Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an image processing system, and more specifically, an image processing system that processes images according to an image signal output from an image output unit such as an image reading device. Knob etc. are things that you can listen to.

Conventionally, an image processing device has been proposed that forms an image based on an image signal obtained by optically reading a document using an image sensor such as a COD, but this device has an image signal output section and an image forming section in one. This is a one-to-one correspondence; for example, if multiple image formations are desired, one image formation and the original reading are repeated.0Also, a composite of multiple image information is obtained. In some cases, there are problems in terms of configuration and cost, such as the need for a large capacity memory.The present invention has been made in view of the above points, and includes an output unit that outputs image information, and a memory that stores image information. In the image processing system, the storage section has a path for bypassing and outputting the input image information without storing the input image information, and the storage section is configured to store the input image information first. The present invention provides an image processing system that forms a composite image by the forming section by outputting image information in synchronization with the bypass output,
Further, the storage section operates according to instructions from the operation section of the output section. As a result, image synthesis can be performed at high speed with a relatively small memory capacity.

Hereinafter, the present invention will be explained in detail based on Examples.

A single language line is connected to printers 4 and 5 for recording images. In FIG. 1, the multiple input multiple output device includes a reader 1
Although two printers are r&ffl, it is possible to aim with more than 11 printers or less than 11 printers. Note that, as described later, the maximum number of connections is 4 readers and 8 printers in the original implementation.

In addition, in FIG. 1, the retention memory unit 2
14 are installed between the reader 1 and the multi-input multi-output device 30, but it is not limited to this position, and may be provided between the reader and the printer. For example, the multi-input multi-output device 3
and a printer 4 or 50 is also possible.

That is, as will be described later, between each unit, the vertical synchronization signal VSYNC for the image signal, the video enable signal vE indicating one line of the image, the image signals A and VB, the image synchronization signal VCLK, and the horizontal synchronization signal No. 8 Bl) are exchanged, and a common serial control number 46 for transmission of the image signal is exchanged. Therefore, the input/output section for exchanging these signals can be shared by each unit, and thereby, j-step combinations of units can be freely performed. In other words, each part of the 5 image processing system is made into a unit and connected in the same form using signal pins with the same meaning.It is easier to install and remove each unit than with RC, and because the form is the same, costs can be reduced. By connecting a plurality of multi-output devices 4, OJ functionality becomes possible and the system can be expanded.

Next, a detailed explanation of the inside of the reader 11, retention memory unit 2, multi-input multi-output device 3, and printers 4 and 5 will be given using ICJ figures 2 to 6.

FIGS. 2(a) and (+)) are configuration diagrams showing an example of the internal configuration of the reader 1. FIG. In this embodiment, in order to achieve high speed, high fidelity, and tail removal, a method is used in which the original image is read by two CCJJs and combined into one signal to generate one line of image signal. .

First, let's start with the explanation of Silk Figure 2 (a).

For Kyugaku V's 10.11, place it on the manuscript table (not shown) for 1 shift or tl.

#4 Change to RI*JA. This hypochondriacal signal is amplified by an amplifier circuit 14.15 and an analog/digital converter (A/
1) Converter) At 16.17, each pixel is converted into a multivalued digital 1B number indicating m degrees of image.

Furthermore, the digital signal is transmitted to the shading correction circuit 18.
In 19, the light emission unevenness of the light source, the unevenness of the luminous intensity of the optical system 1, C
After removing shading caused by CD unevenness, etc., the ternarization circuit 20.21 receives the 3-value digital image signal VDIA signal, VDl-
B signal and UVD 2, -A, (@ signal, VD2-B signal respectively).

Ternarization is performed by binarizing at two stages of binarization levels, but there is a method using a fixed binarization level given by the latch circuit 26, and a method using a fixed binarization level given by the dither ROM 24.25. The 0-dither method uses selectors 22 and 23 to select between two types of ternarization processing, the so-called dither method, which uses binarization levels that are periodically changed within the matrix size. This method is widely used in facsimile machines to reproduce halftones in a pseudo manner.

In addition, as mentioned later, the 3-value 1! ! Ii Image output is not necessarily required, and binary image signal output may be necessary. At this time, a suitable dark value for binarization of d% is supplied from the latch circuit 26 or the dither circuit 0M24.25.

In this implementation, it is possible to obtain an optimal double 4 image by selecting a method that gives a constant 21ii conversion level to text, etc., and a dithering method to documents that require gradation, such as photographs. It is also possible to make a selection such that the two stages of binarization levels given from the latch circuit 26 are the same value.

Dither) 40M24.25 sequentially reads out the dither butter/ stored in the adds 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 μs1 prime number in the main scanning direction. In addition, the 4-ki signal read by CCD12°CCLl13 is 1
In order to prevent the dither pattern from being disturbed at the joints when compositing into a line, the counter 291Chkj (
A latch circuit 30 is connected which provides preset data of 4 counts.

This latch circuit 30 and other latch circuits in FIG. 2 are connected to the CPU bus of CI'038, and

The CPLI38 can be set to
Control is performed for A adjustment and operation confirmation based on the c value ic.

The key display drive circuit 44 is a circuit for driving a display such as an operation τ (scanning the key matrix of the 8IS45 and LEi). This circuit is used to give control commands to the main memory unit and to receive information.

The oscillation 11 path 32 provides timing to the CCU drive circuit 31 that drives the CCDs 12 and 13 and other parts that suck the image. Oscillation number 13 is the counter 33
The count value is further counted by the decoder 34
is input to generate the timing for each building.

The decoder 34 generates the H8 value number of the same department for each l line in the sub-travel jf direction and inputs it to the selector 35. The selector 35 also receives a similar No. 19'' 1B BD signal (described later) sent from the printer when the printer is connected, and the CPU 38 follows the procedure shown in the flowchart in Figure J412. When a printer is directly connected to the reader, the BJJ signal is selected, and when the reader is exposed to a multi-input multi-output J device or a retention memory unit, the HS signal is automatically selected. The leftover signal is used as a synchronization signal in the direction of H8BD. (5BD) The number is also input to the color/return 38 and used as a count reset signal.

