Zusammenfassung:	A backup controller which is capable of suppressing an unintended operation performed by a motor which rotates in both of a normal rotation direction and a reverse rotation direction is provided. The control unit of the backup controller activates the second relay and the backup circuit in a case where a state in which the motor is rotating in the first direction even though the first relay is not activated is transmitted from the monitoring unit. Further, the control unit activates the first relay and the backup circuit in a case where a state in which the motor is rotating in the second direction even though the second relay is not activated is transmitted from the monitoring unit.
