Claims

[Scope of utility model registration request]

(1) A time signal clock that emits an alarm sound on the hour has at least one cam protrusion in which a first inclined surface is formed in the forward rotation direction and a vertical wall is formed in the reverse rotation direction, and the clock train is connected to the clock train. A cam wheel that can rotate once per hour in conjunction with a cam wheel, which is rotatably supported on a receiving plate, and whose sliding end is elastically biased by an elastic member that allows it to slide against the outer periphery of the cam wheel. , a swinging lever whose other end is arranged so as to be able to actuate a switch device that is placed close to it, and a switch device that can turn on and off a time signal generator in conjunction with the swinging operation of the swinging lever. The cam wheel has a cam peripheral surface portion on one plane of the cam protrusion [7, and a second inclined surface formed by cutting out a vertical wall surface having a predetermined width from the cam axle surface. A cam for a timepiece, characterized in that a groove is provided, and when the cam wheel is reversed, the sliding end of the rocking lever rides up the second slope, thereby making it possible to reverse the cam wheel. Contact mechanism.

(2) Utility model registration In the mechanism described in claim 1, the groove portion formed in the cam protrusion has a second inclined surface that descends in the forward rotation direction of the cam wheel and is adjacent to a second inclined surface that descends in the reverse rotation direction of the cam wheel. 3
A cam contact mechanism for a timepiece, comprising an inclined surface and a flat surface adjacent to the third inclined surface and having a thickness thinner than the thickness of the cam protrusion.
