Description

  The present invention relates to an abnormality detection device, a gaming machine, an abnormality detection method, and an abnormality detection program used in a game hall or the like.

  In a game arcade where a gaming machine such as a pachinko gaming machine or a slot gaming machine is installed, there is no end to illegal acts in which the gaming machine is illegally modified so that a player can illegally acquire gaming media. Specifically, this fraudulent act is performed by exchanging the main control board that controls the gaming machine or the ROM mounted on the main control board with an illegal one (so-called back ROM).

  And the damage which a game hall suffers by such a fraudulent act is enormous. Conventionally, various anti-fraud measures have been taken at each game hall in order to prevent fraud. For example, in each amusement hall, measures are taken such as installing a surveillance camera or increasing the number of employees in order to monitor fraud.

  As another countermeasure against fraud, an IC tag having identification information is attached to the board case of the main control board of the gaming machine, and the IC tag is read by a tag reader attached to the inside of the game island.

(Example of main control board configuration)
Next, an example of the configuration of the main control board according to the first embodiment will be described with reference to FIG. FIG. 4 is an explanatory diagram of an example of the configuration of the main control board according to the first embodiment.

  In FIG. 4, the main control board 400 has electronic parts 402 such as a CPU, ROM, and RAM mounted on a board body 401. Further, an LED 403 serving as a light emitting unit is provided at the center on the substrate body 401, and the LED 403 emits visible light having a predetermined intensity. In the first embodiment, an LED (light emitting diode) is used as the light emitting unit, but an inverter type fluorescent lamp, a direct current type fluorescent lamp, or the like can also be used.

  Any LED 403 may be used as long as it emits visible light that can be received by the hall computer 120. Note that the visible light emitted from the LED 403 may include identification information unique to the gaming machine. In this case, it is also possible to determine whether or not the main control board 400 has been illegally replaced by performing a match determination as to whether or not the identification information is information associated with the gaming machine 110 in advance. It is.

  Thus, when identification information is included in visible light, for example, it is modulated by a modulation method such as subcarrier inversion pulse phase modulation for transferring data by blinking the light source at high speed once at regular intervals. Radiate light. Note that the LED 403 blinks at high speed, but is visually lit, and thus also plays a role in illuminating the interior of a dim island facility.

  The visible light emitted from the LED 403 is received by the light receiving sensor 122 (see FIG. 1) disposed on the ceiling or the like in the game hall A as described above. Therefore, it is desirable that there is no shielding object that blocks visible light between the LED 403 and the light receiving sensor 122. In order to prevent the visible light from being blocked by the top board of the game island, for example, the top board may be made transparent or an opening for guiding visible light from the top board may be provided. Good.

  Further, when the main control board 400 is inward, for example, when the back cover 320 (see FIG. 3) is configured to block visible light, a light guide means such as a mirror or a lens is used. Also good. In addition, although the LED 403 is always on, the LED 403 may be turned on only during business hours or during non-business hours, or may be turned on at a predetermined timing such as every other hour. . The hall computer 120 may be turned on only when receiving visible light from the LED 403.

  In the first embodiment, the light receiving sensor 122 is provided on the ceiling of the game arcade A, but is not limited thereto, and may be provided, for example, in a game island. Further, the number of the light receiving sensors 122 is not particularly limited as long as the LED 403 of each gaming machine 110 can be received. For example, the number of the light receiving sensors 122 may be one for each gaming island, or one for each gaming machine 110. The number may be one, or one for every predetermined number of gaming machines 110.

  The main control board 400 is accommodated in the board case 310. The substrate case 310 has a rectangular shape and is configured by an upper surface portion 410 that covers the upper surface of the main control substrate 400 on which the electronic component 402 that controls the gaming machine 110 is mounted, and a side wall 411 that covers the side surfaces.

