POWER RECEPTION DEVICE

PROBLEM TO BE SOLVED: To provide a power reception device achieving highly efficient power reception with a simple structure.SOLUTION: According to a state maintenance signal KEEP from an update instruction unit 323, a setting switchover unit 322 determines the sign of a differential value of a power reception signal Ei (potential change rate) dEi/data in a state that a power reception electrode RDi is disconnected from output terminals T1, T2 by a switch unit 321, and according to a determination value Hi of the determination result, generates a control signal Sij to set the switch unit 321 in such a manner that mutual power reception electrodes RDi producing the same signal level of the determination value Hi are connected to the same output terminal T1 or T2.
