Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an image processing system that processes image information.

[Prior art]

Conventionally, various devices for recording, storing, and communicating image information have been developed and put into practical use. Although such a device has been used as a single-function device, it has little practicality as a device that organically combines various functions.

However, no configuration is shown in which the document image recorded in the recording unit is monitored by the display unit, and furthermore, a configuration in which image data stored in the storage unit is transferred at high speed to the display unit is not shown.

In addition, Japanese Patent Application Laid-open No. 49-131317 discloses that image data that has been edited according to instructions for a desired editing process and stored in a storage unit is transferred to a storage unit based on a line synchronization signal, A configuration is shown in which a recording unit records a printed original image on a recording material.

However, like the one described in the above-mentioned Japanese Patent Application Laid-Open No. 52-108822, there is no disclosure of a configuration in which the display unit monitors the original image stored in the storage unit. A configuration for transferring image data to the display section at high speed is also not shown.

〔Example〕

FIG. 1 shows an embodiment of a printer device to which the present invention is applied. 53 is the main body itself. Reference numeral 45 is copy paper, and in principle there is no need to be particular about the quality of the paper, and although cut paper is stored in the cassette storage section in this drawing, it is also possible to use roll paper and cut it after recording. 44 indicates a developer supply device and a developer. This developer is called a photoconductive toner. Normally, due to the internal polarization within the toner particles, the surface remains charged (therefore, it appears to be in the same state as magnetic toner), and when light is applied to it, the surface The polarization of the charges on or inside and the charges of different polarity inside disappears,
The principle is that charge disappears from the surface. This principle and application are disclosed in Japanese Patent Application Laid-open No. 53-
111733 (Ricoh) etc.

FIG. 2 shows the principle of applying this toner to generate character patterns. First, when the photocontoner is dispersed over the entire surface of copy paper and light is applied thereto only to the positions corresponding to the character patterns, that is, the dark areas, the charge disappears only at the character patterns.
In the next step, a reverse charge is applied to the toner surface of the copy paper, and at the same time, charged toner other than the character pattern is removed by a suction blower. However, at this time, some of the uncharged toner in the character pattern area is also removed by the suction blower, so by applying a charge of the same polarity as the charged toner from the back side of the copy paper, the charged toner can be separated better and the uncharged toner can be removed. It is necessary to take measures to increase the adsorption of toner to copy paper.

Returning to Figure 1 again. 19 is based on the above principle,
A laser device that scans text or picture patterns using a raster scan method using a semiconductor laser beam using a video signal given from an external device to photocontours uniformly distributed on copy paper. Reference numeral 46 denotes a cleaner device and a suction blower, which are used together with a charger 47 and a charger 52 to remove the charged toner on the copy paper in order to develop the character pattern created by the laser device 19. Reference numeral 48 indicates uncharged toner remaining on the copy paper corresponding only to the character pattern portion, and 51 indicates a pressure fixing device, which fixes the toner on the copy paper with a pressure of about 30 kg/cm. Reference numeral 49 denotes a tray from which the copy paper produced in this manner is discharged.

(Other variations) Figure 3 shows a simple printer device that uses an external video signal to scan the toner uniformly distributed on the copy paper, and uses the light energy of a laser beam to burn and fix the toner on the copy paper at the same time. ing. Reference numeral 44 shows a developing device that uses a single-component magnetic toner similar to the conventional one and houses it. The laser device 19 is a CO ₂ laser device that can obtain a high enough output to fix the toner. A cleaner device 46 has a suction blower and a charging device with a polarity opposite to that of the magnetic toner, and this charging device creates a state in which the magnetic toner other than the character pattern already fixed by the laser can be easily separated from the copy paper. , the toner is removed by a suction blower. Therefore, in the state 48, a fixed visual image is already obtained on the copy paper.

(Application Example) Below, an application of the information transmission device of the printer as a receiver will be described.

