A single tray finishing apparatus that can receive, fasten, and sort sets of copy sheets for use in paper feeder system of an electrographic copier, printer, or other related devices is disclosed. As shown in figure 1, a paper path 1 is used to transport copy sheets 2 to both a stacking tray 3 and a compiling member 4. A portion of the compiling member 4 extends over the stacking tray 3. In a preferred embodiment, a scuffing wheel 5 registers the copy sheets for fastening (if desired) by a stapler 6. A retraction mechanism 7 retracts the compiling member 4 and the set of copy sheets drop onto the stacking tray 3 as it is being ejected by fingers 9 . As sets of copy sheets are placed on or removed from the stacking tray 3, a constant stacking height is maintained by use of a sensing arm 8. In an alternative embodiment, figure 2, sorting stapled sets of copy sheets can be accomplished by lowering the stacking tray 3 to an appropriate mail slot 10 and releasing a gate 11 on the stacking tray.
