Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compound document processing network system, and in particular to a local area network system for creating, storing, searching, and communicating documents containing a mixture of numerical tables, text, graphs, images, etc.
It is related to network systems.

In the past, most local document processing network systems handled only character and graphic code information. In recent years, as the needs for office automation have increased, the creation of documents with images has been developed, but this has not yet reached the point where a four-cal network system can be configured. Another problem when handling images is that images with different image line densities cannot be handled in a unified manner. For example, conventionally, inch-based data terminals handle images with a linear density of ÷5 lines/double or 9.4 lines/-, and
The 7-ont dot character has 4 lines/character size of 6 x 6 m.
It is displayed on the screen of a display device with a linear density of m. If these 7 onts are directly output to a printer with a line density of 8 lines/■ and printed, the characters will be small (3 x 3 letters), so linear density conversion will be necessary. The quality of the characters deteriorates, such as the constituent elements disappearing.

In addition, high-speed data communication uses protocols such as HDLC, and image communication uses data compression for high-speed transmission, but data terminals with different data compression methods and protocols can be used within one local area network. If they are set up, communication will not be possible between them.

In addition, conventional printers have been equipped with multiple 7-onts for English text, but for Japanese text, Gothic fonts have a fixed size, so both font and size are different. On the other hand, there is no one that can handle various fonts.

You can also print within your local area network.
If a station is provided, it only prints the output of the processing device or prints documents received via the network, and cannot be used as a copying machine.

Additionally, traditional local area networks
Since the facsimile machine and the like do not have such attribute conversion, it is impossible to transfer data from the facsimile machine H'4 to the mail box of the print station or between the file station and the facsimile machine.

The purpose of the present invention is to improve these conventional drawbacks by
Creating documents that are located in the same building or within a restricted area;
Integrated processing of copy printing, storage retrieval, and transmission enables efficient equipment utilization and improves overall system efficiency.
(2) Easily expand and change the system to enable system construction according to scale; and (3) Documents containing a mixture of text, numerical tables, graphs, and images. By seriously handling
Our objective is to provide a complex civil-office processing network system that can meet the hot needs of office automation.

The greeting document processing network system of the present invention is equipped with the following functions.

(1) Document creation machine F7R: At the work station, you can create and edit various types of documents. It has functions such as image input and editing, creation and processing of forms, graphs, illustrations, and numerical tables, composite editing of these, page layout, and document formatting.

A compound document processing network system consisting of stations that share such functions is configured to work most efficiently for processing compound documents containing text (word), graphics, and images. In this way, the data handled within the system are mainly text, graphics, and images, and these may be used alone or in combination. Regarding text, it is possible to handle multi-fonts (character types) and multi-points (character dimensions), regardless of whether it is Japanese or European. Then, when these data are handled within the network and stored in memory, the V
]tJ is binary information in the form of a code, vector, or pixel (image), where the pixel information is in compressed form.

Data can be input into the system from the keyboard 1172, digitizer, or scanner 1171 of the work station 11, from the outside via a communication line as a facsimile signal, or by code input from the host computer 6. There are cases where it is done.

When a completed document is transferred to another work station 11, sent via facsimile, or printed at print station 12, it is processed as pixel (image) information from scanner 1171. I will do it. In this case, the transmitting work station 11 handles all information in pixels, compresses the data, and sends it to the network. If the recipient of the transmission is the work station 11, it will be treated as an e-mail, and if the work station 11 is at work,
The fact that the mail has arrived is displayed on a part of the screen of the display device 1161 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 and subjected to linear density conversion to pixels for screen display before being sent to the display 1161.

Note that since the original compressed information remains as it is in the memory, it is determined whether to save or delete it based on the operator's instructions.

Next, if the destination party is a facsimile machine, the signal within the island network or network is sent to the FCS 17. In this case as well, since it is pixel information, it is transmitted after decompressing the data and performing linear density conversion for facsimile.

In addition, if the destination is the print station 12, in principle, if the print station 12 is not printing, it will be printed immediately, and if it is printing, it will be temporarily stored in memory and then printed after waiting for its turn. be done. Print·
Station 12 has three priority levels. The first is the scanner 123 of the print station 12.
In this case, even if print station 12 is doing other work, that work is interrupted page by page and the local copy mode is changed to local copy mode. The copy is executed.

The second is the work with the tag "Ship", and the third is "
It's a normal-1 job.

