Abstract

A card-shuffling device reads a suit and value of individual cards that are moved through a card shuffler. Reading of the cards is effected after the cards have been received into a card holding area and before the cards have been delivered into a card collection area from which cards are removed from the card-shuffling device for use. The read suit and rank are then sent to a processor, wherein the processor identifies whether any playing card is a playing card that should be rejected from the card shuffler and the card shuffler then rejecting that playing card from the playing card shuffler.

Claims (47)

1. A playing card handling device, comprising:

a playing card holding area and a playing card collecting area;

a magazine configured to temporarily store playing cards between the playing card holding area and the playing card collecting area to form a set of playing cards in the playing card collecting area;

a reject mechanism positioned between the playing card holding area and the magazine, the reject mechanism being configured to reject a playing card before it is delivered to the magazine;

a sensor between the playing card holding area and the playing card collecting area,

wherein the sensor is configured to read suit and rank of each playing card between the playing card holding area and the playing card collecting area;

a processor operatively connected to the sensor and the reject mechanism, wherein the processor is configured to receive the read suit and rank information from the sensor;

wherein the processor is programmed to identify whether any playing card is a playing card that should be rejected and to cause the reject mechanism to reject that playing card from the playing card handling device; and

a display operatively connected to the processor, the processor being programmed to cause the display to display at least the read suit and rank of each playing card rejected from the playing card handling device.

2. The device of claim 1 , wherein the playing card handling device is a playing card shuffler or a playing card collator.

3. The device of claim 2 , wherein each read card is moved into a storage space of a plurality of storage spaces in the magazine after reading.

4. The device of claim 2 , wherein cards inserted into the magazine are discharged into the card collecting area to form a pack of shuffled cards.

5. The device of claim 2 , wherein the processor is programmed with a random number generator to randomly allocate a read card to a storage space of a plurality of storage spaces in the magazine.

6. The device of claim 2 , wherein the processor is programmed to sort a read card into a predetermined storage space of a plurality of storage spaces in the magazine.

7. The device of claim 2 , wherein the magazine comprises a plurality of magazines.

8. The device of claim 2 , wherein the processor is further programmed to cause the display to display the suit and rank of a missing card.

9. The device of claim 2 , wherein the processor is further programmed to identify a playing card for rejection by identifying the playing card as an oversupplied card.

10. The device of claim 9 , wherein each card is read before being inserted into a storage space of a plurality of storage spaces of the magazine.

11. The device of claim 9 , wherein cards inserted into the magazine are discharged into the card collecting area to form a pack of shuffled cards.

12. The device of claim 1 , wherein the reject mechanism comprises an air blaster playing card rejector in information communication with the processor.

13. The device of claim 1 , wherein the reject mechanism comprises an electromechanical playing card rejector in information communication with the processor.

14. The device of claim 1 , wherein cards inserted into the magazine are discharged into the card collecting area to form a pack of shuffled cards.

15. An automatic playing card shuffler, comprising:

a playing card holding area;

a playing card randomization area;

a playing card transfer mechanism that moves cards from the card holding area to the playing card randomization area;

a playing card reading mechanism located between the playing card holding area and the playing card randomization area that is capable of reading rank and suit of playing cards;

a reject mechanism positioned between the playing card holding area and the playing card randomization area, the reject mechanism being configured to reject a playing card before it is delivered to the playing card randomization area; and

a display device configured to display rank and suit of playing cards,

wherein the reading mechanism is configured to send the suit and rank of playing cards to a processor in information communication with the reading mechanism;

wherein the processor is programmed to identify whether any playing card is a playing card that should be rejected from the card shuffler and to cause the reject mechanism to reject that playing card from the playing card shuffler.

16. The device of claim 15 , wherein the display device is selected from the group consisting of an LCD and an LED display.

17. The device of claim 15 , wherein the processor is programmed to cause the display device to display rank and suit of each card read by the playing card reading mechanism.

18. An automatic playing card shuffler, comprising:

a playing card infeed area;

a playing card shuffling mechanism;

a shuffled playing card discharge area;

a microprocessor programmed to control operation of the playing card shuffler;

a first playing card feeder that transfers cards from the card infeed area to the playing card shuffling mechanism;

a second playing card feeder that transfers cards from the playing card shuffling mechanism to the shuffled playing card discharge area;

a sensor configured to read rank and suit of playing cards located within the playing card shuffler;

a reject mechanism positioned between the playing card infeed area and the first and second playing card feeders, the reject mechanism being configured to reject a playing card before it is delivered to one of the first and second playing card feeders; and

a display unit configured to display rank and suit of playing cards,

wherein the sensor is configured to send the read suit and rank of each card to the microprocessor, and

wherein the microprocessor is programmed to identify whether any playing card is a playing card that should be rejected from the playing card shuffler and to cause the reject mechanism to reject that playing card from the playing card shuffler.

19. The device of claim 18 , wherein the sensor is positioned between the card infeed area and the card shuffling mechanism.

20. The device of claim 18 , wherein the processor is configured to cause the display unit to display rank and suit of each card read by the card reading mechanism.
