Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an overwrite input control device, and in particular to an improvement of the overwrite input control device in a Japanese document editing device that controls the arrangement of characters using control characters. It is related to.

[Conventional technology]

The Japanese document editing device is comprised of a keystroke input device and a display device that displays kana input from the keystroke input device.

The kana input from the key input device is displayed on the display device, and the kana is converted into kanji by a kanji conversion operation. Of course, displaying kana instead of kanji is achieved by not performing conversion.

By inputting this kana, the Japanese document is edited on the screen of the display device. After inputting a character, the position of the next character to be input is specified on the screen using, for example, a cursor.

On the other hand, document editing involves processes such as line breaks and page breaks. In general, in Japanese document editing devices, in addition to normal characters, control characters such as line feed marks, page break marks, tab marks, etc. are prepared for controlling the arrangement of characters on the screen or printing device.

For example, when a line break is performed, a line break mark is displayed on the screen, and spaces are displayed after that line break mark on the display screen.

However, in order to effectively utilize resources such as screen memory, the screen memory does not store the space following the line feed mark on that line, but instead stores the first character of the next line after the line feed mark.

That is, when displaying on the screen, the data is displayed in the correct format under the control of the set number of characters in one line, control characters such as line break mark, page break mark, dub, etc. from the data in the screen memory.

Therefore, the display screen and the contents of the screen memory do not match after the line break mark or page break mark or before the tab, so for example, even if spaces are displayed on the display screen after the line break mark on the line where the line break mark is displayed, , no space is stored in screen memory, so input is prohibited.

[Problem that the invention seeks to solve]

Therefore, if a character is to be input after the line feed mark, the operator must erase the line feed mark by overwriting, overwrite the desired location, and then add a line feed mark after the overwritten character. This causes the inconvenience of impeding the speed of keystroke input.

[Means for solving problems]

The purpose of the present invention is to solve the above problems, and when inputting characters, it is determined whether or not a character is already displayed at a specified character position (cursor position). If you overwrite it and there are no characters, for example, in the line after the line break mark, this part does not exist in the screen memory as described above, so the screen memory contains the data before the cursor position. The necessary control characters (line feed mark,
By inserting and storing spaces, etc.), the display screen and screen memory are matched, and then the overwritten characters are input.

Furthermore, by automatically moving the line feed mark, which is the control character closest to the initial cursor position, to the position immediately after the overwritten character,
The screen memory provides an overwrite input control device that can prevent unnecessary storage of space thereafter.

The present invention comprises: a kana input means for supplying an input kana, a control character, and a position designation point for the input character; a means for converting the input kana into a kanji; a display section for displaying the kana and the kanji; , a determining means for determining whether or not a character exists at the specified position on the display section, and a controlled character moving section, wherein when a character is input, the specified position is determined by the determining means. If it is determined that there is no character, the control character moving unit inserts at least one of a control character or a space between the input character and the displayed character before the input character, and also inserts the most space at the position specified location. This is achieved by an overwrite input control device characterized in that when the already displayed character located in a nearby position is a page break mark or a line break mark, the mark is moved immediately after the input character.

[Effect]

The overwrite input control method described above is useful when there is no character that has already been input where you want to input a character, for example, when you position the cursor after a line feed mark and want to overwrite the character here, the cursor position and the character immediately before the cursor are Overwriting is done by inserting control characters (spaces, new lines, etc.) between characters.

Therefore, it is not necessary to operate the line break mark by inputting the line break mark after canceling and inserting the line break mark, and the input speed can be increased.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

FIG. 1 is a block diagram of the main parts of the overwrite input control method of the present invention, and FIG. 2 is a flowchart of the present invention.
FIG. 3 is a schematic diagram showing the state of the display section of the present invention.

The Japanese document editing device is composed of an input keying device 1 and a document editing main body 2. Input keying device 1
is the cursor key 11 that specifies the input character position.
It is equipped with a conversion key 12 for converting input kana characters into kanji, a non-conversion key 13 for displaying kana as it is, a line feed key 14 for performing line feed processing, and a page break key 15 for performing page break processing. There is. The operator edits the document on the display section 21 by operating the above-mentioned keys.

The document editing main body 2 includes a detection unit 23 that uses the screen memory 22 to detect whether there is a character at the position where a character should be input, that is, the cursor position, and a detection unit 23 that determines that there is no character at the cursor position. Then,
It is comprised of a control character moving unit 24 that inserts control characters (space, line feed) from the character immediately before the cursor position to the cursor position, and a kanji processing unit 25.

The screen memory 22, the detection section 23, the control character movement section 24, and the kanji processing section 25 are integrated into the display control section 2.
6 performs necessary processing and displays it on the display unit 21.

The operation of the present invention will be explained below with reference to FIGS. 2 and 3. The display screen shows the letter A and line break mark 3.
1, a page break symbol 32, a cursor 33, and a page boundary 34 are displayed. The detection unit 23 performs a test as soon as a character is present at a position where a character is to be input, that is, at a cursor position. This is the state (1) shown in FIG.
Hereinafter, the states in FIG. 2 will be indicated by numbers in parentheses.

If there is no character at the cursor 33 position, that is, in the state shown in FIG. 3a, the control character moving unit 24 operates to move the characters as shown in FIGS. 3a to 3b.
The control character moving unit 24 inserts a line break and a space between the character A immediately before the cursor 33 and the cursor 33 (2).

As a result, the contents of the screen memory 22 are changed to
match the state of the display screen, and then input the overwriting character X.

Furthermore, the control character closest to the initial cursor position, the page break symbol, is replaced with the overwrite character
By moving to the position immediately after , the screen memory 22 can prevent unnecessary storage of space thereafter.

In the example of FIG. 3, the control character closest to the initial cursor position is a page break symbol, but the same applies whether the control character is a line break mark or a tab mark.

After that, perform the normal input processing, enter kana at the cursor position, convert the necessary words to kanji, and edit the document (3). Advances the cursor to the next character position (4).

If there is a character at the cursor position, the control character moving unit 24 does not operate and normal processing is performed.

〔Effect of the invention〕

Now, as can be understood from the above explanation, in short, the present invention allows overwriting of characters in places where there are no characters, without the need for the operator to input a line break mark or a page break mark. It is possible to perform the same operation as , and leave a line break mark and a page break mark, thereby improving the input speed and allowing the operator to input unconsciously, which is highly effective.
