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 (13)

1. A method of performing a security check on a card handling system used at a gaming table comprising:
providing a card receiver for receiving cards to be processed;
providing a single stack of card-receiving compartments generally adjacent to the card receiver and means for moving the stack;
providing a card-moving mechanism between the card receiver and the stack and moving cards from the card receiver to the card-receiving compartments;
providing a second card receiver for receiving processed cards;
providing a second card moving mechanism for moving cards from the compartments to the second card receiver; and counting cards within specified areas within the card handler during a period wherein cards are moved within the card handling system;
wherein card movement from the card receiving compartments to the second card receiver is halted, all cards in the area of the gaming table and the second card receiver are retrieved inserted into the card receiver for receiving cards to be processed, the cards inserted into the card receiver for receiving cards to be processed are counted as they move to the stack of card-receiving compartments, and adding the number of retrieved cards counted to the number of cards counted as within specified areas within the card handler to provide a final count of cards.
2. The method of claim 1 wherein a total number of cards to be used in the play of a game on the casino gaming table is identified to a microprocessor prior to starting play of the game.
3. The method of claim 2 wherein the final count of cards is compared to the total number of cards identified to the microprocessor prior to starting play of the game.
4. The method of claim 3 wherein only cards within the stack of card-receiving compartments are counted.
5. The method of claim 3 wherein cards are counted within the stack of card-receiving compartments and the second card receiving area.
6. A card shuffling apparatus capable of delivering a continuous supply of shuffled cards on demand, the apparatus comprising:
a card shuffling chamber for randomizing cards;
a card receiver and feed mechanism for receiving and feeding unshuffled cards into the shuffling chamber;
at least one sensor for sensing the presence of a card as the card is being fed into the shuffling chamber;
at least one sensor for sensing the presence of a card as the card is being removed from the shuffling chamber;
a mechanism for removing cards from the shuffling chamber on demand to provide a continuous supply of shuffled cards;
a visual display; and a microprocessor, wherein the microprocessor is programmed to:
receive signals from sensors and count cards entering and being removed from the shuffling chamber and to maintain a count of cards present in the shuffling chamber;
receive instructions from an apparatus user to initiate a card counting process, wherein the card counting process includes discontinuing of operation of the card removal process, pausing until cards outside of the shuffling chamber are loaded into the feed mechanism, receiving an indication from the at least one sensor for sensing the presence of a card as the card is being fed into the shuffling chamber and the at least one sensor for sensing the presence of a card as the card is being removed from the shuffling chamber of an indication of current card count status on the visual display.
7. The apparatus of claim 6 wherein the indication from the at least one sensor for sensing the presence of a card as the card is being fed into the shuffling chamber and the at least one sensor for sensing the presence of a card as the card is being removed from the shuffling chamber indicates the number of cards added and removed from the shuffling chamber.
8. The apparatus of claim 6 wherein the shuffling chamber comprises a plurality of mixing compartments, wherein the mixing compartments move relative to the card feeding mechanism.
9. The apparatus of claim 6 wherein the mechanism for providing access to a continuous supply of cards comprises a shoe.
10. The apparatus of claim 6 wherein the indication of card count status comprises a card count.
11. The apparatus of claim 6 wherein the indication of card count status comprises an error signal.
12. A method of performing a security check on an automatic card handling system comprising:
Providing a card shuffling chamber;
Providing a feed mechanism for delivering cards to the card shuffling chamber;
Providing an unloading mechanism for removing cards from the shuffling chamber;
Maintaining a current count of cards in the card shuffling chamber;
Halting the card shuffling process;
Loading all cards outside of the shuffling chamber into the shuffling chamber;
Counting cards loaded into the shuffling chamber after halting the shuffling process;
and Displaying a sum of the number of cards present in the shuffling chamber prior to halting and the cards loaded into the shuffling chamber after halting.
13. An apparatus for continuously shuffling playing cards, said apparatus comprising:
a card receiver for receiving a first group of cards;

a single stack of card-receiving compartments generally adjacent to the card receiver, said stack generally vertically movable, and means for moving the stack;
a card-moving mechanism between the card receiver and the stack;
a processing unit that controls the card-moving mechanism and the means for moving the stack so that cards placed in the card receiver are moved into a selected number of compartments; and a second card receiver for receiving cards from the compartments the card receiver for receiving the first group of cards supporting the cards so that gravity applies a force against the cards and maintains an inter-operative position between the cards and the card moving mechanism.