  The upper surface portion 410 of the substrate case 310 is configured by a surface substantially parallel to the substrate body 401 installed inside the substrate case 310. On the other hand, the side wall 411 is configured by a surface substantially perpendicular to the substrate body 401. Therefore, the substrate case 310 and the main control substrate 400 form a rectangular parallelepiped. Since the substrate case 310 is made of a transparent member such as acrylic, the inside can be visually observed from the outside, and it is possible to confirm whether or not the main control substrate 400 has been illegally replaced. .

(Functional configuration of fraud monitoring system 100)
Next, a functional configuration of the fraud monitoring system 100 according to the first embodiment will be described with reference to FIG. FIG. 5 is a block diagram of a functional configuration of the fraud monitoring system 100 according to the first embodiment. In FIG. 5, the fraud monitoring system 100 includes a gaming machine 110, a hall computer 120, and a monitoring server 130.

  The gaming machine 110 includes a light emitting unit 501. The light emitting unit 501 corresponds to the LED 403 illustrated in FIG. 4 and transmits visible light having a predetermined intensity that can be received by the hall computer 120. That is, the light emitted from the light emitting unit 501 (LED 403) is visible.

  The hall computer 120 includes a registration unit 521, a reception unit 522, a determination unit 523, an output unit 524, a display unit 525, a transmission unit 526, and a registration control unit 527. The hall computer 120 is connected to the light receiving unit 510 (corresponding to the light receiving sensor 122) by wire or wirelessly. The light receiving unit 510 receives visible light transmitted from the light emitting unit 501 of the gaming machine 110. The received light is sent to the hall computer 120 as an electrical signal.

  In FIG. 5, a region 550 indicated by a dotted line indicates the abnormality detection device according to the present invention. That is, the abnormality detection device includes the hall computer 120 and the light receiving unit 510.

  The registration unit 521 registers in advance the reception intensity of visible light transmitted from the light emitting unit 501 as the set reception intensity for each gaming machine 110. More specifically, the set reception strength is the initial value at the start of use. The reception intensity is specifically the illuminance on the light receiving unit 510 side.

  The receiving unit 522 receives the visible light transmitted from the light emitting unit 501 via the light receiving unit 510. Specifically, the receiving unit 522 receives the electrical signal sent from the light receiving unit 510. Reception from the light receiving unit 510 by the receiving unit 522 is performed during a monitoring mode such as a predetermined time such as during business hours or non-business hours or a predetermined interval such as every other hour. Good.

  The determination unit 523 determines whether or not the intensity of visible light received by the reception unit 522 is within a predetermined range with respect to the set reception intensity registered in the registration unit 521. The intensity of visible light includes, for example, a decrease in output due to a distance between the light emitting unit 501 and the light receiving unit 510 that changes with an opening / closing operation with respect to the installation frame of the gaming machine 110, a time-dependent use of the light emitting unit 501, etc. Some errors occur each time due to a decrease in sensitivity due to the use of the portion 510 over time. The predetermined range is a range in consideration of the error.

  The output unit 524 outputs abnormality information indicating an abnormality of the gaming machine 110 when the determination unit 523 determines that the intensity of visible light is not within the predetermined range. The output format by the output unit 524 is display by the display unit 525 or transmission to the monitoring server 130 using the transmission unit 526. In addition to this, audio output such as alarm sound, print output by an external printer, memory Data output (save) or the like may be used.

  In addition, when the determination unit 523 determines that the visible light intensity is within the predetermined range, the registration control unit 527 sets the visible light intensity received by the reception unit 522 to the registration unit 521 as the set reception intensity. Let me register. That is, the determination unit 523 determines whether the intensity of visible light received next time is within a predetermined range based on the intensity of visible light received before the previous time.

  Note that with such a configuration, for example, when the reception intensity becomes a value just below the lower limit every time due to, for example, a decrease in the output of the light emitting unit 501 or a decrease in the sensitivity of the light receiving unit 510, the set reception intensity gradually decreases. Furthermore, it is assumed that the set reception intensity becomes extremely low, for example, even if it corresponds to a failure of the light emitting unit 501 and is determined to be appropriate. In order to cope with such a situation, when the set reception intensity falls below a predetermined value, a function for notifying a malfunction or failure of the machine may be provided.

