JP2601449B2 - Unconfirmed character display processing method in Japanese editing device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] Japanese-language editing includes a display, displays a Japanese-language document to be edited on the display, and executes a process of inserting characters into a Japanese-language document having meaning on a line-by-line basis. In the non-determined character display processing method of the device, when characters are inserted into a certain line, the part to be displayed on the screen is displayed while feeding the line only, and if the original data overflows from the display screen, The original data is saved in a previously prepared evacuation buffer. If input characters for insertion overflow from the display screen, the overflowed characters are saved in the evacuation buffer and provided on the display screen in advance. In a Japanese-language editing device that is configured to display the overflowing input characters in the designated escape line display area and to improve the operability of the display at the time of insertion It discloses a determined character display processing system.

[Industrial applications]

The present invention relates to a screen display processing method for unconfirmed characters when inserting characters in a Japanese editing device, and in particular, when inserting characters into a document that has meaning on a line-by-line basis, displaying data from the next line onward. The present invention relates to an unconfirmed character display processing method in a Japanese editing device that enables easy-to-read display without affecting the character.

[Conventional technology]

FIG. 10 shows a display example at the time of insertion according to the conventional method. In FIG. 10, G represents a display screen, and C represents a cursor.

In general, a conventional Japanese word processor edits solid-written documents, so for example, Fig. 10 (a)
In the display state as shown in the figure, when an insertion instruction is performed by pressing the "insert key" or the like, the display as shown in FIG. 10 (b) or (c) is performed. In the method shown in FIG. 10 (b), the character after the cursor on that line is moved and displayed in a retreat line display area provided below the display screen G, and the character after the next line is erased from the screen. , Secure a screen area where characters to be inserted are written.

Further, in the method shown in FIG. 10 (c), when an insertion instruction is given, the entire character after the current cursor is lowered by one line as it is, so that a writing area for the inserted character is secured.

[Problems to be solved by the invention]

By the way, in the case of a Japanese editor or the like for inputting document data arranged in units of one line, there are the following disadvantages in the display mode of a solid document as shown in FIG. That is, in the case of FIG. 10 (b), the document data of the next and subsequent lines are deleted from the screen, so that it is difficult to grasp the whole. In addition, in the case of FIG. 10 (c), if there is an insertion character exceeding the display of one line, it is necessary to display the part which was previously displayed by one line down by one line.

When a character is inserted into a Japanese document that has a meaning on a line basis instead of a solid document, the insertion is almost always contained within the line, and a display processing method suitable for that is desired. However, if the insertion process is performed while the display of the next and subsequent lines is fixed, the kana-kanji conversion must be performed in the case of a Japanese editor or the like. May not be displayed. Further, since the length of the reading is different from the length after the actual kanji conversion, the display of characters overflowing from the screen may disappear or appear, making it difficult to see.

In particular, in the case of a so-called horizontal expanded document in which the length of one line is larger than the width of the display screen, if the input data is carried over to the next line, the characters that have been hidden from the screen are suddenly displayed. Such an unnatural display as described above occurs.

[Means for solving the problem]

The present invention solves the above problem, and presupposes that data is not carried over to the next line. By moving only the line at the cursor on the screen, it is easy to see and use a non-determined Japanese editing device. Provide a character display processing method.

 FIG. 1 shows a basic configuration diagram of the present invention.

In FIG. 1, reference numeral 11 denotes a keyboard, 12 denotes a keyboard control unit that controls the keyboard 11, 13 denotes a data input unit, 14 denotes an insertion instruction detecting unit that detects pressing of an “insert key”, and 15 denotes an insertion instruction detecting unit 14. The insertion processing unit to be started, 16 is an editing processing unit for executing general editing processing other than the insertion processing, and 17 is a save line for displaying overflowing input characters on the display screen in advance or at the start of the insertion processing. A retreat line display area setting unit for providing a display area for the insertion processing, an insertion processing initial setting unit 18 for initializing a buffer and the like used for the insertion processing, a screen display character number management unit 19 for managing the number of screen display characters in a character insertion line, 20 is an insertion position pointer that stores the insertion position on the screen, 21 is a displayable character number storage unit that stores the number of characters that can be displayed on the screen, and 22 is the original data in the character insertion line when the insertion character is input. The original data saving unit 23 saves the data when it overflows the screen. The input data 23 saves the data when the characters entered for insertion overflow the display screen and sets it in the save line display area. Evacuation unit, 24 is a screen display buffer that stores the data of the character insertion line to be displayed, 25 is an evacuation buffer that saves overflowing data in the character insertion line, and 26 stores data for kana-kanji conversion. A conversion dictionary, 27 is a kana-kanji conversion processing unit for converting a reading into an expression mixed with kanji, 28 is a display control unit for performing display control, and 29 is a display.

