Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Industrial Application Field) The present invention relates to an electronic filing device that processes data using, for example, an optical disk.

(Prior Art) Currently, in offices, in addition to regular documents and drawings (image data) on paper, documents created with word processors (consisting of character code data), personal computer drawing data, CAD (computer a)
There are drawings (consisting of vector code data) created using IDEED DESIGN). Document data created with these word processors and drawing data created with personal computers and CAD are stored on floppy disks (magnetic storage media), but the problem is that there is an overflow of drawings and document data in various media. The current situation is that

Therefore, a large amount of image data such as documents and drawings is read with a two-dimensional scanning device (scanner), this read image data is stored on an optical disk, and any stored image data is searched from the optical disk. An electronic filing device that reads data has been put into practical use.

Recently, such electronic filing devices have come to handle not only image data read from a scanner, but also code data such as document data or drawing data stored on floppy disks.

However, even when data stored on a floppy disk is stored directly on an optical disk, there is no device that can handle it using the same management system as image data, and there are no devices that can handle it using the same management system as image data. In this case, it is common to use different systems depending on the type of medium being handled, which has the drawbacks of complicated processing and low efficiency.

Therefore, an electronic filing device that can handle and manage document data and drawing data stored on a floppy disk in the same way as paper drawings has been considered (Japanese Patent Application No. 82-230020).

In other words, vector code drawing data retrieved from a floppy disk or optical disk is converted (expanded) to image data, that is, vector-raster conversion is performed to perform drawing processing, and character code document data is converted to image data. (Development) That is, a code-image conversion is performed to perform drawing processing, and the image is displayed on a CRT display device, printed out on a printer, or registered on an optical disc.

However, with such devices, if the data expansion format is incorrectly stored when storing data on an optical disk, the data cannot be correctly expanded and displayed on the display device during retrieval. There were some drawbacks.

(Problem to be Solved by the Invention) As described above, the present invention eliminates the disadvantage that when retrieving data from a storage medium, the data cannot be correctly expanded and displayed on a display device. To provide an electronic filing device capable of correctly displaying data on a display device even if the data is stored in an incorrect data expansion format when searching for data.

By arbitrarily moving the cursor on the RT display device 24 vertically or horizontally and giving instructions at the desired position, you can change the display content where the cursor is located (for example, various modes, editing images, cutting and pasting). range, icon, etc.).

Next, how image data and code data are managed in a unified manner will be explained from the viewpoint of document management.

That is, the document management system in this embodiment has four levels: cabinet, binder, document, and page, and the cabinet is associated with one side of the optical disc 19. A plurality of binders can be defined in the cabinet, and up to about 30,000 documents can be registered in the binder. The search title for each document is the basic unit of the ring, and in addition to the title, annotations (document description)
can be added. Further, a document can be made up of information in units of multiple pages.

This kind of management system takes into account consistency with paper files, and a page corresponds to one sheet of paper document, but code data is also managed at this page level. There is. In other words, image data on one sheet of paper, data on one floppy disk (volume-bulk data), one
A page is either file data on two floppy disks or data obtained by merging these three types of data.

As a result, for example, in one document, a group of source files (code data) of a predetermined program as the first page,
The second page is the program specifications (code data) created with a word processor, and the third page is the processing results (image data), which previously had to be managed completely separately. can do.

Next, the structure of the control program or software stored in the main memory 13 will be explained with reference to FIG.

This control program is an image input/output processing module]3
b1 Floppy disk read/write (FDR/W) processing module 13c1 Optical disk read/write (ODR)
/W) Processing module 13d1 Display control module 13
It consists of an e1 magnetic disk (MD) processing module 13f1 a drawing processing module 13g, and a filing processing module 13a that controls the entire system.

As shown in FIG. 3, the FDR/W processing module 13c includes an FD registration processing module 50a-.

It is composed of an FD input processing module 50b, an FD search processing module 50c, an FD output processing module 50d1, and various other processing modules.

The FD registration processing module 50a has a file name list table as shown in FIG. This file name list table stores data related to the file name list displayed on the FD registration screen, including the total number of files, file name for each file, file size, file date, and whether it is a file or subdirectory. It is made up of attributes that indicate this file, and a selection flag that indicates whether or not this file has been selected as a registration target. Thus, during the registration process, whether there is a selected file is determined by checking whether there is a file whose selection flag is on in the file name list table.

Although not shown, there is an operation system (O8) that comprehensively manages all of these.

The control flow of the filing processing module 13a at the time of registration will be described below. Filing processing module 13
The operator instructs whether to register image data or register the floppy disk 28a (FD registration) to a.

After inputting a title, in the case of registering image data, the image input/output processing module 13b is called and image data is input from the scanner 20. Next, the display control module 13e is called to check the manually input image data on the CRT display device 24, and then the ODR/W processing module 13d is called to display the input image data as C0.
The data is compressed by the DEC 36 and recorded on the optical disc 19. Thereafter, the MD processing module 13f is called, and the address where the image data on one optical disk is stored together with the input title data is registered in the magnetic disk 27a.

In case of registration from floppy disk 28a, FD
Call the R/W processing module 13c.

The designation and processing of floppy disk units or file units, which will be described later, are executed within this FDR/W processing module 13c.

The FDR/W processing module 13c takes out necessary data from the floppy disk 28a based on instructions specified by the operator, stores it in a specific format in the page memory 14, and returns the data. This includes a type flag indicating the type of data to be registered, and the type of data to be registered is set. The details will be described later. Here, if there is a request to display the contents, by calling the display control module 13e,
You can check the file contents. Further, in response to an instruction to execute registration, the filing processing module 13a calls the ODR/W processing module 13d together with the start address and data length of the code data, and records them on the optical disc 19.

If it cannot be stored in the page memory 14 at once,
The FDR/W processing module 13c and ODR/W processing module 13d are called repeatedly. After the recording is completed, the MD processing module 13f is called and the address where the code data on the optical disk 19 is stored is recorded on the magnetic disk 28a together with the input title data, as in the case of recording image data.

Next, the control flow of the filing processing module 13a during a search will be explained. After the operator inputs a search key (keyword, keyword) for the search, the MD processing module 13f performs the search process, and the search results are displayed on the CRT display device 24.

A search request for the optical disk 19 is output to the ODR/W processing module 13d in accordance with the designation of the search document from the operator. At this time, the ODR/W processing module 13d refers to the data header section (described later), checks the type flag, and in the case of image data, performs decompression processing and then stores the image data in the page memory 14.

On the other hand, in the case of code data, the page memory 14
Store in.

When the operator issues a display request for search results, the filing processing module 14a refers to the type flag, checks whether the data can be displayed, and if the data is displayable, calls the display control module 13e and performs the search. The results are displayed on the CRT display device 24. If the data cannot be displayed, an error message will be output. The display control module 13e refers to the type flag, performs processing according to each of the image data and the code data, and displays the CR.
It is displayed on the T display device 24. Further, when the operator issues a request to output the search results to the floppy disk 28a, the FDR/W processing module 13c is called and the write process to the floppy disk 28a is executed.

