Description

  The present invention relates to a gaming machine.

  Conventionally, in a pachinko gaming machine which is one of the gaming machines, various winning devices are arranged on the game board, and each of these winning devices detects the winning of a game ball to each winning device. The detection switch is arranged. In addition, a technique for preventing an illegal act called “radio wave”, which is performed for the purpose of receiving an illegal payout by malfunctioning the detection switch, has been proposed.

  For example, Patent Document 1 describes the following technology. That is, the game ball detector for a ball game machine described in Patent Document 1 is sensitive to an electromagnetic wave or a magnetic field and a ball detection unit that detects the passage of the game ball by a change in an electrical physical quantity when the game ball passes. A fraud detection unit that detects fraud by a change in electrical physical quantity at the time, and an output blocking unit that blocks output of a detection signal from the sphere detection unit when the fraud detection unit detects fraud.

  Patent Document 2 describes the following technique. That is, in the gaming ball detection device and the gaming machine described in Patent Document 2, the CPU starts measuring time when the signal input from the start sensor is the first detection signal. The measured time is added to the variable T over time. Next, when the second detection signal is input, the CPU ends the time measurement. Next, the CPU assigns 1 to the variable n if the variable T is equal to or greater than the threshold value Tth, and assigns 0 to the variable n if the variable T is smaller than the threshold value Tth. If the variable n is 1, the CPU determines that the game ball has passed through the start port. On the other hand, if the variable n is 0, the CPU determines that there is an abnormality because it is not a normal game ball passing. .

In addition, the game control unit 200 includes a variation pattern selection unit 235 and a game progress control unit 236 as functional units that execute processing associated with special symbol variation.
Furthermore, the game control unit 200 is a function unit that executes operation control of various types of objects and data processing related to a prize ball, etc., as a function unit for a prize winning opening operation control unit 238, an electric tulip operation control unit 239, and a prize ball processing unit 240. And an output control unit 241 and a random number control unit 242.

The special symbol lottery unit 231 performs a special symbol lottery when a game ball wins the first start port 121 or the second start port 122. That is, when the special symbol lottery unit 231 acquires a signal from the first start port detection unit or the second start port detection unit that the game ball has won the first start port 121 or the second start port 122, Draw a special symbol.
The normal symbol lottery unit 232 performs the normal symbol lottery when the game ball passes through the gate 124. That is, the normal symbol lottery unit 232 performs the normal symbol lottery when the gate detection unit obtains a signal that the game ball has passed through the gate 124.
When a special symbol lottery is performed, the special symbol variation control unit 233 controls the variation of the special symbol according to the lottery result.

The special symbol lottery result determination unit 234, when a special symbol lottery is performed, the lottery result is “whether it is a big hit”, “a type of jackpot when a big winner is won”, “not a big winner It is determined whether or not it is a small hit or not.
Here, the types of “big hit” include “long hit” in which a long jackpot game time can be expected to be paid out, and “short hit” in which a big hit game time is short. For example, in the “long win”, a round that is maintained until the open state of the big winning opening 125 satisfies a predetermined condition (for example, 30 seconds have passed or 10 game balls have been won) is repeated, for example, 15 times. In the “short win”, the round at the special winning opening 125 is repeated twice, for example.

  Furthermore, the “long win” is a jackpot (“specific symbol A” in the subsequent stage), which is also called “15 round probability per change” that generates both a probability change (probability change) gaming state and a time reduction (time reduction) game state after the end of the jackpot game And a jackpot called “ordinary jackpot” (a jackpot in the “normal symbol” in the subsequent stage) that generates only the short-time gaming state and does not generate the probability variation gaming state after the jackpot game ends. The “short win” is a so-called “two-round probable hit” (a big hit in the “specific symbol B” in the subsequent stage) that generates a probability variation gaming state after the jackpot game ends and does not generate a short-time gaming state.

