ABSTRACT:
A control mechanism for use in a photoelectrostatic copying machine utilizing a roll of recording medium as a source of material on which an image of the original to be copied is reproduced, which control mechanism controls the sequence of operation of various operating elements of the copying machine. The control mechanism for this purpose utilizes a rotatable cam assembly which, during rotation thereof through first and second predetermined angles, actuates first and second microswitches, respectively, which are electrically coupled to the feeder mechanism, illumination device and electrostatic charger and the drive unit for moving a transparent support structure for support of the original to be copied thereon. A third microswitch electrically coupled to the cutter unit may be actuated by either the cam assemby or an operating member adjustably carried by either of the transparent support structure and illumination device.
