Abstract

Claims (35)

1. A method of altering an orientation of cards being shuffled in an automatic card shuffler, comprising:

providing an automatic card shuffler with a user display; a card intake, a card outlet, a card shuffling apparatus, a card path between the card intake and the card outlet, a card-imaging system, at least one processor configured to control the card-imaging system, the user display, and to operate the card shuffler, wherein the card shuffling apparatus comprises multiple compartments;

receiving a plurality of cards in the card intake, the cards arranged in a stack wherein cards are arranged with card faces in a face to back orientation;

automatically feeding each card individually from the stack along the card path and inserting the card into one of the multiple compartments of the card shuffling apparatus;

reading card face information of each card as the card is being fed with the card-imaging system;

identifying unreadable cards, wherein unreadable cards include cards that lack card face information from the card-imaging system;

inserting the unreadable cards into at least one designated compartment in the card shuffling apparatus;

randomly inserting each card not identified as unreadable into a randomly selected compartment;

unloading all cards except the cards in the at least one designed compartment into the card outlet, forming a stack of cards, wherein each card in the stack of cards is oriented in the face-to-back orientation;

unloading the unreadable cards from the at least one designated compartment and adding the unreadable cards to an end of the stack after unloading all other cards;

causing the user display to display an alert indicating that at least one card in the outlet requires at least one of inspection or reorientation;

accepting at least one reoriented card from the card outlet in the card intake;

automatically feeding each card of the at least one reoriented card in the card intake into the card shuffler;

unloading the at least one reoriented card in the card shuffler to the card outlet; and

combining the at least one reoriented card with the stack of cards in the card outlet to form a shuffled set of cards in the face-to-back orientation.

2. The method of claim 1 , further comprising feeding at least some of the plurality of cards into the card shuffling apparatus comprising a carousel with a plurality of radially aligned compartments configured to receive more than one card.

3. The method of claim 1 , further comprising individually feeding the plurality of cards along a card path in a face-down orientation.

4. The method of claim 1 , further comprising stacking at least some of the plurality of cards in a substantially horizontal stack, with card faces in a substantially vertical plane.

5. The method of claim 1 , further comprising shuffling between 8 and 10 decks of cards with the card shuffling apparatus.

6. A method of detecting unreadable cards with a card-handling device, the card-handling device including a card intake, a card output, a playing card-shuffling apparatus positioned along a card path through the card-handling device, and a card-imaging system positioned along the card path, the method comprising:

receiving, via the card intake, playing cards;

randomizing, by the playing card-shuffling apparatus, at least some of the playing cards, the playing card-shuffling apparatus comprising multiple compartments;

imaging, by the card-imaging system, a surface of the playing cards;

recognizing, by the card-imaging system, card face information and identify one or more unreadable playing cards, wherein the one or more unreadable playing cards comprise playing cards that do not include card face information on the surface of the playing cards oriented toward the card-imaging system;

receiving, by the playing card-shuffling apparatus, the one or more unreadable playing cards in at least one designated compartment selected from the multiple compartments; and

unloading all the playing cards except the one or more unreadable playing cards in the at least one designated compartment into the card output; forming a stack of playing cards, in the card output;

unloading the unreadable playing cards from the at least one designated compartment and adding the unreadable playing cards to an end of the stack of playing cards after unloading all other playing cards; and

providing, by the card output at least one of the playing cards.

7. The method of claim 6 , further comprising providing, by the card-handling device, the one or more unreadable playing cards for reorientation.

8. The method of claim 7 , further comprising combining, by the card-handling device, the one or more unreadable playing cards with the stack of playing cards after reorientation.

9. The method of claim 6 , further comprising shuffling, by the card-shuffling apparatus, the playing cards that are not designated as the one or more unreadable playing cards.

10. The method of claim 9 , further comprising combining, by the card-handling device, the one or more unreadable playing cards with the shuffled playing cards after the one or more unreadable playing cards have been reoriented.

11. The method of claim 6 , wherein the playing card-shuffling apparatus comprises a carousel and the multiple compartments are oriented radially about the carousel.

12. The method of claim 6 , wherein at least one processor associated with the card-handling device is configured to control operation of the playing card-shuffling apparatus and the card-imaging system.

13. The method of claim 6 , further comprising alerting, by a display associated with the card-handling device, a user when the unreadable playing cards are detected.
