Description

  The present invention relates to a gaming machine such as a pachinko machine or a slot machine, and more particularly to a gaming machine provided with fraud prevention means for detecting and preventing fraud.

  Game machines such as pachinko machines and slot machines control game operations by various control boards such as a main control board on which electronic parts such as a CPU and a ROM are mounted and an effect control board. Various control boards are housed in predetermined board cases, sealed, and attached to the gaming machine so that they cannot be seen from the outside.

  In the conventional gaming machine, as a means for sealing the above-mentioned board case and prohibiting the opening and closing of the board case, a sealing sticker (sealing paper) having a paste material applied on the back surface is used, and the seal is sealed by the glue material. Was attached to the opening and closing part of the substrate case. However, since the sealing sticker is only attached to the board case by the adhesive strength of the glue material, the fraudster peels off the sealing sticker without damaging the sealing sticker, opens the board case, and is mounted on the control board. Fraudulent acts, such as replacing the legitimate ROM with illegal ROM, and pasting the peeled seal sticker on the original part of the board case so as not to be understood by others Was a problem.

  In order to detect and prevent such illegal acts more reliably, a device using a chip-shaped electronic component called an IC tag as a sealing seal has been proposed (see Patent Document 1).

  Then, when a fraudster opens a board case in order to illegally remodel the control board or the like, the IC tag disclosed in Patent Document 1 is irreversibly destroyed, and the administrator of the gaming machine or the like is destroyed. By looking at the tag, it is possible to easily detect fraud.

  Next, the structure of the above-described substrate case will be described with reference to FIGS. FIG. 3 is a perspective view showing an appearance of the substrate case in a state where the control board is accommodated and closed, and FIG. 4 is a perspective view showing an opened state of the substrate case. In addition, since the board case for housing the main control board, the board case for housing the production control board, and the board case for housing various other control boards have basically the same structure, The structure of the substrate case 2 that accommodates the control substrate 3 will be described as a representative.

  3 and 4, the substrate case 2 is a box-shaped case formed using a so-called hard plastic material such as a transparent acrylic resin or polycarbonate resin, and has a rectangular shape that accommodates the main control substrate 3. The first case portion 4, the rectangular second case portion 5 that fits over the first case portion 4 so as to be covered from above, and the first case portion 4 and the second case portion 5 are pivotally supported. And a hinge portion 6 that performs. The first case portion 4 is formed with a plurality of fixing portions 7 to be fixed to the back surface of the game board 1h (see FIG. 2) by screws or the like, and the rectangular bottom portion 8 of the first case portion 4 is formed. A mounting portion 9 for mounting and fixing the main control board 3 is integrally formed. The main control board 3 has a wiring pattern formed on the electric circuit board on which an electronic part such as a CPU and ROM, a connector for wiring, a resistor, and a capacitor are mounted on an electric circuit board having insulation. These electronic components are soldered to exhibit a predetermined function.

  Furthermore, a plurality of fitting holes 10 are formed on the side wall (reference numeral omitted) of the first case portion 4, and a plurality of tongue-like fitting projections 11 are formed on the side wall (reference numeral omitted) of the second case portion 5. As shown in FIG. 3, when the second case portion 5 is closed with respect to the first case portion 4, the fitting holes 10 and the fitting protrusions 11 are strongly fitted to each other. The second case parts 4 and 5 are firmly fitted to each other to accommodate the main control board 3.

  Further, as shown in FIG. 4, flat flange portions 12 and 13 are integrally formed on the side wall of the first case portion 4 and the side wall of the second case portion 5, and the flange portion of the second case portion 5 is formed. A microchip MC to be described later is fixed to 13. As shown in FIG. 3, when the second case portion 5 is closed with respect to the first case portion 4, the mutually opposing surfaces of the flange portions 12 and 13 come into contact with each other and are formed on the microchip MC, which will be described later. By adhering the adhesive layer MCe to the surface of the flange portion 12, the flange portions 12 and 13 are fixed to each other.

  Next, with reference to FIGS. 5 and 6, the structure of the microchip MC, the manufacturing method thereof, and the structure of attaching the microchip MC to the flange portion 13 will be described. 5A is an enlarged perspective view showing the structure of the microchip MC, and FIG. 5B is an enlarged perspective view showing the attachment structure of the microchip MC to the flange portion 13.

First, as shown in FIG. 5A, the microchip MC includes a flat transparent substrate MCa formed of polycarbonate resin, a recording layer MCb, a reflective layer MCc, and a protective layer MCd laminated on the transparent substrate MCa. The adhesive layer MCe is included.
Here, the transparent substrate MCa has a thickness of about 0.5 mm and a vertical and horizontal size of about 1 cm, respectively.

