<p>PROBLEM TO BE SOLVED: To suppress an adverse effect upon a communication device, even if during the operation of the communication device by receiving non-contact power supply, the non-contact power supply is intercepted.SOLUTION: A communication control unit 21, if being in a power supply OFF state in which a first power voltage Vcc is not supplied thereto, is activated by a second power voltage Va when the second power voltage Va is generated in a power supply circuit 24 from reception power from an external device 100 in a non-contact manner. The communication control unit 21, after the activation, determines processing to be executed on the basis of the non-contact communication with the external device 100, so as to switch on a power changeover switch 10 if the processing to be executed is specific processing. When the power changeover switch 10 is switched on, a third power supply voltage Vb is supplied from a backup power supply 6 to the communication control unit 21. This enables the communication control unit 21 to continue operation by the third power supply voltage Vb if the power reception from the external device 100 is intercepted.</p> |
