  The present invention relates to a gaming machine, and more particularly, to a gaming machine (a ball game machine) such as a pachinko gaming machine such as a so-called seven machine, feathers, or a right-handed machine, or a combination type gaming machine (arrange ball gaming machine).

  2. Description of the Related Art Conventionally, there has been a problem of illegally gaining profit by irradiating an electronic circuit of a gaming machine with radio waves to malfunction the electronic circuit (so-called radio wave goto). In order to detect such fraud, it has been proposed to provide a gaming machine with a radio wave detection circuit including an oscillation circuit and a resonance circuit (see Patent Document 1).

JP 2008-3003 A

  However, since the gaming machine described in Patent Document 1 uses a radio wave detection circuit including a resonance circuit, a detectable frequency band is limited. For this reason, there is a problem that fraudulent acts using radio waves of frequencies other than the detectable frequency band cannot be detected. On the other hand, there is a problem that the radio wave detection circuit using the resonance circuit is expensive in order to obtain performance capable of detecting radio waves in a wide frequency band.

  SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to make it possible to detect fraud using radio waves without being affected by the frequency band to be used.

In order to achieve the above object, the present invention is a gaming machine including a radio wave detection circuit that detects an electromagnetic wave when the electromagnetic wave is irradiated from the outside,
The radio wave detection circuit receives an electromagnetic wave to generate an induced voltage, outputs a predetermined reference voltage, and when the induced voltage is generated by the antenna, a reference voltage output line that does not vary, and A voltage lower than a reference voltage is output, and when an induced voltage is generated in the antenna, an induced voltage output line that outputs a voltage higher than the reference voltage, a voltage output from the reference voltage line, and an induced voltage output line are Comparing means for outputting a voltage indicating a magnitude relationship with the voltage to be output is provided.

  The radio wave detection circuit of the present invention has a non-resonant circuit configuration that detects an induced voltage generated in an antenna by electromagnetic waves. For this reason, the frequency band of the detectable electromagnetic wave is not limited as compared with the configuration in which the radio wave is sensed using the resonance circuit, and the electromagnetic wave of any frequency band can be detected. As a result, it is possible to detect fraudulent acts that cause an electronic circuit to malfunction by irradiating an electromagnetic wave from outside and generating an induced voltage in the wiring of the electronic circuit by electromagnetic induction without being affected by the frequency band to be used. Become.

  In the gaming machine of the present invention, the reference voltage output line includes a first diode and a capacitor connected in parallel with the first diode. When an induced voltage is generated in the antenna, The induced voltage is not detected by one diode, and the voltage is not changed. The induced voltage output line is provided with a second diode having the same configuration as the first diode, and is induced by the antenna. When a voltage is generated, the induced voltage is detected by the second diode to generate a DC voltage, and a voltage higher than the reference voltage is output.

  As a result, the induced current flowing through the reference voltage output line passes through the capacitor connected in parallel with the first diode, and is not detected by the first diode and does not become a direct current. As a result, even when an induced voltage is generated in the antenna, the voltage of the reference voltage output line can be prevented from changing. On the other hand, in the induced voltage output line, the induced voltage generated in the antenna is detected by the second diode. As a result, the induced voltage generated in the antenna becomes a DC voltage, and the voltage of the induced voltage output line can be increased.

  In addition, the gaming machine of the present invention is characterized in that the radio wave detection circuit is provided in a main control unit that controls the progress of the entire game.

  Accordingly, the main control unit can be configured to output an error to the sub-control unit that controls display and sound when an external electromagnetic wave is detected based on the output state of the radio wave detection circuit. As a result, the sub-control unit that has received the error output can perform error notification to the effect that an abnormality has occurred using a display or sound. Furthermore, the main control unit can output an error to the outside when the electromagnetic wave is detected by the radio wave detection circuit. Furthermore, when the electromagnetic wave is detected by the radio wave detection circuit, the main control unit can stop the progress of the game by stopping various controls of the gaming machine and shutting off the power.

