Abstract

Claims (44)

1. An apparatus for randomly arranging and dealing a plurality of playing cards, comprising:

a device for moving cards and randomly ejecting playing cards from an initial set of playing cards located in a card input unit for an initial delivery of randomly arranged playing cards to a card delivery unit;

a card collection unit; and

a playing card limiter that is adjustable to allow a greater number or a lesser number of playing cards to pass from the card delivery unit to the card collection unit;

wherein the card delivery unit includes upper powered rollers and lower powered belts for receiving and transporting the playing cards through the card delivery unit and into the card collection unit.

2. The apparatus of claim 1 , further comprising:

sensors located in the card collection unit and configured to detect the presence of playing cards in the card collection unit; and

a microprocessor in electrical communication with the sensors and configured to instruct the apparatus to randomly eject playing cards from the initial set of playing cards for a subsequent delivery to the card delivery unit when sensor outputs indicate all playing cards present in the card collection unit are removed from the card collection unit.

3. An apparatus for randomly arranging and dealing a plurality of playing cards, comprising:

a random card ejection unit for randomly arranging and ejecting a plurality of playing cards from a stack of playing cards;

a card separation unit for receiving the plurality of ejected cards, the plurality of ejected cards forming a new staggered card stack;

a stop arm placed rear of an adjustable ejected playing card limiter, the stop arm permitting access to the card separation unit; and

a card delivery unit for receipt and movement of successive bottom most playing cards separated from the new staggered card stack to a card collection unit;

wherein the card collection unit is configured for receipt of successively separated cards delivered by the card delivery unit.

4. The apparatus of claim 3 , wherein the stop arm has an angle of placement configured to cause the plurality of ejected cards to stack in a staggered fashion rear of the stop arm.

5. The apparatus of claim 3 , wherein the stop arm is configured to be raised for allowing one or more playing cards in the new staggered card stack to be advanced to the card separation unit.

6. The apparatus of claim 3 , wherein the adjustable ejected playing card limiter is an adjustable floating gate configured to prevent no more than three playing cards from being simultaneously advanced to the separation unit.

7. The apparatus of claim 3 , further comprising an audio system for generating voice outputs related to a status of the apparatus.

8. The apparatus of claim 7 , wherein the status of the apparatus includes at least one voice indication from the group consisting of a card jam indication, ready to shuffle indication, complete hand in the collection unit indication, remove cards in the collection unit indication and input cards indication.

9. The apparatus of claim 3 , wherein once a first predetermined number of cards are ejected, the random card ejection unit ceases operation until such time that the card delivery unit causes a second predetermined number of cards to be delivered to the card collection unit.

10. The apparatus of claim 3 , wherein the card separation unit comprises one or more rotating belts adjacent a card traveling surface for contacting a successive bottom most card in the new staggered card stack, the successive bottom most card being propelled forward under a floating gate and one or more upper separation feed rollers by the one or more rotating belts.

11. The apparatus of claim 10 , wherein a centerline of the one or more upper separation feed rollers is placed slightly forward of a centerline of a center separation belt pulley.

12. The apparatus of claim 3 , wherein the card delivery unit comprises one or more unpowered upper delivery feed rollers and one or more lower driven delivery feed rollers, the one or more upper and lower delivery feed rollers positioned near a forward end of one or more lower rotating belts of the card separation unit and the one or more lower driven delivery feed rollers are configured to rotate at a relative speed greater than the one or more lower rotating belts.

13. The apparatus of claim 12 , wherein the one or more lower delivery feed rollers and the one or more lower rotating belts are configured to be driven by a common motor.

14. The apparatus of claim 12 , wherein a differential in relative rotational speed of the one or more lower rotating belts and the one or more lower driven delivery feed rollers provides spacing between successive cards as they are delivered to the card collection unit.

15. The apparatus of claim 3 , further comprising:

at least one sensor located in the card collection unit and configured to detect the presence of playing cards in the card collection unit; and

a microprocessor in electrical communication with the at least one sensor and configured to instruct the apparatus to randomly eject playing cards from the initial set of playing cards for delivery into the card collection unit when the sensor indicates an absence of playing cards in the card collection unit.

16. A method of randomly arranging and dealing a plurality of playing cards, the method comprising:

randomly ejecting cards from a stack of a plurality of cards, the ejected cards forming a new staggered stack of a plurality of cards rear of a card separation unit;

limiting a number of ejected cards having access to the card separation unit at any single time by adjusting a card limiting element between the stack of a plurality of cards and a card collection unit;

separating a successive bottom most card from the new staggered stack; and

delivering the separated successive bottom most card to the card collection unit.

17. An apparatus for randomly arranging and dealing a plurality of playing cards, comprising:

a card receiving tray for receiving a stack of cards to be randomized;

a random ejection unit for randomly arranging and ejecting a plurality of playing cards positioned in the tray;

an intermediate card collection area comprising a card support surface and a rotatable stop arm, the stop arm configured to stack ejected cards into a staggered card stack on the card support surface;

an adjustable floating gate that limits a number of cards exiting the intermediate card collection area, the floating gate permitting access to a card separator;

a card separator for receipt of cards from the staggered card stack and for delivery of individual cards to a card collection tray; and

a card collection tray for receiving cards individually delivered from the card separator.

18. The apparatus of claim 17 , wherein the rotatable stop aim comprises a downwardly extending protrusion proximate a front end of the intermediate card collection area.

19. The apparatus of claim 17 , wherein the rotatable stop arm is mounted for rotation about a horizontal axis, and wherein in a first position cards collect beneath the stop ani and in a second position the staggered card stack is formed.

20. The apparatus of claim 17 , further comprising a first card mover for moving cards from the intermediate card collection area to the adjustable floating gate.

21. The apparatus of claim 17 , further comprising a second card mover for moving cards from the adjustable floating gate to the card collection tray.