The counter 33 outputs the original clock of the input clock when inputting the image signal v lJ l 1M number and the VD2 signal to the mirror memories 60 to 63, and this original clock is used as the rate multiplier. 36, it becomes the memory common clock WCLK1N. The rate multiplier 36 divides the frequency of the input clock signal by the value of the 1b1" image signal (in this embodiment, the latch circuit 37) applied from the outside and outputs the divided clock signal. In this embodiment, it is used to transform the 1liIl image in the fixed and hill directions.

Next, FIG. 2(b) will be explained.

A memory address for generating the imported VJ)1 signal and Vυ2 signal is generated by a CLK signal (described later).

The memories are made up of a pair of memories 60, 61 and 62, 63, and when one pair is performing a read operation, the four pairs perform a read operation, so that the signal method j, At

The memory of the - set repeatedly performs the filling operation and the reading operation, and receives the signal from the write counter 53 during the filling operation, and the read signal when the reading is 1th+.
The signals from counters 54 and 55 are selectively applied from selectors 56 to 59 to create 11ib. The above-mentioned write operation and read operation repetition control is performed using the above-mentioned HS B

Similarly to the rate φ multiplier 36 and the latch circuit 37 mentioned above, a signal 1g is generated in the read clock signal CI. Further, a video enable (vg) signal, which will be explained in FIG. 7, is outputted from the control circuit 67 to a printer or the like.

In this way, by outputting the multi-level information obtained by reading the original through M number of signal lines, it is possible to output it using a video clock with a slower frequency than when outputting the synthesized 1# information. There is no need to use high-performance elements in the input/output circuit, and there is no need to use high-rise IM or number-responsive Akane Ikuura transmission lines for the transmission line, so the cost of the circuit can be reduced. IC with noise resistance etc.
can be raised.

'+tj of retention memory unit 2 according to FIG.
ll dExplain the 1st off-shore road map. The retention memory unit 2 is roughly divided into a memory section and an iH control section.
There is. The microcomputer 75 of the control unit is connected to the ROM 76, RAM 77.10, and the board 78. Timer circuit 79. It is connected to the serial communication circuit 80, and the operation of each part is the same as that of the league part, and the IO boat 78 is connected to each selector of the memory part. The serial circuit 80 can be connected in parallel to the league section and the printer section.

The memory section consists of memory A85 and memory 1386, each of which can store one A3 size [i! ii ('1) It is composed of a dynamic RAM etc. that can store information.The input line of the memory is a selector 97゜98;71. The image No. 1g generated as a value signal is written into the corresponding memory. Also, the image signal generated as a binary sign is written into one or both of the memo IJ A or B. Selected by the selector 97 The image signal sent to the shift register IA (82) is sent to the video clock VCLK.
It is written into the memory A (85) in synchronization with the address ID number d from the address generation circuit 83. Further, the image signal selected by the selector 98 is similarly written to the memory B (86) through the shift register IB (84). In this way, writing of two image signals is performed using a common video clock vCLK. Further, an address generation circuit 83 that specifies addresses of the memories is synchronized with the video clock VCKS and the video enable signal VES, and controls both the memories A and B at addresses 11+.

When the memory is loaded with J, the video clock VCKS4d input to the address generation circuit 83 is input to the Q by the selector 81.
The VCI communicated from the outside (reader) along with the % image fd, the internal occurrence port rJ 91 te occurrence L7'
CI CL K No. 5 also selects VC and LK. In addition, the input signal vES to the address generator circuit 83 is generated by the internal generator circuit 87 together with the signal vE communicated from the outside (for example, the league) together with the player M. Among the IV14, vE is selector 88]
selected. Incidentally, this address generation circuit 83 is also used when reproducing a song from memories A and B;

Incidentally, the input to the memo IJA, t3 and the start of reading are outputted by the CPU 75 via the I10 port 78.

The image information in memories A and B (85, 86) is output in accordance with the address signal from the address generation circuit 83, stored in two shift registers 213 (89, 90), and then sent to the internal generation circuit. The common video clocks ICI and K generated at 91 are divided and output as serial data.

At this time, the selector 81 selects internal fcLK as the video clock VCKS. Video enable Onoue circuit 87I'i is a circuit similar to the H8BD generating circuit in the league, and generates at the timing shown in FIG.

In this way, shift registers 2A and 2 are transferred from memories A and B.
Image No. 18, which is serially generated via line B, is selected by selectors 92 and 93 to which of the two image signal lines A and H it will be output. In the OR circuits 94 and 95, the output of the selector 92 or 93 and the through gate 99
1! II Rememory IJ f bypassed r1!
An OR with the aI image information is taken and output. Also, memory A.

Gate circuits 72 and 73 are used to perform the OR operation of both outputs of B and the clear image signal. 'In addition, the video clock is VCLK, which is communicated from the outside by the selector 96, and the internal generation circuit 91, depending on the operation mode.
The ICLK generated in is selected and output to the subsequent stage.

As explained above, the retention memory unit is designed to have memory for the number of signal lines for multi-level image information, which is composed of multiple signal lines, and to store it, and to allow data to be stored in each memory separately. By doing so, when you want to memorize a clear black and white binary image without the need for ternary representation such as a format, only one of the memories can be used.
f! Since the memory for one page of ternary image can be used for two
(+i 1li11+ It can also be used as a memory for two pages of images, and the range of utilization of the memory unit can be expanded.

In addition, it has multiple image information storage units that store two systems of image 1'# information that form the ternary tn information, and the output of each storage unit can be output to any of the 4M signal lines. As a result, for example, by outputting a signal to only one side of the ternary numbered line, the image reproduction capability is expanded, such as by making it possible to obtain an excitingly faint reproduced image when the signal lines from the original are overlapped.