  The recording layer MCb is made of an amorphous metal thinly formed on the transparent substrate MCa by a sputtering method. When irradiated with laser light having a predetermined wavelength (in this embodiment, 650 nm), the recording layer MCb is crystallized to non-crystallized or non-crystallized. The state changes from crystallization to crystallization, and recording and erasing of information can be repeated optically by laser light. That is, when the recording layer MCb is irradiated with laser light having a predetermined power modulated based on the information to be recorded, the irradiated portion is crystallized and the reflectance is changed, so that information can be recorded. . In addition, when the crystallized portion is irradiated with a predetermined strong power laser beam and heated and then cooled, the crystalline state can be melted and non-crystallized. Information can be deleted. In this way, the recording layer MCb formed of a thin film of amorphous metal is crystallized and non-crystallized by irradiating laser light, thereby recording and erasing information, and re-recording and re-erasing information. It can be done any number of times. An apparatus for recording and erasing this information will be described later.

  The reflective layer MCc is made of a metal thin film such as gold or aluminum, and is formed as an extremely thin metal thin film by being deposited on the surface of the protective layer MCd having a thickness of about 0.1 mm formed of an ultraviolet curable resin. Yes. Then, the reflective layer MCc and the recording layer MCb are brought into surface contact with each other, and are pressed from both sides of the protective layer MCd and the transparent substrate MCa, so that the reflective layer MCc and the recording layer MCb are mechanically bonded without a gap.

  The adhesive layer MCe is formed of an adhesive such as an acrylic pressure-sensitive adhesive having high peel strength, and is coated on the back surface of the protective layer MCd (the surface opposite to the surface on which the reflective layer MCc is formed). .

  As shown in FIG. 5B, the microchip MC having the structure described above has a rectangular hole 13a formed in the flange portion 13 with the transparent substrate MCa facing upward and the adhesive layer MCe facing downward. It is fitted inside and fixed by an adhesive such as an ultraviolet curable resin or a thermosetting resin filled between the peripheral edge of the transparent substrate MCa and the wall surface of the hole 13a. Further, the adhesive layer MCe and the bottom surface of the flange portion 13 (surface facing the flange portion 12) are flush with each other so that the adhesive layer MCe inserted into the hole 13a does not protrude from the hole 13a. The peripheral edge of the transparent substrate MCa and the hole 13a are fixed by an adhesive such as the above-described ultraviolet curable resin or thermosetting resin.

When the second case portion 5 is closed with respect to the first case portion 4 as shown in FIG. 3, the surfaces of the flange portions 12 and 13 facing each other come into contact as shown in the sectional view of FIG. At the same time, the adhesive layer MCe formed on the microchip MC adheres to the surface of the flange portion 12, the flange portions 12 and 13 are fixed to each other, and the transparent substrate MCa is exposed to the outside.
And the tamper-proof means is realized by the structure of the microchip MC and the flange portions 12 and 13.

  Next, an apparatus for recording and erasing information on the recording layer MCb formed on the microchip MC (hereinafter referred to as “information recording / reproducing apparatus”) will be described with reference to FIG.

  The information recording / reproducing apparatus 100 shown in FIG. 7 has a function of optically reading and reproducing information already recorded on the recording layer MCb, in addition to recording and erasing information on the recording layer MCb. Furthermore, it is formed as a small device that can be operated by a human hand.

The information recording / reproducing apparatus 100 includes a laser diode 101 that emits laser light having a predetermined wavelength (650 nm), a collimating lens 102, and a beam scanning 2 that deflects the collimating lens 102 in a plane orthogonal to the laser light emitting direction. Axis actuator 103, objective lens 104, uniaxial actuator 105 for automatically moving the objective lens 104 forward and backward, and a beam splitter (half mirror) 106 provided between the collimating lens 102 and the objective lens 104 , A condensing lens (collimating lens) 107, and a light receiving element 108 such as a CCD, and further, the laser diode 101, the biaxial actuator 103, the uniaxial actuator 105, and the light receiving element 108 are controlled by a control circuit (not shown). Like To have. Further, the information recording / reproducing apparatus 100 is provided with a liquid crystal display panel so as to display reproduced information described later under the control of the control circuit.
A lens barrel (not shown) in which the objective lens 104 is accommodated is used in proximity to the transparent substrate MCa of the microchip MC.

  When the information recording / reproducing apparatus 100 records information, a laser beam set to a predetermined power for recording information from the laser diode 101 and modulated based on the information to be recorded is emitted. Is done. Further, the laser light is collimated by the collimating lens 102, converged by the objective lens 104 through the beam splitter 106, becomes a fine spot light, and is irradiated onto the recording layer MCb through the transparent substrate MCa. Information recording is performed on the recording layer MCb by the spot light.

