Title: CLOCK INTERLOCKING APPARATUS
Abstract:
Provided is a clock interlocking apparatus capable of stopping a subordinate hand without load application in a state in which the rotation of an hour hand or minute hand is maintained and of smoothly moving the stopped subordinate hand to a position corresponding to the hour hand or minute hand. An interlocking means 2 is configured from an end cam comprising a driving part 3 and a subordinate part 4. Bringing a roller 3a into contact with a holding part b and holding the same makes it possible to transfer the torque of a minute hand β to a subordinate hand 1. It is possible to cut off the torque from the minute hand β and stop the subordinate hand 1 by separating the driving part 3 and subordinate part 4 so as to separate the roller 3a from the holding part b and a cam surface c. After the subordinate hand 1 has stopped, it is possible to move the subordinate hand 1 to a position corresponding to the minute hand β by bringing the driving part 3 and subordinate part 4 close together and causing the roller 3a to come into contact with the cam surface c.
