Claims

[Scope of utility model registration request]

A feed roller with a length approximately equivalent to the width of the paper is exposed through an opening provided in one of the paper guides in a part of the paper conveyance path formed by a pair of paper guides facing each other, and the other A pinch roller shorter than the length of the feed roller is brought into contact with the approximate center of the feed roller through an opening provided in the paper guide, and a portion of the other paper guide facing at least both sides of the feed roller is placed in contact with the center of the feed roller. Formed to protrude toward the feed roller side,
The protruding portion is arranged close to the circumferential surface of the feed roller, and the center of the sheet to be conveyed is conveyed while being pinched by the feed roller and the pinch roller, and at least both sides of the sheet are conveyed by the protruding portion. A paper conveyance structure characterized in that the paper is bent to contact the feed roller, and both sides of the paper are conveyed by friction between the feed roller and the paper.
