ABSTRACT:
A liquid supplying device has a housing with a connecting portion to which a connector of an endoscope is connected. A lamp, an air pump and a liquid supply tank are arranged in the housing. The pump is connected to the connecting portion and the tank through a pipe. The tank is connected to the connecting portion through a pipe. A switching mechanism is connected to the pipes. A selector valve is connected to the pipe at a position between the pump and the tank. A control circuit is connected to the lamp and pump, and a light source switch is connected to the control circuit. When the switch is closed, the circuit drives the lamp and pump and switches the selector valve to a first position for blocking the pipe, thereby preventing supply of the liquid to the endoscope. When the switch is open, the circuit switches the selector valve to a second position for communicating the pipe. If the switching mechanism is operated under this condition, the liquid is supplied to the endoscope through the pipe.