  With the configuration of the present invention described above, it is possible to detect fraud using radio waves without being affected by the frequency band to be used.

  The first decorative member 50 is provided with a plurality of LEDs, and a combination of these LEDs constitutes a normal symbol display portion 51, a general symbol hold display portion 52, and a special symbol hold display portion 53. Similarly, the second decorative member 60 is provided with a plurality of LEDs, and a special symbol display unit 61 is configured by a combination of these LEDs.

  The normal symbol display part 51 is comprised from one LED, and a normal symbol is displayed by this LED. In the normal symbol display unit 51, the normal symbol variation display and stop display are performed. In the normal symbol display unit 51, the normal symbol starts to change when the game ball passes through the normal symbol operating gate 27, and after a predetermined time has passed, the normal symbol hits and stops display in the normal symbol display mode or the dismissed normal symbol display mode. Is done. Then, when the normal symbol is stopped and displayed in the preset normal symbol display mode, the second start port 28b is opened for a predetermined time (for example, 0.1 second).

  In the present embodiment, a random number for determining whether or not a normal symbol is provided is prepared. This random number for determining whether or not a normal symbol is used determines whether or not the second starting port 28b is activated when the game ball passes through the normal symbol operating gate 27. This is used to determine whether or not a normal symbol is appropriate. The normal symbol success / failure random number is set in advance with a hit value, and the normal symbol success / failure determination random number acquired at the timing when the game ball passes the normal symbol operation gate 27 matches the win value. Determined. When it is determined to be a winning, the normal symbol that is stopped and displayed on the normal symbol display unit 51 is determined as the display mode of the winning normal symbol. On the other hand, when it is determined to be out (when the acquired normal symbol success / failure random number does not match the winning value), the normal symbol stopped and displayed in the normal symbol display unit 51 is determined as the display mode of the out of normal symbol. Is done. Note that the determination of whether or not the normal symbol is correct and the determination of the stop symbol of the normal symbol are performed by the main control unit 200 described later.

  Here, normal symbol holding will be described. The normal symbol hold display section 52 displays the normal symbol hold number, and the number of game balls that have passed through the normal symbol operation gate 27 can be held up to the maximum hold number (four in this embodiment). Each time the next normal symbol win / fail determination is made and the normal symbol variation display is started, the number of unstarted times (the number of reservations) is consumed, and the number of normal symbol reservations is decreased by one. The general-purpose hold display unit 52 includes two LEDs, and can display the number of holds with an upper limit of four by combining turning off, lighting, and blinking of the two LEDs. The normal symbol holding and holding digest are performed by the main control unit 200 described later. Along with the holding of the normal symbol, a random number for determining whether or not the normal symbol is stored in a predetermined area of the RAM of the main control unit 200.

  Next, the special symbol will be described. The special symbol display unit 61 is composed of seven LEDs, and special symbols are displayed by these LEDs. Each LED constituting the special symbol display unit 61 can be turned on and off, and a plurality of special symbol display modes can be displayed by a combination of turning on and off the LEDs. Of the combinations of special symbols displayed by the seven LEDs, a specific combination is set as a hit special symbol (big hit symbol), and a portion other than the hit special symbol is set off as a special symbol (off symbol). ing. In this embodiment, the special symbol variation display is performed by blinking display in which each LED is repeatedly turned on and off.

  In the special symbol display unit 61, when the game ball enters the start port 28, the special symbol starts to change, and after a predetermined time has elapsed, the special symbol is stopped and displayed as a big hit symbol or a missed symbol. In the present embodiment, a first special symbol success / failure determination random number that is acquired when a game ball enters the start opening 28 and is used for determining whether or not to execute a jackpot game (special game) is provided. It has been. Furthermore, a special symbol determining random number for determining a stop symbol of the special symbol is provided.

  As the game ball enters the start port 28, a special symbol success / failure determination random number and a special symbol determination random number are acquired, and the acquired special symbol success / failure determination random number and special symbol determination random number are stored in the main control unit 200. Is stored in a predetermined area (holding storage area) of the RAM.

