Abstract

PURPOSE:To process picture information easily and quickly, by storing the picture information from a line once in a memory device, and transferring the information from the memory device to a picture processing means while sychronizing the stored signal with the operating speed of the picture processing means. CONSTITUTION:After the completion of reception preparation, picture information of N-line to be inputted is transferred in DMA via a demodulation circuit 8, an MODEM control section 7, and a DMA control section 15, and stored in a memory device 18. When a message completion signal is detected at a response signal detection section 12, the signal is returned to the caller from a response signal transmission section 11 and a CPU1 instructs the cutoff of the line to a line switching control section 5 after the operation of a timer 17. The CPU1 starts a picture processing means including a laser 19, and releases a bus when a laser beam horizontal synchronizing signal is detected and gives the bus to DMA control sections 13, 15. The picture information for one line's share in the memory device 18 is sequentially outputted to the laser 19 directly, and after the end of operation of one line, the output of information for N-lines'share is outputted repetitively as a picture.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image processing system that performs IkI conventional information processing.

2. Description of the Related Art Conventionally, various devices for recording, storing, communicating, and synthesizing th image information have been developed and put into practical use.

However, this poor device is often used as a single-function device, and there is little possibility of realizing it as a device that organically combines these four functions. ,Also.

Visually capturing and processing information as image information improves office efficiency, and therefore there is a desire for a device that can easily and quickly process various types of image information. There is.

The object of the present invention is to provide a novel conventional processing system that strictly addresses the above points. Another object of the present invention is to provide an art processing system having multiple functions for image processing. Yet another object is to provide an image processing system having means for saving information during transmission in a predetermined operating state.

FIG. 1 shows an embodiment of the printer device used in the present invention.
53 is the main body itself. 45 is copy paper and 9
In principle, there is no need to be particular about the paper quality, and 9 drawings can be used for #
'I store the cut paper in the cut storage section,
A system in which 0-l paper is used and is cut after recording may be used. Reference numeral 44 indicates a developer supply device and a developer. This developer is the basis of the present invention, and is called a photoconductive toner.Normally, due to internal polarization within the toner particles, the surface maintains a normal state of charge of ■ or θ. Therefore, it appears to be in the same state as magnetic toner. 】、When light is applied to this, the surface improves■
Or the polarization of the θ charge and the internal different polar charges 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 a single character pattern. First, when the above-mentioned photocontoner is dispersed on the upper surface of a 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 sucker. However, at this time, some of the non-charged toner in the character pattern area was also removed by the suction blower, so the back side of the copy paper #7.
# It is necessary to devise ways to improve the separation of the charged toner and improve the adhesion of the uncharged toner to the copy paper by applying a charge with the same polarity as the charged toner.

Return 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 source, which uses a video signal given from an external device to photocontours uniformly distributed on copy paper. Reference numeral 46 indicates a cleaner device and a suction prower, which remove the charged toner on the copy paper by using a combination of the FE Teidenki 47 and the charger 52 to develop the pattern scanned by the laser device 19.

48 indicates a copy paper with uncharged toner remaining corresponding only to the character pattern portion; 51 indicates a pressure fixing device;
The toner remaining on the copy paper is fixed by a pressure of about 304/m. 49 is a tray for discharging the copies produced in this manner.

(Another modification example) Fig. 3 shows a simple printer device in which an external video signal is used to scan the toner uniformly distributed on the copy paper, and the source energy of the laser beam is used to simultaneously burn and fix the toner on the copy paper. It shows.

Reference numeral 44 shows a current device that stores one-component magnetic toner similar to the conventional one, and reference numeral 19 indicates a Cot laser device that can obtain a high enough output to fix the toner with a laser device. A cleaner device 46 includes a suction blower and a charging device having a polarity opposite to that of the magnetic toner.

With this charging device, magnetic toner other than the character pattern already fixed by the laser can be easily separated from the copy paper!
1 is made in advance and is to be obtained by a suction blower.

(Application example) Below, we will describe an application as a receiver of an information transmission device for a 1M printer.

