ABSTRACT:
A conveying roller conveying a paper has a stepped structure with the diameter of portion positioned at the middle in the axial direction of the conveying roller slightly larger than that on opposite sides or ends of the conveying roller. The center in the axial direction of such middle portion almost coincides with the center in the axial direction of a paper-supplying roller positioned upstream of the conveying roller. The promotion of the inclined conveyance of paper resulting from inclined supplying to the conveying roller is prevented, particularly in the case of a one-end standard paper-supplying mode wherein one side end in the direction of the width of paper is regulated by a paper-supplying guide. The middle roller portion is displaced axially toward the side of the paper-supplying guide. The forces of two springs for urging an image-read out device toward the conveying roller to be almost equal to each other. The distance in the axial direction from the center of the middle portion of the conveying roller to the spring disposed on the side opposite to the paper-supplying guide is slightly larger than the distance from such center to the spring disposed on the side of the paper-supplying guide.
