Abstract

A paper feeding apparatus and a printer wherein an idle roller is brought into contact with a separation pad by a roller spring for generating urging force smaller than that of a separation pad for separating a paper sheet to be fed by a paper feeding roller having a D-shape side cross section from a next paper sheet; a restraining pin for restraining movement of the separation pad toward the paper feeding roller when the paper sheet is not held between the separation pad and the paper feeding roller is provided; a pair of conveying rollers are temporarily and inversely rotated after the leading end of the paper sheet has passed through a nipping portion between the pair of the conveying rollers and in a state where the paper sheet is not held between the separation pad and a circular-arc portion of the paper feeding roller so as to arrange the leading end of the paper sheet along the nipping portion so that diagonal conveyance of the paper sheet is smoothly prevented and the load acting on the fed paper sheet is reduced.
