Abstract

PURPOSE: To enable a sheet material to be stably fed by configurating a device in such a way that a portion of a conveyor roller at that section opposite to a conveying reference which corresponds to the edge of the sheet material of small size, is made rotatable independently from the other portion of the conveyor roller in a copying machine and the like.
CONSTITUTION: A driving conveyor roller 23 which is pressed on a conveyor roller 5, is composed of a roller portion 25 which is driven by a driving shaft 24 as an integral part, and of a roller portion 26 which is rotatably free from the shaft 24. And the roller portion 26 is designed to cover the area which includes the edge of a small size but thick fixed form P' that is assumed to be practically used, where the edge is in the opposite side of a conveying reference. In this case, the form P' is under distributed pressure W of the conveying roller 23, but no driving force is transmitted to the roller portion 26 from the shaft 24. Accordingly, the form P' is conveyed with no oblique motion accompanied. On the other hand, when the sheet material of large size is conveyed, conveying force is out of balance at the right and left sides, however, as the form is extensively in touch with roller portion 25, and the amount of unbalance is so negligible as a whole that no oblique motion occurs.
