Abstract
An auto document feeder includes a housing unit, spatially interconnected first and second paths, an inverting path in spatial communication with the first path, a bypass path spatially inter communicating the second path and the inverting path, a feeding roller unit for feeding documents onto the first path, first and second transfer roller units disposed respectively on the first and second paths, an ejecting roller unit aligned with the second path and the inverting path, and two switching gates disposed pivotally on the housing unit for guiding movement of the documents. The bypass path and the switching gates are internal to the ejecting roller unit so as to reduce document transportation travel.
