First Claim
1. A portable terminal apparatus, comprising:
- a power supply;
a power receiving circuit configured to wirelessly receive electric power for charging the power supply;
a first communication circuit configured to transmit and receive information relating to receiving the electric power;
a second communication circuit including a communication antenna, a near field radio communication circuit and a switch arranged between the communication antenna and the near field radio communication circuit; and
a controller configured to control the switch to disconnect the communication antenna from the near field radio communication circuit in response to the first communication circuit receiving the information relating to receiving the electric power.

Abstract
A portable terminal apparatus according to an embodiment includes a power supply and a power receiving circuit that wirelessly receives electric power for charging the power supply. A first communication circuit transmits and receives information relating to receiving the electric power. A second communication circuit includes a communication antenna, a near field radio communication circuit and a switch arranged between the communication antenna and the near field radio communication circuit. The second communication circuit is selectively configured to communicate with a separate terminal device via near field radio communication. A controller controls the switch to disconnect the communication antenna from the near field radio communication circuit in response to the first communication circuit receiving the information relating to receiving the electric power.
