Abstract
A feeding device for a printer having a combination of at least one feeding roller with an opposing pinch roller both upstream and downstream, in the feed direction, of a print position. The upstream and downstream side paper feeding rollers are made from metal and the upstream and downstream pinch rollers are made of a elastic material. The upstream and downstream side paper feeding rollers feed a paper sandwiched between the feeding rollers and opposing pinch rollers. The nip pressure on the downstream side is slightly stronger than the nip pressure on the upstream side so that the feed rate is slightly higher at the downstream side than at the upstream side. As a result, the paper is tant as it moves past the print position. Further, the paper is accurately positioned for each line, even after the paper has cleared than nip of the upstream side paper feeding and pinch rollers.
