Abstract

Automatic card shufflers include a card shuffling mechanism, a base at least partially supporting the card shuffling mechanism, a shoe to receive cards from the card shuffling mechanism, and a card imaging system configured to detect at least one indicia on the cards, the card imaging system being at least partially disposed within the base.

Claims

1. An automatic card shuffler, comprising:

a card infeed area;

a card shuffling mechanism positioned to receive cards from the card infeed area;

a card unloader configured to remove cards from the card shuffling mechanism;

a bottom support member having a first portion supporting the card shuffling mechanism;

a card imaging system configured to detect at least one indicia on the cards, the card imaging system supported by the bottom support member;

a shoe coupled to the bottom support member and positioned to receive cards from the card unloader;

a processor programmed to convert signals from the card imaging system into at least one of rank or suit information of the cards; and

a quick disconnect structure configured to removably couple the card shuffling mechanism to the shoe.

2. The automatic card shuffler of claim 1, wherein the processor is supported by the bottom support member.

3. The automatic card shuffler of claim 1, wherein the card shuffling mechanism comprises a plurality of card-storing compartments.

4. The automatic card shuffler of claim 3, wherein the card unloader is configured to transfer a group of cards from one compartment of the plurality of card-storing compartments of the card shuffling mechanism to the shoe.

5. The automatic card shuffler of claim 1, wherein the card shuffler is configured to transfer cards from the card shuffling mechanism to the shoe with the card unloader.

6. The automatic card shuffler of claim 1, wherein the card imaging system is positioned under a portion of the shoe.

7. The automatic card shuffler of claim 1, wherein the card imaging system comprises a camera and the processor, wherein the processor comprises an image-processing module.

8. The automatic card shuffler of claim 1, wherein the card imaging system is configured to scan each card individually removed from the shoe.

9. The automatic card shuffler of claim 1, wherein the card imaging system comprises a light board configured to illuminate the at least one indicia of the cards during imaging with the card imaging system.

10. An automatic card shuffler, comprising:

a card shuffling mechanism configured to randomize cards;

a shoe;

a lower support member coupled to the card shuffling mechanism with the card shuffling mechanism positioned over the lower support member, the shoe coupled to a portion of the lower support member and the lower support member configured to be placed on a surface of a gaming structure, the lower support member supporting a card imaging system configured to detect at least one indicia of the cards, the card imaging system positioned proximate a card output area of the shoe and configured to scan the cards dispensed from the shoe, wherein an upper portion of the shoe is positioned over the card imaging system; and

a quick disconnect structure configured to removably couple the card shuffling mechanism to the lower support member in communication with the shoe.

11. The automatic card shuffler of claim 10, wherein the card imaging system comprises a camera and an image-processing module.

12. The automatic card shuffler of claim 11, wherein the card imaging system further comprises a light board configured to illuminate the at least one indicia of the cards during imaging with the camera.

13. The automatic card shuffler of claim 10, further comprising a processor, the processor configured to convert signals from the card imaging system into at least one of rank or suit information of the cards.

14. An automatic card shuffler, comprising:

a lower support member supporting a card imaging system configured to detect at least one indicia of cards;

a shoe portion coupled to the lower support member, the shoe portion defining a card path extending over the card imaging system for imaging the cards as the cards pass along the card path, wherein the shoe portion comprises a finger insertion opening in a front cover plate for removing cards from the shoe portion, the finger insertion opening being offset from a center of the shoe portion to define a first larger side of the front cover plate bordering the finger insertion opening on a first side, the first larger side having a relatively larger area as compared to a second smaller side of the front cover plate bordering the finger insertion opening on a second side, the first larger side overlying the card imaging system and completely overlying a camera of the card imaging system; and

a card shuffling mechanism coupled to the lower support member and comprising a card infeed area configured to supply cards to the card shuffling mechanism and a card output area, wherein the shoe portion is positioned to receive shuffled cards from the card output area of the card shuffling mechanism.

15. The automatic card shuffler of claim 14, wherein the card imaging system comprises the camera and an image-processing module.

16. The automatic card shuffler of claim 15, wherein the camera and the image-processing module are mounted to the lower support member.

17. The automatic card shuffler of claim 16, wherein the card imaging system further comprises a light board mounted to the lower support member and configured to illuminate the at least one indicia of the shuffled cards during imaging with the camera.

18. The automatic card shuffler of claim 14, wherein the card shuffling mechanism comprises a plurality of card-storing compartments.

19. The automatic card shuffler of claim 18, further comprising a card unloader positioned and configured to transfer groups of cards from the plurality of card-storing compartments of the card shuffling mechanism to the shoe portion.

20. The automatic card shuffler of claim 14, wherein the card imaging system is positioned under the shoe portion.
