[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, in which one page of image information such as a document or drawing is registered as file information as a page. The present invention relates to a method for registering multiple pages in a device configured to read data at any time, which allows multiple pages to be registered at any time in one file information.

[Prior art]

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

FIG. 1 is a block diagram showing the general configuration of such an information file device, in which, for example, one page of file information is written and read from an optical disk as a large-capacity storage medium. A document to be registered in an optical disk device 9 is read by a scanner 1, and this image information is stored in an image memory 2. The image information stored in the image memory 2 is then transferred to the display memory 3 and displayed on a CRT display 5, which is a display device. 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.

Through such processing, 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, the storage location information of the image information on the optical disk and the information (keywords, etc.) specifying the file information entered manually by the operator are mutually associated search information in the system control circuit 6.
The information is stored in the search information file 10, which is a search information storage device connected to the search information file 10.

FIG. 2 is a schematic diagram showing an example of the data structure of the above-mentioned search information file 10, including a conversion table area Ml, a file name area M2. Registration date field M3. Keyword area M
4 and an optical disc information area.

In the conversion table area old, an area is secured that can store, for example, up to N fixed-length conversion tables that use several bytes for one page of one file information.

The file name area M2 stores names given to each piece of file information.

The registration date area M3 stores the date when each piece of file information was registered.

The keyword area M4 stores keywords registered by the operator, that is, information attached to each piece of file information to specify it.

The optical disc information area M5 contains each page of each file information (-page corresponds to one piece of image information).
Storage position information on each optical disk 9 is stored.

The conversion table for each page stored in the conversion table area M1 includes the conversion table for that page.

According to the address of the storage position in the information area M5, storage position information on the optical disc of each page of file information to be read is read from the optical disc information area M5.

When this storage location information is given to the optical disk device 9, the image information of each page of the target information file is read from the optical disk, and this is decoded by the codec circuit 7 to obtain original image information. Therefore, if this original image information is written to the image memory 2 and display memory 3, CR
It is displayed on the T-display 5, and can also be printed as a hard copy using the printer 8.

[Problem that the invention seeks to solve]

By the way, in such conventional information file devices, when registering multiple pages as one file information, all of the multiple pages must be registered at the same time when registering the file information for the first time. . In other words, when registering file information consisting of multiple pages, the search information for a series of pages (the above-mentioned conversion table) must be stored consecutively in the conversion table area of the search information file, which is the search information storage device. For example, this is because the search information for consecutive pages of the same file information is not read out. This is done by preparing the configuration and capacity of the search information storage area of the search information storage device for the number of pages (number of image information) that can be registered in the information file device, and sequentially storing the search information of each page. This is because the configuration is such that the

Therefore, in conventional devices of this type, there was a problem in that if one file information was registered and then another file information was registered, it was difficult to add a page to the previously registered file information.

In addition, even if one information file device is configured to allow registration from multiple terminal input devices and file information is registered from the multiple terminal input devices at the same time, multiple pages may be registered for the same file information. A situation arises in which it is not possible to register.

The present invention was made in view of these circumstances, and
The purpose of the present invention is to provide a method for registering multiple pages in an information file device, which enables additional registration of pages to already registered file information at any time.

[Means for solving problems]

In the present invention, a conversion table (hereinafter referred to as first page conversion table) as search information for the first page of each file information is configured as shown in FIG. That is, the conversion table for the first page of each file information is the file control data T1. File name block address data T2. It consists of optical disk trunk block address data T3 and page number data T4.

The file control data T1 contains information such as whether the file information to which the page belongs is valid or has been deleted, and the file name block address data T2 contains the file name attached to the file information to which the page belongs. The address of the stored file name area M2 is the address of the optical disk information area M5, which is the first storage area where the storage position information on the optical disk of that page is stored in the optical disk track block address data T3. However, the page number data T4 stores the total number of pages of the file information to which the page belongs.

As shown in Figure 3 (al), this first page conversion table is stored in the search information storage device (in Figure 1, the search information file).
The conversion table area M1, which is the second storage area, is +11. (21, (31...) are stored in the order in which each file information is registered.

On the other hand, a conversion table (hereinafter referred to as a multi-page conversion table) as search information for each of a plurality of pages subsequent to the second page of the file information has a configuration as shown in FIG. 3(C). That is, the conversion table for each of the plurality of pages subsequent to the second page of each file information is the multi-page file control data T11. File number address data 12. It consists of optical disc track block address data T3 and page number data T14 similar to the first page conversion table.

