Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing device for inputting characters to create text.

[0002]

2. Description of the Related Art Conventionally, while a text is being created by a word processor, a personal computer, or the like, the power may be accidentally turned off, or the created text may be erased due to a malfunction of the system. In particular, when a long sentence is created, the long work up to that point will be attributed to blisters, so the problem is large, and various measures have been conventionally proposed.

For example, there is a method of replacing the memory for storing text with a non-volatile memory. However, the non-volatile memory is expensive, and it is good for creating short sentences, but it is expensive for creating long sentences. Moreover, even if the character information forming the text is left in the memory when the system malfunctions, it is difficult to restore the character normally when the portion controlling the character information is destroyed.

On the other hand, when using an inexpensive volatile memory, there is a method of storing text in an external storage device such as a disk while inputting characters. In this case, even if the text on the volatile memory disappears due to some accident, the text stored on the disk can restore the text. Alternatively, there is a method in which a storage area for a text is placed on a disk from the beginning and only a storage area corresponding to a character input portion is placed on a volatile memory by a virtual storage method and written to the disk one by one.

[0005]

However, if the index portion on the disk is destroyed, the entire text may be damaged and may not be restored.

Therefore, the present invention provides a character processing apparatus and method capable of restoring text even when the power is turned off while the character is input, the system malfunctions, or an accident occurs in the external storage device. The purpose is to

[0007]

In order to achieve the above object, a character processing device according to claim 1 of the present invention stores an input means for inputting a character to create a text and the created text. In the character processing device having the first storage means for displaying and the display means for displaying the stored text, a predetermined amount of character group is newly input from the input means.
Each time a new character is input,
The previously entered character group of the specified amount is regarded as one file
And a storage means for newly storing in the non-volatile memory .

According to a second aspect of the present invention, there is provided the character processing device according to the first aspect, wherein the predetermined amount is a predetermined number of characters, a predetermined number of lines, or a predetermined number of pages.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a character processing device of the present invention will be described.

[First Embodiment] FIG. 1 is a block diagram showing the arrangement of a character processing apparatus. In the figure, reference numeral 1 is a central processing unit (CPU), which controls each unit connected via a bus line 6. A keyboard (KB) 2 has cursor keys and character input keys.

A display device (LCD) 3 displays character information written in a volatile memory (VRAM) 4, which is a write-only memory for display. Reference numerals 5 and 7 are a floppy disk (FD) and a hard disk (HD) as external storage devices, respectively, which store character information and the like.

Reference numeral 8 is a read-only memory (ROM), the inside of which is divided into a plurality of parts, each of which stores unique data. The ROM 8 stores a program storage area (PR) in which a program executed by the CPU 1 is stored.
G) 8a and a font storage area (FONT) 8b in which a character pattern is stored are allocated.

The RAM 9 is a volatile memory, the inside of which is divided into a plurality of parts, each of which is used for its own purpose.
The RAM 9 has a work area (WORK) 9a used for operating a program, a character information area (TEXT) 9b for storing character information, a counter area (CONT) 9c for use as a counter, and an external storage device. Line area (LINE) that stores the number of the first line of the
9d is assigned. Work area (WORK)
9a is also used as a temporary buffer for input characters.

Reference numeral 10 is a color printer (P
RT) 10.

FIG. 2 is a flow chart showing the operation processing procedure of the character processing apparatus. In this embodiment, the character is 10
Every time 0 lines are input, a part of the text is stored in the hard disk (HD) 7 which is an external storage device. The unit to save is 100 lines only at the beginning and 200 lines after that.

When the CPU 1 executes the program stored in the program storage area (PRG) 8a of the ROM 8,
First, the value 1 is set in the first row area (LINE) 9d indicating the first row.
Is set, and the value 0 is set in the counter area (CONT) 9c (step S1).

Subsequently, a key input waiting state is entered (step S2), and when a key is input, it is determined whether or not the key indicates the end of character input (step S3). If it is a key indicating the end of character input, the process is terminated. If it is not a key indicating the end of character input, the character information is stored in the character information area (T
EXT) 9b (step S4).

It is determined whether or not a line break that occurs during character input is detected (step S5). If a line break is detected, the value 1 is added to the counter area (CONT) 9c (step S6). Thereby, the number of rows is counted.

On the other hand, if a line feed is not detected in step S5, the process returns to the key input waiting (step S2) again.

It is determined whether or not the number of lines has become a multiple of 100 (step S7), and if it has become a multiple of 100, it is indicated by a counter region (CONT) 9c from the first line indicated by the first line region (LINE) 9d. The character information up to the line is stored in the hard disk (HD) 7 (step S8). The character information is stored in the hard disk (HD) 7 every time this processing is executed.
Different document names are stored in different areas. On the other hand, if it is not a multiple of 100 in step S7, the process returns to the key input waiting (step S2) again.

The value of the counter area (CONT) 9c is 10
In the case of 0, 100 lines from the first line to the 100th line are saved, and in other cases, 200 lines are saved. That is,
The first to 100th lines are saved with a particularly short number of lines.

FIG. 3 is an explanatory diagram showing a range of a text document stored in the external storage device. The text documents from the first line to the 100th line are stored in the hard disk 7 under the document name of document 100. The text document from the first line to the 200th line has a document name of document 200, and similarly, the text document from the 101st line to the 300th line is document 3.
It is saved under the document name 00. Similarly from line 201
The text document up to the 400th line is document 400
Saved by name. In this way, from line 1 to line 300
The text document in is always stored in two documents in units of 100 lines.

