Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an electronic filing device that performs data processing 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 IN planes (consisting of vector code data) created using IDEED DESIGN). Document data created with these word processors, personal computers, and drawing data created with CAD are either stored on floppy disks (magnetic storage media) or are difficult to attach with 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 documents 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 a floppy disk.

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 poor efficiency.

Therefore, an electronic filing device has been proposed that can handle and manage document data and drawing data stored on a floppy disk in the same way as paper drawings (Japanese Patent Application No. 1982-23OO20).

However, in such a device, when outputting document data, drawing data, etc. retrieved from an optical disk to a magnetic storage medium, or when registering document data, drawing data, etc. read from a magnetic storage medium to an optical disk, It is necessary to check the contents of the data.

Therefore, as a means for checking this data, a drawing display process is performed on the data.

However, if the data can only be processed by drawing, nothing can be displayed and the user cannot see the contents of the data.
There was a problem that it was not possible to confirm the

(Problem to be Solved by the Invention) As mentioned above, it is possible to prevent the disadvantage that it may not be possible to confirm the data to be registered when registering to an optical recording medium or a magnetic recording medium. An object of the present invention is to provide an electronic filing device that can reliably display confirmation of data to be registered when registering on an optical recording medium or a magnetic storage medium.

A conversion means for converting into image data, a display means for displaying the image data supplied from the conversion means, and a display means for displaying the code data read by the reading means when the conversion is not performed by the conversion means. It is composed of processing means for displaying.

(Operation) This invention reads code data from a storage medium in which the code data is stored by a reading means, converts the read code data into image data by a converting means, and displays the converted image data. If the conversion means does not perform the conversion, the code data read by the reading means is displayed on the display means.

The scanner 20 is, for example, a two-dimensional scanning device that scans an original (document) two-dimensionally with laser beam light to obtain an electrical signal corresponding to image data on the original.

The optical disk device 22 sequentially stores image data read by the scanner 20 or code data read by the magnetic disk device 28 on one optical disk (storage medium).

The keyboard 23 is used to input code information stored on the optical disc 19, a unique search code corresponding to image data, various operation commands, and the like. The CRT display device 24 is an output device, such as a cathode ray tube display device, which is a display device, and displays image data read by the scanner 20, code data read from the magnetic disk 28, or code data read from the optical disk device 22. , or display image data. The CRT display device 24 is capable of displaying four documents simultaneously using a maximum of four windows. For example, four pieces of document data are displayed vertically.

A search code input using the keyboard 23, one piece of code data corresponding to this search code, a storage address on the optical disk 19 where image data is stored, data size, a flag identifying whether code data or image data, etc. Search data (management data) consisting of is stored. Further, the code data and image data for each case are stored in the search data area of the optical disc 19.

The magnetic disk device 28 is, for example, a 5.25 inch, 3
．． This is a floppy disk device that uses a 5-inch floppy disk 28a, and code data files such as text files (document data) created with a word processor (not shown) and CAD drawing files (drawing data) created with a personal computer (not shown) can be stored on the floppy disk. 28a.

The floppy disk 28a can be formatted under various OS (operating systems).

The mouse 29 is a pointing device, for example C
RT display device 24" move the second cursor up and down,
By moving the cursor arbitrarily in the left and right direction and giving instructions at the desired position, the display contents (for example, various modes, editing images, cut and paste ranges, icons, etc.) at which the cursor is located are selected. .

Next, how image data and code data are managed in a unified manner will be explained from the perspective 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 a cabinet, and up to about 30,000 documents can be registered in a 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 file data on one floppy disk, or any of these three types of data or merged data.

As a result, for example, in one document, a group of source files (code data) of a predetermined program as one 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 executed by the image input/output processing module 13.
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 13g1, 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 50a1, an FDD power processing module 50b, an FDD search processing module 50c, an FD source processing module 5od1, 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 FDD recording screen, including the total number of files, file name for each file, file size, file date, and subdirectories of files. 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, after calling the display control module 13e and confirming the input image data on the CRT display device 24, 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 MDD management module 13f is called, and the address where the image data on the optical disk 19 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 process is the same 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 enters the search expression (search key, keyword for search), the MDD
Search processing is performed through the management module 13f, 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 one optical disc.

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". becomes.

The data header section is composed 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. These files are collectively managed using a document management application, with each related file being treated 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 vine section. Types of subheaders include image data header, FD
- There are three types: bulk data header and file data header.