In addition, in a system that communicates image information as multivalued information using a large number of signal lines, a common il! ii) By using the same M signal of the image information to communicate signals of the mantissa system, 11! It is also possible to reduce the cost by simplifying the input/output circuit for image information and reducing the number of signal lines.

Furthermore, the retention memory unit has a number of memory units corresponding to multiple image information (N pairs of lines), which can be easily written and outputted by a common address generation circuit. It is possible to control a plurality of memory units with a single path.

On the other hand, by making it possible for the retention memory unit to output the image signal from the reading device d and the image information already stored in the retention memory unit at the same time as when outputting it, 18! This not only speeds up image reproduction, but also improves image control functions.

In addition, the retention memory unit operates in the same manner as a printer when storing data, and operates in the same manner as a reading device when outputting an image signal.
The reading device can be operated without knowing the difference between the printer and the retention memory unit during storage, and the printer and multi-input multi-output device can be operated without knowing the difference between the reading device and the retention memory unit during image reproduction. You can operate these devices without knowing the difference, and the 17P of these devices! In addition to making it easier to create a system, the system can be easily configured (four times).

In this embodiment, the reader executes the 44th instruction to start copying, and the MLvIUU 100 is in the slave's relationship with the reader. For this reason, since it is not known when serial number 14 will be received from the reader or retention memory unit, MIMOU has a configuration in which one serial circuit is assigned to each image input section and the CPU 140 handles all serial numbers 18.

In FIG. 5, a selector 150 selects 16 of the images sent from a plurality of readers or retention memory units.
This is a switching circuit for selecting a reader control signal assigned to the CPU 140 from among the "1" image signals. The selected control signal is sent to the write counter 151 and the VE counter 152, and the 0 selector 182 generates an address signal for writing the image I= into the memories 171 to 178, a select signal for loading the memory, etc. ,

! ! It is synthesized into 3 signals (■1 signal) by the I-burner 217 and inputted to the laser driver 209, and the half-body laser 210 outputs V
It is converted into laser light based on the D signal. The laser light is
The light is focused by a collimator lens 211 and scanned in a direction substantially parallel to the rotation axis of the photosensitive drum 214, which is rotated by a polygon mirror 212 at a predetermined rate. The scanned laser beam is subjected to optical correction by the f-0 lens 213,
The Ak light is irradiated onto the drum 214 to form a latent image based on the VD signal.

Image formation in the printer uses a so-called static recording method, in which the required portion of the load applied to the photosensitive drum 214 is removed using a laser beam, and this is developed using a developer to produce an H1 print. This is done by sanding and reversing the layers. Since the static 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 laser fiber 215 before being irradiated onto the photosensitive drum 214, and when the laser beam 216 detects the incident, it sends out four warning signals (HD, ', ＠) is output. As can be seen from FIG. 6, if the VD signal is output after waiting for the time from when the Bi) signal is generated until the laser beam reaches the photosensitive drum 214 from the reader, retention memory unit, or MIMOUl 00, the photosensitive drum An image a is formed at an appropriate position on 214.

Figure 49 shows the main example Vζ connected to this system.
The operation unit provided on the reader is shown. The operation sections include a mark f4 operation section 252, a preset operation section 251% liquid crystal length display section 25
6 and soft key 257 are Y Nene, 19 Tamotsu 1 and 250
The operation section 252 is equipped with a numeric keypad 254 for setting the number of sheets, a revised number display section 255, and a copy start 1,000-253). It is.

The special operation section 250 is for the user to create an arbitrary copy mode, and includes 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 change the copy mode etc. by pressing the soft key below the display you want to select (C).

For example, among the hook sizes of the number of bags that can be used for the Asahi Tsukiyoshi, the required size can be selected by using the soft key below the size display. In addition, the liquid crystal display section 256 also displays information that cannot be displayed in the 4-vote section 252, such as how many printers are being used during copying when four printers are being used simultaneously. 1n report can also be explained.

The preset operation section 251 is configured to set a copy mode (mV) using the standard edge [゛[ section 252 or the special operation section 250].
You can now record. That is, by registering frequently used copy modes in the AM 40 in advance and reading the copy mode from the memory with a single key operation without using the special operating section 250, copying in the desired mode can be easily performed. 0 The connection methods for each device are as follows: connecting the reader to a printer via a retention memory unit and a multi-input/multi-output device; connecting a league tension memory unit to a printer; There are four ways to connect an input multi-output device and a printer, and to connect only a reader and a printer, but for this reason, the input and output sections of each device in the system have the same form, so any connection can be made. Also,
The determination of this contact α state is performed using the application status described later. ! '! Since the multi-input multi-output device is connected via the r, the multi-input multi-output device is treated as the l1 number of the multi-input multi-output device and the printer or retention memory unit via the league or retention memory unit. As mentioned above, the connection is made through each synchronous memo IJnoti&, so multiple input and multiple output JAfi! 2 treats the value of the DIP switch 186 on the synchronous memory as the number of the printer.

The league is connected to a multiple input multiple output device directly or indirectly through a retention memory unit.

I also connected it to a printer. You can select either single mode or multi-mode print mode in 1 go, league mode. In this mode, a multi-input multi-output device connects a printer with the same number as the unique number assigned to the reader.In this case, each status is the status of a single printer received by the reader via the multi-input multi-output device. It is one.

On the other hand, the multi-mode is a mode in which one reader can be connected to an unspecified number of printers via a multiple-input multiple-output device, and the deviation/misalignment is specified by the operation section of the reader. In addition, there is also a mode in which the printer is specified as a multi-input multi-output device d fc reed in the multi-mode, but in this case, the multi-input multi-output device rt is set to Appropriately select the required number of printers and operate them. Also, in multi mode, 0
For each status, a multi-input multi-output device assembles the information of each printer into a required format and sends it to the league.

Hereinafter, the 11llJ1, 14I which connects league printers 1 to 1 is the same as the 1lilJ control in the shift mode using a high output embryo 1ling, so
A description of communication with 7 stems via a multiple-input multiple-output device and a retention memory 22) will be presented. 1.Differences between single mode and multi mode will be explained in each case.

