Description

[Detailed Description of the Invention] ■Field of the Invention The present invention relates to character and symbol information (hereinafter referred to as text information).
A text information input board for inputting information, a line drawing information input means for inputting position information on a line diagram, an image reading device that reads an image and obtains pixel information (hereinafter referred to as image data), and converts this input information into instructions or instruction signals from a keyboard. Regarding an information processing device that centrally or decentrally combines a computer that processes and edits one document information, and a storage device such as a hard disk that stores document information, in particular, the storage of document information edited by this type of information processing device. (Record: File) Regarding processing.

■Prior art This type of conventional information processing device includes, for example, a text input board such as an input tablet, a kana-kanji input keyboard, a line drawing information input means such as a mouse, a cursor key, etc.
Image reading devices mainly based on CCD imaging devices, display devices such as CRT, storage devices such as hard disks as document storage devices (file memory), CPU, RAM, RO
Edited mainly by M.

It consists of a computer unit, a printer, etc., and these are either centrally located in one place or connected through communication lines and distributed.

Computer units 1~ are editing and storage processing means,
Normally, text and document creation, #W collection, collection, delivery, storage record: file), print 1-out, and transfer are controlled in accordance with the operation of function keys provided on the text information input board.

The computer unit ~ temporarily stores output data in the system buffer (RAM), and stores line drawing information (6 characters, symbol codes (text data), straight lines, 2 curves, etc.).
Vector data) and image reading information (image data: pixels) are stored in a work memory (RAM) in an arrangement according to the instructions of the input board, and document information (page information) consisting of a combination of these information is stored on the work memory. is temporarily stored in memory, document information is provided to a display device, and text and solid color data are converted into two-dimensional information (pixels) and displayed.

In other words, the document is displayed in two dimensions, similar to a hard copy. When recording is instructed, it is stored in a storage device such as a hard disk (file memory).

According to this information processing device, page-by-page document information in which input text data in text 1 to six board formats, input vector data from the line drawing information input means, input image data from the image reading device, etc. are arranged appropriately is edited and printed. The document is printed 1 to 1 according to the out instructions.
- and, if necessary, transferred to another location according to a transfer instruction. Further, when there is a transferred document, it is received, stored in the work memory and displayed, and is stored (file) in the hard disk in accordance with a recording instruction.

In conventional information processing devices of this type, document information is stored (file) for each document in a storage device such as a hard disk, but image data is generally
The number of documents that can be stored (number of document files) is large, and the storage area allocated to each document must be widened.
is limited to a small number of values, the storage area allocated for document information is likely to fill up quickly, and image information is redundant, so there is a large amount of information in one document. There is a problem that the access speed of the document file becomes slow and the storage capacity allocated to the document file increases. If the access speed is slow when reading documents, storing them, or transferring them, it is inconvenient that the operator, or if there is a boss or a transfer partner, has to wait for a long time, which ultimately reduces work efficiency. There is.

■Purpose The primary purpose of the present invention is to shorten the access time of document information in the processing of document information that is a combination of text data such as single characters and symbols, delineation information such as diagrams, and image data. A second purpose is to reduce the storage capacity allocated to information files.

In order to achieve the above object, in the present invention, the image data of the document information is stored outside the document file area allocated to the document storage (file) of a storage device such as a hard disk, and is stored in a storage area larger than the minimum storage unit of text data. Information that specifies this image data (management information), text data and line drawing information (solid data) is stored in large units (e.g., sectorless, track units), and information that specifies this image data (management information) is stored in the smallest storage unit of text data (e.g., sectors). Store (file).

According to this, image data is meaningless and redundant in units of text data storage and reading, such as sectors. The document writing (document file) area is now extremely narrow, which shortens the access time and requires less storage capacity. When reading a document, image data is read from the writing area outside the document file by decoding the writing area data in the document file, and the storage area information of the image data in the text data and vector data is read out. is inserted at the location where it exists,
This reproduces the original document information.