  In addition, the registration control unit 527 calculates a predetermined average value using the intensity of visible light received by the reception unit 522 and causes the registration unit 521 to register the calculated average value as the set reception intensity. The predetermined average value to be calculated is an average value for a predetermined number of times or an average value for a predetermined period. That is, the predetermined average value may be, for example, the average value for the past five times, or the average value for the last three days.

  In addition, the output unit 524 outputs abnormality information including time information for specifying the time when an abnormality has occurred in the gaming machine 110 or game machine information for specifying the gaming machine in which the abnormality has occurred.

  The transmission unit 526 transmits the above-described abnormality information to the monitoring server 130 that monitors fraud related to the game hall A. Further, the transmission unit 526 transmits abnormality information including game hall information such as a game hall ID for identifying the game hall A where the gaming machine 110 in which the abnormality has occurred is installed to the monitoring server 130.

Note that the reception unit 522 and the transmission unit 526 illustrated in FIG. 5 are realized by the communication I / F 613.

(Registration information recorded on the magnetic disk)
Next, the contents of the registration information recorded on the magnetic disk 605 shown in FIG. 6 will be described with reference to FIG. FIG. 7 is an explanatory diagram showing the contents of registration information recorded on the magnetic disk 605. In FIG. 7, the magnetic disk 605 holds registration information 700-1 to 700-n including a gaming machine number and a set reception strength for each of the gaming machines 110-1 to 110-n installed in the game hall A. ing. The registration information may include a gaming machine ID, model information, manufacturer information, and the like.

  The gaming machine number is information for distinguishing each gaming machine 110-1 to 110-n, for example, information for specifying the position of each gaming machine 110-1 to 110-n in the game hall A. It is. The set reception intensity indicates an allowable intensity of visible light received from the LEDs 403 of the gaming machines 110-1 to 110-n.

  Here, taking the gaming machine 110-2 as an example, the registration information 700-2 has a gaming machine number “A002” and a set reception strength “× ˜ □”. That is, the information for specifying the position of the gaming machine 110-2 in the game hall A is “A002”, and the allowable reception strength is “× ˜ □”.

  Note that the validity determination by the CPU 601 shown in FIG. 6 will be supplemented with a specific example. For example, when the gaming machine 110-2 installed in the game hall A is taken as an example, when the reception intensity of visible light received from the LED 403 of the gaming machine 110-2 is within “× ˜ □”. Then, it is determined that the main control board 400 has not been illegally replaced. On the other hand, when the reception intensity is not within “× ˜ □”, it is determined that there is a possibility that the main control board 400 has been illegally replaced.

(Illegal monitoring system monitoring procedure)
Next, a monitoring process procedure of the fraud monitoring system 100 according to the first embodiment will be described. FIG. 8A is a sequence diagram of the monitoring process procedure of the fraud monitoring system 100 according to the first embodiment. In FIG. 8A, first, the gaming machine 110 always emits visible light including identification information unique to the gaming machine using the LED 403 (step S801). Note that the LED 403 continues to be lit until, for example, a predetermined switch dedicated to the LED 403 is turned off, is turned off when the switch is turned off, and the processing in the gaming machine 110 is terminated with the turning off.

  Then, the hall computer 120 determines whether or not it is in the monitoring mode (step S802). It is in a standby state until it enters the monitoring mode (step S802: No loop), and when it is in the monitoring mode (step S802: Yes), it receives light emission of the LED 403 from the gaming machine 110 and communicates via the light receiving sensor 122. Visible light is received by the I / F 613 (step S803). Then, the reception intensity is measured (step S804).

  Note that, for example, when a store clerk checks the gaming machine 110, when the gaming machine 110 is released from the installation frame, it is assumed that light reception by the light receiving sensor 122 is temporarily disabled. Considering such a case, for example, when the gaming machine 110 is unlocked with respect to the installation frame, the determination as to whether or not the gaming machine 110 can receive light is invalidated. Yes.

