Abstract
PURPOSE: To improve the quality of design with the constitution of a time corrector simplified by dividing the continuous operation period of a correction switch in terms of time and then by making the advance correction of a pulse motor by generating a different-speed correction pulse in each divided period.
CONSTITUTION: Pulse motor 19 is advanced by normal clocking signal (ϕ), but when a small time correction is needed, the shorttime setting operation of correction switch 6' is repeated to send correction signal Ps of a single-shot pulse from terminal B of correction pulse generating circuit 20. In case of a large correction, correction switch 6' is held in a set state to make a fast-feed correction right before a desired value by correction signal Ps of 32Hz, and the remaining correction is made by correction signal Ps of a single-shot pulse through shorttime setting operation. This constitution realizes the thinning of an electronic watch, the improvement of design and the reduction in cost.
