<p>PURPOSE:To provide the input device which is superior in operability by easily inputting data corresponding to an optional position on a display screen. CONSTITUTION:A central processing unit 3 sets movement quantity of a cursor on the display screen of a display device 2, corresponding to the rotational quantity of a 2nd micro track ball 7 inputted through a control driver 5, larger than the movement quantity corresponding to the rotational quantity of a 1st micro track ball 6. Consequently, when the 2nd micro track ball 7 is operated, the cursor can be moved large with a small rotational quantity. The cursor is moved instantaneously by using the 2nd micro track ball 7, when the movement quantity is large and when the movement quantity is small, the cursor is moved accurately by operating the 1st micro track ball 6.</p> |
