PURPOSE:To reduce power consumption, and to prevent the generation of heat of the pulse motor by bringing the pulse motor to a non-excitation state when the motor is not turned. CONSTITUTION:The control circuit for the revolution of the pulse motor 1 has a pulse signal generating circuit 3, a decoder circuit 4 and a drive circuit 5, and further has a re-triggerable monostable multivibrator 10 and a gate circuit 11. The coils 6-9 of the motor 1 are excited only when pulse signals are emitted from the pulse signal generating circuit 3, and output pulses are not emitted from the monostable multivibrator 10 and the coils 6-9 of the pulse motor 1 are not all excited when there is no pulse signal, when the pulse motor 1 rests. |
