ABSTRACT:
An endoscope apparatus comprises an endoscope body in which an air supply pipe and a water supply pipe are included, and an air supply unit connected to the endoscope body. The endoscope apparatus includes an air supply switch and a water supply switch arranged in an operating section, and a drive signal generator being adapted to receive output signals from these switches, an air supply pump connected to the air supply pipe, a water supply pump connected via a water vessel to the water supply pipe and having an output higher than the air supply pump. The air supply pump is driven responsive to the drive signal from the drive signal generator to achieve normal air supply for a time period during which the air supply switch is closed. The water supply pump is driven to perform water supply for a first predetermined time period starting from the instant when the water supply switch is closed, and the air supply pump is again driven to achieve water removing air supply for a second predetermined time period after the finish of the first predetermined time period.
