Abstract

A card shuffling device includes a top surface, a card receiving area for receiving an initial set of playing cards, a randomizing system for randomizing the initial set of playing cards, a collection surface in a card collection area for receiving randomized playing cards, the collection surface receiving cards positioned so that all cards collected are below the top surface of the device, and an elevator for raising the collection surface so that at least some randomized cards are elevated above the top surface of the device. An automatic card shuffler includes a microprocessor with memory, an infeed compartment for receiving cards to be randomized, a card moving mechanism for moving cards individually from the infeed compartment into a card mixing compartment, a card mixing compartment comprising a plurality of substantially vertical supports, an opening for the passage of cards from the infeed compartment, a moveable lower support surface, at least one stationary gripping arm, a lower edge proximate the opening, the gripping arm capable of suspending cards above the opening, and an elevator for raising and lowering the moveable support surface. A position of the elevator is randomly selected and the support surface is moved to the selected position, and after the gripping arm grasps at least one side of the cards, the elevator lowers, creating a space beneath the gripping arm, wherein a card is moved from the infeed compartment into the space, thereby randomizing the cards. A method of randomizing a group of cards utilizing the apparatus is also disclosed.

Claims

1. An automatic card shuffler comprising:

a housing mounted to a gaming table surface such that a card receiver for accepting a group of cards to be shuffled has a support surface that is recessed beneath the top of the gaming table surface when the group of cards is inserted from above the gaming table surface and placed onto the support surface in the card receiver below the gaming table surface;

the card receiver for accepting a group of cards to be shuffled;

a randomizing system for randomizing the order of an initial set of playing cards;

a collection surface for receiving randomized cards;

an elevator for raising the collection surface to an elevation that enables a dealer to manually remove all randomized cards at one time from proximate the gaming table surface; and

a microprocessor for controlling the operation of the card shuffler.

2. The automatic card shuffler of claim 1, and further comprising a movable cover that is closed at least part of the time over at least one of the card receiver and collection surface and is hinged to allow movement.

3. The device of claim 2 further wherein the randomizing system further comprises:

a card randomizing area, the card randomizing area including;

i) a gripping support mechanism for suspending at least one card within the card randomizing area; and

ii) a mechanism for automatically adjusting the gripping support mechanism during operation to suspend cards of varying dimensions.

4. The device of claim 3, wherein the gripping support mechanism comprises a pair of spaced apart gripping pads that move towards the edges of a stack of cards and there is a moveable cover over the card collection area that is hinged to enable movement of the cover.

5. The device of claim 3 further comprising a sensor for sensing the presence of a substack of suspended cards.

6. The device of claim 1 wherein there is a remote controller for controlling the card randomization system by means of a user-manipulated remote control device.

7. The device of claim 6 wherein the remote controller is selected from the group consisting of an infra-red (I.R.) controller and a foot pedal.

8. The device of claim 6 wherein the remote controller comprises an infra-red controller.

9. An automatic card shuffler comprising:

a housing mounted to a gaming table surface such that a card support surface in a card receiver for accepting a group of cards to be shuffled can be recessed at a level beneath the top surface of the gaming table to which the housing is mounted during a shuffling event;

the card receiver for accepting a group of cards to be shuffled;

a randomizing system for randomizing the order of an initial set of playing cards beneath the top surface of the gaming table during the shuffling event;

a collection surface for receiving randomized cards;

an elevator for raising the collection surface to an elevation wherein cards may be removed manually by a dealer from the collection surface;

a moveable cover over the collection surface and hinged to the housing allowing and preventing manual access to the collection surface when the moveable cover is opened and closed, respectively; and

a microprocessor for controlling the operation of the automatic card shuffler.

10. The automatic card shuffler of claim 9 wherein the cover is a flip-up cover.

11. The automatic shuffler of claim 9 wherein the cover is mechanically lifted by the automatic card shuffler.

12. The automatic shuffler of claim 9 wherein the card receiver comprises pick-off rollers.

13. The automatic shuffler of claim 9 wherein the card receiver comprises a sloped surface.

14. The automatic card shuffler of claim 9 wherein the cover moves by rotating about a hinge.