  Thereafter, using the set reception strength, it is determined whether the reception strength is within a predetermined range (step S805). When it is determined that the reception intensity is within the predetermined range (step S805: Yes), the process returns to step S803. On the other hand, when it is determined that the received intensity is not within the predetermined range (step S805: No), the abnormality information is displayed and output from the display 612 (step S806).

  8-2, the hall computer 120 determines whether or not the received intensity of visible light received from the LED 403 is within a predetermined range (step S821). Note that the determination in step S821 is the same as the determination in step S805 of FIG. If it is determined in step S821 that the reception intensity is within the predetermined range (step S821: Yes), the visible light reception in step S803 in FIG. An average value is calculated for (step S822).

  Then, the calculated average value is recorded on the magnetic disk 605 as the set reception intensity (step S823), and the series of processes is terminated. If it is determined in step S821 that the received intensity is not within the predetermined range (step S821: No), the processing below the abnormal information output in step S806 in FIG. The process ends.

(Embodiment 2)
(Example of configuration of main control board using black light)
Next, an example of the configuration of the main control board according to the second embodiment will be described with reference to FIGS. 10 and 11. FIG. 10 is an explanatory diagram of an example of the configuration of the main control board using the black light according to the second embodiment. FIG. 11 is a cross-sectional view showing the AA cross section of FIG. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  In FIG. 10, the main control board 1000 has electronic parts 402 such as a CPU, a ROM, and a RAM mounted on a board body 401. In addition, an LED black light 1001 as an irradiation unit is provided in the center on the substrate body 401. The LED black light 1001 emits light having a wavelength of 400 nm or less. Note that light emitted from the LED black light 1001 includes visible light (having a wavelength of 360 nm).

  Further, a special resin 1002 that emits light when irradiated with the LED black light 1001 is applied on the solder resist of the substrate body 401. The special resin 1002 is, for example, white or translucent when the LED black light 1001 is not irradiated. For this resin, for example, strontium fluoborate doped with europium, barium silicide doped with lead, or the like is used. As for the color to emit light, any color can be used by changing the pigment.

  The main control board 1000 is accommodated in the board case 310. The substrate case 310 is rectangular and includes an upper surface portion 410 that covers the upper surface of the main control substrate 1000 and a side wall 411 that covers the side surfaces. The upper surface portion 410 of the substrate case 310 is configured by a surface substantially parallel to the substrate body 401 installed inside the substrate case 310. On the other hand, the side wall 411 is configured by a surface substantially perpendicular to the substrate body 401. Therefore, the substrate case 310 and the main control substrate 1000 form a rectangular parallelepiped. In the following description, regarding the upper surface portion 410 of the substrate case 310, the surface facing the main control substrate 1000 is referred to as an inner surface 1010, and the surface not facing the main control substrate 1000 is referred to as an outer surface 1011.

  A reflective portion 1020 for reflecting light from the LED black light 1001 toward the substrate body 401 is formed at a portion corresponding to the LED black light 1001 on the inner surface 1010 of the substrate case 310. As shown in FIG. 4, the reflecting portion 1020 has a concave cross section, and a special resin 1101 that emits light when irradiated with the LED black light 1001 is half-deposited on the surface. In addition, by changing the shape of the reflecting portion 1020, it is possible to make the light receiving sensor 122 condensing light efficiently. In FIG. 11, for convenience, the electronic component 402 shown in FIG. 10 is not shown.

  The substrate case 310 is made of a transparent member such as acrylic as described above. Further, the portion of the reflecting portion 1020 where the special resin 1101 is half-deposited is made translucent by the special resin 1101. Therefore, the substrate case 310 is configured to allow the inside to be visually observed from the outside.

