Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a document processing device such as a Japanese word processor.

2. Description of the Related Art In conventional document processing devices, a cursor is displayed as a blank symbol indicating the next input position, and the cursor can be moved to any position on the screen. On the other hand, CRT
For display devices that cannot display the entire document on one screen, such as the following, only part of the document is displayed on the screen. If you want to move the cursor to an area that is not currently displayed, you must scroll the screen vertically and horizontally to bring the desired area onto the screen.

The cursor is on an input means such as a keyboard.

The cursor can be moved by pressing the cursor movement key. There are four types of cursor movement keys: up, down, left, and right. When you press the cursor movement key once,
The cursor moves one column or line in that direction. When the cursor is located at the top, bottom, left, or right edge of the display screen, pressing a cursor movement key that moves the cursor to the outside of the screen scrolls the screen one digit or one line in that direction.

When a character key is pressed, the character of that key is entered at the cursor position, and the cursor moves one digit to the right.In this case, if the cursor is located at the right edge of the screen, the screen moves one digit to the right. Scroll digits.

If you keep pressing the cursor movement key or character key, the repeat function will work, allowing you to continuously move the cursor, scroll the screen, and input characters at the cursor position.

When the cursor is at this position in Figure 3, pressing the cursor movement key 16r will move the cursor to 'this'.
The screen moves one digit to the right from this to 'sa', and Figure 3C is displayed. If the cursor movement key 16r is continued to be pressed, the repeat function is activated and the cursor attempts to move one digit from 'S' to 'S' again. However, since 'X' is outside the display screen, the screen scrolls one digit to the right and Figure 3d is displayed. If you continue to press the cursor movement key 16r, the cursor will move one digit to the right in sequence from 'shi' to 'su'-'se'-..., and the display screen will also change accordingly. Scroll one digit to the right.

Problems to be Solved by the Invention However, in the above configuration, each time a cursor movement key or a character key is input, cursor movement processing, scrolling processing, and character input processing at the cursor position are performed. Using the repeat function to continuously move the cursor, scroll, and input characters takes a significant amount of time.

The present invention has been made in view of this point, and includes cursor movement processing, scrolling processing, etc. when the repeat function is activated.
It is an object of the present invention to provide a document processing device that improves the processing speed of character input processing and has good operability.

Means for Solving the Problems As a means for solving the above problems, the present invention provides an input means such as a keyboard, and periodically generates a repeat signal when a key on the keyboard is continuously pressed. a repeat control unit; an input buffer that stores codes input from the keyboard; a repeat count counter that is paired with the input buffer and stores the number of times a repeat signal is generated in the repeat control unit for each input code; Analyzing the code received from Kavanofa,
Obtain the number of times stored in the repeat number counter and process the received code for the determined number of times 1
This document processing apparatus includes an input code analysis section that instructs the input code analysis to be performed at the same time, a display control section that displays the screen according to the instructions issued by the input code analysis section, and a display device such as a CRT.

Effect of the Invention With the above-described configuration, the present invention stores the number of occurrences n of repeat signals in pairs with the input code when the repeat function is activated, so n times of cursor movement processing, scrolling processing, or n-time movement to the cursor position is performed. Character input processing can be performed once for a predetermined number of times, and the time required for screen display is shortened.

Embodiment FIG. 1 is a block diagram showing the configuration of a document processing apparatus in an embodiment of the present invention. In FIG. 1, 1 is an input means such as a keyboard, 2 is an input unit for storing codes inputted from the keyboard 1, and 4 is an input unit for storing codes inputted from the keyboard 1, and 4 is an input unit for storing codes inputted from the keyboard 1. A repeat control section 3 that generates a repeat signal at a time is paired with the input cutout buffer 2, and stores the number of times a repeat signal is generated in the repeat control section 4 for each input code.
A repeat count counter 5 receives the input code from the input buffer 2 and the repeat count from the repeat count counter 3, and controls the cursor movement control unit 6 and the text [ - An input code analysis unit that instructs the code control unit 9. The input code analysis section 5 includes an input code register 5a that stores the code received from the input buffer 2, a repeat number register 5b that stores the number of repeats received from the repeat number counter 3, and a predetermined repeat number. It is constituted by a repeat number setting register 5C in which the number of times is stored. Reference numeral 6 denotes a cursor movement control section which receives the cursor movement code of 5E and the number of repeats if the code received by the input code analysis section 5 is a cursor movement code. The cursor movement control unit 6 determines a new cursor position after the movement based on the received cursor movement code and the number of repeats, and stores it in the cursor position register.

