<p>PURPOSE:To properly offset both single sheet output paper and an output paper sheaf discharged into a stacker by providing at least two or more sheet offset means, means for recognizing a single sheet discharge or a sheaf discharge and a means for switching the offset means by the single sheet/sheaf discharge. CONSTITUTION:In the case of discharging output paper to a stacker, for discriminating the predetermined output paper from the other paper, the output paper is offset and discharged into the stacker. A single sheet of paper or an output paper sheaf, discharged from an image forming device or the like, is offset and discharged into the stacker by a discharge means. The output paper is recognized for whether its discharge is single sheet/sheaf discharge by a recognizing means, and the single sheet/sheaf output paper is offset and discharged into the stacker with a proper offset means by switching a plurality of the offset means. In this way, even when the discharged output paper is a single sheet r a sheaf, the output paper, surely offset, can be stably discharged into the stacker.</p> |
