Abstract

A sensor system for counting cards includes an optical sensor assembly configured to detect edges of cards in a card stack. The optical sensor assembly includes at least an optical sensor, and a light element coupled with the optical sensor. The light element is configured to reflect light from a card stack toward the optical sensor. A remote light element is spaced from the optical sensor assembly. The remote light element is configured to direct light toward the card stack.

First claim

The claimed invention is:

1. A sensor system for counting cards comprising:
an optical sensor assembly configured to detect edges of cards in a card stack, the optical sensor assembly includes:
an optical sensor, and
a reflecting light element coupled with the optical sensor, the reflecting light element configured to reflect light from a card stack toward the optical sensor,

a remote light element spaced from the optical sensor assembly, the remote light element configured to direct light through the card stack and toward the optical sensor; and
wherein one or more of the optical sensor or the remote light element are configured to isolate the optical sensor from uninterrupted light from the remote light element.

2. The sensor system of claim 1 , wherein each of the optical sensor, the light element and the remote light element are oriented orthogonally to faces of the cards in the card stack.

3. The sensor system of claim 1 , wherein the optical sensor is a contact optical sensor configured for contact or placement immediately adjacent to the card stack to detect edges of cards of the card stack.

4. The sensor system of claim 1 comprising a controller in communication with each of the optical sensor assembly and the remote light element.

5. The sensor system of claim 4 , wherein the controller includes:
an initialization module configured to operate the remote light element, and
a translucency comparator configured to compare a light line along the edges of the cards detected by the optical sensor with a translucency threshold.

6. The sensor system of claim 4 , wherein the controller includes:
a light line comparator configured to compare a light line along the edges of the cards detected by the optical sensor with a card detection threshold, and
a counting module configured to count the cards of the card stack according to the comparison of the light line against the card detection threshold.

7. The sensor system of claim 6 comprising a memory in communication with the controller, the memory is configured to store the count of the cards of the card stack.

8. The sensor system of claim 1 comprising an elevator, and each of the optical sensor assembly and the remote light element are coupled with the elevator.

9. The sensor system of claim 1 comprising a hopper magazine including at least two or more hopper bays; and
wherein at least one hopper bay of the two or more hopper bays includes the optical sensor assembly and the remote light element, and another hopper bay of the two or more hopper bays includes another optical sensor assembly and another remote light element.

10. A card storage and dispensing system comprising:
a hopper magazine including two or more hopper bays, each of the two or more hopper bays configured to receive a hopper including cards in a card stack, and each of the two or more hopper bays includes:

an elevator coupled with the card handling mechanism, the elevator is configured to move the card handling mechanism into at least first and second interface positions with the hoppers in the two or more hopper bays.

11. The card storage and dispensing system of claim 10 , wherein the hopper includes an observation orifice and edges of the cards in the card stack are revealed through the observation orifice, and
with the hopper in an installed configuration within one of the two or more hopper bays at least the optical sensor and the light element are directed toward the edges of the cards through the observation orifice.

12. The card storage and dispensing system of claim 10 , wherein the optical sensor and the light element are oriented orthogonally to the faces of the cards in the card stack.

13. The card storage and dispensing system of claim 10 , wherein the optical sensor is a contact optical sensor configured for contact or placement immediately adjacent to the card stack to detect edges of cards of the card stack.

14. The card storage and dispensing system of claim 10 , wherein the elevator is configured to move the card handling mechanism vertically relative to the two or more hopper bays.

15. The sensor system of claim 10 , wherein the elevator is configured to move the card handling mechanism laterally relative to the two or more hopper bays.

16. The sensor system of claim 10 comprising two or more hoppers configured for reception within the respective two or more hopper bays, wherein the two or more hoppers each include a memory device configured to store a count of cards in the respective hopper, the count of cards based on reflected light from the light element detected by the optical sensor.

17. A card hopper comprising:
a hopper housing configured to contain a plurality of cards in a card stack, the hopper includes at least one card slot configured to pass at least one card of the plurality of cards from the card stack; and
