wherein the card output mechanism comprises a movable ejector configured to simultaneously eject cards out from two or more card storage compartments of the movable rack.
2. The automatic card shuffler of claim 1 , wherein the movable ejector is configured to simultaneously eject cards out from all card storage compartments of the movable rack.
3. The automatic card shuffler of claim 1 , wherein each card storage compartment is sized and configured to hold two cards therein and to prevent insertion of more than two cards therein.
4. The automatic card shuffler of claim 1 , further comprising a card reading system configured to acquire data from one or more images of cards moving through the card input mechanism and toward the card storage device and to identify one or more distinguishing characteristics of the cards comprising at least one of rank and suit using the acquired data from the one or more images.
5. The automatic card shuffler of claim 1 , wherein the movable ejector is configured to move horizontally within the automatic card shuffler.
6. The automatic card shuffler of claim 5 , wherein the movable ejector is elongated and extends vertically alongside the cards in the card storage device as the movable ejector moves horizontally within the automatic card shuffler to eject cards out from two or more card storage compartments of the movable rack.
7. The automatic card shuffler of claim 1 , wherein the movable ejector is configured to be located on a side of the movable rack adjacent the card input mechanism while cards move from the card input mechanism into the card storage compartments of the movable rack.
8. The automatic card shuffler of claim 1 , wherein the movable ejector is sized and configured to prevent cards within the movable rack from moving out from the first side of the movable rack as the movable rack moves within the automatic card shuffler as additional cards are inserted into the card storage compartments of the movable rack.
9. The automatic card shuffler of claim 1 , further comprising a control system programmed to randomly select a location for each card moving through the card input mechanism, and to align the movable rack relative to the card input mechanism such that each card moving through the card input mechanism is inserted into the respective randomly selected location for each card.
10. The automatic card shuffler of claim 9 , wherein the control system is further programmed to control operation of components of the card input mechanism, the card storage device, and the card output mechanism.
11. An automatic card shuffler, comprising:
a card input mechanism for inputting cards into the automatic card shuffler;
a card storage device for receiving cards from the card input mechanism and temporarily storing cards within the automatic card shuffler, the card storage device including a movable rack configured to move within the automatic card shuffler, the movable rack comprising a plurality of card storage compartments, each card storage compartment sized and configured to hold at least one card therein; and
a card output mechanism for receiving a stack of shuffled cards from the card storage device and outputting the stack of shuffled cards from the automatic card shuffler, the card output mechanism comprising a movable ejector configured to simultaneously eject cards out from two or more card storage compartments of the movable rack, wherein the movable ejector is disposed on a first side of the movable rack as unshuffled cards are inserted into the movable rack by the card input mechanism, and wherein the movable ejector moves from the first side of the movable rack to an opposing second side of the movable rack to eject cards out from the two or more card storage compartments of the movable rack.
12. The automatic card shuffler of claim 11 , wherein the movable ejector is sized and configured to prevent cards within the movable rack from moving out from the first side of the movable rack as the movable rack moves within the automatic card shuffler as additional cards are inserted into the card storage compartments of the movable rack.
13. The automatic card shuffler of claim 12 , wherein the movable ejector is configured to move horizontally within the automatic card shuffler.
14. The automatic card shuffler of claim 13 , wherein the movable ejector is elongated and extends vertically alongside the cards as the movable ejector moves horizontally within the automatic card shuffler to eject cards out from two or more card storage compartments of the movable rack.
15. A method of shuffling cards using an automatic card shuffler, comprising:
inputting cards into an automatic card shuffler using a card input mechanism;
temporarily storing two or more cards in each of a plurality of card storage compartments in a movable rack of a card storage device within the automatic card shuffler;
simultaneously ejecting cards out from the plurality of card storage compartments using a movable ejector to form a stack of shuffled cards; and
outputting the stack of shuffled cards from the automatic card shuffler using a card output mechanism.
16. The method of claim 15 , further comprising inserting no more than two cards into each of the plurality of card storage compartments.
17. The method of claim 15 , further comprising reading at least a portion of images of cards moving through the card input mechanism using a card reading system and identifying one or more distinguishing characteristics of the cards using the at least a portion of images.
18. The method of claim 15 , wherein ejecting cards out from the plurality of card storage compartments comprises simultaneously ejecting cards out from the plurality of card storage compartments using the movable ejector to form the stack of shuffled cards.
19. The method of claim 18 , further comprising maintaining the movable ejector on a side of the movable rack adjacent the card output mechanism while cards are inserted into the plurality of card storage compartments.
20. The method of claim 15 , further comprising:
maintaining the movable ejector on a first side of the movable rack as cards are inserted into the movable rack by the card input mechanism; and
moving the movable ejector from the first side of the movable rack to an opposing second side of the movable rack and back to the first side of the movable rack to simultaneously eject groups of cards out from the plurality of card storage compartments to form the stack of shuffled cards.
21. The method of claim 15 , further comprising preventing cards within the movable rack from moving out from the first side of the movable rack as the movable rack moves within the automatic card shuffler as additional cards are inserted by the card input mechanism into the card storage compartments of the movable rack.
