Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention searches for data stored in an external storage medium such as a document or image data (hereinafter abbreviated as drawing data), and erases pages of an electronic filing device for displaying or printing on a display device. It is about the method.

[0002]

2. Description of the Related Art Recently, electronic filing devices for registering and retrieving document data have come into use. Some of these devices have a function of updating the page drawing data. That is, when the page is updated, the old document data becomes the old one version, and the updated document data becomes the latest version. When further updating this page, the updated document data becomes the latest version, the old latest version becomes the old 1 version, and the old old version becomes 1 more sequentially.
Each becomes an older version. This is called page version control. There are roughly the following two methods for deleting this version. In method 1, by deleting the latest version, all the old versions are also deleted. In the method 2, arbitrary versions are deleted one by one.

[0003]

However, each of these methods has the following problems. In method 1,
If the user registers incorrect page data when updating the version, only the registered latest version cannot be deleted. Further, in the method 2, the operation becomes complicated when it is desired to erase all the latest version and old version of the page.

[0004]

[Means for solving the problem] When deleting the latest version, use whether to delete only the latest version, delete all the old versions, or check the old version. The latest version and all the old versions, depending on the input method and the input
Alternatively, a means for sequentially displaying old versions is provided.

[0005]

According to the present invention, when erasing a page having an old version, it is possible to erase only the latest version, or the latest version and all the old versions thereof, according to the user's selection.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a block diagram of an electronic filing apparatus which is an embodiment of the present invention. The central processing unit 1
Controls each device and makes logical decisions. The user inputs a desired command using the mouse input device 6, and at the time of registration, the document image data is once read from the scanner 8 into the main memory device 2 and then processed and processed through the magneto-optical disk device 3 together with management information. Write on the magneto-optical disk 4. At the time of retrieval, the desired document input by the user is read from the magneto-optical disk 4 via the magneto-optical disk device 3 and displayed on the display device 5 or output to the printer 7.

FIG. 2 is a page management table for managing the storage address of the latest version data of a page on the magneto-optical disk, the old version number, and the storage address of the old version data, which is an embodiment of the present invention. Here, one page can have a maximum of three old versions.

Consider a document having a page management table shown in FIG. That is, this document has 2 pages, and page 1 has 2 pages.
Has two older versions. Here, it is assumed that the user uses the mouse input device 6 to input a command to erase page 1 of this document. At this time, referring to the page management table, it is found that page 1 has up to the old 2 version, so that the central processing unit 1 displays the command menu as shown in FIG.

If the user selects "Delete only latest version" with the mouse input device 6, the old version of page 1 is updated by 1 version each, and the number of old versions of page 1 is decreased by 1 to 1. become. As a result, the page management table becomes as shown in FIG.

On the other hand, if the user selects "erase all versions" with the mouse input device 6, page 2 of the page management table will be displayed.
Content of the entry is written to that of page 1. After that, 0 is written in the entry of page 2. as a result,
The page management table is as shown in FIG.

When the user selects "display old version" with the mouse input device 6, the central processing unit 1 refers to the page management table and displays the old version data via the magneto-optical disk device 3. The data is read from the magneto-optical disk 4 and the document data is displayed on the display device 5 at a predetermined time interval in the order of the old 1 version and the old 2 version. This allows the user to determine whether to delete the old version. When the old 2 versions have been displayed, the command menu of FIG. 4 is displayed again.

If the user selects "interrupt", page erasing is interrupted.

[0014]

According to the present invention, when a page having an old version is erased, it can be erased by an erasing method according to the intention of the user, and it is possible to prevent the old version from being erased by mistake. Excellent operability.