  Here, when the spot light is irradiated onto the recording layer MCb, the reflected light reflected from the recording layer MCb enters the light receiving element 108 via the objective lens 104, the beam splitter 106, and the condenser lens 107, and the above-mentioned The control circuit determines the in-focus state of the objective lens 104 based on the light receiving pattern of the reflected light detected by the light receiving element 108 and automatically controls the one-axis actuator 105. By this automatic control, the spot light converged by the objective lens 104 is always focused on the recording layer MCb. Further, the biaxial actuator 103 biases the collimating lens 102 by a predetermined pitch interval, thereby changing the angle of the parallel light described above, and biasing the irradiation position of the spot light on the recording layer MCb. That is, the spot light is biased by the biaxial actuator 103 to scan the recording layer MCb, and information is sequentially recorded on the recording layer MCb.

  Next, when the information recording / reproducing apparatus 100 reproduces information, laser light set to a predetermined power for reproducing information is emitted from the laser diode 101. Further, the laser light is converted into parallel light by the collimator lens 102, is converged by the objective lens 104 through the beam splitter 106, becomes a fine spot light, and is irradiated onto the recording layer MCb through the transparent substrate MCa. Here, similarly to the case of the information recording described above, focusing by the uniaxial actuator 105 and scanning by the biaxial actuator 103 are performed, so that the reflected light including the information stored in the recording layer MCb becomes the objective lens. The light enters the light receiving element 108 via the beam splitter 106 and the condenser lens 107. Then, the control circuit analyzes the light reception pattern of the reflected light detected every moment by the light receiving element 108, reproduces (demodulates) the stored information, and displays it on the liquid crystal display panel.

  Next, when the information recording / reproducing apparatus 100 erases information, a laser beam set to a predetermined power for erasing information is emitted from the laser diode 101. Note that in order to amorphize the information recording portion of the recording layer MCb formed as a thin film of amorphous metal, a high-power laser beam is required. A laser beam having a higher power than that emitted from the laser beam is emitted. Further, as in the case of the information recording described above, focusing by the uniaxial actuator 105 and scanning by the biaxial actuator 103 are performed, so that spot light is recorded on the recording layer MCb via the transparent substrate MCa. Information is erased by irradiating the portion and amorphizing the irradiated portion.

  Next, information recorded on the recording layer MCb of the microchip MC will be described with reference to FIG. 8A is an explanatory diagram showing an enlarged micro bar code recorded on the recording layer MCb of the microchip MC, and FIG. 8B is a visible image recorded on the recording layer MCb of the microchip MC. It is explanatory drawing which shows the case where various information is seen from the transparent substrate MCa side.

  As shown in FIG. 8A, a micro bar code composed of a large number of fine bars is recorded on the recording layer MCb of the microchip MC. The width of each bar is set to about 1 μm, and the minimum distance between adjacent bars is set to about 2 μm. Then, by recording a large number of bars on the recording layer MCb at intervals of an integral multiple of the minimum interval by the laser beam described above, a micro bar code is recorded, and an arrangement of a portion where the bars are recorded and a portion where the bars are not recorded Thus, meaningful information is recorded. For example, the manufacturing number (ID number), the name of the manufacturer, the manufacturing location, the date of manufacture, etc. of each of the gaming machine 1, the board case 2, and the main control board 3 are recorded as a micro bar code. Then, the micro bar code can be read using the information recording / reproducing apparatus 100 described above, and the information of the micro bar code displayed on the liquid crystal display panel provided in the information recording / reproducing apparatus 100 is managed by the gaming machine 1. As a result, the main control board 3 and the board case 2 attached to the gaming machine 1 can determine whether or not unauthorized modification or the like has been performed.

  Furthermore, since the above-mentioned micro barcode is a collection of fine bars, the meaning of information cannot be read even when viewed by humans. Therefore, as shown in FIG. 8B, patterns such as characters, symbols, and figures that can be recognized by human eyes are also recorded on the recording layer MCb of the microchip MC. Here, these patterns are recorded by the information recording / reproducing apparatus 100 described above, and are spot-drawn by spot light applied to the recording layer MCb. In other words, since only a very fine pattern is formed with one spot light, the spot light is scanned two-dimensionally to generate a large number of finely crystallized portions, and point drawing is performed. A pattern of characters, symbols, figures, etc. is recorded on the recording layer MCb by a set of patterns of the portion to be crystallized. In FIG. 8B, as an example, the manufacturing numbers (ID numbers) of the gaming machine 1, the board case 2, and the main control board 3, the name of the manufacturer, the manufacturing location, the manufacturing date, etc. are visually checked. The case where it was recorded in a possible size is shown.