In addition, the “small winning” in the case of not winning a big win, for example, a small winning game is performed in which the big winning opening 125 is opened and closed twice, and the gaming state at the time of winning the small win is continued even after the winning is completed. It is a win (winning with the “small hit symbol” in the latter part) That is, when the game state at the time of winning the small hit is the probability variation game state, the probability variation game state is continued even after the end of the small hit game, and the game state does not shift. Similarly, if the gaming state at the time of winning the small hit is a normal gaming state (normal gaming state) in which neither probability fluctuation nor time reduction is made, the normal gaming state is continued even after the end of the small hitting game, The gaming state does not transition.
Further, in the “missing”, neither the “big hit” nor the “small winning” is set, and none of the above-described gaming states advantageous to the player is set (setting of the “missing symbol” in the subsequent stage).

  In the determination by the special symbol lottery result determination unit 234, the probability that the lottery result of the special symbol based on the winning at the second starting port 122 will be per 15 round probability change is special based on the winning at the first starting port 121. Determination is made so that the symbol lottery result is higher than the probability of being probable 15 rounds.

The variation pattern selection unit 235 selects the variation pattern of the special symbol displayed on the first special symbol display 221 or the second special symbol display 222 when the lottery result of the special symbol is “big hit”. Further, it is determined whether or not a reach effect is to be performed. The “reach effect” here is an effect performed by the image display unit 114 or the like for causing the player to expect a big hit.
The game progress control unit 236 controls the progress of the game in each game state.

When the normal symbol lottery is performed, the normal symbol control unit 237 determines whether the normal symbol lottery result is “winning or lost”. When it is determined as “winning”, the electric tulip 123 is opened for a specified time (for example, 6 seconds) and a specified number of times (for example, 3 times), and the winning probability of the game ball to the second start port 122 is increased. Generate a state. In addition, when it is determined as “disengagement”, such an open state of the electric tulip 123 is not generated. The probability that the normal symbol lottery result is won is set to 9/10.
In addition, the normal symbol control unit 237 sets the normal symbol fluctuation time to a long time, for example, 29 seconds, when the current operation state of the pachinko gaming machine 100 does not correspond to either the probability variation gaming state or the short-time gaming state. Set. On the other hand, when the current operating state of the pachinko gaming machine 100 corresponds to either the probability variation gaming state or the short-time gaming state, the variation time of the normal symbol variation is set to a short time, for example, 3 seconds.

The special winning opening operation control unit 238 controls the opening operation of the special winning opening 125.
The electric tulip operation control unit 239 controls the opening operation of the electric tulip 123.
The prize ball processing unit 240 controls the number of prizes received for various types of winnings and lotteries, and controls the payout of prize balls according to the prizes.
The output control unit 241 controls the output of control commands from the game control unit 200 to the effect control unit 300 and the payout control unit 400.
The random number control unit 242 controls updating of various random number values used in processing by the main control unit and the sub control unit.

  Next, the first start port detection unit, the second start port detection unit, the gate detection unit, the big winning port detection unit, and the normal winning port detection unit described above will be described in detail. These detection units are ball passage detection units that detect the passage of a game ball, and are switches (first start port switch 211, second start port switch 212, gate switch) that output signals according to the passage of the game ball, respectively. 214, a special winning opening switch 215, a normal winning opening switch 217), and a detection circuit provided in the game control unit 200 so as to be connected to the switches. Hereinafter, these sphere passage detection units are referred to as “sphere passage detection unit 500”, these switches are referred to as “sphere passage detection switch 510”, and these detection circuits are referred to as “sphere passage detection circuit 520”.

FIG. 5 is a diagram showing a schematic configuration of the ball passage detection unit 500, and FIG. 5A shows a view of the ball passage detection switch 510 in the direction in which the game ball passes and a ball passage detection circuit 520. (B) is an expanded sectional view of the VB-VB part of the ball passage detection switch 510 in (a).
As shown in FIG. 5, the ball passage detection switch 510 is arranged around a switch housing 511 having a passage hole 511a through which a game ball passes and a passage hole 511a inside the switch housing 511, and is not shown. And a detection coil 512 connected to the high-frequency oscillation circuit. The ball passage detection switch 510 has an input line 513 to which a driving voltage (for example, 12V) is supplied, and an output line 514 connected to the game control unit 200 via a connection line 522 to be described later. . The ball passage detection switch 510 generates a high frequency magnetic field from the detection coil 512 by the drive voltage supplied to the input line 513.
The ball passage detection circuit 520 has an NPN-type transistor 521, and 5 V is supplied to the base via a connection line 522 connected to the output line 514, and +5 V is applied to the collector of the transistor 521. In the state, it is connected to the input port 201a of the CPU 201 of the game control unit 200.

