PROBLEM TO BE SOLVED: To provide a power feeder apparatus for feeding power via vibration without input/output terminal. SOLUTION: When a drive circuit 11 receives power from a power supply 10 and generates a drive signal V in a power feeder apparatus A1, an actuator 12 vibrates, and this vibration is transmitted to a converter 21 of a power receiving apparatus B1 via vibration transmitting members 14, 20. The converter 21 is provided with a piezoelectric element to convert the vibration into voltage, namely an electromotive voltage Vg. The electromotive voltage Vg is rectified with a rectifier circuit 23 and a large capacitance capacitor 24 is charged with a rectified voltage. A clock circuit 25 measures the time, by receiving the power from the large capacitance capacitor 24. |
