  Hereinafter, an embodiment according to a pachinko gaming machine 10 as a “gaming machine” of the present invention will be described with reference to FIGS. 1 and 2. As shown in FIG. 1, the pachinko gaming machine 10 is provided with a glass window 10W on the front surface, and the game area R1 of the game board 11 can be visually recognized through the glass window 10W. Then, by turning the operation handle 12 at the lower right on the front surface of the pachinko gaming machine 10, the game balls stored in the upper plate 13 are driven into the upper part of the game area R1.

  A liquid crystal display device 14 is provided at the center of the game area R1, and a first start winning opening 15, a second starting winning opening 16, a big winning opening 17 and an out opening 18 are provided below the liquid crystal display device 14 in order from the top. Yes. Further, normal winning ports 20A, 20B, and 20C are provided on both sides of the big winning port 17 and on the left side of the second starting winning port 16.

  The first start winning port 15, the second start winning port 16, and the normal winning ports 20A, 20B, and 20C have a pocket structure that protrudes from the front surface of the game board 11 and has an opening on the upper surface. In addition, a pair of start winning doors 16A and 16A usually stand up from the left and right opening edges of the second start winning opening 16, and the winning of game balls to the second starting winning opening 16 is restricted. ing. When it comes to a normal symbol (to be referred to as a so-called common symbol), which will be described later, the start winning doors 16A and 16A fall to the left and right over a predetermined time, and it becomes possible to win a game ball in the second start winning port 16.

  The special winning opening 17 is formed in a laterally long rectangular shape and is opened on the front surface of the game board 11, and includes a special winning door 17A that rotates around the lower opening edge thereof. Normally, the big prize door 17A stands up and the prize winning to the big prize opening 17 is restricted, and when it comes to a special symbol (to be referred to as a special figure) described later, the big prize door 17A for a predetermined time and a predetermined number of times. Will fall forward, and it will be possible to win a game ball in the big prize opening 17.

  When a game ball wins each of the winning openings 15 to 17 and 20A to 20B, a predetermined plurality of game balls are paid out to the upper plate 13 as prize balls. In addition, the number of winning balls for winning in the big winning opening 17 is set to be larger than the number of winning balls for winning in other winning openings.

  A start gate 19 is provided in an area on the left side of the liquid crystal display device 14 in the game area R1. Then, when the game ball passes through the start gate 19, a hit / no-go determination is made with a probability of 1/2, and when the determination result is a hit (that is, per hit), as described above, at a predetermined time. The start winning doors 16A, 16A fall over to the left and right, and a game ball can be won into the second start winning port 16.

  When the game ball wins either the first start winning opening 15 or the second start winning opening 16, whether or not the big hit game is determined is determined, and the determination result is notified by displaying on the liquid crystal display device 14. Specifically, if each of the three numbers arranged horizontally is scrolled up and down and then stopped and displayed, and if the stopped and displayed three numbers are, for example, mokugome, the determination result is a big hit It means that it was (that is, per special figure), and if it was not a mean, it means that it was out of place. Then, when it comes to the special figure, as described above, the big winning door 17A falls forward and a large amount of game balls can be won in the big winning opening 17, and a large amount of winning balls can be obtained.

  The winning of game balls to each of the winning openings 15-17, 20A-20B and the start gate 19 is detected by a winning switch 21 (see FIG. 2). Although not shown, the winning switch 21 has a through-hole at one end of a domino-shaped main body and a detection coil that surrounds the through-hole. The winning switch 21 is connected to the input / output circuit 23 (interface circuit) of the main control board 22 of the pachinko gaming machine 10 via the relay circuit 29. For example, a voltage having a specific frequency is applied to the winning switch 21. ing. Then, a game ball having a higher magnetic permeability than air passes through the through hole of the winning switch 21, so that the impedance of the detection coil of the winning switch 21 decreases, and a current of a specific frequency flowing through the input / output circuit 23 and the winning switch 21 is a reference. Bigger than the value. Then, a latch circuit (not shown) of the input / output circuit 23 is in a latched state, and this is taken into the CPU 24 (corresponding to “control means” of the present invention) of the main control board 22. As a result, the CPU 24 identifies which of the winning openings 15 to 17 and 20A to 20B the game ball has won, and performs the above-mentioned jackpot determination or pays out the prize ball.

