  The present invention is particularly effective as a countermeasure against “drilling holes” among the frauds as described above, and can easily detect that “drilling holes” have been performed with a simple configuration. It is an object of the present invention to provide a fraud countermeasure device in a gaming machine that can prevent "open goto".

  An anti-fraud device for a gaming machine according to the present invention includes an electrode sheet having one electrical wiring disposed on a front surface portion of the gaming machine, an energization means for passing a weak current through the electrical wiring, and an electrical conduction state of the electrical wiring. And an energization monitoring means for monitoring the change. Here, the front portion is a term for a side surface portion, a back surface portion, an upper surface portion, and a lower surface portion of a gaming machine, and includes a front frame of a pachinko gaming machine and a front door portion of a slot machine.

  In the present invention, when the “hole punching” is not performed on the front portion of the gaming machine, one electrical wiring is maintained in a certain energized state, so that the energization monitoring means keeps the gaming machine in a normal state. Judged to be maintained. On the other hand, when "hole drilling" is performed and a hole is made in the front part with a soldering iron or electric drill, one electrical wiring is short-circuited or disconnected by the solder metal or the tip metal part of the electric drill. As a result, the energized state changes. Therefore, the energization monitoring means can determine that an abnormality has occurred in the gaming machine by detecting the change in the energization state.

  Therefore, according to the present invention, it is possible to easily detect that “hole punching” has been performed with a simple configuration. In addition, it is possible to prevent “hole punching” by knowing that such countermeasures are taken in the gaming machine.

  Here, if the electrical wiring is densely arranged in a single stroke and provided on the electrode sheet, it becomes possible to detect “hole punching” throughout the entire area where the electrical wiring is applied.

  Also, if both sides of the electrode sheet are coated with an insulator, it is possible to make it difficult for Goto to create a short circuit for electrical wiring prior to “drilling goto”.

  Further, if the energization monitoring means outputs an abnormality detection signal when detecting a change in the energization state of the electrical wiring, an abnormality is generated by generating sound or light from the gaming machine based on the abnormality detection signal. By notifying the surroundings or sending an abnormality detection signal to the hall computer, it is possible to know the occurrence of the abnormality in the hall monitoring room.

  Also, if electrical components are not mounted on the electrode sheet, even if the electrode sheet becomes unusable due to the “hole punching” and the electrode sheet needs to be replaced, it is possible to replace only the electrode sheet. This eliminates the need to replace the electrical parts, and is therefore economical.

Each block diagram is shown.

  In FIG. 1, the fraud countermeasure device includes a pachinko gaming machine 100 or a slot machine 200, that is, an electrode sheet 1 having one electrical wiring 11 disposed on the front surface of the gaming machine, and a weakness to the electrode sheet 1. The energization means 2 for energizing the current, the energization monitoring means 3 for monitoring the energization state of the electrode sheet 1, and the energization monitoring means 3 detect a change in the energization state of the electrode sheet 1, and the gaming machine 100 or 200 is abnormal. Hall that receives an abnormality detection signal from the power supply monitoring means 3 when the power generation monitoring means 3 determines that an abnormality has occurred in the gaming machine 100 or 200 as well as the speaker 4 and the lamp 5 that issue an alarm when it is determined that they have occurred. And a computer 6.

  When the fraud countermeasure device is incorporated in the pachinko gaming machine 100, as shown in FIGS. 2 and 3, the electrode sheet 1 is arranged in a region facing the front surface 102a of the rear wall portion of the upper plate 102 on the back surface of the front frame 101. Is done. Further, when the anti-fraud device is incorporated in the slot machine 200, as shown in FIGS. 9 to 11, the electrode sheet 1 is mounted vertically with a light emitting member 203 such as a fluorescent lamp covered with a decorative panel 202 of the front door 201. It is disposed on the back surface of the plate 204.

  The electrode sheet 1 has electrical wirings 11 densely arranged in a single stroke as shown in FIG. 4, 6 or 7, and provided on a plane. Both surfaces of the electrode sheet 1 are as shown in FIG. , Coated with insulators 12 and 13.

