Claims

[Claims for Utility Model Registration] It has a side guide that is attached parallel to the paper feeding direction and movable with respect to the cassette body, and an end guide that is attached perpendicular to the paper feeding direction and movable with respect to the cassette body. In a paper feed cassette that selectively accommodates paper of multiple sizes and is removably attached to an image forming apparatus, the paper size is selectively turned on and off by movement of the side guide and end guide, and the paper size is automatically detected. A paper feed cassette comprising: a plurality of first switch means for detecting whether the side guide or the end guide is in contact with the paper; and a second switch means for detecting whether or not the side guide or the end guide is in contact with the paper.