FIG. 4 shows an outline of the mechanical configuration. The image information sent through the public corporation line 20 is received by the receiver 42, and is temporarily stored in the memory device fil8. This memory device 18Fi may be a fixed head disk memory or a semiconductor memory. Next, when the appropriate amount of information is stored in the memory device 1118, the information is output from the memory device [18] to the laser device 19 while synchronizing with the copy paper feeding speed of the printer device, and the copy paper is irradiated with laser light. do. ζHere, we will explain the reason why the information received from the public corporation through the receiver 42 is not input to the laser device 1119, but is inputted through the memory device 111it18.
As is well known, the information propagation speed of public company lines is approximately 31G1.
While z is MAX, the linear velocity of copy paper in a zero-print printer cannot exceed 100+w+/see. if.

When A4 paper is crumpled and fed horizontally at a linear speed of 100■/see, the laser beam cutting speed fFi is 1÷(100■/see).
see ) ÷ 2352 bits = 4 p sec
/bit-250PG (becomes z. This 2352bit
The breakdown is.

(A4 width 294 squares)
52 bit, thus for a receiving rate of 3 KHz.

Since the writing speed f = 250) G (z) has a speed ratio of about 83 times, the procedure is to store it in the memory device 18 and then write it. Also, in this application example, as described later, Transfer of iii1gII information in the device and control of the device, that is, operation commands, are performed via a common path line, so when one operation command is sent from the CPU to each function in the device, the image (mt'PI@ is the memory f111g. Therefore, the memory device 18 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 an evacuation means for sharing the pass line. Historically, such a combination of the printer device and the memory device 1B has the effect that it is possible to copy one or more arbitrary sheets by receiving - times. So, information once received can be stored for a long period of time as needed.

Must be 11! It is expected that the user will be able to copy any number of sheets according to their needs offline at any time when the public company line is free.

Figure 5 shows the gas circuit configuration of the device shown in Figure @4. The control of this apparatus is mostly carried out by the judgment and commands of a microcomputer designated as CPt)1, such as Intel Corporation's TOTA18086. When the CPU is on standby, it monitors input from the operator using the keys 21 and outputs information entered manually to the display 22 via the operation/surface control section 4, as well as monitors the status within the printer device. This is done via the input/output unit 3. If an abnormal condition is detected within the printer device, the condition ljA is outputted to the display 22 through the operation/display control section 4.

It functions to alert the operator. Furthermore, the presence or absence of a signal (16 Hz) from the public corporation line is monitored via the t-y line switching section 6 and the line switching control p5t-. If the CPUI detects this 16 Hz calling signal, it instructs the line switching unit #s5 to switch between FAX and FAX, and the single line switching control unit 5 causes the line switching unit 6 to maintain the FAX mode. Then, the CP'UI transmits a WA acknowledgment signal indicating that it has received the ejection signal to the other party via the response signal transmitting section 11.degree. demodulation circuit 89 and the leg switching section 6. Next, a model mode signal is sent from the other party, so 9 line switching unit 6. revenge 1
1111# Road 8. The response signal is detected through the response signal detection section 12t. Thereafter, if the 9 phase matching is not satisfied, a reception preparation completion confirmation signal is sent back via the response signal sending ill, demodulation circuit 8° line switching unit 6 route as described above. After that, the input N
The line 1Iiii image information is obtained by the demodulation circuit 8. Modem control unit 7. One magazine is transferred via the DMA control unit 15 and stored in the memory device [
Stored in 1B. after that.

When the response signal detection section 12 detects the message end signal, the response signal transmission section 11 returns a message confirmation signal to the other party. At this point, the CPU starts the timer 17, and the other party responds with a model mode signal within a time of 9M.
If the signal is not detected by the signal detection section 12, the CPUI instructs the line switching control section 5 to cut off the line. Next, the CPU issues a command #I to the printer device to transport the copy paper, and
When it detects that the tip of the copy paper is aligned with the original axis of the laser, it drives the laser and passes the laser. Then, one line of image information in the memory device 18 is transferred from the memory device 18 to the D
MA control s15°13 causes the laser device 19 to output directly from the memory device 18 to the laser 19 sequentially through the route. When the output of one line of information is completed, the iWJ waits for the laser beam horizontal synchronization signal to be input again, and after detection, the iWJ performs the above-mentioned special operation again. In this way, the printout is completed by repeating the output of 8217 pieces of information. (Refer to the flowcharts in FIGS. 31 and 32) To summarize the above, the response signal sending unit 11. The response signal detection unit 12 receives 5! of image information. A response control unit for mutual confirmation with the other party when transmitting data and when reception is complete.
In other words, it corresponds to the 11 processing and post-processing section. The modem control section 7 controls the transmission structure of information, etc., and the 1gl1i7I switching control section 5 switches the FAX/machine line.

