Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an information processing device.

(Prior Art) With the advancement of office automation, information processing devices such as word processors and personal computers have come to occupy a corner of the office as the core of the information processing devices. When creating a document on such an information processing device, the Kana characters or Roman characters entered on the keyboard are converted into Kanji and Kana characters using the system's built-in conversion module, and the desired document is created while checking on the CRT display. . Once a document is created, it is stored in an external memory such as a floppy disk.

By the way, "editing" is an essential function in document creation using such an information processing device. With this editing function, the document once created is proofread and formatted into the desired format.

To edit, use the CRT display, move the cursor to the character position you want to edit, and press "Insert", "Delete", "
This is done by giving instructions such as "correction".

Cursor keys usually have a repeat function; if you keep pressing the cursor key, when the cursor reaches the line boundary position, it will automatically wrap around to the first character position of the next line or the last character position of the previous line. and move sequentially until a key press is released. Furthermore, when the cursor reaches the page boundary position, it is automatically line-feeded and moved to the last line of the previous page or the first line of the next page, and continues to move sequentially until the key is stopped being pressed.

(Problem to be Solved by the Invention) In the above information processing device, if you keep pressing the cursor key, when the cursor reaches the line boundary position or page boundary position, a line feed is automatically performed. An inconvenience occurs when editing a page-crossing section. That is, the cursor may move across a line or across a page against the operator's wishes, and then return to its original position in a hurry. This is a phenomenon caused by a mismatch between human senses and machine processing speed.

The present invention was made based on this, and when the cursor reaches the line boundary or page boundary position of the created document, the cursor temporarily stops, and by detecting the re-pressing of the cursor key, the cursor is moved to a logically connected line/column position. An object of the present invention is to provide an information processing device that can improve the operability of document editing by forcibly moving a cursor to .

[Structure of the Invention (Means and Operations for Solving the Problems)] In order to achieve the above object, the present invention uses cursor keys to move the created document stored in the memory in units of pages or parts thereof. When performing an editing operation, when the operator presses a cursor key with a repeat function, the detection means detects whether the cursor key has been pressed. Then, the moving means moves the cursor in the direction according to the type of cursor key detected by the detecting means. Further, the position detection means constantly monitors the position of the cursor on the memory. When the position detecting means detects that the cursor has reached the line boundary or the unit boundary on the memory, the stopping means temporarily stops the cursor. Once stopped, when the detection means detects that the cursor key is pressed again, the forced movement means moves the cursor located at the second row boundary or the unit boundary to a logically connected position in the memory. Forced to move.

In this way, when the cursor reaches a line boundary or unit boundary, the cursor temporarily stops, which prevents the cursor from crossing a line or page against the operator's will, improving the operability of document editing. .

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
The figure is a block diagram showing the information processing device of this embodiment.

In the figure, 1 is a microprocessor, which controls the entire system according to a program stored in a main memory 2. 2

(Keyboard) unit, which has at least instruction keys for moving the cursor in any direction (down, left, right). A display controller 5 controls the display of data input from the keyboard unit 4 or processed data output from the microprocessor 1 on the CRT monitor 6. In this embodiment, a commercially available LSI equivalent to 11D4G505 manufactured by Hitachi is used. This LSI contains a cursor start raster register that specifies the cursor display start rask address and cursor display mode, a cursor end raster register that specifies the cursor display end rask address, and a cursor register that specifies the cursor display address. It includes registers for displaying a cursor, and a cursor of a desired shape is displayed on the CRT monitor 6 by synchronizing with the scanning line based on the contents of these registers. A video memory 7 stores display contents corresponding to the capacity of one screen (for example, 1200 characters), the microprocessor 1 updates the contents sequentially, and the display controller 5 reads and displays the contents. 8 is a multiplexer into which address information (MADR) output from the microprocessor 1 and address information (RADR) output from the display controller 5 are input, and one side is input by the display timing (DISPTMG) signal output from the display controller 5. is selected and supplied to the video memory 7. 9 is a shift register and 1

)) and convert it to a video signal. IO is an oscillation circuit that supplies a constant frequency signal to the display controller 5 and shift register 9 via a dot counter 11. 1
2 is a data bus, and 13 is an address bus.

The operation of this embodiment will be described in detail below with reference to the flowcharts shown in FIGS. 2-(A) and 2-(B). The microprocessor 1 constantly monitors styx information (key-in data) arriving via the keyboard unit 4 and keyboard controller 3, and operates as follows after a cursor key is pressed.

