送防止装置。[Scope of Claim for Utility Model Registration] A brake member and the leading edge of the paper in the paper cassette are pressed against the paper feed roller, and the paper is fed out from within the paper cassette by the rotation of the paper feed roller, and the paper is transferred to the paper feed roller. In the double feeding prevention device, the paper feed roller is divided into a plurality of regions in the axial direction, and the friction coefficients of adjacent regions are set to different values. and the friction coefficient of the brake member is set to be small in a portion corresponding to a paper feed roller region with a large friction coefficient, and large in a portion corresponding to a paper feed roller region with a small friction coefficient. Double feed prevention device.