As shown in Figure 7, the image data header includes subheader length (2 by I), type flag (2 by 1), data address (4 bytes), and data size (4 bytes).
, compression format (2 bytes, MH.

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

300 dpi, etc.), image size (4 by l-, A4,
B4, A3, etc.), and an option area (O 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 D1, 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 of these data headers are flags indicating which size floppy disk 28a the data comes from; for example, 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 whether it is 1800 bpi or 6250 bpi.

The OS flags in these data headers indicate the type of O8, such as O3I, which runs CADI, O82, which runs CAD2, and OSWp, which runs word processors.

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 in the OS flag.

The main memory 13 is also provided with a module management data storage area 1311, a header management data storage area 13°, and a data header section 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 13 corresponds to the number of currently selected modules, the recording address and size in the main memory 13 (data header storage area 139) where the data of the data header part is stored. It is meant to be remembered.

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
or selected as an 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.

To move to the desired directory, the operator can directly enter the directory name in the "Directory Name" field using the keyboard 23, or use the "<" or "<" symbol in the file name list.
The directory surrounded by ">" is selected using the keyboard 2B or the mouse 29.

"-Target" is for specifying a wild card for the file name to be displayed in the file name list.For example, "*, *j" means that all files in the current directory will be displayed. Here, rc*
, *J from the keyboard 23, only file names starting with "C" or a list of file names will be displayed.

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

In the file name list, there is a current file indicated by a highlighted frame, and on the right side of the file name list are "△" and "".
Or use the function key "F5; Previous file", "
This current file can be moved by instructing "F6; Next file". Figure 10 shows the state in which the - soil file is selected, then "F6; Next file"
This is the screen with the command 5 times, for example, rcON
The file IO, Cl is selected as the current file.

When checking the contents of the current file, you can instruct "F3; Display contents" to display the contents in the method specified by "Type of data." As shown in FIG. 11, this content display shows a file called rcON IO, Cl with 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 1.3g 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 correctly display the contents by respecifying the data type.

Also, on the content display screen shown in FIG. 12, rF4
, DUMP display" allows the raw code data of the current file to be displayed in hexadecimal representation (DUMP display) as shown in FIG.

That is, the code data is converted into a two-digit hexadecimer 30 - Ruco-1' (0000,0001,...,1]11
(expressed as 0.1, . . . , F), and the address on the file is displayed sequentially in 16-height increments starting from the beginning. Also, each 8-bit data is ASCII (
In the case of data corresponding to ASCII) codes, the corresponding alphanumeric characters are also displayed on the right edge.

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

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 "△" 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 ONIO 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, 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 13a. Output to.

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 or not, 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 data on the optical disk 19 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.

Thereafter, the filing processing module 1.3a again calls the FDR/W processing module 13c 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 disc 19'2.

Also, if the operator inputs termination, FDR/W
The termination status is supplied to the processing module 13c.

If the operator makes another input, another processing module is called and the process shifts to waiting for input from the operator again.

In addition, if the result of the determination is the batch FD registration mode, if the operator does not input stop and there is a selected file, the FD input processing module 50b is called and the FDR
/W processing module 13c has floppy disk 28a
It outputs the start address and data length supplied from 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, the FD input processing module 50b is configured as shown in FIG.
), a file selected from the file name list table is searched, and file data corresponding to the searched file is read from the floppy disk 28a to the page memory 14. If the operator has set the registration mode to code data,
A main header and a code data header for code data are set, and if image data is set, the drawing processing module 13g is called to convert the code data to image data (image data). At this time, code data, the type of data specified by the operator, the imaging format, and drawing form file data (described later) are outputted to the drawing processing module 13g as the input parameter register 31.

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

Next, opercy. If the user has set automatic title addition to "Yes", 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 14 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 "4; 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,
Return the data type to the original and draw processing module 13g
is displayed as shown in FIG. 12. Then, when the operator inputs "F9;Confirm", this display is erased and the display returns to the one shown in FIG. 11.

In addition, when "F4; file name list display j" is input, the device, directory, and file list specified by the operator are searched for on the floppy disk 28a, 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 input, the current file within the part of the file name 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. [F8. If "All Files Selection Cancellation" is input, the all selection flag in the file name list table is set to OFF, and the wire mesh dot display within a part of the file name on the FD registration amount surface is erased.

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 j, "-
If "view target" is entered, update each setting. After performing these processes, the display returns to the one shown in FIG. 11.

