In an endoscope apparatus, an air/water switch (15) that is provided in an operating section (9) of an endoscope (5) each generate an air feed on/off signal and a suction on/off signal, and air feed flow and suction flow signals that are responsive to the amount of depression of each of the switches, these signals being sent to a signal processing circuit (33). The signal processing circuit (33) controls a air/water feed control valve 40 and a suction force control valve 50, so as to control air/water feed flow and suction flow, a flow display being made by an indicator (65) on the screen (63) of a TV monitor (35).
