Abstract

PURPOSE:To conduct time correction accurately and smplify the mechanism and operation by advancing watch hands according to a unit of the time shown by a selected watch hand which should be corrected by steps that are integer times of the unit. CONSTITUTION:The operation signal from a selection switch SW2 is given to a 3-bit shift resistor 4, and its content is shifted by one bit. In each output from the resistor 4, the second bit output is taken out as a second hand selection signal T1 that selects the second hand for correction, and the third bit output is taken out as an hour hand selection signal T2 that selects the hour hand for correction. The operation signal of SW2 is given to FF14, and its output is given to a drive pulse control circuit 19 through an OR circuit 18. The circuit 19 outputs drive pulses phi1 and phi2 alternately according to the output of the circuit 18, and they are given to a pulse motor 20. Then, the minute hand is advanced in steps by the rotation of the rotor 20b of the motor 20. The hour hand is advanced following the minute hand through a train of wheels mechanism.
