Abstract
A paper feed cassette having a size detection function has a paper stage formed integrally with a rear end restricting plate for restricting the rear end of paper sheets. On the bottom of the paper stage, a plurality of rib-like detection targets are arranged in the paper feed direction. The detection targets are detected by a plurality of detection switches arranged in the paper feed direction in a paper feed portion inside the main body of an image forming apparatus. A discriminator receives the detection signals from the detection switches and thereby recognizes the paper size and the presence/absence of the paper feed cassette.
