Claims

[Scope of Claim for Utility Model Registration] A paper feed cassette that stores sheets of paper in a stacked manner and is removably attached to the main body of the apparatus, a suction cup that is provided on the uppermost surface of the paper in the cassette so as to be able to be closely spaced from each other, and a device that moves the suction cup up and down. In a paper feeding device comprising a means for moving the paper and a pressure reducing means for reducing the pressure between the suction cup and the paper to a negative pressure, a stepped portion is formed on the side wall of the paper feeding cassette, and a stepped portion is formed on the side wall of the paper feeding cassette. is provided with a member for a cassette lock that fits into the stepped portion of the paper feed cassette in conjunction with the operation of the elevating mechanism when the suction cup is lowered; The member is supported so as to be slidable in the cassette insertion/removal direction, and when the cassette is moved in the pull-out direction while being fitted into the step, the member is supported by the step and the step on the apparatus main body side. A paper feeding device characterized in that a member for locking the cassette is inserted into the device to lock the cassette from being pulled out.
