Abstract
PURPOSE: To enable the correction of time with little delay in actual measurement without increasing the consumed current by controlling an ordinary driving output generating circuit and a compensating driving output generating circuit by a frequency divider with a small ratio of frequency division.
CONSTITUTION: When a correcting input is applied from a normal rotation input switch SW1, a frequency dividing circuit 2 starts a counter action for correcting period counting by a normal rotation correcting period controlling circuit 5, while bringing into a state of prohibition the ordinary driving output generating circuit 31 driven through the intermediary of the 2nd frequency dividing circuit 23 having small number of elements than the circuit 2 and a simple constitution, and the driving output during the period of correction is made to be read in by the compensating driving output generating circuit 32. And, by the delayed compensation output read in the circuit 32, the driving circuit 4 is driven at the time of completion of the correction. By using the frequency dividing circuit having a simple constitution and a small ratio of frequency division also when the reverse rotation is corrected, the correction of the time is performed with small delay in actual measurement and without increasing the consumed current.
