Summary:PROBLEM TO BE SOLVED: To reduce power consumption of an apparatus without changing a circuit configuration or a component.SOLUTION: A first power supply module 10 outputs a first voltage Vosufficient to start a relay 210. A second power supply module 20 outputs a second voltage Vothat is a voltage of not more than the first voltage Voand that is a voltage for keeping a starting state of the relay 210 as a starting state of the relay 210. A control module 40 controls the first power supply module 10 or the second power supply module 20 through a switching circuit 30 so as to be connected with the relay 210.
