Description

  The present invention has a valuable value such as a pachinko special prize by a three-point method when a customer cashs a prize given to a customer by a pachinko parlor, and is also susceptible to fraudulent acts that are subject to exchange. The present invention relates to a precious metal inclusion body and a method for determining its authenticity.

  Pachinko parlors offer desired prizes according to the number of pachinko balls acquired by customers. However, customers who want to redeem the prize will be given a prize for redemption called “special prize” in the pachinko industry. In this case, the prize is purchased at a prize exchange of another organization, and the prize exchange further sells it to a prize wholesaler of another organization, and the prize wholesaler again wholesales the prize to the pachinko parlor, and the three-point method shown in FIG. 4 is permitted. It is forbidden to sell prizes directly from the prize exchange to the pachinko parlor.

  Conventionally, all of these processes have been performed manually. In this case, it is very inconvenient to handle the gifts of various shapes and sizes such as confectionery and magazines, so a method of simplifying and recycling the gifts to lighter stones, pencils, etc. is used. A noble metal mass inclusion body in which a noble metal mass that is easy to handle is encapsulated is often used. However, manual cash exchange at the prize exchange is complicated and time consuming, is prone to miscalculation, is difficult to manage the flow of prizes, and sometimes illegal, that is, direct transactions between pachinko parlors and prize exchanges, Or, there are many problems that it is easy to cause replacement of counterfeits. Therefore, in order to simplify exchange prizes and prevent replacement of counterfeit goods, methods such as a bar code method, observation with a CCD camera, weight measurement, etc. have been used in the past.

  In order to eliminate imitations as noble metal inclusions used in such cases, techniques such as Patent Document 1 and Patent Document 2 are used.

  That is, in Patent Document 1, a card base having an insertion part on one or both of the front and back surfaces, a frame part provided on at least the periphery of the insertion part on the surface of the card base, and the insertion part A noble metal piece inserted into the card base, a transparent or semi-transparent coating layer laminated on the card substrate, and a part or all of the noble metal piece and at least three sides of the frame portion in a frame shape The precious metal encapsulated card formed from the printed layer formed on the surface of the coating layer so as to remain, and is covered with a transparent or translucent coating layer, so that the precious metal pieces can be visually recognized from the outside. It is said that it cannot be taken out and replaced with poor quality goods.

  Further, in Patent Document 2, identification information is written in a special gift having a control board at a premium wholesaler, and this information is taken to a premium exchange through a pachinko parlor, where the identification information is read, usable information is erased, and a checkout machine. After paying in, you can bring the deleted special prizes to a premium wholesaler, fill in the information that can be used for special prizes, and then deliver it to a pachinko parlor for circulation. It provides a processing method. This makes it possible to prevent unauthorized use of pachinko special prizes in which usable information is not written.

  As examples of printed matter using infrared absorbing ink, inventions such as Patent Documents 3 and 4 are known.

Prior art documents are shown below.
JP 7-246281 A JP-A-5-064861 Japanese Patent Application Laid-Open No. 7-068982 JP 2000-309736 A

  However, for the systems such as Patent Documents 1 and 2, a fraudulent use is made in which a regular product is used as a noble metal enclosure, only the noble metal mass itself is taken out, and the noble metal mass is replaced with a counterfeit. In some cases, fraud could not be dealt with.

  On the other hand, as a method for removing and replacing the noble metal mass itself, there was a method of sticking a seal seal on the lid of the enclosure, but it was not possible to counter the means of taking it out from another place.

  There was also a method of marking with a fluorescent ink on the noble metal mass itself and its foundation, but only visual judgment was possible, and it was possible to visually judge that such an authenticity judgment technique was used, and it was possible to replace only that. It was easy.

  Under such circumstances, it has become necessary to cope with replacement using brass or the like similar to a precious metal lump, for example, similar to gold.

  In order to achieve the above object in the present invention, first, in the invention of claim 1, in the noble metal enclosure in which the noble metal mass is housed in a transparent packaging container, the infrared absorbing ink is printed on the noble metal mass itself. It is an object of the present invention to provide a noble metal enclosure.

  According to a second aspect of the present invention, there is provided a noble metal enclosure according to the first aspect, which further includes a non-contact IC tag capable of outputting value information.

  The invention of claim 3 is characterized in that an infrared light emitting device irradiates the metal enclosure with infrared rays, images the noble metal mass irradiated with infrared rays with an infrared camera, and determines authenticity determination information from the imaging result. The present invention provides a method for determining the authenticity of a precious metal inclusion body.

  According to a fourth aspect of the present invention, there is provided the method for determining the authenticity of a noble metal inclusion body according to the third aspect, wherein the non-contact IC tag communication device receives value information from the non-contact IC tag and makes a value determination. It is to provide.

  Since this invention is the above structure, there exist the following effects.