This is where holding control iI is performed. j! ! Next, we will discuss a copying and information transmission device as another application example.

1 in Figure 6! An outline of the mechanical configuration is shown.

When using it as an offline photographic device.

39 is a document table, and 40 is an optical system with a lamp and electric resistance.

Consists of a plane mirror, lens, photodiode array, and drive function. The image pattern irradiated by the lamp is focused on a photodiode array 41 via a mirror and a lens.
# is done. Therefore, the scanning of the original on the original platen 39 by the optical system 40 is photoelectrically converted by the photodiode 41 and output as a serial signal.

When this signal 1 is directly input as a video signal to the laser device 19 in synchronization with the movement of the copy paper, an image pattern scanned by the optical system 40 is formed on the copy paper.

In the transmission mode, the scanning speed of the optical system 40 and the conveying speed of the copy paper are slow because the copying machine also functions as a copying machine. Therefore, this speed is 100 m/s as in the previous application example.
Since it is an EC, it is transmitted sequentially from the public corporation's circuit @20 through the transmitter 42t.

In the reception mode, it is similar to the application example of the information transmission device as a receiver, and 1llil image information from the public corporation line is sent to the memory device 18 via the receiver 43, and then outputted to the laser device 19.

Historically, when transmitting and receiving image information, the medium for transmitting the image information and the operation command for each part was common, so when the operation command for each part of the device was transferred, the image 1# signal, which was converted into an electrical signal, was stored in the memory device. The memory device 19 is also used for the need to save data.

If an urgent request to transfer image information occurs while image information is being transferred, it is also possible to evacuate the rthtta information currently being transferred and transfer the urgent information preferentially. be.

Furthermore, by temporarily storing the image information in the memory device 18, the image i! There is no need to do i. As a result, even if there is a failure in the image forming section such as the laser device 19, the
II.A hire system can be implemented. Furthermore, by using a multi-section memory device, it is possible to store several pages of information and retrieve and print out the information when necessary.

FIG. 7 shows a specific example of the circuit configuration of FIG. 6.

Control of this device is mostly performed by CPUI judgment and commands.

In standby mode, after the power is turned on, the CPU detects the status of the reader section (that is, the optical system) and printer sections through the reader section control input/output s2 and the printer section control input/output tB3, detects any abnormalities, and detects them when running. A warning to that effect is generated on the display section 22 via the operation/display control section 4. father.

Commands from the operator are accepted via the operation keys 21 and the operation/display control section 4, and the results are displayed on the display section 22 via the operation/display control section 4.

Furthermore, the calling signal' (16Hz) from the public corporation line 20
The presence or absence of this is monitored via the line switching section 6 and the line switching control section 5. Regarding the priority of mechanical actions,
Give top priority to abnormal situation handling. For example, when the reader section control input/output section 20 determines that the optical system is not at the home position, it drives the one-element system motor and reverse clutch.

- When it is determined that there is no paper or toner and it is displayed.

Priority is given to waiting for the operator to complete the operation of replenishing copy paper and toner. During this time, the copy command or transmission command from the operator's operation key 21 is not accepted, and the CPU changes the circuit switching unit 6 to the circuit switching control s5.
Instructs to switch to I and prohibits reception of reception mode.

Next, there are modes such as Fi, m-copying operation, retention-applying operation, transmission mode, and reception mode.

If one of these modes is accepted, the other modes will not be accepted until the first mode accepted is completed.

Other application examples are briefly described below. If a paper jam or copy paper runs out in the printer that occurs while image information is being received and printed, the operation of the printer is stopped, but the image information being received remains in that state, rather than completely inhibiting reception. is continued and entered into the memory device. In other words.

