PURPOSE:To minimize the size of a motor as well as to prevent the oblique feeding of the paper on a sending out roll in a rolled paper feeder for a copying machine and the like by constructing to press a paper between a recording paper roll and a let-out roll by means of a pair of concave and convex blocks for giving a friction resistance. CONSTITUTION:A rolled paper 2 is supplied, passing between a convex block 12 and a concave block 11 of a loading device 10 through a sending out roll 3 and a guide baffle 9. In this course, when passing through the loading device 10, the rolled paper 2 is pushed on a concave-shaped stationary block 11 by the force of a compression spring 13 via the convex-shaped block 12 to receive a friction resistance. Consequently, the pulling force of the sending out roll 3 and the tension of this friction force are added on the rolled paper 2. This construction to give a constant force to the rolled paper 2 permits to prevent the oblique feeding on the sending out roll as well as to minimize the size of the driving motor. |
