<p>PROBLEM TO BE SOLVED: To provide a plane coordinate input device small in size and thin in thickness by providing a left switch, a right switch and a third switch and providing the combined output the third switch and the left switch, the combined output of the third switch and the right switch and the combined output of the third switch and a coordinate input value. SOLUTION: This plane coordinate input device 1 is provided with a plane coordinate input part 2, the outputs of the left switch 5a and the right switch 3a and the third switch 4a. The combined output of the third switch 4a and the left switch 5a, the combined output of the third switch 4a and the right switch 3a and the combined output of the third switch 4a and the plane coordinate input part 2 are incorporated in the plane coordinate input device 1. The coordinate input part 2 is connected to the mouse input port of a personal computer with a connection cable 7 and a coordinate is outputted. Thus, the device can be made small in size and light in weight.</p> |