FIG. 6 is a diagram illustrating a state of signals on the connection line 522 and a state of signals supplied to the input port 201 a of the CPU 201.
In the ball passage detection unit 500 configured as described above, the magnetic loss of the high-frequency magnetic field generated from the detection coil 512 does not occur when the game ball does not pass through the passage hole 511a of the ball passage detection switch 510. When the game ball, which is a metal body, passes through the passage hole 511a, an induced current flows through the game ball and a magnetic loss occurs. Therefore, the ball passage detection switch 510 outputs an “H” level signal via the output line 514 when the game ball is not passing through the passage hole 511a, as shown in FIG. When the game ball passes through the passage hole 511 a, the impedance of the detection coil 512 changes and an “L” level signal is output via the output line 514.

In the ball passage detection circuit 520, as shown in FIG. 6B, the transistor 521 is turned on by an “H” level signal from the output line 514 in a normal time when the game ball does not pass through the passage hole 511a. Therefore, an “L” level signal is supplied to the input port 201 a of the CPU 201. On the other hand, when the game ball is passing through the passage hole 511a, the transistor 521 is not turned on by the “L” level signal from the output line 514, and the “H” level signal is supplied to the input port 201a. After the game ball is completely passed, the transistor 521 is turned on, so that an “L” level signal is supplied to the input port 201a.
The game control unit 200 recognizes that the game ball has passed to the ball passage detection unit 500 by receiving the “H” level signal from the ball passage detection circuit 520.

In this way, in the ball passage detection unit 500 configured as described above, a predetermined voltage is always applied to the detection coil 512 of the ball passage detection switch 510 during the period when power is supplied to the game board 110. As a result, adverse effects due to radio waves and noise are suppressed.
However, some players aim at the timing at which the game ball passes through the passage hole 511a of the ball passage detection switch 510, in other words, the timing at which the “H” level signal is supplied to the input port 201a of the CPU 201. There are those who generate illegal electromagnetic waves using devices that generate electromagnetic waves and perform illegal acts that illegally operate the ball passage detection unit 500 to illegally pay out game balls or draw lots. .

FIG. 7 is a diagram illustrating a state of a signal on the connection line 522 and a state of a signal supplied to the input port 201a of the CPU 201 when an illegal act is received.
When an improper electromagnetic wave is generated from the outside, the ball passage detection switch 510 is affected by the electromagnetic wave on the connection line 522, so that the game ball passes through the passage hole 511a as shown in FIG. The signal waveform having a cycle shorter than the ball passing time is switched to the “H” level. Therefore, an “L” level signal having a shorter cycle than that when the game ball normally passes through the passage hole 511 a is supplied to the ball passage detection circuit 520 of the game control unit 200. Then, the CPU 201 of the game control unit 200 receives an “H” level signal with a short cycle as shown in FIG. 7B from the ball passage detection circuit 520 due to the fraud. It is recognized that the ball passage detection switch 510 has detected the passage of a number of game balls according to the switching to the “H” level. As a result, an increase in illegal payout game balls or an increase in illegal lotteries occurs.

<First Embodiment>
Next, the fraud detection device 600 according to the first embodiment will be described.
The fraud detection device 600 according to the first embodiment is an example of an abnormal state recognition unit, and the above described fraudulent electromagnetic waves aiming at the timing when the game ball passes through the passage hole 511a of the ball passage detection switch 510 described above. Is a device that detects both a so-called “radio wave” fraudulent action and a so-called “dotsuki” fraudulent action that strikes the pachinko gaming machine 100.