FIG. 4 shows an outline of the mechanical configuration. The image information transmitted from the public corporation line is received by the receiver and temporarily stored in the memory device. The memory device may be a fixed head disk memory or a semiconductor memory. Next, when the appropriate amount of information is stored in the memory device, the information is outputted from the memory device to the laser device in synchronization with the copy paper feeding speed of the printer device, and the copy paper is irradiated with laser light. Here, we will explain why the information received from the public corporation line via the receiver is not input directly to the laser device, but is first inputted via the memory device.
As is well known, the information propagation speed of public company lines is approximately
While the maximum speed is 3KHz, the linear speed of the copy paper of this printer can be 100mm/sec or more. If A4 paper is transported horizontally at a linear speed of 100 mm/sec, the writing speed of the laser beam is 1 ÷
(100mm/sec) ÷ 2352bit = 4μsec/bit = 250KHz. The breakdown of this 2352bit is A4 width 294mm x 1
Number of picture elements per mm = 2352 bits. Therefore, the receiving speed
The writing speed is 250KHz, which is about 83 times faster than 3KHz, so the procedure is to first store it in the memory device and then write it. In addition, in this application example, as described later, the transfer of image information within the device and the control of the device, that is, the operation commands, are performed via a common bus line, so the operation commands are sent from the CPU to each function within the device. During this time, the image information is saved in the memory device. Therefore, the memory device in this application example has the role of matching the transfer speed of the public corporation line with the speed of the printer device, and as a saving means for sharing the bus line. Furthermore, such a combination of a printer device and a memory device has the effect that it is possible to copy one or more arbitrary sheets by one reception. Furthermore, once received information can be stored for a long period of time if necessary, and it is expected that any number of copies can be made offline as needed during free time on the public corporation line.

FIG. 5 shows a specific circuit configuration of the device shown in FIG. 4. The control of this device is mostly performed by the judgment and commands of the CPU 1. When CPU1 is on standby,
It monitors the key inputs from the operator on the operation unit 21 and outputs the input to the display 22 via the operation/display control unit 4, and also monitors the status within the printer device via the printer control input/output unit 3. I'm going. If an abnormal condition is detected within the printer device, it functions to output to the display 22 through the operation/display control section 4 and warn the operator. Furthermore, the presence or absence of a calling signal (16 Hz) from the public corporation line 20 is monitored via the line switching section 6 and the line switching control section 5. If the CPU 1 detects this 16 Hz calling signal, it instructs the line switching control section 5 to switch between FAX/TEL, and the line switching control section 5 causes the line switching section 6 to maintain the FAX mode. Then, the CPU 1 transmits a confirmation signal confirming that the signal has been received to the other party via the response signal sending section 11, the modulation circuit 10, and the line switching section 6. Next, since a model mode signal is sent from the other party, it is detected through the line switching section 6, the demodulation circuit 8, and the response signal detection section 12. After that, if there is no problem with the phase matching, a reception ready confirmation signal is sent to the response signal sending section 11, modulation circuit 10, and line switching section 6 as described above.
Send it back via the following route. Thereafter, the input image information is stored in the memory device 18 via the demodulation circuit 8, the modem control section 7, and the DMA control section 15. Thereafter, when the response signal detection section 12 detects the message end signal, a message confirmation signal is sent back to the other party via the response signal transmission section 11, modulation circuit 10, and line switching section 6 route. At this point, the CPU 1 starts the timer 17, and if the model mode signal from the other party is not detected by the response signal detection unit 12 within a certain period of time, the CPU 1 starts the timer 17.
The CPU 1 instructs the line switching control unit 5 to disconnect the line. Next, the CPU 1 starts up the printer device, transports the copy paper, and when it detects that the leading edge of the copy paper coincides with the optical axis of the laser, drives the laser, and when the laser beam horizontal synchronization signal is detected, The CPU 1 releases the bus and hands it over to the DMA control units 15 and 13. Then, image information for one line in the memory device 18 is transferred from the memory device 18.
The data is output directly from the memory device 18 to the laser in sequence through the route of the DMA control units 15 and 13 and the laser device 19. When the output of one line of information is completed, it waits for the laser beam horizontal synchronization signal to be input again, and after detection, the same operation as above is performed again. Printout is completed in this way.

To summarize the above, when the response signal sending section 11 and the response signal detecting section 12 receive image information,
It is also a response control unit for mutually confirming with the other party when reception is complete, and corresponds to a pre-processing and post-processing unit. The modem control units 7 and 9 control the modulation and demodulation of image information, and the line switching control unit 5 controls the modulation and demodulation of image information.
This is where FAX/TEL line switching and maintenance control is performed.

Furthermore, a copying and information transmission device will be described as another application example.

