 aperture signal of 7 and the OR circuit 94.9.
5 is ORed and output. Also, Memo IJA, 8
Gates 72 and 73 are provided so that the OR of both outputs and the clear signal is false. Further, the selector 96 selects between the video clock communicated from the reader and the video clock generated by the internal generation circuit 91.

Finally, the multiple input multiple output device (M1 to 10U) shown in Figure 4
The entire configuration block diagram will be explained.

MIMOUloo has 4 readers 1o1~104 and 8
It fully shows how the bridges 111 to 118 of the stand are connected, and also shows the entire internal configuration.

It is composed of three types of units: 121 to 128 (hereinafter referred to as 3D) and an operation section 147.

MIMOC 120fl-j: A unit to which the readers 101 to 1o4 are connected, and has serial circuits 131 to 134 connected to the serial circuit 43 of each reader and a serial circuit 135 connected to the printers 112 to 128. The operation of these circuits is controlled by the CPU 140. Note that the CPU 140 operates according to the control program written in I(, (lv1141)2, and RAM 142.110 baud h1j3.1 connected to the CPU bus VC.
The interrupt controller 144, timer circuit 145, and key/display drive circuit 146 are used to control the entire MIMOU 100.

From the MTMOC 120, a control bus CB and an image bus IH are outputted to 5BDi21□-128 as shown.

The image bus IB is a signal bus that transmits the image signals sent from the readers 101 to 104, respectively, and the control signals of the image signals.

The control bus CB is connected to the same serial signal as the printers 111 to 118 (the printers 111 to 118 are connected to the serial circuit 1
MIMOUlo by the serial signal generated by 35
o) and SBD of I10 port 143
This is a signal bus for control signals.

In the non-embodiment 2, the command to open the substitute copy is given by the leader, who is in the relationship of jT slave with respect to the M I MU U 100 k:r'J-data Vc. For this reason, since the reader does not know when the serial signal will arrive,
The IJ 140 is configured to handle serial signals from all the readers.

On the other hand, for printer 7, M I MolJ 10
0 is in the master relationship, so one serial circuit 135 can exchange serial signals with a plurality of printers by sequentially transmitting 7 real signals every time the serial signal is exchanged.

The operation unit 147Vi and the key/display drive circuit 146vC produce the scanning of the key/matrix and the drive sound of the display.

Details of the operation section 147 will be described later.

5BD121 to 128 are ') - 1 used to output the image signal sent by Takara and take the M period of the pre/re operation. Give an explanation.

FIG. 5 is a circuit block diagram showing a typical circuit configuration example of the synchronous memory boards 5HD121-128.

Referring to FIG. 5, the selector 150 is a switching circuit for selecting all control f111 signals of the reader assigned to the CPU 14Q from among the image control signals sent from a plurality of readers.

The selected control signals are light color/re151 and V
All the address signals sent to the E counter 152 for writing image signals into the memories 171 to 178 and the select signal for memory writing are generated.

The selector 182 is a switching circuit for similarly selecting the image signal of the selected reader, and the selected image signal is input in parallel to the memories 171 to 178, and is written into the memory selected by the selectors 161 to 168. is memorized.

The write counter 151 generates all address signals for writing all the image signals into the memories 171-178, and these address signals are input to the selectors 161-168.

In the VB counter 152, a control signal line indicating one line of the image (VE multiplication signal count/count, color/eye correction is input to the decoder 153, and which memory V column of the eight memories 171 to 178 is input) A write selection <g is generated to determine whether to perform keying 7 and is input to selectors 161 to 168.

These circuits are initialized by a control signal line (V8YNC signal) sent from a connected reader indicating the start of the image. Writing to memory is performed using memory 171. Memory 172, memory 173...Memory 1
77, memory 178. Memory 171...
This is done in order as follows. ~Meanwhile, memory 111~
The reading of image No. 15 from 178 occurs when half of the entire memory is written with VCiu+i+'4 signals, i.e., non-embodiment VC? In this case, a control signal for starting reading of the 7th mark that starts when writing to the memo I 7174 is generated by the decoder 153 and input to the 13D control circuit 154.

