Abstract
The present invention provides a machine for shuffling multiple decks of playing cards including a first vertically extending magazine for holding a stack of unshuffled playing cards, and second and third vertically extending magazines each for holding a stack of cards, the second and third magazines being horizontally spaced from and adjacent to the first magazine. A first card mover is at the top of the first magazine for moving cards from the top of the stack of cards in the first magazine to the second and third magazines to cut the stack of unshuffled playing cards into two unshuffled stacks. Second and third card movers are at the top of the second and third magazines, respectively, for randomly moving cards from the top of the stack of cards in the second and third magazines, respectively, back to the first magazine, thereby interleaving the cards to form a vertically registered stack of shuffled cards in the first magazine.

6. A method of recovering from a card jam in an automatic card shuffler, comprising:
-
providing an automatic card shuffler with a microprocessor for controlling the operation of the card shuffler;
manually removing cards upon the occurrence of a card jam, wherein after the jam is cleared, the microprocessor causes the shuffler to advance through a complete shuffle cycle after the jam is cleared.

8. An automatic card shuffler comprising:
-
a card moving mechanism;
a multi-segment display device; and
a controller for controlling operation of the shuffler, wherein the controller is in communication with the multi-segment display device, wherein the shuffler displays on the multi-segment display shuffler state information. - View Dependent Claims (9, 10)

-
a card moving mechanism;
a microprocessor for controlling operation of the card shuffler, including the card moving mechanism;
memory;
a program stored in memory for controlling the card moving mechanism;
at least one detector for detecting the presence of a card that is jammed; and

12. A card shuffler comprising:
-
a card moving mechanism;
a microprocessor for controlling operation of the card shuffler, including the card moving mechanism;
memory;
a program stored in memory for controlling the card moving mechanism;
at least one detector for detecting the presence of a card jam; and
a display for displaying the occurrence of a card jam wherein after correction of the jam, the memory provides a program where the shuffler will go through a minimum of one shuffle cycle.

13. A card shuffler comprising:
-
a card moving mechanism;
a microprocessor for controlling operation of the card shuffler, including the card moving mechanism;
memory;
a card receiving area;
a program stored in memory for controlling the card moving mechanism;
at least one detector for physically detecting the presence of a card jam between the card moving mechanism and the card receiving area; and
a multi-segment display for displaying the occurrence of a card jam.

14. An automatic card shuffler comprising:
-
a card moving mechanism that relatively transports cards in a vertical manner relative to card receiving chambers;
a multi-segment display device; and
a controller for controlling operation of the shuffler, wherein the controller is in communication with the multi-segment display device, wherein the shuffler displays on the multi-segment display shuffler state information selected from the group consisting of shuffling counting and card counting.

-
15. A method for shuffling playing cards comprising:
-
loading cards into a shuffling apparatus;
actuating the apparatus to form a group of shuffled cards;
registering use of the apparatus; and
displaying an amount of use registered by the apparatus on a display device. - View Dependent Claims (16)