  Next, processing by the energization monitoring unit 3 will be described based on FIG. In performing the process shown in FIG. 5, the lamp 5 shown in FIG. 1 includes two types of lamps, a warning lamp 5A and a caution lamp 5B.

  In FIG. 5, the energization monitoring means 3 starts energization of the electrode sheet 1 by the energization means 2 (S1). Next, changes in the amount of current and the amount of voltage in the electrical wiring 11 of the electrode sheet 1 are periodically and repeatedly monitored (S2, S3).

  If it is determined that there is a change in the amount of current or voltage in the electrical wiring 11, it is determined that an abnormality has occurred in the gaming machine 100 or 200 due to an illegal act of deforming or damaging the electrode sheet 1 from the outside. Measurement is started for the time during which the state continues, that is, the abnormal state time (S4).

  When the abnormal state time continues for a predetermined time, for example, 10 seconds or more (S5), the energization monitoring means 3 determines that the “drilling hole” has been performed on the gaming machine 100 or 200, and notifies the hall computer 6 of the abnormal warning information. In other words, an abnormality detection signal is output (S6), the warning lamp 5A is turned on (S7), a warning sound is output from the speaker 4 (S8), and the process ends.

  On the other hand, if the abnormal state time is less than 10 seconds (S5), the energization monitoring means 3 determines that there is a possibility that an abnormality has occurred in the gaming machine 100 or 200. An alert signal is output (S9), the caution lamp 5B is turned on (S10), and the process is terminated.

  As described above, the anti-fraud device according to the present embodiment arranges the electrode sheet 1 having one electrical wiring 11 on the front part (front frame 101 or front door part 201) of the gaming machine 100 or 200, and The power supply means 2 for supplying a weak current to the electric wiring 11 and the power supply monitoring means 3 for monitoring a change in the power supply state of the electric wiring 11 are provided.

  When the “hole punching” is not performed on the front surface portion 101 or 201 of the gaming machine 100 or 200, one electrical wiring 11 is maintained in a constant energized state. 100 or 200 is determined to be maintained in a normal state. On the other hand, when “hole drilling” is performed and a hole is made in the front surface portion 101 or 201 with a solder iron or electric drill, one electric wiring 11 is short-circuited in the middle by the solder metal or the tip metal part of the electric drill. Or disconnection causes a change in the energized state. Therefore, the energization monitoring unit 3 can detect that an abnormality has occurred in the gaming machine by detecting the change in the energized state.

  Therefore, according to the present embodiment, it is possible to easily detect that the “hole punching” has been performed with a simple configuration. In addition, it is known that such a countermeasure is applied to the gaming machine 100 or 200, so that it is possible to prevent the “drilling hole” from occurring.

  The electrical wiring 11 is provided in the electrode sheet 1 densely in a single stroke. For this reason, it becomes possible to detect “hole punching” over the entire region where the electrical wiring 11 is applied. Moreover, since the electrode sheet 1 is thin and flexible, it has high versatility and can be attached to any part. In the embodiment described above, the electrode sheet 1 includes the area facing the front surface 102a of the rear wall portion of the upper plate 102 on the back surface of the front frame 101 of the pachinko gaming machine 100, and the decorative panel of the front door portion 201 of the slot machine 200. A light emitting member 203 such as a fluorescent lamp covered with 202 is disposed on the back surface of the vertical mounting plate 204. In the vicinity of the back surface of the upper plate 102 of the pachinko gaming machine 100, not only are the parts directly related to the gaming machine 100, such as a prize ball payout exit and a launch rail, but also adjacent to the upper plate 102. Since the gaming area exists, this embodiment is a means to counter the trick such as opening a hole in the upper plate 102 and inserting a piece of wire, piano wire, celluloid, etc. It is valid. In many of the slot machines 200, a coin payout device called a hopper is disposed near the back surface of the front decorative panel 202. A foreign object is inserted into the hopper from the outside to cause a malfunction. There are some tricks to get coins illegally. In the case of such a technique, it is not sufficient to prevent the insertion of foreign matter from the gap of the slot machine 200 as in the conventional case, and a case where a foreign object is inserted through a hole in the slot machine 200 itself. Therefore, the present embodiment is effective as a countermeasure. Further, both the pachinko gaming machine 100 and the slot machine 200 have a technique for illegally obtaining game media by erroneously operating an operation unit such as a prepaid card or an electronic game media counting means called a so-called credit means. Therefore, it is also effective to dispose the present embodiment in the vicinity of the game medium counting means.

