It is explanatory drawing which showed the outline | summary of the apparatus which determines this.

The game substitute money (hereinafter referred to as “chip”) is provided with code information encoded by DNA (hereinafter referred to as “code information by DNA”), and the chip 10 has a disk shape. It has an outer shape. The chip 10 includes a body 11 that forms the outer shape of the chip, labels 12 that are attached to both surfaces of the body 11, and a core 13 that is embedded in the body 11. The core 13 includes an RFID tag 131 and a cover sheet 132 that covers the entire RFID tag 131. The body 11 is formed by injection molding using a thermoplastic resin, and is usually colored in a color according to the price of the chip 10 or the like, or a number, a symbol, a pattern, or the like is attached thereto. The body 11 has a concave portion on the main surface, and a label 12 is attached to the concave portion. The label 12 is formed of, for example, a resin film and is used for printing various information.

Here, the configuration of the core 13 will be described. The core 13 includes an RFID tag 131 and a cover sheet 132 that covers the RFID tag 131. The RFID tag 131 has a configuration in which an IC chip 131a and an antenna 131b are disposed on one base film 131c or sandwiched between two base films 131c. Note that the connection mode between the IC chip 131a and the antenna 131b in the RFID tag 131, the pattern shape of the antenna 131b on the base film 131c, and the like are arbitrary, and are not limited to only the mode illustrated in FIG.

Various information can be recorded in the code information by DNA. Particularly important information is coded information for determining the authenticity of the chip 10. Details of the code information by DNA will be described later. As an example of code information by DNA other than coded information for determining authenticity, information indicating the price of the chip 10, information indicating the manufacturer of the chip 10, and the owner of the chip 10 Information representing, information representing the date when the chip 10 was manufactured, information representing the date when the chip 10 was handed over to the owner, information representing a period in which the chip 10 can be used effectively, and effective use of the chip 10 Information that represents the place where it can be considered.

The cover sheet 132 is a flexible sheet that covers the entire RFID tag 131, and as its material, for example, paper, vinyl chloride, polyethylene terephthalate, or the like is preferably used. The cover sheet 132 serves to protect the RFID tag 131 when the body 11 is injection molded. When the RFID tag 131 is sandwiched, the cover sheet 132 runs along the surface of the RFID tag 131 with as little gap as possible and is flexible enough to adhere to the other cover sheet 132 around the RFID tag 131. What is necessary is just to have plasticity. The body 11 is formed by so-called insert molding in which the core 13 is completely embedded in the body 11 by inserting the core 13 into, for example, a mold (not shown) and injecting a thermoplastic resin around the core 13. It is preferable. In the case of insert molding, since a support pin for supporting the core 13 in the mold is required, the shape of the support pin may remain as a through hole in the body 11 after molding. In the drawings attached to the book, illustration of such through holes is omitted.

In the system for determining the authenticity of the game substitute money in the embodiment of the present invention, the game substitute money, that is, the chip 10, mixes the code information by DNA into the thermoplastic resin or the like, and Although the body 11 has a configuration including code information based on DNA, as an application example, the label 12 (plate) attached and fixed to the body may have a configuration including code information based on DNA. It is also possible to realize a configuration in which a seal (not shown) is further attached to the substrate and code information by DNA is given to the attached seal. Furthermore, a structure in which the surface of the body 11 is provided with ink or paint having code information based on DNA may be used.

Specific examples include information representing the price of the chip 10, information representing the manufacturer of the chip 10, information representing the owner of the chip 10, information representing the date on which the chip 10 was manufactured, the chip 10 Information indicating the date when the chip 10 is passed to the owner, information indicating a period during which the chip 10 can be used effectively, information indicating a place where the chip 10 can be used effectively, and the like. Of course, the information recorded on the IC chip 131a is not limited to these specific examples.

FIG. 3 is an explanatory diagram showing the configuration of the device for determining the authenticity of the game system according to the embodiment of the present invention. The device 201 for determining the authenticity of the chip 10 replaces the chip 10 used in the game with a dealer. Is provided on the tip holder 202 that is fed out. The device 201 for determining the authenticity of the chip 10 is configured to acquire code information by DNA of the chip 10 sequentially or at a time from a plurality of chips 10 used in the game. For this reason, the device 201 for determining the authenticity of the chip 10 includes a plurality of light sources and a plurality of DNA sensors 203. As shown in FIG. 3, a transparent bottom plate 204 is provided below a chip holder 202 for holding a plurality of chips 10. Is arranged through. In the case of such a device 201 for determining the authenticity of a chip, even if there are a large number of chips 10 in the chip holder 202, when the chip 10 is provided and accepted for collection or settlement from a game participant, the chip 10 Since the code information by DNA can be acquired sequentially or collectively, the authenticity of the chip 10 can be determined efficiently and immediately. The code information by the DNA of the chip 10 acquired from each chip 10 is compared with the code information by the DNA representing the regular chip stored in advance in the control unit 205, and the authenticity of the chip 10 is determined. As a result of the determination, if an unauthorized chip 10 that is not regular is mixed, the result display unit 206 issues an alarm (buzzer or the like) or displays it with a lamp (not shown).

