JPH0455954A - Document data storing method for electronic filing device - Google Patents

Abstract

PURPOSE:To omit the copy of the document image data when only the document retrieving data is changed by storing these two data in the separate files of data for document retrieve and of data for document image and then pointing these files by means of the pointers respectively. CONSTITUTION:A file index includes the document retrieving pointers 4, 6 and 8 and the document image pointers 5, 7 and 9 respectively. The pointers 4, 6 and 8 point the positions of the document retrieving data files 10 - 12. Meanwhile the pointers 5, 7 and 9 point the positions of the document image data files 20 - 22 respectively. Thus both document retrieving and image pointers can point the data files independently of each other. Then only the document retrieving data can be changed just by describing additionally only the document retrieving data files and pointers to an optical disk. Meanwhile the document image data can be used as they are.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for storing document data in an electronic filing device;
In particular, the present invention relates to a method for storing document data in an electronic filing device using a write-once optical disc.

[Conventional technology]

In the conventional document data storage method of this type of electronic filing device, as shown in FIG. 2, a file containing document search data 10 to 12 and document image data 20 to 22 of each document is stored on an optical disk. The pointer is pointed at each file index 30-32.

[Problem to be solved by the invention]

In the document data storage method of the conventional electronic filing device described above, when only the document search data 10 to 12 are changed, for example, the document name or the search keyword is changed, the document image data 20 to 22 are not changed. Even if it's not necessary,
In order to create the same file format, it is necessary to add the original document image data to the new document search data and record it on the optical disc. In general, document search data is much shorter than document image data, and this storage method has the disadvantage that storage capacity is often wasted in the case of write-once optical discs.

[Means to solve the problem]

The storage method of the present invention separately stores a first file containing text image data and a second file containing document search data for searching the document image data on a write-once optical disc, Further, first and second files each indicating the storage location of the first and second files, respectively.
Stores a file index containing a pointer to the file.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a data configuration diagram of an embodiment of the present invention, showing the configuration of files stored in an optical disc. A file index is configured with text search pointers 4, 6.8 and document image pointers 5, 7.9, respectively, and document search data data files 10, 11. 12, and the document image pointers 5, 7.9 point to the positions of the document image data files 20, 21, 22, respectively.

By making it possible to specify data files for document searches and document images separately in this way, if you want to change only the document search data, you can simply add only the document search data files and their pointers to the optical disc. , and the document image data can be used as is.

〔Effect of the invention〕

As explained above, the present invention stores the document search data and the document image data as separate files and points them to each file, thereby making it possible to copy the document image data when only the document search data is changed. This method has the advantage of being able to read out only document search data when creating a search database, and is particularly effective as a method for storing documents on a write-once optical disk.