Moreover, it only stops the printer device.

Therefore, by providing a frig knob with a paper jam or copy paper out display function of the operation/display control s4 and a stop mechanism of the printer device, the command F' of the CPU
It is only necessary to generate 11 pulses. Therefore, the time during which the CPUI uses the path line shared for the transfer of self-incrimination information and the transfer of control commands is only the time of the pulse, and - image information reception 11! Therefore, the m-information being received is stored in the memory device [18] regardless of the operation of the printer device 19, and when an abnormal state of the printer device is resolved, the m-information being received is stored in the memory device [18] by outputting it again from the memory device. When receiving a copy command from the operator using the operation key 21, the printer unit control output, power 1 fls 3 V (vs. 1. motor, paper feed, HV
T't, also issues a command to the league club control input/output unit 2 to turn on the optical motor, i, CPU1t
When the leading edge of the i-copy sheet passes the registration sensor, it commands the league section control input/output section 2 to turn on the forward clutch and halogen lamp.

When the optical system begins to move forward and passes the sensor at the tip of the document platen, the photodiode control old issue is ONI! Then, the printer section control input/output section 3 is instructed to turn on the laser device. And if it detects the laser beam horizontal synchronization signal.

CPUI releases the bus and transfers control to DMA controller 13.1
Pass it to 4. Thereafter, a serial image signal is formed by the photodiode 41, and the signal is passed directly from the DMA control section 14 to the DMA control section 13, which becomes the video signal of the laser device 19.

Write the Yuu 1# pattern on the copy paper.

When in the transmission mode, the CPUI receives a transmission command from the operator using the operation keys.

The halogen lamp commands the forward clutch operation, and when the document leading edge sensor is detected, the photodiode array 41
At the same time as issuing an operation command to the DMA control unit 14.
The bus is passed to the photodiode 15, and the signal from the photodiode 41 is transferred to the memory device 18 via the control unit 14 and 15 and sequentially written in real time. After that, when the inverted position of the optical system is detected, the bus is transferred again to the CPU 11 [[L,
CPUUIJ-/W system [Turn off the forward clutch for the single-person output section 2 and turn on the reverse clutch, 'f
, orders the system to return to its home position and turn off all controls. Thereafter, the response signal sending unit H transmits the model mode signal and the phase signal to the other party via the public corporation line 20, and when the response signal detection unit 12 detects a reception ready signal from the other party, the signal is stored in the CPUIFi memory device 18. The information of N lines is sequentially sent to the model control unit 9. Modulation circuit 109 performs DMA transfer via line switching tone. memory 18
After the transmission of the N-line image information stored in is completed, a message end signal is sent from the response signal sending unit to the other party, and if the response signal detection unit 12 detects a message confirmation signal from the other party, the response signal 9 is displayed on the display unit 22. The timer 17 is activated at the same time as notifying the operator that the process has ended. After the timeout, a line disconnection command is issued to the single line switching control unit 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 previously received and stored in the memory device 18 is later output in accordance with the membership fee. When the operation/display control unit 4 detects that the operator presses the retention key provided on the operation unit of the device, the printer unit control input/output unit 3 controls the motor, paper feed valve, HVT, printer, etc. command to turn on. The copy paper begins to move.

When detected by the registration sensor, the laser is turned on, and when the resulting laser beam horizontal synchronization signal is detected, the CPU 1ti is released and information is transferred from the memory device 18 via the DMA control unit 15. and directly outputs it to the gt laser in the memory device 18. These movements create 1lkl fill on the copy paper.
A pattern is formed.

(Refer to Nos. 33 to 36, the flowchart diagram in the figure) Also, by having the memory device 18, the memory device 18 allows the information to be scanned from the original or received by the communication means.
It is possible to arbitrarily transmit the nine information entered in the public corporation line @20 during the free time, and furthermore, the time for receiving can be changed to the vacant time of the public corporation line 20 by means of storing it in the memory device, which is different from the printer device. can be received at will. Furthermore, the memory device 18 may be a multi-section memory having a function of being able to store 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 uses an automatic examination device, computer, office computer, and worddog 25 to communicate with the operator and process information/data. Also, if necessary, information/data is stored on the disk 23 and then retrieved. I! When satisfactory information/data is displayed on the CBr 43, the operator issues a command from the keyboard 25 to the printer device 1.
The system is designed to output the self-answers in 9.