FIG. 6 shows an outline of the mechanical configuration.

When using it as an offline copier, 3.
Reference numeral 9 denotes a document table, and 40 an optical system consisting of a lamp, a reflector, a plane mirror, a lens, a photodiode array, and a driving function. The image pattern irradiated by the lamp is imaged onto a photodiode array 41 via a mirror and a lens. Therefore, by scanning the original on the original table 39 with the optical system 40, an image pattern is sequentially formed on the photodiode array 41. This image pattern is photoelectrically converted by the photodiode 41 and output as a serial signal, so when this signal is directly input as a video signal to the laser device 19 in synchronization with the movement of the copy paper, the scanning pattern by the optical system 40 is is formed on the copy paper.

In the transmission mode, the scanning speed of the optical system 40 and the conveyance speed of the copy paper are constant because the copying function is also provided. Therefore, this speed is similar to the previous application example.
Since the serial signal is 100 mm/sec, which is significantly faster than the transmission speed of the public corporation line, it is stored in the memory device 18 and then transmitted sequentially via the transmitter 42.

When in reception mode, it is similar to the application example of the information transmission device as a receiver, and image information from the public corporation line is stored in the memory device 18 via the receiver 43.
After that, it is output to the laser device 19.

Furthermore, since the medium for transmitting image information and sending operating instructions for each part is common during transmission and reception, the memory device 18 is required to store and save the image signal converted into an electrical signal in the memory device. used. Furthermore, since the reception does not have to be performed simultaneously with the photoelectric conversion of the information image, it has the function of receiving and storing image information in a single function, and by using a multi-section memory device, it is possible to store several pages of information. It also has a function to memorize and retrieve and print out when necessary.

FIG. 7 shows a specific example of the circuit configuration of FIG. 6.
The control of this device is mostly performed by the judgment and commands of the CPU 1.

During standby, after the power is turned on, the CPU 1 connects the reader unit (that is, the optical system) through the input/output unit 2 for controlling the reader unit and the input/output unit 3 for controlling the printer unit.
The state of each printer section is detected, and when an abnormality is found, a warning to that effect is generated on the display section 22 via the operation/display control section 4. It also accepts commands from the operator via the keys of the operation section 21 and the operation/display control section 4, and responds the results to the display section 22 via the operation/display control section 4. Furthermore, the presence or absence of a calling signal (16 Hz) from the public corporation line 20 is monitored via the line switching section 6 and the line switching control section 5. Regarding the priority of mechanical movements, first of all,
Give top priority to abnormal situation handling. For example, when the reader unit control input/output unit 2 determines that the optical system 40 is not at the home position, priority is given to driving the optical system motor and reverse clutch to return it to its home position. Further, if the printer section control input/output section 3 determines that there is no copy paper or toner and displays it, priority is given to waiting for the operator to complete the operation of replenishing copy paper and toner. During this time, copy commands from the operator's operation keys,
Otherwise, the transmission command is not accepted, and the CPU 1 instructs the line switching control unit 5 to switch the line switching unit 6 to the TEL side, and prohibits reception of the reception mode. Next, the modes include copy operation, retention copy operation, transmission mode, reception mode, etc., and if any one of these modes is accepted, the other modes will not be accepted until the previously accepted mode is completed.

Other application examples are described below. If a paper jam or copy paper runs out inside the printer that occurs while image information is being received and printed, the operation of the printer will be stopped, but the image information that is being received will remain in that state, rather than completely prohibiting reception. is continued and entered into the memory device. In other words, the operation of CPU1 in response to the paper jam or out of copy paper is as follows:
Since the display section 22 only displays the information and stops the printer, a flip-flop is provided for the paper jam or copy paper out display function of the operation/display control section 4 and the stop function of the printer section control input/output section 3. The command of the CPU 1 is only to generate one pulse, and therefore, the shared bus line is used only for the time of that pulse, and there is no problem with the image information being received. Therefore, the image information being received is stored in the memory device regardless of the operation of the printer device.
After the abnormal state of the printer device is resolved, it can be printed out by outputting again from the memory device.

