Beschreibung
Zusammenfassung:	A motor control circuit includes a manipulation unit, a control unit that drives a motor in a normal rotation direction or a reverse rotation direction, a catch detecting unit that detects a foreign substance caught in the opening and closing body, a first relay circuit that connects one of terminals of the motor to a power supply when the motor is driven in the normal rotation direction, a second relay circuit that connects the other terminal of the motor to the power supply when the motor is driven in the reverse rotation direction, a switch element that cuts off connection to the power supply when the normal rotation command is fed into the control unit from the manipulation unit, a detection circuit, and a feed circuit.