Even if the image data is stored in a separate area from the document file in this way, the overall required storage capacity will not change, but the number of information bits of the image data will increase from 1 bit to 1 page, for example. It has the widest range, up to the number of bits per page (or a fraction of a page if it is limited to a fraction of that), and the maximum number of bits required is enormous.

In contrast, the number of text 1~data is extremely limited, from the code indicating one character to the maximum number of characters for one page, and even the maximum number is extremely small compared to the number of image data bits. , and since the number of vector data is extremely small, by storing and processing image data separately from text data etc. as described above, the storage area (document file area) allocated for writing a document can be allocated for one document in advance. It is possible to set a relatively small range for each file, and it is possible to file a large number of documents. Since only image data is written in a separate area, even if the area becomes full with writing, other documents (files) without image data can be stored.

As described above, according to the present invention, within the limited storage capacity,
Many documents can be written (files).

In this way, since redundant data (image data) is removed from the document file, document access and data access for each sector within each document becomes extremely fast, and the operator has less waiting time. Increased work efficiency.

In addition, image data has no meaning in processing in storage divisions such as sectors, from text 1 to data, and this is a cause of slowing down the processing speed. Since the data is processed in the image data, it has the advantage that the image data can be accessed quickly. Therefore, according to the present invention, the processing speed can be extremely fast, and the number of documents that can be filed (stored) can be extremely increased, both when and without image data.

In a preferred embodiment of the present invention, the apparatus further includes a data compression/reproduction means for compressing and storing the image data, and for reading and reproducing the stored image data. According to this, the storage capacity of the image data can be reduced, and the number of document files containing the image data can be increased accordingly.

Image data, like text data, takes a very long time to access, even though sector division, for example, has little meaning as information division. Therefore, in a preferred embodiment of the present invention, even when transferring document information, image data is transferred in units (eg, tracks) that are larger than storage units (eg, sectors) of text data.

In this embodiment, the image synthesizing device SPI further includes a mouse 1173 and a communication control device 120 in addition to normal word processor functional elements, and can process document data (including text, vectors, and images) in document units (within a predetermined number of sheets). can be recorded on a floppy disk, and can also send and receive data to and from other stations. Furthermore, mouse 1
At step 173, a part of the display document surface can be specified and the image information received from the workstation wS can be combined.

Further, like a normal word processor, a printer can be connected, and by connecting the printer to the input/output port 117, printing can be performed at that location.

A compound document processing network system consisting of stations that share such functions is configured to work most efficiently in order to process compound documents containing text (words), vectors, and images. There is. In this way, the data handled within the system are mainly text, graphics, and images, and each of these may be used alone or in a complex combination.

Regarding text I-, it is possible to handle multi-fonts (character shapes) and multi-point 1- (character dimensions) regardless of whether it is Japanese or European. When these data are handled within the network and stored in memory, they are binary information in the form of codes, vectors, or pixels (images), and pixel information is is the compressed form or the original read information.

Data can be input into the system from the keyboard 1172, digitizer, or scanner 1171 of the workstation S, from the outside as a facsimile signal via a communication line, and from the host computer by code. There is.

When a completed document is transferred to another workstation, sent via facsimile, or reproduced by print station PS, it is input and processed as pixel (image) information from scanner 1171. In this case, the sending workstation handles all the information in pixels, compresses the data, and sends it over the network. If the recipient of the transmission is a workstation, it will be treated as an e-mail, and if the workstation is at work, a part of the screen of the display device 1161 will display that the mail has arrived to notify the operator. . The operator can recall the document to the screen at an appropriate time. In this case, since the information is in pixels, the data is restored from its compressed format, subjected to linear density conversion to pixels for screen display, and then sent to the display 1161. Note that since the original compressed information remains in the memory as it is, whether to save or delete it is determined by the operator's instructions. Next, if the sending party is a facsimile machine, the signal within the island network will be sent to FC5.
sent to. In this case as well, since it is pixel information,
After decompressing the data and performing linear density conversion for facsimile, it is sent.