FIG. 8A is a schematic configuration diagram of the fraud detection device 600 according to the first embodiment, and FIG. 8B is a cross-sectional view of a VIIIB-VIIIB portion in FIG.
The cheating detection device 600 partially includes a device having the same configuration and function as the above-described ball passage detection unit 500. That is, the fraud detection device 600 includes a ball passage detection switch 610 having the same configuration and function as the ball passage detection switch 510, and also includes a ball passage detection circuit 620 having the same configuration and function as the ball passage detection circuit 520. ing. The ball passage detection switch 610 is installed on the back side of the board surface 110 a of the game board 110, and the ball passage detection circuit 620 is configured in the game control unit 200. The ball passage detection switch 610 and the ball passage detection circuit 620 are an example of a detection unit that detects a metal body 632 described later.

  In addition, the cheating detection device 600 closes the opening for allowing the game ball to pass on both sides of the passage hole 611a of the ball passage detection switch 610 in the direction in which the game ball passes, and stores the game ball inside. An enclosing portion 631 as an example of a holding portion that forms a space that can be attached is attached. A metal body 632 that is a metal object is accommodated in a space formed by the inside of the surrounding portion 631 on both sides of the passage hole 611a and the passage hole 611a. The metal body 632 is an object that causes a magnetic loss of a high-frequency magnetic field generated from the detection coil 612 of the ball passage detection switch 610 and smoothly forms a space formed inside the surrounding portion 631 and the passage hole 611a. It can be exemplified that the object is a movable object, for example, a game ball itself that is actually used in a game.

  The fraud detection device 600 is arranged in the pachinko gaming machine 100 so that the direction in which the metal body 632 passes through the passage hole 611a is the horizontal direction. That is, it arrange | positions so that the direction shown in FIG. 8 may become an up-down direction. And the surrounding part 631 of the both sides of the passage hole 611a is the passage hole 611a from the outside, as shown in FIG.8 (b), when the pachinko gaming machine 100 in which this fraud detection device 600 is arranged is stationary. It inclines so that the opening part side may become a low position toward the opening part side. Thereby, when the pachinko gaming machine 100 is in a stationary state, the center of the metal body 632 remains in the passage hole 611a and causes a magnetic loss of the high-frequency magnetic field generated from the detection coil 612. In other words, when the pachinko gaming machine 100 is stationary, the surrounding portion 631 is formed so that the metal body 632 stays at a position where the magnetic loss of the high-frequency magnetic field generated from the detection coil 612 occurs. On the other hand, when the pachinko gaming machine 100 is shaken by an impact from the outside, the metal body 632 can smoothly move outward from the opening of the passage hole 611a and return to the original position again. 631 is molded. In other words, the metal body 632 is configured such that there is no step between the two so that the metal body 632 can be prevented from moving so that the metal body 632 can smoothly move between the passage hole 611a and the surrounding portion 631.

  In the fraud detection device 600 according to the present embodiment configured as described above, when the pachinko gaming machine 100 is stationary, the metal body 632 reduces the magnetic loss of the high-frequency magnetic field generated from the detection coil 612. The ball passing detection switch 610 outputs an “L” level signal in order to remain in the position to be generated. As a result, an “H” level signal is supplied to the input port 201 a of the CPU 201 via the ball passage detection circuit 620.

  On the other hand, in the case where an illegal act called “dotsuki” is performed in which the player hits the pachinko gaming machine 100 for the purpose of changing the course of the game ball or changing the winning timing, the metal body 632 is used. However, it moves in the direction away from the passage hole 611a from the position where the magnetic loss of the high-frequency magnetic field generated from the detection coil 612 occurs. Then, the metal body 632 does not cause a magnetic loss of the high-frequency magnetic field generated from the detection coil 612, and the ball passage detection switch 610 outputs an “H” level signal. Then, an “L” level signal is supplied to the input port 201 a of the CPU 201 via the ball passage detection circuit 620.

