Abstract
A sheet material feeding device includes: a press plate which is provided at a bottom portion of a cassette and on which sheet materials are loaded and which is swingable upward and downward; a feed roll which is positioned above the press plate and which feeds an uppermost sheet material of the sheet materials by rotating while contacting the uppermost sheet material; a limiting member provided above the press plate and limiting a stacked height of the sheet materials; a spring urging the press plate upward so that the uppermost sheet material abuts the limiting member; and a presser mechanism which swings the press plate downward against urging force of the spring when the uppermost sheet material is fed to a predetermined position by the feed roll. Accordingly, when the uppermost sheet material is fed to the predetermined position by the feed roll, the press plate is swung downward, and there is no frictional resistance between the limiting member and the uppermost sheet material.
