PROBLEM TO BE SOLVED: To provide an infrared communication system which enables mutual communication by receiving an infrared signal transmitted from infrared communication equipment located at a fixed position to the other pieces of infrared communication equipment in plural different azimuths. SOLUTION: A rotary reflection mirror 1 is attached on the ceiling, and at the optimum rotating speed according to a transmission frame length, the rotary reflection mirror 1 is rotated. Besides, the rotary reflection mirror 1 is composed of plural blade-shaped reflection mirrors, and since the respective blade-shaped reflection mirrors have different angles onto horizontal and vertical planes, the incident light of infrared rays is reflected in multiple azimuths so that the communication among respective pieces of infrared transmission/ reception equipment 3-5 can be performed. |