  Then, as shown in FIG. 6, the first and second case portions 4 and 5 are closed, the flange portions 12 and 13 are in contact, and the adhesive layer MCe of the microchip MC is bonded to the flange portion 12. For example, in the case where it is provided in the gaming machine 1, when the fraudster unlocks the gaming machine 1 and forcibly opens the first and second case portions 4 and 5, the cross-sectional view of FIG. As shown, the recording layer MCb and the reflective layer MCc of the microchip MC are peeled off, and the recording layer MCb is damaged. That is, the recording layer MCb and the reflective layer MCc are mechanically pressure-bonded, the protective layer MCd is firmly bonded to the surface of the flange portion 12 by the adhesive layer MCe made of an adhesive, and the transparent substrate MCa is UV-cured. Since it is firmly bonded to the hole 13a of the flange portion 13 by an adhesive such as resin, when the fraudulent person forcibly opens the first and second case portions 4 and 5, the recording layer MCb having the weakest adhesive force The reflective layer MCc is peeled off and damaged.

  When the recording layer MCb and the reflective layer MCc are damaged, the visible patterns such as characters, symbols, and figures illustrated in FIG. 8B recorded on the recording layer MCb are also damaged, and the manager of the gaming machine 1 By seeing the damaged pattern, it can be known that fraud has been made.

  As described above, according to the gaming machine 1 of the present embodiment, the transparent substrate MCa of the microchip MC is fixed to one end (specifically, the flange portion 13) of the second case portion 5, and the first 2 The case part 5 and the first case part 4 in which the main control board 3 is accommodated are closed so that the adhesive MCe formed on the microchip MC is applied to one end of the first case part 4 (specifically, the flange part). The tamper-proof means for prohibiting the opening and closing of the substrate case 2 is configured by bonding to 12). When an unauthorized person opens the substrate case 2 illegally, that is, when the first and second case portions 4 and 5 are opened, the recording layer MCb and the reflective layer MCc formed on the microchip MC are peeled off, and the recording is performed. The layer MCb is damaged. For this reason, the administrator of the gaming machine 1 can easily know that the fraud has been made only by viewing the damaged recording layer MCb through the transparent substrate MCa, and take measures to prevent the fraud. be able to.

  Further, since the microchip MC has a simple structure and can be manufactured regardless of a complicated manufacturing process, the cost can be reduced. For example, although one microchip MC is shown in FIG. 5, an intermediate product in which a recording layer MCb, a reflective layer MCc, a protective layer MCd, and an adhesive layer MCe are laminated on a larger transparent substrate MCa is manufactured. By cutting the intermediate product and mass-producing a large number of microchips MC, it is possible to reduce the manufacturing cost.

  Moreover, when the microchip MC is fixed to one end of the second case portion 5 and the first and second case portions 4 and 5 are closed, the microchip MC is interposed between the first and second case portions 4 and 5. It is possible to realize a structure as a fraud prevention means with the chip MC interposed, and it is possible to improve usability.

  Further, by recording a micro bar code having predetermined information on the recording layer MCb and reading and reproducing the micro bar code by the information recording / reproducing apparatus 100, it is possible to check whether or not an illegal act has been performed.

  Further, since the recording layer MCb formed on the microchip MC can record and erase information, re-record, and re-erase, for example, the administrator of the gaming machine 1 can record the information recording / reproducing device 100. It is possible to take more effective preventive measures against fraud by fraudsters by appropriately updating the information of micro barcodes using, or by appropriately updating patterns of visible characters, symbols, figures, etc. Is possible.

  In the above description, when the microchip MC is fixed to the flange portion 13 of the second substrate case 5 and the first and second substrate cases 4 and 5 are closed, the adhesive formed on the microchip MC. The layer MCe is structured to adhere to the flange portion 12 of the first substrate case 4. However, the microchip MC is fixed to the flange portion 12 of the first substrate case 4, and the first and second substrate cases 4, 4 are attached. When 5 is closed, the adhesive layer MCe formed on the microchip MC may adhere to the flange portion 13 of the second substrate case 5. That is, the first and second substrate cases 4 and 5 are names for convenience, and the first substrate case 4 may be the second substrate case and the second substrate case 5 may be the first substrate case.

  In the above description, the structure of the fraud prevention means provided in the substrate case 2 that accommodates the main control substrate 3 has been described as a representative. However, the substrate case that accommodates the effect control substrate, and various other control substrates. Since the same structure of the anti-fraud means is applied to the substrate case that accommodates the substrate case, it is possible to detect fraud if the substrate case is opened in the same manner as the substrate case 2.

  Moreover, although the embodiment of the pachinko machine has been described, the present invention can be applied to all gaming machines in which various control boards are accommodated in a board case and attached, for example, a slot machine or the like. be able to.