Bl) ffilJr1 circuit 154 is
After initialization with the N Cam number, all output of the BD double signal (BD' signal) sent from the connected printer is prohibited until a control signal to start reading is received from the decoder 153. When the inhibition of output of B Di words is lifted, BD

・Do the following in order.

Oscillation 1 path 155. Control circuit 158. The left margin color/return 156 and bit counter 157 are
The illustrated league oscillation circuit 66, control circuit 67, left
It corresponds to the margin counter 68 and the bit counter 69, and has almost the same function. The difference is that a VE' signal similar to the VE multiplied signal is generated from the control circuit 158 and input to the VE counter 180.

The VE counter 180 counts all lines of the VE' signal, inputs the count value to the decoder 181, generates a read select signal indicating from which memory all lines are to be read, and inputs the signals to the hefters 161 to 168, respectively.

In selectors 161 to 168, light color/color 151
and decoder 153, or bit counter 157 and decoder 181.
Controls input into and output from memories 171 to 178.

Picture 1 group number 1- drawn out from the memories 171 to 178 is read out by selector 185, all of the picture number 1 group number 1 in the first memory is selected 2, and the signal is sent to the printer with a VD double signal.

The profit l bus CB has a latch circuit 183, an interface circuit 184, and a control side circuit 185V (no human power is required).

The latch circuit 183 latches the select sub-leg signal to the selector 150.182. This latch is configured so that the control circuit 185 monitors the control bus signal and the dip switch 18
The value set in 6 and the SBD specified by the open side 1 bus CB
This is done when the numbers match. Control between the MIMOC 120 and the SBD is performed using the dip switch 186 in this way.
This is done using the value set in n.

FIG. 6 is a block diagram showing an example of the internal configuration of the printer. The explanation will be given using FIG.

The serial line 1B from MIMOUi00 or the league is input to the serial circuit 201 and processed by CI) U2O5. CPO200Fi, tt OM 203v
c Operates according to a stored control program, 1tAM2
04, the timer circuit 202 and the I10 port 205 are used to control the entire printer.

The input interface 2071-1 performs input processing such as a sensor signal for detecting paper in the printer.

The drive circuit 208 includes a 1-! drive circuit for driving a motor (not shown), a high voltage transformer, etc. , 11th road. Display circuit 20
6 is printing paper 7. It is used to indicate the occurrence of a jam, etc.

The DA signal and VDB signal (image signal) sent from MIMOUloo or the reader are converted into ternary values (
VD signal), is input to a laser driver 209, and is converted by a semiconductor laser 210 into a laser beam based on the VD signal.

The laser beam is applied to the photosensitive drum 2, which is rotated at a predetermined rate by a collimator 210 and a mirror 212.
Scanning is performed in a direction substantially parallel to the rotation axis of No. 14. The scanned laser beam undergoes light intensity correction by the f-theta lens 213, and is irradiated onto the photosensitive drum 214, forming a latent image of the ~DD signal.

Image formation in the printer is performed using a so-called electrostatic recording method.The required portion of the charge applied to the photosensitive drum 214 is completely removed using a laser beam [7], and all development processing is performed using a developer. This is done by transferring it to printing paper and applying a short layer. Since the electrostatic recording method is a well-known technique, detailed explanation will be omitted.

Now, the laser beam scanned by the polygon mirror 212 is incident on the optical fiber 215 before being irradiated onto the photosensitive drum 214, and when the photodetector 216 detects all of the incident light, it outputs an electric 1g signal (8D signal). . As can be seen from FIG. 5, the laser beam is emitted from the reader or MIMOUloo to the photosensitive drum 7 after the BDi@ signal is generated.
14 before outputting the VD signal, a latent image will be formed at an appropriate position on the photosensitive drum 214.

