ABSTRACT:
In a sheet feeding device for a printing apparatus for feeding one sheet after another to a printing station, a stopper hook is located slightly posterior to point of contact between a platen and a roller or between two rollers brought into and out of pressing contact with each other, and a sheet fed to the printing station is stopped by the stopper hook and has its position corrected, if it has a skew, while the platen and the roller or the two rollers are out of contact with each other. Thus a sheet free from skew is pressed by the roller against the platen or the roller to enable automatic skewless sheet feeding to be effected.