In other words, there are two types of work requests from within the network: ``Urgent'' and 1-Normal, and jobs with the ``Urgent'' tag will be prioritized and processed as soon as the currently executing job is completed. Ru. "Normal" work is processed in the order in which requests arrive.

The distinction between ``full session'' and ``1 regular session'' can be operated using a rate programmable billing processing function.

Another way to use a scanner is to input a large amount of documents. In this case, scanner 1 of work station 11
Pixel information input from 171 is sent to OCR station 15, where it is converted into a code and sent back.

Furthermore, when creating a document containing a mixture of text, graphs (illustrations), and pictures at the work station 11,
Characters are input from the keyboard 1172, illustrations are input from the digitizer, and pictures are input from the scanner 1171, and the combination editor of the work station 11 is used to synthesize them. In that case, by running an image processing program in the composite editor, it is possible to freely edit the image, such as moving, enlarging, and reducing the position. To assist this work, the screen of the display 1101 is capable of multi-window processing. In other words, the image on the screen can be either a completely divided image or an image of several pieces of paper stacked one on top of the other, shifted from each other.
In the former, each image is reduced in size, whereas in the latter, the size of the image does not change and some parts become invisible. the(
[lJ, System status and currently available commands are also displayed in the system area on the display.

When a compound document created in this manner is stored in memory, it is stored in the form of codes, vectors, and compressed pixels. In addition, this compound document can be sent to other workstations 11, FC 81 in the same way as the image information mentioned above.
7. When sending out to the print station 12, the other work stations 11 receive chords, vectors, and compressed pixel information that cannot be sent. In order to
The code is created using a character generator (CG).
Bitmaps are created by using vectors with a graphics generator (GG) and by stretching pixels.
Expand the bit stream in memory. This bit stream information is sent to the video camera I1 of the display 1161.
．． A, M l l (After the DMA transfer to 3, the display 116 of the work station 11 on the receiving side displays exactly the same information as on the work station 11 on the sending side 1.
1 will be displayed on top. In the same way, the print station 12 and file station [3] also expand the bit stream on the bit map memory, and thereafter perform printing or file storage using the same procedure as for the pixel information described above.

It is.

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

That is, in order to transmit the data to the communication line or to transfer it to the file station 13 and store it, the data must be transferred to F'F,l? On the other hand, it is necessary to decompress the compressed data in order to process it in the processor 112 or display it on the CR,T display 1161. It is necessary to restore the original image (pixel) information.

In the IPU 1151, address signals, control signals, and data are transmitted from the four-cal bus 1111 to an address transceiver 1263 and a control transceiver 1264, respectively.
, and is received by the data transceiver 1265 and input to the input data buffer 125 by the address selection circuit 1262.

A controller 1260 controls a compressor/expander 1253 to perform processing. When inputting to the compression/expansion unit 1253, the parallel/serial converter 1258 converts the data into serial data, and when outputting from the compression/expansion unit 1253, the serial/parallel converter 1259 converts the data into parallel data.
The data is returned to data, temporarily stored in buffer 1257, and sent to local bus 1111.

Next, as the need for density conversion, for example, the scanner 117

When displayed on the RT display 1161, it is sufficient to keep the number of 4 lines/simplified, but in some cases, only the photograph may be enlarged or reduced in size, and when transferred to the print station 12 for printing, the communication station 16 , 17 for communication transmission, it is necessary to convert the image into 8 images/simplified image. Furthermore, when processing the data in the processor 111 and storing it in the memory 113, 12 main files may be converted.

In that case, the station communicates with other stations according to the protocols necessary for exchanging data on the local network. The ESI (interface) 1267 has a reception signal (RD), a transmission signal (TX), a carrier detector (
Send and receive CDs. Whether or not data is flowing through the +- pull 19 is constantly monitored by detecting the carrier detector (CD), and when there is no data, the transmission signal (TX
), but detects a collision by detecting data different from what it sent, and retransmits it at a different timing. By providing a random time for both 1 and 1, transmission is performed after a random time has elapsed after the collision. The station 1 identifies whether the data flowing through the cable 19 is addressed to its own station or to another station. local bus 1
A bus arbiter 1269, a bus controller 1270, a control signal 1274, an address latch 1271, an address transformer 1273, and a data transformer 1272 are connected to the LANC (
Parallel data is input to the controller (controller) 1268, but serial data is output to the cable 19. A maximum of 1500 bytes of packet data is temporarily stored in the buffer in the L A N C,12eJ8.

FIG. 18 is a software configuration diagram of the work station 11 showing an embodiment of the present invention.