When using as an offline copier
When the CPU 1 receives a copy command from the operator via the operation/display control unit 4, it controls the motor, paper feed, and HTV to the input/output unit 3 for controlling the printer unit, and the input/output unit 2 for controlling the reader unit. Then, when the leading edge of the copy paper passes the registration sensor, a command is sent to the reader control input/output section 2 to turn on the forward clutch and halogen lamp, and the optical system is activated. When the document begins to move forward and passes the front end sensor of the document platen, the photodiode control signal is turned on, and the laser is turned on for the input/output section 3 for controlling the printer section. When the laser beam horizontal synchronization signal is detected from the printer control input/output section 3, the CPU 1 releases the bus and passes control to the DMA control sections 13 and 14. Thereafter, the serial image signal generated from the photodiode 41 is sent to the DMA controller 14.
The signal is passed directly to the DMA control unit 13, and this becomes a video signal to the laser device 19, which writes an image pattern onto copy paper.

In the transmission mode, when the operator presses the transmission mode selection button from the operation keys, the CPU 1 sends the line switching unit 6 to the line switching control unit 5 to send the FAX/
Instructs to change TEL to TEL. The operator then dials the other party. After that, a confirmation signal from the called station is sent to public company line 2.
If the line switching unit 6, demodulation circuit 8, and response signal detection unit 12 detect the signal from 0, the operation/display control unit 4 displays a message on the display unit indicating that the transmission command key may be pressed. The operator sees this and presses the transmission command button.

After that, when the CPU 1 receives a transmission command from the operator via the operation keys in the operation/display control unit 4, it instructs the reader unit control input/output unit 2 to operate the optical system motor, halogen lamp, and forward clutch. When the document starts moving and detects the document leading edge sensor, it issues an operation command to the photodiode array, and at the same time, the CPU 1 releases the bus, and the DMA controllers 14 and 1
5, and transfers the signal from the photodiode to the memory device 1 via the DMA controllers 14 and 15.
8 sequentially in real time. After that, when the inverted position of the optical system is detected, the bus is transferred to the CPU again.
1 side, the CPU 1 instructs the reader unit control input/output unit 2 to turn off the forward clutch, turn on the reverse clutch, return to the home position, and turn off all controls. Thereafter, the response signal sending unit 11 transmits the model mode signal and the phase signal to the other party via the route of the modulation circuit 10, line switching unit 6, and public corporation line 20, and the other party sends a reception ready signal, and from the public corporation line 20 to the line switching unit. 6. When detected by the demodulation circuit 8 and the response signal detection unit 12, the CPU
1 transmits the information stored in the memory device 18 sequentially from the memory device 18 through the route of the DMA control section 15, modem control section 9, modulation circuit 10, line switching section 6, and public corporation line 20. After the transmission is completed, a message end signal is sent from the response signal sending section 11 through the modulation circuit 10, the line switching section 6, and the public corporation line 20, and a message confirmation signal is sent from the other party to the public corporation line 2.
If the response signal detection unit 12 detects the signal from 0 through the line switching unit 6 and the demodulation circuit 8, the operator is notified of the completion via the operation/display control unit 4 on the display unit, and at the same time, the timer 17 is activated. . After the timeout, a line disconnection command is issued to the line switching control section 5, and all transmission modes are terminated.

Since the reception mode is the same as the application example of the information transmission device as a receiver, the explanation will be omitted.

Retention mode is a method in which information that remains in the memory device 18 when previously received is output later as needed. When the operation/display control section 4 detects that the operator has pressed the retention key, the motor, paper feed solenoid, HTV, blower, etc. are turned on for the printer section control input/output section 3. When the copy paper starts to move and is detected by the registration sensor, the laser is turned on, and when the resulting laser beam horizontal synchronization signal is detected, the CPU 1 releases the bus and transfers data from the memory device 18 to the DMA control units 15 and 13.
Writing the contents of the memory device 18 directly to the laser via DMA. These movements therefore form an image pattern on the copy paper.

Furthermore, by having the memory device, information scanned from a document or received by a communication means and inputted into the memory device 18 can be arbitrarily transmitted during idle time of the public corporation line; Also, the reception time can be determined at any time during the idle time of the public corporation line by means of storing the information in the memory device, which is a function of the printer device. Further, the memory device 18 may have a function of storing a certain number of image information by having several storage locations. In this case, it is also possible to send, receive, or print out several pieces of information at the same time.

Another application example is an application as a printer from an intelligent terminal having a CRT.

