Abstract

A copying machine includes a pair of copy material holders which are movable relative to a feed roller for selectively feeding copy material from either of the holders. In one embodiment, one of the holders is movable from a position adjacent the feed roller to a second position in which it receives already copied sheets. In a further embodiment, one of the holders is a pivoted cassette which is normally biased to a position adjacent the feed roller. This first cassette is movable away from the feed roller in response to the positioning of the second holder, also formed as a cassette, adjacent the feed roller. The second holder is slid into position on stationary rails.
