Abstract

PURPOSE:To automatically delete documents, to save the trouble of the side of a receiver and to prevent the unnecessary reception documents from being accumulated by setting a time when a transmitter deletes the documents. CONSTITUTION:The transmitter generates the documents by a document generation part 3 and a deletion time setting part 4 sets the time for deleting the documents. The set time is written in a deletion of documents time part and is transmitted from a communication part 1 to a computer network. The communication part 1 on the side of the receiver receives the documents from the computer network, stores them in a document storage part 2 and the receiver collates with the documents which a document collation part 5 has received and confirms contents. If they need to be stored, the deletion time setting part 4 rewrites the deletion of documents time part. A time comparison part 8 compares preset time which a time control part 7 periodically controls and the deletion of documents time part stored in the document storage part 2. If the present time passes a deletion available time, a deletion instruction is transmitted to a document deletion part 6, which receives the deletion instruction from the comparison part 8, and deletes the documents.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a document communication device for exchanging documents through a computer network.

BACKGROUND ART In recent years, the number of document communication devices that exchange documents through computer networks has increased.

An example of the above-mentioned conventional document communication device will be described below with reference to the drawings.

FIG. 3 shows the configuration of a conventional document communication device.

In FIG. 3, 31 is a communication unit that communicates with a computer network, 32 is a document storage unit that stores transmitted and received documents, 33 is a document creation unit that creates a document to be sent and is stored in the document storage unit 32, and 34 is a document A document reference section 35 refers to the received document in the storage section 32, and a document deletion section 35 deletes the document stored in the document storage section 32.

The operation of the document communication device configured as described above will be described below.

In a conventional document communication device, a document communication device on the sending side sends a document created by a sender using a document creation unit 33 from a communication unit 31 to a computer network.

The document communication device on the receiving side receives the document. In the document communication device on the receiving side, the communication unit 31 receives the document from the computer network and stores it in the document storage unit 32. The recipient uses the document reference section 34 to check the contents of the received document and retains it until necessary. Thereafter, when the recipient determines that it is okay to delete the document, the document deletion unit 35 deletes the received document.

Problems to be Solved by the Invention However, with the above configuration, the deletion of the communicated document is entirely left to the discretion of the recipient, and like a message, it is retained until a predetermined time and destroyed after that time. Even if it is okay to delete documents, the recipient has to delete them, which poses a problem in that it is time consuming and that unnecessary received documents tend to accumulate.

In view of the above-mentioned problems, the present invention provides document communication that automatically deletes documents by setting a time for document deletion by the sender, reducing the effort on the recipient's side and preventing unnecessary received documents from accumulating. It provides equipment.

Means for Solving the Problems In order to solve the above problems, the document communication device of the present invention includes:
The sender side has a deletion time setting part that specifies the time when the document will be deleted, a time management part that manages the current time, and periodically compares the current time with the deletion time of the document to determine whether it should be deleted and delete the document. The device is equipped with a time comparison section that issues a deletion instruction to the section.

According to the above-described configuration, the present invention periodically checks and deletes unnecessary documents, and for documents such as notifications for which the sender specifies the deletion time, the receiver can delete the document. There is no need to spend time deleting
There is no need to worry about unnecessary received documents accumulating.

Embodiment Hereinafter, a document communication device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows the configuration of a document communication device in an embodiment of the present invention. In FIG. 1, 1 is a communication unit that communicates with a computer network, 2 is a document storage unit that stores transmitted and received documents, 3 is a document creation unit that creates a document to be sent and stores it in the document storage unit 2, and 4 is a transmission unit. 5 is a document reference section that refers to the received document in the document storage section 2; 6 is a document deletion section that deletes the document stored in the document storage section 2; 7 is a time management unit that manages the current time; 8 is a time management unit that periodically compares the current time managed by the time management unit 7 with the deletion time of the document, determines whether it should be deleted, and issues an instruction to the document deletion unit 6; This is a time comparison section.

FIG. 2 shows the structure of a document exchanged by a document communication device in an embodiment of the present invention. 21 is a header portion that holds various document management information; 22 is a document portion that holds the contents of the document; and 23 is a deletion time portion that is part of the header portion 21 and holds the deletion time of the document.

The operation of the document communication device configured as described above will be explained below.

First, the sender creates a document using the document creation section 3 using the document communication device on the sending side. Then, the deletion time setting unit 4 sets the time at which the document is to be deleted. The deletion time setting section 4 writes the set time in the deletion time section of the document shown in FIG. 2-23. The document created after that is Communication Department 1
is sent to the computer network.

The document communication device on the receiving side receives the document.

In the document communication device on the receiving side, a communication unit l receives a document from a computer network and stores it in a document storage unit 2. After the recipient refers to the received document using the document reference section 5 and confirms its contents, if it is necessary to save the document, the recipient deletes the received document in the deletion time section 23.
is rewritten by the deletion time setting unit 4. You can leave it as is if you don't need it.

The time comparison unit 8 periodically compares the current time managed by the time management unit 7 with the deletion time field 23 of the received document stored in the document storage unit 2, and determines whether the current time has passed the deletion allowed time. If so, a deletion instruction is sent to the document deletion section 6. The document deletion unit 6 executes document deletion upon receiving the deletion instruction from the time comparison unit 8.

Effects of the Invention As described above, the present invention allows the sender to set the document deletion time, and the time management section to periodically check and delete the document, thereby eliminating the need for the recipient to take any effort and eliminating unnecessary received documents. It is possible to provide a document communication device that does not have to worry about becoming loose.
