Abstract

A method includes. determining numbers of a cards sequentially removed from a card shooter and delivered to one or more persons during a round of a card game. The method further includes determining, based on the determined numbers of the cards and based on one or more signals received from a set of card detecting optical sensors of a group of sensors located on one or more card guide rails, whether there is an attempt to draw a card from the card shooter after the round of the card game is over. The method also includes, based a determination of that the attempt occurred, generating a signal indicating the attempt.

Claims (31)

1. A method comprising:

reading, during a round of a card game and using one or more processors, numbers of cards as the cards are sequentially taken out from a card housing and delivered to a player or a banker, a card shooter including the card housing having an opening from which the cards are manually withdrawn from the card housing one by one during the card game;

detecting that one of the cards is located at the opening for longer than a predefined period of time;

outputting a first signal of a result of the detection, wherein the output of the first signal causes a prevention of further delivery of the cards;

determining, using at least one card detecting sensor located on one or more card guide rails, whether there is an attempt to draw a card after the round is over, wherein the attempt to draw the card after the round is over is determined according to the reading of the numbers of the cards as the cards are sequentially taken out from the card shooter and delivered to the player or the banker; and

based on a condition that the attempt to draw the card after the round is over is determined, generating a second signal indicating the attempt to draw the card after the round is over;

wherein:

the at least one card detecting sensor is configured to detect a direction in which any of the cards passes by the at least one card detecting sensor, the second signal being generated based on the detected direction;

the at least one card detecting sensor is arranged below or behind an exterior surface of the card shooter and is configured to detect the cards when the cards are positioned on top or in front of the exterior surface;

the at least one card detecting sensor includes a first object detection sensor and a second object detection sensor that is, with respect to a direction in which the cards are withdrawn from the card shooter, downstream of the first object detection sensor, and the method further comprises using a combination of signals of the first and second object detection sensors to identify a flow of a card relative to the card shooter; and/or

the at least one card detecting sensor includes two optical sensors arranged on opposite sides of a center of a path through which the cards are withdrawn from the card shooter.

2. The method of claim 1 , further comprising storing results of the reading.

3. The method of claim 1 , further comprising tracking progress of the card game based on the numbers of the cards delivered to the player or the banker and based on rules of the card game.

4. The method of claim 1 , further comprising activating, using one or more processors, a card lock based on the first or second signal to restrict further movement of the cards so as to prevent automatic reading of numbers of the cards.

5. The method of claim 1 , further comprising, based on the first or second signal, preventing reading of numbers of the cards.

6. The method of claim 1 , wherein the at least one card detecting sensor includes a first card detecting optical sensor.

7. The method of claim 6 , wherein the at least one card detecting sensor includes a second card detecting optical sensor.

8. The method of claim 1 , further comprising determining a result of a round of the card game.

9. The method of claim 1 , further comprising determining a result of the card game.

10. The method of claim 1 , wherein the at least one card detecting sensor is configured to detect a direction of any of the cards, the first or second signal being generated based on the detected direction.

11. The method of claim 1 , wherein the at least one card detecting sensor is arranged below or behind an exterior surface of the card shooter and is configured to detect the cards when the cards are positioned on top or in front of the exterior surface.

12. The method of claim 1 , wherein the at least one card detecting sensor includes a first object detection sensor and a second object detection sensor that is, with respect to a direction in which the cards are withdrawn from the card shooter, downstream of the first object detection sensor, and the method further comprises using a combination of signals of the first and second object detection sensors to identify a flow of a card relative to the card shooter.

13. The method of claim 12 , wherein the at least one card detecting senor further includes an optical sensor arranged between the first and second object detection sensors.

14. The method of claim 13 , wherein the reading of the numbers is performed by the optical sensor.

15. The method of claim 1 , wherein the at least one card detecting sensor includes two optical sensors arranged on opposite sides of a center of a path through which the cards are withdrawn from the card shooter.

16. The method of claim 1 , further comprising performing a sensing operation using at least one card detecting sensor located on one or more card guide rails, wherein the detecting is performed based on the reading and the sensing operation.

17. The method of claim 1 , wherein:

the at least one card detecting sensor is configured to detect the direction in which any of the cards passes by the at least one card detecting sensor, the second signal being generated based on the detected direction;

the at least one card detecting sensor is arranged below or behind the exterior surface of the card shooter and is configured to detect the cards when the cards are positioned on top or in front of the exterior surface;

the at least one card detecting senor includes the first object detection sensor and the second object detection sensor that is, with respect to the direction in which the cards are withdrawn from the card shooter, downstream of the first object detection sensor, and the method further comprises using the combination of signals of the first and second object detection sensors to identify the flow of the card relative to the card shooter; and

the at least one card detecting sensor includes the two optical sensors arranged on opposite sides of the center of the path through which the cards are withdrawn from the card shooter.
