Abstract

An apparatus for moving a cursor finely on a screen moves the cursor in an application program such as a CAD that requires high accuracy. The apparatus includes a mouse button formed at a predetermined portion of a mouse for selecting data; fine movement buttons formed to predetermined portions around the mouse button for moving a mouse cursor upward, downward, left and right by a preset value; and a fine movement interval regulator formed to a predetermined place of the mouse button for providing a fine movement signal per preset time while a user presses the fine movement button.

Claims

1. An apparatus for moving a cursor on a display screen, comprising:

a first device for activating movement of the cursor from one position to another on the display screen by a first distance;

a second device for activating the movement of the cursor by a second distance smaller than the first distance when said second device is activated, wherein said second device includes one or more members, each member corresponding to a different direction of the movement of the cursor; and

a third device for activating said second device in a predetermined time interval, said third device including means for setting said predetermined time interval.

2. The apparatus for moving a cursor on a display screen of claim 1, wherein said one or more members include four members, each member corresponding to a respective one of upward, downward, rightward and leftward directions of the movement of the cursor.

3. The apparatus for moving a cursor on a display screen of claim 1, wherein said means for setting said predetermined time interval includes a sliding switch for controlling said predetermined time interval.

4. The apparatus for moving a cursor on a display screen of claim 1, wherein said means for setting said predetermined time interval includes a dial switch for controlling said predetermined time interval.

5. An apparatus for moving a cursor on a display screen, comprising:

a first device for activating movement of the cursor from one position to another on the display screen by a first distance; and

a second device for activating the movement of the cursor by a second distance smaller than the first distance when said second device is activated, wherein said second device includes one or more members, each member corresponding to a different direction of the movement of the cursor.
