[Detailed Description of the Invention] [Industrial Application Field] The present invention is an information file device, that is, a large-capacity storage medium such as an optical disk, which is configured to register image information such as documents and drawings as file information and read it out at any time. The present invention relates to a revision method such as replacing, adding, or inserting a page of file information once registered in a registered device.

[Prior art]

2. Description of the Related Art Information file devices have been put into practical use that are configured to register image information such as documents and drawings as file information in a large-capacity storage medium such as an optical disk, and to read the information at any time.

FIG. 1 is a block diagram showing the general configuration of such a conventional information file device. A document to be registered in the disk device 9 is read by the scanner l, and this image information is recorded in the image memory 2.1. let a. Then, the image information recorded in the image memory 2 is transferred to the display memory 3, so that the image information written in the image memory 2 is transferred to the display device CI? displayed on the T display 5. After confirming the display on the CRT display 5, the operator inputs a keyword or the like as information for specifying this image information using the keyboard 5, and instructs the registration of the image information.

As a result, the image information is compressed in amount by the codec circuit 7, transferred to the optical disc device 9, and written on the optical disc.

At this time, information on the storage location of the image information on the optical disk is stored in a search information storage device such as a RAM in the system control circuit 6. Furthermore, data is stored in the search information storage device as search information, with the storage location address of the storage location information in the search information storage device and information specifying the file information inputted by the operator as a set.

FIG. 2 is a schematic diagram showing an example of the data structure of search information stored in the search information storage device in the system control circuit 6 described above.

The conversion table area Ml is an area for storing a fixed length conversion table that uses several bytes for one piece of file information. The details of the conversion table are shown in Figure 3 (al), file attribute data FCD indicating file attributes,
Page number data PAGE, which indicates the number of pages in the file;
It consists of a file name index FNIDX that indicates an index for storing a file name, an optical disk information index 0DIDX that stores a storage position address between optical disk information areas of storage position information of the first page of a file in the optical disk device 9, and the like. The file attribute data FCD indicates information such as deletion and grade of the file. The page number data PAGE indicates the number of pages registered in one file, that is, the number of manuscript sheets. The file name index FNIDX indicates the start address of the file name of the file. Optical disk information index 0DID
X stores an address for referring to the optical disc information area M4.

The file name area M2 stores the name given to the file.

The date on which the file was registered is stored between the registration date areas.

The optical disk information area M4 stores optical disk information, which is information such as storage position information on the optical disk 9 for each -page (-page corresponds to one sheet of image information) of one file information. ing. Figure 3 (bl indicates a data block for storing optical disc information for one page of the optical disc information area M4, and the data block shown in Figure 3 (bl) is in the optical disc information area M4. A number of data blocks corresponding to the number of pages of file information are stored consecutively.This data block is made up of several bytes as a unit, and page attribute data pco indicating the attributes of the page is stored, and page attribute data pco indicating the attributes of the page is written on the optical disk 9. The trunk address TRA is composed of a track address TRA indicating the stored address (storage location information), etc., and if the page is stored across multiple tracks (storage areas) of the optical disk 9, the trunk address TRA is TR1. ,T
There are multiple numbers such as R2...

The page attribute data PCB includes the document size in data areas BO and Bl, the resolution in data areas B2 and B3, and the compression of image information in data areas B4 and B5, as shown in Figure 3 (C1 details). Each encoding method is memorized.

The keyword area M5 stores keywords registered by the operator.

Next, a method of reading file information registered in such an information file device will be explained. An operator operates the keyboard 5 to input information such as a keyword to specify a page from which desired file information is to be read. According to this, the system control circuit 6 converts the conversion table area M1.
is searched to find the corresponding file information conversion table, its contents are read, and the page attribute data PCD of the page to be read in the optical disc information area M4 is read according to the optical disc information index 0DIDX. When this page attribute data PCD is found, it is possible to read out the stored track address TRA. Therefore, if this track address TRA is given to the optical disk device 9, the page of the target file can be read. The image information is read from the optical disc, and is decoded by the codec circuit 7 to obtain original image information. Therefore, if this original image information is written into the image memory 2 and the display memory 3, it will be displayed on the CRT display 5, and it will also be possible to make a hard copy using the printer 8.

Note that if the file information to be read is composed of multiple pages, the optical disc information of the first page is read from between the optical disc information areas, so that the optical disc information of the first page and subsequent pages continues to be read. Each page is read from the optical disk by reading the information and reading the storage location information stored in each page.

