It moves without slipping due to the rising protrusion 14 of the.
Then, when the paper 3 passes between the high friction roller 10 and the pinch roller 2, as shown in FIG.
Since the tip end of the sheet of paper securely bites into the paper 3, the paper 3 comes into close contact with the outer peripheral surface of the high-friction roller 10 and the feeding accuracy of the high-friction roller can be improved.

なっていた。In this respect, in the conventional method of forming protrusions by etching, if the resist is peeled off during etching, the protrusions may disappear or the height may vary, so that the resist remains large until the end. As a result, the top surface of the protrusion has a certain area. For this reason, the projections may not completely cut into the paper, and the paper may be fed at a height midway between the projections, which causes a decrease in feeding accuracy.