The work station 11 includes an operating system (O3) 1290 and processors (system software') 1291 to 12 that assist the functions of O8.
99, application processors (user applications') 1300 and 1301, and drivers 1280 to 1288 that drive each device within the station.

The work station 11 has terminal functions that can be used by general users within the system.

These terminal features include: (1) Ability to create print-like documents using Multi-7 Ont, (11
) Ability to create printed documents that include a mixture of text, graphs, and images, 011) Store and search shared files,
Ability to use e-mail, (iv) Ability to execute commercially available programs, (v) Ability to create and execute user programs, υD electronic signature (signature), ability to execute a seal system, &1 [Confidentiality system (Function to create V+iD form, function to process asthma number table,
Ho) Business graph processing function, Ho1cAD (Com
putter aided l)eeign) function.

Next, the main programs will be explained.

(a) Operating system (OS) O8 is (1
) where real-time processing is emphasized (OS kernel) and (1)
1) It is roughly divided into other processing parts (OS executive parts). Part (1) includes processing unit fQ Qll allocation, hardware interrupt control, memory space management, etc., and part Oi) includes input/output processing, inter-task communication, task execution control, software interrupts, etc. / indexing, address space management, protection functions, etc.

Next, the main operation of i- to O8 will be described.

(1) Process management: A process is the basic unit for scheduling execution in a system.
It is assigned to each processor shown in FIG. 8 and executed. Processes are divided into system processes and user processes based on their execution functions.

And 1. Processes with priorities are executed according to their priorities, and processes with the same priority are executed according to a round robin schedule. In addition, every process has a quantum set to determine the minimum processing time, and when that time is consumed, the state is switched.

FIG. 19 is an explanatory diagram showing process states and swapping.

Processes can be active (ACTIVE), waiting for processing (READY), waiting for event completion (WA■T), or stopped (SUSPEND) due to events.Events that change the state of the process (system events) include events.・There are flags, input/output, time passage, etc. As shown in Figure 19,
A process waiting to be processed is loaded onto real memory by swapping from auxiliary memory. The process to be loaded is selected from those with higher priority among those waiting to be processed. Furthermore, if an event wait occurs during an activity, the event waits for completion, and is returned to the auxiliary memory in order of priority by swapping.

(11) Communication between processes All communication between processes is performed through system input/output, and when a process with which to communicate specifies a partner and issues a request, it is transmitted to the other party as system input. Common event flags shared among multiple processes are managed by numbers and are used for communication to confirm the setting, occurrence, and completion status of events. Further, the mail box is used for receiving and passing data between processes, and if read/write can be performed arbitrarily between processes, data can be sent and received between one and multiple machines. Also, the same virtual memory is shared between processes; some are dynamically allocated in the global area, while others are statically allocated when a process is created.

011) Input/output processing FIG. 20 is a diagram showing input/output processing of O8.

That is, an input/output control routine 1317 is provided in 081290 for all input/output devices fW1310 connected to the work station 11. 08129
0 sends an input/output control command via the input/output capo 1313 of the input/output device 1310 to be controlled, and also sends the status information of the input/output device 1310 to the input/output data W l
311 to transfer input/output data or input/output area information data. Also, system auxiliary process 1304, application process 1
303 sends an input/output request and requests execution of input/output according to the procedure of the system service call processing routine 1318 in 031290. The above input/output request is at the level of a virtual input/output instruction 1315 in the application process 1303, and is transferred along a dotted line path 1314 to interprocess communication processing 1319.
The command returns to the system auxiliary process 1304, is interpreted as an actual command execution request 1316, and is requested to the input/output control routine 1317.

In this case, each process can receive and receive notifications of execution results.

(b) Virtual Display Input Device Control Processor Control of the display input device from each process can be performed independently of control from other processes.

FIG. 21 is an explanatory diagram of a virtual display input device control processor (program).

Each process 1329 is provided with a corresponding number of virtual display input bags f721325, and these are allocated to one real display input device 1 by the real display input device allocation control 1323.
321 at the same time.

Up to 16 virtual display input devices 1325 can be handled at the same time. The interface with the process is performed by transferring virtual input/output instructions from the input/output control routine in O8. Furthermore, the display section 1321 can interface with the operator only when assigned to the real display input device 1320, and the input section 1322 can interface with the operator only when assigned to the real display input device 1320 and when assigned to the real display input device 1320. It is possible to interface with the operator when performing input operations with Note that the prompt can identify the process to which input data is to be passed.

