To maintain a power off state and allow a user to turn the power back on at a timing intended by the user even if a power switch is in a power connection state when the power is turned off without using a location-holding power switch.SOLUTION: An operation control unit 1051 determines the state of a power switch 104. When the result of the determination is in a state of power supply being connected, the operation control unit 1051 puts a power supply circuit 106 into an operational state. When the result of the determination on the operation control unit 1051 is a connected state, if a command to turn off the power supply arrives, a flag setting releasing unit 1052 sets a maintenance flag to a state indicating that the power is turned off by the command. In this case, the operation control unit 1051 controls the power supply circuit 106 to be a non-operating state, and controls the power supply circuit 106 to remain in a non-operating state until the power switch 104 is placed in a shut off state.SELECTED DRAWING: Figure 1 【課題】 位置保持型の電源スイッチを介さずに電源をオフにした場合に、電源スイッチが電源の接続状態にあっても、電源オフ状態を維持し、使用者が意図するタイミングで電源の再投入を行えるようにする。【解決手段】動作制御部１０５１が電源スイッチ１０４の状態を判別し、判別結果が電源の接続状態である場合に、動作制御部１０５が電源供給回路１０６を動作状態にする。動作制御部１０５１での判別結果が接続状態である場合に、電源をオフにすることを指示するコマンドが到来すると、フラグ設定解除部１０５２が、維持フラグをコマンドによる電源オフであることを示す状態に設定する。この場合に、動作制御部１０５１は、電源供給回路１０６が非動作状態となるように制御し、電源スイッチ１０４が遮断状態にされるまで、電源供給回路１０６の非動作状態を維持するように制御する。【選択図】図１