When a cursor key is pressed (201), it is first determined whether the cursor stop flag is ON (202)
. The cursor stop flag is provided in a certain area of the main memory 2, and becomes significant when the left cursor key is pressed while the cursor is at the beginning of the line.
One is significant when the right cursor key is pressed when the cursor is at the end of a line, and the other is significant when the up cursor key is pressed when the cursor is at the top line of the page. It is made up of the following: which becomes significant when the down cursor key is pressed while the cursor is on the last line of the page. All cursor stop flags are OFF
If F, the type of cursor key (203) and position detection (204 to 207) are performed.

As a result, if it is a left direction specification key and the cursor is at the beginning of the line (204), a flag indicating this is turned ON.
L (21,2) until that key is released (21
3) The movement of the cursor is temporarily stopped, ignoring the key force (214). When the key is released, the process returns to 201 and waits for the cursor key to be pressed. If the cursor is at a position other than the beginning of the line, the cursor display position is moved back one digit to the left.

On the other hand, if it is a right direction specification key and the cursor is at the last column of the line (205), a flag indicating this is turned ON L.
(212), until the key is released (213)
The movement of the cursor is temporarily stopped, ignoring the key force (214). When the key is released, the process returns to 201 and waits for the cursor key to be pressed. If the cursor is located at a location other than the last digit of the line, the cursor display position is incremented by one digit. Also, if the cursor is on the first line of the page (206) for the lx direction specification key, a flag indicating this is set to O.
N L (2]2), until that key is released (2
1, 3) Temporarily stop the movement of the cursor, ignoring the key force (21.4). When the key is released, the process returns to 201 and waits for the cursor key to be pressed. If the cursor is located at a location other than the first line of the page, the cursor is moved to the previous line spacing column position. Furthermore, if it is a down direction designation key and the cursor is on the last line of the page (207), a flag indicating this is turned ON L (212), and the key is ignored until the key is released (213). The movement of the cursor is temporarily stopped (214). When the key is released, the process returns to 201 and waits for the cursor key to be pressed.

If the cursor is on a position other than the last line of the page, the cursor is moved to the next line spacing column position.

Next, the operation when the key is released in 213 and the cursor key is pressed again after returning to 2 old will be described. In step 202, it is determined whether any flag is ON. In this case, since any flag is ON in step 212, the type of cursor key that was pressed again is detected (212).
15). If the key pressed again is the left direction specification key and this key is the same key that turned on the flag (2
1, 8), move the cursor to the last column position of the line before the current cursor position 220), and turn off the flag that was ON (224). If it is a different key in 216, move the cursor back one digit to the left (22g)
, turns off the flag that was on (224). On the other hand, if the key pressed again is the right direction designation key and this key is the same key that turned on the flag (217
), move the cursor to the first column position of the line next to the current cursor position (221), turn ON L, turn off the flag.
(225). If it is a different key in 217, move the cursor one digit to the right (229),
The flag that was ON is turned OFF (225). Also,
If the key pressed again is the upward direction designation key and this key is the same key that turned on the flag (218)
, move the cursor to the same column position on the last line of the previous page222
), turns off the flag that was ON (22G). 2
If the keys are different in step 18, the cursor is moved to the same digit position in the previous line (230), and the flag that was on is turned off (22G). Furthermore, if the key pressed again is a down direction designation key and this key is the same key as the key that turned on the flag (219), move the cursor to the same digit position on the first line of the next page (223), The ON L flag is turned OFF' (227). If it is a different key in 219, the cursor is moved to the same column position in the next line (231), and the flag that was ON is turned off (227). Flag is OFF at 224-227
When this happens, the process returns to 201 and waits for the cursor key to be pressed.

Cursor movement in this embodiment will be described in detail below with reference to the conceptual diagram of the main memory shown in FIG. 3
I and 32 are row boundaries in memory, and 33 and 34 are page boundaries in memory. When the cursor 41 reaches the line boundary 31, it once stops, and then moves to the position 51 when the left direction designation key is pressed again. When the cursor 42 reaches the line boundary 32, it once stops, and then moves to the position 52 when the right direction designation key is pressed again. Further, when the cursor 43 reaches the page boundary 33, it is temporarily stopped and then moved to the position 53 when the upward designation key is pressed again. Further, when the cursor 44 reaches the page boundary 34, the cursor 44 temporarily stops and moves to the position 54 when the down direction designation key is pressed again.

As described above, in this embodiment, when the cursor reaches the line boundary or page boundary position of the created document, the cursor temporarily stops, and by detecting the re-pressing of the cursor key, the cursor is moved to a logically connected line/column position. Since the cursor is forcibly moved to , the cursor does not move across lines or pages against the operator's will.

[Effects of the Invention] According to the present invention, when the cursor reaches the line boundary or page boundary position of the document to be created, the cursor temporarily stops and moves to a logically connected line/column position by detecting that the cursor key is pressed again. Since the cursor is forcibly moved, the operability of document editing is greatly improved.
