Claims

[Claims for Utility Model Registration] (1) A winding stem is formed with a plurality of flanges at different intervals, and a positioning lever is attached to two adjacent flanges among the plurality of flanges.
By operating the winding stem and selectively moving the positioning lever between the flanges at different intervals, the rotation direction and amount of rotation are given to the regulating lever body, and the movement of the winding stem is controlled. A clock switching mechanism characterized by providing moderation. (2) A regulation switch lever that electrically stops the rotation of the motor in the regulation lever body, a regulation lever that brakes one of the gear trains that moves the pointer, a movement lever that moves the wheel, and the positioning lever. 2. The switching mechanism for a timepiece according to claim 1, further comprising: a spring for applying a rotational force to bias the regulating lever body; (3) A switching mechanism for a timepiece according to claim 1, characterized in that a forced movement lever capable of forcibly changing the position of the positioning lever irrespective of winding stem operation is integrally formed in a part of the positioning lever. . (4) Claim 1 characterized in that the positioning lever engages with the collar at a plurality of positions sandwiching the center of the winding stem.
Switching mechanism of the clock described. (5) Forming multiple recesses with different valley diameters on the winding stem,
The positioning lever is selectively engaged with one of the plurality of recesses by operating the winding stem, thereby imparting a rotation direction and amount of rotation to the regulating lever body, and moderating the movement of the winding stem. Clock switching mechanism.
