Claim 10:
11. A control device used in a power receiving device that contactlessly receives power from a power transmitting device, the control device comprising:
a processor configured to control a power supply that supplies power to a load based on received power, the received power being received by a power receiver in the power receiving device from the power transmitting device, the processor being programmed to:
determine whether the power receiver has received a first signal having a first frequency and a first duty from the power transmitting device;
determine whether the power receiver has received a second signal from the power transmitting device, the second signal having a second frequency that is different from the first frequency or having a second duty that is different from the first duty;
determine a time length of a reception period during which the power receiver has received the second signal;
in a case of having determined that the time length of the reception period is a first length, specify that an issued communication data issued by the power transmitting device is first communication data; and
in a case of having determined that the time length of the reception period is a second length that is different from the first length, specify that the issued communication data is second communication data that is different from the first communication data.