(Action by irradiation of LED black light)
Next, the effect of irradiation with the LED black light 1001 will be described. For example, when the store clerk turns on the main power supply of the gaming machine 110, the LED black light 1001 is turned on. When the LED black light 1001 is turned on, the concave shape of the reflecting portion 1020 and the special resin 1101 are half-deposited, so that part of the light from the LED black light 1001 is effectively reflected toward the substrate body 401 side. Due to the reflected light, the special resin 1002 on the substrate body 401 emits light in a predetermined color. Note that the special resin 1002 on the substrate body 401 also emits light in a predetermined color by direct light from the LED black light 1001.

  On the other hand, part of the light from the LED black light 1001 is emitted to the outer surface 1011 side due to the shape of the reflecting portion 1020 and the half vapor deposition of the special resin 1101. At this time, light emitted to the outer surface 1011 side is emitted in a predetermined color by the special resin 1101. Therefore, when the LED black light 1001 is turned on when viewed from the outside, the reflecting portion 1020 of the substrate case 310 emits light and the substrate body 401 also emits light. In other words, when there is a fraudulent act in which the main control board 1000 is replaced, a predetermined light emission cannot be seen in the board case 310 or the board body 401, so that the fraudulent act can be easily found. ing.

  Similarly to the light described in the first embodiment, the light emitted to the outer surface 1011 side is received by the light receiving sensor 122, and whether or not the intensity is within a predetermined range by the hall computer 120, that is, main light. This is used to determine whether or not the control board 1000 has been illegally replaced.

  Due to this configuration, when the game machine 110 is inspected by the store clerk, when the game machine 110 is released from the installation frame, the store clerk simply looks at the back of the game machine 110 and the main control board 1000 is illegally replaced. You can easily check if it is not.

  In the second embodiment, the special resin 1002 and 1101 cause the substrate body 401 to develop a color (predetermined color) different from the emission color of the LED black light 1001. That is, the color of the LED black light 1001 can be easily distinguished from the color of the solder resist of the upper surface portion 410 of the substrate case 310 and the substrate body 401 that are colored by the irradiation of the LED black light 1001. . Therefore, it can be easily identified whether or not regular parts are used.

  In the second embodiment, the LED black light 1001 emits blue-violet light, whereas the upper surface portion 410 and the solder resist of the substrate case 310 are colored yellow-green. The color to be developed can be orange instead of yellow-green. Also, by changing the color former of the special resin 1002 and 1101 according to the number of production lots of the gaming machine 100, that is, by changing the color to be colored, it is easily identified whether or not regular parts are used. It is also possible.

  In the second embodiment, the portion where the special resin 1101 is half-deposited on the inner surface 1010 of the substrate case 310 is only the reflective portion 1020, but the entire surface of the inner surface 1010 may be used. Also, given characters, symbols, marks, etc. that can be grasped at a glance, for example, by providing irregularities on the inner surface 1010 of the substrate case 310, or by partially changing the thickness of vapor deposition of the special resin 1101 or the color of light emission. Etc. may be made to emit light. Furthermore, with respect to the special resin 1002 applied on the substrate main body 401, predetermined characters, symbols, marks, etc. that can be grasped at a glance by partially changing the thickness of vapor deposition of the special resin 1002 and the color of light emission. May be made to emit light.

  As described above, even when the main control board 1000 according to the second embodiment is used, the same effects as those of the first embodiment are obtained. In particular, the main control board 1000 according to the second embodiment includes an LED black light 1001 that irradiates light in a predetermined wavelength region on the substrate body 401, and the surface of the substrate body 401 is irradiated with light by the LED black light 1001. Since the resin coated with the special resin 1002 that emits light is used, the substrate body 401 can emit light.

  Therefore, when there is an illegal act in which the main control board 1000 is exchanged for an illegal one, the predetermined light emission cannot be seen, so that the illegal act can be easily found visually. Thereby, it is possible to prevent the spread of damage due to fraud without adversely affecting the electronic device.

  As described above, according to the abnormality detection device, the gaming machine, the abnormality detection method, and the abnormality detection program according to the present invention, it is possible to realize early detection of fraudulent acts with a simple configuration, and to prevent the spread of damage caused by fraud. It is possible to suppress fraud.