In addition, if the destination is a print station, in principle, if the print station is not printing, it will be printed immediately, and if there is a pause during printing, it will be temporarily stored in memory and then printed after waiting for its turn. Ru. The print station has three priority levels. The first is a local copy that is read from the printer 1-station scanner 1232. In this case, even if Printer 1-station is doing other work, that work is interrupted page by page, and the local copy is read from the printer 1-station scanner 1232. The mode changes and local copy is executed. The second type is a job with an "urgent" tag added, and the third type is a "normal" job.

That is, there are two types of work requests from within the network: ``urgent'' and ``ordinary.'' A job tagged with ``urgent'' is executed with priority as soon as the currently executing job is completed. "Normal" work is processed in the order in which requests arrive. "
The distinction between ``urgent'' and ``ordinary'' can now be made operational with the rate's programmable billing processing function9.Next, the first way to use the scanner is to scan personal images (imprints, signature letters, personal characters, etc.). The second is the input of large amounts of documents. In this case, pixel information input from the scanner 1171 of the workstation vS is sent to the OCR station 0CR5, where it is converted into a code and sent back.

In addition, when creating a document containing a mixture of text, graphs (illustrations), and pictures on workstation v5, enter text from the keyboard 1172, illustrations from the digitizer, and pictures from the scanner 1171. Compose them using a composite editor. In this case, by running an image processing program in the composite editor, it is possible to freely edit the image, such as moving the position, enlarging it, and reducing it. In order to assist this work, the image on the display 1161 is capable of multi-window processing. In other words, the image on the screen can be either a completely divided image or an image made by stacking multiple sheets of paper shifted from each other. The image remains the same, but some parts become invisible. In addition, the system status and currently available commands are also displayed in the system area on the display.

When the compound document created in this manner is stored in memory, it is stored in the form of codes, solids, and compressed pixels. Also, if you send this compound document to another workstation, FC5, or print station in the same way as the image information described above, the other workstations will not receive the sent code, vector, or compressed pixel information. and display these information on display 1.
161, a pit stream is developed on a pit map memory by using a character generator (CG) for codes, a graphics generator (GG) for vectors, and expanding pixels. Display this pit stream information 1161
If the data is transferred by DMA to the video RAM 116 of the sender, exactly the same information as that of the sender's workstation will be displayed on the display 1161 of the receiver's workstation. In the same way, the print station and file station also store pins on the bitmap memory.
- Expand the stream, and the subsequent processing is the same procedure as for the pixel information described above, to print or store it in a file.

The ROM 11113 stores programs for the CPU 1140. Interrupt multiplexer 1154, like processor 111,
When an interrupt is received from the local bus 1161, it is accepted and assigned to each level.

Note that the timer, interrupt circuit, etc. are built into the CPU 1140.

FIG. 6 is an internal configuration diagram of the multipath memory 113 in FIG. 3.

Since the RAM (256 KB or 512 B) 1180 has a word unit configuration, when data is input in byte units, the memory controller 1-roller 1166 identifies whether it is upper or lower and switches it. During input/output to the RAM 1180, the error detector 1167 checks the input/output data.

The multipath 1110 includes an address buffer 1175, a control buffer 1176, and a data buffer 117.

Since it is already sent in the form of a picture mixed document bitmap, it performs the function of displaying the contents of the video RAM 1200 of the refresh memory on the screen as is. Therefore, the graphics controller 1199 also has a built-in refresh counter and only controls the controller 1-roller 1201 and address launch 1202, and the DrtAM controller 1-roller 120■ has a built-in refresh counter. 200 is periodically refreshed.Data 1 transceiver 1204 is
When transferring bitmap data in the opposite direction, control such as reversing the input/output direction is performed.

FIG. 9 is an internal (configuration) diagram of the parallel 10117 in FIG. 3.

Since this parallel i10117 board is versatile, it can have a parallel data interface function no matter what is connected to the connectors Jl-J4. In this embodiment, a scanner 1171, a keyboard 1172 .
A mouse 1173 is connected. The I(l processor 1210 of the parallel I10117 executes the program stored in the ROM 1224 according to instructions from the processor 111, and performs input/output operations of 8-bit parallel and 16-bit parallel data.

