Abstract

The present invention provides an apparatus and method for moving playing cards from a first group of cards into plural hands of cards, wherein each of the hands contains a random arrangement of cards. 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, and a microprocessor that controls the card-moving mechanism and the elevator so that an individual card is moved into an identified compartment. The number of compartments receiving cards and the number of cards moved to each compartment may be selected. An apparatus for feeding cards, comprising a surface for supporting a stack of cards, a feed roller with a frictional outer surface, a drive mechanism for causing rotation of the feed roller, a pair of speed-up rollers to advance the cards out of the feed roller, and a clutch mechanism for disengaging the feed roller from the drive mechanism as the card comes into contact with the speed up rollers.

Claims

1. A method of delivering playing cards, the method comprising providing a playing card delivery apparatus comprising a card loading area, a playing card receiver and a delivery tray;

placing a group of cards in the card loading area;

shuffling the playing cards by moving the first playing card from a group of playing cards in the card loading area to the playing card receiver, wherein each playing card is moved to only one playing card receiver in shuffling the group of playing cards;

creating a displacement between a subsequent playing card that will be moved from the group of playing cards in the card loading area and the playing card receiver;

moving at least a second playing card from the group of playing cards in the card loading area after creating the displacement;

directly delivering from the playing card receiver to the delivery tray a number of playing cards comprising at least the first and second playing cards to form a deliverable hand of playing cards consisting of all cards present in the delivery tray;

removing the entire deliverable hand of playing cards from the delivery tray and delivering all playing cards to hand positions at a gambling table in groups of the deliverable cards;

sensing a removal of the number of playing cards from the delivery tray; and

subsequently delivering at least one additional number of playing cards from the card receiver to the delivery tray from which multiple cards may be manually removed from the delivery tray at a same time.

2. The method of claim 1 wherein the number of playing cards is exactly equal to the additional number of playing cards.

3. The method of claim 2 wherein the number of playing cards is exactly equal to the final number of playing cards in a partial hand or a final hand.

4. The method of claim 1 wherein the sensing is an automatic sensing and the subsequent delivering is an automatic delivering in response to the sensing.

5. The method of claim 1 wherein the playing card receiver comprises at least one hand-forming compartment in which an exact number of cards for a partial hand or complete hand is formed.

6. The method of claim 1 wherein the playing card receiver comprises a plurality of hand-forming compartments in which an exact number of cards for a partial hand or complete hand is formed in multiple compartments.

7. The method of claim 1 wherein the number of playing cards, consisting of all cards in the playing card receiver, are delivered at the same time.

8. The method of claim 1 wherein individual playing cards are delivered to provide the first number of playing cards.

9. The method of claim 1 wherein the displacement is non-rotational.

10. The method of claim 1 wherein the displacement is rotational.

11. The method of claim 1 wherein the displacement is substantially linear.

12. The method of claim 1 wherein moving the first playing card and the second playing card is done using a playing card moving mechanism.

13. The method of claim 1 wherein creating the displacement comprises moving the card receiver relative to the card moving mechanism and there are at least eight card receiver compartments.

14. The method of claim 1 wherein creating the displacement comprises moving the card moving mechanism relative to the card receiver and there are at least eight card receiver compartments.

15. The method of claim 1 wherein the displacement is vertical.

16. The method of claim 1 wherein the group is a hand or partial hand of playing cards.

17. A method of delivering playing cards, the method comprising:

providing a playing card delivery apparatus comprising a card loading area, a playing card receiver and a delivery tray;

placing a group of cards in the card loading area;

moving the first playing card from a group of cards in the card loading area to the playing card receiver;

b. creating relative movement between the group of playing cards in the card loading area and the playing card receiver;

moving at least a second playing card from the group of playing cards after creating the relative movement;

directly delivering all cards in the playing card receiver from the playing card receiver to the delivery tray all cards comprising playing cards comprising at least the first and second playing cards;

sensing a removal of all playing cards from the delivery tray; and

subsequently delivering at least one additional number of playing cards comprising all cards in a playing card receiver from the playing card receiver to the delivery tray from which multiple cards may be manually removed from the delivery tray at a same time.

18. The method of claim 17, wherein the playing card receiver comprises at least one hand-forming compartment.

19. The method of claim 17, wherein the playing card receiver comprises at least eight hand-forming compartments.

20. The method of claim 17, wherein the number of playing cards are delivered at the same time.

21. The method of claim 17 wherein individual playing cards are delivered to provide the first number of playing cards.

22. The method of claim 17, wherein the displacement is non-rotational.

23. The method of claim 17 wherein the displacement is rotational.

24. The method of claim 17 wherein the displacement is substantially linear.

25. The method of claim 17, wherein moving the first card and the second card is done using a card moving mechanism.

26. The method of claim 17, wherein creating the displacement comprises moving the card receiver relative to the card moving mechanism and there are at least eight card receiver compartments.

27. The method of claim 17 wherein creating the displacement comprises moving the playing card moving mechanism relative to the playing card receiver and there are at least eight card receiver compartments.

28. A method of delivering groups of playing cards, the method comprising:

providing a playing card delivery apparatus comprising a card loading area, at least eight playing card staging areas and a receiving tray;

placing an unrandomized group of playing cards in the card loading area;
