Abstract

PURPOSE:To prevent the deterioration of availability of an optical disk regardless of the copying or shifting frequency of a document file by recording the document file name of a copy receiver and the address of the image data on a copy transmitter to a hard disk. CONSTITUTION:An electronic filing device consists of an image scanner 11, an optical disk device 12, a printer 13, a keyboard 14, a display 15, a hard disk device 16, and an image processor 17. If a document file already registered to the electronic filing device is copied or shifted and registered again, the document file of the copying or shifting destination is newly registered to a hard disk (data base) 16a. Then the address of the image data (written into an optical disk 12a) of the copier or the shifter is stored as the address of the new document file. As a result, the availability of the disk 12a is never deteriorated regardless of the copying or shifting frequency of the document file.

Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to an electronic filing device using a write-once optical disc, and in particular to copying (copying) registered document files.
(copying or moving) method.

``Prior Art and Problems to be Solved by the Invention'' As shown in FIG. 2, an electronic filing device includes an image scanner 11 for reading images. An optical disk device 12 that records and reproduces image data using an optical disk, a printer 13 that prints image data recorded on the optical disk, a keyboard 14 that inputs data and issues various instructions, and monitors image data. It consists of a display 15, a hard disk device (also called a magnetic disk device) 16 that records document names and their addresses registered on optical disks, and an image processor (a type of combinator) 17 that controls and adjusts each of these hardware. Ru. Currently, the optical discs that can be used with electronic filing devices are called write-once type, and data can be freely written and played back.
However, once written data cannot be erased and written again.

Currently, document A is 4 pages of AI to A4, and document B is B.

Let's say that each document consists of four pages of B4 to B4, and each member of each document is input as image data by the image scanner 11, and page 0A is written on the optical disk 12a.
Let the addresses on the optical disk where numbers 1 to A4 are written be al to a4, respectively. Similarly, an optical disk 12a on which documents A and B are written with addresses of pages B to B4 as s to b4 is shown in FIG. 3A together with the addresses.
In the same figure, A+ means page A! The image data is shown. The same applies to others. The document names of documents A and B registered on these optical disks and the addresses a to a4 and s to b4 of the pages constituting each document are entered on the hard disk using the keyboard 14 as shown in FIG. 3B. (database) 16a and used as document management data.

By the way, in an electronic filing device, a document C that is the same as a document A already recorded on the optical disk 12a may be filed separately, called a copy. This is a case where a separate copy of document A is made exclusively for the sales department. In such a case, as shown in FIG. 4, the same document file as the copy source (document A) is separately written to addresses C1 to C4 on the optical disk 12a, and the document C is also written to the hard disk (database) 16a. This was done by registering the name and its address (c+ to c4) on the optical disk.

In addition, in the name of document movement, document A (already registered on an optical disk), which was used exclusively by a certain department, was moved due to circumstances.
There is a case where the document C is registered separately as a document exclusively for another department, and the record of the source document A on the database is deleted. That is, as shown in FIG. 4A, the same document file as the source (document A) is separately written to addresses CI to C4 on the optical disk 12a, and the document name (document C) and its name are written on the hard disk (database) 16a. The addresses (c, to C4) on the optical disk are registered, and all records of the source document name and its address are erased (Fig. 4C).
).

In this way, in the conventional technology, when copying or moving a document file already registered in an electronic filing device and registering a new one, a record is created each time to write the same document file as the copy source or the transfer source. There is a problem in that the optical disc requires a large area, which reduces the usage efficiency of the optical disc.

An object of the present invention is to prevent the usage efficiency of an optical disk from decreasing no matter how many times a document file is copied or moved.

"Means to solve the problem" Storing image data of document files on optical disks,
In a document file copy method of an electronic filing device in which the address is recorded and managed on the hard disk, the present invention records the copy destination document file name and the address of the copy source image data on the hard disk. be done.

“Embodiment” In the electronic filing device of the present invention, when registering a document C that is a copy of a document A that has already been registered, the first
As shown in FIGS. A and B, the image data of document A is not written twice on the optical disk 12a, and a new document C is additionally registered in the hard disk (database) 16a. Addresses a to a of the image data of the copy source (document A) are stored as addresses on the member's optical disk. Therefore, the image data of pages Al to A4 on the optical disk will be pointed from both document A and document C.

In addition, when moving to a document, the destination document C is similarly registered in the database and addresses a1 to a4 are stored, while all records of the source document name and its address in the database are deleted. (Figure 1C).

"Effects of the Invention" According to the present invention, when copying or moving a document file in an electronic filing device, the same document file as the copy source or move source is not written to the optical disk as in the past, but the hard disk drive This is done by newly registering a copy destination or movement destination document file in a database, and storing the address of the copy source or movement source image data (written on an optical disk) as its address. Therefore, no matter how many times the document file is copied or moved, the memory area of the optical disk is not used excessively, and there is no fear that the utilization efficiency of the optical disk will decrease as in the conventional case.
