ABSTRACT:
A connector is connected to an endoscope through a universal cord into which a light guide is inserted. A socket is fixed to a housing to receive the connector. A light is emitted from a lamp and, after being reflected by a reflective mirror, is transmitted into a distal end of the light guide which extends from the socket. The lamp is connected through a dimmer circuit to a power source and a relay switch is provided between the lamp and the dimmer circuit. The relay switch is opened and closed by a solenoid which is connected to a power source through a detector which detects whether the connector is received in the socket.
