A first power system supplies electric power to a first control circuit. A second power system supplies electric power to a load further on a downstream side than the second power system. A second control circuit receives the supplied electric power from a commercial power supply. In a power saving mode, a path switching section switches an electric power supply path to interrupt the electric power from the second power system to a cooling fan and supply electric power from an electricity storing section to the cooling fan. |
