An endoscope light source apparatus which can feed an illuminating light adapted to a scope provided with a frame sequential type imaging device, a scope provided with a color mosaic type imaging device and a fiber scope has a light source lamp which can emit the illuminating light. A filter which can transmit the illuminating light is interposed in the light path connecting the light source lamp with the entrance end surface of a light guide capable of feeding the illuminating light to the scope and is provided within a cassette which is inserted through an inserting aperture provided on a housing containing the light source apparatus.

Endoscope light source apparatus

The endoscope light source apparatus of this invention has a light source for emitting a white color light as an illuminating light and a connecting part connectable with the light guide of the endoscope. Reflecting members are movably provided in the light path connecting the light source and the connecting part, and switch the light path between a light path through which the illuminating light adapted to an endoscope provided with a frame sequential type imaging device can be made to enter a filter which can sequentially transmit it and a light path which can avoid the filter.
