摘要：
Pulses of such frequency that an electromagnetic drive device does not operate in response thereto are produced by a pulse generating circuit. While these pulse are being applied to the electromagnetic drive device, the voltage of an electrical power source in the real load running state is detected by a battery checking circuit.