In the virtual display section 1326 of the virtual display input device 1325,
The display content is a composite of the base screen and the area screen (screen corresponding to the process), and the input data from the real input unit 1322 can be input as is in the virtual input unit 1327.

The functions of the virtual display input device ff1325 include (1) being able to initialize the screen, (11) being able to set area screens, 0ii) being able to set screen attributes that correspond to the attributes of display data for the area screen, ) code data are alphanumeric characters, kana, special characters, and kanji, and work
(V) Code data can display a character pattern after it is generated; Vector commands can display a graph pattern after it has been generated; &+I
Compressed binary data can be displayed after decoding (V++D raw binary data can be displayed as is, 1x) Display data can include code data, vector commands, compressed binary data, and encoded binary data. A reception must be provided in the form. (9) Code data can be entered by entering a specific character string.
It is handled as a vector command (ESC code), and the input for controlling the save display can be both code data and direct instruction signals (signals from a mouse, etc.).

Next, regarding the display of code data, (1) it is possible to specify the display position, (11) it is possible to specify the horizontal and vertical directions, and (iii) it is possible to specify the horizontal and vertical directions. Right alignment shown in Figure (b), Figure 22 (C)
These include center alignment and proportional (changing the size) as shown in the figure below.

Next, regarding the display of vector commands, as basic commands, (1) any display position can be specified, and (It) the display position can be changed by specifying a relative displacement from the current display position. , 0++) The above relative displacement can be specified using either rectangular coordinates or polar coordinates, 1iv) The above display position specification (1) (ii) c

A pie display command (see FIG. 23(a)), an arc display command (see FIG. 23(b)), a circle display command, a spline curve display command, and a knot display command are used.

Regarding the display of binary data, (1) it is possible to fill in the designated area;

(11) The filling pattern can be the entire surface, checkered pattern, grid pattern, diagonal line pattern, etc. 0ff) The displayed contents can be moved. (lv) Nothing can be displayed on the screen after the movement, or the background screen can be restored. (v) If the item exits the display screen as a result of movement, it will not be displayed, but if the item moves in the opposite direction, it can be returned to the display screen without being lost. (The contents displayed on the DVD can be copied to other areas.4
11. The content to be copied can be the data in that area as it is, or it can be data with the background screen erased. (viit) Display screens can be arbitrarily combined.

(b) Network control program In a network system, even if a work station 11 fails, it does not affect the operation of the system. - Stations can now be expanded. Also, the network f
M71A lj is not constrained by specific topologies or internal characteristics of communication, and can monitor, maintain, and change network activity. It also allows for changes in transmission media, changes in signaling, or revisions to protocols within the network.

In the communication procedure, the line is connected by detecting whether or not the work station 11 is connected to the line, and then the link is established since the apparent E link has been established. By connecting arbitrary transports, a connection is established between the transports, and a session is established as long as one communication is continuous between the transports. Therefore, while the connection between transports is established,
gFl crotch/closure of the session can be performed freely.

FIG. 24 is a 4i'j Ii diagram of a print station illustrating an embodiment of the present invention.

Print station 12, which is one of the service stations, not only prints documents transferred from other stations, facsimile machines, etc. and outputs them to designated mail boxes, but also performs local initial copying.

First, when the power is turned on, the processor 121 activates the floppy disk drive 1351, calls O8, and calls a program using O8, thereby operating the system program. Then all programs (

Prepare the remaining area for storage. In this case, the transfer route is HD D 1361→F'DC/HDC126
→Memory 122 →p-cal bus 1334 →IPU12
4 → Local bus 1334 → Memory 122 → Private bus 1335 → P10123 → Printer 1331
It is. Note that while the private bus 1335 is in use, the local bus 1334 is available.

Also, in the print station 12, when the printer 1331, scanner 1332, and sorter 1333 are unused for a certain period of time, the T? Turn off the T source. Even if the controller's power switch is turned off, the controller itself remains in standby mode and power is supplied to the necessary boards, and the entire system is automatically powered on when data arrives from the network.

Next, each board will be explained.

(1) The CPU board (121) has administrative functions for the print station 12, including data management and Il.
Start o. In addition, CRT1341 for displaying management contents
Terminal interface and impact or non-impact printer interface for copying code displayed on the terminal. Additionally, a timer for command or processing timeout, or one
It is equipped with an interwoven processing function for detecting the completion of 10 processes.