Since inputting a file name during writing is executed by the FDR/W processing module 13c, there is no need to consider the filing processing module 13a.

Next, the format of the code data and image data stored in the page memory 14 and the optical disc 19 will be explained with reference to FIGS. 5 to 9. In this embodiment, the target floppy disk 28a is 5.25 inches, and the target file is an OS file (specific OS file).
8 as the target floppy disk 28a.
The format of the optical disk 19 is determined so that the target file can be recorded as an inch, 3.5 inch, magnetic disk, magnetic tape, or as another OS file.

As shown in FIG. 5, this format is composed of a data header section and a data section corresponding to one page of data on the optical disc 19.

The data section stores data corresponding to a plurality of modules. For example, if the data equivalent to one page consists of three modules: a worksheet data file, a graphic data file (net file), and a developed image (plotter file), the number of modules is "3". Become.

The data section consists of a main header section and a subheader section. As shown in Figure 6, the main header section contains total data length (4 bytes), total header length (2 bytes), registration date (4 bytes), number of constituent modules (2 bytes), and specific application flag (2 bytes). ), and a spare (2 bytes), making it a 16-byte configuration.

Drawing data created by CAD etc. includes, for each drawing, a worksheet file generated during operation with the user on the CAD, a net file that describes the mutual positional relationship and connection relationship of parts in the drawing data, and those relationships. Multiple files are generated, such as a plotter file (vector data) that is written in a format that can be output to a printer or plotter. Use a drawing management application to manage these multiple files.
Related files are treated as one page, and managed collectively while maintaining an organic relationship with each other. This processing can provide an efficient working environment and improve processing.

For example, for design drawings, drawings of individual parts, etc.
By collectively storing drawings showing the positional relationships of each part, related data can be retrieved immediately even when not being created.

In addition, document data created with a word processor is
A plurality of files are generated, such as a document file and a custom character file that registers different custom characters used for each document. Using a document management application, these files are collectively managed with each related file as one page, while maintaining an organic relationship with each other. This processing can provide an efficient working environment and improve processing.

Further, the subheader section is composed of as many subheaders as specified by the number of modules in the main header section. Types of subheaders include image data header, FD
- There are three types: bulk data header and file data header.

As shown in FIG. 7, the image data header includes subheader length (2 bytes), type flag (2 bytes), data address (4 bytes), data size (4 bytes), compression format (2 bytes), and MH.

MR, etc.), scanning density (2 bytes; 200 dpi.

300 dpj, etc.), image size (4 by I-; A4,
B4, A3, etc.), and an option area (0 to n bytes).

As shown in Figure 8, the FD-pack data header includes subheader length (2 bytes), type flag (2 bytes), data address (4 bytes), data size (4 bytes), device flag (2 bytes), density flag (2 bytes),
OS flag (2 bytes), volume name (12 bytes)
, and an option area (0 to n bytes).

As shown in Figure 9, the file data header includes subheader length (2 bytes), type flag (2 bytes), data address (4 bytes), data size (4 bytes), device flag (2 bytes), and density flag. (2 bytes),
OS flag (2 bytes), volume name (12 bytes)
, directory entry data (32 bytes), and option area (0 to n bytes).

The type flag indicates image data or volume data (FD-
file data) or OS file data, and in the case of file data, the type of data, i.e. CA
This indicates the type of Dl, CAD2, word processor, etc.

Further, the most significant bit of this type flag is an imageable flag indicating whether the data is displayable data or not.

For example, this bit is set in the case of image data or document data, and is not set in the case of command data such as object code data.

The data address and data size of these data headers indicate the address where each data itself is recorded and its size.

The device flags in these data headers are flags that indicate which size floppy disk 28a the data comes from; for example, a 5, 25-inch, 3.5-inch, or 8-inch floppy disk 28a is set. There is.

The density flags of these data headers are flags for identifying whether the recording density of the floppy disk 28a is 2DD or 2HD. Furthermore, when a magnetic tape is connected, this flag is used to identify that t[toObpi is 6250 bpi.

The OS flags in these data headers indicate the type of OS, e.g.
2. It shows the OS, etc. that the word processor runs on.

An example of how to use the option area of the FD-pack data header is to use the volume (floppy disk 28a) described later.
There is a record of the directory browsing data within the entire directory.

The directory entry data area in the file data header contains O8 on the target floppy disk 28a.
The 32-byte data (file name, file size, creation date, etc.) recorded by is copied and recorded. The data in this has a different configuration depending on the O8 indicated by the OS flag.

Further, the main memory 13 is provided with a module management data storage area 13□, a header management data storage area 132, and a data header part storage area 133, as shown in FIG.

In the module management data storage area 131, the type, file name, recording address in the page memory 14, and size of each currently selected module are stored in correspondence.

The module management data storage area 131 stores the number of currently selected modules, the recording address in the main memory 13 (data header storage area 133) where the data header data is stored, and the size. It is now possible to do so.

Next, using the display example in FIG.
F as the display screen 24a of the RT display device 24
The D registration screen will be explained.

That is, a list of file names in the floppy disk device 28 indicated by "device" is displayed. In this example, a 5.25-inch floppy disk drive 28
is selected as the input device. Other devices include 3.5 inch floppy disk drive 28
is also selectable. Below "Device" is "Volume Name", which displays the volume name of the floppy disk 28a in the currently selected floppy disk device 28. For example, rSAMPLE
The volume name is l.

``Direct Name'' displays the name of the current directory of the currently displayed file name.

For example, rDATA/TEXTJ is displayed, and a list of file names in this directory is displayed in the file name display area 60.

In the file name list, each line corresponds to one file, and the file name, file size, and file creation date are displayed.

In the case of a subdirectory, the file name is displayed surrounded by "<" and ">". ``<,>J represents the current directory, and ``<, >j represents the parent directory.

In order to move to the desired directory, the operator can directly enter the directory name in the "Directory Name" field using the keyboard 23, or press 1<" in the file name list.
The directory surrounded by ">" is selected using the keyboard 23 or the mouse 29.

"-Target" is used to specify a wild card for the file name to be displayed in the file name list.For example, it is [*, *J, which means that all files in the current directory will be displayed. It looks like this. Here, “c*
, *J from the keyboard 23, only file names starting with "C" are displayed as a file name list.

The "number of files" is the total number of files in the currently displayed file name list.

In the file name list, there is the current file indicated by a highlighted frame, and on the right side of the file name list are "△" and "".
or function key "F5; Previous file", 1
This current file can be moved by instructing "F6; Next file". Figure 10 shows - 1F6; Next file when the soil file is selected.
This is the screen with the command 5 times, for example, rcONI
The files named o and Cl are selected as the current files.

When checking the contents of the current file, you can instruct "F3: Display contents" to display the contents using the method specified in "Data type". As shown in FIG. 11, this content display shows the files rcONIo and Cl or the "data type" as text.

As the "data type", it is possible to specify text data consisting of Shift JIS code, drawing data created by CAD, document data created by a word processor, etc.

