ABSTRACT:
The rear edge support rollers which protrude in the U-shaped sheet paths on the upstream side of the sheet feeding direction prevent the rear edge of the sheet from sliding in contact with the path walls and restrain back tensions from working on the main sheet feed roller while the sub-sheet feed rollers which are disposed inside the U-shaped path are imparted with the revolutionary resistances that correspond to the curvatures of the paths so as to reduce the loads which are given to the main sheet feed roller to work in the direction of forwarding the sheet by the rear edge of the sheet thrusting against the outer lateral wall due to the stiffness of the sheet.
