Abstract: The present invention provides an improvement for a document feeder comprising a feed deck, a separator assembly for separating and feeding individual documents, the separator assembly including a separator wheel disposed above the feed deck, drive structure for driving the separator wheel, and structure for adjustably positioning the separator wheel assembly to a position relative to the feed deck commensurate with the material being fed. The improvement comprises structure for pivotally coupling the document feeder to vertical frame members. The coupling structure is located at one end of the document feeder near the separator assembly. There are a pair of leg members extending below the feed deck, each of the leg members resting on a horizontal frame member at opposite sides of the document feed path. The leg members are laterally spaced so as not to interfere with documents being conveyed by the underlying document transport.