When "F3; Display contents" is instructed, the FDR/W processing module 13c calls the drawing processing module 13g using the code data and data type of the current file as parameters, and displays the contents.

At this time, the drawing format file data in the floppy disk 28a or the magnetic disk 27a is also output as a parameter to the drawing processing module 13g.

If the operator makes a mistake in the type of data, the content display will be meaningless. In this case, the operator can specify the type of data correctly and display the raw code data of the client file in hexadecimal representation (DUMP display) as shown in FIG.

This allows the operator to check the contents of the current file more accurately.

In addition, in the content display and DUMP display screens shown in FIGS. 12 and 13, the displayed data can be scrolled up and down by specifying "Δ" and "".

Next, regarding the operation of the FD registration process, FIG.
This will be explained with reference to the flowchart shown in (C). That is, the filing processing module 13a calls the FDR/W processing module 13c when registering the floppy disk 28a, and the FDR/W processing module 13c
calls the FD registration processing module 50a.

Then, the FD registration processing module 50a performs the process shown in FIG.
As shown in the flowchart a), first, it is determined whether the internal mode is in batch FD registration (normal).

If the result of this determination is the normal mode, input by the operator using the keyboard 23 or mouse 29 is awaited, and processing corresponding to the input data is performed.

That is, a file (code data) to be registered on the optical disc 19 is selected by inputting a "selection key" on the keyboard 23 or by using the mouse 29 to indicate the current file with an emphasis frame. For example, rc
The files ONIQ and Cl are displayed with halftone dots, indicating that they have been selected as files to be registered.

In this state, by instructing "Fl;Execute", 5.2
rcON I in 5-inch floppy disk 28a
Files O and Cl are read into the main memory 13, and text (data type) is set in the type flag in the subheader section. In addition, data such as file name and file size are set in necessary locations in the main header section and file data header section, and furthermore, the drawing format file data is set, and the starting data address and data length in the page memory 14 are set in the filing processing module. Output to 13a.

It also calls the FD input processing module 50b and stores the code data in the page memory 14 on the floppy disk 2.
8a, and receive the start address and data length. After that, if the selected file remains in part of the file name, the internal mode is set to batch FD registration mode, and the start address and data length of the data read into the FDR/W processing module 13c are sent to the filing processing module 13a. Output and exit from this module.

To check whether this selected file remains, check the file name -
A process is performed to check whether there is a file whose selection flag (flag indicating whether or not it is a registration target) in the list table is on.

Further, the filing processing module 13a records the data on one optical disk based on the start address and data length of the supplied data, and additionally registers a title on the magnetic disk 27a if there is title-added data.

After that, the filing processing module 13a again
The FDR/W processing module 13c is called for FD registration, and the FDR/W processing module 13C calls the FD registration processing module 50a.

This process is repeated until the FDR/W processing module 13C outputs an end status or until the maximum number of pages of data are registered on the optical disk 19.

Furthermore, when the operator inputs termination, the termination status is supplied to the FDR/W processing module 13C. If the operator makes another input, another processing module is called and the process returns to waiting for input from the operator.

In addition, if the result of the determination is batch FD registration mode, if the operator does not input a stop command and a selected file exists, the FD input processing module 50b is called and the FDR
/W processing module], 3c outputs the start address and data length supplied from the floppy disk 28a to the filing processing module 13a, and exits from this module.

Then, when a stop command is input or there are no more selected files, the internal mode is set to normal mode and the system waits for input from the operator.

Further, as shown in the flowchart shown in FIG. 14(b), the F and D input processing module 50b searches for the file selected from the file name list table, and stores the file data corresponding to the searched file. The information is read from the floppy disk 28a to the page memory 14. If the operator has set the registration mode to code data, set the main header and code data header for code data, and if the operator has set it to image data, convert code data to image data (image data). In order to do this, the drawing processing module 13g is called. At this time, code data as the input parameter register 31, the type of data specified by the operator, the imaging format, and drawing form file data (described later) are output to the drawing processing module 13g.

After this, a main header and an image data header for image data are created.

Next, if the operator has selected automatic title addition, title data to be additionally registered on the magnetic disk 27a is created.

Then, the selection flag in the file name list table corresponding to the file read from the floppy disk 28a is set to OFF, the halftone dot display in the FD registration screen is erased, and the
The D registration processing module 50a outputs the start address and data length of the data set in the page memory 4 to the filing processing module 13a, and exits from this module.

Furthermore, as shown in the flowchart of FIG. 14(C),
If "F2: Title display" is input, the title data related to the currently selected file is displayed in the 15th
The display is displayed as shown in the figure, and when the operator inputs "F9;Confirm", this display is erased and the display returns to the display shown in FIG. 11.

Also, if "F3; Display contents" is input, the file indicated by the current file will be displayed on the floppy disk.
8a to the page memory 14, and the drawing processing module 13g reads this data, the data type specified by the operator, the imaging format, and the drawing form file data.
and display it as shown in FIG.

In this state, if "F5; Previous file" or "F6; Next file" is input, the current file is moved and the moved current file is transferred to the floppy disk 28.
The data is read from a and subjected to drawing processing by the drawing processing module 13g.

If "rF4; DUMP display" is input, the data type is changed to DUMP, the drawing processing module 13g is called, and the data is displayed as shown in FIG. At this stage, if "F4; VRC display" is input, the data type is returned to the original and the drawing processing module 1
Call 3g and display as shown in Figure 12. Then, when the operator inputs "F9;Confirm",
This display is erased and the display returns to the one shown in FIG.

In addition, when "F4; File name list display" is input, the files on the floppy disk 28a are searched for by the device, directory, and list target specified by the operator, and the total number of corresponding files and each Set the file data in the file name list table and redisplay the file name list on the FD registration screen.

In this state, if "F5; previous file" or "F6; next file" is entered manually, the current file within the file name part is moved to the previous or next position, and the emphasis frame is redisplayed.

When "F7; Select all files" is input, the select flag for all files other than subdirectories in the file name list table is set to ON, and halftone dots are displayed on the corresponding files in the FD registration screen. If "F8: Deselect all files" is set to = 38 - manually, set the all selection flag in the file name list table to OFF and erase the wire mesh dots in part of the file name on the FD registration screen. .

If "F9. Image format" is input, the 16th
As shown in the figure, an imaging format screen is displayed, and the current format, designated size, designated density, designated drawing direction, form overlay, and designated form are displayed, and the operator is prompted to set them.

When the selection key is input, the following processing is performed according to the attributes and selection flags in the file list table of the current file.

That is, if the attribute is a subdirectory, the directory name is updated in order to move to the corresponding directory, and a file name list is displayed at this point. If the attribute is file, if the selection flag is off, it is turned on and displayed as halftone dots, and if it is on, it is turned off and the halftone dots are erased.

Also, "processing unit", "data type", "automatic title addition", "device name", "directory name", "-
If the "view target" is manually set, update its settings. After performing these processes, the display returns to the one shown in FIG. 11.

Next, automatic title addition will be explained.

