Claims

[Scope of Claim for Utility Model Registration] A cassette holder for placing a paper feed cassette with a stack of paper on a bottom plate whose rear end is pivotally attached to the bottom of the cassette is provided at one end of the cassette insertion opening of the main body of the machine. The cassette is rotated in a substantially horizontal plane around a vertical axis, and the cassette is inserted into the cassette insertion slot. Push up to the operating position corresponding to the lower end of the calling roller at the position,
In a paper feeding device such as a copying machine that feeds paper by engaging the top surface of a stack of paper stacks placed on a bottom plate with the above-mentioned feed roller, the cassette is pivotably supported around a horizontal shaft provided at the front end of the cassette. A bottom plate push-up lever that can push up the cassette bottom plate, and a cassette that is fixed to the machine body side and is placed on the cassette holder and rotated to a predetermined mounting position, penetrate the front end wall of the cassette and protrude into the cassette. A paper feeder comprising a bottom plate push-up auxiliary member that engages with the bottom plate push-up lever to push the bottom plate up to the operating position.