When an “insert key” is input from the keyboard 11, the insertion instruction detection unit 14 activates the insertion processing unit 15. Insertion processing unit
In step 15, first, the initial setting of the screen display buffer 24 and the evacuation buffer 25 is performed by the insertion processing initial setting unit 18.
The screen displayable character number management unit 19 sets the current cursor position to the insertion position pointer 20, and displays the displayable character number storage unit.
In 21, the number of characters that can be displayed on the screen is set by subtracting the value of the insertion position pointer 20 from the screen display width.

Next, when an insertion character is input, the screen displayable character number management unit 19 checks the value of the displayable character number storage unit 21 and
The original data saving unit 22 or the input data saving unit 23 is started. When the inserted data causes the original data to overflow from the screen display buffer 24, the original data saving unit 22 is activated,
The original data saving unit 22 transfers the overflowing characters to the saving buffer 25, and stores the input characters in the screen display buffer 24. On the other hand, if characters input for insertion also overflow the screen display buffer 24, the input data saving unit 23 is activated, and the input data saving unit 23 stores the input characters in the saving buffer.
The input characters are stored in the evacuation line display area provided by the evacuation line display area setting unit 17 while being stored in the evacuation line display area setting unit 17. Data such as each buffer and the insertion position pointer 20 are invalidated when the insertion processing is completed.

[Action]

According to the present invention, displayable characters are managed by the screen displayable character number management unit 19, and the original data overflowing from the display screen of the character insertion line is saved in the save buffer 25. The subsequent display will not be disturbed. Also,
If the character entered for insertion overflows the display screen on that line, the overflowed part is the evacuation buffer.
25, and the input characters are displayed in the evacuation line display area provided below the screen, for example, so that the display of the input characters does not disappear. In this escape line display area, only the input characters are displayed, and the original data is not displayed. Therefore, especially in the case of a horizontally extended document or the like where the length of one line is larger than the width of the display screen, it is hidden from the screen. There is no unnatural display such as sudden display of characters.

〔Example〕

2 to 7 show examples of display modes for explaining an embodiment of the present invention, and FIGS. 8 and 9 show a processing flow of the embodiment of the present invention. In the figure, symbol G indicates a display screen, C indicates a cursor, CR indicates a line feed mark, and R indicates a retreat line display area.

For example, assume that the "insert key" is pressed in the state of the display screen G shown in FIG. In the screen display buffer 24,
Data of one line of the line where the cursor C is located is moved. The data stored in the screen display buffer 24 is displayed on the screen in principle. In addition, the position where the cursor is placed,
That is, the insertion start position is evacuated to the insertion position pointer 20, and information on how many more characters can be input up to the maximum screen display character number is stored in the displayable character number storage unit 21.

Next, when data to be inserted such as "chu" is input from the keyboard 11, the input characters are displayed as shown in FIG. 3 while shifting the characters after the insertion position pointer 20 backward. To go. At this time, if characters after the cursor C overflow from the screen display buffer 24, that is, the display screen G, the data is moved to the save buffer 25. By entering three characters,
3 is added to the insertion position pointer 20, and 3 is subtracted from the value of the displayable character number storage unit 21.

Further, when "sho" is input after "chu", the number of characters that can be displayed on the screen becomes 0 or less, and characters to be inserted overflow the screen. In this case, as shown in FIG. 4, the overflow data is displayed in the evacuation line display area R provided at the bottom of the screen, and at the same time, the data is moved to the evacuation buffer 25.

