<p>The present invention is provided with two power cords (70, 80), a plurality of processing units, a relay (91), and a control unit (87). The relay (91) enables switching between a conductive state in which the two power cords (70, 80) can mutually and freely provide power and a non-conductive state in which power cannot be provided. The control unit (87) performs the following: storing the priority order of the plurality of processing units; switching the relay (91) from a non-conducive state to a conductive state in a case where power supply via one of the two power cords (70, 80) is turned off; sequentially selecting processing units on the basis of the priority order; and while driving a load device included in the processing unit being selected, from among load devices included in processing units that are not selected, stopping load devices other than a specified load device.</p> |
