Abstract
A sheet feeding device includes a sheet feed cassette, a bottom plate and an end wall mechanism. When the number of recording media sheets decreases, the bottom plate hinged at a trailing edge thereof rises about the hinged end to keep the top sheet of the recording media sheets in contact with a sheet feed roller. The end wall mechanism includes a first urging member, a first pressing member, a support member, and a second pressing member, and aligns and presses the trailing edge of the recording medium. The first pressing member urged by the first urging member and supported by the support member presses the trailing edge of the recording medium. The second pressing member urged by the second urging member moves down due to the weight of the recording medium on the second pressing member and moves up when the number of the recording media sheets decreases.
