Abstract
PURPOSE:To save useless paper and to make the handling easy, by making the reproduction of the original picture through the separation of overlapped paper if overlapped delivery is caused, and discharging paper as white paper through the stopping of scanning of an optical system to the remaining paper. CONSTITUTION:If two sheets S1, S2 of paper are fed between a driving roller 32 and a follower roller 32', a rotating load is increased and the paper S1 only in contact with the driving roller 32 is carried. On the other hand, since the follower roller 32' is not rotated, the paper S2 which is in contact with it is stopped, the paper S1 and paper S2 are separated and carried one by one. Thus, a rotating disc 156 interlocked with the roller 32' is stopped and no pulse signal is outputted from a photosensor 157. Overlapped delivery is detected via an overlapped delivery detecting cirduit and a counter, the scanning of the optical system is stopped for a prescribed time, and after the remaining paper is discharged as white paper, the sequence returns to the normal sequence. Thus, useless paper can be saved and the handling can be made easy,
