Description

The present invention relates to an improvement of an electronic file in which a document is stored and stored in a magneto-optical disk and is displayed by a reference command or is output in the form of a record. The document in the present invention includes image information such as drawings, photographs and graphs.

Recently, a magneto-optical disk capable of storing a large amount of documents has been used as a storage medium for electronic files, and such electronic files have been attracting attention in connection with other office automation equipment.

On the other hand, in the field of filing documents, it is said that the secret of filing is to quickly discard unnecessary documents. Despite this, conventional electronic files do not provide any means for discarding unwanted documents.
For this reason, there is a problem that unnecessary documents increase in the electronic file with the lapse of time and the difficulty of search increases. Moreover, when discarding unnecessary documents, it takes too much time if the user selects each unnecessary document.

An object of the present invention is to solve the above-mentioned problems and prevent the search from becoming difficult due to an increase in unnecessary documents without the user being aware of it. An object of the present invention is to provide an electronic file device that can prevent an increased document from being erased.

To achieve this object, the present invention stores, in a magneto-optical disk, a plurality of documents, a registration date of each document, and a storage period from the registration date of each document, and the stored documents. A magneto-optical disk storage device capable of erasing data, an input device for inputting the document, registration date and storage period to the magneto-optical disk storage device, and a plurality of documents stored on the magneto-optical disk. An electronic filing device comprising an output device for displaying or outputting a desired document in the form of display or storage and a control device for controlling the magneto-optical disk storage device, the input device and the output device, wherein the control device has a fixed cycle. Alternatively, each time a document is output from the output device, from all the documents stored in the magneto-optical disc, a document whose storage period from the registration date has elapsed is detected, and the detected document is The magneto-optical disk storage device is controlled to erase from the magnetic disk, and the control device sets the registration date of the document output by the output device during the storage period to the output date. It is characterized in that the magneto-optical disk storage device is controlled so that the storage term starts anew from the output date by rewriting.

Hereinafter, the present invention will be described in detail based on the illustrated embodiments.

FIG. 1 is a block diagram showing an embodiment of the present invention. The input device 1 inputs, together with a document image, information associated with a document such as a document title, and information regarding a storage end date such as a registration date and a storage period. The storage device 2 stores the document image and information input from the input device 1. The output device 3 displays or outputs the document image. The control device 4 includes a detection unit, a detection command unit, and a discard processing unit, and performs registration control, reference control, discard processing control, and the like.
The timer device 5 measures time and sends a time signal to the control device 4.

When registering a document, as shown in FIG. 2, the registration date M1 and the storage period M2 are stored in the storage device 2 for each document title M3. The registration date M1 is read from the clock device 5. The shelf life M2 is half a year, one year, three years,
It is entered with a rough specification such as 5 years or forever.

Next, the operation will be described with reference to the flowchart of FIG. The unnecessary document discarding process is automatically performed at midnight every day. At midnight, the detection command causes all the stored documents to be referred to by the reference date M1.
And the storage end date M is calculated from the storage period M2 and compared with the current date, and the document whose storage end date M has already passed is detected. Then, the document is erased from the storage device 2.

For documents that are referenced during the specified retention period, the registration date M1 is rewritten to the reference date,
From the date of reference, a new storage period M2 will start anew.

Needless to say, if "permanent" is designated as the storage period, the document will not be discarded. Therefore, "permanent" may be designated for documents that are highly important and cannot be discarded even if no reference is made.

In the storage device 2, the erased area of the document is registered as an open area and is effectively reused.

In the illustrated embodiment, the detection command is issued every day at midnight, but the detection command is not limited to this, and the detection command may be issued at regular intervals or every time the reference is made. Further, the discarding process is not limited to erasing from the storage device 2, but may be so-called invalidated, which is stored in the storage but not output.

Furthermore, if an unnecessary document is detected, do not immediately discard it,
The output device 3 may output an inquiry as to whether or not to discard the document, and discard only the document permitted by the user.

As described above, according to the present invention, the storage period from the registration date elapses from all the documents stored in the magneto-optical disk every certain period or every time the document is output from the output device. Since the detected document is detected and the detected document is erased from the magneto-optical disk, it is possible to prevent the search from becoming difficult due to an increase in unnecessary documents even if the user is not aware of it. In addition, by rewriting the registration date of the document output by the output device during the storage period to the output date, the storage period starts anew from the output date. It is possible to prevent the document of which the degree of importance is increased from being deleted with the passage of.