The multi-page file control data Tll of this multi-page conversion table contains data indicating that the page of this conversion table is the second or subsequent page, and the file number address data T12 specifies the file information to which the page belongs. The optical disk trunk block address data T3 contains the address of the optical disk information area M5 where the storage position information of that page on the optical disk is stored, as in the case of the first page conversion table described above. , page number data T1
4 stores page number data in the file information to which the page belongs.

This multi-page conversion table is stored in a search information storage device (in FIG. 1, a search information file) as shown in FIG. 3(a).
In the conversion table area M1, which is the second storage area of
The pages are stored in the order of registration, such as N-1), (N-2), and so on.

Therefore, in the present invention, when multiple pages of file information are registered in the information file device shown in FIG. The position information is stored in the optical disk information area M5 of the search information file 10, which is a search information storage device. The address of each storage location for the first page is shown in Figure 3(b).
It is stored in the optical disk trunk block address data 3 of the first page conversion table shown in FIG.
Each subsequent page is stored in the optical disk track block address data T3 of the multi-page conversion table shown in FIG. The total number of pages of the file information is stored in the page number data T4 of the first page conversion table. In addition, the multi-page file control key ITII of each page of the multi-page conversion table contains data indicating that the page is a plurality of pages, and the file number address data T12 contains a number specifying the file information to which the page belongs. T14 stores data indicating the page number of the file information to which the page belongs.

The above explanation applies not only when registering file information consisting of multiple pages sequentially starting from the first page, but also when registering additional pages to already registered file information. If you register the page with the keyword of the file information that has already been registered and the page that is continuous to the last page of the file information,
Only the processing for the second and subsequent pages of the file information described above is performed, and the pages are registered in a state where they are added to the already registered file information.

Therefore, when reading multiple pages of file information registered in the information file device in this way, when a keyword is input as information for specifying the file information to be read, first the conversion table area M1 is displayed at its starting address. The first page conversion table corresponding to the input keyword is read out, and the data of the optical disk trunk block address data T3, that is, the optical disk that is the file information storage medium of the first page of the file information is read. The address of the optical disc information area M5 where the above storage position information is stored is read out.

In addition, since the existence of the second page and subsequent pages is known from the file control data T1, the conversion table area M1 is searched in order from the last address to the first address, and the data of the number that specifies the file information is searched as the file number. The multi-page conversion table stored in the address data table 12 is searched, and the data stored in the optical disk track block address data T3 and page number data T14 is read out. As a result, the address in the optical disk information area M5 of the storage position information on the file information storage medium of which page of the file information is read out. Therefore, if the storage location information stored at this address in the optical disc information area M5 is given to the optical disc device 9, each page after the second page of the file information to be read will be read from the optical disc which is the file information storage medium. Read out sequentially.

The present invention stores one piece of image information as one page of file information in a file information storage medium, and stores storage position information of each page in the file information storage medium in a first area of a search information storage device. and a second area of the search information storage device that stores search information consisting of the address of each storage location in the first area and information for specifying each storage location for the number of registrable pages. Let me remember,
By inputting information specifying file information to be read, search information for each page of the file information is read from the second area of the search information storage device, and according to this search information, the first area of the search information storage device is In a multiple page registration method of registering a plurality of pages in one file information of an information file device in which storage location information is read from an area of the file information storage medium and each page of file information is read from the file information storage medium according to the storage location information. , information on the number of pages of each file information is stored in the search information of the first page of each file information, and each search information is stored in the second page of each file information.
The area is stored sequentially from the beginning, and information indicating that multiple pages are registered, information specifying the file information to which the page belongs, and page number information are stored in each page from the second page of each file information. When information specifying file information to be read is input, each search information is stored sequentially from the end to the beginning of the second area, and the search information of the first page of the file information is input. is searched and read from the beginning of the second area of the search information storage device, and the search information of each page after the second page is searched from the end of the second area of the search information storage device toward the beginning. reading the storage location information of each page from the first area of the search information storage device according to each read search information, and reading each page from the file information storage medium according to the read storage location information. It is characterized by giving out.

[Effect]

In the present invention, it is possible to add and register pages to already registered file information at any time, and to register multiple pages of one file information.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments thereof.

Now, when registering file information consisting of a plurality of pages in the information file device shown in FIG. This image information is once stored in the image memory 2, then transferred to the display memory 3, and displayed on the CRT display 4, which is a display device.

Next, the operator enters the keyword, file name, registration date, etc. that is information for specifying this file information, and the fact that the image information currently stored in the image memory 2 is the first page of the file information using the keyboard. 5, the system control circuit 6 transfers the image information stored in the image memory 2 to the codec circuit 7, compresses and encodes it, and provides it to the optical disk device 9 to read the file information. It is stored on the optical disk as one page.