By the way, there are four operating modes using the retention memory unit shown in FIG. That is, for the first sheet, the image signals from the reader are stored in all the retention memory units, and at the same time, the printer generates 14 images, and for the second and subsequent sheets, images are reproduced using the output from the retention memory unit, and a number of copies are made. There is a resolution/resonance mode in which image information stored in advance is combined with the output signal from the league, and an overlay mode in which the output signal from the league is reproduced on a printer.
Transfer the image signal of the reader to the retention memory unit #i
There is a store mode in which you simply print images, and a monitor mode in which the image information stored in the retention memory unit is output and reproduced on the printer.These modes can be specified in the league, and any In the Retention Memory Unit (hereinafter referred to as MU) mode, an example of setting the RM and U (Retention Memory Unit) modes in the special operation section 250 of the league will be explained below with reference to FIG. 10th
In the figure, a 256Vi liquid crystal display section and 257 are six soft keys (hereinafter referred to as 5Kt- or 5KI-8K6). The liquid crystal display section 256 Vc displays a display corresponding to SKI to SK6.

When electrophoresis is applied, the liquid crystal display section 256 displays a portion KETC (*) corresponding to the key SK6, as shown in FIG. 10 (1). Each time the key SK6 is pressed, the contents of the display section 256 corresponding to the keys 5KI-8K5 cycle and change, and the input mode is changed according to the contents of the system r4.

Choices are now available.

In other words, the reader relies on signals from the printer.

The system allows the user to understand what is connected to the system and select an input mode according to the system configuration.

If an RMU is connected to the system.

By pressing the key SK6 corresponding to “ETC”h? , the selectable status of the RMU input mode is displayed. Fig. 10 (2) K shows the state. In this state, the key SK2 corresponding to the 5 display "RMU?-"
Pressing K selects fiRMU mode. (RM
If you do not select the U mode, press the key SK6 corresponding to the 1 display "ETC-" and the display on the liquid crystal display section 256 will change and you will move to the next input mode.
If U is not connected, the display shown in FIG. 10 (2) will not be displayed.

When the display section 256 is in the state shown in FIG. 10 (2), the key SK is pressed.
If you press 2, RMU mode is selected and 1 display section 25
6 changes to a display as shown in FIG. 10 (3). Here, the keys SKI to SK4 each have retention mode (high-speed retention using memory), overlay mode (superposition of memorized originals), store mode (storage of originals in memory), and monitor mode (sweeping out from memory).
corresponds. Note 1: Key S corresponding to the display "BACK'"
When K6 is pressed, the display section 256 will appear in Figure 1O (2
), the mode returns to the input mode in which RMU mode selection is performed again.

In the display state of FIG. 10 (3), a desired one is selected from among the four modes of the RMU. For example, if the key SKI corresponding to the 1 display "Retention?" is pressed, the retention mode is selected. is selected and key SK
The display section corresponding to I changes from "Retention 7" to "Retention 1" as shown in FIG. 10 (4). Here, the "?" mark indicates that the corresponding mode is not selected, and when the corresponding key SK is pressed, the "?" mark indicates that the mode has been selected. On the other hand, the "1" mark indicates that the mode has already been selected.

After selecting the retention mode, press the start key 253 after setting the number of copies using the numeric keypad 254, similar to the operation of a conventional copying machine. , a predetermined number of images can be formed by reading the document once and reading the number of sheets from the memory. At this time, the selector in the retention memory is operated so that the two systems of ternary information VDA and VDB read by the reader are written into the corresponding memories A and H, respectively.

Next, in the %RMU input mode, press the key SK2 corresponding to 1 display "Overlay? 1" (if the lay mode is not selected (for example, when the 10th section (3) is displayed) teeth.

Overlay mode can be selected. When the over-lens mode is selected, the display section 256 will be displayed as shown in FIG. 10 (3).
The display changes from (5) to (5), and then the display state shown in FIG.

In this ζ, it is selected which image stored in the two memories A and B of the retention memory unit is to be superimposed on the * & phase ub+ image, and keys SKI to SK4 are used to select the memory This corresponds to the selection of overlapping with A, memory B, memory A, B, and memo IJ A+13 (details will be described later). The operator is
After selecting the memory you want to superimpose using keys SKI to SK4, use the numeric keypad 254 to set copy & number, and press the start key 253 to save the document image currently being read and the retention memory unit. The overlay operation with the currently displayed image is performed a desired number of times.

As in the case of retention mode and overlay mode, when store mode is not selected in RMU input mode, key SK3 corresponding to "Store?1" is displayed.
By pressing .

Store mode is selected. At this time, the display unit 256 goes through the state shown in FIG. 10 (7) and then enters the state shown in FIG. This is the selection of which memory in the retention memory unit the image information read by the reader is stored in, and the keys SK1 to SK3 are used in memory A and memory A, respectively.
Memory B.

This corresponds to storing memories A and BK. That is,
Here, the desired memory is selected by pressing the SK corresponding to the memory to be stored. Note that when either memory A or memory B is selected, the hv-da outputs both images as multiples of 2. On the other hand, if memory AB is selected, it is output as a multiple of 3. % after memory selection
By pressing the start key 253.

The original is stored in memory. This is good.

This is a preparatory operation for overlay mode and monitor mode.

In the case of monitor mode, in the same way, 1 display 1 is displayed when monitor mode is not selected in RMU input mode.
monitor? When the key SK4 corresponding to " is pressed, the monitor mode is selected and the display section 256 shows %Fig. 10 +91 f
r, then (11).Then, the user waits for an input as to which memory in the retention memory unit should output the stored image information.The keys SKI to SK3 are used for memory A, memory B, and memory B, respectively. This corresponds to the output from memories A and B. In this way, after pressing the key SK corresponding to the memory to which the operator wants to output, the operator sets the required number of copies using the numeric keypad 254 and presses the start key 253.

Monitor mode is executed.

