<P>PROBLEM TO BE SOLVED: To provide a safety mechanism capable of starting only a striking mechanism in the case of being able to execute the cycle of the striking mechanism completely. <P>SOLUTION: A timepiece includes a movement, a mechanism 750 for controlling the power reserve of driving means 120 having an arbor 751 showing torque whose angular position can be used, a striking mechanism controlled by a striking mechanism control mechanism, and a locking lever 771 for locking the movement. The timepiece includes a selective stop mechanism 760 by available driving torque in the driving means 120, and the selective stop mechanism 760 controls an isolation vehicle set 770 for controlling the position of the locking lever 771, releases or prevents the movement of a striking mechanism control rod linkage, and manages available torque on the basis of whether to limit the whole or partial operation of a striking tool in the striking mechanism by a transfer mechanism 755 configured so as to allow or prevent striking of a flyback lever onto a gong. <P>COPYRIGHT: (C)2013,JPO&INPIT |
