Apparatus for feeding recording medium, having means for easy handling of jamming trouble.

摘要

A feeding apparatus for a printer wherein an uppermost sheet of a sheet stack placed on a support member (66) is delivered by a feed roll (118) in contact with the uppermost sheet, through a clearance formed between a presser member which engages the upper surface of the uppermost sheet, and an elastic member which is disposed adjacent to the presser member for abutting contact with the edges of the sheet stack. The apparatus includes a support mechanism for supporting the presser and elastic members such that the two members are movable toward and away from each other, and a biasing spring for biasing the two members toward each other. The relative position of the presser and elastic members and the amount of the clearance therebetween during a normal sheet feeding operation are determined by a stopper device. In the event of jamming of a sheet between the presser and elastic members, the two members may be moved away from each other against a biasing action of the spring, whereby the jammed sheet may be easily removed. Also disclosed are various other devices for facilitating the removal of the jammed sheet, such as a device for positively enlarging the clearance between the presser and elastic member, and a device for moving sheet advancing rolls away from each other.