In this way, when a retention memory unit is provided, the memory can be used to selectively execute the 4iB operations of the retention mode, 9 synthesis mode, store mode, and monitor mode from the programmer section. can be done.

In addition, by making it possible to display whether or not a retention memory unit is connected on the operation panel of the reading device, the connected units of the entire system can be visually recognized at the reading device. Operability is improved by allowing the operator to easily deal with the situation, and by specifying the retention memory unit and instructing each operation request.

On the other hand, the instructions for the multi-mode mentioned above are similar to the settings for the retention memory unit mentioned above, and are they special operations? N! 1ls25
The number of the printer connected to 0 is displayed, and this printer number is selected using a soft key, but since this is detailed in Japanese Patent Application No. 58-63851, we will not explain the details here. Further explanation will be omitted.

- Table 14 describes the operations of the reader, multi-output device, printer, and communication between the devices during image forming operation (hereinafter referred to as copy operation) by one system.

In the table, ■ indicates the operation in the reader and the operation of the reader, and ■ indicates the communication between the reader and the retention memory unit.
Operation of the 0 branch retention memory unit, 0 is communication between the retention memory unit and multiple input multiple output device, 0 is operation of multiple input multiple output device, (E) is communication between multiple input multiple output devices, Q is printer shows the operation. In the implementation system, between each device (reader and retention memory unit, retention memory unit and multi-input multi-output device,
Exchange of information between the multiple input/multi-output device and the printer/receiver is mainly performed by serial signal communication except for one-picture information.

In serial communication, a reader is used between a reader and a retention memory unit, a retention memory unit is used between a retention memory unit and a multi-input multi-output device, and a multi-input multi-output device is used between a multi-input multi-output device and a printer. Take initiative.

The person with the initiative detects whether the other party is able to receive serial signals (by the other party's power-on signal or receivable signal shout) 1) If communication is possible, output various commands in serial code, The receiving side receives the above command,
Parity errors and the like are checked, and if the command is valid, information corresponding to the command is sent back (however, the tension memory unit may use a different communication method, which will be described later). Then, the command is sent to the receiving side.
If a specific action is requested, perform the corresponding action.

In communication, the person with the initiative outputs an instruction code (called a command), and the receiving side outputs information corresponding to that instruction code (
This is done using a one-to-one method that always sends and returns 2 called status.

FIG. 11 shows the overall basic flow of KRMU communication.

Communication between the reader side unit and the printer side 22 bits is carried out using an 8-bit command and status format. That is, the command is sent from the printer side unit to the printer side unit (including multiple input/multiple output devices).

In response, the status is sent back from the printer side unit to the reader side unit. At this time, one status is always returned in response to one command, and the status is never sent before the command.

First, the RMU inputs a command from the reader side (810
1). It is determined whether this command is RMU instruction data in Table 13, which will be described later (8102). If the input command is RMU instruction data, the RMU operation is started (8103), and the overall status shown in Table 3, which will be described later, is returned to the reader side (S104). (On this occasion.

No commands are sent to the printer side (MIMOU).

) If the input command is not %RMU instruction data, the RMU determines whether it is necessary to send the command to the printer side (8105), and if it is not necessary, sends the overall status to the reader side. Return (S1
04). On the other hand, if it is necessary to send the input command to the printer side, the same command is sent to the printer side (S106).

When the printer side unit receives a command from the RMU, it returns a status according to the command within a certain period of time. RMU is the printer side) When receiving the status (
S107. ), it is determined whether the returned status is the application status shown in Table 9 below (8108).

If the status is not an application status, the status returned from the printer side is sent as is to the reader side (S110). On the other hand, if the status from the printer side is an application status, information as to whether the RMU is connected to the system must be added to the application status. Therefore, if the status received from the printer side is an application status, R
After processing the status to the MU connection state (S109
), the status is returned to the printer side (SIIO).

In this way, in response to a command from the reader side, the RMU transfers the command to the printer side or returns the overall status to the reader side. When a status is returned from the printer side, the status is returned to the reader side unit after processing the IT state or status, which is repeated as one cycle.

In this way, information from each unit is encoded and communicated, and the memory unit receives only necessary information while other information is passed through. !
It is possible to increase the speed of the transmission time, and it is also possible to simplify the communication protocol because only the unit on the reading device side monitors one communication.

Below, we will provide a detailed explanation of the operations and communications of each part shown in Section 14 2.0 Table 1 shows the status request command that requests printer information.0 This is sent to the printer side unit via the retention memory unit. . 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 table is
The command error status is returned when the received command is invalid.
is set to 0. The third table is a 0 paper feed ready signal in which each reader indicates the status of the corresponding printer in single mode, and the available printers and the overall status of the printer in use in multimode. A print request is set when all printers in use are capable of printing navy blue paper. Bit 5 during paper transport is set if any of the printers in use is transporting paper. 0 Misprint, Waiting (fusing unit heating up), Pause (shutoff and power saving), Call Error foot (operator: y -#
i;l'rui"su°-bisman call error asi)
Each bit 4.3.2.1 is set when an error occurs in all printers in use.

Tables 4 and 5 show details of operator call errors and serviceman call errors, respectively, and the bits corresponding to each error in each drive unit and process unit are set when the error occurs.

Table 6 shows the number of retransmission requests caused by jams and misprints.

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

Table 9 shows the application status, which indicates to the reader whether or not the duplex unit and retention memory unit are connected, using bits 2 and 1. When the printer is directly connected to the reader, the pit 2 The bit 1 of the retention memory unit is set to 0 when the retention memory unit is connected.

Table 10 shows 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 has the same number as the printer requesting information. Bit 4.3.2.1
indicates the respective cassette size.

Table 11 shows the number of sheets fed in one copy. The final paper feed indicates that printing of all the specified number of copies has been completed. Bit 5, ``Retransmission request present'', indicates that a jam or a misprint has occurred in one of the printers in use, and a request for retransmission of image information has occurred. The number of sheets is requested by the retransmission request number of sheets request.

