INSPECTION SYSTEM AND GAME TOKEN
An inspection system for inspecting a game token, includes: a game token assigned with code information such that an ID mark region covered with a UV ink is partially irradiated with laser light to denature or remove the irradiated part; an ultraviolet irradiation lamp for irradiating the game token with ultraviolet light for visualizing the UV ink; a UV camera configured to shoot the game token irradiated with ultraviolet light; and an inspection device configured to recognize the code information that has been visualized by the irradiation with ultraviolet light based on an image shot by the UV camera and determine authenticity of the game token.
1 . An inspection system for game tokens for games using a game table, comprising:
a recording device configured to record types and authenticity of the game tokens using a camera; and
an inspection device configured to determine authenticity of the game tokens using a result recorded by the recording device,
wherein each of the game tokens is provided with a unique ID for individual identification in appearance,
the inspection device reads the unique ID of a target game token for inspection among the game tokens using the camera, and determines authenticity of the target game token based on the read unique ID, and
the unique ID for individual identification or for individual identification in a specific group unit is formed by irradiating an ID mark region that is formed of a UV ink or an infrared absorbing material with laser light to partially denature or remove the UV ink or the infrared absorbing material that forms the ID mark region.
2 . The inspection system according to claim 1 , wherein the unique ID is associated with any one of a machine used for manufacturing the game tokens, a sequence of manufacture, time of manufacture, and manufacturing information in a database.
3 . The inspection system according to claim 1 , wherein:
each of the game tokens further includes an RFID or an ID code aside from the unique ID for individual identification that is provided on an outer layer of the game token,
the inspection system further includes a database configured to associate the unique ID provided on the outer layer with the RFID or the ID code, and
the inspection device reads the unique ID added to the target game token for inspection using the camera, and determines authenticity of the target game token based on a result of comparison of the read unique ID and the RFID or the ID code with contents of the database.
4 . The inspection system according to claim 1 , wherein the inspection device is configured to determine authenticity of the game tokens using a normal camera, and an infrared camera or a UV camera.
5 . The inspection system according to claim 1 , wherein the unique ID provided on each of the game tokens is a code expressed by a character or a mark.
6 . The inspection system according to claim 1 , wherein the unique ID provided on each of the game tokens is transparent.
7 . A game token comprising a unique ID for individual identification provided on an outer layer of the game token, wherein:
the unique ID is read by a camera and allows determination of authenticity of the game token, and
the unique ID for individual identification or for individual identification in a specific group unit is formed by irradiating an ID mark region that is formed of a UV ink or an infrared absorbing material with laser light to partially denature or remove the UV ink or the infrared absorbing material that forms the ID mark region.
8 . The game token according to claim 7 , wherein the unique ID is associated with any one of a machine used for manufacturing the game tokens, a sequence of manufacture, time of manufacture, and manufacturing information by a database.
9 . The game token according to claim 7 , further comprising an RFID or an ID code aside from the unique ID for individual identification that is provided on the outer layer of the game token, wherein, by using a database configured to associate the unique ID provided on the outer layer of the game token with the RFID or the ID code, authenticity of the target game token is determined based on a result of comparison of the unique ID assigned to the target game token and the RFID or the ID code with contents of the database.
10 . The game token according to any one of claim 7 , wherein the unique ID provided on the game token is a code expressed by a character or a mark.
11 . The game token according to any one of claim 7 , wherein the unique ID provided on the game token is transparent.
12 . An inspection system for inspecting a game token, comprising:
a game token that includes an ID mark region entirely covered with an ink, and is provided with code information by irradiating a part of the ID mark region with laser light such that the irradiated part is denatured or removed;
a camera for shooting the game token; and
an inspection device configured to read the code information and determine authenticity of the game token based on an image shot by the camera.
13 . The inspection system according to claim 12 , wherein:
the ink that entirely covers the ID mark region is an invisible ink,
the inspection system further includes a lamp configured to irradiate the game token with light for visualizing the invisible ink, and
the inspection device reads the code information that has been visualized by the irradiation with the light.
14 . A game token comprising:
a display surface that displays at least a value of the game token; and
an ID mark region provided on the display surface and entirely covered with an ink,
wherein a part of the ID mark region is irradiated with laser light so that the irradiated part is denatured or removed to add first code information to the game token.
15 . The game token according to claim 14 , wherein:
the ink that entirely covers the ID mark region is a UV ink that emits light when irradiated with ultraviolet light, and
the part irradiated with laser light is denatured or removed so as not to emit light even when irradiated with ultraviolet light.
16 . The game token according to claim 14 , wherein:
the ink that entirely covers the ID mark region is an ink formed of an infrared absorbing material which absorbs infrared rays, and
the part irradiated with laser light is denatured or removed so as not to absorb infrared rays.
17 . The game token according to claim 14 , wherein:
the game token is manufactured by being cut out from a game token original plate,
the game token further includes second code information added with the ink,
the first code information is information that uniquely identifies the game token original plate, and
the second code information is information that specifies a position in the game token original plate.
