ABSTRACT:
A paper feeding system for a copying apparatus has an auxiliary paper feeding unit which feeds paper to a photocopying member over a longer path than that of a primary paper feeding unit. The paper feeding system is provided with a drawing-out roller for feeding paper from the auxiliary unit to a stand-by position which is provided with a pair of auxiliary paper feeding rollers, for feeding paper from the stand-by position into the copying apparatus, and a detector for detecting paper at the stand-by position. When no paper is detected at the stand-by position, a signal is provided to the drawing-out roller to feed another paper from the auxiliary unit to the stand-by position. The stand-by position is selected so that the length of the paper feeding path from the stand-by position to the photocopying member is about equal to the path from the primary paper feeding unit.
