ABSTRACT:
Method and apparatus for feeding original and copy sheets in a duplicator having an improved copyboard containing a radiation-transmissive plate adapted to carry superposed thereon the original and copy sheets with the original disposed between the plate and the copy sheet, the copyboard being linearly reciprocatable between a loading station, at which the original and copy sheets may be positioned on the plate, and an exposure station, at which the copy sheet is exposed through the radiation-transmissive plate and the original sheet and is thereafter removed for further processing. At the end of each exposure cycle, the copyboard moves back to the loading station carrying thereon the original sheet for the initiation of a subsequent sequence. Also disclosed are method and apparatus for accurately registering the copy sheet and original sheet on the copyboard and method and apparatus for separating the exposed copy sheet from the original sheet.
