  • Patent number: 4113373
    Abstract: A copying apparatus is disclosed wherein an original is scanned by a light beam which is then transmitted along a path to the photosensitive surface of an imaging drum. A pair of baffles is arranged symmetrically relative to the aforementioned path and a motion-transmitting arrangement is provided, which is controlled from outside the copying apparatus and which serves to synchronously pivot the baffles into and out of the path to thereby control the amount of light which reaches the photosensitive surface of the drum.
