Abstract
An automatic document feeder mounted removably to a computer input device having a medium receiving and supporting surface includes a plurality of interconnectable modular assemblies for defining a medium path that extends from a medium input tray to a medium output tray via the medium receiving and supporting surface of the computer input device. One of the modular assemblies is a main chassis assembly includes an integrally formed main chassis shell having a substantially planar base. The input tray extends upwardly from the base and has a document receiving surface with a concave shape in both the vertical and horizontal planes to help facilitate proper sheet stiffening and alignment for sheet loading purposes onto the receiving and supporting surface of the computer input device. A paper pick and transport mechanism is housed in the main chassis and protrudes through a set of apertures in the output tray. The mechanism includes a pair of spaced apart stop fence devices for supporting a stack of input print media and a centrally disposed pick roller disposed between the stop fence devices for picking individual sheets from the input tray.
