Abstract
PURPOSE:To prevent a contact load from adversely affecting an escapement drive mechanism by a simple construction by controlling a contact opening and closing rod by the rotary force of drive gears for watch and gear for winding a hair spring. CONSTITUTION:When a third gear 13 is rotated at one revolution by a hair spring 10, the driven rod 14 of the gear 13 urges an operating rod 12. Thus, the contact bending end 19 of a spring contact 18 is separated from the rod 12 to cause the contact to close to thereby rotate a winding motor 1 so as to wind up the spring 10. Then, the rod 12 is urged through a sector window 11 of a drive gear 5 rotated cooperatively with the motor 1 to cause the end 19 to be engaged in pushed up state by the rod 12 to thereby open the contact to thus complete the winding up of the spring 10 and to stop the motor 1. Accordingly, it can simplify the construction of the contact device, which does not need cam or the like and does not effect the contact load to the escapement drive mechanism of an escape wheel side having less torque.
