A signal generator (18) is provided on an endoscope (11) for selectively generating an air feed instruction signal, water feed instruction signal, suction instruction signal, air-gas exchange instruction signal and so on. The instruction signal of the signal generator is multiplexed by a multiplexer (19) and sent as one multiplexed signal to a demultiplexer (30) in a light source unit (29) through one transmission path (20). The multiplexed signal is demultiplexed by the demultiplexer and thus a valve device (33) is controlled so as to effect air feed, water feed, suction and air-gas exchange operations.