The output timing of this VD signal is specifically shown in the seventh section.
FIG.

In FIG. 7, an example of a reader is shown.
The same applies to MIMOIJ.

In Figure 2 (bl), from the generation of H5BD double by the BD signal generation, counting starts at the left margin color/re 68, and when the count up corresponds to the above time, the bit counter 69 is operated, and the memory 60.6
1 or starts reading the VD signal from the memories 62 and 63. The bit counter 69 stops operating after outputting the VD signal over the image forming area of the photosensitive drum 214, and prepares for the input of the H3BD signal based on the input of the next BD multiple number.

V E iU is an interval number indicating the period during which the bit counter 69 is operating. VE double signal, MI M OU
6i1 VC is used to control the operation of the VE counter 152 and the write counter 151.

In MIMOU, the VE generated by the control circuit 158
'The signal is also similar to the VE multiplied signal.

FIG. 13 shows a timing diagram of the image signal L:/)k in the image signal synthesis circuit 217 of FIG.

The image signal VDA is synchronized with the video clock VCLK.
, VDB are sent, so a VDO synthesized at twice the frequency of the video clock is output from the synthesis (b) path.

FIG. 8 shows an external view of the operating section provided on the reader connected to the system in this embodiment.

Further, FIG. 9 is a flowchart showing the timing signal of the reader. Standard operation section 252
includes a numeric keypad 254 for setting the number of sheets, and a set number display section 25.
5. It is equipped with a copy start key 253 and the like, and the method of use is the same as that of a commonly used copying machine.

The special operation section 250 is for the user to create any copy mode, and is fully equipped with a liquid crystal display section 256 that can display labels corresponding to the soft keys, copy mode, data, and various messages, and six soft keys 257. ,
When you want to select the content displayed on the liquid crystal display section 256, you can create all the contents such as the recopy mode by pressing the soft key 41411K corresponding to the display you want to select.

For example, a desired paper size can be selected from among the paper sizes sequentially displayed on the liquid crystal display using a soft key below the size display. The liquid crystal display unit 256 can also display information that cannot be displayed on the standard operation unit 252, such as information such as how many printers are being used when multiple printers are being used simultaneously for copying. I can do it.

The preset operation section 251 is capable of registering all copy modes (conditions) set by the standard operation section 252 and the special operation section 250. That is, the frequently used copy mode is registered in advance in the 2RAM 4Q, and the copy mode is read out from the memory with one key operation without using the entire special operation section 250, thereby making it easy to copy in the desired mode. It is something.

There are two ways to connect each device: one is to connect directly via a reader and a multi-input/multi-output device, and the other is to connect only the reader and printer.
(This is done with the application status of the reader and the multi-input multi-output device ifr. 111 As mentioned above, they are connected via a serial circuit to which individual numbers are assigned. is treated as a unique number for the reader.

The connection between the multi-input multi-output device d and the printer is as described in 1j11 (as well, since they are connected via each synchronous memory board, the multi-input multi-output device η is connected to all the values of the dip switch 186 on the synchronous memory Treated as a printer-specific number.

Kei, the retention memory unit has two connection wires coming out, one to the reader Tsukuda connector and the other to the
It is connected to the printer side connector.

When a reader is connected to a multi-input/multi-output printer, the reader can select either a single mode or a multi-mode print mode.

Single mode is the same mode as when only the reader and printer are fully connected, and is a mode in which printers with the same number as the printer's unique number assigned to the reader are connected. The status is a mode in which the reader receives a single file via the multi-input/multi-output device 4. On the other hand, the multi-mode is a mode in which one reader can connect to a plurality of unspecified printers via a multiple-input multiple-output device, and the printer is designated by the operation unit of the reader. In addition, there is also a mode in which the printer's fingers and toes are left to the multi-input multi-output device. Select appropriately and operate. Further, each status in the multi-mode 2 is sent to the reader by the multi-input multi-output device assembling all the information of each printer into the necessary format.