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 19, 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" in the FD registration amount surface to "imaging data", the floppy disk 2
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 disk 9. 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,
This prevents the time it takes to search and display the code data in the optical disk 19, and reduces the search time. That is, by recording the image data on 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 10 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. Also, "Code 10 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, which 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 =42- "designation" means "designation" set by the operator. The images are created according to the "size", "specified density", and "specified 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 outputted to the drawing processing module 13g together with the code data and the drawing form file data, and is made into an image there.The details of this information are processed by the drawing processing module 13g, which will be described later.

Next, the search process will be explained with reference to the flowcharts shown in FIGS. 17(a) and 17(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 will be 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. 18 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 contents, and attributes already registered on the optical disk 19 cannot be changed. 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, the information (name, size, update date and time) of the files that meet the conditions set for viewing are read from among the files in the buoy library set as the output optical directory, 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 uses the mouse 29 to instruct to change the output optical device, 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 optical directory is designated 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, direct instructions in the file name display area 70 can be made by selecting the file name and the directory being viewed using the mouse 29.
After specifying the file name and moving the cursor, either specify the same directory again with the mouse 29, or use the ``previous file j key'' and ``next file'' key on the keyboard 23 to move the cursor to the directory you are viewing. After moving , you can specify the directory by pressing the ``select'' key.

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

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 displayed for confirmation using the content 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", "-pickup 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 a part of the function key is instructed to "execute", 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 floppy disk 28a after output
The above file name can be changed by pressing keyboard 23 on the FD output screen.
It can be entered from. 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-raster 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 due to a text file, etc., use the mouse 29 to indicate the upward/downward arrow icon on the output target content display screen, or use the upward/downward arrow icon on the keyboard 29. By pressing the arrow keys, you can move to the previous page/in the same output target file.
It is now possible to move to the next page, that is, update the output target content display screen. Further, if "cancel" is instructed during content display, the image development process is 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.

Further, when "confirm" is instructed with the mouse 29 or the keyboard 23 on the output target content display screen, the display of the output target content ends.

When the function key ``display part 1 contents'' is specified, 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 20. . There are two types of this display: vector rask conversion expansion display and dump display. These two selections can be made by pressing the function key F8 (D
UMP) 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 disc 19.

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 20. displayed on the screen.

Furthermore, if all the contents cannot be displayed on one screen due to a text file, etc., the screen can be updated 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 the mouse 29 or keyboard 23 on the content display screen shown in FIG. 20, the file name list in the file name display area on the FD output screen is displayed. In this order, 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 (size: density: lower row) of the contents display screen 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.

If you specify "File name - list display", FD output screen"
2. According to the device, directory, and target for output light set in 2, the output light floppy disk 2
Necessary information is read from 8a, and a list of file names of the corresponding files 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 "-extraction power" for a part of the function key, the batch output property sheet is displayed as shown in Figure 21, and you can select either 1 document - limited 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 following the one document extraction power or the all document extraction power, the bulk output property sheet is closed and the previous page of the designated document is sequentially output to the floppy disk 28a. Then, when the output processing of the previous page of the document to be outputted as the FD ratio is completed, the screen returns to the FD output screen shown in FIG. 18. 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 in FIG. The FD output processing up to this point is valid. In addition, 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 attributes will be displayed. information i.e. 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 the optical disc 19 is set in 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 the optical disk 19 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 instructed to display the output target content, 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 the FD output processing module 50d is instructed to output an FD ratio 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
4) Output and save the code data to be output held in 2 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 large FD input described above.

Next, regarding the specific method of drawing code data,
This will be explained using FIGS. 22(a) to 22(e).

That is, the drawing of the court data is performed by the deep 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 13g, as shown in FIG.
It is composed of a drawing module main section 61 and an individual data interpretation drawing processing section 62.

The drawing module main unit 6] includes an image input/output processing module 13b as a second-rank application task;
Based on the request from the FDR/W processing module 13C1 display control module 13e, it activates the lower-level interpretation and drawing processing units 63a, etc. necessary for drawing the data, and sets the drawing size and format. It also 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 section 73 calculates and sets parameters for arbitrarily setting the size and direction during image development.

The individual drawing processing starting section 74 starts up the lower-level individual data interpretation drawing processing section 62 according to the type of data given from the application.

As shown in FIG. 24, 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 specification drawing (drawing by specifying the format from the outside), (3) Modeling specification drawing (drawing by specifying the format from the outside) There are three modes (drawing by specifying modeling parameters).

