JPS5830604B2 - External storage control method for document creation device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a document creation device that creates a document while storing it in a work area on an external storage device. The present invention also relates to an external storage control method that allows documents being created to be used effectively.

Japanese word processors have document creation functions, document storage functions, input/output functions, and document structure processing functions.

Figure 1 shows an overview of a Japanese word processor, in which 1 is a keyboard, 2 is a control unit, 3 is a floppy disk device, 4 is a screen buffer, 5 is a display, 6 is an end key, and 7 is a floppy disk drive. 8 indicates a next page key, 8 indicates a previous page key, 9 indicates a storage area, and 10 indicates a work area.

The control section 2 is composed of a microprocessor, etc., and controls the entire word processor.

When creating a document, the operator inputs kana characters from the keyboard 1, and when wanting to convert words written in kana to words written in kanji, performs a kana-kanji conversion operation.

The document being created is stored in the screen buffer 4 and displayed on the display 5.

When one page of document is created, the operator presses the next page key.

Then, the data in the screen buffer 4 is transferred to the work area 10 of the floppy disk device 30.

FIG. 2 shows the configuration of the work area 10. One page is composed of, for example, six sectors, and the ■ sector can store, for example, five lines of documents.

If the operator wishes to view a previously created document during document creation, the operator presses the previous page key 8.

Then, the previous page of the document is read out from the work area 10 and displayed on the display 5.

Documents are created in this manner, and when all desired documents have been created, the operator presses the end key 6.

When the end key 6 is pressed, the document in the work area 10 and the document in the screen layout 40 are moved to the storage area 9 and stored.

In the conventional technology, initialization processing is performed when the power is restored after a power outage or when a bird failure occurs.

This initialization process also erases the 100 documents in the work area, making all the documents created up to that point useless.

The present invention is based on the above consideration, and provides an external storage control for a document creation device that allows documents stored in a work area to be effectively used when a power outage or... The purpose is to provide a method.

For this reason, the external storage control system for the document creation device of the present invention includes a manual section for inputting data, a control section for controlling the entire document creation device, and an external storage device having a storage area and a work area. A document creation device configured to store the document in the work area each time one batch of documents is created, and to move the document in the work area to the storage area and store it when all documents have been created. (1) providing a work area valid flag that is turned on when creating a document using the work area and turned off when the document creation is finished and the document in the work area is transferred to the storage area; When initializing the above work area, check the status of the above work area valid flag, and if the work area valid flag is on, move the documents stored in the above work area to the above storage area, and after all have been transferred. The feature is that the work area valid flag is turned off.

Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 3 is a block diagram of one embodiment of the present invention, 11
12 indicates an initialization control unit, 12 indicates an external storage control unit, and ■ indicates a work area valid flag, respectively.

When the initialization control unit 11 receives the initialization signal, it checks whether the work area valid flag is on or off, and if it is on, it instructs the external storage control 12 to update the work area 10. It is instructed that the data should be transferred to the storage area 9.

The external storage control 12 reads data from and writes data to the floppy disk device 3 based on commands from the outside.

The work area valid flag ■ is turned on when starting to create a document using the work area 10, and is turned off when the document creation is completed and the work area 100 documents have been successfully transferred to the storage area 9. Ru.

The document begins to be created in the word processor,
When the work area 10 is used, the work area valid flag V is turned on.

The completed documents are sequentially stored in the work area 10, and when all document creation is completed, the end key 6 is pressed, and as a result, the 100 documents in the work area are moved to the storage area, and the work area valid flag ■ is turned off. It is said that

In the process of creating a document, if power is cut off and then recovered, the initialization signal is turned on and the initialization control section 11 operates.

The initialization control unit 11 checks whether the work area valid flag ■ is on or off, and if it is on, the work area 100 is activated as described above.
The external storage control 12 is instructed to move the document to the storage area 9.

Upon receiving this command, the external storage control unit 12 moves the documents in the work area 100 to the storage area 9, and turns off the work area valid flag V after all the documents have been moved.

. . . When a disk failure occurs, the initialization signal is turned on and similar work area initialization processing is performed.

As is clear from the above description, according to the present invention, even in the event of a power outage or a bird failure, it is possible to effectively use documents stored in the work area and created up to that point. .