Below, the reader and printer 7 &: are directly connected one to one.

Since the control in this case is the same as the single mode control 1 using multi-input multi-output g+t*, oil purification in a system using a multi-input multi-output device will be explained.

There are three operation modes using the retention memory unit (1t to IU) 4 (Fig. 1). From then on, there will be a reproduction mode in which images are played back using the output from the reader memory unit 4, and an image signal from the reader. In the store mode, which only stores information in the retention memory unit 4, and in the monitor mode, which outputs the image information stored in the retention memory unit 4 and reproduces the image on the printer, these modes and readers can be specified at once. This retention memory unit 4 operates according to instructions from the reader.

An example of setting the general MU4 store mode in the special operation section 250 of the reader in FIG. 8 will be described below with reference to FIG. 16. In FIG. 8, 256 is a liquid crystal display, 257 is six soft keys (hereinafter referred to as SK or SKl).

That is, the reader can know what is connected to the system based on signals from the printer, and can allow all users to select an input mode according to the system configuration.

If the system Kl (M IJ 4 is connected, pressing the key 5K5 (<7) corresponding to 'ETC' allows you to enter the [t~IUJ mode]. Figure 16 ( 2) shows the entire state, and in that state, the key 5K2 corresponding to the display "RfVI IJ" is pressed.

After all the retention operations have been selected, you can press the start key after setting the number of copies in the same way as when operating a conventional copying machine. /In the same way as for the John operation, select the store operation by pressing the key SK3i corresponding to ``Store?'' which is displayed when the store operation is not selected. At this time, the display section passes through the state shown in FIG.
In the state of 6), the machine is waiting for key personnel. This corresponds to selecting which memory to store data in, SK1 to 5K3i, J, storing in memory A, memory B, and memories A and B, respectively. That is, when the key SKi corresponding to the stored memory is pressed, the memory is selected. After selecting the memory, the operator can store the original in the memory by pressing the start key, which is a preparatory operation for the overlay operation 2 and the monitor operation.

In the same way for monitor operation, if you press 4 on the key S corresponding to the display ``Monitor?'' when monitor operation is not selected in the MU input mode, monitor operation is selected and the display is After passing through the entire process of FIG. 16 (7), the memory section becomes as shown in FIG. Corresponds to outputs from memories A and B.

The operator presses the key 5K that corresponds to the memory that he wants to output.
After pressing i, you can set the number of copies to be made and then press the start key to perform all monitoring operations.

The output printer in the retention operation monitoring operation is the printer specified by the multi-indication or single instruction.

In addition, until the above-mentioned multi-mode instruction t, similar to the setting of the above-mentioned retention memory unit 4, the special operation section 25

In the implementation system, between each device d (reader and MIM
O(J, MIM(NJ and printer, lvi 1.
Information exchange between IVI O[, J and R, MU) is performed mainly by serial signal communication except for image information.

In serial communication, the reader takes initiative between the reader and MI to i0U, and the multiple input multiple output device takes the initiative between the multiple input multiple output device and the pre/receiving device.

MIMOU and f(, MU have the initiative in i(, MtJ in the interface connected to the reader side, and MIMOU in the interface connected to the printer side.

If you have the initiative, try to detect whether the other party can receive all serial signals or not, and check the other party's wire input bond and reception T3J.
If communication is possible, various commands are output in full serial code, and the receiving side receives the above command, checks for parity errors, etc., and if the command is valid, responds to that command. I will send back all the information. If the command requests some action on the receiving side, the corresponding action is performed.

In communication, the person with the initiative outputs all instruction codes (called a command), and the receiving side outputs information corresponding to the instruction code (
This is done in a one-to-one manner, in which the status (called status) is always sent back.

Table 1 shows status request commands for requesting printer information. When the multiple-input multiple-output device or printer receives the status request command, it returns a status signal corresponding to each status request command shown in Tables 2 to 11 to the reader.

