JPH06187345A - Document preservation system for word processor - Google Patents

Abstract

PURPOSE:To automatically preserve old version of an updated document and to limit the number of the preserved documents within a specified range. CONSTITUTION:The desired total number of preserved documents is inputted from an input part 6 and stored in a storage part 3. A comparison part 2 compares the number of documents preserved in the storage part with the number of identical documents stored in a 2nd memory part 4 and outputs a signal when they are equal to each other. When a document is updated and preserved in a 1st memory part 7, the document of the oldest version stored in the 1st memory part is deleted in response to the output signal of the comparison part.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a word processor (hereinafter referred to as a word processor), and more particularly to storing updated documents.

[0002]

2. Description of the Related Art Conventionally, when a document created by a word processor is updated, the updated document is saved, and it is possible to save or delete the unupdated document. Generally, a floppy is used to record a word processing document, so the amount of data that can be recorded is limited. Therefore, when a document is updated many times, it may be difficult to decide which version to save, or the version to be saved may be erased by mistake.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. An old version of an updated document is automatically saved, and the number of saved documents is within a specified number of saved documents. The purpose is to be.

[0004]

In order to solve the above problems, according to the present invention, the created document is the first version, the same document is updated and the version number is the second version. +1
In a word processor for addition, an input unit for inputting characters, etc. and designating up to the document version up to which the document last updated is stored, and a document being updated and stored in the input unit desired A storage unit for storing the number of stored documents, a display unit for displaying data in the storage unit, a first memory unit for storing created documents and updated documents, a title of the document, a document version number, etc. A second memory unit for storing, and a comparing unit for comparing the desired number of stored documents in the storing unit and the total number of respective versions of documents of the same file stored in the second memory unit and outputting a signal when they are the same. The updated document is stored, and the version before update is not erased but left in the first memory unit, and the oldest version stored in the first memory unit based on the output signal of the comparison unit. Edition document Constituted by a control unit that supports.

[0005]

With the above arrangement, the desired total number of stored documents is input from the input unit and stored in the storage unit. The comparison unit compares the number of documents stored in the storage unit with the number of identical documents stored in the second memory unit, and outputs a signal when they are identical. When the document is updated and stored in the first memory unit, if there is an output signal from the comparison unit, the oldest version of the document stored in the first memory unit is erased.

[0006]

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, 6 is an input unit for inputting characters and the total number of desired update documents. A storage unit 3 stores the document being updated and the input data. A display unit 1 displays data in the storage unit. 7
Is a first memory unit for storing the created document. 4 is the second
The memory section stores the title and version number of the created document. Reference numeral 2 denotes a comparison unit, which compares the total number of desired update documents in the storage unit 3 with the number of identical documents stored in the second memory unit 4 and outputs a signal if they are the same. Reference numeral 5 denotes a control unit which, when storing the updated document, leaves the previous version of the updated document in the first memory unit, and if there is an output signal from the comparison unit 2, the first memory unit 7
The oldest version of the document stored in is erased and the above-mentioned parts are controlled. 2 and 3 show the data of the second memory unit 4 displayed on the display unit 1. Reference numeral 10 is a document number, which is given in the order of the created documents. 11 is the title,
This is the title of the created document. Reference numeral 12 is a version number, and the version number is added one by one every time the document is updated. In the above configuration, when it is desired to store the updated documents from the input unit 6, the desired total number of updated documents is input. For example, 3 is input as the total number and stored in the storage unit 3. Then, a document A is created and the first created document A becomes the first edition, and when this is updated, it becomes the second edition. Further updating will result in the third edition, as shown in FIG. When updating the third version of the document A in the state of FIG. 2, if the update is instructed from the input unit 6, the first memory unit 7
The data of the third edition of the document A stored in is displayed on the display unit 1. Therefore, the third edition of the document A is updated, and when it is completed, this document becomes the updated document fourth edition. This updated document No. 4
When the instruction to save the version is input, the comparison unit 2 causes the storage unit 3 to acquire the desired total number of updated documents “3” and the first, second, and third editions 3 to 3 stored in the second memory unit 4. And outputs the signal because they are the same. Since the control unit 5 has the output signal of the comparison unit 2, the first version of the document A stored in the first memory unit 7 is deleted and the updated document fourth version is stored in the first memory unit 7.
Remember. Then, the first version of the document A is erased from the data of the title (FIG. 2) of the created document stored in the second memory unit 4, and the second version and the third version of the document A are scrolled up by one line, In the last line, write 4th edition of document A. That is, the contents displayed in FIG. 3 are obtained.

[0007]

As described above, according to the present invention, the storage range of the desired old version of the update document is designated, the update document is automatically saved up to that range each time the document is updated, and if the range is exceeded, the Since the oldest version is erased and the new version is stored, there is an advantage that it is not necessary to worry about which version is to be saved and delete the version to be saved by mistake, as in the conventional case.
