DRIVING-FORCE TRANSMITTING MECHANISM OF CLOCK WITH EXPOSED ELECTRONIC CLOCK HANDS OF FLOWER CLOCK AND THE LIKE

摘要

PROBLEM TO BE SOLVED: To provide a mechanism that prevents a power transmitting mechanism from malfunctioning even when a hand is stopped by a foreign object. SOLUTION: A spring 16 (23) for slip is fitted to at least one of a minute hand shaft 8 and a second hand shaft 12, a pressure adjustment nut 17 (24) for adjusting the pressure of the spring is fixed to a shaft, mechanism 14 and 15 (22) for transferring the rotation of a motor to the spring are provided, and the rotation of the motor is transmitted to the shaft through the spring. More specifically, a power transmitting system to the hand of a clock is provided with a slip mechanism, thus allowing the slip mechanism to slip, and preventing a power transmitting device from being damaged, even when the hand is stopped by a foreign matter.
