Abrégé
(EN)

Disclosed is a paper feeder for sequentially feeding laminated cutform paper to a record/write portion or the like. Proper sagging of the cutform paper is produced on this side of a paper feeding roller during rotations of the paper feeding roller in an anti-feeding direction, thus adjusting the direction thereof. Subsequently, with rotations of the paper feeding roller in a paper feeding direction, a feed roller is temporarily rotated. The paper feeding roller is caused to exactly pull in the cutform paper without exerting abrupt fluctuations in load on the paper feeding roller and the cutform paper.
