<P>PROBLEM TO BE SOLVED: To facilitate the setting and the diagnosis of an electronic device without increasing power consumption, costs, processing loads, and the device size with information leakage prevented. <P>SOLUTION: A power circuit 32 converts AC voltage supplied from an external power 35 into DC voltage. A power reception coil 22 receives power externally by electromagnetic induction coupling. A power reception circuit 23 receives AC power supplied via the power reception coil 22 and converts the AC power into DC power. A transceiver coil 24 transmits and receives data externally by electromagnetic induction coupling. A transmission circuit 25 and a receiving circuit 26 transmit and receive data via the transceiver coil 24. A memory 29 stores the transmitted and received data. Power from the power circuit 32 is supplied to a main function unit 31, the transmission circuit 25, the receiving circuit 26, a controlling unit 27, and the memory 29. Power from the power reception circuit 23 is supplied to the transmission circuit 25, the receiving circuit 26, the controlling unit 27, and the memory 29. <P>COPYRIGHT: (C)2012,JPO&INPIT |