In other words, files (code data) are stored on one optical disk.
When registering the file name,
Titles (keywords) such as file size can be registered on the magnetic disk 27a. For example, when the file rcON I O, Cl is selected, by instructing 1F2; Display title,
A title display screen as shown in FIG. 15 is displayed. This display screen displays a title (keyword) that is automatically added to the magnetic disk 27a when code data is registered on the optical disk 19.

For example, "file" as the processing unit, "text" as the data type, and rsAMPL as the volume name.
EJ, rDATA/TEXTj as directory name
, the file name is rcON I O, Cj, the file size is r4857j, and the file size is r1986/=40-2/21J. If [volume name] is selected as the processing unit, two keywords, processing unit and volume name, are displayed, and are registered on the magnetic disk 27a during execution.

The operator determines whether or not to automatically add this title to the magnetic disk 27a.
The selection is made by selecting "Yes" or "No".

If "Yes" is selected, the FDR/W processing module 13c sets title data to be automatically added in the main memory 13, outputs the start address and data length of the code data to the filing processing module 13a, and The start address and data length of the title data in the main memory 13 are also output. Thereafter, the filing processing module 13a records the code data in the page memory 14 on the optical disk 19, and records the title data on the magnetic disk 27a.

Next, a description will be given of batch registration in which multiple files are registered at once. That is, each file in the file name list can be selected using the "select" key on the keyboard 23 or the mouse 29.
This is done by selecting a plurality of files and instructing "Fl;Execute". For example, as shown in FIG. 17, a 5.25-inch floppy disk 28a
All files in DATA/TEXT are selected.

To select all files on the floppy disk 28a, in addition to selecting them individually using the keyboard 23 or mouse 29, it is also possible to select "Fl; select all files". - If you wish to cancel the selected file, select it again using the keyboard 23 or mouse 29 to cancel the selection, and the halftone dots will be erased from the display. If all files are to be deselected, this can also be done by instructing "F8; Deselect all files."

When “Fl; Execute” is instructed, the display in Fig. 17 changes to the first
The display is changed to that shown in FIG. 8, and 26 files (code data) are sequentially read from the floppy disk 28a and registered on the optical disk 19.

In this case, each time a file is registered on the optical disc 19, the halftone dot of the corresponding file in the filename-group is erased, and the registration page at the bottom of the screen is counted up by one. In FIG. 18, files rCAT and Cl have been registered on the optical disk 19.

This process is stopped by instructing ``rFlo;Stop'' during batch FD registration. Also, click “Fl: Execute” again.
By instructing , batch FD registration is performed sequentially starting from the file where halftone dots are displayed.

The FD registration process reads a file (code data) from the floppy disk 28a, adds a header to it, and registers it on the optical disk 19. As a result, by registering code data such as text data, CAD data, word processing data, etc. in the floppy disk 28a on the optical disk drive 9, it can be retrieved when necessary and sent to the CRT display device 24 from the drawing processing module 13g. It is possible to display the data, print it with the printer 25, write the code data on the floppy disk 28a, and modify it on another computer.

In addition, by setting "Registered data" on the FD registration screen to "Imaging data", you can
When code data is registered from 8a, it is converted into an image by the drawing processing module 13g, and this dot image data is recorded on the optical disc 19. As a result, the drawing processing module 13g
Even if it takes a considerable amount of time to develop vector code data into two-dimensional dot image data, by developing it in advance at the time of registration,
It is possible to prevent the time consuming process required when searching and displaying code data in the optical disk 19, and to shorten the search time. That is, by recording the image data in the optical disk 19, there is no need to call the drawing processing module 13g during search display and printing, and high-speed processing can be performed.

Furthermore, the operator can select "registered data" from among three types: "code data,""imagingdata," and "code+image."

"Code data" is for registering the code data in the floppy disk 28a as is. "Image data" is created by converting the code data in the floppy disk 28a into an image by the drawing processing module 13g.
This image data is registered. Further, "code+image" is registered as a set of code data and image data in the floppy disk 28a.

Furthermore, when creating an image, it is possible to specify the image size, resolution, portrait, and landscape.

Next, the format for creating an image will be explained. 1st
In the display shown in Figure 1, specify "F9; Image format" and use the image format property sheet 61 shown in Figure 16 that is displayed in response to this instruction to change the format, that is, code data, especially word processing data, etc. The paper size, resolution, etc. for printing are set in advance. "Auto" in the imaging format in this imaging format property sheet 61 means to create an image in a format preset in the code data, and "specified" means "specified size" set by the operator. , "designated density", and "designated drawing direction".

Also, when creating an image, you can specify the form that will be used as the mount.

This designation is performed by setting "Form Overlay" in the imaging format to "Yes" and setting "Specified Form". This imaging format information is output to the drawing processing module 13g together with the code data and the drawing form file data, and is converted into an image there. Ru.

Next, the search process will be explained with reference to the flowcharts shown in FIGS. 19(a) and 19(b).

First, the optical disc 19 is loaded, a binder to be searched is specified on the search screen, and the binder is opened.

Then, on the logical search screen, set the key value of the document to be searched and instruct ``Start Search.'' Then, a list of document titles that meet the set key value conditions is displayed. Here, if you set the document and page to be extracted and instruct "document output", an output destination selection property sheet will be displayed. From this display, when the user selects ``Save rFD'' and instructs ``Confirm,'' an FD output screen as shown in FIG. 20 is displayed. Furthermore, if the document or page to be extracted is not specified, the first document displayed on the extraction screen is targeted, as shown in FIG. Furthermore, the setting of the document or page to be extracted is changed by pressing the next document, previous page key, or next page key on the keyboard 23.

Information regarding the output target and output light is displayed on the FD output screen shown in FIG. This output target is a file corresponding to the document or page extracted by the search process, and for this file, the original device at the time of registration, the volume name added to the original device, and the file name specified at the time of registration. The data type and file name are displayed. Of these, only the data type attribute can be changed. As a result, even if the data type is incorrectly specified during registration and a legitimate image cannot be obtained when displaying the search target content (described later), you can select another data type and display the content again. is now possible.

In addition, on the FD output screen, the data type specified at the time of registration is displayed, and - temporal data type selection,
Change states are also indicated using distinguishable means.

However, the attribute change described here is effective only when displaying the search target content, and it is only possible to change attributes that have already been registered on the optical disk 19. In addition, the floppy disk 28a is
You can also specify the type of data you want to view above file data here. The output light is the floppy disk 28a on which the searched file is to be output.
Regarding this floppy disk 28a, the device, the volume name attached to the device, the directory name where the file to be displayed as a list in the file name display area 70 exists, and the file name display area 7
Conditions for items to be listed in 0, number of applicable files,
Each item of the file name on the floppy disk 28a of the file to be output is displayed, and the file name display area 7
A list of file names is displayed in 0.

Of these, the operator can input everything except the volume name and the number of files, and by moving the cursor within the file name display area, a directory or file can be selected.

