Description

[Detailed Description of the Invention] [Summary] Up movement of the cursor corresponding to four types of cursor movement keys: up movement, up movement, left movement, and right movement.

In addition to the codes for upward movement, left movement, and right movement, each code for upward movement to the right, movement to the lower right, movement to the lower left, and movement to the upper left is determined in advance, and in the typermatic state.

Checks whether two types of cursor movement keys are pressed at the same time, and if two types of cursor movement keys are pressed at the same time, depending on the combination.

It generates and sends codes for moving up right, moving down right, moving down left, and moving up left, as if the keyboard input device physically moved up right and down right.

It is configured as if it had cursor movement keys for downward movement and up and left movement, so that the cursor can be moved diagonally quickly and easily.

[Industrial application field]

The present invention is applicable to 1, for example, a Japanese wort processor.

The present invention relates to a control method for controlling a cursor that indicates the operating position of characters, etc. on a display screen in a personal computer, and particularly relates to a cursor movement key input control method that allows diagonal movement of the cursor.

[Conventional technology]

Generally, in a keyboard input device, when a key is pressed, that is, when a key switch is turned on from off, a code corresponding to the key switch is input. In order to improve operability, modern keyboard input devices have a system where if the same key is held down continuously for a predetermined period of time, the corresponding code will be displayed in the same way as if the key was pressed multiple times. Increasingly, devices with a so-called typermatic function, which repeatedly sends data to the main body processing device, are being used.

By the way, in general, keyboard input devices have up-move and up-move functions to move a cursor that indicates the operating position of characters, etc. on a display screen.

There are four types of cursor movement keys: move person and move right, and when these are pressed, the keyboard input device will
A key code corresponding to each cursor movement key is sent out.

By the way, when a single-body processing device directly scans the key matrix and checks whether each key is on or off,
Although it is not possible to detect multiple key presses at the same time,
When detecting key presses on the keyboard input device side, it is not easy to detect simultaneous presses of a plurality of keys in a single processing device.

In particular, in the typermatic state, if the 1, for example, rAJ key is pressed continuously, the code "A" is
, A, A, A,...'', but if multiple keys are pressed at almost the same time, only the last chord pressed will be sent out consecutively. It turns out.

[Problem that the invention seeks to solve]

In processing units that handle text-editing and graphics.

It is desirable to be able to quickly move a cursor to a desired position. But conventionally.

The cursor movement keys are up, up, and left.

Since there are only four types of right movement, for example, when moving the cursor diagonally to the upper right, it is necessary to alternately press the up movement key and the right movement key to move the cursor in two steps.

For example, some gaming computers detect multiple keystrokes and control the cursor to move diagonally at once.

This is because the main body processing unit must directly identify and control multiple key codes individually.

There are problems in that the control is complicated and the above-mentioned typermatic function etc. cannot be used.

[Means for solving problems]

FIG. 1 is a block diagram showing the basic configuration of the present invention.

In FIG. 1, 10 is a keyboard input device.

11 is a scan code register that supplies a scan signal; 12 is a key matrix consisting of a matrix of key switches; 13 is a key press detection unit that sends a scan code to the key matrix 12 and detects key presses;
]4 is the latest input key register that stores the last input key code.

15 is a code sending unit that sends a code to the main processing device side; 16 is a timer that notifies the time; 17 is a timer monitoring unit that monitors time related to the timer monitoring unit; 18 is a code sending unit that sends a code to the main body processing device; A typermatic status check unit 19 checks whether or not the same key is being pressed, and 19 is a simultaneous press unit that checks whether two or more types of cursor movement keys are being pressed at the same time when the same key is detected to be pressed continuously. A cursor movement key check unit 20 is a diagonal movement that generates a predetermined diagonal movement code that instructs to move the cursor diagonally by matching two or more cursor movement keys when they are pressed at the same time. Code generator.

Reference numeral 23 denotes a main body processing device that includes a central processing unit and a main storage device and processes data according to key inputs.

Reference numeral 24 denotes a reception processing unit that receives the code sent from the keyboard input device 10 side, for example, by interrupting, 25 indicates an input cover sofa, and 26 indicates an input character extraction unit which extracts input characters from the input cover sofa 25.

Reference numeral 27 represents a cursor control unit that controls cursor coordinates indicating an operating position on the display screen, 2B represents a cursor register having cursor coordinate information, 29 represents various processing units that process data, and 30 represents a display.

It may be considered that the detection of the tiermatic state by the tiermatic state check unit 18 is performed in the same manner as in the past.

That is, when the key press detecting section 13 detects a key press, and thereafter the timer monitoring section 17 detects that a predetermined time has elapsed, the typermatic state check section 18 saves the data to the latest input key register 14. The key code that is displayed is set in the scan code register 11, and a scan signal is sent to the key matrix 12. If the output is on, it is determined that the button is continuously pressed.