Subsequently, in order to check whether or not the document is the stored document of the first 100 lines, the counter area (CONT) 9
It is determined whether or not c has a value of 100 (step S
9). As a result, when the value is not 100, the first row area (L
INE) 9d is incremented by 100 (step S10),
It returns to the key input waiting (step S2). If the counter area (CONT) 9c has a value of 100, it is necessary to keep the value of 1 in the first row, and the process returns to the key input waiting state (step S2) without doing anything.

The counter area (CONT) 9c has a value of 100.
In the case of 1, it is necessary to keep the value 1 in the first row, so the process returns to the key input waiting state (step S2) without doing anything.

By performing such processing, separate independent documents are stored in the hard disk (HD) 7 in units of 100 lines in the middle of character input and thereafter in units of 200 lines.

[Second Embodiment] Next, the configuration of the character processing device according to the second embodiment will be described.
The character processing device according to the present embodiment has the same hardware configuration as that of the first embodiment. In the first embodiment, the texts are stored as separate documents in units of 200 lines and are duplicated in two documents in units of 100 lines. In the present embodiment, when the text is saved in the hard disk (HD) 7, every part is double saved, but on the one hand, the text is saved as an independent document in page units, and on the other hand, the whole text is saved as one. Save as a document.

FIG. 5 is an explanatory diagram showing the range of text stored in the external storage device. A document name is given to each page. For example, the first page is stored as the document 1 and the second page is stored as the document 2 in the hard disk (HD) 7. Apart from that, the entire text is also saved with the document name "entire document".

FIG. 4 is a flow chart showing the operation processing procedure of the character processing device according to the second embodiment. First, the CPU 1 clears the counter area (CONT) 9c to 0 (step S11). In the present embodiment, the counter area (CONT) 9c is used as a counter for counting page numbers. Subsequently, a key input waiting state is entered (step S12), and when a key is input, it is determined whether or not the key is a key indicating the end of character input (step S1).
3). If it is a key indicating the end of character input, the process is terminated. If it is not a key indicating the end of character input, the character information is stored in the character information area (TEXT) 9b (step S1).
4).

It is determined whether or not a page break that occurs during character input is detected (step S15), and if a page break is detected, the value 1 is added to the counter area (CONT) 9c (step S16). . Thereby, the number of pages is counted. On the other hand, if no page break is detected in step S15,
The process returns to the key input waiting (step S12).

The hard disk (HD) 7 uses the text of the page indicated by the counter area (CONT) 9c as an independent document.
(Step S17).

Further, the entire text input up to this point is stored as an independent document in the hard disk (HD) 7 (step S18), and the process returns to the key input waiting (step S12) again.

In the present embodiment, the timing for saving the entire text is a page break, but it is also possible to save at a finer timing. Since any part of the text is doubly stored in the hard disk which is the external storage device, even if one of them is destroyed, the other can be restored.

In the above embodiment, the text is saved as a separate document for each predetermined number of lines or pages, but it may be saved for each predetermined number of characters.
As a result, division can be performed according to the content.

In the above embodiment, the text is 2
Although the case where the data is stored twice is shown, the data may be stored three times, so that even if an accident occurs in two places, it can be restored.

Further, the external storage device is not limited to a hard disk and a floppy disk, but an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape,
A non-volatile memory card or the like can be used.

Furthermore, the present invention may be applied to a system composed of a plurality of devices or may be applied to an apparatus composed of one device. Further, it goes without saying that the present invention can also be applied to the case where it is achieved by supplying a program to a system or an apparatus. In this case, by reading the storage medium storing the program represented by the software for achieving the present invention into the system or device, the system or device can enjoy the effects of the present invention.

According to the character processing apparatus according to claim 1 of the present invention, to create a text entering characters by the input means, storing the generated text in the first storing means, are the storage Tomo and displayed by the display means the text
Every time a predetermined amount of character group is newly input by the input means.
In addition, this newly input character group of a predetermined amount and immediately before that
The input predetermined character group and the character group as one file,
Since it is newly saved in the non-volatile memory, if the power is turned off or the system malfunctions while entering characters,
Text can be restored from non-volatile memory . Also, before entering the newly input specified amount of characters,
The input character groups are duplicated and saved in two files
Therefore, if one file in the non-volatile memory is defective,
Can also read the same group of characters from other files
It Also, every time you enter a certain amount of characters,
It only saves one file up to twice the size of
The save operation is completed in a short time, and the user

According to the character processing device of the second aspect, since the predetermined amount is a predetermined number of characters, a predetermined number of lines, or a predetermined number of pages, it is possible to perform division according to the content, format, amount, etc. of the text. it can.

According to the character processing method of claim 3, a character is input to create a text, the created text is stored, and the stored text is displayed by the character processing device. At the same time, each time a predetermined amount of character group is newly input, the character processing device makes one file of the newly input predetermined amount of character group and the predetermined amount of character group input immediately before that. As a result, since the data is newly saved in the non-volatile memory, the text can be restored from the non-volatile memory when the power is turned off or the system malfunctions during character input. Also, since the character groups input before the newly input predetermined amount of character groups are stored in duplicate in two files, even if one file in the nonvolatile memory fails, The same character group can be read. In addition, each time a predetermined amount of character groups is input, only one file that is up to twice the predetermined amount is saved, so the saving operation is completed in a short time, and the user input for saving. The period of interruption is short. Therefore, the user can comfortably and smoothly create long texts.
