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

  A liquid crystal display device 14 is provided in the center of the game area R1, and below the liquid crystal display device 14, a first starting winning opening 15, a second starting winning opening 16, a large winning opening 17 and an out opening 18 are provided in order from the top. I have. Further, on both sides of the special winning opening 17 and on the left side of the second starting winning opening 16, ordinary winning openings 20A, 20B and 20C are provided.

  The first winning opening 15, the second winning opening 16, and the normal winning openings 20A, 20B, 20C have a pocket structure protruding from the front surface of the game board 11 and having an opening on the upper surface. In addition, a pair of starting prize winning doors 16A, 16A usually stand up from both left and right opening edges of the second starting prize opening 16, and the winning of game balls into the second starting prize opening 16 is regulated. ing. Then, when a normal symbol hits (a so-called normal symbol hit) described later, the start winning doors 16A, 16A are tilted right and left for a predetermined period of time, so that a game ball can be awarded to the second start winning opening 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 a lower opening edge thereof. Normally, the special winning door 17A stands up and the winning in the special winning opening 17 is restricted, and when a special symbol described later (so-called special figure) is reached, the special winning door 17A is repeated for a predetermined time and a predetermined number of times. Falls forward, and a game ball can be awarded to the special winning opening 17.

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

  A start gate 19 is provided in a region on the left side of the liquid crystal display device 14 in the game region R1. Then, when the game ball passes through the starting gate 19, a hit / no-go determination is made with a probability of 1/2, and when the result of the determination becomes a hit (ie, a normal drawing hit), as described above, a predetermined time is reached. The start winning doors 16A, 16A are tilted right and left over the entire distance, so that a game ball can be won in the second starting winning port 16.

  When a game ball wins in either the first start winning opening 15 or the second start winning opening 16, a win / fail determination of a big hit game is performed, and the result of the determination is notified by a display on the liquid crystal display device 14. Specifically, the three numbers arranged side by side are scrolled up and down and then stopped and displayed. If the three displayed numbers are, for example, the same number, the result of the hit determination is a big hit. (I.e., per special figure), and it means that it was out of the way if it was not a cross. Then, when hitting a special map, as described above, the special winning door 17A falls down, and a large number of game balls can be awarded in the special winning opening 17, so that a large amount of winning balls can be obtained.

  The winning of the game ball to each of the winning ports 15 to 17, 20A to 20B and the starting 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 has a built-in detection coil surrounding the through hole. The winning switch 21 is connected to an input / output circuit 23 (interface circuit) of the main control board 22 of the pachinko gaming machine 10 via a relay circuit 29. For example, a voltage of a specific frequency is applied to the winning switch 21. ing. When a game ball having a higher magnetic permeability than air passes through the through-hole of the winning switch 21, the impedance of the detection coil of the winning switch 21 decreases, and the current of a specific frequency flowing through the input / output circuit 23 and the winning switch 21 is used as a reference. Greater than value. Then, a latch circuit (not shown) of the input / output circuit 23 enters a latch state, which 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 specifies which of the winning holes 15 to 17 and 20A to 20B the gaming ball has won, and performs the above-described jackpot determination or pays out the winning ball.

  By the way, when the electromagnetic wave of the specific frequency described above is received (received) on 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 malfunctions, so that the above-mentioned jackpot determination is made or the prize ball is paid out. Then, such a malfunction is intentionally generated, and an illegal act that obtains an illegal profit may be performed. In order to discover such misconduct, the pachinko gaming machine 10 is provided with an electromagnetic wave sensor 25 (corresponding to “illegal noise detecting means” according to the present invention).

  The electromagnetic wave sensor 25 is activated when an electromagnetic wave of a specific frequency is received with a predetermined intensity or more, and outputs a detection signal to the main control board 22. Then, the CPU 24 of the main control board 22 monitors the detection frequency from the electromagnetic wave sensor 25, and when the detection frequency exceeds a preset reference frequency (for example, three times per 10 minutes), for example, Then, a notification signal is transmitted to the management room of the gaming hall to that effect.

  The pachinko gaming machine 10 receives, for example, an AC of 24 [V] from an external AC power supply provided in each of the game islands of the game hall, and a first control system lower than its input voltage (ie, 24 [V]). DC of a voltage (for example, 12 [V], 5 [V]) and DC of a second voltage (for example, 37 [V]) for a non-control system higher than the input voltage (that is, 24 [V]). A power supply board 30 (see FIG. 2) for outputting a plurality of types of direct currents is provided. Then, 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, and the like shown in FIG. To control the supply of the electric power of the second voltage to the non-control system electric components (motor 10M, lamp 10L, etc.). In addition, a part of the second voltage is converted to a third voltage (for example, 16 V) by the DC-DC converter 32 and then applied to the non-control-system electric components.

  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 mounts the LEDs and the like mounted on the first and second lighting boards 51 and 52. Also, power is supplied to a lamp 10L (see FIG. 1) on the front of the pachinko gaming machine 10. In addition, a power line 35 for supplying the second voltage power from the lamp control circuit 28 to the first and second illuminated boards 51 and 52 passes through the first illuminated board 51 from the lamp control circuit 28. And extends to the second illumination substrate 52.

  The DC-DC converter 32 described above is mounted on the first illumination board 51 and has a known structure including a coil, a capacitor, a diode, and a switch element (for example, FET) (not shown). Then, 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]), reduces the second voltage to the third voltage, and reduces the motor 10M. Output to

  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 emitted from the power line 35 connected to the DC-DC converter 32, the electromagnetic wave sensor 25 may malfunction due to this. On the other hand, in the 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. 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 illumination board 52. The capacity of one capacitor C1 is 0.1 [μF], which is also provided in a conventional pachinko game 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. And, 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 may cause the electromagnetic wave sensor 25 to operate is generated. The radiation 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 in arranging 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 illuminated board 51 or the second illuminated board 52 or the first The electromagnetic wave sensor 25 can also be arranged between (near (the wiring of) the illuminated substrate 51 and the second illuminated substrate 52).
