ABSTRACT:
A light source unit for an endoscope is provided with a number of flash tubes which are caused in turn to emit a light. On an optical path passing through a light-incident surface of a light guide of the endoscope there are arranged, in corresponding relationship to the flash tubes, a number of plane reflecting mirrors which reflect the lights from the flash tubes toward the light-incident surface of the light guide, respectively. The reflecting mirrors are each movable, for example, by a rotary solenoid. This solenoid operates at the time when the light emission from one of the flash tubes is completed. Thus, the solenoid, for the purpose of giving the optical path for a succeeding one of the flash tube, removes from that optical path the reflecting mirror corresponding to said one of the flash discharge tubes.