For example, when input data from the keyboard 1172 is stored in the memory 114, data input from the controller 1 to the roll transceiver 1221, address 1 to transceiver 1222, data transceiver 1223 to private 1 to bus 117 is stored.

Read the data and use a floppy disk as a backup in the event of a failure.

Figures 11, 12 and 13 are respectively directed to the image processing unit 1 in Figure 3 (IPUI, 2.3).
1151, 1152, and 1153 are internal configuration diagrams.

The IPU 1151 performs compression/expansion processing of image processing, the IPU' 1152 performs density conversion, enlargement and reduction processing, and the IPLI 1153 performs rotation processing.

That is, in order to send the data to a communication line or to transfer it to the file station FC and store it, it is necessary to compress the data to save transmission time and storage capacity. or C
In order to display on the RT display 1161, the compressed data must be decompressed back to the original image (pixel) information.

In the IPU 1151, the address signal, control signal, and data are sent from the local bus 1111 to the address transceiver 1263 and control 1 to rungeever 12, respectively.
64, and received by data 1 to transceiver 1265.

The input data buffer 125G is accessed by the address selection circuit 1262 and data is temporarily stored there.

The status register 1261 identifies compression or expansion, and the controller I-roller 1260 controls the compression/expansion unit 125.
When inputting to 3, parallel to serial converter 1258
Convert it into serial data and input it to the compressor/expander 125.
When outputting from 3, serial-parallel converter 12
At step 59, the data is returned to parallel data, temporarily stored in buffer 1257, and sent to local bus 1111.

Next, as the need for density conversion, for example, the scanner 117
The image input from 1 has a line density of 12 lines/mm,
When displaying on CRT display 1161, 4/
mm may be used as is, but in some cases, only the photograph may be enlarged or reduced for display.Also, if it is transferred to print station PS for printing, it may be transferred to communication station DC5, FC5 for communication transmission. In this case, it is necessary to convert to an image of 8 lines 1III+. In addition, the processor tit processes and the memory 113
When storing data in , it may be converted to 12 lines/mn+.

Next, regarding the need for image rotation, document data input on A3 size paper with horizontal writing is transferred to the CRT display 1161.
This may be the case if you want to display the data in m-letter format, or if you want to print document data input on A4 size paper in vertical writing on printer 1-station PS.

IPU1152 for density conversion. IPU1153 for rotation
The same control is applied to the smell as well, using the same route except for the conversion processing circuits 1254 and 1255.

Figure 14 is the communication control bag in Figure 3! (CCU)
1.20 is an internal configuration diagram.

CCIJ 120 relays data from local network cable 19 to local bus 1111 within the station, and from local bus 1111 to cable 19. In that case, the station communicates with other stations according to the protocols necessary for exchanging data on the local network. The IESI (interface) 1267 transmits and receives reception signals (RD), transmission signals (TX), and carrier detectors (CD). It constantly monitors whether or not data is flowing through the cable 19 by detecting the carrier detector (CD), and when there is no data, it sends out a transmission signal (rx), but it detects that the data is different from the one it sent. A collision is detected by detecting this, and retransmission is performed at a different timing. In that case, by providing a random time, transmission is performed after the random time has elapsed after the collision. others,
It is determined whether the data flowing through the cable 19 is addressed to the own station or to another station. Local bus 1111 has bus arbiter 1269. Bus controller 1270. Control signal 1274. Address latch 1271.

A maximum of 1500 bytes of packet data is temporarily stored in the internal buffer.

Referring again to FIG. Although the capacity value of the document processing device PL may differ, it is roughly equivalent to the workstation V.
It has the same configuration as S. However, in this example, scanner 1171. The mouse 1173 is omitted. Functions include image reading (scanner reading) and its processing,
Essay 1 editing, record 1 communication (document data transmission and reception)
, printout, and communication with the outside via DO3 or Fe2 (facsimile communication and data communication) are possible.