  Even if fraudulent in which only a noble metal mass itself is taken out and replaced with a counterfeit metal block and imitated, the authenticity of the noble metal mass itself can be determined and fraud is performed. Compared to the case where the fluorescent ink is simply printed on the noble metal block itself, the fact that the measures for authenticity determination have been taken with another new technology (to try fraud) It is not easy for a person to detect) and it is not easy to visually determine the contents of the authentication information.

  For this reason, compared with the conventional authenticity determination measures for the noble metal inclusions, a further anti-fraud (or prevention) effect can be expected.

In addition to the precious metal lump, non-contact IC tags that can output value information are included, so that non-contact IC tags can communicate value information such as their exchange price and number of balls, so that multiple precious metals can be enclosed. Even if there is a body, it becomes possible to process appropriately.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The package enclosing the noble metal mass is provided with a transparent material such that at least the authentication information provided on the surface of the noble metal mass is visible in the infrared and visible with visible light. Therefore, the material is hardened with a transparent resin such as plastic, a container with a shape that cannot be opened, such as a container with a transparent lid, packaging that is shrunk with a film, and other contents cannot be easily removed. Any container may be used as long as it has a possible sealing property and the surface of the noble metal mass as the contents is visible and infrared visible.

  In addition, when there are a plurality of precious metal enclosures to be handled, it is convenient to enclose a non-contact IC medium capable of communicating value information as necessary.

  FIG. 2 is a perspective view of the appearance of a non-contact IC medium according to an embodiment of the present invention. The card-shaped non-contact IC medium 1 includes an IC inlet including a radio frequency IC 21 using a carrier frequency band such as 2.45 GHz and 950 MHz and an antenna 22 having a half-wave dipole antenna shape. Identification information that cannot be rewritten by the user is stored in the IC 21, and the above-described identification information can be read with an external reader by radio communication using the above-described carrier frequency band.

  The identification information in this case may be only value information such as the exchange price and the number of balls, but may include information used for authenticity determination and other information.

  The IC inlet is obtained by forming an etching antenna such as aluminum or copper or a printing antenna using silver paste ink on a substrate such as PET, polyimide, or paper, and mounting the IC 21 on these antennas 22. . The antenna 22 and the IC chip 21 are connected by ACP (different direction conductive paste) / ACF (different direction conductive film) heat and pressure, ultrasonic flip chip mounting, wire bonding, or the like.

  FIG. 4 is a cross-sectional view of the non-contact IC tag 13 and is a diagram for explaining the layer configuration of the non-contact IC tag 13. An IC inlet 4 is embedded between the first base material 8 and the second base material 9 using materials such as vinyl chloride, PET, acrylic, polycarbonate, paper, and the like. All of them are bonded and fixed. As the material of the adhesive layer 7, a resin adhesive such as acrylic or epoxy, hot melt, or the like is used.

  The authenticity determination machine is installed in a place such as a pachinko prize exchange, for example. The details of the procedure for reading the identification information by placing a plurality of precious metal enclosures 1 brought into the pachinko prize exchange on the mounting table of the reader 27 will be described with reference to FIG.

  When a power switch (not shown) is turned on, the sheets are sequentially conveyed from the mounting table of the reader 27 one by one to the inspection area. As shown in FIG. 5, the precious metal enclosure 1 that has reached the inspection area is transformed from the non-contact IC tag operation primary coil 51 to the non-contact IC tag operation secondary coil 52 of the precious metal enclosure 1. The identification information written in the ROM 54 and the EEPROM 55 of the noble metal enclosure 1 is sent from the CPU 56, the reading head 57, and the reading secondary coil 58 to the reading 1 of the reading device 27. It is sent to the reader main body (not shown) through the next coil 51 and the reading interface 59.

  At the same time, the infrared irradiation device is activated to irradiate the area where the authentication information is provided on the surface of the noble metal mass of the noble metal enclosure. At this time, infrared rays are absorbed in a region where infrared absorbing ink is present, but infrared rays are reflected in other regions.

  In this way, an infrared camera is used to simultaneously image an area on the surface of the noble metal mass of the noble metal enclosure where infrared rays are absorbed and reflected, and where the authenticity determination information is provided, and this infrared absorbing ink pattern is read and necessary. The pattern is recognized according to the information and the authentication information is acquired.

  If it is determined that the noble metal block has not been replaced in the authenticity determination as a result, it is determined that the noble metal inclusion body has value information obtained from the non-contact IC medium.

  On the other hand, if it is determined that the noble metal block has been replaced in the authenticity determination as a result, the purchase may not be performed and an alarm may be activated as necessary.

  An embodiment of the present invention will be described below with reference to the drawings.

  As shown in the cross-sectional view of FIG. 1 and the plan view of the upper body with the upper lid removed, the noble metal enclosure has two 5 g gold plates 11 that are plate-shaped gold enclosed in a container, The surface has visible light invisibility that cannot be recognized by human eyes, and the infrared absorbing ink 12 is provided by printing in a pattern of 5 g which is its weight.

