A hardware circuit (403) outputs different output signals for a case where an operation performed on an operation switch (402) continues for longer than a threshold time and for the other case. An operation detecting CPU (404) outputs different output signals for a case where an operation performed on the operation switch (402) is detected and for the other case. A signal generating unit (405) inputs, to a power control unit (401), a control signal for switching a power supply mode to an off mode, at the following timings: when the hardware circuit (403) outputs an output signal different from the output signal output in the case where the operation continues for longer than the threshold time, and the operation detecting CPU (404) outputs the output signal output in the case where the operation is detected; and when the hardware circuit (403) outputs the output signal output in the case where the operation continues for longer than the threshold time, and the operation detecting CPU (404) outputs an output signal different from the output signal output in the case where the operation is detected. |
