  • Patent number: 6267248
    Abstract: A collation and/or sorting apparatus for groups of articles is exemplified by a sorting and/or shuffling device for playing cards. The apparatus comprises a sensor (15) to identify articles for collation and/or sorting, feeding means to feed cards from a stack (11) past the sensor (15) to a delivery means (14) adapted to deliver cards individually to a preselected one of a storing means (24) in an indexable magazine (20). A microprocessor (16) coupled to the feed means (14), delivery means (18), sensor (15) and magazine (20) determines according to a preprogrammed routine whether cards identified by sensor (15) are collated in the magazine (20) as an ordered deck of cards or a randomly ordered or “shuffled” deck.
