Abstract

An endoscope light source device comprises a light source device body and a connector receptacle rotatably set therein. The connector receptacle is provided with a central through hole for receiving a light guide and cylindrical holes penetrated by contact pins projecting from a base of the connector receptacle. The control pins are connected to the leads extending through the connector receptacle. The leads are connected to signal lines coupled to the signal-generating circuit provided in the light source device body. An electrical connection mechanism is mounted on the signal lines or provided between the respective signal lines and leads to ensure electrical connection between the signal lines and leads. An air-conducting passage is provided in a connection conduit formed in the connector receptacle for communication with the air conducting connection tubes. A fluid-conducting mechanism is provided between the air-conducting-connection tubes and air-conducting passage to ensure communication therebetween, regardless of the rotated position of the connector receptacle. Provision of the rotatable connector receptacle, electrical connection mechanism and fluid-conducting mechanism …
