Abstract

A method and apparatus delivers subsets of randomly mixed playing cards from a first group of playing cards. At least one first group of multiple playing cards is provided to a playing card randomizing apparatus. Ar least one subset of randomized playing cards is formed within the apparatus from the first group of playing cards. A first subset of randomized playing cards for use in a card game is delivered to a single delivery tray. The first subset of playing cards delivered to the single delivery tray as a whole (all of the cards in the subset). At least one additional subset of playing cards is formed within the card randomization apparatus from remaining cards from the first group of playing cards. Upon manual removal of the first subset of playing cards from the single delivery tray, the apparatus delivers the at least one additional subset of randomly mixed playing cards into the single delivery tray as a second group of playing cards.

Claims

1. A method for delivering subsets of randomly mixed cards from a first group of cards, comprising:

providing at least one first group of multiple playing cards to a playing card randomization apparatus;

forming at least one subset of randomized playing cards within the apparatus from the first group of playing cards;

delivering to a single delivery tray a first at least one subset of randomized playing cards for use in a game, the first at least one subset of randomized playing cards being delivered to the delivery tray as a whole first at least one subset of randomized playing cards;

forming at least one additional subset of randomized playing cards within the apparatus from remaining playing cards from the at least one first group of playing cards; and

upon manual removal of the first at least one subset of randomized playing cards from the delivery tray, automatically delivering the at least one additional subset of randomized playing cards into the delivery tray as a second group.

2. The method of claim 1 wherein the playing card randomization apparatus comprises a plurality of adjacent card receiving compartments used to form the at least one subset of randomized playing cards and the at least one additional subset of randomized playing cards, and wherein at least one of the at least one subset of randomized playing cards and the at least one additional subset of randomized playing cards becomes units of cards in a card game wherein the units are selected from the group consisting of players'"'"' hands, dealer'"'"'s hands, partial hands, discards and excess cards.

3. The method of claim 2 wherein a separator is located between each adjacent card-receiving compartment, and there is an edge of the separator such that a playing card moved into playing card receiving compartments contacts the edge of the separator before that playing card is fully inserted into the card receiving compartment.

4. The method of claim 1 wherein the playing card randomization apparatus comprises a plurality of adjacent card receiving compartments used to form the at least one subset of randomized playing cards and the at least one additional subset of randomized playing cards, and wherein each of the at least one of the at least one subset of randomized playing cards and the at least one additional subset of randomized playing cards is used to form specific subsets selected from the group consisting of players'"'"' hands, dealer'"'"'s hands, partial hands, discards and excess cards.

5. The method of claim 1 wherein the card randomizing apparatus comprises a plurality of adjacent playing card-receiving compartments in a configuration selected from the group consisting of a carousel, a vertical mixing stack, and a fan shape.

6. The method of claim 1 wherein the first group of playing cards comprises one or more decks of playing cards.

7. The method of claim 6 wherein the total number of playing cards in at least some subsets of randomized playing cards delivered to the delivery tray consist of hands delivered from the card randomization apparatus, and the hands comprise a total number of playing cards that are less than the total number of cards in the first group of cards.

8. The method of claim 1 wherein each individual subset of randomly mixed playing cards is delivered to the delivery tray, and wherein the delivery tray can be accessed so that playing cards in the delivery tray can be contacted by a hand of a dealer.

9. The method of claim 1 wherein at least one, but less than all individual subsets of randomized playing cards, is a subgroup of the first group of cards that is delivered individually to the delivery tray.

10. The method of claim 1 wherein each individual subset of randomized playing cards is formed prior to a first subset of randomized playing cards is delivered to the delivery tray.

11. The method of claim 1 wherein the first group of playing cards is a single deck of playing cards or a double deck of playing cards.

12. The method of claim 11 wherein the single deck of playing cards is selected from the group consisting of a 52 card deck, a 52 card deck with one or more jokers, and a special deck.

13. An apparatus for delivering shuffled plural hands of playing cards in a card game, comprising:

a playing card in-feed tray capable of receiving a first group of playing cards to be shuffled;

a first card moving mechanism capable of delivering playing cards from the card in-feed tray to a playing card randomization apparatus;

the card randomization apparatus having at least one staging area for receiving subsets of randomized playing cards;

a single playing card receiving tray;

a second playing card moving mechanism capable of moving a subset of randomized playing cards from the at least one staging area to the single playing card receiving tray as a second group of playing cards;

a sensing mechanism for sensing at least a presence of playing cards in the single playing card receiving tray; and

a processor programmed to control the playing card randomization apparatus and the playing card moving mechanisms so that more than one subset of playing cards is delivered to the single playing card receiving tray, one subset at a time, during a single shuffling operation.

14. The apparatus of claim 13 wherein the processor is programmed to control the playing card randomization apparatus and the playing card moving mechanisms so that subsets of cards are delivered to the tray and only one subset of playing cards at a time is present in the single playing card receiving tray until a predetermined number of hands of playing cards are delivered to the single playing card receiving tray.

15. The apparatus of claim 13 wherein the at least one staging area comprises a plurality of staging areas.

16. The apparatus of claim 15 wherein the plurality of staging areas comprises a group of adjacent compartments in an arrangement selected from the group consisting of a rack, a carousel and a fan.

17. The apparatus of claim 16 further comprising a drive mechanism capable of moving the at least one card staging area relative to a stationary card in-feed tray during shuffling.

18. The apparatus of claim 17 wherein the drive mechanism comprises a motor, a drive belt and an elevator.

19. The apparatus of claim 15 wherein a first subset of playing cards is delivered to the single playing card receiving tray automatically after shuffling all playing cards in the first group of playing cards.

20. The apparatus of claim 19 wherein additional subsets of playing cards are delivered to the single playing card receiving tray on demand.

21. The apparatus of claim 20 wherein a subset of cards is delivered to the single playing card receiving tray for each player position.

22. The apparatus of claim 20 wherein the processor contains programming so that one more subset of playing cards is delivered than is needed for each player position and the dealer position.

23. The apparatus of claim 13 wherein the single playing card receiving tray is of a configuration that permits manual removal of playing cards as the second group of playing cards.

24. The apparatus of claim 13 wherein the sensing mechanism is an optical sensor.

25. The apparatus of claim 13 further comprising controls capable of instructing the processor to direct unloading of all playing cards in the apparatus.
