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 the same quantity 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.

6. The apparatus of claim 5 wherein the microprocessor controls positioning of cards being inserted into card-receiving surfaces so that a card will strike only one of the upward deflecting surface and the downward deflecting surface of the acute edge of the separator.

7. The apparatus of claim 6 wherein the card moving mechanism is movable with respect to a stationary rack of card-receiving compartments.

8. The apparatus of claim 2 wherein both the card moving mechanism and the plurality of card-receiving compartments are movable in a vertical direction.

10. The apparatus of claim 1 wherein each card-receiving compartment comprises a set of cards selected from the group consisting of players'"'"' hands, dealer'"'"'s hands, discards, and excess cards.

11. The apparatus of claim 3 wherein both the card moving mechanism and the plurality of card-receiving compartments are movable in a vertical direction.

12. The apparatus of claim 3 wherein the plurality of card-receiving compartments is movable.

13. The apparatus of claim 1 wherein all cards received within the card-receiving compartments are associated into a shuffled deck.

14. The apparatus of claim 1 wherein the separator has two card contacting surfaces, one on a first face of the acute edge and the other on another face of the acute edge, an upward deflecting surface and a downward deflecting surface.

15. The apparatus of claim 14 wherein a card being moved into a card-receiving compartment may contact either the upward deflecting surface or a downward deflecting surface of the acute edge of the separator.

16. The apparatus of claim 15 wherein the microprocessor controls positioning of cards being inserted into card-receiving surfaces so that a card will strike only one of the upward deflecting surface and the downward deflecting surface of the separator.

17. The apparatus of claim 16 wherein the card moving mechanism is movable with respect to a stationary rack of card-receiving compartments.

18. The apparatus of claim 1 wherein the card moving mechanism comprises at least one roller and the at least one roller is movable with respect to a stationary rack of card-receiving compartments.

19. The apparatus of claim 1 wherein both the card moving mechanism and the plurality of card-receiving compartments are movable in a vertical direction.

20. The apparatus of claim 1 wherein the plurality of card-receiving compartments is movable.

21. An apparatus for handling cards comprising:

a shuffling chamber having a plurality of card-receiving compartments,

each card-receiving compartment is in a fixed relationship to adjacent card-receiving compartments,

each compartment is able to receive more than one card within an opening of the card-receiving compartment,

a card moving mechanism is positioned for moving at least one card at a time into a card-receiving compartment,

a mechanism that moves the card moving mechanism and the shuffling chamber relative to each other so that cards moved by the card moving mechanism are aligned for delivery into a card receiving compartment, and

a microprocessor for controlling card movement

wherein a separator is between each adjacent card-receiving compartment, and there is an edge of the separator that a card moved into card-receiving compartments contacts before that card is fully inserted into a card-receiving compartment and wherein separators are able to alter the card'"'"'s angle relative to a direction of card movement when cards are inserted into card-receiving compartments.

22. An apparatus for handling cards comprising:

a shuffling chamber having a plurality of card-receiving compartments,

each card-receiving compartment is in a fixed relationship to adjacent card-receiving compartments,

each compartment is able to receive more than one card within an opening of the card-receiving compartment,

a card moving mechanism is positioned for moving at least one card at a time into a card-receiving compartment,

a mechanism that moves the card moving mechanism and the shuffling chamber relative to each other so that cards moved by the card moving mechanism are aligned for delivery into a card receiving compartment, and

a microprocessor for controlling card movement wherein the card moving mechanism moves only one card at a time into a card-receiving compartment wherein a separator is between each adjacent card-receiving compartment, and there is an edge of the separator that a card moved into card-receiving compartments contacts before that card is fully inserted into a card-receiving compartment and wherein separators are able to alter the card'"'"'s angle relative to a direction of card movement when cards are inserted into card-receiving compartments.

23. An apparatus for handling cards comprising:

a shuffling chamber having a plurality of card-receiving compartments,

each card-receiving compartment is in a fixed relationship to adjacent card-receiving compartments,
