<p><P>PROBLEM TO BE SOLVED: To provide a communication device including a plurality of coil antennas, capable of supplying power according to consumed power in a balanced manner when the consumed power of an operating means connected to each coil antenna is differed. <P>SOLUTION: The communication device includes a first coil antenna for receiving signal transmitted from an external communication device; a first output means which performs a predetermined output by use of a power obtained from the signal received through the first coil antenna; a second coil antenna for receiving signal transmitted from the external communication device; and a second output means which performs a predetermined output by use of a power obtained from the signal received through the second coil antenna, the power being larger than the power supplied to the first output means. At least the opening area of the second coil antenna is larger than the opening area of the first coil antenna, or the number of turns of the second oil antenna is larger than the number of turns of the first coil antenna. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
