Abstract

PURPOSE:To perform paper sheet discharge in a good condition in a sorter of a duplicating machine and the like by forming one of paired paper sheet discharge rollers in a shape with greater diameter at both ends than at the center and by bringing the other roller into contact with the central part of the former roller. CONSTITUTION:One roller 6 for paper sheet discharge is formed with greater diameter at both ends than at the center where the other roller 7 for paper sheet discharge is in contact. On the side to the paper sheet discharge rollers of a guide member 9 are formed lugs 9a's at specified intervals. These lugs 9a's are located between each of the pairs of rollers 6 and 7 so that a paper sheet to be passed between the rollers 6 and 7 is brought into contact with the paper sheet discharge roller 6. Accordingly, the paper sheet passed between the paper sheet discharge rollers 6 and 7 is discharged in a corrugated condition, which makes the Clark rigidity of the paper sheet greater, adding to the paper sheet discharging force by the paper sheet discharge roller 6 in addition to the effect of copying paper sheet contact to the paper sheet discharge roller 6 caused by the guide member 9. Thus, copying paper sheets are discharged in a good condition into the bin.
