Abstract

A card shuffling device reads suit and value of individual cards that are moved through the card shuffler. Reading of the cards is effected after cards have been received into a card holding area and before cards have been delivered into a card collection area from which cards are removed from the device for use.

Claims

1. A card shuffler having a card holding area and a card collecting area,

the card shuffler being capable of moving cards between the card holding area and the card collecting area to form a shuffled set of cards in the card collecting area,

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

the sensor reading suit and rank of each card individually between the card holding area and the card collecting area, wherein a display on the card shuffler displays suit and rank of a card read by the sensor.

2. The card shuffler of claim 1 wherein the suit and rank of a card displayed is the suit and rank of a missing or oversupplied card.

3. The card shuffler of claim 1 further comprising a computer that determines whether cards have been removed or added to cards inserted into the card holding area that have been retrieved from the playing table.

4. An automatic card shuffler, comprising:

a card holding area;

a card randomization area;

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

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

a display device on the card shuffler capable of displaying rank and suit of cards.

5. The device of claim 4, where the device capable of displaying rank and suit is selected from the group of an LCD and an LED display.

6. The device of claim 4 wherein the display device is capable of displaying rank and suit read by the card reading mechanism.

7. The automatic card shuffler of claim 4 wherein the suit and rank of a card displayed is the suit and rank of a missing card.

8. An automatic card shuffler, comprising:

a card infeed area;

a card shuffling mechanism;

a shuffled card discharge area;

a microprocessor programmed to control operation of the card shuffler;

a first card feeder that transfers cards from the card in-feed area to the card shuffling apparatus;

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

a sensor capable of reading rank and suit located within the card shuffler; and

a display unit on the automatic card shuffler that displays rank and suit of cards.

9. The apparatus of claim 8 wherein the sensor is positioned between the card in-feed area and the card shuffling mechanism.

10. The device of claim 8 wherein the display device is capable of displaying rank and suit read by the card reading mechanism.

11. The device of claim 9 wherein the display device is capable of displaying rank and suit read by the card reading mechanism.

12. The automatic card shuffler of claim 8 wherein the suit and rank of a card displayed is the suit and rank of a missing card.
