ABSTRACT:
A copier particularly suitable for duplex copying is disclosed which includes a paper tray unit comprising first and second paper trays having a common sheet feeder. The first tray is mounted for movement between a lowered, operative position in which it is seated within the second tray and operatively associated with the sheet feeder and a raised inoperative position in which it is spaced over the second tray and the latter is operatively associated with the sheet feeder. The unit is mounted on slides for withdrawal to facilitate access and the arrangement is such that both trays are withdrawable together when the first tray is lowered and the second tray is withdrawable alone when the first tray is raised.
