After this, the glass 23 is transparent having a transmittance of about 80% in the visible range, and the player visually recognizes that the game ball rolls through the front glass 22 and the rear glass 23 from the front. be able to.

  As shown in FIG. 3, a reed switch 51 is fixed behind the rear glass 23. As shown in FIG. 6, the reed switch 51 is configured by housing two leads 53 made of a ferromagnetic material in a glass tube 52. Nitrogen gas for preventing each activation is enclosed. Each of these two leads 53 is made of a cantilevered spring member, and a fixed end that is one end of each of the two leads 53 is fixed to the glass tube 52 and is the other end of each of the two leads 53. A contact portion 54 is fixed to the free end.

  As shown in FIG. 4, the reed switch 51 is overlapped behind the start port 26 so that the player cannot visually recognize the reed switch 51 from the front. The upper winning opening 39 and the lower winning opening 40 are each disposed outside the original detection area of the reed switch 51. As shown in FIG. 3, the reed switch 51 is arranged such that both leads 53 are parallel to the front surface of the front glass 22. In this state, a linear free state is obtained when the magnet is not pressed. In the respective free states of both leads 53, both contact portions 54 face each other through a gap, and the reed switch 51 is turned off. When a magnet is pressed against the front glass 22 from the front, the free ends of both leads 53 are magnetized to different polarities by the magnetic field from the rear glass 23. Then, both contact portions 54 contact each other by magnetic force against the elastic force of the lead 53, and the reed switch 51 is turned on.

  The reed switch 51 is connected to the main control circuit 27 via a switch circuit 55 as shown in FIG. The switch circuit 55 includes a resistor 56, two reference resistors 57, a resistor 58, a noise prevention capacitor 59, a comparator 60, and a transistor 61. When the reed switch 51 is in an OFF state, an output signal from the comparator 60 is output. The transistor 61 is turned off based on the low level, and the high level switch signal S is input to the main control circuit 27. When the reed switch 51 is switched from the off state to the on state, the transistor 61 is turned on based on the output signal from the comparator 60 becoming Hi level, and the Lo level switch signal S is input to the main control circuit 27. The The main control circuit 27 determines that the reed switch 51 is turned off in a state where the Hi level switch signal S is detected, and detects that the switch signal S has been switched from the Hi level to the Lo level. Based on this, it is determined that the reed switch 51 is turned on.

  As shown in FIG. 6, an illegal LED 62 is connected to the main control circuit 27. As shown in FIG. 1, the illegal LED 62 is fixed to the front frame 6 so as to be visually recognizable from the front, and when the main control circuit 27 determines that the reed switch 51 is turned off. The illegal LED 62 is turned off, and when it is determined that the reed switch 51 is turned on, the illegal LED 62 is turned on. The fraudulent LED 62 is equivalent to fraud notification means, and employees of pachinko halls identify that fraudulent acts using magnets have not been performed based on visual confirmation that the fraudulent LED 62 is not lit. It can be identified that an illegal act using a magnet is being performed based on visually confirming that the illegal LED 62 is lit.

According to the said Example 1, there exists the following effect.
The whole of the rear glass 23 including the fraud detection area E is made of magnetic glass, and the magnet is illegally brought close to any of the start opening 26, the upper winning opening 39 and the lower winning opening 40 through the window 21. Also, a magnetic field was applied from the rear glass 23 to each of the leads 53 of the reed switch 51. For this reason, since the reed switch 51 changes from the off state to the on state when the magnet is brought close to any of the start opening 26 to the lower winning opening 40, the illegal action of winning the game ball with the magnet at the start opening 26 and the above A common reed switch 51 can detect each of an illegal act of winning a prize in the winning opening 39 with a magnet and an illegal action of winning in the lower winning opening 40 with a magnet.

