Abstract

A multiple mode card shuffling and/or card verification device includes a top surface, a card receiving area for receiving an initial set of playing cards, a randomizing or arranging system for the initial set of playing cards that can be disabled, 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, a card imaging system and an elevator for raising the collection surface so that at least some randomized cards are elevated above the top surface of the device. The processor is programmed such that cards can be verified without changing an order of cards present in the card feeder, verified during randomization, and randomized without card verification.

Claims

1. A multiple mode device that performs at least one operation selected from the group consisting of verifying cards and randomizing an order of cards comprising:

a top surface and a bottom surface of said device;

a single card receiving area for receiving an initial set of playing cards;

a randomizing system comprising components that move for randomizing the order of an initial set of playing cards, wherein only a portion of the components that move in the randomizing system can be and are disabled in a verifying mode;

a collection surface in a card collection area for receiving playing cards one at a time into the card collection area, the collection surface receiving cards so that all cards are received below the top surface of the device;

an image capture device that reads the rank and suit of each card before being received on the card collection surface;

an elevator for raising the collection surface so that all cards are elevated to be manually removed from the top surface of the device;

at least one processor including an associated memory, the associated memory containing a set of expected card values, wherein the at least one processor is configured to perform a) comparing read card values to stored values to verify the cards or b) randomizing an order of cards or c) both verifying the cards and randomizing the cards; and

wherein the processor is further configured to select from among one of the functions a), b) and c); and

wherein a user interface provides a user input that selects among one of the functions a), b) and c).

2. The device of claim 1 wherein during a randomizing mode cards are placed on the elevator in a random order, and further comprising a moveable cover over the elevator.

3. The device of claim 1 wherein at least one pick-off roller removes cards one at a time from the card receiving area and moves cards one at a time towards the elevator and the image capture device can read a card only after it has been moved by the at least one pick-off roller.

4. The device of claim 3 wherein at least one pair of rollers receives each card from the at least one pick-off roller before the image capture device can read each card.

5. The device of claim 4 wherein a microprocessor controls movement of the pick-off roller and the at least one pair of rollers.

6. The device of claim 4 wherein when a first card being moved by the pick-off roller is being moved by the at least one pair of rollers, movement of the pick-off roller is altered so that no card other than the first card is moved by either the pick-off roller or the at least one pair of rollers.

7. The device of claim 1 wherein the randomization system moves one card at a time into an area overlying the collection surface after the one card has been read for suit and rank.

8. The device of claim 1 wherein one card at a time is positioned into a randomized set of playing cards over the collection surface.

9. The device of claim 1 wherein the collection area is bordered by two opposed sides by two opposed movable card gripping elements mounted for horizontal movement are within the collection area, the two gripping elements move horizontally to grip opposed edges of cards at the same time.

10. The device of claim 9 wherein an insertion point to the card collection area is located below a bottom edge of the two movable card gripping elements.

11. The device of claim 9 wherein the card collection surface is vertically positionable within the card collection area.

12. The device of claim 11 wherein the card collection surface is moved by a motivator that is able to move incremental vertical distances that are less than the thickness of a playing card.

13. The device of claim 12 wherein the motor is a stepper motor or an analog motor.

14. The device of claim 1 wherein a sensor is present along a line of movement of cards in the device within the single card receiving area or adjacent the single card receiving area and after the image capture device, the sensor indicating a trigger position of a moving card to initiate a timed capture of an image by the image capture device.

15. The device of claim 14 wherein at least one microprocessor is present in the device and the at least one microprocessor controls vertical movement of the card collection surface and camera triggering.

16. The device of claim 15 wherein the processor is programmed to determine a distance that the card collection surface must be vertically moved to position at least one specific card at a bottom edge of the at least one card gripping element when the card gripping element moves to contact cards within the card collection area.

17. The device of claim 16 wherein the processor is programmed to lower the card collection surface within the card collection area after the at least one element has contacted and supported cards within the card collection area, creating two segments of cards and a gap between the segments.

18. The device of claim 17 wherein the processor directs movement of an individual card into the gap, between the two segments of cards.

19. The device of claim 14 wherein at least a second sensor identifies the position of the card collection surface so as to place a top card in the collection area at a position that is level with or above the bottom of at least one card gripping element that is movable from at least one side of the collection area towards playing cards within the card collection area.

20. The device of claim 19 wherein the at least one card gripping element comprises at least two gripping elements, at least one of which moves from a side of the collection area towards playing cards within the card collection area.

21. The device of claim 1 wherein the processor directs movement of an individual card into a gap in cards in the collection area between two segments of cards created by support of cards by at least one card gripping element.

22. The device of claim 1 wherein the processor is controllably connected to the device, the processor directing movement of playing card moving elements within the device, the processor randomly assigning potential positions for each card within the initial set of playing cards, and then directing the device to arrange the initial set of playing cards into those randomly assigned potential positions to form a randomized final set of playing cards with each card in the randomized set having been read for at least rank.

23. The device of claim 1 wherein a program is embedded in memory in the at least one processor that can be activated to move cards from the card receiving area to the card collection area without randomization, the rank and suit of each card being read between the card receiving area and the card collection area to verify the content of a complete set of cards placed into the card receiving area.

24. The device of claim 1 wherein the processor is programmed to simultaneously perform a function c), wherein the function c) is a combination of functions a) and b) and wherein the input permits the selection of the function c).