The control unit 205, which is a DNA determination device, includes an electronic circuit including a microcomputer and a memory, and has a normal computer configuration such as a CPU, a ROM, and a RAM. The control unit 205 including the DNA determination device executes the program stored in the ROM, so that the control of the plurality of light sources and the plurality of DNA sensors 203, the authenticity of the chip 10 and the like are included in the determination and the code information by the DNA Processing related to reading various information is performed.

Next, a method for sequentially or collectively acquiring DNA code information from the chip 10 will be described. The plurality of light sources and the plurality of DNA sensors 203 are further provided with an optical sensor (not shown) such as a CCD for detecting gaps between the plurality of chips 10. This chip 10 is specified, and it is determined whether or not each chip 10 includes code information based on DNA. Further, the detected code information by the unique DNA of the individual chip 10 is stored in the control unit 205. The code information by the unique DNA of the individual chip read and stored is compared with the code information by the DNA representing the regular chip stored in advance in the control unit 205, and the individual chip 10 depends on whether or not they match. The true or false of is determined.

On the other hand, for the chip 10 used in the casino, code information based on DNA as a correct chip set in advance is set. However, in a specific casino, code information based on DNA of the regular chip 10 is set for each casino. Alternatively, code information based on DNA as a regular chip of the chip 10 distributed in units of floors to be used may be registered.

The code information by DNA in the present embodiment is code information by DNA that cannot be read by human vision and can be read under a predetermined condition. The code information based on DNA contains a plurality of types of DNA, and the code information based on DNA may be composed of at least one or a plurality of types of DNA.

Next, DNA code information used in the present invention will be described. The code information by DNA is developed by nanotechnology and molecular science, and has a security function by invisible DNA by combining DNA and forming a sign code or a code. DNA sign code or code code is a complex of chemical substances of about 0.5 to 5 microns in size from a single atom to a polymer, and there are almost infinite types (about 30 trillion or more). Can be produced or reproduced. Also, to prevent forgery and reading, a true sign code can be sneaked into a number of fake codes. From a counterfeiter's point of view, it's almost impossible to duplicate the same thing in the first place, and since it doesn't know what the true sign code is, security is high. Also, since the sign code or encryption code by DNA is transparent and invisible, when it is used even if it is mixed in a transparent liquid or ink, it is usually not known that the DNA itself is mixed. It is very difficult to remove, inactivate, or lose the function of a sign code or the like based on code information of mixed or added DNA.

When a specific light such as UV in a narrow band is applied to a DNA sign code, complex light combining specific wavelengths according to the sign code is returned. The returned light is converted into an electrical signal by an optical sensor (optoelectronic sensor), and the presence or absence of the intended sign code can be determined by decoding the signal. The DNA constituting the sign code or the encryption code can be used by simply mixing a trace amount with other target substances such as pulp, ink, and varnish. Since the substance itself is stable and does not affect the mixed target substance, the normal production process and production speed are not affected by using DNA code information or the like.

DNA can be determined almost in real time using a device that decodes the returned optoelectronic signal when a specific light is applied to an object (actually 0.01 seconds or less). Common holograms are visible, and methods such as using specific metal particles as code information by DNA can be replicated even for invisible types. The conventional method has a weak point compared to the case where it is used.

In this embodiment, a DNA-containing paint and a DNA sensor for detecting it are used. The set information of the DNA-containing paint is an example of set information that cannot be read by human vision and can be read under a predetermined condition. For example, naturally-derived DNA or artificial DNA can be used as the DNA encoding the group information. In addition, a molecular sequence having a periodic sequence, such as a DNA base sequence, can be used to encode set information. For example, the set information may be encoded using the amino acid sequence of the protein. In this case, a molecular arrangement sensor that reads the molecular arrangement of a card (a card having a molecular arrangement in which set information representing a set of cards is encoded) is acquired.

Although various embodiments of the present invention have been described above, the above-described embodiments can of course be modified by those skilled in the art within the scope of the present invention. For example, according to the present invention, it can be used for a game such as blackjack other than baccarat, and the device of the present embodiment may be appropriately modified as necessary in the game to be applied.

Although the presently preferred embodiments of the present invention have been described above, it will be understood that various modifications can be made to the present embodiments and are within the true spirit and scope of the present invention. It is intended that the appended claims include all such variations.
