Abstract

PURPOSE: To make direct use of a driving mechanism performing intermittent motion and yet enable the hands to be continuously driven by providing a transmission means including an elastic coupling member, transmitting member and speed control means.
CONSTITUTION: A rotor consisting of a permanent magnet 11a and a rotor pinion 11 makes 1 turn at 2 steps in 2 seconds by the driving signal of 1 Hz divided down from a crystal oscillator. When the rotor pinion 11 is moved 180° instantaneously by a magnetized stator 20, the 6th wheel 12a intermeshed with this also moves by the angle corresponding to a gear tooth ratio. The 6th pinion 12 connected by a spring 12c produces a time lag owing to the inertial resistance of the inertial mass 13b added to the 5th wheel 13a intermeshed with the 6th pinion 12 and catches up the initial position with respect to the 6th wheel 12a after 1 second. At this time, the driving current again flows in the coil 19 and the rotor pinion 11 again moves by 180°, then the 6th wheel 12a intermeshed with this again goes ahead of the 6th pinion 12 and from this point on the action that the 6th pinion 12 catches up after 1 second is repeated
