Definitions

  • the present invention relates, in general, to a casino chip with an antitheft and antiforgery function and a method of manufacturing such chips and, more particularly, to a casino chip, which is provided with an RF tag circuit capable of exposing an offender, by means of an electronic security system consisting of transmitters and receivers, when the offender steals authorized chips from a casino or wrongfully uses forged chips in the casino.
  • a non-contact electronic security system is widely used in various businesses such as stores and libraries, which can expose an offender by using a tag circuit located in wrappers or goods when the offender steals goods from a protected zone.
  • the casino chip is provided with the tag circuit and the electronic security system is set up at entrances for employees, thereby preventing theft of the chip.
  • the forged or imitated chip may be in common use in the casino because the casino chips are valuable. According to the present invention, however, the forged casino chip without the tag circuit or with an unauthorized tag circuit can be readily exposed by the electronic security system comprising a transmitter and a receiver, and which is located in a game table.
  • the casino chip is generally made of plastics. Therefore, when the casino chip is subjected to an injection molding process, the tag circuit in the casino chip may be damaged due to high temperatures, and the tag circuit cannot be positioned in a center of the casino chip due to injection pressure during the traditional injection molding process because the tag circuit is thin and light.
  • the tag circuit is not positioned in the center of the casino chip, it cannot be sensed by the electronic security system.
  • the casino chip manufactured according to a conventional method makes it difficult to variously color the casino chips in order that they may indicate an amount of money, draw lines on a lateral side of the casino chip in order to easily identify the value of a chip when the casino chips are stacked, and draw a special design on a surface of the casino chip.
  • an object of the present invention is to produce a casino chip provided with a tag circuit consisting of an RF IC circuit located on the center of the casino chip, capable of exposing an offender, by means of an electronic security system positioned at entrances of a casino, when the offender steals authorized chips from the casino, thereby effectively preventing theft of the casino chip.
  • Another object of the present invention is to produce a casino chip provided with a tag circuit consisting of an RF IC circuit located at the center of the casino chip which is capable of exposing an offender, by means of an electronic security system located in a game table, when the casino chip not having the tag circuit or the casino chip having an unauthorized tag circuit is used in a casino, thereby forgery and imitation of the casino chip can be effectively prevented.
  • FIG. 1 is a perspective view of a first preform according to the primary embodiment of the present invention
  • FIG. 2 is a perspective view of a second preform according to the primary embodiment of the present invention.
  • FIG. 3 is a sectional view taken in the direction of the arrows substantially along the line A-A of FIG. 1 ;
  • FIG. 4 is a sectional view taken in the direction of the arrows substantially along the line B-B of FIG. 2 ;
  • FIG. 5 is a plan view illustrating an appearance of a tag circuit according to the primary embodiment of the present invention.

  • FIG. 7 is a sectional view of a first preform according to the second embodiment of the present invention.
  • FIG. 8 is a sectional view of a second preform according to the second embodiment of the present invention.
  • FIG. 9 is a plan view illustrating a resulting casino chip according to the second embodiment of the present invention.
  • the present invention provides a casino chip with an antitheft and antiforgery tag circuit, comprising a first preform provided with convex and concave parts formed in a saw tooth shape on the circumferential surface thereof, a position part formed as a groove along the circumferential edge thereof and located at a predetermined distance from the center of a combination side, and a cylindrical concave part located on a back of the combination side; a tag circuit located in the position part of the first preform; a second preform provided with convex and concave parts formed in a saw tooth shape on a circumferential surface thereof and a cylindrical concave part located on a back of a combination side, and combined with the first preform at the combination sides; and a final formed part covering the cylindrical concave part located on each preform.
  • the casino chip further comprises a position part located on the combination side of the second preform.
  • the casino chip further comprises adiabatic members inserted into the position part located between each preform and the tag circuit.
  • a method of manufacturing a casino chip with an antitheft and antiforgery tag circuit comprising the steps of preliminary injection molding preforms so that the preforms are combined with each other to form an integrated body; inserting a tag circuit into a position part located on each preform; combining the preforms having the tag circuits with each other; and insert-injection molding the combined preforms using a mold.
  • the method is characterized in that a plurality of preforms engage with each other in the combining step.
  • a plurality of preforms are welded to each other by an ultrasonic wave in the combining step.
  • the tag circuit is located in the preform and the preform containing the tag circuit is subjected to the insert-injection molding step to produce the casino chip, and so the tag circuit is located at the center of the casino chip and not damaged by high temperatures occurring when the casino chip is being produced.
  • Protrusions 16 are formed on one preform 10 and holes 26 are formed on the other preform 20 so as to assemble the prefoms 10 and 20 with each other at the combination sides of the preforms 10 and 20 , and the number of the protrusions 16 and holes 26 is preferably two or more, respectively, to stably assemble the preforms 10 and 20 with each other.
  • the tag circuit 30 cooperating with a traditional electronic security system is illustrated.
  • the tag circuit 30 is provided with an RF IC circuit 32 , and a plurality of antennas 34 are positioned around the IC circuit 32 .
  • the electronic security system is provided with a transmitter and a receiver, and thus RF (Radio Frequency) is transmitted from the transmitter in the electronic security system to the tag circuit 30 , thereby the casino chip is sensed whether it is authorized or not. Therefore, when employees with the authorized casino chip pass through a doorway with the electronic security system, the casino chip is sensed by the electronic security system. Furthermore, when the unauthorized casino chip is used in the casino, the electronic security system positioned in a game table can sense it.
  • RF Radio Frequency
  • preforms not molded are subjected to an injection molding step using a separate mold to produce preforms 10 and 20 each having a preferred shape.
  • another type casino chip is provided, which has a relatively heavy weight so as to facilitate handling and a high quality appearance.
  • the material of the packing member 60 is selected from the group consisting of high specific gravity plastics (at least 5 to 10 of specific weight), ceramics, glasses, and stone plates.
  • the present invention provides a casino chip with an antitheft and antiforgery tag circuit and a method of manufacturing such chips. Therefore, the theft of an authorized casino chip is prevented because smuggling of an authorized casino chip is easily exposed, and forgery and imitation of the authorized casino chip can be prevented because use of the forged and imitated casino chip is also readily exposed.
  • a tag circuit is not damaged because the tag circuit is protected by a preform even though the preform comprising the tag circuit which is susceptible to high temperatures is subjected to an insert injection molding step, and the casino chip having the tag circuit is readily sensed by an electronic security system because the tag circuit is positioned at the center of the preform.
  • an injection molding step is conducted twice, and so various colors, lines and patterns can be drawn on the surface of the casino chip, thereby casino chips corresponding to various amounts of money can be manufactured.
  • the casino chip is convenient to handle and has a high quality appearance because a heavier material than the main body of the casino chip is inserted into the center of the casino chip.
