Abstract

The present invention provides an apparatus and method for moving playing cards from a first group of cards into plural hands of cards, wherein each of the hands contains a random arrangement of cards. The apparatus comprises a card receiver for receiving the first group of cards, a single stack of card-receiving compartments generally adjacent to the card receiver, the stack generally vertically movable, an elevator for moving the stack, a card-moving mechanism between the card receiver and the stack, and a microprocessor that controls the card-moving mechanism and the elevator so that an individual card is moved into an identified compartment. The number of compartments receiving cards and the number of cards moved to each compartment may be selected. An apparatus for feeding cards, comprising a surface for supporting a stack of cards, a feed roller with a frictional outer surface, a drive mechanism for causing rotation of the feed roller, a pair of speed-up rollers to advance the cards out of the feed roller, and a clutch mechanism for disengaging the feed roller from the drive mechanism as the card comes into contact with the speed up rollers.

Claims

1. An automatic card shuffler comprising:

a card infeed area;

a card feeder capable of moving cards from the card infeed area to the card shuffling mechanism;

a single delivery tray from which all cards are removed during a shuffling and dealing process;

a card removing device, the device moving the at least one random hand of cards into the delivery tray,

a user display capable of displaying at least alpha-numeric information;

a user input device for receiving game selections; and

a microprocessor programmable to control operation of the shuffler;

including displaying the game selections on the user display in alphanumeric form and to control delivery of hands to the single delivery tray according to game selection.

2. The shuffler of claim 1, wherein the game information is selected from the group consisting of game names, and numbers of cards per hand.

3. The card shuffler of claim 1, and further comprising a display in communication with the microprocessor for displaying a menu of game information.

4. The device of claim 1, wherein the card shuffling mechanism comprises a plurality of compartments, each compartment capable of receiving at least one card from the card infeed area.

5. The device of claim 4, wherein the card feeder moves cards individually from the card infeed area to the delivery tray.

6. The device of claim 5, wherein the card-removing device removes a hand of randomized cards from a compartment and delivers the hand to the delivery tray.

7. An automatic card shuffler comprising:

a card infeed area, the area accepting a group of cards to be randomized;

a card feeder capable of moving cards from the card infeed area to a shuffling mechanism;

a card shuffling mechanism, whereby an order of fed cards is randomized, and at least a partial random hand of cards is provided to a single card delivery tray;

the delivery tray;

a microprocessor programmable to control operation of the shuffler; and

a user input device for selecting game information on the basis of the name of a game displayed on the user input device.

8. A method of delivering hands of cards to a card game, comprising:

providing a computer controlled card-shuffling device capable of randomizing cards and forming at least one hand of randomized cards, wherein the device further comprises a user input for selecting at least one of an identity of a game and a number of cards per hand and a user display capable of displaying at least alpha-numeric information;

loading a group of cards into the card-shuffling device;

selecting a game from a set of displayed alphanumeric game name identifiers;

displaying at least one of the selected game identifiers or a number of cards per hand based on the selected game; and

automatically delivering at least one hand of cards based on selecting a game identifier or a number of cards per band displayed.

9. The method of claim 8, wherein the shuffling device forms plural hands of cards.

10. The method of claim 8, wherein at least one of selected game and cards per hand is displayed on a display device in communication with the microprocessor.

11. An automatic card shuffler comprising:

a card infeed area;

a card shuffling apparatus;

a feed mechanism capable of moving cards from the card infeed area to the shuffling apparatus;

a game selection device capable of being set to operate in one of a plurality of selected game modes;

a user display capable of displaying a selected game mode in alpha-numeric form; and

a microprocessor capable of controlling the operation of the shuffler, controlling numbers of cards dealt upon selection of a game mode provided as an alphanumeric display and the user display.

12. The automatic card shuffler of claim 11, wherein the card shuffling apparatus comprises a plurality of shuffling compartments.

13. The automatic card shuffler of claim 11, wherein the selected game modes includes games with different numbers of cards per hand.

14. The automatic card shuffler of claim 11, further comprising an output tray and a second feed mechanism for moving cards from the shuffling apparatus to the output tray.

15. A method of delivering cards, the method comprising:

inputting on a user input device external to a shuffler a variable, user-selectable number of cards per hand by selecting a name of a game that requires a specific number of cards to be dealt to hands;

moving a first card from a group of cards to a card receiver;

delivering the inputted number of cards from the card receiver;

sensing a removal of the number of cards; and

moving at least a second card from the group of cards to the card receiver.

16. A card randomizing and delivery apparatus comprising:

a display showing game selection information;

a selector allowing input of a choice from displayed game selection information;

a card input area;

a first card feeder moving cards one at a time from the card input area into a card receiver;

a motor tat is able to create a displacement between the input area and the card receiver;

a delivery tray;

a second card feeder capable of providing cards from the card receiver one at a time to said delivery tray to form a hand of cards;

a sensor able to sense removal of a hand of cards from said delivery tray to trigger delivery of cards one at a time to form another hand in the same delivery tray; and

a microprocessor programmed to control the operation of the apparatus including to provide for (a) delivery of a hand of cards after sensed removal of a hand of cards from the delivery tray, (b) display of alphanumeric game selection information;

(c) control the motor; and

(d) acceptance of same selection choices inputted with the selector.

17. A method of delivering successive hands of cards from a single output tray of an apparatus comprising:

providing at least one deck of playing cards to an input area;

removing the first hand of cards from the output tray;

sensing the absence of cards in the output tray; and

providing cards from randomized cards in the apparatus to form a second at least partial hand of cards in the same output tray.
