Abstract
The movement volumes of X and Y to the X axial direction and the Y axial direction and the rotate angle .theta. of the coordinate input device moved on the substrate, are calculated by the input controller. The calculating device outputs instruction signals to the display device to move the cursor displayed on the display device by the movement volumes of X and Y, and rotate the cursor by the rotation angle corresponding to that calculated by the input controller.