At this time, the storage position information on the optical disk of the image information is given from the optical disk device 9 to the system control circuit 6, so the system control circuit 6 stores this in the optical disk information area M5 of the search information file IO. Then, the system control circuit 6 converts the address of the storage location in the optical disk information area M5 of the search information file IO of the storage location information of the first page into the optical disk trunk block of the first page conversion table as shown in FIG. 3 (C1). This first page conversion table contains data indicating that the file control data T1 is valid file information, and the file name block address data T2 contains the file name of the file information. The system control circuit 6 stores the address of the stored file name area M2 and "1" as an initial value in the page number disk T4.

Next, the operator causes the scanner 1 to read the original image information of the second page of this file information, and inputs by operating the keyboard 5 that it is the second page of the same file information, this image information is The system control circuit 6 stores the second page on the optical disk in the same manner as the first page described above, and the storage location information on the optical disk for the second page is stored in the optical disk information area M5 of the search information file 10. be done. The system control circuit 6
3 (C
1 is stored in the optical disk track block address data T3 of the multi-page conversion table shown in FIG. T14 stores number data specifying the file information to which the page belongs, and page number data T14 stores the page number data of the page. In addition, the system control circuit 6 performs the process of registering this second page, and at the same time adds +1 to the page number data stored in the page number data T4 of the first page conversion table, so that this file information becomes 2 pages. Set it to “2” to indicate that it consists of.

Each page after the third page below is processed in the same way as the second page described above, and each time, the page number data ↑4 of the first page conversion table is incremented by +1, so ultimately the The page number data T4 of the one-page conversion table represents the total number of pages of the file information.

By the way, when the operator wishes to add a new page to the file information already registered in this manner, the operator first causes the scanner 1 to read the document containing the image information of that page and stores it in the image memory 2. Then, when information (keywords, etc.) specifying the registered file information to which the page should be added is input, the system control circuit 6
The image information stored in the image memory 2 is stored on the optical disk, and the subsequent processing is performed in the same manner as for each page after the second page in the case of multiple page registration described above. Therefore, the conversion table for this newly added page is a multi-page conversion table shown in FIG. The file number address data T12 contains data specifying the number of the file information (already registered) to which the page belongs, and the optical disc track block address data T3 contains the storage position information of the page on the optical disc. The address in the optical disk information area M5 of the search information file 10 where the search information file 10 is stored is stored, and the page number in the file information to which the page belongs is stored in the page number data T4 of the first page conversion table. Ru.

In this way, reading of file information consisting of a plurality of pages registered in the information file device as shown in FIG. 1 is performed as follows.

First, when the operator inputs a keyword or the like using the keyboard 5 in order to specify the file information that the operator desires to read, the system control circuit 6 selects the search information file 10.
The conversion table area Ml of is searched from its top address to find the first page conversion table corresponding to the input keyword.

Then, the system control circuit 6 outputs the optical disc track block end address data T3 of this first page conversion table.
According to the address stored in the optical disc information area M5, storage position information is read out from the optical disc information area M5 and provided to the optical disc device 9. As a result, the image information of that page is read from the optical disk, temporarily stored in the image memory 2, and then stored in the image memory 2.
displayed on the RT display 4.

By the way, since the page number data T4 of the first page conversion table of the first page read as described above stores the number of pages constituting the file information,
If the value is not 1, the system control circuit 6 continues to read the second and subsequent pages.

That is, the system control circuit 6 uses the search information file 1 this time.
0 conversion table area M1 is searched in order from the last address to the first address, and data with the same file information number as the file information specified by the input keyword etc. is retrieved from the file number address data T1.
Find the multi-page conversion table stored in 2 and convert the optical disk track block address data T3.
and page number data T14. Then, the system control circuit 6 reads storage position information from the optical disc information area M5 according to the address stored in the read optical disc trunk block address data T3,
This is given to the optical disk device 9. As a result, the image information of the second page is read from the optical disk, stored in the image memory 2, and displayed on the CRT display 4.

Thereafter, the third and subsequent pages are similarly read from the optical disc.

The above-mentioned process of reading each page after the second page can also be performed when each page is registered consecutively following the first page, or when a later page is added to already registered file information. Even in the case where the file number address data T12 matches, the multi-page conversion table matching the file number address data T12 is searched, and the optical disk trunk block address data T3 is read out, so that processing is performed in exactly the same way.

〔effect〕

As described above, according to the present invention, it is possible to register multiple pages in the same file information at any time, whether newly registering file information or adding to already registered file information. Therefore, even in the case of a configuration in which one information file device is operated by a plurality of terminal input devices, it is possible to register a plurality of pages in the same file information.
