Claims (1)

[Claims for Utility Model Registration] A pulse generation circuit that outputs a drive pulse train of a constant period, and a gate that switches the supply and cutoff of the drive pulses to the pulse motor by a stop pulse described later and by a go pulse. an encoder that outputs a stop pulse every time the object to be rotationally controlled rotates by a predetermined angle; a first pulse generation circuit that outputs a go pulse after a short period of time after each stop pulse is generated; and a power source for the pulse motor. A first line with a small resistance interposed therebetween and a second line with a large resistance interposed therebetween, which are provided in parallel as supply lines, are connected to the output side of the gate, and the drive pulse is connected to the output side of the gate each time the drive pulse passes. a second pulse generating circuit that operates for a period of 1 to 2 times as long as one cycle of the second pulse generating circuit; A pulse motor drive control circuit for controlling rotation, comprising switching control means for selectively connecting a line of the pulse motor to the pulse motor.
