Abstract

A detection system including a control device detecting fraud performed in a game table by using a result of an image analysis performed by an image analyzing device. A substitute currency for gaming used for this detection system has a multi-layer structure in which a plurality of plastic layers having different colors are stacked, a coloring layer is included at least in the middle, and white layers or thin-color layers (may be layers having a color thinner than that of the coloring layer; not illustrated in the drawing) are stacked on both sides of the coloring layer disposed in the middle.

First claim

The invention claimed is:

1. A substitute currency for gaming, the substitute currency comprising:
a body that enables a type of the substitute currency for gaming to be specified at least by a coloring layer, wherein a striped pattern is formed that includes at least the coloring layer and a white or thin-color layer; and
a print layer representing the type of the substitute currency for gaming coupled to an upper face or a lower face of the substitute currency,
wherein:
a side face of the substitute currency is provided with a side identifier (ID) that allows the substitute currency for gaming to be individually identified,
a radio frequency identifier (RFID) is embedded in the substitute currency, and
the side ID and the RFID are related with each other in a database.

2. The substitute currency according to claim 1 , wherein the side ID is attached to an outer face of the white or thin-color layer.

3. The substitute currency according to claim 2 , wherein one or more side IDs are attached to at least three or more positions spaced apart in a rotation direction of the side face.

4. The substitute currency according to claim 2 , wherein the side ID is printed using ink that is not visible for visible light.

5. The substitute currency according to claim 2 , wherein the side ID is printed using ink configured to absorb infrared rays.

6. The substitute currency according to claim 2 , wherein the side ID is disposed in a plurality of rows on each of outer faces of two layers of the white or thin-color layer.

7. The substitute currency according to claim 1 , wherein round angle processing is performed for outer angles of an upper face or a lower face of the print layer.

8. The substitute currency according to claim 1 , wherein the body includes a metal powder, one or more plastic layers, or a combination thereof.

9. The substitute currency according to claim 8 , wherein the metal powder comprises a metal oxide.

10. The substitute currency according to claim 1 , wherein white layers or thin-color layers are disposed such that the coloring layer interposed therebetween, and thicknesses of upper and lower layers of the at least one of the white layer or the thin-color layer having the coloring layer interposed therebetween are configured to be different from each other.

11. The substitute currency according to claim 1 , wherein the RFID is disposed between at least two plastic layers each forming any one of the coloring layer and the at least one of the white or thin-color layer.

12. The substitute currency according to claim 1 , wherein a face code formed using ultraviolet (UV) emission ink or ink configured to absorb infrared rays is disposed on the print layer.

13. The substitute currency according to claim 1 , wherein:
a face code formed using UV emission ink or ink configured to absorb infrared rays is disposed on the print layer; and
information of the side ID and information of the RFID are associated with each other, the information of the side ID and information of the face code are associated with each other, or the information of the side ID, the information of the RFID, and the information of the face code are associated with each other.

14. An inspection device for inspecting the substitute currency for gaming according to claim 13 , the inspection device comprising:
an RFID reading device configured to read the information of the RFID;
an ID reading device configured to read the side ID disposed on the side face; and
a control device configured to inspect a relation between information acquired by the ID reading device and information acquired by the RFID reading device.

15. An inspection device for inspecting the substitute currency according to claim 13 , the inspection device comprising:
a face code reading device configured to read the face code formed using ultraviolet (UV) emission ink or ink configured to absorb infrared rays disposed on at least one surface of the substitute currency;
an ID reading device configured to read the side ID disposed on the side face; and
a control device configured to inspect a relation between information acquired by the ID reading device and information acquired by the face code reading device.

16. An inspection device for inspecting the substitute currency according to claim 13 , the inspection device comprising:
a face code reading device configured to read the face code formed using UV emission ink or ink configured to absorb infrared rays disposed on at least one surface of the substitute currency;
an ID reading device configured to read the side ID disposed on the side face;
an RFID reading device configured to read the information of the RFID; and
a control device configured to inspect a relation among information acquired by the ID reading device, information acquired by the face code reading device, and information acquired by the RFID reading device.

17. The inspection device according to claim 14 , wherein:
the side ID comprises ink that is visible for visible light, ink configured to absorb infrared rays, or both; and
the ID reading device includes one or a plurality of visible-light cameras or infrared-ray cameras corresponding to the ink of the side ID or a camera capable of performing switching among a plurality of functions of a visible-light camera and an infrared-ray camera corresponding to the ink.

18. The inspection device according to claim 14 , further comprising:
a determination device of a type of the substitute currency that is configured to image the side face of the substitute currency and determine a color of a stripe pattern of the side face of the substitute currency, the side face comprising the coloring layer interposed between the printed layer and the at least one of the white or thin-color layer; and
a print inspecting device configured to:
read print content of the print layer; and
inspect a relation between the type and the print content.

19. A method of manufacturing substitute currency for gaming, the method comprising:
forming a stacked structure body comprising a plurality of plastic layers, the plurality of plastic layers comprising a coloring layer and a white layer or a thin-color layer, each of the coloring layer and white layer or the thin-color layer extend around a side face of the stacked structure body and define at least a portion of the side face;
arranging a print layer in which a drawing pattern is printed on at least an upper face or a lower face of the stacked structure body;
generating a gaming substitute currency original plate by performing thermo-pressing of the plurality of plastic layers and the print layer; and
acquiring a plurality of substitute currencies for gaming having a predetermined shape by performing punching processing of the gaming substitute currency original plate using a mold and performing round angle processing of upper and lower angles of outer sides of the substitute currency using a mold at the time of performing the punching processing.

20. A method of manufacturing substitute currency for gaming, the method comprising:
forming a stacked structure body comprising a plurality of plastic layers, the plurality of plastic layers comprising a coloring layer and a white layer or a thin-color layer, each of the coloring layer and the white layer or the thin-color layer extend around a side face of the stacked structure body and define at least a portion of the side face;
using a layer containing metal powder or a metal oxide inside the layer as at least one
