<p>The present invention makes it possible to use an endoscope to which a mechanical valve is applied as an endoscope using a solenoid-valve unit and realize both fluid control modes by one endoscope. In case of an endoscope for opening/closing various conduits, for example, a mechanical suction member (28) is removably set to a catching part (30) provided for a case body (44) of an operation part (10B) and an electrical operation member (29) is set so as to be removable from the catching part (30). The electrical operation member (29) is constituted so as to secure the flow of a fluid in a conduit and has an electrical switch (38). Electrodes (41A, 41B) of the switch (38) are connected to a signal line (43) through a joint (42) and the signal line (43) is connected to a solenoid-valve unit. The same is true for air supply/water supply. Thereby, it is possible to perform fluid control using a solenoid-valve unit instead of a mechanical valve. <IMAGE></p> |