The operator selects the floppy disk 28a which becomes the output light.
After setting the floppy disk into the floppy disk device 28, instruct "print document" and "save rFD" on the logical search screen. As a result, the FD output processing module 50d accesses the floppy disk 28a set in the floppy disk device 28 set as an output optical device, reads the volume name, and displays it. Also, from among the files in the directory set as the output optical directory, the information (name, size, update date and time) of files that meet the conditions set for viewing is read, and this information is displayed in the file name display area. Display a list within. As a result, the floppy disk 2 which is the output light
A list of files in 8a can be obtained at any time.

Also, when the operator moves the device selection cursor using the arrow keys on the keyboard 23 or instructs to change the output optical device by using the mouse 29, the same way as when the FD output process is started from the search process. Data regarding the output light is updated on the FD output screen. The output light direction can be specified by directly inputting the directory name or by moving the cursor within the file name display area. In addition, the directory name function allows you to input the directory name from the root directory using the keyboard 23 after specifying the directory name item using the arrow keys on the keyboard 23 or after specifying the directory name item using the mouse 29. There is. Furthermore, to specify a directory in the file name display area 70, specify the file name - the directory being viewed with two mice, move the cursor, and then specify the same directory again with two mice, or use the keyboard. After moving the cursor to the directory being viewed by using the ``previous file'' and ``next file'' keys of 23, the directory is specified by pressing the ``select'' key.

As a result, when the output light directory is specified, the system moves to that directory, the directory name item is updated on the FD output screen, and the data regarding the output light is updated.

When specifying a directory in the file name display area, selecting a file will have no effect. However, when a file is selected and the cursor is placed on the file, the contents of the file can be checked and displayed using the contents display function described later.

Some of the functions on the FD output screen in the CRT display device 24 include "Execute", "Display contents of output target", "Display contents", "Display file name list", "Previous file", "Next file", "-Batch output", "Cancel"
functions are assigned. These functions may be assigned to keys other than function keys, as long as each function can be instructed with a simple operation.

When "execution" of a part of the function keys is instructed, the output target file is outputted with the designated file name to the designated directory in the output optical floppy disk 28a.

In this case, the file name on the floppy disk 28a after output can be input from the keyboard 2B on the FD output screen. Unless otherwise specified, the file name will be the same as the searched file.

When you specify "Display output target content" for some of the function keys, the content of the searched file, that is, the content of the file displayed as the output target, is displayed as the output target content display screen, as shown in Figure 18. Ru. There are two types of display: vector-rusk conversion expansion display and dump display, and selection between these two can be made arbitrarily using function keys F8 (DUMP) and F9 (confirm).

The vector-rusk conversion expansion display interprets file data expressed as vectors and develops it into a bitmap suitable for rask display. The contents of the file are displayed according to the instructions provided.

In this case, if the "data type" which is the attribute information of the searched file is incorrect and a regular image cannot be obtained, you may need to select another correct "data type" and try again. It is now possible to display it.

Such temporary selection and change status of data type is now displayed on the FD output screen using a means that can be distinguished from the data type specified at the time of registration. ing.

The dump display displays the contents of the file in hexadecimal ASCII code, regardless of the instruction selected in the "data type" item.

At this time, the displayed output target file name, paper size and density (200/400) when converted to an image
, the drawing direction (vertical/horizontal) is displayed on the output target content display screen, as shown in FIG.

In addition, if all the contents cannot be displayed on one screen, such as in a text file, point the upward/downward arrow icons on the output target contents display screen using the mouse 29 or keyboard 1. By pressing the up/down arrow keys 23, it is possible to move to the previous/next page within the same output target file, that is, update the output target content display screen. Furthermore, if a "cancel" command is given during content display, the image development process will be canceled.

Note that all the functions that can be instructed on the output target content display screen are valid even during the display, and the display is stopped in the middle according to a predetermined instruction, and a new instruction is followed.

In addition, when "1 confirmation" is instructed with the mouse 29 or the keyboard 23 on the output target content display screen, the output target content display ends.

When you instruct "Display contents" for a part of the function keys, the contents of the file on the floppy disk 28a selected by the cursor in the file name display area are displayed on the contents display screen, as shown in Figure 22. . There are two types of this display: vector rask conversion expansion display and dump display.Select these two types by pressing the function key F8 (
DUMP) and F9 (confirm) can be used as desired. When performing vector rask conversion expansion display, select the data type using the "Data type" item related to the output target, and then select the "data type" that matches the selected file data. ing. The selection of the "data type" at this time is temporary and does not affect the attributes already registered on the optical disk 19 in any way.

In this case, the type of data registered on the optical disk 19 and the type of data temporarily selected are displayed simultaneously on the FD output screen using means that can distinguish them.

In addition, the file name on the floppy disk 28a being displayed, the paper size when imaged, the density (200/400), and the drawing direction (vertical/horizontal) are displayed as shown in Figure 22. displayed on the screen.

-56= Furthermore, if all the contents cannot be displayed on one screen due to a text file or the like, the screen can be updated in the same way as in the case of the output target contents display screen.

Furthermore, when the cursor is on a directory in the file name display area, a system message indicating that the contents cannot be displayed is displayed at the bottom of the FD output screen, and the screen does not move to the contents display screen.

In addition, when "previous file" or "next file" is specified using two mice or the keyboard 23 on the content display screen shown in FIG. 22, the file name in the file name display area on the FD output screen - The files immediately before and after the currently displayed file are newly selected and their contents are displayed.

In accordance with this newly selected content display, the file name on the corresponding floppy disk 28a, the paper size and density (200/400) when converted into an image,
The drawing direction (vertical/horizontal) is also updated on the content display screen.

When displaying the contents, if an error occurs such as the floppy disk 28a not being loaded, the specified file not being found, or a file reading error, the bottom row of the contents display screen (lower row of size: density 2) will be displayed. Display a system message notifying you of this and clear the content display area.

As a result, the output target file is also displayed on the output optical floppy disk 2 by "output target content display" and "content display".
The contents of the files in 8a can also be viewed freely.

When you specify "File name list display j," the output light floppy disk 28 is displayed according to the device, directory, and target for output light set on the FD output screen.
Necessary information is read from a, and a list of file names of the corresponding file is displayed in the file name display area. When this is instructed when the floppy disk 28a is replaced, a new list of file names is displayed.

When you specify the function key 1-extraction power for a part, the batch output property sheet is displayed as shown in Figure 23, and you can select either 1 document - printing output or all documents - batch output. There is.

This single document extraction power is to output all pages of the document containing the currently searched file to the floppy disk 28a. Furthermore, the ability to extract all documents means outputting all pages of all retrieved documents to the floppy disk 28a. When "confirm" is instructed after selecting one document - extraction power or all documents - extraction power, the extraction power property sheet is closed and the previous page of the specified document is sequentially output to the floppy disk 28a. Then, when the output processing of the previous page of the document to be outputted to the FD is completed, the screen returns to the FD output screen shown in FIG. 20. Furthermore, if "cancel" is instructed during the output process on the FD output screen, the extraction force process is canceled and the screen returns to the FD output screen shown in FIG. 20. The FD output processing up to this point is valid. Furthermore, when "confirm" is instructed on the extraction screen, a confirmation display of the searched file is performed. If the searched file is not an image file but code information that cannot be displayed, the file's attribute information, that is, the file name,
Creation date etc. are displayed.