[Problem that the invention seeks to solve]

By the way, in such conventional information file devices, when a certain page of already registered file information is no longer needed, file revision processing such as replacing that page with another document is not possible with optical technology. This is possible if you wish to rewrite the entire contents of the disk information area. The reason for this is that the optical disc information of each page of the same file information is continuously stored between optical disc information areas when the file information is registered, so that when the optical disc information of the first page is read, However, if other file information is registered next, the optical disk information of each page will be stored following the optical disk information of the previously registered file information. Therefore, even if new image information is stored on an optical disc as a -page of already registered file information (file information subject to revision), that optical disc information will be stored at the end of other file information stored at that point. This is because the new page cannot be associated with the optical disk information of each page that has already been registered in the file information to be revised because the new page is stored next to the optical disk information of the page.

However, there is a problem in that it takes a long time to rewrite the entire contents stored in the optical disk information area.

The present invention was made in view of these circumstances, and
The object of the present invention is to provide an information file device that can revise any page of file information composed of a plurality of pages by replacing, adding, or adding one page.

[Means for solving problems]

In the present invention, each page of file information is replaced.

If there is a revision such as an addition or insertion, the storage location information on the optical disk of that page is newly stored in the search information storage device, and the optical disk of the page targeted for replacement, addition, or insertion is stored. By storing the storage location address in the search information storage device where the storage location information on the optical disk of the newly added page is stored instead of the storage location information above, the image information can be stored. At the time of reading, after this is read out, image information is read out from the optical disk in accordance with this.

The present invention stores file information in a file information storage medium, stores storage location information of each page in a search information storage device, and stores the storage location address of the storage location information in the search information storage device and its file information. and specifying information is stored in the search information storage device, and by inputting information specifying the file information to be read, the search information of the file information is read from the search information storage device, A page by adding a page of an information file device in which storage location information is read from the search information storage device in accordance with the read search information, and each page of file information is read from the file information storage medium in accordance with this.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on drawings showing embodiments thereof. Note that FIG. 4 is a schematic diagram showing the storage state of the conversion table as search information and optical disk information as storage location information in the search information storage device of the information file device according to the method of the present invention, and FIG. 5 is for explaining the operation. This is a flowchart.

Now, among the multiple pages that make up a certain file information, the page that should be deleted due to replacement is page 1,
Image information newly added to the file information instead of page 1 is called page 2.

First, the operator obtains one page of image information as the image information of the newly added page 2, for example, by reading the document with the scanner 1, or by reading out already registered image information from the optical disc device W9.

Next, the operator selects page l to be replaced (the conversion table for file information that includes page 1 is n in Figure 4).
In order to search for the page 1 stored in the conversion table area M1 indicated by , information such as a keyword specifying the page 1 is inputted using the keyboard 5. and,
When the operator instructs page replacement, the image information of the newly added page 2 is compressed and encoded by the codec circuit 7, and is written and stored on an optical disk by the optical disk device 9.

At this time, optical disk information (page attribute data PCD) which is storage position information on the optical disk regarding page 2
and track address TRA) is the optical disk information (track address TRA) of the last page of the last file information (the conversion table is stored in the position shown by l in FIG. 4) among the already registered file information. 4), that is, in the data block located at position i.

Next, since the optical disk information index 0OIOX of the search information for page l indicates the storage position of the storage location information for page l, the system control circuit 6 stores the optical disk information data for page 1 between the optical disk information areas. The block is read out, and the system control circuit 6 sets a flag indicating that the page has been replaced in the data area B6 of the page attribute data PcO of the data block of the optical disk information of the read page 1. Further, the system control circuit 6 stores the search information 1.0 of the page attribute data PCD of the page 2 in the track address TRA of the page.
Sets the address of a storage location on the device.

The data block of the optical disc information of page l thus rewritten is stored at position n2 of the search information storage device indicated by the optical disc information index oorox of page 1. This completes the replacement process for any page of file information.

Next, reading of page 2 replaced as described above will be explained.

When the operator inputs information specifying the file information by operating the keyboard 5 and instructs to read page 2 of the file information in which page 1 has been replaced with page 2, the system control circuit 6 reads the input file information. The search information storage device is searched according to the specified information, and a conversion table of file information containing page 2 (n
(stored in the position of the conversion table area Ml shown in ) is searched for. The system control circuit 6 reads out the data block stored at position n2 of the optical disk information of page l according to the conversion table data stored at position n in the old conversion table area. Then, it is checked whether a flag instructing page replacement is set in the data area B6 of the page attribute data PCD.

Now, the page replacement flag is set in data area B6)
If so, the trunk address TRA of the data block stored in the position n2 contains the search information of the page attribute data PCD of page 2 added in place of the replaced page 1, on the Q device. Since the storage position, specifically the start address of the data block stored at position i, is stored, the system control circuit 6 stores the trunk address TRA of the data block stored at position i. It becomes possible to read the contents, that is, the optical disc information of page 2. As a result, the system control circuit 6 reads the image information of page 2 from the optical disk device 9 and stores it in the image memory.
