US Patent 8651380 System for processing folded documents

A system for processing folded documents is disclosed. The system includes an input hopper configured to receive a stack of folded documents and an imaging area in which each of the documents is imaged. A pick-up mechanism is configured to transport each of the folded documents from the input hopper to the imaging area. The pick-up mechanism includes first and second barriers that are spaced apart to define a gap through which each of the folded documents is passed, wherein the gap is dimensioned to prevent passage of more than one of the folded documents. Preferably, the system also includes a detection system that is operable to detect the passage of more than one of the folded documents through a detection zone.
