Abstract

The present invention provides an apparatus and method for moving playing cards from a first group of cards into a second group of cards, wherein the second group of cards is randomly arranged or shuffled. The apparatus comprises a card receiver for receiving the first group of cards, a single stack of card-receiving compartments generally adjacent to the card receiver, the stack generally vertically movable, an elevator for moving the stack, a card-moving mechanism between the card receiver and the stack for moving cards one at a time into a selected one of the compartments, another card moving mechanism for moving cards from one of the compartments to a second card receiver and a microprocessor that controls the card-moving mechanisms and the elevator. A count of cards within specified areas of the card handling system is maintained and card handling is halted and all cards counted by adding a count of all cards not within the specified areas to the total of cards counted within the specified areas.

Claims

1. A method of operation of a card shuffling apparatus, comprising:

providing a card receiver having a support surface for supporting a single stack of cards to be randomized;

providing a card shuffling chamber comprising at least two adjacent card receiving compartments, each compartment capable of receiving multiple cards, each of the multiple cards in contact with an adjacent one of the multiple cards;

moving cards individually from the card receiver and randomly to a compartment in the card shuffling chamber with a first card moving mechanism during shuffling;

moving cards with a second card moving mechanism from a card receiving compartment only to a shuffled card receiver having a support surface for receiving randomly arranged cards and for distribution of cards to players by the dealer; and

controlling operation of the continuous card shuffling apparatus with a microprocessor.

2. The method of claim 1 wherein cards from more than one compartment are moved to the shuffled card receiver to form a set of shuffled cards.

3. The method of claim 2 wherein the set of shuffled cards is a hand of cards.

4. The method of claim 3 wherein a buffer of a selected number of cards is maintained between the card receiving compartment and the shuffled card receiver.

5. The method of claim 2 wherein cards are first unloaded from a first compartment into the shuffled card receiver and then cards from a second compartment are delivered to the shuffled card receiver.

6. The method of claim 5 wherein cards in the shuffled card receiver form a hand of cards for distribution of the hand of cards to players by the dealer.

7. The method of claim 6 wherein a buffer of a selected number of cards is maintained between the card receiving compartment and the shuffled card receiver.

8. The method of claim 7 wherein cards are randomly inserted into said first compartment and said second compartment from the first group of cards.

9. The method of claim 8 wherein cards in the shuffled card receiver form a hand of cards.

10. The method of claim 7 wherein cards in the first compartment and cards in the second compartment are randomly selected for movement to the shuffled card receiver.

11. The method of claim 10 wherein cards in the shuffled card receiver form a hand of cards.

12. The method of claim 5 wherein a buffer of a selected number of cards is maintained between the card receiving compartment and the shuffled card receiver.

13. The method of claim 2 wherein a buffer of a selected number of cards is maintained between the card receiving compartment and the shuffled card receiver.

14. The method of claim 1 wherein a buffer of a selected number of cards is maintained between the card receiving compartment and the shuffled card receiver.

15. A method of card shuffling comprising:

supporting a first group of cards to be randomized from a single support surface;

moving cards individually from the first group of cards on the single support surface and randomly to at least a first compartment and a second compartment during shuffling, at least one of the first compartment and the second compartment containing multiple cards, each of the multiple cards in contact with an adjacent one of the multiple cards;

moving cards from the first compartment to a shuffled card receiver having a support surface for receiving randomly arranged cards and then moving cards randomly from the second compartment only to a shuffled card receiver for distribution of the cards to players by the dealer; and

all moving controlled with a microprocessor.

16. The method of claim 15 wherein cards in the first compartment and cards in the second compartment are randomly selected for movement to the shuffled card receiver.

17. The method of claim 16 wherein cards in the shuffled card receiver form a hand of cards.

18. The method of claim 15 wherein cards in the shuffled card receiver form a hand of cards.

19. The method of claim 15 wherein the at least a first compartment and a second compartment are selected from the group consisting of vertical slots, vertical compartments, carousel slots, and carousel compartments.

20. A method of card shuffling comprising:

supporting a first single group of cards to be randomized on a single support surface;

moving cards individually from the first group of cards on a support surface randomly to at least a first compartment and a second compartment, at least one of the first and second compartment containing multiple cards, each multiple card being in contact with an adjacent one of the multiple cards;

moving cards from the first compartment to a shuffled card receiver having a support surface for receiving randomly arranged cards and then moving cards from the second compartment only to a shuffled card receiver for distribution of the cards to players by the dealer; and

all moving controlled with a microprocessor.

21. A method of operation of a card shuffling apparatus, comprising:

providing a card receiver having a support surface for supporting a single stack of cards to be randomized;

providing a card shuffling chamber comprising at least two adjacent card receiving compartments, each compartment capable of receiving multiple cards, each of the multiple cards in contact with an adjacent one of the multiple cards;

moving cards individually from the card receiver and randomly to a compartment in the card shuffling chamber with a first card moving mechanism during shuffling;

moving cards with a second card moving mechanism from a card receiving compartment to a shuffled card receiver having a support surface for receiving randomly arranged cards and for distribution of cards to players by the dealer; and

controlling operation of the continuous card shuffling apparatus with a microprocessor.

22. A method of card shuffling comprising:

supporting a first group of cards to be randomized from a single support surface;

moving cards individually from the first group of cards on the single support surface and randomly to at least a first compartment and a second compartment during shuffling, at least one of the first compartment and the second compartment containing multiple cards, each of the multiple cards in contact with an adjacent one of the multiple cards;

moving cards from the first compartment to a shuffled card receiver having a support surface for receiving randomly arranged cards and then moving cards randomly from the second compartment to a shuffled card receiver for distribution of the cards to players by the dealer; and

all moving controlled with a microprocessor.

23. A method of card shuffling comprising:

supporting a first single group of cards to be randomized on a single support surface;

moving cards individually from the first group of cards on a support surface randomly to at least a first compartment and a second compartment, the first and second compartment containing multiple cards, each of the multiple cards in contact with an adjacent one of the multiple cards;

moving cards from the first compartment to a shuffled card receiver having a support surface for receiving randomly arranged cards and then moving cards from the second compartment to a shuffled card receiver for distribution of the cards to players by the dealer; and

all moving controlled with a microprocessor.