For example, by inputting the “execution key”, the insertion data is determined by the expression “abstract”, and when the insertion processing is completed,
Character feed is performed as shown in FIG. Simultaneously with the end of the insertion processing, the data in the screen display buffer 24, the save buffer 25, the insertion position pointer 20, and the displayable character number storage unit 21 are invalidated.

For example, as shown in FIG. 6, suppose that the expression "Abstract" has been obtained by converting "Chuushokitaku" to Kana-Kanji characters. The original data of the line saved in the save buffer 25 is not displayed in the save line display area R. At this time, when the end of the insertion is notified by the key of the "execute key", the contents of the evacuation buffer 25 are moved as shown in FIG. 7, and the insertion process ends. The contents of the buffer etc. are invalidated.

Next, an example of a process for realizing the above-mentioned unconfirmed character display will be described with reference to FIGS.

When the "insert key" is depressed, first, a process P1 shown in FIG.
Determines if the cursor is in the insertable area. If it is not in the insertable area, a message indicating that insertion is not possible is output by processing P2, and the insertion processing ends.

If it is an insertable area, one row of data of the line where the cursor is located is read by the process P3, and the cursor position is evacuated to the insertion position pointer 20. Further, the evacuation buffer 25 is cleared to 0, the number of characters displayed on the screen is calculated, and the calculated number is stored in the displayable character number storage unit 21.

Next, in process P4, characters are read from the keyboard 11, and character input is awaited. If there is a character input, it is determined in process P5 whether the input character overflows from the current line. If the input characters do not overflow from the line, it is determined in process P6 whether the original data overflows from the screen.

Save buffer when original data overflows from the screen
After moving the data overflowing in 25, by processing P8,
Displays the entered characters on the screen. After that, the control is moved to the process P11.

If it is determined in the process P5 that the input characters overflow from the screen, the input characters overflowing the evacuation buffer 25 are moved in a process P9. Then, in process P10, the input characters are displayed in the save line display area.

By the process P11, the initially set values, that is, the contents of the insertion position pointer 20 and the displayable character number storage unit 21 are updated.

In process P12, it is determined whether or not there is a "conversion key" key press. If there is a "conversion key" key press, a conversion process is executed in process P13. This conversion processing will be described later with reference to FIG.

In process P14, it is determined whether or not there is a key of the "execution key". If not, the process returns to process P4 and repeats the same process. If there is a key of the "execute key", the data of the screen display buffer 24 is displayed on the screen by the process P15.
By the process P16, it is determined whether or not there is data in the save buffer 25. If there is data, the data is displayed on the next and subsequent lines by process P17.
The insertion processing ends.

The conversion process in the process P13 is performed as shown in FIG. First, the kana-kanji conversion is performed by the process P20 shown in FIG. 9 to extract an expression mixed with kanji. By the process P21, it is determined whether or not the expression of the conversion result can fit on the screen.

When entering the screen, next, in process P22,
It is determined whether or not the character feed is necessary. If necessary, the original data in the screen display buffer 24 is filled and character feed is performed in process P23. After that, the extracted expression
Move to the screen display buffer 24, and display the contents of the screen display buffer 24 on the display screen by process P25. In the process P26, it is determined whether or not the "conversion key" has been hit again. If the "conversion key" has been hit, the process returns to the process P20 and the same process is repeated in order to process the homophonic expression. . If there is no "conversion key", control is returned to the caller.

If the expression does not fit on the screen in the judgment in the process P21, the original data in the evacuation buffer 25 is shifted in the process P27. Then, by the process P28, the expression is moved to the screen display buffer 24 and the save buffer 25.
Next, in process P29, the contents of the screen display buffer 24 are displayed, and data overflowing to the save line display area is displayed.
After that, the control is shifted to the process P26.

〔The invention's effect〕

As described above, according to the present invention, the input characters overflowing from the screen are displayed in the save line display area, and do not affect the data of the next and subsequent lines. Therefore, a display that is easy to see and use can be realized. Further, there is an effect that the speed of the insertion processing is increased, and the state after the end of the insertion processing can be immediately recognized.