In this example, the image synthesis device spi is the text processing device I!
The hard memory 1191 is omitted from lP1, and the mouse 11
73 is added, and it has the same functions as the document processing device storage 1, and the function of image composition of text 1-, vectors, and images. However, the image cannot be read,
Images registered in the workstation S are called up and synthesized. Furthermore, since the hard memory 1191 is omitted, if text data that exceeds the floppy surface is input, an error occurs when the data exceeds the floppy surface, and data acceptance is then stopped. Communication within the system or outside the system is limited to data within one floppy disk.

Other text processing bags [WF2, 3. ... also has a similar configuration to INPI, but the hard disk 1191 may be omitted. When the hard disk is omitted, the device operation program, dictionary, and other functional data are stored on a floppy disk, and the floppy disk is loaded after reading the floppy data into the memo 14 or 115.

Other image synthesis devices SP2, 3. ... also has a similar configuration to SPI, but the composition function may be omitted.

These image synthesis devices SPI, 2, 3. ... is 1 sentence processing device [Pl, 2, 3. The text created and sent by ... is displayed on the display screen, and the operator specifies a predetermined location on the text surface using the mouse 1173, and displays images such as images, vectors, etc. on the workstation ttS using the board 1172. Instructing data transfer, the device SPI, 2, 3 . ... to compose the image at the position specified by the mouse, and when the operator instructs execution, to send the composite image data back to the source of the text data, and to have the printer station PS print 1 to au 1 instead. Since its primary purpose is the function of selecting and instructing both, the text creation function may be omitted and the text processing device may be used in parallel. However, if the operator composes the image using the same machine after the operator composes and edits the composition, the composition 2 editing function is not omitted.

In the document 2 image processing system described above, the present invention is mainly related to the workstation vS,
This is a file of an edited document using WPI, Sl'1, etc.

Next, work stage 32159 document processing device vP1.
2, 3. . . . and image synthesis device SPI, 2, 3.・
The data structure of the document processed by ... will be explained. In addition,
The workstation WS is capable of inputting/outputting text, flats, and images, editing them (that is, creating documents), and storing (storing and registering) them. Document processing device WPI, 2, 3. ... cannot input vectors or images. However, it is possible to edit vectors and images registered on the hard disk of the workstation ttS or other devices by recalling them and combining them with text. Image synthesis device SPI, 2, 3.・
... cannot input images. However, it is possible to recall images registered on the hard disk of the workstation VS or other devices and edit them by combining them with text and vectors. In this way, not all stations can use images, vectors, etc., but even those that cannot.

You can edit documents using images and vectors stored on your hard disk.

Therefore, the mechanical format of the document is commonly defined for all stations as shown in Table 1 below.

Table 1 Document The structure of the document header of the document (Table 1) is as shown in Table 2 below.

The structure of the document data of the Table 2 document (Table 1) is as shown in Table 3 below.

Table 3 Document 1 - Data The data structure of each page of document data is as shown in Table 4 below.

The structure of the document data page header (Table 4) on the first page of Table 4 is as shown in Table 5 below.

Table 5 The structure of the page data (Table 4) is shown in FIG. 6 below.

is input by the scanner 1171. The data thus entered can be sent to the workstation with a password attached thereto, where it can be registered in the hard disk 1192 (FIG. 3). Furthermore, any station whose keyboard is equipped with a data transfer key can receive registered data. Therefore, at a station with an editing function, it is possible to receive registered data by transfer and edit a document that combines illustrations and images with text, without having to be equipped with a mouse or a scanner.

The CPU 111 of each station inputs/outputs and edits text, illustrations, images, etc. When editing, the page data storage area (data bunten memory) and page pixel data storage area (data storage area) in RAM (document memory) are used.
pixel document memory), the input/output data is first stored in the data document memory, and then the text data in the data document memory is transferred to phono 1 to character pattern memo 1.
The vector data is converted into a bit image representing the line it represents and written into pixel document memory. That is, a bitmap is created in pixel document memory. When transmitting and receiving (transferring) information within the system shown in FIG. 1, data is transferred to and from the data document memory (image data is compressed by the other party) in accordance with instructions from the other party's station.

Compressed data is sent if it is reproducible, and uncompressed data if it is not reproducible.However, when it is sent and received outside the system in facsimile mode, it is sent in the form of data in the pixel document memory.

