Abstract: Device for detaching a copy sheet from the photoconductive drum of an electrophotographic copying machine, wherein the drum has a radial protuberance to which the leading edge of the copy sheet is held by electrostatic attraction and wherein a pick off finger is fixedly mounted adjacent the periphery of the drum at such a distance from the periphery to engage the drum, during its rotation, only in correspondence with the protuberance, so as to detach the copy sheet from the drum.

Abstract: An improved device for fixing in position and covering original documents on the exposure plane of a reprographic machine which comprises a cover for fixing and covering the documents and an actuating arm for the cover, both movable between open and closed positions. The actuating arm is pivoted on the frame of the machine and is coupled by elastic means to the cover. The elastic means urges the cover towards its closed position and produces pressure by the cover on the original document when the arm is in its closed position. A latch mechanism is provided for holding the arm in its closed position and is releasable for allowing the arm and the cover to move from their closed to their open positions.
