EQUIPMENT WITH COORDINATE INPUT DEVICE

摘要

PROBLEM TO BE SOLVED: To make the equipment small-sized and to improve the operability by forming the operation shaft of a multidirectional detection switch shorter than the radius of curvature of the outer peripheral surface of an operation body. SOLUTION: At the ring-shaped center part of a printed wiring board 14 fitted with ring-shaped conductive rubber 11, the multidimensional detection switch 4 is equipped with the operation shaft 8 which can freely be swung on O' axis to many directions. The tip of the operation shaft 8 is an engagement projection part which is formed spherically and the engagement projection part is loosely fitted in an engagement recessed part 7a in a cylinder part 7 drooped from the internal vertical surface of the operation body 2 with the multidirectional detection switch 4 fitted to the printed wiring board 14. Thus, the tip of the operation shaft 8 is loosely fitted in the cylinder body 7 and then no mutual interference is caused even when the operation shaft 8 which is shorter than the radius of curvature of the spherical surface of the operation body 2 is associated by making sphere the tip of the operation shaft 8 and making its diameter shorter than the internal diameter of the cylinder part 7 of the operation body 2.
