Abstract

This invention relates to the classification of a stream of documents, such as mixed mail pieces, into size and orientation of categories for subsequent processing. The apparatus includes a laser beam which scans a conveying belt upon which the documents are placed. Appropriate circuitry is provided so that a determination may be made as to the length and width of the document being conveyed across the belt. Downstream from the belt is a segregation system in which the various sizes of documents are segregated according to size in response to the determination of the circuitry.
