Abstract

Systems and methods for providing ultraviolet (UV) sterilization, disinfection and decontamination of electronic gaming machines (EGMs), gaming chips, dice, playing cards, currency, TITO tickets, etc. The ultraviolet sterilization, disinfection and decontamination may include a singular or plurality of UV lamps of any type or style or UV LEDs or RGB-UV LEDs or any type or style of UV LEDs of at least such wavelengths to be effective in at least partially reducing or eliminating viruses or the like. The UV sources are mounted on, in or proximate to a variety of gaming devices or equipment such as EGMs, mechanical gaming machines, chip trays, chippers, dice holders, automatic card shufflers, bill validators, currency counting devices, currency dispensing devices, printers, magnetic card readers, playing card and currency sterilization, disinfection or decontamination storage mechanisms, ATMs, redemption machines, promotional kiosks, etc., or similar devices used in other industries.

First claim

We claim:

1. A currency receiving and dispensing device comprising:
a currency receiving and dispensing device housing integrated into a gaming machine;
means for receiving and dispensing currency; and
a source of ultraviolet light positioned in, on or proximate to the currency receiving and dispensing device, the source of ultraviolet light configured to transmit ultraviolet light onto individual articles of currency as each article of currency is received during a cash in event and dispensed responsive to a cash out event to at least partially sterilize, disinfect and/or decontaminate at least a portion of the currency as it is being inserted during a cash in event and dispensed during a cash out event.

2. The currency dispensing device of claim 1 wherein the ultraviolet light used to sterilize, disinfect, and/or decontaminate is produced by one or more UV LEDs.

3. The currency dispensing device of claim 1 wherein the ultraviolet light used to sterilize, disinfect, and/or decontaminate is produced by one or more RGB-UV LEDs.

4. The currency dispensing device of claim 1 wherein the ultraviolet light used to sterilize, disinfect, and/or decontaminate is produced by a one or more UV lamps.

5. The currency dispensing device of claim 1 wherein the UV light has at least some UV light with a wavelength in the about 207 nm to 222 nm range.

6. The currency dispensing device of claim 1 wherein the source of ultraviolet light includes reflectors and/or directors to focus ultraviolet light on all or a specific area of the currency.

7. The currency dispensing device of claim 1 including a stack separator mechanism configured to provide UV lighting to sterilize, disinfect and/or decontaminate at least the top of a first stacked article of currency and the bottom of a second stacked article of currency and then move to at least another position to sterilize, disinfect and/or decontaminate at least the top of the second stacked article of currency and the bottom of a third stacked article of currency.

8. The currency dispensing device of claim 1 wherein the effectiveness of the sterilization, disinfection and/or decontamination increases over time of use.

9. The currency dispensing device of claim 1 wherein the effectiveness of the sterilization, disinfection and/or decontamination increases due to the number of repeated exposures to the UV light.

10. A currency receiving and dispensing device comprising:
a currency receiving and dispensing device housing integrated into a gaming machine;
a device configured to received and dispense currency; and
a source of ultraviolet light positioned in, on or proximate to the device configured to receive and dispense currency, the source of ultraviolet light configured to transmit ultraviolet light onto individual articles of currency as each article of currency is received during a cash in event and dispensed responsive to a cash out event to at least partially sterilize, disinfect and/or decontaminate at least a portion of the currency being received during a cash in event and dispensed during a cash out event.

11. The currency dispensing device of claim 10 wherein the ultraviolet light used to sterilize, disinfect, and/or decontaminate is produced by one or more of the following: UV LEDs, RGB-UV LEDs and UV lamps.

12. The currency dispensing device of claim 10 wherein the UV light has at least some UV light with a wavelength in the about 207 nm to 222 nm range.

13. The currency dispensing device of claim 10 wherein the source of ultraviolet light includes reflectors and/or directors to focus ultraviolet light on all or a specific area of the currency.

14. The currency dispensing device of claim 10 including a stack separator mechanism configured to provide UV lighting to sterilize, disinfect and/or decontaminate at least the top of a first stacked article of currency and the bottom of a second stacked article of currency and then move to at least another position to sterilize, disinfect and/or decontaminate at least the top of the second stacked article of currency and the bottom of a third stacked article of currency.

15. The currency dispensing device of claim 10 wherein the effectiveness of the sterilization, disinfection and/or decontamination increases over time of use.

16. The currency dispensing device of claim 10 wherein the effectiveness of the sterilization, disinfection and/or decontamination increases due to the number of repeated exposures to the UV light.

17. A gaming machine comprising:
a device configured to receive and dispense currency, the device configured to receive and dispense currency having a housing, said device integrated into said gaming machine; and
a source of ultraviolet light positioned in, on or proximate to the device configured to receive and dispense currency responsive to a cash out event, the source of ultraviolet light configured to transmit ultraviolet light onto individual articles of currency as each article of currency is received during a cash in event and dispensed to at least partially sterilize, disinfect and/or decontaminate at least a portion of the currency during a cash in event being dispensed during a cash out event.

18. The machine of claim 17 wherein the ultraviolet light used to sterilize, disinfect, and/or decontaminate is produced by one or more of the following: UV LEDs, RGB-UV LEDs and UV lamps.

19. The machine of claim 17 wherein the UV light has at least some UV light with a wavelength in the about 207 nm to 222 nm range.

20. The machine of claim 17 wherein the source of ultraviolet light includes reflectors and/or directors to focus ultraviolet light on all or a specific area of the currency.

21. The machine of claim 17 including a stack separator mechanism configured to provide UV lighting to sterilize, disinfect and/or decontaminate at least the top of a first stacked article of currency and the bottom of a second stacked article of currency and then move to at least another position to sterilize, disinfect and/or decontaminate at least the top of the second stacked article of currency and the bottom of a third stacked article of currency.

22. The machine of claim 17 wherein the effectiveness of the sterilization, disinfection and/or decontamination increases over time of use.

23. The machine of claim 17 wherein the effectiveness of the sterilization, disinfection and/or decontamination increases due to the number of repeated exposures to the UV light.
