ABSTRACT:
A microfilm projecting apparatus for projecting an image of a microfilm on a screen and projecting the same on a photoreceptor, the microfilm projecting apparatus including a reflector movably provided between a first position out of an image projecting light path and a second position in the image projecting light path. The image projecting light travels to the screen when the reflector is at the first position. The reflector moves from the first position to the second position along a plane including the reflecting surface thereof and reflects the image projecting light to the photoreceptor at the second position. A detector is arranged for detecting the density of the image by receiving the image projecting light reflected by the reflector while the reflector is moving from the first position to the second position.
