Abstract: A paper cassette which stores a number of types of media on a media load plate which is rotatable and the other end of the media load plate is rotated up and down by a reset arm and performs paper feed with the media pushed against a hopping roller by a spring which pushes the media load plate upwards. The paper cassette further includes an auxiliary resilient member which pushes the reset arm up, a sub-arm having one end which abuts against the auxiliary resilient member and rotates together with the auxiliary resilient member and a regulator provided in the range of rotation of the sub-arm for regulating the rotation of the sub-arm in accordance with the size of the media.

Abstract: An automatic paper feed device is formed to store multiple types of different sized media in a single paper cassette and performs paper-feeding. A media load plate is loaded with said multiple types of different sized media. A media back edge guide assembly is mounted to a media load plate on which is loaded multiple types of different-sized media, to position the media loaded on the media load plate.
