Abstract

The present invention features a playing card shuffling device, which through the use of a small image capturing means, captures an image of the face value of each card and stores the image in memory. This image is sorted in the format of a bitmap image. The operator of the machine would be able to recall through the use of a keypad, the images of the cards that comprised the individual hands in the previous game. This feature allows for verification of a winning hand after a game has been completed. Thereby, a quick recheck of hands before playing a winning hand is performed. The face value of each card is determined by character recognition software. These card values would be stored in memory for archival access for use in monitoring the randomness of the game and determining the number of winnings hands.

Claims

1. A card shuffling apparatus comprising:

a housing;

a card input receptacle on the housing adapted to receive at least one deck of un-shuffled playing cards;

a shuffling mechanism supported by the housing and adapted to receive cards from said card input receptacle and for shuffling the cards;

a controller for controlling the operation of the shuffler, image capturing and display functions;

a card output bin;

card moving apparatus disposed within the housing configured for mechanically engaging an individual card from the cards shuffled by the shuffling mechanism and transporting plural cards individually within the housing from the shuffling mechanism to the card output bin to form a hand;

an image capturing device disposed within said housing for capturing image data of each individual card being transported by the card moving apparatus; and

a display mounted to the housing, wherein the display is capable of displaying a player hand image of the cards in a player hand, the player hand image comprising an image representing each card being transported.

2. The card shuffler apparatus of claim 1 further comprising:

a control panel, wherein the control panel is located on said housing, said control panel having keys in operative communication with said controller for selecting operation functions of the card shuffler.

3. The card shuffler apparatus of claim 2 wherein the display is located on said control panel.

4. The card shuffler apparatus of claim 2 wherein said controller comprises:

a microprocessor, a non-volatile memory storage means for storing digital image data of said playing cards and an image processing means for processing digital image data collected by said image capturing means.

5. The card shuffler apparatus of claim 1 further comprising embedded software for controlling operation of the image capturing device.

6. The card shuffler apparatus of claim 4 wherein said non-volatile memory storage means stores image data of multiple playing cards for a plurality of playing stations and a plurality of games.

7. The card shuffler apparatus of claim 1 wherein said image capturing device is a camera.

8. The card shuffler apparatus of claim 7 wherein said camera is a digital camera.

9. The card shuffler apparatus of claim 7 wherein said camera is a digital video camera.

10. The card shuffling apparatus of claim 1, further comprising a sensor for sensing the presence of a card transported by the card moving apparatus, wherein the image capturing device is further configured to respond to the sensor by capturing image data associated with the card transported by the card moving apparatus.

11. The card shuffling apparatus of claim 1, wherein the player hand image is an image of a current hand.

12. The card shuffling apparatus of claim 1, wherein the player hand image is an image of a historical hand.

13. The card shuffling apparatus of claim 1, wherein multiple current player hand images are displayed.

14. The card shuffling apparatus of claim 1, wherein multiple historical player hand images are displayed.

15. A method of shuffling playing cards for card games said method comprising the steps of:

a) placing un-shuffled cards into a card input receptacle of an automatic card shuffler for handling playing cards;

b) activating the card shuffler such that the cards are shuffled within the automatic card shuffler;

c) individually moving playing cards one at a time within the automatic card shuffler from the shuffled cards to a card output bin operatively associated with the automatic card shuffler until a hand of cards is formed;

d) capturing image data of each card as the card is being moved within the automatic card shuffler; and

e) displaying an image of a formed hand on a display associated with the shuffler, the player hand image comprising an image representing each card being transported.

16. The method of claim 15 further comprising storing the captured images.

17. The method of claim 15 further comprising displaying said captured images on a display on the automatic card shuffler.

18. The method of claim 15 further comprising displaying historical hand images on a display on said card shuffler.

19. The method of claim 17 wherein said processing step further comprises storing said image data of multiple playing stations for plurality of games played.

20. The method of claim 18 where in said step of displaying further includes displaying bitmap images on a liquid crystal display.

21. The method of claim 18 wherein said displaying step further comprises displaying hand information for multiple playing stations for a plurality of games played and verification of winning hands.
