<p>PURPOSE:To enable generation of sound of folding of a sheet material or wrinkle to be prevented by providing a means for eliminating the longitudinal corrugation formed on the sheet material. CONSTITUTION:In a sorter H continuously providing to a sheet material discharging port 50 of a copying machine main body M so as to be communicated with the sheet material receiving port 30, conveying roller pairs 3, 4 on the upstream side in the sheet material conveying direction have function for eliminating corrugation of a sheet material S introduced to the sorter H side from the copying machine main body M side. That is, a plurality of (five) lower drive rollers 3 out of the conveying roller pairs 3, 4 are fixed at the specific distance, and driven rollers 4 are brought in pressure-contact with respective upper sides to three driving rollers 3 except for the rollers on both ends by plate springs. On the other hand, bias rollers 4a, 4b to be rotated in the normal rotational direction of the driving rollers 3 are brought in pressure-contact with respective upper sides to two driving rollers 3 on both ends.</p> |
