<p>PURPOSE:To prevent a cursor and display characters from going to difficult to be observed by displaying the cursor on a display screen only when a point coordinate input part is grasped to select one of plural displayed contents. CONSTITUTION:When an operator grasps the point coordinate input part in order to move the cursor to try to select and input one item out of the displayed items, an input operation mode selecting switch 3 is turned on and the ON state is inputted to a controlling microcomputer 46. Consequently, the computer 46 displays the cursor on the display screen 21. When the operator moves the point coordinate input part manually along a desk face, the X-direction rotation and Y-direction rotation of a rotor are respectively transmitted to an X-direction roll 48 and a Y-direction roll 39. Consequently, a voltage level on the intermediate point between variable resistors 40, 41 is changed and converted into a signal and the signal is inputted to the computer 46. The computer 46 displays an image on the screen 21 in accordance with the moving direction and the moving distance.</p> |
