Abstract

A frame selectively supports sheet cassettes of various widths, one edge of the selected cassette being aligned against a first side wall of the frame. A first feed roller is operatively disposed above the selected cassette and spaced by a predetermined distance from the first side wall. For a maximum size cassette, the opposite edge of the cassette is aligned with a second side wall of the frame. A second feed roller is axially movable and embraced by a roller carrier which is biased into engagement with the second side wall so that the second feed roller is spaced from the second side wall by the same predetermined distance to ensure symmetrical sheet feed. A stop member integral with the roller carrier abuttingly prevents narrower cassettes from being inserted into the frame. To utilize a narrower cassette, an insert is mounted on the frame so that the edges of the cassette engage with the first side wall of the frame and with the insert respectively. The stop member prevents insertion of even narrower cassettes and the insert prevents insertion of wider cassettes.