FIG. 9 shows a specific example of the circuit configuration. All controls are CP
This is done mainly on the UI. CRT33Fi displays 32 characters horizontally and 32 characters vertically, and each character is displayed as IP5x7 dots.

Regarding the control of the CBr 33, the information (32×32 characters) to be displayed on the entire negative side is normally statically stored in the RAM 29.

A synchronization signal generation circuit 34 generates synchronization timing for performing all the displays on the CBr 33. Normal multiplexer
The signal from the synchronization signal generation circuit 34 is selected instead of the signal from the 30Vi bus. and synchronization signal generation circuit 34
The contents of RAM 29 ri#I are read by the address signal from
The first character is called and input to the character generator 31. On the other hand, the character fist generator 31 has -M
A character pattern column selection signal is inputted from the signal generation circuit 34, and thereby a bit pattern corresponding to each column is outputted from the character generator 31 and inputted to the image fjl M number generation 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 character data is
The output from the generator 31 will be output in s btt parallel. In the Eirin signal generation circuit 32, this 5 bi
tThis is a circuit that converts parallel signals into serial signals, and its output is CBr.
It becomes a video signal to 43.

Next, we will discuss key control. When the keyboard control unit 26 detects a key input from the CPU 1ti keyboard 25, the code is input to the buffer 28, and when it learns that the 1-character string Terminate key has been input,
It decodes the command, processes the information/data, and writes the results from the data bus buffer 28 to the RAM 29 for display. Of course, the loads manually entered into the buffer 28 are sequentially entered into the RAM 29 and displayed.

Regarding accessing files on the floppy disk 23, when you want to display a file on the disk 23 using the keyboard 25, the information security floppy disk control unit 24. Data bus buffer 28. R
It is written to RAM29VC via the AM2G route. Conversely, when you want to file the information on the CBr 43 on the disk 23, the tiRAM 29. The data is written to the disk 23 via the route of the data bus buffer 28 and the USB disk controller 624. Father, I write directly from RAM dan 29 to disk 23, so -Frog@Memory 16
Expand to disk 23 or RAM 29 READ/
You can also WRITE.

Also, when outputting the information '4@/ data on the CRT33 to a printer device, the scanning speed of the CRT33 is a few white hertz, whereas the writing speed of the printer device is several hundred KHz.
Hz, the information/data on the CRT 33 is once expanded onto the faster memory device. The method 10' uses parallel data tc output from the character generator 31.
It is written into the memory device 18 via the DMA control section 27.15 while keeping the timing with the horizontal/vertical synchronization signal of the RT 33. After writing is completed, the CPU instructs the printer unit control input/output unit 3 to drive the printer, and also controls the DMA control unit 15.13 from the memory device 1t18 at the timing of registration with the copy paper. The signal is output to the laser device i19 via the laser beam. Since the following operation is similar to the operation at the time of retention in the application example, the explanation will be omitted. (3rd
(See flowcharts in FIGS. 7 to 38) Furthermore, as another application example, an information retrieval device shown in FIG. 10 will be described. office computer.

This is an information retrieval device that searches offline and prints out the contents of a magnetic card or disk that stores files generated by a computer word processor or the like.

The circuit configuration is shown in FIG. 11. When a floppy disk operator inputs the name of a file to be printed and its attributes from the keyboard 21, the CPU searches the floppy disk control unit 24 for a file name that roughly corresponds to the file name, and if any is found. , after extracting the contents from the floppy disk 23 and developing them on the data memory 16, the data on the data memo January 6 is converted into pixel information via the character generator 35t, and then the DMA control section 15 After writing, characters are written into the memory device 18 as signals broken down into pitnos (turns).

The CPUI is for the input/output section 3 for controlling the printer section.

Issue copy operation command 1.゛When the copy paper and the resist are removed, the laser beam t-0Nt, and the resulting laser beam horizontal synchronization signal is detected, the CPU
releases the path and sequentially controls DMA from memory device 18 @1
The contents of the memory device 18 are output to the laser device 19 by DMA control via 5 and 13t. The following is the same as the retention in the application example, so the explanation will be omitted.

