Description

  The present invention relates to a fraud countermeasure device for preventing an act of punching a hole from the front surface of a gaming machine and taking out an illegal ball or medal in a gaming machine such as a pachinko machine or a slot machine.

  Along with the development of industrial technology, computerized machines are also becoming computerized, making it possible to control complex games and ornate decorations. However, on the other hand, technology such as cheating and remodeling of gaming machines has also progressed in spite of such technological advancement, and various tricks of so-called “goat acts” have been discovered.

  Effective measures are taken for each company and each method against such various misconducts. Patent Documents 1 and 2 disclose an example of countermeasures against “got action”.

Above all, as one of the tricks of fraud discovered at the recent hall business, drilling holes in the front part of the gaming machine using a soldering machine or electric drill, which is called “drilling goto” There are tricks to get illegal balls and medals by inserting piano wires, wires, celluloid flakes, etc. into the holes. Such a trick must be said to be a bold crime that requires a dedicated tool, but it can be applied to any outer peripheral part such as a decoration part or operation part of a gaming machine. is there. In addition, since there are many gaming machines that do not assume that the outer peripheral portion of the gaming machine is destroyed and foreign objects are inserted therein, an immediate countermeasure against such “drilling goto” is desired.

  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".

  The fraud countermeasure device in the gaming machine of the present invention comprises two electrical wirings arranged in a non-contact manner in the front-rear direction on the front portion of the gaming machine, voltage applying means for applying a voltage between the two electrical wirings, Short circuit monitoring means for monitoring a change of the two electric wirings to a short circuit state. 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, the two electrical wirings are maintained in a non-contact state, so the two electrical wirings do not change to a short-circuited state. . For this reason, the short-circuit monitoring means determines that the gaming machine is maintained in a normal state. On the other hand, when “hole drilling” is performed and a hole is drilled in the front part with a solder iron or electric drill, the two electric wires change to a short-circuited state via the solder metal or the tip metal part of the electric drill. . For this reason, the short circuit monitoring means can determine that an abnormal situation has occurred in the gaming machine.

  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 each of the two electric wirings is composed of a conductive thin plate, a change to a short circuit state can be detected over a wide range.

  Further, the two electric wirings are composed of thin plate-like conductive layers arranged in parallel with each other with a thin plate-like insulating layer interposed therebetween. When an electrode sheet is constituted by the insulating layer and the two conductive layers, a film is formed as an electrode sheet. Since a thin and flexible substrate such as a substrate or a flexible substrate can be used, the degree of freedom of installation location is increased and the installation space can be reduced.

  In addition, when a solder layer is provided on the outer surface of each of the two thin plate-like conductive layers, when the “drilling gore” is performed using a tool whose tip is made of an insulating material, Since the solder melts due to the heat generated by the tip itself and frictional heat between the tips, the tip becomes pierced on the outer periphery, so the solder attached to the tips passes between the two conductive layers. It changes to the short circuit state. For this reason, even when a tool whose tip is made of an insulating material is used, the short-circuit monitoring means can easily determine that an abnormal situation has occurred in the gaming machine.

  Further, when a heat-meltable conductive layer is provided on the outer surface of each of the two thin plate-like conductive layers, the tip portion itself generates heat and the tip portion on the outer periphery of the tip portion of the tool used for “drilling goto”. As the conductive material of the conductive layer melted by the frictional heat between the two adheres, the tip part opens a hole, so that the conductive material attached to the tip part changes the two conductive layers into a short-circuited state. It becomes like this. For this reason, even if it does not provide the above solder layers, the short circuit monitoring means can easily determine that an abnormal situation has occurred in the gaming machine.

  Further, when the short-circuit monitoring means outputs an abnormality detection signal when detecting a change to the short-circuit state of the two electric wirings, it generates sound or light from the gaming machine based on the abnormality detection signal. Abnormalities can be reported to the surroundings, and abnormalities can be known in the hall monitoring room by transmitting an abnormality detection signal to the hall computer.