  Further, both surfaces of the electrode sheet 1 are coated with insulators 12 and 13. For this reason, even if it is going to form a new short circuit with the copper wire, metal, etc. on the surface of this electrode sheet 1, not only the operation | work which peels a coating layer is difficult, but the electrode sheet 1 is comprised by the thin plate shape. Therefore, there is a high possibility that the electrode sheet itself is torn during the work and the circuit is cut. That is, by coating both surfaces of the electrode sheet 1 with an insulator, the detection rate of fraud is increased.

  Further, the energization monitoring means 3 outputs an abnormality detection signal when detecting a change in the energization state of the electrical wiring 11, so that sound or light is output from the gaming machine 100 or 200 by the speaker 4 or lamp 5 based on the abnormality detection signal. The occurrence of abnormality can be notified to the surroundings. Further, by transmitting an abnormality detection signal to the hall computer 6, it is possible to know the occurrence of an abnormality in the hall monitoring room.

  Further, if electrical components are not mounted on the electrode sheet 1, only the electrode sheet 1 can be used even if the electrode sheet 1 becomes unusable due to a “hole punching” and the electrode sheet 1 needs to be replaced. Since it is only necessary to replace the electric parts, it is not necessary to replace the electric parts.

  In FIG. 12, the anti-fraud device according to the modification includes a PNP transistor 31 as the energization monitoring unit 3. A DC voltage of 5 V is applied to the emitter of the PNP transistor 31. A bias resistor 32 is connected between the base and the emitter. The other end of the electric wiring 11 of the electrode sheet 1 to which a DC voltage of 5 V is applied at one end is connected to the base. A light emitting diode as the lamp 5 is connected to the collector.

  When “hole punching” is not performed on the front surface portion 101 or 201 of the gaming machine 100 or 200, the PNP transistor 31 is maintained in the off state, and no current flows through the light emitting diode 5, so that the light emitting diode 5 Does not emit light. On the other hand, when “hole drilling” is performed and the electric wiring 11 is disconnected, the base current flows through the bias resistor 32, the PNP transistor 31 performs the switching operation to the OFF state, and the current flows through the light emitting diode 5 to emit light. The diode 5 emits light. By the light emission of the light emitting diode 5, it is possible to inform the surroundings that the “hole punching” has been performed.

  In FIG. 13, the anti-fraud device according to another modification includes an NPN transistor 33 and a microcomputer 34 as the energization monitoring unit 3. A 5 V DC voltage is applied to the collector of the NPN transistor 33, and the collector is connected to the input port of the microcomputer 34. A bias resistor 35 is connected between the base and the emitter. The other end of the electric wiring 11 of the electrode sheet 1 to which a DC voltage of 5 V is applied at one end is connected to the base.

  When the front hole 101 or 201 of the gaming machine 100 or 200 is not “drilled”, a current flows through the bias resistor 25, the NPN transistor 33 is kept on, and the microcomputer 34 is connected to the input port. Is inputted with a low level voltage. On the other hand, when “hole drilling” is performed and the electric wiring 11 is disconnected, no current flows through the bias resistor 35, and the NPN transistor 33 performs a switching operation to an off state. For this reason, the input voltage of the input port of the microcomputer 34 is inverted to a high level. When the input voltage at the input port is inverted to a high level, the microcomputer 34 outputs an abnormality detection signal from the output port to the speaker 4, the lamp 5, and the hall computer 6 shown in FIG. 1.

  The fraud countermeasure devices shown in FIGS. 12 and 13 can also easily detect that the “drilling hole” has been performed with a simple configuration.