. At this time, if scroll processing is necessary, a new cutting position of the text code is found and the value f of the cutting start point register 8 is updated. 9, when the code received from the input buffer 2 is a character code, the input code analysis unit 5 receives the character code and the number of repeats, and corresponds to the cursor position in the text code memory 1o. Text code control units 1 and 11 write characters corresponding to the number of repeats in a section, and after performing cursor movement processing and character input processing for the number of times stored in the repeat number setting register 5C, This is a display control section that receives screen display instructions from the code analysis section 5. The display control section 11 includes a text code cutting section 11a, a display/kunofa 111), a screen display section 11C,
A turn memory 114 comprises a turn memory 114. The text code cutting section 11a has a cutting start point register 8.
The text code is extracted based on the value of and stored in the display buffer 11b. The screen display section 11c
For example, the text code stored in the display file 11b is converted into a font pattern memory 11 (1) and then sent to the display device 12 such as a CRT.
1. At this time, the input code analysis unit 5 sets the repeat count 1/the contents of the register 5b as the repeat count, deletes only the value stored in the register C, and repeats.
The cursor movement or character input instruction is issued repeatedly until the value of the number of times register 5b becomes zero. The operation of the document processing device of this embodiment configured as described above will be explained below using FIG.

When the tau curve reaches the position 'R', the input code analysis unit 5 receives the code '→' from the input cover 2, stores it in the input code register 54, and inputs it to the repeat count counter 3. The repeat count '5' is received and stored in the repeat count register 5b. Since this code is a cursor movement code, the input code analysis unit 5 sends the rightward cursor movement code and the number of times of revi~[· to the cursor movement control unit θ. In this example, '3' is stored in the repeat 1 count setting register 5C, fl,
If so, the input code analysis unit 5 sends the number of repeats and 12 '3' to the cursor movement control unit 6.

The cursor movement control unit 6 uses the sent code and
The new cursor position is determined as the 'the' position based on the number of times the cursor is moved, and is stored in the cursor position register. At this time, the screen will scroll one digit to the right, and it will become ζ4, so
Update the value of the text code extraction start point register 48 to the value after scrolling4, where the person 1 code analysis unit 5:

t" f (1, i number 1 sister 11) (') value becomes '2' by subtracting the value stored in the replay count setting register 5C. The input code analysis unit 5 controls the cursor movement. Further, the rightward cursor movement code and the remaining number of repeats '2' are sent to section 6, the cursor is moved and scrolled by two digits, and the image shown in FIG. 2d is displayed.

Next, the input code analysis unit 5 receives the code '↓' and the number of repeats '2'. Since this code is also a cursor movement code, the same processing is performed, sending the downward cursor movement code and repeat count '2' to the cursor movement control unit 6, and moving the cursor two lines downward. Display Figure 2e.

The input code analysis section 5 receives the code 'A' and the number of repeats '7', and stores 'M' in the input code register 5a.
, when '7' is stored in the repeat count register 6b, the character code I A I and the repeat count '3' are sent to the text code control unit 9, since this code is not a character code. The text code control unit 9 stores the characters IA in the portion of the text code memory 1o that corresponds to the cursor position.
Write three I's in a row. At this time, the input code analysis section 5 simultaneously instructs the cursor movement control section 6 to move the cursor three digits to the right, scrolls the screen three digits to the right, and sets the cursor position register 7 to To update the contents of the starting point register 8, the input code analysis section 5 instructs the display control section 11 to display the screen, and
Figure f is displayed.

Since the value of the repeat count register 6b becomes '4' by subtracting the value of the repeat count setting register 5C, the repeat count '3' is sent again to the text code control unit 9 and the cursor movement control unit 6, and the value shown in FIG. is displayed. moreover,
The input code analysis unit 5 sends the remaining repeat count '1', which is obtained by subtracting the value of the repeat count setting register 5C from the value of the repeat count register 6b, to the text code control unit 9 and the cursor movement control unit 6, and performs the same process. The processing is performed and the second diagram is displayed.

Although the value of the repeat count setting register 5c is predetermined, it may be possible to set the value as appropriate by the operator.

As described above, according to the present invention, when the repeat function is used to perform continuous cursor movement processing, scroll processing, or character input processing at the cursor position, the processing is repeated a predetermined number of times. The practical effect is great because it is done all at once and the time required for screen display is shortened.
