  • Playing card shuffling machine
    Patent number: 6299167
    Abstract: A playing card shuffler for shuffling a stack of playing cards with random distribution.

  • Playing card shuffler apparatus and method
    Patent number: 6019368
    Abstract: A playing card shuffler having an unshuffled stack holder which holds an infeed array of playing cards. One or more ejectors are mounted adjacent the unshuffled stack holder to eject cards from the infeed array at various random positions. Multiple ejectors are preferably mounted on a movable carriage. Extractors are advantageously used to assist in removing playing cards from the infeed array. Removal resistors are used to provide counteracting forces resisting displacement of cards, to thereby provide more selective ejection of cards from the infeed array.

  • Playing card shuffling machines and methods
    Patent number: 5584483
    Abstract: Playing card shufflers having unshuffled stack holders which hold infeed arrays of playing cards. Ejectors are mounted adjacent an unshuffled stack holder, which can be stationary or movable. Cards are ejected and discharged from the infeed array at various random positions. The ejectors can be mounted on a movable carriage. Extractors are advantageously used to assist in removing playing cards from the infeed array. Removal resistors are used to provide counteracting forces resisting displacement of cards, to thereby provide more selective ejection of cards from the infeed array. One embodiment mounts over the edge of a card table.