Another application example is a graphics processor!
Let's talk about l.

Information can be broadly classified into two types.

One of these is images as information that humans can intuitively understand.
#, and others are data as information that a computer can understand. On the other hand, there are communication and processing as means for these. And II! I11# There is a facsimile machine as a device in the communication field.

A word processor is a device in the data communication field, and a computer is a device in the data processing field. Here, we propose a device that performs uniform processing under the name "graphics processor." This device is image ill t-1
It is a device that processes images as they are (superimposition, trimming, and enlargement of 9g1IIl images).

This is a device that performs reduction, nine-position conversion, etc. It is also equipped with a keyboard and CRT display for interaction with history operators and for storing information.

Since it is possible to develop a configuration that can be equipped with a floppy disk, etc. for files, a new information processing device T- that performs all processing, data communication, and processing of data.
Can be provided.

FIG. 12 shows a device according to the invention.

Reference numeral 38 is a device for setting a document and reading its l1lliIl, which is a reader section. Reference numeral 37 denotes a controller section for controlling and turning off the apparatus. 33 This device is a CRT and displays the 1IIIiI image removed by the beam section 38. 25

FIG. 3 shows a specific circuit configuration according to the present invention.

First, when the CPU receives a read command from the keyboard 25, it commands the league unit 2 to start the optical motor, halogen lamp, and forward clutch. Next, the optical system starts moving, and when the document leading edge sensor is detected, the photodiode array 41 is started, and at the same time, the CPU releases the bus.

The received signals can be exchanged between the DMA i#IJ m sections 14 and 15 by DMA control. lI received with photodiode array 41! 1111/
! The signal is input to the memory device 18 through a single tell amplifier. The scanning speed # of the optical system 400 at this time is the same as in the previous example. Therefore, the transfer streak is extremely fast. Next, once the A4 size has been read and the optical system 40 is in the A4 reversal position, the halogen lamp and forward clutch are turned off.

Start the reverse clutch. And again, JT academic 40
When the device reaches the home position, it instructs the league control input/output section 2 to stop all equipment.

Next, CPIJI is used to display the image signal read into the memory device 18 on the t-CRT 33.

It is necessary to expand to VIDEO-RAM 29 at both speeds.

For that reason, the CPUI once again left the bus open.

The system is set up so that information can be transferred by DMA between the DMA control units 15 and 36. This is executed continuously by command keys from the keyboard 25 or program commands from the program memory 16. As a result, the information for one page on the memory device 18, that is, 1680 x 2352 bits, is transferred to the DM.
The data is transferred via DMA from the A control unit 15.36ty' to the tabular buffer 28 and expanded onto the VIDEO-RAM 29. Of course, at this time, address multiplexer 30FiD is selected and RAM 29f is designated. - The information written in the RAM 29 is synchronized with the timing signal generated by the synchronization signal generation circuit 34, regardless of the movement of the CPU
The self-dissolution of AM29 is sequentially transferred to the image generation circuit 32. Thereby, it is displayed on the CRT 33 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 the VIDEO-RAM 29. Here, the memory device 18, which is a buffer memory, has a capacity of one or more pages (1680×2352×n pages).

This device is capable of superimposing two images and trimming them.

expansion. A group of commands for performing image processing such as reduction, nine-position conversion, and copying are prepared in the program child data memory 16. For example, in the case of inserting character/a character information typed by an operator into a part of an image pattern, a key code typed from the keyboard 25 is inserted into the keyboard controller 26. Program child data memo is stored at the root of IJ 1 6, and from that character string n
If the CPUI decodes the image processing command 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 code in order, and passes it through the character generator 35 to generate bits. Make it into a pattern. Next, specify the address to be accessed for the memory device 18. By transmitting the signal corrected to the bit pattern thereto, the command operation is completed. Immediately after completion, the data is transferred to the iFfrRAM 29 of the memory device 18 in the same manner as described above so that the operator can check it on the CRT 33.

