ABSTRACT:
An apparatus for automatically and incrementally feeding a continuous fan-folded document to be copied having interconnected segments over a bed plate of a flash illumination photocopier for sequentially positioning each document segment on the bed plate. A drive assembly engages and moves the document having a motor supplying motive power to the drive assembly. The motor is coupled to the drive assembly through a clutch that controls the supply of motive power. A brake is coupled to the drive assembly to stop document movement when the clutch is disengaged to position each document segment on the bed plate. A control mechanism automatically engages the clutch and releases the brake to feed a subsequent document segment to the bed plate after a copy run of a given document segment has been completed. Engagement of the clutch and release of the brake is initiated simultaneously with the last flash in the copy of the photocopier illuminating strobe lamps. Subsequently, the control mechanism automatically disengages the clutch and engages the brake when the next document segment is correctly positioned on the bed plate for copying.