  Here, the holding of special symbols will be described. The special symbol hold display unit 53 is composed of two LEDs, and can display the number of holds with an upper limit of four by combining turning off, turning on, and blinking of the two LEDs.

  The number of game balls that have entered the starting port 28 can be reserved until the maximum number of reservations (four in this embodiment) is reached as the number of special symbol reservations. The first special symbol hold count is digested every time the special symbol success / failure determination is performed and the variable display of the first special symbol is started, and decreases by one. Note that special symbol hold (acquisition / storage of special symbol random numbers) and hold digest (special symbol success / failure determination) are performed by the main control unit 200 described later.

  The special symbol success / failure determination is performed when the special symbol starts the variable display. The special symbol success / failure determination random number is set with a winning value for winning / failure determination, and the special symbol success / failure determination random number acquired at the timing when the game ball enters the start port 28 matches the winning value. A big hit is determined.

  Then, when the result of the special symbol success / failure determination is a big hit, the special symbol stopped and displayed on the special symbol display unit 61 is determined to be a big hit symbol (probability big hit symbol or normal big hit symbol). Note that the type of jackpot symbol of the special symbol is determined based on a special symbol determining random number. On the other hand, when the special symbol winning / failing determination is out of place, the special symbol that is stopped and displayed by the special symbol display unit 61 is determined to be the out symbol.

  The special symbol is configured to change and display according to a predetermined change pattern. This variation pattern defines the variation time of the special symbol and the presence / absence of the reach effect in the variation (effect content). The variation pattern of the special symbol is selected by lottery from a variation pattern table (variation pattern storage means) in which a plurality of variation patterns are stored when the special symbol success / failure determination is executed.

  A plurality of special symbol variation pattern tables are prepared, and are selected and used according to the gaming state. The plurality of variation pattern tables include a hit variation pattern table selected when the success / failure determination result is a big hit, and a miss variation pattern table selected when the success / failure determination result is unacceptable.

  Further, the determination of whether or not the special symbol is determined, the determination of the variation pattern of the special symbol, the determination of the special symbol stop symbol, the special symbol variation display and the stop display are performed by the main control unit 200 described later.

  Next, the jackpot game (special game) will be described. When the first special symbol stopped and displayed on the special symbol display unit 61 is a hit special symbol (when the result of the special symbol determination is a big hit), the main control unit 200 is relatively advantageous to the player. A big hit game (special game) is started. The big hit game is to give a player a profit (prize ball) with respect to entering the game ball into the big prize opening 33a by operating the big prize device 33, in other words, by opening and closing the big prize opening 33a a plurality of times. The main control unit 200 corresponds to the jackpot game execution means of the present invention. The big hit game is realized by repeatedly executing a special electric accessory game process described later.

  During the big hit game (during special game), the big prize device 33 is operated, and a predetermined number of prize balls (for example, 15 for one pitch) according to the number of game balls entered into the big prize opening 33a. Award balls). Specifically, when the big hit game is started, the big prize opening device (special electric accessory) 33 is continuously operated and the big prize opening opening / closing operation for switching the big prize opening 33a between the open state and the closed state is continuously performed a plurality of times. Done. With the start of the operation of the special winning device 33, the special winning opening 33a is opened. This open state is ended when a predetermined end condition is established, and the open special winning opening 33a is closed. As a predetermined end condition, when the opening time of the big winning opening 33a reaches a predetermined time (30 seconds in the present embodiment), or when the number of game balls entered into the opened large winning opening 33a is a predetermined number (this execution) In the example, it is possible to reach 10).

  When it is assumed that one round is from the start to the end of the open state of the big winning opening 33a, the big hit game is ended by performing a predetermined number of rounds. In the grand prize winning device 33, after the opening of the big prize winning opening 33a is finished, that is, after a predetermined time (for example, 30 seconds) has passed since the big winning prize opening 33a is closed, the big winning prize opening 33a is again opened. Round begins. The opening / closing operation of the grand prize winning port 33a in which one round is from the start to the end of the big winning port 33a is repeated until a predetermined maximum number of continuous rounds (15 rounds in this embodiment) is completed.