FIG. 15 shows an outline of the main parts of the operational flow of the workstation tis, the document processing device WPI, the image synthesis device SP1, etc. This flow will now be explained for workstation vS as follows. That is, in response to a function key input on the keyboard 1172, text editing, vector editing, image editing, 1 correspondence transfer, 2 document printing, 2 document file (storage).

Image registration, document reading, etc. are executed based on the application program specified by key-in.

In text editing, a normal word processor's text creation 1 editing is performed, text data corresponding to input key operations is stored in the data document memory, and among them, character pattern bits represented by character codes are The arrangement specified by the instruction code is written to the pixel document memory and displayed on the display.

In vector editing, the mouse position is displayed on the display, line drawing data (solid 1 hell) is stored in the data document memory according to the function key settings and the operation of the instruction keys on the mouse, and the vector] - A bit image actually representing the file is written to the pixel intersection memory and displayed on the display. This flat-screen editing is similar to reading illustration 1 in image registration, which will be explained in more detail later. First, the mouse input is read, data is loaded into the data document memory and pixel document memory, and the data is displayed.
Thereafter, data of the illustration within the rectangular area specified by the mouse is left in the pixel document memory in accordance with the operation of the function keys. The entire data document remains in memory. After that, first write the document data to the data document memory and pixel document memory, and if there is a document that was saved during image processing, turn on the execution key to write the side other than the rectangular side of the remaining illustration first. Create document data filled with the document information in the data document memory and pixel text memory, and leave the information in these memories as they are.
Finish editing Bec I.

As mentioned above, illustration editing involves reading the illustration with a mouse (reading editing) and using the hard disk 11.
There is also a method for calling and using illustrations registered in 92 (call editing). The latter is similar to the image editing shown in FIG. 17 (described later).

In image editing, the scanner is moved in response to function key operations to read bit images of one page of images, write them to a buffer and pixel document memory, and display them on the display.

This image editing is similar to reading the image in image registration, which will be explained in more detail later, and then stores the image data within the rectangular area specified by the mouse in the pixel document memory according to the function key operation. . After that, write the document data to the data document memory and pixel document memory first, and if there is a document that was saved during image processing, turn on the execution key to write the side other than the rectangular side of the remaining image first. Document data filled with document information is created in a data document memory and a pixel document memory, and the image editing is completed while leaving the information in these memories as they are. In addition.

As mentioned above, there are two types of image editing: one is to read an image with a scanner (read editing), and the other is to call up and use an image registered on the hard disk 1192 (call & (north). The latter is the 17th This will be described later with reference to the drawings.

In document transfer, an edited document is transferred, and in intra-system transfer, a document is transferred after being processed according to the functions of the other party. The basis of transfer within the system is the data format of the data document memory. If the destination is equipped with a compression and playback device, image data is transferred as compressed data, but if it is not, it is transferred as a bit image. . When sending and receiving data outside the system via a facsimile station, the data is in the pixel document memory data format. Transmission/reception to/from outside the system without going through a facsimile station uses the same data format as for transmission/reception within the system.

When printing a document, the document is sent to the print station by intra-system transfer, and then the print process is executed there.

The document file is a storage (file) of an edited (including newly created) document in the hard disk 1192 (document file). Details of this will be described later with reference to FIG.

Image registration is the process of registering relatively important images (images and solid colors) on the hard disk 1192. At this point, image processing similar to that of solid 1 to color editing and image editing is performed. Details of this will be described later with reference to FIG. 16a.

In document reading, a document stored in the hard disk 1191 is read into a buffer. The details will be described later with reference to FIG. 19.

Next, registration of images (vectors and images) will be explained with reference to FIG. 16a.

When proceeding to image registration, the processor 111 reads an image registration program from the hard disk 1191, stores it in the RAM, proceeds to its execution, and displays an image registration processing menu on the CRT display screen. This is step 1 in Figure 16a. Check the image registration again here. This is step 2. In the first run of this run, the CRT
The display 1161 displays the message "Please use the numeric keypad four times to enter the password (cipher)" (
Step 6).

