RADIO COMMUNICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a radio communication device that makes its battery charged simply and easily, and that can transmit and receive individual information without replacement work of the battery due to battery consumption.SOLUTION: A radio communication device comprises a plurality of antenna circuits and a plurality of batteries which are electrically connected to the plurality of antenna circuits via respective switches. The plurality of batteries are electrically connected to the different circuits respectively. The plurality of antenna circuits receive radio waves, and thus the plurality of batteries electrically connected to the plurality of antenna circuits are charged. At least one of the plurality of antenna circuits is configured to receive a radio wave with a different frequency.
