<p>PURPOSE:To prevent the occurrence of skew of a document by running a feed belt around and between a fulcrum roller and a moving roller and mounting a torque limiter on the moving roller. CONSTITUTION:When a fulcrum roller 25 is rotated in a counterclockwise direction, the rotation is transmitted to a moving roller 16 through a rubber belt 27. Since the moving roller 16 incorporates a torque limiter 24, when a rotation force is transmitted from the rubber belt 27, torque is generated at a torque limiter 24. A force obtained by dividing torque with the radius of the moving roller 16 is generated at a contact between the moving roller 16 and the rubber belt 27. As a result, the moving roller 16 is rotated in a counterclockwise direction around the shaft 21 of the fulcrum roller 25 serving as a fulcrum. In this case, since the moving roller 16 is raised without inclination and the upper side of the rubber belt 27 is brought into contact with a document, the feed of paper sheets free from skew is executed through rotation of the rubber belt 27.</p> |
