Abstract

Card-handling devices include a card-holding area and a card output shoe. The card output shoe includes a card-way for passage of cards from the card-holding area into a dealing-ready area. A movable gate is positioned between the card-way and the dealing-ready area to prevent cards in the dealing-ready area from re-entering the card-way. Card shufflers include a gate mounted to allow movement of randomized groups of cards from card-receiving compartments to proximate a terminal end plate of a card output shoe and to block movement of cards in an opposite direction. In related methods of moving cards, card movement through the card-way to the dealing-ready position is allowed by a movable gate and card movement from the dealing-ready position into the card-way is prevented by the movable gate.

Claims

1. A method for shuffling cards with a card shuffling apparatus having a first card receiver, a plurality of card receiving compartments movable relative to the first card receiver, and a second card receiver, the method comprising:

randomly selecting a card receiving compartment of the plurality of card receiving compartments;

moving at least one card from the first card receiver to the selected compartment, wherein at least one card is movable into an empty compartment and when there is already a card in the selected compartment;

maintaining a rolling count of a number of cards in each card receiving compartment of the plurality of card receiving compartments; and

authorizing an unloading of the selected compartment to the second card receiver only if the selected compartment has received at least a predetermined minimum number of a plurality of cards.

2. The method of claim 1, further comprising unloading the selected compartment to the second card receiver cards comprising pushing cards within the selected compartment with a card-unloading pusher comprising a flexible pusher arm and an enlarged head end portion.

3. The method of claim 2, wherein unloading the selected compartment to the second card receiver comprises driving the flexible pusher arm with a pinion gear operably engaged with the flexible pusher arm.

4. The method of claim 1, wherein unloading the selected compartment to the second card receiver when the selected compartment has received a predetermined number of cards comprises unloading the selected compartment to the second card receiver when the selected compartment has received at least between 4 and a maximum of 7 cards.

5. The method of claim 1, wherein moving at least one card from the first card receiver to the selected compartment comprises hitting a beveled edge of a plate-like shelf member defining the selected compartment with a leading edge of the at least one card.

6. The method of claim 1, wherein authorizing an unloading of the selected compartment to the second card receiver only if the selected compartment has received at least a predetermined minimum number of a plurality of cards comprises receiving, at a microprocessor, a signal from a sensor of the second card receiver that the second card receiver has a predetermined minimum number of cards.

7. The method of claim 1, further comprising:

randomly selecting a card receiving compartment of the plurality of card receiving compartments, which has been authorized for unloading; and

unloading the authorized selected compartment to the second card receiver.

8. A rack assembly for use in an automatic card shuffler, the rack assembly comprising:

card receiving compartments configured to receive cards one by one from a group of cards, wherein each of the card receiving compartments is sized to receive more than one card;

wherein each of the card receiving compartments comprises a plate member including a beveled surface oriented and positioned to be hit by a leading edge of a card upon receipt of the card into the card receiving compartment from the group of cards, wherein a microprocessor is configured to select the position of the rack assembly relative to the cards being received in the card receiving compartments, and wherein the beveled surface is located on a same side of the plate member in each of the card receiving compartments.

9. The rack assembly of claim 8, wherein an angle of the beveled surface is between about fifteen and about twenty degrees from a plane in which the plate member extends.

10. The rack assembly of claim 8, wherein the beveled surface is located on a bottom of the plate member in each of the card receiving compartments.

11. The rack assembly of claim 8, wherein the card receiving compartments are arranged in a stack.

12. The rack assembly of claim 11, further comprising an elevator configured to move the stack of card receiving compartments relative to the group of cards.

13. The rack assembly of claim 8, wherein each of the card receiving compartments is sized to receive up to fourteen cards.

14. The rack assembly of claim 8, wherein each of the card receiving compartments is sized to receive a maximum of at least ten cards.

15. A method for shuffling cards with a card shuffling apparatus having a first card receiver, a plurality of card receiving compartments, and a second card receiver, the method comprising:

selecting a card receiving compartment to receive at least one card from the first card receiver;

moving the at least one card from the first card receiver to the selected

compartment by hitting a beveled surface of a plate member defining the selected compartment with a leading edge of the at least one card; and

authorizing an unloading of the selected compartment to the second card receiver only if the selected compartment has received at least a predetermined minimum number of a plurality of cards.

16. The method of claim 15, wherein selecting a card receiving compartment to receive at least one card comprises randomly selecting the card receiving compartment with a microprocessor.

17. The method of claim 15, wherein moving the at least one card from the first card receiver to the selected compartment comprises moving the at least one card to a position on top of at least one other card already in the selected compartment.

18. The method of claim 15, wherein authorizing an unloading of the selected compartment to the second card receiver only if the selected compartment has received at least a predetermined minimum number of cards comprises authorizing an unloading of the selected compartment to the second card receiver only if the selected compartment has received at least four cards.

19. A rack assembly for use in an automatic card shuffler, the rack assembly comprising:

card receiving compartments, wherein each compartment of the card receiving compartments is sized and configured to receive more than one card, and wherein each of the card receiving compartments comprises a plate member that includes a beveled surface, wherein a microprocessor is configured to select the position of the rack assembly relative to the cards being received in the card receiving compartments, and wherein the beveled surface is located on a same side of the plate member in each of the card receiving compartments.

20. The rack assembly of claim 19, wherein the beveled surface of the plate member of each of the card receiving compartments is positioned on a same side of the plate member as respective plate members of the other card receiving compartments.

21. The rack assembly of claim 19, wherein the plate members of each of the card receiving compartments are substantially equally spaced from each other.

22. A method for shuffling cards with a card shuffling apparatus having a first card receiver, a plurality of card receiving compartments movable relative to the first card receiver, and a second card receiver, the method comprising:

randomly selecting a card receiving compartment of the plurality of card receiving compartments;

moving at least one card from the first card receiver to the selected compartment, wherein at least one card is movable into an empty compartment and is movable when there is already a card in the selected compartment; and

unloading the selected compartment to the second card receiver when the selected compartment has received at least a predetermined minimum number of cards by pushing cards within the selected compartment with a card-unloading pusher comprising a flexible pusher arm and an enlarged head end portion.
