ABSTRACT:
A paper feed cassette capable of inhibiting a paper from being warped in a direction substantially perpendicular to a paper feed direction while minimizing increase in the number of component and inhibiting the paper from being plastically deformed into a curved shape is obtained. The paper feed cassette includes a cassette body storing the paper, a first lift member for lifting up the paper so as to bring the paper into contact with a paper feed roller in printing, and a second lift member for lifting up the paper so as to produce bending caused by droop of the rear in the paper feed direction of the paper due to the paper's own weight in printing.
