Filed: 1983-11-24
Abstract: PURPOSE:To prevent a paper from skewing by an extremely simple construction, by a method wherein feeding rollers on the more downstream side in the paper- feeding direction have smaller pinch widths, in a paper feeder for a printer. CONSTITUTION:The pinch width W1 generated by the contact of a pinch roller 5 with a reference feeding roller 6 is the greatest, since the roller 6 is located at the most upstream position.
