Abstract

Apparatuses and methods 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 may comprise 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. Apparatuses for feeding cards may comprise 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 (17)

1. A method of randomizing cards, comprising:

providing a card infeed area;

providing a plurality of card receiving compartments, each compartment configured for receiving at least two cards;

randomly assigning cards in the card infeed area to card receiving compartments;

moving a randomly selected card receiving compartment to align the compartment with a card feeder;

feeding individual cards from the card infeed area into a selected, aligned compartment, and when the selected compartment is occupied by a first card, aligning the selected card receiving compartment such that a second card is impacted against a deflecting surface to insert the second card under the first card; and

removing cards from a card receiving compartment to form a shuffled group of at least two cards.

2. The method of claim 1 , wherein the plurality of card receiving compartments is arranged in a vertical stack.

3. The method of claim 1 , wherein the plurality of card receiving compartments is arranged in a carousel.

4. The method of claim 1 , further comprising accepting a group of cards to be shuffled.

5. The method of claim 1 , further comprising randomly assigning each card in the card infeed area to a compartment prior to feeding a first card.

6. The method of claim 1 , further comprising impacting a third card against a downward deflecting surface to insert the third card over the first card.

7. The method of claim 6 , wherein impacting the second card against the deflecting surface comprises bending the second card.

8. The method of claim 1 , further comprising removing all groups of cards positioned in the compartments.

9. The method of claim 8 , further comprising stacking all of the groups of removed cards to form a shuffled deck.

10. The method of claim 1 , wherein the at least two cards are randomly inserted into the compartment.

11. The method of claim 1 , wherein aligning the selected card receiving compartment such that the second card is impacted against the deflecting surface to insert the second card under the first card comprises aligning the selected card receiving compartment such that the second card is impacted against an upward deflecting surface to insert the second card under the first card.
