Abstract

PURPOSE:To achieve paper feeding with high accuracy in any environmental conditions and for any paper, by disposing rollers on the upper side of a platen on the downstream side of the platen with respect of a paper-feeding direction, driving the rollers to rotate at a circumferential velocity equal to or greater than that of the platen, thereby bringing a printed part of a paper into contact with discharging rollers by the rollers, and pulling the paper by frictional forces. CONSTITUTION:A paper, whether a slip paper or a continuous form paper, is wrapped around a platen 5, and is passed through the front side of a printing head 7. When the leading end of the paper reaches a middle point between a paper bail 12 and discharging rollers 1, and bail 12 is moved in the direction of an arrow (e) to guide the leading end of the paper to a position between the discharging rollers 1 and auxiliary rollers 2 for discharge. The circumferential velocity Vb of the platen 5 and the circumferential velocity Vc of the discharging rollers 1 are so set that Vc>=Vb, and the paper is bent by an overlap amount (h) of the discharging rollers 1 and the auxiliary rollers 2, with a spacing (i) therebetween in the column direction, so that the paper is brought into contact with the discharging rollers by a restoring force, and the paper is pulled upward by frictional forces. With this construction, it is possible to reduce the degrees of variations in surface frictional coefficients or feeding velocity due to variations in environmental temperature and the like, and to position a printing paper with high accuracy.
