Abstract

The present invention provides a machine for shuffling multiple decks of playing cards including a first vertically extending magazine for holding a stack of unshuffled playing cards, and second and third vertically extending magazines each for holding a stack of cards, the second and third magazines being horizontally spaced from and adjacent to the first magazine. A first card mover is at the top of the first magazine for moving cards from the top of the stack of cards in the first magazine to the second and third magazines to cut the stack of unshuffled playing cards into two unshuffled stacks. Second and third card movers are at the top of the second and third magazines, respectively, for randomly moving cards from the top of the stack of cards in the second and third magazines, respectively, back to the first magazine, thereby interleaving the cards to form a vertically registered stack of shuffled cards in the first magazine.

Claims

1. An automatic card shuffler comprising:

a card shuffling mechanism for randomizing an order of cards; and

a computerized control system for controlling the operation of the card shuffler, wherein all inputs and outputs of the control system are operatively coupled to at least the card shuffler by means of a data bus, wherein the data bus is optically isolated and the card shuffling mechanism comprises three substantially vertically disposed compartments, each compartment having a moveable lower surface and an elevator capable of moving the lower surface vertically.

2. The automatic card shuffler of claim 1, wherein all inputs and outputs to and from the control system are operatively coupled to the data bus.

3. An automatic card shuffler comprising:

a card shuffling mechanism for randomizing an order of cards; and

a computerized control system for controlling the operation of the card shuffler, wherein all inputs and outputs of the control system are operatively coupled to at least the card shuffler by means-of a data bus, wherein the data bus is optically isolated to act as a barrier to electrostatic discharge and the card shuffling mechanism further includes a plurality of card moving mechanisms located proximate an upper surface of each compartment, wherein the card shuffling mechanisms are capable of transferring cards individually from a compartment to an adjacent compartment.

4. An automatic card shuffler comprising:

a card shuffling mechanism for randomizing an order of cards; and

a computerized control system within the automatic card shuffler for controlling the operation of the card shuffler,

wherein at least some inputs and outputs of the control system are optically isolated and operatively coupled within the card shuffler to at least the computerized controller of the card shuffler by means of a data bus to act as a barrier to electrostatic discharge.
