Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a system including a display device such as a computer, word processor, electronic typesetting device, etc.1, and particularly to a control method for a cursor displayed on the display device.

(Prior Art) Generally, a cursor indicates the coordinates of a target point when inputting characters, images, etc. on a display device, and a cursor is a square or a square on the display device.
It is displayed as a cross or the like.

Conventionally, when an operator wants to move a cursor on a display device up, down, left, or right, he or she operates a cursor control key provided for each direction.

FIG. 3 is a block diagram showing an example of a conventional cursor control method.

In this cursor control method, the cursor position storage means 4
The horizontal address and vertical address of the position where the cursor is currently displayed are stored, and when a cursor movement instruction is input from the keyboard 1, the cursor position changing means 5 changes the horizontal direction address in the cursor position storage means 4. Add or subtract ``1'' to or from the address or vertical address to obtain a new horizontal address or vertical address at which the cursor should be displayed, and add or subtract the horizontal address to the horizontal cursor register 41 of the cursor position storage means 4. The vertical address is stored in the vertical cursor register 42.

Then, the cursor display control means 6 refers to the horizontal and vertical addresses in the cursor position storage means 4 and moves the h-curve.

Next, a cursor movement operation using this cursor control method will be explained with reference to FIG.

In FIG. 4, the display position of the cursor is a portion of the display screen 2d indicated by a "mouth" mark.

Assuming that the cursor is now displayed at position 21, the cursor position storage means 4 stores the horizontal and vertical addresses of position 21. At this time, when the right cursor control key of the keyboard 1 is pressed once, the cursor position changing means 5 takes in each address stored in the horizontal and vertical cursor registers 41 and 42, and changes only the horizontal direction address. da I I+ is added and stored in each register again. Thereafter, the cursor display control means 6 displays the cursor by referring to each address of the horizontal and vertical cursor registers 41 and 42.
The cursor will move to position 22. If you press the left cursor control key, the cursor will be displayed at position 24 by subtracting "1" from the horizontal address to find the horizontal address. When the direction cursor control key is pressed, the cursor is moved to position 23 and 25 respectively by subtracting or adding 1' to the vertical address to find the vertical address.
will be displayed.

[Problem to be solved by the invention]

In the conventional cursor control method described above, the cursor can only be moved one step with one key operation, so if you want to make a large movement, you have to perform key operations for the number of steps you want to move while counting the number of operations. However, there is a drawback that the number of tasks increases due to decreased work efficiency, increased worker fatigue, etc., and productivity deteriorates.

An object of the present invention is to solve the above-mentioned drawbacks, reduce the number of operations of the cursor control keys, and move the cursor to a target point in a shorter time.

[Means to solve the problem]

The cursor control method of the present invention has a keyboard equipped with a cursor data input key for inputting the amount of movement corresponding to the direction of movement of the cursor, and an area for storing the amount of cursor movement for each direction of movement (up, down, left, and right). an amount storage means, a movement setting means for storing the movement amount input from the cursor data input key in a corresponding area of the movement amount storage means, and a cursor position storing means for storing the horizontal address and vertical address where the cursor is displayed. Storage means and cursor control key: When a movement direction is specified, the cursor is displayed by referring to the movement amount in the specified direction stored in the movement amount storage means and the address stored in the cursor position storage means. cursor position changing means for determining the horizontal and vertical addresses of the cursor position storage means and storing the addresses in the cursor position storage means; and a cursor display control means for moving the cursor.

[Effect]

The cursor control method of the present invention allows the cursor to be moved from the cursor data input key. The amount of movement is input corresponding to the direction of movement, the amount of movement is memorized for each direction of movement, and when a cursor movement instruction is input from the cursor control key, it is based on the address on the screen where the cursor is currently displayed. The cursor is displayed by calculating a new address to be displayed by referring to the movement amount corresponding to the movement direction.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the cursor control method of the present invention, and FIG. 2 is a diagram showing an example of a cursor movement operation according to the present embodiment.

This embodiment uses a keyboard 1 as an input means, a cursor movement amount setting means 2, and a cursor movement! 7JfIi is composed of a storage means 3, a cursor position storage means 4, a cursor position change means 5, a cursor display control means 6, and a display device 7.

The keyboard 1 includes cursor control keys for instructing the movement of the cursor in up, down, left and right directions, and cursor data input keys for inputting the amount of movement corresponding to the movement direction of the cursor. After the cursor is moved, the storage means 3 stores the keyboard 1
It has areas 31 to 34 for storing movement amounts input from.

The cursor movement amount setting means 2 stores the movement amount input from the keyboard 1 in the area of the cursor movement amount storage means 3 in the corresponding movement direction. This amount of movement is one unit of cursor movement, and one operation of the cursor control key moves the cursor by the amount of movement. The cursor position storage means 4 includes a horizontal cursor register 41 and a vertical cursor register 42, each of which stores a horizontal address and a vertical address on the screen where the cursor is currently displayed. When an instruction to move the cursor is input from the cursor control key, the cursor position changing means 5 stores the corresponding movement amount in that direction from the cursor movement amount storage means 3 and the horizontal and vertical addresses from the cursor position storage means 4. , respectively, and calculate the horizontal and vertical addresses to be newly displayed and store them in the cursor position storage means 4. After the cursor position changing means 5 stores the horizontal and vertical addresses in the cursor position storage means 4, the cursor display control means 6 refers to these addresses and displays the cursor at the corresponding address on the display device 7. .

Next, the cursor movement operation according to this embodiment will be explained with reference to FIG.

Here, as the illumination in the vertical and horizontal directions, ゛2''

At this time, if you press the right cursor control key on keyboard 1 once, the address of the new position to be displayed is determined by the horizontal and vertical addresses of position @21 and the amount of movement in the right direction '3'. seek.

Here, since the moving direction is rightward, the vertical address does not change, and the cursor display address is obtained by adding the moving amount '3' to the horizontal address. As a result, the cursor is at position! It moves three steps to the right from 21 and is displayed at position 22. Further, in the case of downward movement, the horizontal direction address does not change, and the display address is obtained by adding the downward movement amount "4" to the vertical direction address, and the cursor is displayed at position @25.

Furthermore, in the case of leftward and upward movement, the display address is obtained by subtracting the amount of movement "1" and "2" from the horizontal and vertical addresses, respectively, and is displayed at positions 24 and 23.

In this embodiment, the amount of movement is set in advance, but it is also possible to change the amount of movement depending on the direction of movement each time the cursor is moved.

〔Effect of the invention〕

As explained above, the present invention stores the amount of movement corresponding to the direction of movement, and when moving the cursor, refers to the address of the currently displayed position and the amount of movement corresponding to the corresponding direction. By calculating the display position, the amount of cursor movement can be set freely, and when a large movement is required, the desired movement can be made with a simple key operation, improving work performance and reducing worker fatigue. As a result, the number of tasks is reduced and productivity is significantly improved.