In these search processes, the FD search processing module 5
0C reads data onto the page memory 14 via the interface circuit 17 if it is set in the optical disc 19 or the optical disc device 22. If this data is image data, it is transferred to the display memory 15 as it is, and the data is transferred to the CRT display device 2 via the display control unit 16.
4 will be displayed. Also, if the data is code data,
When the image-capable flag is set, the code is displayed on the CRT display device 24 by requesting a drawing processing module 13g, which will be described later, to perform code development drawing processing.

Further, data read from one optical disk is stored on the page memory 14, and attribute information such as the original device, volume name, data type, etc. added at the time of registration is also stored on the page memory 14. These attribute information are displayed on the FD output screen as data related to the output target.

When the output target content display is instructed, the display memory 15
Set the area above, the area identifier, page memory 1
The type flag to be output on 4 is output to the drawing processing module 13g, and a code development drawing is requested. As a result, the drawing processing module 13g can control the display memory 15.
The code data is interpreted, developed and drawn according to the data type in the area reserved above.

In addition, in these search processes, when FD output is instructed and the floppy disk 28a of the output light is loaded into the magnetic disk device 28, the FD output processing module 50d outputs the floppy disk of the output light via the interface circuit 17. The information regarding 28a is read and displayed on the FD output screen as information regarding the output light.

That is, the volume name added to the output optical floppy disk 28a and a list of file names of files that exist in the directory designated on the FD output screen and satisfy the conditions to be listed are displayed on the FD output screen. When the device, directory name, or item to be viewed is changed on the FD output screen, access the floppy disk 28a and press F.
D The data regarding the output light floppy disk 28a on the output screen is updated.

When content display is instructed, the file specified by the cursor in the file name display area on the FD output screen is stored from the output optical floppy disk 28a to an area secured on the page memory 14, and then stored on the display memory 15. , and the identifier of the area, the identifier of the file data stored in the page memory 14, the identifier of the data type temporarily selected in the data type item related to the output target, and the imageable flag. is output to the drawing processing module 13g to request code expansion and drawing. Thereby, the drawing processing module 13g interprets and develops the code data according to the type of data, and draws the code data in the area secured on the display memory 15.

Also, when instructed to execute FD ratio output, page memory 1
The code data to be output held on the floppy disk 28a is output and saved directly under the directory specified on the FD output screen in the floppy disk 28a with the file name specified on the FD output screen. In this case, data describing the drawing format of the code data may be added as necessary.

Furthermore, the operations of other modules driven when executing the FD search processing module 50c and the FD output processing module 50d are the same as those at the time of FD registration or FD input described above.

Next, when searching for the FD, if "F", confirm is specified, the searched images are displayed for confirmation.

At this time, the filing processing module 13a outputs search data to the display control module and requests it. In this case, functions that can be operated on search data will be explained.

First, the code/image indicator will be explained. That is, as shown in FIG. 24, the document window 8 is used as the display screen 24a of the CRT display device 24.
0 and a frame icon 81. The frame icon 81 includes an image/code identification section 82 that presents the type of document window 80.

The image/code identification unit 82 determines whether the data retrieved and displayed in the document window 80 is stored on the floppy disk 2.
The code data registered from 8a or the image data input by the scanner 20 or the like is displayed. This results in, in the former case, "code"
or the shaded "image" is displayed; in the latter case, the "image" is displayed.

The size and density displayed at the bottom of the image/code identification section 82 are the values written in the code data or the default values of the data in the case of code data, and the actual values in the case of image data. scanner 20
It is designed to show the size and density values read from etc.

Therefore, when a search process is performed, the type of data is determined based on the type flag in the subheader section, and the image/code identification section 82 determines the "code" based on the result of this determination.
, the ``image'' is shaded, or the ``image'' is displayed.

In such a situation, if the expanded format of data is registered incorrectly when registering an image, the correct display will not be made when searching for that data. In this case, the operator first instructs the image/code identification section 82 using the keyboard 23 or mouse 29. Then, a code type change property sheet 83 as shown in FIG. 25 is opened on the display screen 24a of the CRT display device 24, and the operator can use this code type change property sheet 83 to re-specify the correct data type. It is now possible to do this.

That is, as shown in the flowchart of FIG. 26, when a code type change request is instructed, the document window 8
It is determined whether the image displayed on 0 is a code or an image based on the type flag in the subheader section. As a result of this determination, if the image is an image, the process ends. If the result of the determination is that the image is a code, the currently displayed code type is determined by the type flag in the subheader section, and the code type change property sheet 83
Display by. In this case, the area where black inversion is performed indicates the selected type.

As a result, when changing the code type, select it using the keyboard 23 or two mice, change the black inversion state, and instruct "F9: Confirm" to change the code information with the selected code type. A redisplay takes place on the document window 80.

In this case, by instructing ``rFlo;Cancel'' using the keyboard 23 or two mice, the selection is canceled and the original state is returned.

When developing code data such as, the selection of image size and image density specified in the code data,
Alternatively, it is possible to set whether to unfold in the longitudinal direction or in the lateral direction, assuming the paper surface. In this case, regarding the image size and image density, the specific paper size etc. at the time of development are changed, and regarding the format, the method of development is changed.

That is, by pointing (pulling down) the setting change icon 84 using the keyboard 23 or mouse 29, the formatting, image creation, and image creation cancellation icons 84 a, 84 b, and 84 are displayed as shown in FIG.
c is displayed. With this display, by pointing to the icon 84a corresponding to formatting, the shape of the cursor changes, indicating that the mode has been entered. Next, if you pick twice the document window 80 displaying the contents of the file whose format you want to change, as shown in Figure 28,
A formatting property sheet 85 is displayed.

The user instructs the data to be changed using this formatting property sheet 85, and instructs "F9;Confirm".

Thus, when a format change request is issued, it is determined whether the image displayed on the document window is a code or an image based on the application flag in the main header section. As a result of this determination, if the image is an image, the process ends.

Further, if the result of the determination is that the image is a code, the currently displayed format is determined based on the density flag in the subheader section, etc., and displayed using the format setting property sheet 85. In this case, the part where black inversion is performed indicates the selected format.

As a result, when changing the code type, make a selection using the keyboard 23 or two mice, change the state of black inversion, and instruct "F9: Confirm" to change the code information with the selected code type. Redisplay occurs on document window 80.

Further, the image of the coat data is managed in the form of a coat, and does not have image data based on paper, unlike the case where it is input from the scanner 20.

Therefore, when performing image editing on the code data, it is necessary to convert the code data into paper-based image data in the same way as the image input from the scanner 20.

For this purpose, it has a function of converting "code data" into "image data" and allows arbitrary image editing to be performed on images handled by code data. It is also possible to change the format of the image before converting it into an image.