  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.

  In FIG. 1, the anti-fraud device is a pachinko gaming machine 100 or a slot machine 200, that is, an electrode sheet 1 disposed on the front surface of the gaming machine, as will be described later, in a non-contact state with each other in the longitudinal direction a of the gaming machine. An electrode sheet 1 having two electric wires 11 and 12 to be arranged, a voltage applying means 2 for applying a voltage to the electrode sheet 1, a short-circuit monitoring means 3 for monitoring a change of the electrode sheet 1 to a short-circuit state, When the short circuit monitoring means 3 detects a change of the electrode sheet 1 to the short circuit state and determines that an abnormality has occurred in the gaming machine 100 or 200, a speaker 4 and a lamp that issue an alarm based on an instruction from the short circuit monitoring means 3 5 and a hall computer 6 that receives an abnormality detection signal from the short-circuit monitoring means 3 when the short-circuit monitoring means 3 determines that an abnormality has occurred in the gaming machine 100 or 200. It is prepared for.

  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 fraud countermeasure device is incorporated in the slot machine 200, as shown in FIGS. 8 to 10, the electrode sheet 1 is vertically attached to a light emitting member 203 such as a fluorescent lamp covered with a decorative panel 202 of the front door portion 201. It is disposed on the back surface of the plate 204.

  As shown in FIG. 5, the electrode sheet 1 is formed by sandwiching an insulating layer 13 made of a resin material between two electric wires 11 and 12, and coating the outer surfaces of the electric wires 11 and 12 with an insulating layer 14 and 15 made of a resin material. Configured. Here, the electric wirings 11 and 12 are formed of a thin plate-like conductive layer. In addition, you may make it comprise the electrode sheet 1 by the electrical wiring 11 and 12 which consists of a conductive thin plate, respectively, and the space formed between the two conductive thin plates 11 and 12. FIG.

  Further, as shown in FIG. 7, the electrode sheet 1 may be configured by replacing the insulating layers 14 and 15 shown in FIG. 5 with solder layers or heat-meltable conductive layers 16 and 17.

  Next, processing by the short-circuit monitoring means 3 will be described based on FIG.

  In FIG. 4, the short circuit monitoring means 3 starts the application of the voltage to the electrode sheet 1 by the voltage application means 2 (S1).

  Next, it is determined periodically whether or not an abnormality has occurred in the electrode sheet 1, that is, whether or not the two electrical wirings 11 and 12 of the electrode sheet 1 have changed to a short-circuited state (S2).

  Here, as shown in FIG. 5, the electrical wirings 11 and 12 are in a non-contact state and maintained in an insulating state by the insulating layer 13 in a normal state, but “hole drilling” is performed, as shown in FIG. As described above, when the tip metal portion 300 of the solder iron or the electric drill comes into contact with the two electric wires 11 and 12, the electric wires 11 and 12 are changed to a short-circuited state through the metal portions. In the short circuit monitoring means 3, the change to the short circuit state of the electrode sheet 1 can be detected as a specific voltage or current change.

  Further, when the electrode sheet 1 has the configuration shown in FIG. 7, even if the solder iron or the tip portion 300 of the electric drill does not have conductivity, the tip as shown in FIG. The solder layer or heat-meltable conductive layer 16 melts and adheres to the tip portion 300 due to heat generation or frictional heat of the portion 300 itself, and the two electrical wirings 11 and 12 are short-circuited by the conductive material 16a attached to the tip portion 300. Change to state.

  In step S2, when it is determined that the electrical wirings 11 and 12 are short-circuited and an abnormality has occurred in the electrode sheet 1, a “hole drilling” that damages the electrode sheet 1 from the outside is performed. It is determined that an abnormality has occurred in the machine 100 or 200, and abnormality warning information is output to the hall computer 6 in other words, an abnormality detection signal is output (S3), a warning lamp 5 is lit (S4), and a warning is issued from the speaker 4. A sound is output (S5), and the process ends.

