ABSTRACT:
The present invention relates to a paper feeding module of a color picture printer for driving a picture back and forth through a printing module of the printer for printing. The printer comprises a housing. The printing module is installed inside the housing for printing the paper. The paper feeding module comprises a first roller, a second roller and an elastic device. The first roller is horizontally installed inside the housing and is rotatable. The second roller comprises at least two cylindrical sleeves mounted onto a revolving axle for clamping the paper with the first roller. The second roller is installed in parallel with, in contact with and above the first roller inside the housing, is moveable in a vertical direction, and is rotatable. When the first and second rollers are rotated in opposite directions, the paper is clamped and driven between the first roller and the sleeves of the second roller. The elastic device is installed between the second roller and the housing and comprises a plurality of elastic arms in contact with two ends of the revolving axle of the second roller and the portions of the revolving axle between each adjacent pair of sleeves. The pads uniformly depress the revolving axle of the second roller so that each sleeve of the second roller is maintained in close and even contact with the first roller so as to clamp the paper.
