In FIG. 6, in order to move the cursor or the like to indicate the coordinates, the pen type operation means 31 is held by hand and tilted in a desired direction and at a desired angle. The inclination of the pen-type operation means 31 is the inclination detection means 3
The inclination angle is detected by 1a and is transmitted from the oscillating means 31d to the processing device 32.

The processing device 32 moves the cursor displayed on the graphic display device in accordance with the tilt angle of the pen type operation means 31, as in the case of the stick shown in the first embodiment. The operator operates the pen-type operation means 31.