The intelligent terminal refers to an automatic search device, a computer, an office computer, a word processor, etc., each of which has a general appearance as shown in FIG. In other words, CRT33 and keyboard 25
interact with the operator and process information/data. Also, if necessary, information/data is stored on the disk 23 and retrieved. Furthermore, when satisfactory information/data is displayed on the CRT33, the operator presses the keyboard 2.
The system is designed to output the contents to the printer device according to the command from 5.

FIG. 9 shows a specific example of the circuit configuration.

All control is performed mainly by CPU1.
The CRT 33 displays 32 characters horizontally and 32 characters vertically, and each character is displayed as 5 x 7 dots.

Regarding the control of CRT33, the information that should be displayed on the entire screen (32 x 32 characters) is usually RAM2
9 is stored statically. CRT3
The synchronization timing for displaying on the screen No. 3 is generated by the synchronization signal generation circuit 34. Typically, multiplexer 30 selects signals from synchronization signal generation circuit 34 rather than from the bus. Then, by the address signal from the synchronization signal generation circuit 34,
The contents of the RAM 29 are sequentially read out and input to the character generator 31. On the other hand, a character pattern column selection signal is inputted from the synchronization signal generation circuit 34 to the character generator 31, so that a bit pattern corresponding to each column is output from the character generator 31, and a video signal is generated. The signal is input to the circuit 32. Therefore, since the character pattern is composed of 5 x 7 dots, the character data at a certain address in the RAM 29 is called to the character generator 31 seven times, and the output from the character generator 31 is 5 bits in parallel. It will be. The video signal generation circuit 32 is a circuit that converts this 5-bit parallel signal into a serial signal, and its output is sent to the CRT 33.
It becomes a video signal.

Next, we will discuss key control. When the CPU 1 detects a key input from the keyboard 25 with the keyboard control unit 26, it inputs the code to the buffer 28, and when it detects that the end key of the character string has been input, it decodes the command and processes the information/data. Then, the result is written to the RAM 29 via a route from the buffer 28 to the RAM 29 and displayed. Of course, the codes keyed into the buffer 28 are sequentially entered into the RAM 29 and displayed.

To access files on the floppy disk, use the keyboard 25 to access the disk 23.
If you want to display the file above, select disk 23.
From the floppy disk control section 24, buffer 2
8. Written to RAM 29 via the RAM 29 route. Also, conversely, the information on CRT33 is transferred to disk 23.
When it is desired to file the data, it is written from the RAM 29 through the buffer 28, floppy disk control section 24, and disk 23. Also, direct RAM29
Since it is written to disk 23 from
6 and move it to disk 23 or RAM 29.
You can read/write.

Furthermore, when outputting the information/data on the CRT33 to a printer device, the scanning speed of the CRT33 is several hundred Hz, while the writing speed of the printer device is several hundred KHz. Deploy it on the memory device. The method is to use a character generator 31
Parallel data output from CRT33 horizontal/
Character generator 31, DMA control unit 27, 1 while keeping timing with vertical synchronization signal
5. Write at the root of the memory device 18. After the writing is completed, the CPU 1 instructs the printer unit control input/output unit 3 to drive the printer device, and at the same time, the DMA control units 15, 1 are sent from the memory device 18 under DMA control at the timing of registration with the copy paper.
3. Write using the route of the laser device 19. Since the following operation is similar to the retention operation in the application example described above, the explanation will be omitted.

Furthermore, as another application example, an information retrieval device shown in FIG. 10 will be described. This is an information retrieval device that searches offline and prints out the contents of magnetic cards and disks that store files generated by office computers, computer word processors, etc. FIG. 11 shows a specific example of the circuit configuration. When the operator inputs the name of the file to be printed and its attributes using the keyboard 21,
For the floppy disk control unit 24, the CPU 1
After searching for the corresponding file name and developing its contents from the disk 23 via the floppy disk control unit 24 onto the program + data memory 16, the data on the memory 16 is transferred to the character generator 35. through
A character is written into the memory device 18 via a route between the DMA control unit 15 and the memory device 18 as a signal in which characters are broken down into bit patterns. After writing, the CPU 1 issues a copy operation command to the printer control input/output unit 3, and when the copy paper and the register are separated,
When the laser is turned on and the resulting laser beam horizontal synchronization signal is detected, the CPU 1 releases the bus and sequentially controls the memory device by DMA control from the memory device 18 through the DMA controllers 15, 13 and the laser device 19. The content of 18 is the laser device 19
is output to. The following is the same as the retention in the application example, so the explanation will be omitted.

