Paper transport device for a recorder

摘要

A paper transport device for a recorder such as an ink jet printer has a support for clean paper, guidance rollers, and a drive device. The transport devices moves the paper from the paper support past a printing head. In order to exert a symmetrical pull on the paper and simultaneously to make substantially the entire width of the paper available for writing thereon, the paper transport device has at least two rollers mounted on an axle rotated by the drive device, the rollers being disposed a distance from one another at right angles relative to the forward feed direction of the paper. The drive rollers are mounted on the axle so as to run freely on the axle in the direction of rotation of the axle, but lock when attempted to be rotated in the opposite direction so that skewed paper is easily and automatically aligned to move in a straight path. Each drive roller has an idler roller associated therewith.
