Abstract
Apparatus for loading automatically fed documents and manually fed documents into a document transport. The loader apparatus includes a plurality of document driver devices situated along a track and capable of automatically accommodating documents of various thicknesses and sizes, the driver devices being actuable for downwardly driving received documents for registering their bottom edges along a horizontally extending registration surface, as well as for controllably gating the documents, and for forwardly driving the upstanding documents along the track and into a document processing transport. A preloader transport is provided for applying documents to the loader issuing from automatic feeder apparatus. The loader's track configuration includes an undercut registration surface for supporting the document's bottom edge in such manner as to decrease the likelihood of document distortion during the loading process. An improved light absorption device is provided in combination with a reflective light sensor for sensing position of the documents within the track.