That is, as shown in the flowchart of FIG. 29, by pointing (pull down) the setting change icon 84 using the keyboard 23 or mouse 29, each of the formatting, image creation, and image creation cancellation icons 34 a,
84b and 84c are displayed. With this display, by instructing the icon 84b corresponding to imaging,
The shape of the cursor changes to indicate that the mode has been entered.

Next, by clicking twice on the document window 80 displaying the contents of the file to be imaged, image formation is executed and the display or update is performed.

At this time, the image/code identification section 82
The shaded area is displayed.

When converting data spanning multiple pages, such as shift JIS code data or word processor data, to image data, only the pages displayed in the document window 80 are processed.

Also, if you make a mistake in converting to an image, or if you want to re-image another page using text data, you can return the imaged data back to code data by performing "Cancel image conversion". is now possible.

That is, by pointing (pulling down) the setting change icon 84 using the keyboard 23 or mouse 29, the formatting, image creation, and image creation cancellation icons 84 a, 84 b, and 84 are displayed as shown in FIG.
c is displayed. With this display -70-, the icon 84c corresponding to image creation cancellation is indicated, and the shape of the cursor changes, indicating that the mote has been entered. Document window 8 displaying the contents of the file you want to unimage
By picking 0 twice, unimaging is performed and the display is updated.

At this time, the image/code identification section 82
changed to "code".

However, there are two types of image data: code data converted into an image (displayed as "image" by the image/code identification unit 82), and data input from the scanner 20 or the like. If the data is converted into an image (displayed by the image/code identification section 82 with "image" shaded), the image conversion can be canceled, that is, it can be returned to the code data, and input from the scanner 20 etc. In the case of
This is original image data and cannot be converted into code data.

The internal processing of the imaging process will be explained with reference to the flowchart shown in FIG. That is, when the imaging process is instructed, the displayed code data is saved from the page memory 14 onto the magnetic disk 27a. Next, a storage area of the page memory 14 corresponding to the size of the format corresponding to the code data is secured, and image data obtained by developing the code data saved on the magnetic disk 27a is stored on this storage area. When this development is completed, the image/code identification section 82 is displayed with "image" shaded.

The internal processing of the imaging cancellation processing will be explained with reference to the flowchart shown in FIG. That is, when an instruction is given to cancel imaging, the instructed document window 8
It is determined whether the content of 0 is code data or image data, and if it is other than imaged code data, the process is terminated. Next, the image data on the page memory 14 is erased, and the code data saved on the magnetic disk 27a is restored on the page memory 14.

At this time, the image/code identification section 82 is converted from the "image" shaded display to the "code" display, and the code data is developed on the document window 80.

Next, a specific method for drawing code data will be explained using FIGS. 32(a) to 32(e).

That is, the drawing of the code data is performed by the i card drawing processing module 13g. A drawing routine for actually drawing in the page memory 14 and display memory 15 is built into O8.

The drawing processing module 13g has a function of interpreting code data of different formats and sequentially calling drawing routines built into the O8.

The drawing processing module]-3g is composed of a drawing module main section 61 and an individual data interpretation drawing processing section 62, as shown in FIG.

The drawing module main part 61 is an image input/output processing module as a higher-level application task], 3b,
Based on the request from the FDR/W processing module 13c1 display control module 13e, it activates the lower-level interpretation and drawing processing unit 63a1 necessary for drawing the data, sets the drawing size and format, It manages files that describe drawing data.

The individual data interpretation/drawing processing unit 62 interprets each piece of data and sequentially calls the corresponding O8 drawing routine for each data type. The contents will be dumped.

The drawing module main section 61 includes a command reception control section 7
1. Morphological description information management section 72, modeling processing section 73,
and an individual drawing processing starting section 74.

The command reception control unit 71 is a module that receives requests from higher-level applications and controls the execution flow. The form description information management unit 72 manages the location of drawing form description information that describes attribute information for image development of each code data. The modeling processing unit 73 calculates and sets parameters for arbitrarily setting the size and direction when developing an image.

The individual drawing processing activation section 74 activates the lower-order individual data interpretation and drawing processing section 62 according to the type of data given from the upper application.

As shown in FIG. 34, the format of the expansion request command received by the command reception control unit 71 includes the specification mode, data pointer, data type, drawing location, form, drawing page, format, modeling parameters, and expansion. Consisting of children.

The drawing modes are (1) automatic drawing (drawing in the format described in the data), (2) format specified drawing (drawing by specifying the format from the outside), and (3) modeling specified drawing (drawing by specifying the format from the outside). (Drawing by specifying modeling parameters) 3
There are different modes.

The data pointer indicates whether the data to be drawn is on the page memory 14, if so, a pointer on the page memory 14, and if it is on a file, a file pointer is given.

The data type is the type of data to be drawn,
It is used to determine which lower-level interpretation/drawing processing section 63a1... should be activated.

The drawing location specifies whether to draw on the page memory 14 or the display memory 5.

The form specifies whether to draw on a blank sheet of paper or on a format paper provided by a certain system.

The drawing page specifies the drawing page when the drawing spans multiple pages, such as in a text file.

The format is size, pixel density of the mount (200/400),
This is used to specify the drawing direction (vertical/horizontal). This is to be specified when drawing with Ai format specification or Moring specification drawing. (Modeling parameters are also specified at the time of modeling specification drawing.Here, if the format and modeling parameters are not specified, they will be returned as a return.

The extension is reserved for functional expansion.

Next, how to use the three types of drawing modes will be explained.

That is, when reading code data from the optical disk 19, inputting it from the floppy disk 28a, etc., and drawing the code data from the page memory 14 to the display memory 15, you will not know how large the data will be drawn until you try drawing it. Sometimes you don't know. For example, various drawing data are often defined as different image sizes. Automatic drawing develops this data in the format exactly as it is written in the data.

In addition, the size and density of the drawing area have already been defined, and format-specific drawing is a process of drawing so that the area is appropriately placed.

Further, modeling-designated drawing is a drawing process in which a shape is drawn at an arbitrary position of the drawing location, including enlargement, reduction, and rotation. This is particularly effective when image data is incorporated into another image for display or printing.

The individual data interpretation and drawing processing section 62 is composed of interpretation and drawing processing sections 63a1, . . . that are prepared separately for each data type.

The interpretation drawing processing section 63a includes a command reception control section 81, a drawing form management section 82, an interpretation execution control section 83, and an interface section 84.

The interpretation drawing processing units 63b, . . . also have the same configuration.

The command reception control section 81 is the drawing module main section 61
It receives commands from.

The drawing form management unit 82 manages drawing form description information as attribute information when developing an image of each code data. The interpretation execution control unit 83 interprets the code string of the image data, sequentially calls the drawing routine in O8, and actually issues drawing instructions. The interface unit 84 is for sequentially importing image data or drawing form description information according to their location information.

Next, regarding the operation of each part, first, the expansion of predetermined image data stored on the page memory 14 will be explained as shown in FIG.
This will be explained with reference to the flowchart shown in a).

