ABSTRACT:
An image reading apparatus has a read roller having a flexible shaft a deformation of which in a particular direction is prevented so as to prevent a displacement of the read roller. The image reading apparatus reads an image on an original sheet while the original sheet is fed along a reading surface. A roller is pressed against the reading surface so that the original sheet interposed between the roller and the reading surface is fed by a rotation of the roller. A shaft extends from opposite ends of the roller so as to support the roller and transmit a rotational force to the roller. The shaft is rotatably supported, and is capable of being elastically deformed. A deformation of the shaft in a direction perpendicular to a rotational axis of the shaft and parallel to the reading surface is restricted by projecting members contacting the shaft on each side of the roller.
