<p>PROBLEM TO BE SOLVED: To obviate a curl of paper such as an envelope, a postcard and an OHP sheet, etc., and a paper jam without incurring an increase in the number of part items and any enlargement of a device itself. SOLUTION: If paper 19 is not a preset paper size, it is conveyed to a paper turnover paper discharge roller 13 by way of a paper discharge roller 10, a paper discharge directional changeover plate 14 and a paper discharge part 11, and it is turned over and discharged by this paper turnover-paper discharge roller 13. Conversely, if the paper 19 is the preset paper size, a paper discharge part-combined paper stacker 12 is rotated by a stepping motor 16 and two driving gears 17 and 18 and thereby it is made into a state of being opened. The paper discharge directional changeover plate 14 performs its changeover operation in linkage with this rotational operation, whereby a paper stacker on-off detecting sensor 15 detects an opening state in the paper discharge part combined paper stacker 12. Subsequently the paper 19 passes through the paper discharge roller 10 and the paper discharge directional changeover plate 14 and it is discharged intact to the paper discharge part-combined paper stacker 12 and stacked in piles.</p> |
