  • Patent number: 4995747
    Abstract: A paper stacking apparatus is for an office machine, wherein the office machine has a forward end and a rear end and includes rollers for sequentially supplying sheets of paper upwardly along a generally vertical path. The sheets extend transversely of the office machine. The path is located between the front end and the rear end. The paper stacking apparatus includes a support frame located above the rollers for sequentially supplying said sheets. A paper guide element is mounted within the support frame in alignment with the path. A forward stacker is mounted on the support frame forwardly of the paper guide element. A rear stacker is mounted on the support frame rearwardly of the paper guide element. The paper guide element is selectively movable to a forward position and to a rear position. The paper guide element at the forward position directs the sheets to the forward stacker for forward to rear stacking of the sheets thereon.