Furthermore, as another application example, a device called a graphics processor will be described.

Information can be broadly classified into two types. One type of information is images, which are information that humans can intuitively understand, and the other is data, which is information that computers can understand. On the other hand, there are communication and processing as means for these. There is a facsimile as a device in the image communication field, a word processor in the data communication field, and a computer as a device in the data processing field. Here, we propose a device that performs image processing under the name of a graphics processor. This device is a device that processes images as they are, such as superimposing, compositing, and
This is a device that performs trimming, enlargement, reduction, position conversion, etc. Furthermore, as will become clear from the following description, the above processing is accomplished by computer means, and is equipped with a keyboard and CRT display for interaction with the operator, information storage, and file storage. Since the configuration can be developed to be equipped with a floppy disk or the like for general use, it is possible to provide a new information processing device that performs all image communication and processing and data communication and processing.

FIG. 12 shows a device according to the invention.

Reference numeral 38 denotes a reader section which is a device for setting an original and reading the image thereof. Reference numeral 37 denotes a controller section that performs all controls of this device. 33 is the leader section 38
A CRT is a device that displays images read by a computer.
Reference numeral 25 denotes a keyboard section through which the operator, while looking at the display on the CRT 33, issues instructions for image processing such as image superimposition, composition, trimming, enlargement, reduction, position conversion, and copying. 19 is a printer device that prints out the contents of the CRT 33; The document size handled by this device is A4 only, and one pixel is
It is decomposed into 8bit/mm. Therefore, 210mm x 8bit = 1680bits for A4 horizontal direction, 294bits for A4 vertical direction
Since it is decomposed into mm x 8 = 2352 bits, the CRT screen is also decomposed into 1680 dots horizontally and 2352 dots vertically. Also, the VIDEO-RAM that stores this information is also 1680×
I am using one with a size of 2352bits. FIG. 13 shows a specific circuit configuration.

First, the read command from the keyboard 25 is sent to the CPU.
1, it commands the reader section control input/output section 2 to start the optical motor, halogen lamp, and forward clutch. Next, the optical system 40 starts moving, and when it detects the document leading edge sensor, it starts the photodiode array, and at the same time, the CPU 1 releases the bus.
Exchange of signals between DMA control units 14 and 15
This can be done using DMA control. The image signal received by the photodiode array 41 is input into the memory device 18 through an image amplifier. The scanning speed of the optical system 40 at this time is the same as in the previous examples.
Therefore, the transfer speed can be considered to be very high. Next, when reading for A4 size is completed and the optical system 40 reaches the A4 reversal position, the halogen lamp and forward clutch are turned off, and the reverse clutch is started. Then, when the optical system 40 reaches the home position again, the reader unit control input/output unit 2
command to stop all equipment.

Next, the CPU 1, in order to display the image signal just read into the memory device 18 on the CRT 33,
It is necessary to expand to VIDEO-RAM 29 at high speed. For this purpose, CPU1 releases the bus again and uses DMA
The control units 15 and 36 are set in a state where information can be transferred by DMA. This is executed continuously by command keys from the keyboard 25 or by program commands from the program+data memory 16. As a result, one page on the memory device 18, that is, 1680×
The 2352-bit information is sent to VIDEO via the DMA control unit 15, 36, buffer 28, and VIDEO-RAM 29 route.
- Expand on RAM29. Of course, at this time, the address multiplexer 30 selects the address of the DMA control unit 36 and specifies the RAM 29. First, the information written in the RAM 29 is transferred to the video generation circuit 32 in sequence in synchronization with the timing signal generated by the synchronization signal generation circuit 34, regardless of the movement of the CPU 1. Displayed on CRT33 as a serial VIDEO signal. Of course, at this time, the address multiplexer 30 functions to select an address from the synchronizing signal generating circuit 34 and designate it in the VIDEO-RAM 29. Here, it is assumed that the memory device 18, which is a buffer memory, has one or more pages (1680×2352×n pages).

