<p>[PROBLEMS] To solve the problem that installation of an electric device such as a transmitter transmitting a micro wave such as a Bluetooth and an RFID, a transmitter transmitting infrared rays, and a camera for capturing an image requires a high cost. [MEANS FOR SOLVING PROBLEMS] Energy is acquired from a magnetic field generated by current for turning on a fluorescent lamp of an illumination device so as to drive an electric device such as a transmitter transmitting a micro wave such as a Bluetooth and an RFID, a transmitter transmitting infrared rays, and a camera for capturing an image.</p> |