  In the gaming machine of this embodiment, after the big hit game is finished, a specific game (so-called short-time game and probability variable game) in which the variable time shortening function, the open time extending function, and the probability varying function are activated is started. Multiple types of jackpots are set in the special symbol success / failure determination. If the result of the special symbol success / failure determination is a normal jackpot (the special symbol stop symbol is a normal jackpot symbol), after the jackpot game ends, In the case where the result of the special symbol success / failure determination is a probable big hit (the special symbol stop symbol is a probable big hit symbol), the probable variation game is started after the big hit game ends.

  When the result of the special symbol success / failure determination is a normal jackpot (the special symbol stop symbol is a normal jackpot symbol), after the jackpot game is over, the variable time shortening function and the opening time extension for extending the opening time of the second start port 28b are extended. The function is activated and the short-time game is started. The variation time shortening function (variation time shortening means) includes a normal symbol variation time shortening function for shortening the normal symbol variation time and a special symbol variation time shortening function for shortening the special symbol variation time. The fluctuation time shortening function and the opening time extension function operate after the big hit game is finished until the next big hit game is started, or until the number of fluctuations of the special symbol reaches a predetermined number (100 times in this example). . Due to the operation of the opening time extension function, the opening time of the second start port 28b is, for example, “4.5 seconds (1.5 seconds × 3 times or 4.times. 5 seconds x 1 release, etc.) ". As a result, the frequency of entering the game ball into the second start port 28b becomes higher than normal (when the opening extension function is not activated). The variable time shortening function and the open time extending function are activated or stopped under the control of the main control unit 200.

  If the result of the special symbol success / failure determination is a probable big hit (the stop symbol of the special symbol is a probable big hit symbol), after the big hit game ends, the probability variation function starts to operate, and the probable variable game is started. In the probability variation game, in addition to the above-mentioned variation time shortening function and opening time extension function, a probability variation function (probability variation means) that changes (improves) the probability of the special symbol success / failure determination, that is, the probability that the special symbol is stopped and displayed as a big hit symbol. Operate. While the probability variation function is in operation, the probability of the special symbol success / failure determination is improved by increasing the hit value for the success / failure determination. The probability variation function operates after the jackpot game is over until the next jackpot game is started. Note that the probability variation game is realized by the control of the main control unit 200.

  Next, the effect symbols displayed on the effect display device 25 will be described. The display area of the effect display device 25 is provided with an effect symbol display unit for displaying effect symbols. The effect symbol of the effect symbol display unit is displayed in conjunction with the special symbol change display and the stop display of the special symbol display unit 61.

  The effect symbol display unit is composed of three symbol display areas including a left symbol display area in which a left symbol is displayed, a middle symbol display area in which a middle symbol is displayed, and a right symbol display area in which a right symbol is displayed. . Each symbol display area has a symbol variation direction set in a direction substantially orthogonal to the arrangement direction of these display areas, in this case, in the vertical direction (vertical direction). Each symbol display area can display symbols consisting of “1” to “9”.

  The effect symbol starts to be displayed when the special symbol starts to be changed. When the special symbol is stopped and displayed in any of the symbols, the effect symbol is stopped and displayed in accordance with the stop symbol of the special symbol. That is, the effect symbol starts to be displayed in synchronization with the special symbol, and ends and stops display in synchronization with the special symbol. In the effect design, a combination of even symbols with the same three digits corresponds to a normal jackpot symbol of a special symbol, and a combination of odd symbols with the same three digits corresponds to a probability variation jackpot symbol of a special symbol. A combination of symbols other than these corresponds to the off symbol of the special symbol.

