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. An apparatus for shuffling playing cards, said apparatus comprising:

a first card receiver for receiving a first group of cards,

card receiving compartments generally adjacent to the card receiver, the card receiving compartments being moveable with respect to the first card receiver, and wherein each card receiving compartment may have more than one card inserted therein,

at least one first card mover acting between the first card receiver and the card receiving compartments,

a processing unit that controls the card mover,

a second card receiver for receiving cards from the card receiving compartments,

at least one second card mover acting between the card receiving compartments and the second card receiver,

the processor directing both random placement of cards from the first card receiver into the card receiving compartments and random placement of cards in the card receiving compartments into the second card receiver.

2. The apparatus of claim 1 wherein the shuffling apparatus is a continuous shuffling apparatus.

3. An apparatus for shuffling playing cards, said apparatus comprising:

a first card receiver for receiver a first group of cards

card receiving compartments generally adjacent to the card receiver and the card receiving compartments being moveable with respect to the first card receiver

at least one first card mover acting between the first card receiver and the card receiving compartments

a processing unit that controls the card mover,

a second card receiver for receiving cards from the card receiving compartments

at least one second card mover acting between the card receiving compartments and the second card receiver,

the processor directing both random placement of cards from the first card receiver into the card receiving compartments and random placement of cards in the card receiving compartments into the second card receiver wherein the processor is programmed to direct placement of more than one card into at least one card receiving compartment.

4. The apparatus of claim 3 wherein at least some card receiving compartments into which more than one card is provided constitutes a hand.

5. An apparatus for continuously shuffling playing cards with two distinct randomization steps, the apparatus comprising:

an initial card receiver;

a final card receiver;

a series of card receiving compartments that are moveable in tandem, and wherein each card receiving commandment may have more than one card inserted therein

a card mover acting between the card receiving compartments and the final card receiver,

at least one first card mover acting between the initial card receiver and the card receiving compartments,

a processing unit that controls the card movers,

the processing unit directing both random placement of cards into the card receiving compartments and random placement of cards in the card receiving compartments into the final card receiver.

6. The apparatus of claim 5 wherein the card receiving compartments are within a carousel.

7. The apparatus of claim 5, wherein the series of card receiving compartments are arranged in a stack.

8. The apparatus of claim 7, wherein the stack is verticaiiy disposed.

9. The apparatus of claim 5, wherein groups of cards are formed in the card receiving compartments.

10. The apparatus of claim 9, wherein a group of cards defines a hand.

11. The apparatus of claim 10, wherein at least one group of cards defines a portion of a hand.

12. The apparatus of claim 9, wherein cards are moved as a group into the final card receiver.

13. The apparatus of claim 5, wherein the final card receiver dispenses cards individually.

14. An apparatus for continuously shuffling playing cards with two distinct randomization steps, the apparatus comprising:

an initial card receiver;

a final card receiver;

a series of card receiving compartments selected from vertical slots, vertical compartments, elevator slots, carousel slots, carousel compartments that are moveable in tandem,

a card mover acting between the card receiving compartments and the final card receiver,

at least one first card mover acting between the initial card receiver and the card receiving compartments,

a processing unit that controls the card movers,

the processing unit directing both random placement of cards into the card receiving compartments and random placement of cards in the card receiving compartments into the final card receiver, wherein there are at least 4 card receiving compartments and a maximum of 19 card receiving compartments.

15. An apparatus for shuffling playing cards, said apparatus comprising:

a first card receiver for receiving a first group of cards,

card receiving compartments generally adjacent to the card receiver, the card receiving compartments selected from vertical slots, vertical compartments, elevator slots, carousel slots, carousel compartments being moveable with respect to the first card receiver, and wherein each card receiving compartment may have more than one card inserted therein.

at least one first card mover acting between the first card receiver and the card receiving compartments,

a processing unit that controls the card mover,

a second card receiver for receiving cards from the card receiving compartments,

at least one second card mover acting between the card receiving compartments and the second card receiver,

the processor directing both random placement of cards from the first card receiver into the card receiving compartments and random placement of cards in the card receiving compartments into the second card receiver.

16. The apparatus of claim 15 wherein the shuffling apparatus is a continuous shuffling apparatus.

17. The apparatus of claim 15 wherein the processor is programmed to direct placement of more than one card into at least one card receiving compartment.

18. The apparatus of claim 17 wherein at least some card receiving compartments into which more than one card is provided constitutes a hand.