Table 12 shows execution commands that prompt the printer to execute. When the execution command is output, the MIMOU or printer and retention memory unit return the overall status shown in Table 3.

1Fi 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 direction in single mode. 5 is a number-of-copies instruction command, which indicates the number of copies of one original.

6 is a multi-instruction command, which sets the number of the printer to be used in the second byte corresponding to each bit of one byte (printer 1 is set to the 1st bit, printer 2 is set to the 2nd bit). 7 is an instruction command indicating that the reader operates in single mode. 8 is a command instructing the paper size, which is output to the reader in the multi-mode.

9 is a command indicating an instruction to the retention memory unit, which is output from the reader when the reader is set to use the retention memory unit.

Table 13 specifically shows the instruction contents of the second byte of the retention memory unit instruction command 9 in Table 12. Bits 5 and 6 of the second byte are for memories A and B in the retention memory unit. bit 4 instructs to pass the image signal through without going through the memory. Bit 3 and bit 2 instruct which memory A or B the image is to be output from. Therefore, in a normal copy operation, bit 4 is set to pass through, and in retention mode, bit 4 is set to pass through.
The pass-through instruction bit of , and the memory storage instruction bits of bits 5 and 6 are set. Further, in the store mode, the storage instruction bits of bit 6 and bit 5 are respectively set according to instructions from the operation section. Furthermore, in the monitor mode, bits 2 and 3 are set respectively according to instructions from the operating section. In the overlay mode, bit 4, the clear pass instruction bit, and bit 2 or bit 3, the image output bit, are set.

Serial communication using each of the above-mentioned commands will be further explained below using the flowchart of FIG. 12.

First, when the copy sequence is not being executed and there is no key personnel, the first communication as shown in FIG.
4. Perform before the communication shown in Table 4. The H8BD signal is also selected according to the flowchart of FIG. 12 described above.

First, the reader outputs an application status request command and inputs the application status (S16
-1) to obtain information on whether MIMOU is connected. Also, learn how to connect the retention memory unit. After copy start check (816-2),
When MIMOU is connected, the printer information request command is sent as 8, which corresponds to the number of printers that can be connected to MIMOU.
Output times to get information about what number of grits are ready to print, what number of reeds the single mode printer has, and what size of paper the printer has on the top/bottom. 816-4.5). Also, MIMOU
If it is not connected, it is a stand-alone type, and the reader and printer are directly connected without going through MIMOU. Therefore, the upper cassette status request command and lower cassette status request command in Table 1. Know the cassette size of the upper/lower output cassette (816
-6).

After obtaining the paper size information, etc. when the MIMOU is connected or not connected, use the overall status request command in Table 1 to obtain the overall status (816 7) o However, at this stage Since the b-sequence is not yet being executed, it is only determined whether or not the overall status is 2- (S16-).
8').

If there is no call error, the process returns to requesting the application status in step 516-1, and repeats these steps.

If there is a call error, use the serviceman call error report request command shown in Table 1 to obtain detailed information on the serviceman call error (S16-9). Furthermore, the details of the operator call error are obtained using the operator call error request command shown in Table 1 (816-10). Thereafter, the process returns to (816-1) and repeats the same steps.

In this way, the communication before the normal sequence is performed, and when the copy start check (816-2) is performed and the copy start key is pressed, the operations shown in Table 14 are executed.

Next, the communication operation during the copy sequence will be explained with reference to Table 14. In the copy operation in the RMU operation mode, as shown in Table 14, first, the reader issues an RMU operation instruction. , RMU performs retention operation, overlay operation, store operation, according to the instructions.
Start one of the monitor operations.

The copy operation in multi-mode when the RMU is connected to the MIMOU will be described below.

First, when the operator inputs image forming conditions such as paper size and number of copies (one copy in store mode) from the operation panel in the reader and presses the copy key, the reader selects the paper size. , the printer number and number of sheets are sent to the printer side (RMU). Paper size is RMU
It is transferred to MIMOU after being captured in . The printer number is directly transferred to tMIMOU.

After receiving the paper size, printer number, and number of sheets, MIMOU checks each printer connected to MIMOU (in printer specification mode, only the specified printer) is a printer that can copy and has the specified paper size. Calculate the number of printers. Furthermore, the number of copies per sheet is checked and the number of printers required is calculated. Once the required number of printers has been calculated, a cassette stage with the required paper size is specified for each corresponding printer by communicating with the printer.

After instructing the paper size, printer number, and number of copies, the reader sends a copy start command to the printer side. When the RMU receives the copy start command, it prepares to proceed to a copy operation if it is not a store operation, and also transfers the copy start command to the MIMOU. MIMOU
When receiving the copy start command, the printer sends the copy start command to each printer for which the paper size/capturing instruction has been completed. When each printer receives a copy start,
When each part of the printer starts operating and it becomes possible to receive an image signal according to the conditions of each printer, each sends a signal indicating that paper feeding is possible to the MIMOU.

The MIMOU waits until paper feed enable signals are transmitted from all the printers required for printing, and after all the printers become capable of paper feed, it transmits a signal indicating the paper feed enable signal to the reader through the RMUe.

The above is a case other than a store operation, but in the case of a store operation, after receiving a copy start signal from the reader, the RMU directly sends the signal to the reader without transmitting the signal to the printer side (MIMOU). Send a signal indicating a paper feed enable signal 0 In cases other than store operation, the reader transmits a paper feed start signal to the printer side (RMU) after receiving the paper feed enable signal.

The paper feed start signal is sent from the reader to the MIM via the RMU.
The oMIMOU sent to the OU transfers the paper feed start signal sent from the RMU to the necessary printer. 0 In cases other than the second or subsequent sheets of monitor operation and retention operation, the reader will send the image after the paper feed start signal. is read and the image signal is sent to the printer side (RMU').