  The determination of the variation pattern (variation pattern) and stop symbol of the effect symbol is configured to be performed by the sub-control unit 260 based on the variation pattern designation command transmitted from the main control unit 200. Here, the variation pattern designation command transmitted from the main control unit 200 indicates a variation pattern of a special symbol. Specifically, two digits of the variation time of the special symbol and the three-digit effect symbol are the same. The contents of effects such as the presence / absence of a reach effect (an effect indicating that a state where there is a possibility of reaching a big hit is continued) stopped with a symbol is shown. The main control unit 200 determines a variation pattern of the special symbol at random (by random number lottery) according to the determination result of the special symbol. Based on the special symbol variation pattern determined by the main control unit 200, the sub-control unit 260 determines the effect pattern of the effect symbol displayed on the effect symbol display unit 25a.

  Next, the radio wave detection circuit 300 provided in the main control unit 200 will be described. The radio wave detection circuit 300 is configured to detect an induced voltage that may affect various electronic circuits of the gaming machine 1.

  As described above with reference to FIG. 3, the main control board case 105 that houses the main control board 200a is provided on the back side of the start opening 28 of the game board 20, and therefore the main control board 200a detects the start opening entering ball. It is located near the switch 28s. The radio wave detection circuit 300 of this embodiment is provided inside the main control board 200a.

  This is because the start-entry ball detection switch 28s is often the target of fraudulent acts that are irradiated with radio waves, and by arranging the radio-wave detection circuit 300 near the start-entry ball detection switch 28s, This is to make it easier to detect. Of course, by increasing the sensitivity of the radio wave detection circuit 300, it is possible to detect unauthorized radio waves even at a location away from the starting entrance ball detection switch 28s. However, in the case of the gaming machine 1, it is usual that a plurality of game machines are arranged adjacent to each other in the game arcade, and by detecting the radio wave to the adjacent gaming machine 1 by increasing the sensitivity of the radio wave detection circuit 300, Since this is not preferable, in this embodiment, the radio wave detection circuit 300 is installed at a location (main control board 200a) close to a location (a start entrance ball detection switch 28s) where an unauthorized radio wave is expected to be irradiated. .

  FIG. 5 is a circuit diagram of the radio wave detection circuit 300. The radio wave detection circuit 300 is provided with a connector 301 for connecting to the outside. The connector 301 is provided with a power supply terminal Vcc, an output terminal OUT, and a ground terminal GND. In this embodiment, the power supply voltage supplied from the power supply terminal Vcc is set to 12 volts. The output terminal OUT of the connector 301 is connected to the CPU 200b of the main control unit 200.

  A first resistor 302, a second resistor 303, and a third resistor 304 are connected in series between the power supply terminal Vcc and the ground terminal GND, and these resistors 302 to 304 are configured as voltage dividing resistors. The second resistor 303 of this embodiment is configured as a variable resistor. A reference voltage output line L1 is connected between the first resistor 302 and the second resistor 303, and an induced voltage output line L2 is connected between the second resistor 303 and the third resistor 304. The reference voltage output line L1 outputs a predetermined reference voltage, and the induced voltage output line L2 outputs a voltage lower than the reference voltage. The reference voltage output line L1 is provided with a first diode 305, and the induced voltage output line L2 is provided with a second diode 306 having the same configuration as the first diode 305. A first capacitor 307 is connected in parallel to the first diode 305 in the reference voltage output line L1. The voltages of the reference voltage output line L1 and the induced voltage output line L2 are input to the comparator 308. The comparator 308 constitutes a comparison unit that outputs a voltage indicating a magnitude relationship between the voltage V1 output from the reference voltage line L1 and the voltage V2 output from the induced voltage output line L2. The output line of the comparator 308 is connected to the output terminal OUT of the connector 301, and the output voltage of the comparator 308 is input to the CPU 200 b of the main control unit 200.

  A fourth resistor 309 and a second capacitor 310 are provided between the reference voltage output line L1 and the ground terminal GND in order to stabilize the voltage V1 of the reference voltage output line L1. A fifth resistor 311 and a third capacitor 312 are provided between the induced voltage output line L2 and the ground terminal GND in order to stabilize the voltage V2 of the induced voltage output line L2.

