Abstract

PURPOSE: To reduce the required time for correction, by enabling the correction of time difference in pure electrical method with a simple switch constitution, by using forward and reverse driving pulse motor.
CONSTITUTION: The circuit consists of the time standard oscillation circuit 101, frequency dividing circuit 102, conversion circuit for correction pulse generation 109, count circuit 116, drive circuit 105, forward and reverse rotation pulse motor 106, wheel set 107, indication and display set 108, and time difference switches 113 and 114, and it provides the time difference correction function of pointers. In this case, at forward time difference correction, the count circuit 116 makes the number of pulses of correction controlled for count with the or equal to the number of correction pulses controlled for the count at reverse time difference correction, and the number of correction pulses at forward time difference correction is the sum of the unit correction pulse number and the stationary drive pulse number produced within the correction time, and the number of correction pulses at the reverse time difference correction is the difference between the unit correction pulse number and the stationary drive pulse number within correction time.
