Abstract
A multiple document feed detection system, such as for use in an automatic document processing system, is disclosed. The multiple document feed detection system includes a plurality of light sources oriented to direct light across a path of travel of documents. The system also includes a plurality of photodetectors placed adjacent to the path of travel, with each photodetector placed on an opposite side of the path of travel from a corresponding light source and oriented toward the corresponding light source. The plurality of photodetectors is configured to detect transmissivity of light emitted from the light sources through documents passing through the path of travel. The system further includes a signal detection and voting module interconnected with the light sources and the phototransistors, the signal detection and voting module configured to detect the presence of the overlapping documents passing through the path of travel.