  In addition, when a fraudulent action called “radio wave goto” is performed in which a fraudulent electromagnetic wave is generated aiming at the timing when the game ball is passing through the passage hole 511a of the ball passage detection switch 510, the ball passage detection is performed. The switch 610 is affected by the electromagnetic wave and outputs an “H” level signal. Then, an “L” level signal is supplied to the input port 201 a of the CPU 201 via the ball passage detection circuit 620.

  When the CPU 201 of the game control unit 200 receives an “L” level signal via the ball passage detection circuit 620, an illegal act called “dotsuki” or an illegal act called “radio wave goto” is performed. Recognize that an action has taken place. When the gaming control unit 200 recognizes that the illegal act has been performed, the game control unit 200 transmits information indicating that the illegal act has been performed to the host computer via the board external information terminal board 250.

  As described above, the fraud detection device 600 can detect both an illegal act called “radio wave” and an illegal act called “dotsuki”. Therefore, reduce the number of parts compared to the case of having a dedicated device for detecting fraudulent behavior called “radio wave” and a dedicated device for detecting illegal behavior called “dotsuki”. Can do. In addition, the ball passage detection switch 610 and the ball passage detection circuit 620 that constitute a part of the fraud detection device 600 have the same configuration and function as the ball passage detection unit 500 that is used for general purposes and has established reliability. Therefore, it is highly reliable. Further, as the ball passage detection switch 610 and the ball passage detection circuit 620, by using the ball passage detection unit 500 which is an existing device, it can be designed more easily than newly designed. Furthermore, by using the game ball itself used for the game as the metal body 632, it is possible to suppress an increase in the types of parts and to design simply and early.

  In addition, in the fraud detection device 600 described above, both the fraudulent action called “radio wave” and the fraudulent action called “dotsuki” can be detected in the surrounding portion 631 as well. Although the shape of the surrounding portion 631 is determined so that the metal body 632 moves, the shape shown below may be used in the case where it is possible to detect only an illegal act called “radio wave”. That is, the surrounding portion 631 may have a shape that always keeps the metal body 632 at a position where the magnetic loss of the high-frequency magnetic field generated from the detection coil 612 of the ball passage detection switch 610 can be generated. A simple cap that closes both openings of the passage hole 611a of the ball passage detection switch 610 may be used. As a result, a fraudulent act called "radio wave" can be detected with high reliability with a simpler structure and a structure utilizing the ball passage detection unit 500 which is an existing device.

<Second Embodiment>
Next, a fraud detection apparatus 700 according to the second embodiment will be described.
Similarly to the fraud detection device 600 according to the first embodiment, the fraud detection device 700 according to the second embodiment is an example of an abnormal state recognition unit, and a fraudulent act called “radio wave goto” It is a device that detects both fraudulent actions called “dotsuki”.
FIG. 9A is a schematic configuration diagram of the fraud detection device 700 according to the second embodiment, and FIG. 9B is a cross-sectional view of the IXB-IXB portion in FIG.

  The cheating detection device 700 partially includes a device having the same configuration and function as the above-described ball passage detection unit 500. That is, the fraud detection device 700 has a ball passage detection switch 710 having the same configuration and function as the ball passage detection switch 510 and also has a ball passage detection circuit 720 having the same configuration and function as the ball passage detection circuit 520. ing. The ball passage detection switch 710 and the ball passage detection circuit 720 are an example of a detection unit that detects a metal body 732 described later.

  The fraud detection device 700 includes a metal body 732 that is a metal object, a holding member 733 as an example of a holding portion that holds the metal body 732, and a support shaft 734 that rotatably supports the holding member 733. And. The metal body 732, the holding member 733, and the support shaft 734 are arranged on the game board 110 such that the directions shown in FIG. In addition, when the pachinko gaming machine 100 is stationary, the metal body 732 is positioned at a position where the holding member 733 causes a magnetic loss of the high-frequency magnetic field generated from the detection coil 712, for example, the passage hole 711a of the ball passage detection switch 710. It is arranged so that its center of gravity is located inside. In other words, when the pachinko gaming machine 100 is in a stationary state, the metal body 732, the holding member 733, and the support shaft so that the metal body 732 stays at a position where magnetic loss of the high-frequency magnetic field generated from the detection coil 712 occurs. 734 is configured. Then, for example, when the pachinko gaming machine 100 is hit or dragged from the front side by a player, the holding member 733 rotates around the support shaft 734, and the metal body 732 is as shown in FIG. 9B. Shake back and forth. In addition, as the metal body 732, it can illustrate that it is the game ball itself actually used for a game, for example. As a mode for fixing the metal body 732 and the holding member 733, a hole is formed in the metal body 732, and a tip end portion of the holding member 733 is fitted into the hole, and the metal body 732 and the holding member 733 are bonded. A mode etc. can be illustrated.

