Abstract
A discharge pressure measuring device is provided with a discharge pressure measuring system that measures a discharge pressure of the air discharged from a discharging end of an air supplying tube provided to an endoscope. The air discharged by the discharging end is directed to a pressure sensing portion of the discharging pressure measuring system through a pipe. A circuitry for obtaining a voltage representing a true discharge pressure based on a voltage output by the discharge pressure measuring member is provided. A positional relationship of the air discharge portion of the pipe with respect to the pressure sensing portion is changeable.
