PURPOSE:To prevent paper from being irregularly moved, by winding and bond- ing a sheet on the peripheral surface of a shaft along its total circumference and conjoining both the ends of the sheet to each other so that the joint constitutes at least one spiral line. CONSTITUTION:A slender sheet 22 is wound and bonded on the peripheral surface of a shaft 11 so that the joint 23 of the sheet is spiral. Since a part of the joint 23 is always in contact with moved paper not shown in the drawing, the moving force applied to the paper is independent of the rotation of the paper feed roller so that the force is constant. For that reason, the paper is moved non-irregularly or stably. |