  In the fraud detection device 700 according to the second embodiment configured as described above, the magnetic loss of the high-frequency magnetic field generated by the metal body 732 from the detection coil 712 when the pachinko gaming machine 100 is stationary. Therefore, the ball passage detection switch 710 outputs an “L” level signal. As a result, an “H” level signal is supplied to the input port 201 a of the CPU 201 via the ball passage detection circuit 720.

  On the other hand, when an illegal act called “dotsuki” is performed such as the pachinko gaming machine 100 being moved in the front-rear direction by the player, the metal body 732 is shaken in the front-rear direction, and the detection coil 712 is moved. It moves in the direction away from the passage hole 711a from the position where the magnetic loss of the high-frequency magnetic field generated from is generated. Then, the metal body 732 does not cause a magnetic loss of the high frequency magnetic field generated from the detection coil 712, and the ball passage detection switch 710 outputs an “H” level signal. Then, an “L” level signal is supplied to the input port 201 a of the CPU 201 via the ball passage detection circuit 720.

  In addition, when a fraudulent action called “radio wave goto” is performed in which a fraudulent electromagnetic wave is generated aiming at the timing at which a game ball is passing through the passage hole 711a of the ball passage detection switch 710, a ball passage detection is performed. The switch 710 is influenced by the electromagnetic wave and outputs an “H” level signal. Then, an “L” level signal is supplied to the input port 201 a of the CPU 201 via the ball passage detection circuit 720.

  When the CPU 201 of the game control unit 200 receives an “L” level signal via the ball passage detection circuit 720, a fraudulent act called “Dotsuki” or an illegal act called “Radio Goto” is performed. Recognize that an action is performed. When the gaming control unit 200 recognizes that the illegal act has been performed, the game control unit 200 transmits information indicating that the illegal act has been performed to the host computer via the board external information terminal board 250.

  As described above, the fraud detection device 700 can detect both a fraudulent action called “radio wave” and a fraudulent action called “dotsuki”. Therefore, reduce the number of parts compared to the case of having a dedicated device for detecting fraudulent behavior called “radio wave” and a dedicated device for detecting illegal behavior called “dotsuki”. Can do. Further, the ball passage detection switch 710 and the ball passage detection circuit 720 that constitute a part of the fraud detection device 700 have the same configuration and function as the ball passage detection unit 500 that is used for general purposes and has established reliability. Therefore, it is highly reliable. Further, as the ball passage detection switch 710 and the ball passage detection circuit 720, by using the ball passage detection unit 500 which is an existing device, it can be designed more simply and earlier than a new design. Furthermore, by using the game ball itself used in the game as the metal body 732, an increase in the types of components can be suppressed and the design can be performed easily and quickly.

  In addition, in the fraud detection device 700 described above, the metal body 732 is held so as to be able to detect both the so-called “radio wave” fraud and the so-called “dotsuki” fraud. Although the holding member 733 is rotatably supported with respect to the support shaft 734, the shape shown below may be used when only an illegal act called “radio wave goto” can be detected. That is, the holding member 733 that holds the metal body 732 may not be supported rotatably with respect to the support shaft 734. Further, the holding member 733 may be fixed to the rear surface of the game board 110 without providing the support shaft 734. As a result, a fraudulent act called "radio wave" can be detected with high reliability with a simpler structure and a structure utilizing the ball passage detection unit 500 which is an existing device.
