  FIG. 3 is an explanatory diagram showing a configuration of a device for determining the authenticity of the game system according to the first embodiment of the present invention. The device 201 for determining the authenticity of the chip 10 includes the chip 10 used in the game. It is provided on the chip holder 202 that is taken out by the dealer. 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 obtained 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, ROM, and 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 acquiring code information by DNA sequentially or collectively 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 normal chip stored in advance in the control unit 205, and the individual chip 10 is determined depending 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, code information by DNA 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 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.

  The determination of DNA can be performed almost in real time using a device that decodes the returned optoelectronic signal when 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.

  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.