That is, the image information read from the league device is photoelectrically converted and then stored in the first section of a predetermined section 5' of memory device #18. After that, CRT33
It is sent to the RAM 29 for display on the top. RAM2
9, 1iii1jl processing information such as compositing, trimming, etc. from the program child data memory 16 in which control signals used for image processing are stored in advance. The image processing is automatically performed by the CPUIK according to the key human command VC, and the image information is stored in a predetermined storage section such as compositing in the memory device 18 and displayed on the CRT 33. be done. Thereafter, information to be synthesized with the thus processed image is input from the keyboard 25, and a synthesis command is also input from the keyboard 25. The composite information from the keyboard 25 is stored in the data memory device 16, and is further stored in the data memory device 16.
from the CRT 33 via the character generator 35.
The image information is converted into image information for display on the computer and stored in a predetermined section of the memory device 18. This information is then sent to the RAM 291C in the same way as the information read from the league.
Said il! Similarly to the processing of customary information, the data is synthesized at a predetermined location by a control signal output from the program child data memory 16.

And this was synthesized! The information is displayed on the CRT 33, and the trimmer/da 9 combination of the read information and the information input from the keyboard is confirmed. 1 degree, therefore, the memory device [1
At 8, the trimming and compositing are completed and the th is displayed on the CRT.
This means that the same image information as the groove is stored in memory. (
(Refer to the flowchart diagram in FIG. 39)) 9. Composition and addition of image information from a communication device and a floppy disk as a storage device and information from a keyboard as shown in the following application example.

Processing such as correction and trimming is also performed in the same manner as in the case of league reading, using the multi-section memory 18 and using control signals set in advance in the program memory 16.

The location for combining the helmet 9 can be changed by changing semi-fixed data relating to the location in the program memory 16, or by using keys on the keyboard 25 to specify the approximate location.

Next, when the CPUI determines that the operator has input a copy command from the keyboard 25, the CPUI issues a command to start the motor, paper feed solenoid, HVT, processor, etc. to the printer control input/output section 3Vc, and then sends the copy paper is transported and detects the registration sensor, issues a laser start command, and then detects the resulting laser beam horizontal synchronization signal.

The CPUI releases the path and takes care to enable direct information transfer between the DMA control units 15 and 13 by DMA control. As a result, image information for one page in the memory device 18 is outputted to the printer device at high speed in synchronization with the processing speed of the copy paper. The copying operation is completed by the above operations. Other application examples are shown below.

FIG. 14 shows a graphic processor of the application example shown in FIG. 12 which has an information transmission device and n disk-type memory devices built in, and performs 9 image and data processing 9 communications.

It has effects that can handle all functions such as generation, storage, and retrieval.

When copying the image (II), please use League Department 38. Public Corporation Line 2.
0. Alternatively, the image information obtained from the disk 23 is sent from the controller 37 to the printer section 19. After the information entered manually by the controller unit 37 in the process of the artist is developed on the CRT 33, corrections, additions, trimming, compositing, etc. are performed according to commands from the keyboard 25.

Then, the nine-(II) displayed on the CRT 33 is sent directly to the printer section 19 via the control section 37 and printed out.
Image processing is performed interactively using RT33. The information may also be transmitted to other devices via the public corporation network @20 or stored on the disk 23, if necessary. That is, when viewed from another angle, what is output to the disk 23 is storage.

Communication is output or input via the public corporation line 20. Search is the route from the disc to the CRT 33 to display the desired image information 1.

It is also possible to connect two or more leagues and printers to input and output image information at a plurality of installation locations.

FIG. 15 shows a specific example of the circuit configuration of this processor. This diagram shows the circuit in Figure 13 with the communication circuit in Figure 7 added, so the explanation is omitted. Figure 16 shows n leagues, n printers, and n units. It is a graphics processor that has a disk and further includes 9 communication devices.

This configuration allows leagues, printers, and disks to be installed as a pair in multiple locations.

Images read in the league and th stored on the disk
You can output me anywhere.

It is also possible to transfer image information to a disk at any location, and the transferred images can be printed out at any time. Furthermore, image transfer by transmission and reception can be performed from a plurality of installation locations.

Depending on the installation location, you may not need a league or a printer. In such a case, the device can be used effectively by combining the devices according to the requirements.