Then, wait for the numeric keypad input and read the numeric keypad input four times (step 7), and this time the message ``Press the ``Image'' key for image input, or the ``Illustration'' key for illustration input'' will be displayed. (Step 8).

Now wait for these key powers and in step 9 select "Image"
When it is detected that the key has been pressed, a message saying "Please insert the original into the scanner and press the start key" is displayed. When it is detected in step 15 that the "Illustration" key has been pressed, the message "Please use the mouse to draw an image on the CRT. When finished, please press the end key" is displayed (step 16).

When the operator sees the message ``Please place the original in the scanner and press the star 1-key.''

Place the image paper to be registered on the contact glass plate of the scanner 1171, and press the star 1 key.

When the message "Use the mouse to draw an image on CITT. When finished, press the end key." is displayed, the operator operates the mouse 1173 and keys on the keyboard 1172 to CR the desired illustration.
Draw on the display surface of the T-display.

The processor 111, when the scanner starts from star 1 to step 11), stores the received image information in the RAM, gives it to the processor 112 for each predetermined block to display it, and receives the end of one page from the scanner. ``Place the cursor in the upper left position of the frame to be extracted and press the mouse switch'' is displayed in the margin of the display surface of the CRT display (step 14). In addition, when "1 image creation" is input, the processor 111 stores bright spot data at the address indicated by the position data in the RAM memory allocated to the 1 page memory every time the position data from the mouse changes. Step 17) When the end key is turned on, the process advances to step 14.

After displaying in step 14, the process proceeds to the flow shown in FIG. 16b and waits for the mouse switch to be turned on (step 19). When the mouse switch is turned on, the cursor address at that time is stored in memory (step 20). It should be noted that the explanation will be repeated later, but the mouse is used to indicate the position of the display cursor on the CRT display, and the cursor moves in conjunction with the movement of the mouse.

Next, in step 21, the processor 111 displays the message "Please place the cursor at the lower right position of the frame to be extracted and press the mouse switch" and waits for the mouse switch to be turned on (step 22).

When the mouse switch is turned on, the processor 111
Leave only the image data inside the rectangle whose diagonal points are the two cursor addresses that have been input so far, and save the rest.
If you are satisfied with the registration, turn on the execution key, and if you want to try again, press the mouse switch.'' is displayed (step 25).
). Then wait for the execution key or mouse switch to be turned on (
Step 26.28). When the execution key is turned on, in the case of an image, the data of the displayed image (inside the frame) is compressed by the compression circuit 115.
1, and the hard disk 119 with a password.
1, step 27), and return to step 1. In the case of an illustration, it is saved to the hard disk with a password without being compressed, and the process returns to step 1. When the mouse switch is turned on, step 29) returns the CR1' display to the one-page image, and the process proceeds to step 14.

Although explanations and illustrations have been omitted, there is a display that says "If you wish to exit, please press the return key" at a required step, and if the return key is turned on while this display is displayed, the processor 111 will restore the previous input. Clear all and return to step 1.

As described above, images and illustrations are registered using the scanner 1171 or the mouse.

Next, referring to FIG. 17, the image registered in the hard disk 1192 (FIG. 3) as described above.

The operation of editing illustration I-) into a document will be explained.

First, the premise will be explained. For example, if you create and edit a document using text editing and then instruct image editing, a menu will be displayed in a different location from that of the document.

This is step 30 in FIG. When image compositing is instructed in this state, the message "Please place the cursor at the upper left of the writing area and press the mouse switch" is displayed on the CITT display (steps 31 and 34). In this state, the text can be scrolled using the keyboard and the required part of the text can be displayed, so the operator can check the text and, if necessary and has the ability, use the keyboard to scroll the text. Correct it, display the writing position on the screen, and move the cursor to the upper left of the writing area. In response to the subsequent switch-on, the process proceeds to step 3G where the message "Please enter password" is displayed (step 36). After reading the numeric keystrokes four times, the numeric keypad manual code (password) is sent to the workstation 115 to request image transfer (step 38). The workstation WS sends an image (and then stores it in RAM, and displays the composite image on the CRT at the cursor specified position of the text while keeping it stored separately from the text data and image data). Step 39). Then, display in the margin of the screen, ``If you agree, please press the execution key, otherwise press the cancel key'' (step 40)
.

