Description

  The present invention relates to an anti-counterfeit device, and in particular, a case storing an object targeted for counterfeiting (hereinafter referred to as an anti-counterfeit object), for example, a main board installed for each pachinko machine. The present invention relates to a forgery prevention device for detecting forgery of a forgery object in advance by detecting the opening of a case being opened. The present invention also relates to an anti-counterfeit device that prevents forgery of a forgery object in advance by detecting the opening of the forgery object itself. For convenience of explanation, the present invention will mainly be described in relation to detection of opening of a case containing a counterfeit object, but also includes detection of opening of the counterfeit object itself.

  A simple one for detecting whether or not the case storing the counterfeit object has been opened is a seal. The seal is affixed to an open / close portion of the case that stores the counterfeit object so that the case is broken when the case is opened. For this reason, it is detected that the case has been opened due to breakage of the seal, and it can be seen that the forgery object may have been forged.

Another example of detecting whether a case storing a forged object has been opened is an IC tag disclosed in Japanese Patent Laid-Open No. 2005-107745. This anti-counterfeit IC tag is configured such that the antenna inside the IC tag is damaged when the case is opened at the opening / closing portion of the case containing the forgery object. For this reason, when the antenna is damaged, it becomes impossible to transmit and receive signals between the IC tag and the reading device, and it is detected that the case has been opened, and the forgery object may have been forged. I know that there is.
JP 2005-107745 A

  When using a seal to prevent counterfeiting, it is easy to attach a new seal instead of a damaged seal, that is, it is not sufficient to prevent counterfeiting because the seal can be easily camouflaged. is there. In addition, when using an anti-counterfeit IC tag, in addition to the antenna, a transmitter / receiver, a recording device, and the like are formed in the IC tag, which is expensive.

  Accordingly, an object of the present invention is to provide an anti-counterfeit device that can be manufactured at low cost and can be prevented from being counterfeited so that it cannot be easily counterfeited.

  The present invention relates to an anti-counterfeit device attached to an opening / closing part of a forgery object or an opening / closing part of a case for storing a forgery object, and a part of a chip on which the microcode is recorded is broken when the case is opened. The reproduction is disabled.

  ADVANTAGE OF THE INVENTION According to this invention, the forgery prevention apparatus which can be manufactured cheaply and can prevent forgery is obtained.

  In the forgery prevention device of the present invention, a chip for recording a microcode is attached to an opening / closing part of a case for storing a forgery object. When the case is opened, a part of the chip on which the microcode is recorded is damaged. The microcode cannot be reproduced. When it is detected that the reproduction of the microcode is disabled, the case is opened so that it is possible to recognize that the forgery object may have been forged.

  First, referring to FIG. 1, a case 10 for storing a counterfeit object (not shown) is shown. The case 10 includes, for example, a lower case 12 attached to a pachinko machine (not shown) and an upper case 14 attached to the lower case 12 by a hinge 16 so as to be opened and closed. A through-hole 14 a for inserting and sealing a forgery prevention device (microchip) (hereinafter sometimes referred to as a chip) 20 is formed in an opening / closing portion of the upper case 14. To seal the case 10, the case 10 shown in FIG. 1 a is closed as shown in FIG. 1 b from the opened state, and the chip 20 is inserted into the through hole 14 a as shown in FIG. 1 c. At this time, the chip 20 is bonded to the lower case 12 and the upper case 14 by the adhesive applied to the lower end of the chip, and as a result, the case 10 is sealed by the chip 20. FIG. 1d shows the unsealed state after sealing. At this time, as will be described later, the chip 20 is damaged. In addition, you may attach a chip | tip to the opening-and-closing part of forgery object itself.

  Referring to FIG. 2, a microcode 22 is recorded on the chip 20. The opening / closing part of the case is connected by the main body of the lower case 12 and the main body of the upper case 14 by four ribs 18.

  As shown in FIG. 3a, the chip 20 is formed by sequentially laminating a recording film 20b, a reflective film 20c, a protective film 20d, and an adhesive 20e on the substrate 20a. Here, the substrate 20a is made of any material (for example, a transparent material) that can transmit light used in recording and reproduction. The chip 20 is bonded to the lower case 12 and the upper case 14 by bonding the adhesive 20e to the upper surface of the lower case 12, the inner wall of the through hole 14a of the upper case 14, and the lower surface near the through hole 14a. And when laminating | stacking these films | membranes, the adhesive force weaker than the adhesive force with respect to the lower case 12 of the adhesive agent 20e is provided to at least one location between these films | membranes. For example, in this embodiment, the adhesive force between the recording film 20b and the reflective film 20c is formed to be weaker than the adhesive force of the adhesive 20e to the lower case 12.