This device has a program + data memory 16 that contains commands for image processing such as image superimposition, composition, trimming, enlargement, reduction, position conversion, and copying.
It is prepared for you. For example, in the case of inserting character/numeric information typed by an operator into a part of an image pattern, a key code inputted from the keyboard 25 is transferred from the keyboard 25 to the keyboard control unit 26 and the program + data memory 1.
6 route, it is stored in the program + data memory 16, and the image processing command is executed from that character string.
If the CPU 1 decodes it and it is a composite trimming command, it determines that the character/number string that follows is the information to be inserted, calls up the character codes one after another, passes them through the character generator 35, and converts them into a bit pattern. Next, the memory device 18
The command operation is completed by specifying the address to be accessed and transferring the signal converted to the bit pattern thereto.
Immediately after completion, the contents of the memory device 18 are transferred to the RAM 2 so that the operator can check them on the CRT 33.
9 using the same procedure as above.

That is, the image information read from the reader device is photoelectrically converted and then stored in a predetermined first section of the memory device 18. After that, CRT33
It is sent to RAM 29 for display on the top.
The RAM 29 performs image processing according to preset image processing information such as compositing and trimming from the program + data memory 16 that stores control signals used for image processing, that is, instruction information for trimming position, size, and compositing position, etc. Image processing is performed in accordance with key input commands or automatically by the CPU 1, stored in a predetermined storage section such as compositing in the memory device 18, and displayed on the CRT 33. after that,
Information for compositing with the processed image is input from the keyboard 25, and a compositing command is also input from the keyboard 25. This keyboard 25
The synthesis information from is stored in a third section of the memory device 18 different from the above, and is further transmitted via a character generator 35 from the memory device 18,
The image information is converted into image information for display on the CRT 33 and stored in the memory device 18 again. And this information is similar to the information read from the reader.
The image data is sent to the RAM 29 and synthesized at a predetermined location in accordance with the control signal output from the program+data memory 16, similar to the processing of the image information. This combined information is then displayed on the CRT 33, and the trimming and combination of the read information and the keyboard input information is confirmed. Therefore,
The memory device 18 contains the tring and the CRT after the synthesis.
This means that the same image information as the image displayed at 33 is stored in memory.

Combining, adding, and modifying image information from a floppy disk and information from a keyboard as a communication device and storage device, as shown in the following application examples.
In processing such as trimming, image processing is performed using the multi-section memory device 18 in the same manner as in the case of reader reading, and composition etc. are performed in accordance with control signals set in advance in the program + data memory 16 in the RAM.

In addition, the combination location is program + data memory 16
This can be done either by changing the semi-fixed data regarding the location, or by using the key when operating the keyboard 25 to give an approximate location designation.

Next, when the CPU 1 determines that the operator has input a copy command from the keyboard 25,
The CPU 1 is connected to the input/output section 3 for controlling the printer section.
Issues a start command to the motor, paper feed solenoid, HVT, blower, etc. When the copy paper is conveyed and the registration sensor is detected, a laser start command is issued and the resulting laser beam horizontal synchronization signal is detected, and the CPU 1 releases the bus.
Consideration is given so that information can be directly transferred between the DMA control units 15 and 13 by DMA control. As a result, one page's worth of image information in the memory device 18 is outputted to the printer device at high speed in synchronization with the process speed of the copy paper. The copying operation is completed by the above operations. Other application examples are shown below.

〔Effect of the invention〕

As described above, according to the present invention, the first transfer means DMA-transfers the image data that has been edited and stored in the storage means to the display means according to the instruction of the desired editing process; Since it has a separate second transfer means that DMA-transfers the stored image data to the recording means based on the line synchronization signal from the recording means, the image data can be supplied without any special timing restrictions. Not only does it transfer image data to the display means using DMA transfer, but also to the recording means, which must supply image data in synchronization with the recording of each line of the image.
DMA transfer makes it possible to transfer image data at high speed.

Furthermore, the first transfer means DMA transfers the image data stored in the storage means to the display means after the editing processing by the processing means is completed, so that the edited manuscript image can be quickly displayed by the display means. On the other hand, since the second transfer means DMA transfers the image data stored in the storage means to the recording means after receiving an instruction to record the image, the second transfer means transfers the image data stored in the storage means to the recording means. It becomes possible to selectively record only necessary original images on the recording material by the recording means.
