PURPOSE:To eliminate completely the need to bore a hole in a partition wall and to transmit an electric signal from one flank of the partition wall to the other flank by fitting a transmission and a reception part opposite to the partition wall, and composing the transmission part of a photodetection part including a photoelectric converter which senses infrared light and generates a voltage and a transmitting antenna which radiates a modulated carrier wave. CONSTITUTION:The partition wall 1 is made of woody material or building material such as concrete. The transmission part 2 and transmission part 3 are positioned on the opposite surfaces of the partition wall 1. The transmission part 2 consists of a transmission part case 4, photodetection part 5, transmission conversion part 6, and transmitting antenna 7. An electric signal corresponds to specific information generated by an infrared wireless remote controller and a carrier is modulated by said electric signal corresponding to the specific information sent from the photodetection part 5 and supplied to the transmitting antenna 7. Therefore, the antenna 7 radiates a radio wave corresponding to the information of light 11 transmitted by the infrared wireless remote controller. |