  The radio wave detection circuit 300 is provided with an antenna 313 that receives an electromagnetic wave irradiated from the outside and generates an induced voltage. The antenna 313 is configured as a wiring connected in parallel to the first resistor 302 and the second resistor 303. In FIG. 5, the antenna 313 is described as a coil, but in reality, the entire loop-shaped wiring extending from the power supply terminal Vcc to the second resistor 303 and the third resistor 304 functions as an antenna. The antenna 313 is connected in series with a fourth capacitor 314 for cutting a DC component.

  In this embodiment, the resistance value R1 of the first resistor 302 is 470 kΩ, the resistance value R2 of the second resistor 303 is 20 kΩ, the resistance value R3 of the third resistor 304 is 470 kΩ, the resistance value R4 of the fourth resistor 309 and the fifth resistor The resistance value R5 of 311 is 1 MΩ, and the capacitances of the first capacitor 307 to the fourth capacitor 314 are 220 pF.

The voltage V1 of the reference voltage output line L1 is obtained by dividing the power supply voltage 12 volts by the first resistor 302 and the second and third resistors 303 and 304, and V1 = Vcc × ((R2 + R3) / (R1 + R2 + R3)) by -V _F is obtained. Similarly, the voltage V2 of the induction voltage output line L2 is obtained by dividing the power supply voltage 12 volts by the first and second resistors 302 and 304 and the third resistor 304, and V2 = Vcc × (R3 / (R1 + R2 + R3) ) obtained by -V _F. V _F is a drop voltage of the diodes 305 and 306. Since these diodes 305 and 306 have the same configuration, the drop voltage is also the same. In this embodiment, the drop voltage is 0.6 volts. For this reason, the voltage V1 of the reference voltage output line L1 is 5.5 volts, and the voltage V2 of the induced voltage output line L2 is 5.2 volts. For this reason, in a normal state in which no electromagnetic waves are irradiated from the outside, the voltage V1 of the reference voltage output line L1> the voltage V2 of the induced voltage output line L2, and the output state of the comparator 308 is a high output.

  A sixth resistor 315 is provided between the power supply terminal Vcc and the output side of the comparator 308. The sixth resistor 315 is a pull-up resistor, and ensures the high output of the comparator 308. The sixth resistor 315 is connected in series with an LED 316 that switches on / off according to the output state of the comparator 308. Further, a fifth capacitor 317 is provided between the output side of the comparator 308 and the ground terminal GND for preventing chattering of the output of the comparator 308. Further, a sixth capacitor 318 is provided as a bypass capacitor between the power supply terminal Vcc and the ground terminal GND.

  Next, the operation of the radio wave detection circuit 300 when an electromagnetic wave is irradiated from the outside will be described.

  When electromagnetic waves are applied to the gaming machine 1 from the outside, an induced voltage is generated at the antenna 313. Then, the induced voltage whose DC component is cut by the fourth capacitor 314 is detected by the second diode 306 of the induced voltage output line L2, and further smoothed by the third capacitor 312. As a result, the induced voltage generated in the antenna 313 becomes a DC voltage, and increases the voltage V2 of the induced voltage output line L2. On the other hand, since the second resistor 303 has a small resistance value for causing a potential difference between the reference voltage output line L1 and the induced voltage output line L2, the induced voltage generated by the antenna 313 is also applied to the reference voltage output line L1. Is done. However, since the induced current flowing in the reference voltage output line L1 passes through the first capacitor 307 connected in parallel with the first diode 305, it is not detected by the first diode 305 and does not become a direct current. For this reason, even if an induced voltage is generated in the antenna 313, the voltage V1 of the reference voltage output line L1 does not change.

