Zusammenfassung:	PROBLEM TO BE SOLVED: To make stoppable the supply of a power to any unnecessary load with a simple constitution in a power saving mode. SOLUTION: The collector of a transistor Tr2 which is turned on/off synchronously with power supply to a fan 24 is connected with the base of a bi-polar transistor Tr3 constituting a rush current control circuit 22 for limiting rush current to a load 50. When power supply to the fan 24 is stopped, the transistor Tr2 is turned off, and the bi-polar transistor Tr3 is turned off according to this state so that the power supply to the load 50 can be stopped. On the other hand, when the power supply to the fan 24 is started, the transistor Tr2 is turned on, and the bi-polar transistor Tr3 is turned on according to this state so that the power supply to the load 50 can be started. A control part 52 can control the power supply to the load 50 only by outputting a driving signal to the fan 24.