The second line is the command error status that is returned if the received command is invalid, and if there is a parity error,
Bit 6 is set.

Table 1 shows all the statuses of the corresponding printers in single mode, and the overall status of available printers and printers in use in multimode. The print request, which is a paper feed ready signal, is
If all of the VCs are available for paper feeding, they are set. Paper in bit 5 (during general feeding, it is set if any of the printers in use is transporting paper. During misprint, waiting (fusing unit temperature rising), pause (shutoff 2 and 4), call error 61 (operator call &lj:?-Bismano call error hb>) bits 4.3 and 2.1 are sent when an error occurs in all the printers in use.

Table 3 Tables M4 and 5 show operator call errors, respectively.

Details of the serviceman call error are shown, and the bit corresponding to each error in each drive unit or process unit is set when the error occurs.

Table M6 shows the number of retransmission requests caused by jams or misprints.

Tables 7 and 8 show paper sizes of printers that support the single mode.

Table M9 in Table 8 is an application status that indicates to the reader whether or not the multiple unit and retention memory unit are connected, using bits 22 and 1. When the printer is directly connected to the reader, Bit 2, “Multiple unit present” has been reset.

Further, when a retention memory unit is connected, bit 1 "retention memory unit present" is set.

Tables 9 and 10 show the status of the printer as indicated by the printer information request status. Bit 6, Printer Ready, indicates that the compatible printer is capable of copying, and Bit 5, My Printer, indicates that the printer is the same as the reader that requested the information.
Indicates that it is a symbol printer. Bit 4.3.2.
1 indicates the respective cassette size.

Table 10 Table 11 shows the number of sheets fed in one copy. The final paper feed indicates that all the specified number of copies have been printed. Bit 5 (resend request) indicates that a jam or misprint has occurred in one of the printers in use, and a request is made to resend the image information. Indicates that a has occurred. The number of sheets is requested by a retransmission water absorption sheet number request.

Tables 11 and 12 show execution commands that prompt the printer for execution. When the execution command has been output, the MIMOU or printer and retention memory unit
The overall status shown in the table will be returned.

1 is a copy start command that requests the printer to start a copy operation, 2 is a printer stop command that requests a stop of a copy operation, and 3 and 4 are paper feed instruction commands that instruct the paper feed cassette in all directions when in single mode. 5 is a one-copy number instruction command, which instructs the total number of copies of one original. 6 is a multi-instruction command, which is set in the second byte in correspondence with the number of the printer to be used and each bit in the first byte (the first bit is for printer 1, the second bit is for printer 2). 7 is an instruction command indicating that the reader operates in single mode. 8 is a command for instructing the paper size, and in the case of multi-mode, it is output in a large number.

Table 12, 9, is the instruction to the rechin/yo/memory unit? This command is output from the reader when the reader is set to use the retention memory unit.

Table 13 specifically shows the reply/version memory unit instruction of 9 in Table 12.
5th step b 6 instructs which memory r is to be stored, and bit 4, which is set by the store mode instruction in the reader, is a bit that instructs the retention copy mode, and the reader is given the data/sho/mode. Set when selected.

Table 13 (Retention memory unit instruction command) lbit
8B 2nd bit The reader's microcomputer first performs the communication shown in Table 13, as shown in Figure 15, when it is not in the process of copying and does not have any key personnel. Let's do it. Further, the trip reader which also selects the fcHS BD signal according to the flowchart of FIG. Write down information on whether or not there is one. Also, learn how to connect the memory unit. Copy start check (St
After 5-2), when MIMOU is connected, the printer information request command is output 8 times, which corresponds to iMIMOU's printer connection enabled, and shows which printer is ready for printing and whether it is a single mode printer. Obtain all the information on what printer number it is, and what printer number it has paper of the same size in the upper/lower row (S15-4)
．． 5). Also, when MIMUU is not connected, it is a standalone/type, and the reader and printer are connected to MIMUU.
This is a case where the connection is made directly without going through the
The upper/lower cassette size is known from the output of the upper cassette status request command and the lower cassette status request command in the table (Sl5-6).