Then wait for the key to turn on. When the execution key is turned on, B sets of document data in which images are combined with sentences are updated and stored in the RAM as displayed. Then, the process returns to the menu display in step 30 (step 4L42).

When the cancel key is turned on, the CIIT display is returned to displaying text only, and the process returns to step 34 (step 43).
．． 44).

Next, the document file (storage) will be explained with reference to FIG. As described above, the document memory includes a data document memory and a pixel document memory, and the data in the pixel document memory is given to a CRT display device to display a document, but the contents of the data document memory are shown in Table 1. The structure is shown below, and in the document: file,
The data in this data document memory is transferred to the hard disk 119.

In the document file (storage), first, the document header (Table 2) in the data document memory and the document 1
~・Image part of data (Table 6 and Table 1I)
i.e. document 1-header (second
Table), page header of page division (Table 5).

The text 1- (Table 7) and vector]-le (Table 9) are stored in the system buffer memory (each station νS, lNl1

). Next, the system management disk (hard disk 1191 in this example) is installed in the disk controller 1 to roller.
) and transfers the contents of the system buffer memory to the human output buffer (engine 10 buffer) of the disk controller 1 roller. System management disk (1191) for workstation l1lS and document processing bag MvP1
However, since the image composition device Sr'l does not have a hard disk 1191, the document data is stored in the workstation or document processing device Wl'.
The data will be transferred to L and written to the hard disk there.

The same applies to the following write processing.

Next, the disk controller 1-roller writes the data in the I10 buffer to the system management disk 1191 in units of sectors.

Next, the entire file of the data document memory is written to the system buffer memory in the same way, the disk controller is instructed to write to the system management disk 1191, and the I
The data in the system buffer memory is transferred to the 10 buffer and written in sector units to the system management disk 1191.

Next, it compresses the image in the data document memory, sends it to the playback device, instructs compression, stores the compressed data in the I10 buffer of the system-unmanaged disk (hard disk 1192), and instructs the disk controller to write it. Compressed data is written track by track on a disk not managed by the system, and management information for the compressed data, that is, information specifying the compressed data, is written in the system managed disk 1191.

Through the above steps, the document data has been filed (stored).

Next, document reading will be explained with reference to FIG.

This document reading is for reading document data stored in the aforementioned document file.

First, instruct the disk controller to read the image of the specified document, read the image data to the I10 buffer, then compress the data in the I10 buffer, give it to the playback device to instruct playback, and write the playback data to the data document memory. .

Next, instruct the disk controller 1-○- to read the text and read the data (document) to the I10 controller.

Transfer 10 buffers of data to the system buffer.

Then, the data in the system buffer is written to the data memory. Similarly, flats 1 to 1 are read out and written into the data document memory.

Next, the text 1- in the data document memory is converted into a pattern image, the vector is converted into a line-r image, the pip 1-image is developed in the pixel document memory, and Cr1T
Display the first page on the display.

In the embodiment described above, the hard disk 1191 is used for document files, and images are stored in the hard disk 1192, but the document file area and other storage such as images are stored on the same hard disk. The area may be divided into separate areas and used separately for storing document files and image memory.

■Effect As described above, according to the present invention, text (sentence).

Of the document data edited from vectors (illustrations) and images (pictures, photographs), text 1- and vectors that have a small number of data bits and a narrow data amount range are stored in sectors, etc. in document files such as system management disks. Write (memorize) to the text 1 in small units suitable for data processing, and write (store) images to the data pin 1 in a separate area from the document file, such as on a disk not managed by the system. Since data is written to the storage area in units such as tracks that are larger than text data processing units, document data can be accessed very quickly, and the throughput of the information processing apparatus is significantly increased.

Also, the storage of many documents can be pre-allocated in the document file.
