ABSTRACT:
A shaft portion of a retard roller is supported by a pair of supporting members so that the retard roller can be assuredly supported and easily detached. One of the pair of supporting members is provided so as to be movable in the axial direction of the shaft portion. By moving the movable supporting member in a direction of separating from the shaft portion, the retard roller can be detached. A regulation device regulates movement of the movable supporting member in the direction of separating from the shaft portion at a position where the pair of supporting members engage with the shaft portion and is provided on a guide cover for blocking an opening for mounting/detaching the retard roller.
