Title: Electronic control type mechanical clock
Inventor: HARA TATSUO
IPC: G04C10/00
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To obtain an electronic control type mechanical clock capable of improving start-up performance of a generator(rotor) without disturbing small- sizing of a clock. SOLUTION: A torsion spring 70 for vibrating each wheel 6 to 12 in termination state according to rotation of a square hole wheel 4 is provided. As these static friction turns to kinetic friction by the vibration of each wheel 6 to 12, the friction force of each wheel 6 to 12 is lowered and the transmission efficiency μ of torque in wheel series can be improved and the rotor 13 gearing with the wheel series can surely be started. At this moment, differing from improving the start-up performance of the rotor 13 by increasing the size of a spring 1a, no fear of enlarging clock size exists.