Based on the type of data given, the drawing module main unit 6] causes the interpretation drawing processing unit 63a (63b, . . . ) corresponding to the data type to be activated by the individual drawing processing starting unit 7.
4 to start it up and set it up to an executable state.

The form description information management unit 62 searches for the location of drawing form description information used when drawing and developing the given data type, as shown in the flowchart of FIG. 32(b).

That is, the position of the drawing form description information on the floppy disk 28a, the page memory 14, and the magnetic disk 27a is used as a pointer of the form information. At this time, if there is drawing format description information on the floppy disk 28a, the page memory 14, or the magnetic disk 27a, the floppy disk 28a is referred to with priority.

In this way, no matter what format the retrieved drawing format description information is determined at the time of registration, the user can arbitrarily change the format and display or print it out.

The drawing form description information varies depending on the type of individual data, but as shown in FIG. 35, for example, it is described as vector information when drawing data is output to a plotter (not shown).

For example, the first line, which is written entirely in character strings, is
It is defined as a pen with a line drawing attribute of red color and line width of 0.
．． 3mm, the second line is defined as the second pen, the line drawing attribute is blue and the line width is 0.3mm, and the third line is defined as the third pen. The line drawing attributes are black and the line width is 2.0 mm, the fourth line is defined as the fourth pen, and the line drawing attributes are:
It is black with a line width of 4.0 mm.

Here, in a normal plotter, the user can select the color and thickness of the line by selecting the pen to be used, but in this device, the pen is not actually driven, so this is not possible with the plotter. As in the case of , when the drawing attributes corresponding to a pen are changed by selecting a pen, drawing style description information is required as a definition of which pen has which drawing attributes. There is.

The drawing module main section 61 inquires of the lower-level individual data interpretation and drawing processing section that has already been activated about the attributes (size, density, drawing direction) of the data that is about to be drawn. The format of the command at this time is, as shown in Figure 36(a), a data pointer,
It consists of a pointer to form information and a format (return).

The pointer of the form information indicates the location of the drawing form description file searched by the drawing module main section 61. The format is return value.

The interpretation drawing processing section 63a1... returns the format information determined by the drawing form management section 82 to the drawing module main section 61 based on the pointer of the form information and the return value. This returns the original size of the data to be drawn.

As a result, the drawing module main section 61 determines the final format based on the returned content and the requested specifications from the higher-level application task, as shown in FIG. 32(C).
It is designed to be drawn as shown in the flowchart.

That is, in the case of automatic drawing, the return value is used to draw as is, but in other cases as well, modeling parameters are determined from the return value and externally designated values.

For example, if the externally designated size is A3 paper size and the internal data is A4 paper size, the value of the modeling parameter is set to a value that should be expanded by f1.

When all the parameters are set as described above, the drawing module main section 61 calls the corresponding interpretation drawing processing section 63a (63b, . . . ) to execute drawing. The format of the command at this time is shown in Figure 36 (
As shown in b), it is composed of data pointers, form information pointers, formats, and modeling parameters.

If you draw in the display memory 15 or page memory 14 according to the above flow, or if code data is stored in the page memory 14 as described above, this area will be occupied and the area for drawing development will be may not be guaranteed.

For example, the total size of the page memory 14 is 4
When it is M bytes, the area is only A3.400DPI,
Since the amount of data is approximately 4M bytes, if the code data is on the page memory 14, it will be A3.400DP I
This means that the image cannot be drawn.

In such a case, temporarily save the code data in the page memory 14'', expand the drawing, and output it to another device.
It is only necessary to store it again on the page memory 14.

This operation will be explained with reference to flowchart 1 shown in FIG. 32(d).

First, an attempt is made to secure an area for drawing and expansion.

If this is not possible, a flow of saving the magnetic disk 27a is entered. Then, the code data on the page memory 14 is once saved on the magnetic disk 27a, and after drawing and development are performed and output processing is performed, it is stored again.

Output processing means, for example, writing to one optical disc,
This means outputting to the printer 25 or transferring to external equipment via LAN or the like.

As a result, the page memory 14 can be used as effectively as possible.

The command format of the drawing module in this case is
The data point in FIG. 34 is the magnetic disk 27.
This indicates the location of the file on a.

On the other hand, when outputting to the printer 25, the size of the output paper is fixed or limited to two or three depending on the size of the cassette installed in the printer 25. Therefore, even if a request is made to render a large-sized image, the output size is limited to the size of the paper on which it is mounted. For this reason,
Even if you do not save on the magnetic disk 27a,
In some cases, it may be sufficient to reserve the page memory 14 based on the paper size that is mounted. In this case, the magnetic disk 27a
The processing overhead caused by saving can be reduced. The operation is shown in the flowchart of FIG. 32(e).

By combining the case where such saving is not performed and the above-mentioned saving, it is possible to use the page memory 14 more efficiently.

Also, the process of drawing overlay with the format screen will be explained. As mentioned in the FD registration section, when registering, code data is not registered by drawing it on a blank sheet of paper, but in a certain format, such as a table on which drawing numbers can be written, or a table with predetermined ruled lines. You can register and print out by drawing on the mount paper.

Here, this is achieved by a method in which when a command extension is specified from a higher-level application, drawing format description information describing the format is referenced, and drawing is performed in advance before the image data is developed.

In this case, drawing in a certain format may require a processing module different from the original interpretation and drawing processing of the code data, but it is now done by sequentially calling and executing lower-level modules. There is.

Next, the processing at the time of FD registration for the drawing processing function not incorporated in this device will be explained. In other words, there are a large number of types of data, and the apparatus may not yet have a drawing processing function that corresponds to the type of code data that the user wants to register on the optical disc 19.

In this case, specify the data type as "Other",
There are some methods that respecify the type of data once the drawing processing function is installed, but it is a very troublesome task to modify the type flag in the subheader section of the code data that has already been recorded on one optical disk. It has become. Also,
If a write-once type optical disc 19 is used, correction is impossible and new code data must be re-recorded.

Therefore, in anticipation of the future, we set a reservation number as the data type, and when registering code data before the drawing processing function is built in, we recommend specifying the reservation number as the data type. do.

For example, when the "next candidate" of the data type is specified (see Figure 37), "Reservation 1", "Reservation 21", "Reservation 3", etc.
” and “Other” are displayed.

Then, when the drawing processing function is installed, by correlating the reservation number with the drawing processing function, the process of correcting the type flag in the subheader section on the optical disk 19 can be omitted.

As mentioned above, if the rendering expansion of the data searched and displayed during a search is incorrect, the expansion format is changed and a different rendering expansion is displayed on the CRT display device. Even when code data such as read document data, drawing data, etc. is registered in an optical disk and its drawing development format is incorrect, the code data can be correctly drawn and developed and displayed on a CRT display device.

In the above embodiment, the expansion format is one in which code data is converted into image data, but it may be one in which image data is converted into code data.

[Effects of the Invention] As detailed above, according to the present invention, even if data is stored in an incorrect data expansion format when retrieving data from a storage medium, it is possible to correctly input the data to the display device. An electronic filing device capable of displaying information can be provided.