  As a result, when an induced voltage is generated in the antenna 313, only the voltage V2 of the induced voltage output line L2 increases in proportion to the magnitude of the induced voltage, that is, the magnitude of the electromagnetic wave irradiated from the outside. Then, when the voltage V2 of the induced voltage output line L2 becomes larger than the voltage V1 of the reference voltage output line L1, the output state of the comparator 308 is switched from the high output to the low output. Therefore, by monitoring the output state of the comparator 308, it is possible to detect the irradiation of electromagnetic waves from the outside.

  The radio wave detection circuit 300 of this embodiment includes an LED 316 for visually confirming external electromagnetic wave irradiation. The LED 316 is in an extinguished state in which no current flows in a normal state where the output state of the comparator 308 is a high output. On the other hand, when the output state of the comparator 308 becomes a low output, a current flows through the LED 316 and the lighting state is set. For this reason, it is possible to visually grasp whether or not the radio wave detection circuit 300 has detected an external electromagnetic wave, depending on the lighting state of the LED 316.

  The radio wave detection circuit 300 according to this embodiment described above has a configuration for detecting the induced voltage generated in the antenna 313 by electromagnetic waves, that is, a non-resonant type configuration for detecting induced noise. For this reason, the frequency band of the detectable electromagnetic wave is not limited as compared with the configuration in which the radio wave is sensed using the resonance circuit, and the electromagnetic wave of any frequency band can be detected. As a result, it is possible to detect an improper action that causes the electronic circuit to malfunction by irradiating an electromagnetic wave from the outside and generating an induced voltage (noise) in the wiring of the electronic circuit by electromagnetic induction. Furthermore, according to the configuration of the radio wave detection circuit 300 of the present embodiment, it is possible to detect electromagnetic waves with a simple configuration without using a resonance circuit, and thus it is possible to reduce the cost.

  In this embodiment, since the radio wave detection circuit 300 is provided in the main control unit 200, the main control unit 200 detects an electromagnetic wave from the outside based on the output state of the output terminal OUT of the radio wave detection circuit 300. In addition, an error output can be made to the sub-control unit 260. Receiving the error output, the sub-control unit 260 can notify the error that an abnormality has occurred using the display in the display area of the effect display device 25 and the sound from the speakers 10a to 10d. Further, when the radio wave detection circuit 300 detects an electromagnetic wave, the main control unit 200 can output an error to the outside. Furthermore, when the main control unit 200 detects an electromagnetic wave by the radio wave detection circuit 300, the main control unit 200 stops various controls of the gaming machine 1 or shuts off the power supply, and stops the progress of the game, thereby preventing the influence of illegal acts. It can be suppressed as much as possible.

  In addition, in the radio wave detection circuit 300 according to the present embodiment, since an induced voltage that may affect an electronic circuit is a detection target, noise due to surge voltage, electromagnetic induction, and the like are also included in the detection target. However, although electromagnetic induction is difficult to receive induction because of its low frequency, in this embodiment, the antenna 313 is configured in a loop shape connected to the power supply terminal Vcc to improve sensitivity. As described above, in this embodiment, the antenna 313 is connected to the power supply terminal Vcc to improve the sensitivity. Therefore, the antenna 313 can be downsized.

  Further, in the radio wave detection circuit 300 of the present embodiment, the sensitivity of the radio wave detection circuit 300 can be adjusted by adjusting the potential difference between the reference voltage output line L1 and the induced voltage output line L2. In the radio wave detection circuit 300 of the present embodiment, the potential difference between the reference voltage output line L1 and the induced voltage output line L2 can be changed by the resistance value of the second resistor 303. In particular, in the radio wave detection circuit 300 according to the present embodiment, since the variable resistor is used as the second resistor 303, the sensitivity of the radio wave detection circuit 300 can be easily adjusted. Specifically, by reducing the resistance value of the second resistor 303, the potential difference between the reference voltage output line L1 and the induced voltage output line L2 is reduced, and the sensitivity of the radio wave detection circuit 300 can be increased. By increasing the resistance value of the resistor 303, the potential difference between the reference voltage output line L1 and the induced voltage output line L2 increases, and the sensitivity of the radio wave detection circuit 300 can be reduced.

