Abstract
A copying machine including a first light source for illuminating an original on an original table, a second light source for illuminating a slidefilm, a slide projector having a slidefilm support which supports a slidefilm movably and the second light source, a mirror which is movable to a reflecting position for reflecting the light reflected from the original onto the photosensitive member as well as to a retracted position for allowing the light from the slide projector to be directly projected onto the photosensitive member, a detector for detecting whether the mirror is in the reflecting position or in the retracted position, and a light regulator for regulating power supply to either one of the first light source or the second light source which is selectively put into operation on the basis of the detected result of the detector.