The pointer to the data is whether the data to be drawn is in the page memory 14, or if it is, a pointer on the page memory 14, or if it is on a file, the 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 63a, . . . should be activated.

The drawing location specifies whether to draw on the page memory 14 or the display memory 15.

The form specifies whether to draw on a blank sheet of paper or on a format sheet 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 clean formatting specifications or modeling specifications.

Modeling parameters are also specified at the time of modeling specification drawing. Here, regarding the format and modeling parameters, if they 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.

In other words, when code data is first drawn from the page memory 14 to the display memory 15, such as by reading from one optical disk or manually from the floppy disk 28a, it is not possible to determine the size of this data until it is drawn. There are times when 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 area to be drawn have already been defined, and the drawing process is performed so that the area is appropriately placed there. This is format-specific drawing.

In addition, modeling-designated drawing is a drawing process that performs drawing processing 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 63a, . . . 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 unit 81 receives commands from the drawing module main units 6.

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 development 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 section 61 causes the interpretation drawing processing section 63a (63b, . . . ) corresponding to the data type to be activated by the individual drawing processing starting section 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 type of data given, as shown in the flowchart of FIG. 22(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 the floppy disk 28a''2, the page memory 4''2, and the magnetic disk 27a''2 each have drawing format description information, the floppy disk 28a is referred to preferentially.

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 differs depending on the type of individual data, but as shown in FIG. 25, 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 attribute is black with a line width of 2.0 mm, and the fourth line is defined as the fourth pen, and the line drawing attribute is [7, black with a line width of 4.0 mm. It becomes.

Here, with a normal plotter, the user can choose the color and thickness of the line by selecting the pen to be used, or with this device, since the pen is not actually driven, 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 unit 6] queries the lower-level individual data interpretation and drawing processing unit 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 26(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 units 63a, . . . return the format information determined by the drawing form management unit 82 to the drawing module main unit 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 upper application task, and then determines the final format as shown in FIG. 22(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 external specified size is A3 paper size and the internal data is A4 paper size, the value of the modeling parameter is set to a value at which (i-fold enlargement should be performed).

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 composed of a data pointer, a form information pointer, a format, and modeling parameters, as shown in FIG. 26(b).

According to the above flow, drawing is performed in the display memory 15 and page memory 4. However, as mentioned above, if code data is stored in the page memory 14, this area is occupied and The area may not be secured.

For example, when the size of the entire page memory 14 is 4M bytes, the area of A3.4QQDP I is approximately 4MB.
Since the amount of data is equivalent to M bytes, if the code data is in the page memory 14'', it will not be possible to draw an A3.400 DPI image.

In such a case, the code data on the page memory 14 may be temporarily saved, and the data that has been rendered and expanded and output to others may be stored again on the page memory 14.

This operation will be explained with reference to flowchart 1 shown in FIG. 22 ('cl).

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

If this is not possible, a flow of saving the magnetic disk 27a is entered. Then, the code data in the page memory 14'' is temporarily saved on the magnetic disk 27a, and
After rendering is performed and output processing is performed, it is stored again.

Output processing means, for example, writing to the optical disk 19,
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. 24 is the magnetic disk 27.
This indicates the location of the file on a.

On the other hand, when outputting to the printer 25, = 7]
- 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 there is a request for rendering processing of a large-sized image, the output size is limited to the size of the paper on which it is mounted. Therefore, there may be cases where it is sufficient to reserve the page memory 14 for the paper size that has been mounted, without having to save on the magnetic disk 27a. In this case, it is possible to reduce processing overload due to saving on the magnetic disk 27a. The operation is shown in the flowchart of FIG. 22(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 or print out by drawing on the mount provided.

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 expanded.

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

As mentioned above, read from a floppy disk,
Alternatively, when checking the contents of code data such as drawing data retrieved from an optical disk, if the data cannot be displayed graphically, the dump data can be displayed as is. 6 to 73- Also, when checking the contents of code data such as drawing data read from a floppy disk or retrieved from an optical disk, it is possible to check the contents by displaying the contents drawn or expanded. Dump data as raw code data can be selectively and arbitrarily displayed.

[Effects of the Invention] As detailed above, the present invention provides an electronic file that can reliably display confirmation of data to be registered when registering on an optical recording medium or magnetic recording medium. Link equipment can be provided.