(Other embodiments)
As mentioned above, although the Example of this invention was described, this invention is not limited to this, Unless it deviates from the range described in each claim, it is not limited to the description word of each claim, and those skilled in the art Improvements based on the knowledge that a person skilled in the art normally has can be added as appropriate to the extent that they can be easily replaced.

  For example, in the above embodiment, the radio wave detection circuit 300 is provided in the main control unit 200. However, the present invention is not limited thereto, and the radio wave detection circuit 300 may be provided in other control units such as the payout control unit 230 and the sub control unit 260. Good.

  For example, when the radio wave detection circuit 300 is provided on the payout control board 230a that constitutes the payout control unit 230, the payout control board 230a is disposed below the main control board 200a, and the radio wave detection circuit 300 enters the start port. Since it is far from the sphere detection switch 28s, it may be necessary to slightly increase the sensitivity of the radio wave detection circuit 300. Further, as shown in FIG. 4, the main control board 200a and the payout control board 230a are connected so as to be capable of bidirectional communication. Therefore, when a radio wave is detected by the radio wave detection circuit 300 provided on the payout control board 230a, an error signal can be sent from the payout control unit 230 to the main control unit 200. The main control unit 200 can be configured to output an error to the sub control unit 260.

  For example, when the radio wave control detection circuit 300 is provided on the sub control board 260a constituting the sub control unit 260, the sub control board 260a is provided above the main control board 200a. However, it may be necessary to slightly increase the sensitivity of the radio wave detection circuit 300 since the distance from the start entrance ball detection switch 28s is increased. In this case, as shown in FIG. 4, the one-way communication from the main control board 200a to the sub control board 260a is performed between the main control board 200a and the sub control board 260a. For this reason, when a radio wave is detected by the radio wave detection circuit 300 provided on the sub-control board 260a, the sub-control unit 260 may output an error without being informed by the main control unit 200. The sub-control unit 260 can perform an error notification that an abnormality has occurred using the display in the display area of the effect display device 25 and the sound from the speakers 10a to 10d.

  In addition, the radio wave detection circuit 300 can be disposed in a place other than the main control board 200a, the payout control board 230a, or the sub control board 260a by providing a relay board dedicated to the radio wave detection circuit 300. Since the place to be irradiated with the illegal radio wave is not necessarily the start entrance ball detection switch 28s, a relay board dedicated to the radio wave detection circuit 300 may be disposed at a position where the radio wave is expected to be irradiated. In this case, it is desirable to configure so that a signal can be transmitted from the relay board dedicated to the radio wave detection circuit 300 to the main control board 200a for error processing when an illegal radio wave is detected.

  In the above embodiment, a variable resistor is used so that the sensitivity of the second resistor 303 can be adjusted. However, a fixed resistor may be used when the resistance value is fixed by a design value or trial manufacture. As a result, the radio wave detection circuit 300 of the present invention can be mounted on a device that is restricted from using a variable resistor.

  In the above embodiment, when the radio wave detection circuit 300 detects a radio wave, the main control unit 200 immediately outputs an error to the sub control unit 260. However, some of the fraudsters irradiate the gaming machine 1 with unauthorized radio waves while always playing games so as not to be suspicious. For this reason, an error may be output under AND conditions that the game is in progress and that an illegal radio wave has been emitted. That is, the main control board 200a can detect that the player is playing a game, that is, the game ball is being fired, via the launch control board 250a and the payout control board 230a. Therefore, the main control unit 200 may be configured to output an error to the sub-control unit 260 only when a game ball is being fired and a radio wave is detected by the radio wave detection circuit 300.

  In the above embodiment, the antenna 313 is connected to the power supply terminal Vcc side. However, the present invention is not limited to this, and the antenna 313 may be connected to the ground terminal GND side as shown in FIG.

  In the above embodiment, an example in which the present invention is applied to a pachinko gaming machine (bullet ball gaming machine) has been described. However, the present invention can also be applied to different types of gaming machines such as a revolving gaming machine. .