A composition comprising 12 parts by weight of p-phenylenediaminium perchlorate (infrared absorbing material) was printed with a film thickness of 2 μm.

  This container is composed of a container body 14 and an upper lid 15, and a gold plate 11 and a non-contact IC tag 13 are fixed to the container body 14, and the surface of the gold plate 11 is directed toward the upper lid 15. ing. The container body 14 is made of ordinary plastic, but the upper lid 15 is made of plastic that is transparent and transmits infrared rays. The upper lid 15 is fitted and fixed to the container body 14.

  As shown in the plan view of FIG. 2, the non-contact IC tag 13 has an IC 22 connected to the antenna 21 sealed with resin, and the IC 22 receives a specific signal of a specific wavelength at the antenna 21. The signal is driven based on the received power of the signal, and the operation is to transmit the value information in the memory through the antenna 21 when the antenna 21 receives a specific signal of a specific wavelength. is there. In the case of the present embodiment, as the value information in the memory, information indicating that two 5 g gold bars are enclosed is used.

  As a specific manufacturing method, the infrared absorbing ink 12 is directly patterned on the gold plate 11 by printing, and the value information is written in the non-contact IC tag 13. Then, the gold plate 11 and the non-contact IC tag 13 are fixed in the container body 14, and finally the upper lid 15 is fitted and bonded and fixed.

  Examples of actual usage will be described below.

  Pachinko players perform pachinko using pachinko cards or pachinko balls purchased with cash. Finally, the pachinko balls obtained from the pachinko are exchanged for the noble metal enclosure 1 of the present invention in accordance with the number of balls at the prize exchange in the store. The same applies when playing with a slot machine or the like.

  The obtained precious metal enclosure 1 is brought into a gift shop outside the pachinko parlor. At the free gift shop, the precious metal enclosure 1 is temporarily stored, and it is applied to the authenticity determination device shown in FIG.

  The authenticity determination device includes a transport device 34 for the noble metal enclosure 1, an infrared irradiation device 35, an infrared imaging device 36, a non-contact IC tag communication device 37, an alarm device (not shown), the infrared imaging device 36 and a non-contact IC tag. It consists of a device 37 and a device authenticity determination system 38 connected to an alarm device.

  The precious metal enclosure 1 received at the gift shop is put into the authenticity determination device, and becomes a precious metal enclosure 31 before inspection. The precious metal inclusion bodies 31 before the inspection are sequentially transported one by one by the transport device 34 and moved to the inspection position. The noble metal enclosure 1 moved to the inspection position becomes a noble metal enclosure 32 under inspection.

  The surface of the noble metal enclosure 32 under inspection is illuminated by the infrared irradiation device 35. The infrared light passes through the upper lid 15 and reaches the surface of the gold plate 11. Here, infrared rays are absorbed in a portion where the infrared absorbing ink 12 is present, and the infrared rays are not reflected. On the other hand, the infrared rays are not reflected in the portion where the infrared absorbing ink 12 is not present, and the infrared rays are reflected. Since the infrared absorbing ink 12 is provided in a pattern of 5 g on the surface of the gold bar 11, the reflected infrared pattern becomes a negative pattern of 5 g after all.

  This infrared reflection pattern is imaged by the infrared imaging device 36, and the imaging result is sent to the authenticity determination device body 38.

  Further, the non-contact IC tag communication device 37 transmits a calling signal on the carrier frequency of the weak radio wave of 2.45 G to the antenna 21 of the non-contact IC tag 13 of the noble metal enclosure 32 under inspection. This is received by the antenna 21, and the response signal in the memory is reversely transmitted by the IC 22 via the antenna 22. The response signal is a response signal placed on the carrier frequency of a weak radio wave of 2.45G, and the meaning thereof is the contents of gold, two pieces, and 5g. The non-contact IC tag communication device 37 that has received the response signal transmits only the received signal to the connected authenticity determination system 38.

  The authenticity determination system 38 processes the received imaging result from the infrared imaging device 35 and the received signal from the non-contact IC tag communication device 37, collates them from both results, and performs authenticity determination. For example, when the authenticity determination information obtained from the captured image is 5 g and the authenticity determination information obtained from the response signal is gold, two, and 5 g, it is determined that the value is equivalent to 10 g of gold, and the transport device 34, the precious metal inclusion body 33 is inspected, and the precious metal inclusion body is purchased at an amount corresponding to the value, and a considerable amount is paid to the player from the prize purchase place.

  Finally, the purchased precious metal inclusion body 1 is sold to a premium wholesaler, and further sold to a pachinko parlor from the premium wholesaler and returned to the store.

  On the other hand, if it is determined that there is no imaging information or a response signal in the authenticity determination device, or if the imaging information and the response signal do not match, it is determined that it is an improper precious metal enclosure, and an alarm device from the authenticity determination device body An alarm signal is output to the alarm device, and the alarm device emits an alarm sound or displays a warning. In this case, it may be configured to automatically report to the police or security company using a reporting system as necessary.
