Abstract
An endoscope system comprises an endoscope provided with passages through which air and water are supplied and sucked and pumps for conducting air and water through the corresponding passages. The control section of the endoscope is provided with switches for generating electrical signals to freely preset the flow rates of air and water. Tubes for connecting pumps to the air passages are provided with valves for controlling the flow rates of air and water. The valves are opened by a servo motor driven by a servo motor drive circuit in accordance with the signal levers of the electrical signals issued from the switches.
