Abstract

A device for forming a random set of playing cards is disclosed. The device comprises: a top surface and a bottom surface of the device. A single card receiving area is provided for receiving an initial set of playing cards. A randomizing system for randomizing an order of the initial set of playing cards is provided. A card collection surface in a card collection area for receiving randomized 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 is also provided. An image capture device reads rank and suit of each card before each card is received on the card collection surface. An elevator raises the card collection surface so that at least some randomized cards are elevated at least to the top surface of the device. A processor controls operation of the device. A motor drives the elevator, wherein an encoder is provided for communication with the motor, and wherein the encoder provides a signal indicating that a shuffle has occurred. Embodiments include a processor that creates commands and then receives system signals verifying that the commands were properly executed.

Claims

1. A device for forming a random set of playing cards, the device comprising:

a top surface and a bottom surface;

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

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

a card collection surface in a card collection area of the randomizing system, the card collection

surface configured to receive playing cards one at a time from the card receiving area;

an image capture device configured to read the rank and suit of each card before each card is received on the card collection surface;

an elevator configured to raise the card collection surface so that at least one of the randomized cards is elevated to a position accessible from the top surface of the device;

a processor for controlling operation of the device;

a reading system in information communication with the processor, the reading system configured to determine a number of cards received on the card collection surface from the card receiving area;

a motor for driving the elevator, wherein an encoder is in information communication with the motor, and wherein the encoder is configured to provide a signal indicating a position of the elevator to the processor, wherein the processor is configured to determine that a shuffle has occurred based on data from the reading system.

2. The device of claim 1, wherein the processor is programmed to create commands and to receive system signals verifying that the commands were properly executed.

3. The device of claim 1, wherein the elevator is configured to raise all randomized cards above the top surface of the device and a movable cover is configured to be automatically raised to allow the randomized cards to rise above the top surface of the device.

4. The device of claim 1, further comprising at least one pick-off roller for removing cards one at a time from the card receiving area and moving cards one at a time toward the randomizing system, wherein the image capture device is positioned to read a card only after the card has been moved by the at least one pick-off roller.

5. The device of claim 4, further comprising at least one pair of rollers for receiving each card from the at least one pick-off roller before the image capture device can read each card.

6. The device of claim 5, further comprising a microprocessor for controlling movement of the at least one pick-off roller and the at least one pair of rollers.

7. The device of claim 5, wherein, when a first card being moved by the at least one pick-off roller is being moved by the at least one pair of rollers, movement of the at least one pick-off roller is altered so that no card other than the first card is moved by either the at least one pick-off roller or the at least one pair of rollers.

8. The device of claim 1, wherein the randomizing system is configured to move one card at a time into an area overlying the card collection surface after the one card has been read for suit and rank.

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

10. The device of claim 1, wherein the card collection area is bordered on two opposed sides by movable card gripping elements.

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

12. The device of claim 10, wherein the card collection surface is vertically positionable within the card collection area.

13. The device of claim 12, wherein the elevator is configured to move the card collection surface incremental vertical distances that are less than a thickness of a playing card.

14. The device of claim 13, wherein the elevator comprises a stepper motor or an analog motor.

15. The device of claim 1, wherein a sensor is present along a line of movement of cards in the device within the card receiving area or adjacent the 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.

16. The device of claim 15, further comprising a microprocessor programmed to control vertical movement of the card collection surface and image capture device triggering.

17. The device of claim 1, further comprising a sensor configured to sense the presence of a group of suspended cards.

18. The device of claim 1, further comprising a network connection for communicating shuffle information to a central computer.
