PROBLEM TO BE SOLVED: To reduce excessive transmitting current by regulating to a suitable current after an infrared transmitter and an infrared receiver are installed by deciding the transmitting current necessary to communicate due to clear relations when the transmitter and the receiver are fixedly installed. SOLUTION: A bathroom apparatus comprises an infrared transmitting means installed on a wall surface in a room and used, and an infrared receiving means disposed to receive an infrared signal from the transmitting means. The transmitting means further has an infrared current regulating means for regulating the infrared transmitting current. Further, the apparatus further comprises a means for compensating the transmitting current in the case a battery voltage drop. Thus, reduction in a communicating performance due to a change in a circumferential environment or a deterioration of an infrared transmitting element or the like is compensated. |
