Document Type and Number:
Japanese Patent JP3931126
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a push button switch unit with conditions of durability, economical performance, etc. required as a push button switch for attaching on a game machine.
SOLUTION: A longitudinally movable member 22 is supported in a cylindrical shape part 21 formed in a surface plate 20. A push button 23 is crowned over the upper end part of the longitudinally movable member 22. A printed circuit board 30 on which an optical sensor 31 comprising a light projector and a light interceptor and a connector 33 are set is fixed on the back side of the surface plate 20. A bearing part 24 and a spring holder 25 are formed on the lower end part of the cylindrical shape part. The longitudinally movable part is upward energized by elasticity of the spring 26b set in the spring holder 25 to elastically project the push button 23 on the surface plate 20 and a light intercepting plate 29 to cross the optical axis of the optical sensor by longitudinal motion is set on the longitudinally movable member 22. An axis part slidably dangling in the bearing part 24 is formed on the lower end part of the longitudinally movable part and, further, a means to limit longitudinally moving width of the longitudinally movable member is provided.