  As described above, the fraud countermeasure device according to the present embodiment has the two electric wires 11 arranged in the front-rear direction of the gaming machine 100 or 200 in a non-contact manner in the front-rear direction (front frame 101 or front door part 201). , 12, a voltage applying means 2 for applying a voltage between the two electric wirings 11, 12, and a short-circuit monitoring means 3 for monitoring a change of the two electric wirings 11, 12 to a short-circuit state, When “goto” is performed and a hole is made in the front surface portion 101 or 201 with a solder iron or an electric drill, the two electric wirings 11 and 12 are brought into a short-circuit state through the tip metal portion 300 of the solder iron or the electric drill. The short circuit monitoring means 3 can determine that an abnormal situation has occurred in the gaming machine 100 or 200 by detecting the change to the short circuit 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.

  Moreover, when the electrode sheet 1 is used, 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, when solder layers or heat-meltable conductive layers 16 and 17 are provided on the outer surfaces of the two thin plate-like conductive layers 11 and 12, the tip portion 300 is formed into a “hole” using a tool made of an insulating material. When "opening goto" is performed, the tip portion 300 has a hole while the conductive material 16a melted by heat generated by the tip portion 300 itself or frictional heat between the tip portion 300 adheres to the outer periphery of the tip portion 300. Since it opens, the conductive material 16a adhering to the tip portion 300 changes between the two conductive layers 11 and 12 into a short circuit state. For this reason, even when a tool made of an insulating material is used for the tip portion 300, the short-circuit monitoring means 3 can easily determine that an abnormal situation has occurred in the gaming machine 100 or 200.

  Further, the short circuit monitoring means 3 outputs an abnormality detection signal when detecting the change of the two electric wirings 11 and 12 to the short circuit state, and therefore, based on this abnormality detection signal, the gaming machine 100 or 200 sends the speaker 4 or By generating sound or light with the lamp 5 and notifying the surroundings of the occurrence of an abnormality, or transmitting an abnormality detection signal to the hall computer 6, the occurrence of the abnormality can be known in the hall monitoring room.

  Here, if an electrical component is not mounted on the electrode sheet 1, the electrode sheet 1 can be used even when the electrode sheet 1 becomes unusable due to the “hole punching” and the electrode sheet 1 needs to be replaced. It is excellent in economic efficiency because it is not necessary to replace the electrical parts.

  In FIG. 11, the anti-fraud device according to the modification includes a PNP transistor 31 in the short-circuit monitoring means 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 one electric wiring 12 of the electrode sheet 1 to which a DC voltage of 5 V is applied at one end is connected to the base. A holding circuit 33 is connected to the collector.

  When the “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 a low level voltage is input to the holding circuit 33. Outputs a signal indicating that the gaming machine 100 or 200 is in a normal state to the input port of the microcomputer 34 based on the low level voltage. On the other hand, when “hole drilling” is performed and the electrical wirings 11 and 12 are short-circuited, a forward voltage is applied between the base and the emitter via the bias resistor 32, and the PNP transistor 31 performs the switching operation to the ON state, A high level voltage is input to the holding circuit 33. When a high level voltage is input, the holding circuit 33 outputs an abnormality occurrence signal indicating that an abnormality has occurred in the gaming machine 100 or 200 to the input port of the microcomputer 34 based on this input voltage, and inputs this abnormality occurrence signal. 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. In FIG. 11, reference numeral 35 denotes a reset circuit for stopping the output of the abnormality occurrence signal from the holding circuit 33 to the microcomputer 34 and resetting the holding circuit 33. The reset circuit 35 is a capacitor 36 when the power is turned on. Until a predetermined voltage is charged, a reset signal is output to the holding circuit 33. A chattering prevention Schmitt trigger circuit 37 and an output inversion Schmitt trigger circuit 38 are connected in series to the output side of the reset circuit 35, and the output side of the output inversion Schmitt trigger circuit 38 is connected to the clear input terminal of the holding circuit 33. ing.