The RMU controls image signals through each RMU operation. That is, in the case of the first copy in the retention operation, the image signal is stored in the memory of the retention memory unit and simultaneously transmitted to the printer side (MIMOU).On the other hand, in the case of the second and subsequent copies in the retention operation, , in the case of monitor operation, image 1 from the reader side
The RMU sends the data from the memory as an image signal to the printer side (MIMOU). Also,
In the case of overlay operation, the image signal from the reader and the signal from the memory are combined in synchronization and then transmitted to the printer side (MIMOU) as an image signal. However, in the case of a store operation, the image signal is only stored in the memory and is not sent to the printer side (MIMOU).

In cases other than store operations, when the copy is completed, MIMOU sends the number of copies made in one operation to the reader via RM U, and also returns the number of copies initially instructed by the reader. Check whether it has been reached and
Once all copies have been completed, the league will be notified via communication that the copying has been completed. However, if all the copies have not been completed, the copy start signal is sent again to the required number of printers and waits until all the printers are ready to receive images.

When the reader receives the number of sheets from MIMOU via communication via the RMU, it decreases the number of sheets displayed. Then, when a paper feed enable signal is received from MIMOU, reading of the same document is started again. This operation continues until an instruction signal for finishing the final copy is received.

However, in the case of a store operation, the number of copies is set to 1 as described above, the image signal is not sent from the RMU to the MIMOU, and the final copy completion signal is sent directly from the RMU to the reader without going through the MIMOU. .

When the reader receives the final copy end, it communicatively sends a signal indicating printer stop to the MIMOU via the RMU. Δ(When the IMOU receives the printer stop signal, it sends the printer stop signal to all printers in use. When the printer receives the printer stop signal,
Stop the operation of each operating part of the printer.

FIG. 14 shows the flow of multi-mode reader operation using M I M OU% RMU.

First, when the copy key is pressed by the operator, the reader issues an RMU operation instruction (SIO-1), paper size instruction (810-2), and printer number instruction (S1) to the RMU.
o-a), specify the number of copies (810-4),
Perform the initial settings necessary for the copy operation. Also, for the RMU, the binarization circuit is set to output binary values when writing to only one side of memory A or memory B (S10
-25.1O-26) On the other hand, when writing to both memories A and H, three values are output (810-27).

Next, the reader issues a copy start instruction to the printer side (RMU) (SIO-5). Furthermore, the leader
Determine whether it is in RMU monitor mode (SI
O-6). If the printer is not in the RMU monitor mode and the printer is in a state where paper feeding is possible (S1o-7), the printer side (RMU) should be instructed to start feeding paper (810-s).
, starts timer l (810-9) and waits for a certain period of time until timer 1 times out (810-10).
, performs an optical system scan start (810-11),
The document reading is started (810-12). Furthermore, after waiting until the reading is completed (810-13), the number of copies sent from the 1st reader side is input (S1
0-14). On the other hand, in the RMU monitor mode, input the paper feed enable signal (5IO-20) L.

After that, send the paper feed start signal 5IO-21),
Furthermore, timer 2 is started (sio-22), and after the timer has expired after a certain period of time (SIO-23), the number of copies sent from the printer side is input (810-
14).

Next, the reader determines whether to print in RMU store mode (5IO-1s), and if it is in RMU store mode, sends a printer stop signal to the printer side,
Terminate the copy operation (81θ-24) If it is not the oRMU store mode, count down the set number of copies based on the number of copies sent from the printer side (SIO-16). The reader then checks the 7 lags to see if the final copy has finished (SI
O-17) When the final copy is completed, a printer stop signal is sent to the printer to end the copy operation (810-24).

If the final copy is not completed, the copy operation is repeated until it is completed. First, RMU retention mode (slo-18) and RMU monitor mode (8
After the determination in 10-19) is made, the process returns to the same flow as the first monitor mode copy (810-20)% RM
Wait for U to flush memory. However, in other cases,
Return to the flow of copying the first sheet in a mode other than RMU monitor mode (
SIO-7), performs optical system scan.

As described above, when storing the output of the reading device in the retention memory unit, if only memory A or B is specified, the reading device automatically converts it into binary output, thereby preventing image information from being lost. It has become possible to configure a system that is easy to operate without requiring the operator to be aware of such things. Also, in retention mode or when the operator selects both memories A and B, the reader
It automatically outputs the value.

In addition, by reading and managing the output of the memory unit with a device, the operator can know the number of reproduced images, and the processing load on the memory unit, etc. can be reduced. Table 14 shows the operation of the MIMOU microcomputer during the image forming operation shown in Table 14. However, in the case of multi mode, it starts from 5ll-1, and in the case of single mode, it starts from 811-7. In case of multi mode, when the paper size and printer number instructions are received from the series via communication, each printer's paper Check size (Sll-1, 8112)
n In this case, in the printer instruction mode, only the specified printer is checked, and in the non-specified mode, all printers are checked.

In this system, MIMOU and the printer constantly exchange various information through communication, and this information is
Since it is stored in Random Access Memory (M), you can determine whether the paper size is available by checking that information. Check the paper sizes of all available printers, and make sure none of the printers have the specified paper. If so, it sends a message indicating that there is no paper to the reader (Sll 3, 811 4).

If a printer with the required paper size is connected, the number of copies is received (SIX-5).

The number of received copies is compared with the number of printers having the required paper size, and the number of required printers is calculated (8116).

When the reader receives a copy start command, it instructs each printer corresponding to the calculated number of printers to start a copy operation (Sll-7, 511-8). However, in single mode, a specific printer is instructed to start copying.

When each printer starts a copy operation and becomes capable of receiving image signals, each printer receives a notification to that effect, and when all printers that have instructed the copy operation become able to receive image signals, they inform the reader that they are ready to receive image signals. Send (SIX 9+ si
i10).

The received image signals are simultaneously sent to each printer without going through the microcomputer. A copy operation is performed in each printer, and MIMOU detects whether a copy error occurs due to an error in each printer, calculates the number of copies, and sends it to the reader (811 12 + 811 13
．． 811 14).

However, in single mode, the copy operation is not changed until printer stop is received (S1116).
Compare the number of copies received from the reader at the start of copying, and if the instructed number is not reached, calculate the required number again and restart the copying process (811-17.S11.-
18).

