ABSTRACT:
A feed cassette apparatus for retaining a loaded feed cassette in a cassette housing space containing a feed roller, wherein the feed cassette is loaded or unloaded in the direction parallel to the axis of the feed roller. The apparatus includes a cassette case and a plurality of positioning devices. The cassette case is movable in the feed-cassette loading direction and is capable of housing feed cassettes of different sizes. The positioning devices are disposed at different positions in the cassette case to suit the different-sized feed cassettes, and position the end of a stack of sheets in a given feed cassette under the feed roller. A feed cassette to be housed in the cassette case is positioned by the positioning device corresponding to the feed cassette size. As a result, when the cassette case is moved in the loading direction in order to load the feed cassette into the cassette housing space, the end of the stack of sheets in the feed cassette is brought precisely into position under the feed roller.