  By the way, when an electromagnetic wave having a specific frequency is applied (received) to the line 21C (see FIG. 2) connecting the winning switch 21 and the input / output circuit 23, the game ball passes through the through hole of the winning switch 21. In spite of this, the latch circuit described above malfunctions and the CPU 24 also malfunctions, and the above-described determination of whether or not the big hit is made or a prize ball is paid out. Then, there is a case where such a malfunction is intentionally generated and an illegal act for obtaining an illegal profit is performed. In order to find such a fraudulent act, the pachinko gaming machine 10 is provided with an electromagnetic wave sensor 25 (corresponding to “unfair noise detecting means” according to the present invention).

  The electromagnetic wave sensor 25 operates when receiving an electromagnetic wave having a specific frequency at a predetermined intensity or higher, and outputs a detection signal to the main control board 22. When the CPU 24 of the main control board 22 monitors the detection frequency from the electromagnetic wave sensor 25 and the detection frequency exceeds a preset reference frequency (for example, 3 times per 10 minutes), for example, A notification signal is transmitted to notify the management room of the game hall.

  For example, the pachinko gaming machine 10 receives AC of 24 [V] from an external AC power source provided in each gaming island of the game hall, and has a first control system lower than its input voltage (ie, 24 [V]). A direct current of a voltage (for example, 12 [V], 5 [V]) and a direct current of a second voltage (for example, 37 [V]) for the non-control system higher than the input voltage (that is, 24 [V]). A power supply board 30 (see FIG. 2) that outputs a plurality of types of direct current is included. 2 receives the first voltage directly or indirectly from the power supply board 30. The main control board 22, the sub control board 26, the display control circuit 40, the lamp control circuit 28, the payout control circuit 50, etc. shown in FIG. To control the supply of electric power of the second voltage to non-control electric parts (motor 10M, lamp 10L, etc.). A part of the second voltage is transformed to a third voltage (for example, 16 V) by the DC-DC converter 32 and then applied to the non-control system electrical component.

  Specifically, the lamp control circuit 28 receives the power of the second voltage from the power supply board 30 via the sub-control board 26, and the LEDs and the like mounted on the first electrical decoration board 51 and the second electrical decoration board 52 Alternatively, power is supplied to the lamp 10L (see FIG. 1) on the front surface of the pachinko gaming machine 10. In addition, the power line 35 for supplying the second voltage power from the lamp control circuit 28 to the first electrical decoration board 51 and the second electrical decoration board 52 passes through the first electrical decoration board 51 from the lamp control circuit 28. Extending to the second electric decoration board 52.

  The above-described DC-DC converter 32 is mounted on the first electrical decoration substrate 51 and has a known structure including a coil, a capacitor, a diode, and a switch element (for example, FET) (not shown). The DC-DC converter 32 receives the second voltage from the power line 35, performs switching at a predetermined switching frequency (for example, 260 [MHz]), and steps down the second voltage to the third voltage to reduce the motor 10M. To output.

  By the way, in the pachinko gaming machine 10 of the present embodiment, the specific frequency of the electromagnetic wave for operating the electromagnetic wave sensor 25 is a multiple of the switching frequency of the DC-DC converter 32. For this reason, when electromagnetic wave noise is radiated from the power line 35 connected to the DC-DC converter 32, the electromagnetic wave sensor 25 may malfunction. On the other hand, in this pachinko gaming machine 10, as shown in FIG. 2, the negative input electrode 32C of the DC-DC converter 32 is connected to the ground, and the electric power connected to the positive input electrode of the DC-DC converter 32 is connected. A pair of capacitors C1 and C2 are connected between the line 35 and the ground. The capacitors C1 and C2 are mounted on the second electric decoration board 52. The capacity of one capacitor C1 is 0.1 [μF], which is also provided in a conventional pachinko gaming machine. On the other hand, the capacity of the other capacitor C2 is 10 to 500 [μF], which is not provided in the conventional pachinko gaming machine. Since the capacitors C1 and C2 of 10 [μF] or more are connected between the power line 35 connected to the DC-DC converter 32 and the ground in this way, electromagnetic noise that causes the electromagnetic wave sensor 25 to operate is a power. Emission from the line 35 can be restricted. That is, erroneous detection by the electromagnetic wave sensor 25 can be prevented. This also increases the degree of freedom of the arrangement of the power line 35 of the DC-DC converter 32. For example, in the vicinity of the power line 35 (for example, near the first electrical decoration board 51 or the second electrical decoration board 52 or the first The electromagnetic wave sensor 25 can also be disposed between the electrical decoration board 51 and the second electrical decoration board 52 (near the wiring).