When the instructed copying is completed, final copy completion information is sent to the reader, and when printer stop is received,
Send printer stop to all printers and end the series of operations (Sll-19, 811-20, 5ll-21
).

FIG. 16 shows the operation of the microcomputer of the printer during the image forming operation shown in Table 14. When copy start is received from MIMOU, the printer starts operating each part according to the predetermined sequence (81
2-2).

Since this system uses an electrostatic recording printer using a drum as described above, preprocessing 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. S 12-4').

It waits until the fed paper reaches a position where image signals can be received (812-5), and when it reaches the position, it outputs a signal indicating that it is possible to receive image signals to MIMOU (S12-6).

When the image ID No. d is input, a series of copying operations such as development, transfer to paper, and ejecting the paper to the outside of the printer are performed (812-7
, 812-8).

System detects whether an error has occurred in a series of copy operations and sends the information to MIMOU (S1
2-9, 812-10).

After that, when a printer stop message is received, each part of the printer is stopped and the series of copying operations is completed.
512-13), when the copy start is received, start the next copy (812 12)n Fig. 14(a)-(

FIG. 17(b) shows the flow of operations in the retention mode. After receiving the retention operation designation by the operator's key operation on the operation panel, the RM U specifies the number of sheets (811
6), and starts the retention operation when the start key (8117) is pressed manually.After the start key is input, the RMU starts the retention operation.
It is determined whether the OU is included in the system (8118), and thereby the horizontal direction Mr+@H

For the formation of the second and subsequent sheets, four high-speed retention operations are performed by sweeping out the data from the memory stored in the memory for forming the first one-image image without performing the original deposition βr.

First, it is determined whether it is the first copy (8
121), if it is the first copy, turn on the pass-through gate 99 to pass through the read image r image t-, and operate the selectors 97 and 98 to input the input signals VDA and V
After setting the DB to be stored in memory A (MA) and memory B (MB), respectively (S122), -Hyakuke Sototsuku 8123) and memory storage (S124) are performed simultaneously.

On the other hand, in the case of copying the second or subsequent sheets, selector 92.
93i, set the output of memory A (MA) to output VDA, the output of memory B (MB) to output VDB (8125), and output the data swept from memories A and B. 8126), performs retention. The image (ψ output) from the memory is repeated until the end number of images is reached (S127).

As described above, when operating in retention mode, the reading device performs only one reading operation regardless of the set number of sheets, making it possible to configure a system that is easy for the operator to operate. Became.

FIGS. 14(c) and 14(d) show the flow of operations in the overlay mode. The RMU starts the overlay operation when the user selects the memory (8128), specifies the number of sheets (8129), and inputs the start key (8130) after receiving the designation of the overlay operation using the user's operation keys. Memory selection (8128) specifies whether the number of strokes from document reading and the image read from which memory are to be adjusted by one degree, memory A, memo IJB.

Memory AB (original and image, 3 fi negative'1'i?

R1vlU, which is the selection of +B (a total of 3 pages of overlay of the original image f and 1 image of 2 pages stored as binary information in memories A and H, respectively), is for the retention operation. Similarly, after the start key is pressed, A4
It is determined whether the I M OU is incorporated into the system (8131), and the horizontal synchronization signal is selected accordingly. That is, the system has MIMOU
At t4, when the MIMOU is incorporated and twisted, the BD sent from the reader side is used as the horizontal synchronization signal (S132), and if the MIMOU is not installed in the system, H8 is used as the horizontal synchronization signal (Sl33). This operation is similar to that in retention mode.

Furthermore, the RMU sets each selector according to the memory selection. First, in order to directly send the Haratou Picture Story information that will be taken to @ to the printer 11I-1 without going through the memory, turn on the through gate 99 (5134), and then select the memory (8128). Based on the answer, the selectors 92 and 930 are set to output the desired video from the memory.

Is memory A selected (memory AB?

That is, if A+B is selected, 5136S13
All the operations 9 and 5142 are performed, and the original and both parts and the images in the two memories are combined to form a three-page overlay (8142).

After the valley gate configuration is completed, the RMU performs Ifj,

An overlay operation is performed by synchronizing and simultaneously outputting the sweep data from the other data (S143).

The 1 width 1r image output is manipulated back until the final number of sheets is reached (
8144).

FIG. 17(e) shows the flow of operations in store mode. RMUVi, after receiving the store operation specification by the user's operation key, selects the memory (8145)
, the store operation is started by pressing the start key (8146). Memory selection (8145) specifies which memory to store the original in: memory A, memo IJB,
This is the selection of memory AB.

After pressing the start key, the RMU selects the H8 signal generated in the ItMU as the horizontal +V+ signal of the ll1Il image (S147), and then selects in which memory the data is to be stored.

First, it is determined whether memory A is selected (including memory ABJJ selection) or not (8148), and if it is selected, the selector 97 is operated and the VDA is set to memory A (8148). (S149).

Similarly, whether memory B is selected (memory A3
5150), and if it is selected, operates the selector 98, and VDB is set to memory B (5150).
MB). (S151) IζMU stores the image data in the memory according to the gate selection. FIG. 17(f) shows the flow of the monitor mode operation. l
After receiving the monitor operation specification by the user's operation keys, 7 MU selects 2 memories (8153), specifies the number of sheets (8154), and inputs the start key (8155).
Starts the monitor operation. Memory selection (S153
) is the original 66 'I: Selecting which memory to store data in. There are choices of memory A, memory B, and memory AB.

After the start key is input, the RMU

is operated to output the image (III) of memory A (MA) as VDA (S160).

On the other hand, if it is not selected, the selector 92 is operated and the image 18! of memory B (MB) is selected. is output as VDA (8161).

Next, it is determined whether the memo IJB is selected (8162), and if it is selected, the selector 93
is set to 1, and both sections of memory B (MB) are output as VI) B (8163). If it is not selected, the selector 93 is operated to output the image of memory A (MA) as VDB (S1