  Therefore, as shown in FIG. 3b, when the case 10 is opened, the substrate 20a and the recording film 20b of the chip 20 are bonded to the upper case 14, and the reflective film 20c and the protective film 20d are bonded to the lower case 12. Therefore, the reflective film 20c is peeled off from the recording film 20b. In the state without the reflection film 20c, the amount of reflected light from the reproduction device (or recording / reproduction device) is reduced during reproduction, and the microcode cannot be read and cannot be reproduced. As a result, even if the case is closed again after opening, it is difficult to make the recording film 20b and the reflection film 20c adhere to each other. In addition, the recording film is also distorted or damaged due to peeling, and cannot be reproduced, so that it can be recognized that it has been opened.

  In the above-described embodiment, the adhesive force between the recording film 20b and the reflective film 20c is formed to be weaker than the adhesive force of the adhesive 20e to the lower case 12, but other parts, for example, the substrate 20a You may make it the adhesive force between the recording films 20b become weaker than the adhesive force with respect to the lower case 12 of the adhesive agent 20e. Further, the chip may be configured not to include a reflective film as long as recording and reproduction are possible.

  FIG. 4 shows a microcode used as a code recorded on the recording film 20 b of the chip 20. FIG. 4a shows a micro barcode. FIG. 4b shows a micro two-dimensional code. As is apparent from FIG. 4, the width of the bars is about 1 μm, and the distance between the bars is about 2 μm. The diameter of the chip at this time is about 6 mm, and the thickness is about 1 mm. In order to create such a chip or record a microcode with such a small width on the chip, it is generally necessary to use a chip manufacturing apparatus or a recording (or recording / reproducing) apparatus that is difficult to obtain. Therefore, it is difficult to create and record a chip, which makes it difficult to impersonate. The code may be any appropriate code as long as it is a microcode, and may be a bar code or a QR code, for example. The information recorded as the code is arbitrary and appropriate. For example, in the case of a pachinko machine, there are a pachinko machine number, other manufacturing information, date, place, company name, and the like.

  FIG. 5 shows an example in which the position and direction of the microcode are changed. By changing the position and angle of the microcode for each writing, the difficulty of counterfeiting is increased. For example, information on the positions X, Y and the angle θ from the basic position (center) is added. The basic position is set with reference to the guide portion 19 (see FIG. 2) outside the chip, for example.

  As shown in FIG. 6, the recording / reproducing apparatus 30 includes a laser diode 32, a beam scanning biaxial actuator 34, a collimating lens 36, a biaxial sensor 38, a focusing uniaxial actuator 40, and an objective lens 42. For convenience of illustration, components necessary for reproduction, such as a beam splitter and a light receiving device for separating reflected light from the chip 20, are omitted.

  At the time of recording, light from the laser diode 32 is incident on the objective lens 42 as parallel light by the collimator lens 36, and is focused on the recording film of the chip 20 by the focusing uniaxial actuator 40 and recorded. Here, by moving the beam scanning biaxial actuator 34 within a plane, the angle of the parallel light can be changed and the spot on the recording film can be moved. At this time, the biaxial sensor 38 is for detecting the displacement of the beam scanning biaxial actuator 34. Note that description of reproduction is omitted. The reproduction may use imaging by a camera.

  FIG. 7 shows a chip of another embodiment. As shown in FIG. 7, the chip of this embodiment is a chip in which the recording film and the reflection film are formed in two layers with respect to the chip described in relation to FIG. 3, and an intermediate layer is provided therebetween. That is, the chip 20 includes a substrate 20a, a first recording film 20b1, a first reflective film 20c1, an intermediate layer 20f, a second recording film 20b2, a reflective film 20c2, and a protective film 20d. By configuring the chip in this way, recording and reproduction can be made more difficult, and forgery prevention can be made more reliable.

  The recording may be performed on each of the first recording film 20b1 and the second recording film 20b2, or one of them may be performed. Further, dummy information may be recorded on one recording film. In addition, as a place weaker than the adhesive strength of the adhesive, any appropriate place, for example, between the first recording film 20b1 and the first reflective film 20c1, between the first reflective film 20c1 and the intermediate layer 20f, intermediate Between the layer 20f and the second recording film 20b2, or between the second recording film 20b2 and the second reflective film 20c2, etc. are selected.
