Abstract
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.
