ABSTRACT:
A belt feeding device including a plurality of belt feeding rolls, a belt wrapped around the rolls, and at least a pair of guide members each having an edge guide surface against which either side edge of the belt abuts in crosswise movement of the belt. The outer circumferential surface of each roll is formed with a plurality of ring-shaped slits axially spaced a distance w from each other, each of the slits having a depth h and a width m. The values of h, m, and w are set so that a load to an axial displacement of the belt wrapped around the rolls at a position of each guide member becomes 80 N/mm or less. Accordingly, an edge force acting between either side edge of the belt and the corresponding guide member against which the side edge of the belt abuts can be reduced to 15N or less.