When a continuous press state is detected and the typermatic state is entered, the simultaneous press cursor movement key check unit 19 determines whether the continuously pressed key is a cursor movement key or not, and whether or not other cursor movement keys are simultaneously pressed. It's not pressed, but I'll check.

When there are cursor movement keys pressed at the same time.

The diagonal movement code generation unit 20 is activated, and instead of nine normal cursor movement codes, the diagonal movement code generation unit 20 generates one of four predetermined diagonal movement codes.
The code is transmitted to the code sending section 15.

The cursor control unit 27 executes a process of adding 1 to each of the X coordinate and the Y coordinate in the cursor register 28 when the input diagonal movement code is 2, for example, a code for lower cloth movement. Therefore.

The cursor will move to the bottom right.

[Effect]

According to the present invention, there are four movements: upward movement, upward movement, left movement, and right movement.
In addition to the codes for cursor up, up, left, and right movement, which correspond to the respective cursor movement keys, the codes for up-right movement, down-right movement, down-left movement, and up-left movement are predetermined. It will be done. When the keyboard input device 10 detects simultaneous pressing of two or more types of cursor movement keys in the typermatic state, it generates and sends a diagonal movement code. Therefore, the nine-body system processing device 23 can process as if a physical diagonal movement key existed. That is, the one-body system processing device 23 is.

The cursor on the display 30 can be moved diagonally by performing diagonal movement code determination control in the same way as the normal vertical and horizontal cursor movement control.

〔Example〕

FIG. 2 shows a diagram for explaining control according to an embodiment of the present invention.

The processing numbers ■ to 0 described below correspond to the processing numbers and months shown in FIG.

(2) The keystroke detection unit 13 shown in FIG. 1 checks whether or not a key has been pressed by sequentially setting scan codes in the scan code register 11. If the key corresponding to the sent scan code is on, an on signal is output from the key matrix 12, and the corresponding contents of the key memory (not shown) that stores the previous scan result information. If there is a change, it is determined that a key has been pressed.

(2) When a key press is detected, a scan code is set in the latest input key register 14, and the code sending unit 15 sends it to the two-body system processing device 23 side.

■ For example, 3°Qms for typermatic monitoring.
Set the timer and return control to process ■.

In particular, this monitoring time may be set short only for cursor movement keys.

■ If there is no new key press, the timer monitoring unit 17
Determine whether a timeout related to Typermatic has occurred. If it has not timed out, return to process ■.

(2) The typermatic state checking unit 18 checks the typermatic state. That is, the content of the latest input key register 14 is set as a scan code in the scan code register 11, and the on/off status of the key matrix 12 is checked.

If it is on, it is determined that the typermatic state is present.

■ If the output of the key matrix 12 is not on, clear the timer 16 and return control to process ■.

■ If a typermatic condition is detected, check to see if a cursor movement key is pressed.

■ If the cursor movement key is not pressed, the code sending unit 15 sends out the latest input key code. Then, control is transferred to process (2).

■ When a cursor movement key is pressed, check whether other cursor movement keys are being pressed at the same time by sending a scan code corresponding to each cursor movement key. If no cursor movement keys are pressed at the same time, control is transferred to process (2) and the same typermatic process as before is executed.

[Phase] If there are multiple cursor movement keys pressed at the same time, select a predetermined diagonal movement code according to the combination and generate that code.

It is sent to the main body processing device 23 side.

■ Specify 2, for example, 25, for the next typermatic monitoring, restart the timer, and return control to process ■.

On the main body processing device 23 side, the reception processing section 24 receives the codes sent from the code sending section 15 by two interrupts, and sequentially sets them in the input buffer 25 in a FIFO format.

The input character extraction unit 26 is.

The code is taken out one character at a time from the input buffer 25, code conversion is performed as necessary, and the character code is passed to the cursor control unit 27 or various processing units 29. If your code is related to cursor movement.

The cursor control unit 27 is activated, and the cursor control unit 27 updates the X and Y coordinates of the cursor register 28.

In conventional cursor movement code, only one of the X or Y coordinates is updated, but in the case of diagonal movement code,
Since both the X and Y coordinates are updated, the cursor will move diagonally on the screen of display 30.

〔Effect of the invention〕

As explained above, according to the present invention, as if the keyboard input device had a cursor movement key for diagonal movement,
You will be able to control the movement of the cursor diagonally. In particular, it is possible to control diagonal movement in the typermatic state, which is effective for two-Japanese word processors, etc., and improves operability without placing a large processing burden on the two-body system processing device. become.
