ABSTRACT:
A control device for a copier of the type loaded with a recyclic document feeder (RDF) and operable in a two-sided copy mode for producing two-sided copies by sequentially stacking one-sided paper sheets and refeeding them for transferring images on the other side thereof. In the two-sided copy mode, side fences provided on an intermediate tray are moved toward and away from each other in matching relation to the paper size. Even when the entry of a paper sheet in and the refeed of a paper sheet from the intermediate tray occur alternately, paper sheets entered the tray can be accurately controlled in position with no regard to the paper size.
