Sheet feeding device

A sheet feeding cassette in which a plurality of sheets can be contained and from which the sheets can be fed one by one by at least two feed rollers when the sheet feeding cassette is mounted on an apparatus, comprising:

• a sheet containing section for containing the sheets;
• a mounting means for mounting the sheets arranged in said sheet containing section, wherein at least a forward portion of said mounting means in the direction in which sheets are fed is movable up and down, and wherein a facing position of the forward portion of said mounting means comes into direct contact with the each feed rollers when no sheets are contained in said containing section;
• an urging means for urging said mounting means upward at least when the sheets are fed, such that the sheets are brought into contact with the each feed rollers;
• and
• a non-slip means arranged on an upper surface of the forward portion of said mounting means, wherein said non-slip means is in contact with a last sheet mounted on said mounting means, and said non-slip means including a base portion which locates forward or backward of the two feed rollers in the sheets feeding direction and a facing portion facing to the roller axis aside the two rollers and being arranged in such a position that it does not come into direct contact with said two feed rollers even when no sheets are contained in said sheet containing section.
