Abstract

A distinct dealing shoe having no shuffling functionality receives a shuffled, randomized or ordered group of cards. The cards may be mechanically moved one at a time from a receiving area for the deck to a buffer area where more than one card is temporarily stored. The cards in the buffer area are then mechanically moved to a card delivery area where the cards may be manually removed, one at a time, by a dealer. The cards are read one at a time inside of the dealing shoe, either before the buffer area or after leaving the buffer area, but preferably before the cards are being manually removed from a card delivery area. Information from the card reading may be used for game tracking, hand tracking, player information, and other security issues at casino table card games.

Claims

1. A mechanized playing card delivery shoe comprising:

a. A card in-feed area;

b. At least one card mover that mechanically moves cards individually from the card in-feed area to a card delivery area;

c. At least one sensor capable of sensing at least the presence of a card in a card location within the card delivery shoe; and

d. A microprocessor for controlling the operation of the card delivery shoe, wherein the microprocessor receives a signal from the at least one sensor and determines if the signal indicates a jam has occurred, and is programmed to cause the at least one card mover to alter a direction of movement of a card to recover from a jam.

2. The card delivery shoe of claim 1, wherein the at least one card mover comprises at least one pick-off roller.

3. The card delivery shoe of claim 1, wherein the at least one pick-off roller moves cards individually out of the card in-feed area.

4. The card delivery shoe of claim 1, further comprising a card-reading sensor located within the card delivery shoe for sensing card information.

5. The card delivery shoe of claim 4, wherein the information comprises at least one of rank and suit.

6. The card delivery shoe of claim 1, wherein the at least one card mover comprises at least one pair of brake rollers.

7. The card delivery shoe of claim 6, wherein the at least one pair of brake rollers are capable of becoming free-turning while the microprocessor is directing the card delivery shoe to recover from a card jam.

8. The card delivery shoe of claim 1, and further comprising a card path between the card in-feed area and the card delivery area

9. The card delivery shoe of claim 8, wherein the at least one card mover comprises a speed-up rollers located along the card path.

10. The card delivery shoe of claim 8, wherein the at least one sensor comprises multiple sensors located along the card path, and wherein the microprocessor is programmed to initiate an automatic jam recovery routine upon receiving a signal from at least one of the sensors indicating a jam has occurred.

11. The card delivery shoe of claim 10, wherein the jam recovery routine is initiated by either manual or automatic activation.

12. The card delivery shoe of claim 1, wherein the card delivery area comprises a slot adapted for manual removal of individual cards.

13. The card delivery shoe of claim 12, wherein the slot is positioned at an angle with respect to the horizontal, wherein the angle is less than 90 degrees.

14. A method of recovering from a card jam in a card delivery shoe, comprising:

a. Providing a shoe with;

i. a card in-feed area for receiving a group of cards used in a card game;

ii. at least one card moving mechanism that moves cards individually out of the card in-feed area and into a card delivery area;

iii. a card delivery area adapted for manual removal of individual cards;

iv. a drive system for causing the card-moving mechanism to move cards;

v. a sensor capable of sensing a card jam; and

vi. a microprocessor that controls the operation of the shoe;

b. Loading a group of cards into the shoe;

c. Receiving an activation signal to activate the card-moving mechanism to move cards;

d. Moving cards individually from the card in-feed area to the card delivery area; and

e. Wherein the microprocessor causes the drive system to alter normal card movement to automatically recover from a jam when a signal is received from the sensor indicating the occurrence of a jam.

15. The method of claim 14, wherein the group of cards received in the shoe loaded comprises multiple decks of cards.

16. The method of claim 14, wherein the step of moving cards individually comprises moving cards past a card-reading station to determine rank and suit.

17. The method of claim 14, wherein the step of automatically recovering from a jam comprises reversing a direction of movement of a card.

18. The method of claim 17, wherein the step of automatically recovering from a jam comprises resuming a direction of movement of a card after reversing a direction of movement of a card.

19. The method of claim 14, wherein automatically recovering from a jam comprises halting a direction of movement of a card and then resuming the direction of movement of the card.