After obtaining the paper size information, etc. when MIMOtJ is connected or not connected, the overall status is obtained using the overall status request command shown in Table 1 (Sl 5
-7). However, at this stage, copy-7 is not yet in progress, so it is only determined whether or not there is a call error based on the overall status (Sl 5-8 ). If there is no call error, the process returns to requesting the application status in 515-1 and repeats these steps.

If there is a call error, detailed information on the serviceman call error is obtained by using the serviceman call error request command shown in Table 1 (Sl 5-9). Further, details of the operator call error are obtained by the operator call error request command shown in Table 1 (S15-10). Thereafter, the process returns to (S15-1) and the same process is repeated.

In this way, communication before the normal sequence is performed 1, and when the copy start key is pressed in the copy start check (S15-2), all operations shown in FIG. 1θ are executed.

FIG. 10 is a flowchart of the execution program of the microcomputer CPU during the image reading operation in the league.

The reader has various settings made by the operation unit, and when the copy start key is pressed, it first determines whether there is an RMU instruction, and if the instruction has been set by the operation (Step 5IOI), the RMU instruction command is issued. (SIO2).

Next, the paper size, printer number, and number of copies specified by the operation unit are output. The printer/parser outputs the designated number 't% in multi mode or its own number in single mode. Not output in RMU mode (slo-3, Sl 0-5, Sl
0-6). The printer number instruction is not specified when the RMU instruction is a store instruction, so it is not output.

Next, a copy start instruction command is output (SI
O-7).

If it is in the MU monitor mode, a green/tast knob is output and the operation ends (S10-20).

In other cases, wait until paper feed is enabled (Sl
0-9), when paper feeding is possible, output a paper feeding start instruction and start timer l at the same time (
S10-10, Sl0-11).

This timer l is in charge of the time from when the printer starts feeding paper until the paper comes to a position where an image can be formed. When the timer 1 counts up (510-12), scanning of the optical system is started (S10-13), and reading of the original is started (S10-14).

After reading the original, that is, outputting the image signal (S
l 0-15), import all copies (StO-16
). Then, if the RMU's restore/sho/mode is the store mode, the printer stops all output and completes the operation (Sl 0-17, Sl 0-20). In other modes, count down the total number of sheets SL 0-1
8'), check whether the final copy is completed or not (510)
-19), if not completed, repeat paper feed check possible. If the final copy has been completed, the printer stops all output and completes all operations (Sl 0-20 ).

FIG. 11 is a flowchart showing the operation of the micro/view when a copy start instruction is received from all readers of a multiple input multiple output device (MIMOU), and will be fully explained.

Step 5ll-1: If received, check whether the RMU instruction command has been received.
), if received, output instructions to the MU.51
1-2) If you have received the paper size and printer number, please send the printer number. Sl 1-3, Sl
1-4.511-5), and then outputs the number of copies (S1'1-6). Then, the copy start signal is output to the iRMU (S11-7), and the copy operation begins.

1 (If there is no MU instruction, first check the printer with the required paper size based on the printer number instruction and paper size instruction, and if there is no paper, send a paper out message and end the operation (S11- 9.511-10).

Upper and lower cassette instructions are output to printers with the required paper size, and then the total number of printers required is calculated using the printer number and the number of copies (511-11). A copy start signal is output to the necessary printer, and the copy operation begins (S11-12).

When a printer stop is received, the copying operation outputs each print/task and ends (S11-13.31
1-14).

