したことを特徴とする給紙機構。 A mounting port is provided for mounting a paper feed cassette in which paper is stored, and an upward biasing force is applied to the interior of the mounting port when the paper feed cassette is mounted, causing the movable bottom plate of the paper feed cassette to swing upward. In a sheet feeding mechanism, a pressing lever is arranged so as to be rotatable in the vertical direction and press the uppermost sheet of paper against the sheet feeding roller. A paper feeding mechanism characterized by having a release lever that can be rotated.
