Zusammenfassung: | PROBLEM TO BE SOLVED: To satisfactorily feed one sheet as well as a sheet bundle consisting of a plurality of sheets without performing troublesome operation for adjusting the positions of feeding rollers.SOLUTION: Feeding rollers 9 are disposed at both sides in a width direction of a handling member 3A only below a sheet bundle to be conveyed. The feeding rollers 9 are disposed so that the top levels of the outer peripheral surfaces are lower than the lowest level of an outer peripheral surface of a paper feeding roller 5. Thus, by adjusting the handling member 3A to a position where the handling member 3A comes into pressure contact with the paper feeding roller 5, sheets can be separately fed one by one by the handling member 3A and the paper feeding roller 5 without being sandwiched between the feeding roller 5 and the feeding rollers 9. On the other hand, by adjusting the handling member 3A to a position where the handling member 3A is separated from the paper feeding roller 5, sheet bundles separately fed by the handling member 3A and the paper feeding roller 5 can be conveyed one by one to the downstream side while being sandwiched between the paper feeding roller 5 and the feeding rollers 9.
【課題】給送ローラの位置を調整するための面倒な操作をすることなく、1枚の用紙でも複数枚から成る用紙束でも良好に給送することができるようにする。【解決手段】捌き部材3Aの幅方向の両側で、搬送される用紙束の下方にのみ給送ローラ9を配置し、かつ、給送ローラ9をその外周面の最上位が給紙ローラ5の外周面の最下位よりも低くなるように配置する。これにより、捌き部材3Aを給紙ローラ5に圧接する位置に調整することにより、用紙が給紙ローラ5と給送ローラ9とに挟まれることなく、捌き部材3Aと給紙ローラ5とにより用紙を1枚ずつ分離給送できるようにする一方で、捌き部材3Aを給紙ローラ5から離間した位置に調整することにより、捌き部材3Aと給紙ローラ5とにより分離給送された用紙束を給紙ローラ5と給送ローラ9とにより挟んで1部ずつスムーズに下流側へと搬送できるようにする。【選択図】図2 |