All printers that output copy start can now feed paper.
Wait until the paper is ready to be fed and output to the reader that paper feeding is possible (S11-
15.511-16). When the paper feed start tf is received from the reader (Sl 1-17 ), the entire paper feed start is output to the required number of printers (Sl 1-18 ). and,
The image is output from the reader so that the image signal can be received (Sll-19'). Here, the error is checked, and if an error occurs (S11-20), all error processing is performed according to the condition (Sll-21),
Calculate the number of copies and send it to the reader (S11-22
). Then, it is checked whether all copies have been completed, and if all copies have been completed, a final copy completion message is sent to the reader, and the printer waits for the printer to stop. Also, if all copies have not been completed, restart from calculating the required number of printers (Sll-2
3,511-24).

FIG. 12 shows an execution program flowchart of the operation of the microcomputer of the printer during the image forming operation. If Copy Star) is received from MIMOU,
The printer starts all operations of each part according to the redundant sequence (step 512-2).

Since this system uses an electrostatic recording type printer using a drum as described above, pre-processing such as drum charging is required. Therefore, it waits until the preprocessing is completed and paper feeding becomes possible, and if it becomes possible, it starts feeding paper from the cassette instructed by MIMOU before copying starts (Sl 2-3).

312-4).

It waits until the fed paper reaches a position where image signals can be received (S12-5), and when it reaches the position, it outputs a signal 2MIMOU indicating that it is possible to receive image signals (S12-6).

When the image signal is input, a series of copy operations such as transfer to developing paper and ejecting the paper to the outside of the printer are performed (Sl 2-7
, Sl2-8).

Then, it detects whether an error has occurred during a series of copy operations and sends that information to iMIMOU (
Sl2-9, Sl2-10).

At that edge, when the printer stop signal is received, each part of the printer should be stopped and the series of copying operations should be completed.St 2-11
, Sl 2-13'), and when the copy start is received, the next copy is started (S12-12).

FIG. 14 shows a retention memory unit (RMU) 4.
This will be explained using a flowchart of an execution program of the copy operation of the microcomputer after receiving the copy start command. RMU is a multiple input multiple output device (MH
vlOU) 3 is connected to the reader-side connector and the printer-side connector, so instructions from the reader are input from the printer-side interface via the MIMOU-i7, and operation instructions to the printer are sent in the same way. Perform from the reader side interface. Therefore, usually MIM
If there is a status request from OU, 7' IJ

Next, regarding the copy operation, if )t, no MU instruction is received, nothing is done (step 514-1);
First, if there is an image storage instruction by a print/sho/or store instruction, the operation is similar to that of a printer (Sl 4-
2) Therefore, select the memory to store according to the RMU instruction. If it is a retention instruction, the above memo lJAg5
．． Use both Memo IJ 1186 (Sl 4-
3). Then, output all the paper that can be fed (Sl 4-4
). In response, the reader outputs a paper feed start signal,
Next, an image signal is output, so this is input and stored (Sl 4-5, Sl 4-6). Then, if the pre/tast button is received, the operation ends in the storage mode (S14-8), but in the retention output mode, the reader-side interface is all used next and the same operation as the reader is started.

First, re-output to the printer/par, paper size, and number of copies (4 MIMOU) received at the start of operation, and (Sl
4-9.31 4-1 0, Sl 4-1 1),
A copy star controller is output (Sl 4-12). Then, select the ERI output memory as the RMU instruction command/code. In the retention mode, both memory A85 and memory B86 are output (Sl-4-13).

514-14.514 Wait for all paper feeding possible inputs from MIMOU and output all paper feeding start instructions.514-14.514
-15), start timer 1.

This timer 1 is the same timer used in the explanation of the reader operation (Sl 4-16).

When this timer 1 expires, an image signal is output from each memo IJ (Sl4-IT, Sl4-18).

Picture 111! When the signal output is completed (S14-19), take in all copies (Sl 4-20), check whether the final paper feeding has been completed or not (514-21), and if it has not been completed, check whether paper feeding is possible. Will restart later. If the copy operation has been completed, a printer stop message is output and the copy operation is ended (Sl 4-22).
