The bottom surface of a paper cassette that supports recording paper is configured of a first bottom surface and a second bottom surface. The second bottom surface is formed of a swing member having a fulcrum at the downstream side in the paper feeding direction and being capable of swinging about the fulcrum with the upstream side in the paper feeding direction serving as a free end, thereby providing a structure in which an angle formed by the second bottom surface and a separation slope increases when the second bottom surface is caused to sink downward by a swing of the swing member.
