Claims

[Scope of utility model registration request]

A guideline set cam is coaxially and slidably arranged with both wheels, between the first guideline set wheel that is linked to the guideline correction shaft and the first guideline transmission that rotates at a higher speed than the hour hand wheel in conjunction with the clock train. At least two engaging portions are formed on either the first guide set wheel or the guide set cam, and at least two guide molds that can engage with the engaging portions are formed on the other one. Further, at least one of the guide set cam and the first guide gear is configured to allow the guide set cam to mutually rotate by a predetermined amount in the circumferential direction with respect to the first guide gear. a first guide cam mechanism having a first guide cam mechanism formed with a first guide cam mechanism and a first guide cam mechanism having a projection that can be engaged with the first guide cam; A guide mold is formed on either one of a second guide transmission wheel and a second guide set wheel that is arranged coaxially with the second guide transmission wheel and rotates in conjunction with the guide correction shaft, and the other one is formed with a guide mold that engages with the guide mold. a second guide cam mechanism formed with an engaging portion that can be engaged; a movable contact plate that presses and biases the first guide set wheel and the second guide transmission against the guide set cam and the second guide set wheel, respectively; a fixed contact plate arranged and fixed so as to be able to come into contact with and separate from the movable contact plate, the engaging portion of the first guide cam mechanism and either one of the guide type and the engaging portion of the second guide cam mechanism; Either one of the guide molds is formed with an inclined falling surface and a riding surface, and either one near the falling surface of the retaining part of the first guide cam mechanism and near the falling surface of the top of the guide mold. A convex portion is formed on one side, and a concave portion that can be engaged with the convex portion is formed on the other side, and the guide mold of the second guide cam mechanism falls into the shaping portion immediately before reaching the guide setting time, and then, By engaging the convex portion and the recessed portion of the first guide cam mechanism, the protrusion of the first guide cam mechanism and the wall surface of the loose part are maintained in a pressed state, and when the target set time is reached, the first guide cam mechanism is pressed.
An indicator device for a timepiece, characterized in that an indicator cam mechanism indicator die falls into a retaining portion to close the fixed contact plate and the movable contact plate.