(11) The memory board (122, 127) has a line capacity of 3 Mbytes and is divided into a bit map memory 122 and a working memory 127 depending on the purpose. The latter is a 0.5M byte F that stores O81 programs, character generators, etc. and is used for general processing.
Equipped with. This warging memory 127 is connected to the local bus 1334 and is also used for exchanging parameters with Ilo. The former stores data (codes, vectors, pixels) sent from the local network or scanner 1332, and is connected to the p-cal bus 1332.
34 and private bus 1335, and arbitrates access from the two buses (bus management,
decision). Therefore, the scanner 133
2 and to printer 1331 can be directly transferred via private bus 1335, allowing other tasks to be performed in parallel using local bus 1334 even during transfer.

G11) The FDC/HD C board (125) has a built-in I10 processor, and when started from the CPU 121, data, O81 and other programs are transferred to the memory 122.
or from memory 122.

Since the board 125 has a buffer memory,
The DMA1 capability included in the I10 processor allows bit map memory 122 or working memory 1
Data and program no-lock transfers can be performed with 27. floppy disk drive 135
1 and hard disk drive J361 can be expanded to up to four units each. Floppy disk drive 1351 stores the O8 program and also
Disk drive 1361 stores data and character patterns in addition to the contents of the floppy disk.

(IV) The parallel I10 board (123) has a Q6-bit parallel interface t'A? It interfaces with each I10 of the printer 1331, scanner 1332, and sorter 1333. The board 123 is equipped with an I10 processor, and depending on the parameters from the CPU 121, images up to A3 can be printed or read from the scanner 1332, and each J/0
Performs a series of controls for equipment. Data is transferred directly to bit map memory 122 over private bus 1335 without going through local bus 1334f.

Note that if the I10 processor is removed from the parallel I10 board 123, it becomes a slave I/O board, and the CPU 121 can directly control the I10 device.

(■) Image processing v1 (The unit board 124 is a board for data compression/decompression. It decompresses compressed data from the local network using the bit map memory 122, and compresses data from the scanner 1332. and prepare to store it on disk.

By using the Huff, 1335, the local bus 1334 can be freed up for other processing, increasing system throughput and increasing I/O.
Lo processing can be sped up.

011) Individualized memory access method: Memories are arranged in a continuous address space in a dual boat configuration, but operate independently within a certain address range. In other words, if one boat accesses a certain address range (minimum 128 Kbytes, maximum 512 bytes), addresses outside that address range can be accessed simultaneously from the other boat. , the processing efficiency and processing speed of the system are improved, and multitasking becomes possible.

4v) Double capacity of image data memory...bits,
The map memory 122 has a capacity for one page of A3 size as a memory for image data of 12 images per sheet, so when printing A4 size, two consecutive pages can be read out.

Next, the operation of the software in print station 12 will be explained.

(a) System initialization...? tj+! ! After turning on, each board of the system is initialized, working memory 127 &, T predetermined parameters are set, and then 03 if is loaded onto the system memory. The loaded OS initializes the system name I10 and loads the station program.

After checking the contents of the disk and checking the status of each I10, the station program is stored in a predetermined location in memory. Note that the power-on diameter puto is loaded from the floppy disk, and the reputo is loaded from the hard disk.

011) Input document from local network
They are classified into ``Normal'' and ``1 Limited Express,'' and are spooled in the order of input. Input from scanner 1332 is spooled as a local copy, with priority over any document input from the local network. However, if there is no job on the disk and only one page of data is received, data processing and printing are performed without spooling. Ov) When receiving a job, calculate the free area of the disk based on the number of pages, and if it exceeds the number, notify the overflow.

(v) When all jobs have been stored on the disk, a notification of receipt completion is sent back. (V-When receiving a job, calculate the processing time for the number of existing jobs, and send the received job end time jv in response to a request from the station.

& If automatic reception is received during standby mode (at night, etc.), the power is automatically turned off for spooling, and after reception is complete, the power is turned off again.

Change the magnification in 0.1 units up to 2x. In addition, if there is no designated 7-ont, a similar font is determined and used. Furthermore, if there is no designated character generator, an existing character generator is used to generate the character. Also, according to an instruction from another station, it is spooled to [phase], and printout processing is performed based on a judgment based on the bus word input from the console.

(d) Print out... (1) Status
For reading, the status of the printer 1331 such as paper size, orientation, toner, heater, etc., and the status of the sorter 1333 such as jam, number of bins, and stock amount of tacks 5 in the paper take-out bin are read from each I10.