  The player improperly presses the magnet through the window 21 to the entrance 30 of the warp route 29 while firing the game ball into the game area 24 of the game board 16, and illegally places the game ball into the entrance 30 of the warp route 29. There is a person who conducts illegal acts to enter. Even when a magnet is improperly pressed to the entrance 30 of the warp route 29 through the window 21 from the front, a magnetic field is applied from the rear glass 23 to each of the leads 53 of the reed switch 51, and the reed switch 51 is turned off. Since the state changes from the on state to the on state, an illegal act of winning a game ball with the magnet at the entrance 30 of the warp route 29 can be detected by the reed switch 51 common to each of the start opening 26 to the lower winning opening 40.

  Since the rear glass 23 of the window 21 is made of magnetic glass, the rear glass 23 is magnetized by the magnetic field from the magnet when the magnet is pressed into the game area 23 of the game board 16 through the window 21 from the front. . For this reason, when the magnet is moved along the front surface of the window 21, resistance is given to the moving operation of the magnet by the magnetic force from the rear glass 23, so that a large force exceeding the resistance force from the rear glass 23 is required. Become. Therefore, since the magnet cannot be moved and operated to the start opening 26, the top winning opening 39, and the lower winning opening 40 in a state where the game balls are attracted to the pachinko hall clerk at a speed that cannot be found, It becomes difficult to perform an illegal act of winning each of the starting opening 26 to the lower winning opening 40 using a magnet.

In the first embodiment, the entire front glass 22 may be made of magnetic glass.
In the first embodiment, the rear glass 23 and one lead 53 of the reed switch 51 are connected in contact with each other through a ferromagnetic connecting member, and each of the leads 53 is connected from the rear glass 23 through the connecting member. A magnetic field may be applied. In the case of this configuration, since the reed switch 51 can be disposed in a region that does not face the window 21 from the rear, the degree of freedom of the reed switch 51 is improved.

  As shown in FIG. 7, a window 71 is fixed to the front frame 6 in place of the window 21. This window 71 is constituted by joining a front glass 72 and a rear glass 73 to each other through a gap, and the front glass 72 is entirely composed of an inorganic transparent nonmagnetic glass. The non-magnetic glass 74 and the magnetic glass 75 are joined together. This magnetic glass 75 is transparent and contains terbium oxide, and constitutes only the fraud detection region E of the rear glass 73. The nonmagnetic glass 74 is transparent and made of an inorganic material, and constitutes the remaining part of the fraud detection area E in the rear glass 73.

According to the said Example 2, there exist the following effects.
Only the fraud detection area E of the rear glass 73 is composed of the magnetic glass 75. For this reason, the magnetic field applied to each of the leads 53 of the reed switch 51 from the rear glass 73 becomes stronger because the detection area of the magnet is narrower than when the entire rear glass 73 is made of magnetic glass. The magnet can be detected even when is used. In addition, when the magnet is moved along the front surface of the window 71, resistance is applied to the moving operation of the magnet within the fraud detection region E by the magnetic force from the magnetic glass 75, so that the resistance from the magnetic glass 75 is exceeded. Great power is required. For this reason, since it becomes impossible to move and operate the magnet toward the start opening 26, the top winning opening 39, and the lower winning opening 40 at a speed that cannot be found by the pachinko hall clerk in the adsorbed state of the game balls, It is difficult to perform a fraudulent act in which each of the starting opening 26 to the lower winning opening 40 is won using a magnet.

In the second embodiment, only the fraud detection area E of the front glass 72 may be made of magnetic glass.
In the second embodiment, the magnetic glass 75 and one lead 53 of the reed switch 51 are connected in contact with each other through a ferromagnetic connecting member, and each of the leads 53 is connected from the magnetic glass 75 through the connecting member. A magnetic field may be applied. In the case of this configuration, the reed switch 51 can be disposed in a region that does not face the magnetic glass 75 from the rear, so that the degree of freedom of the reed switch 51 is improved.

  As shown in FIG. 8, a window 81 is fixed to the front frame 6 in place of the window 21. This window 81 is constituted by joining the front glass 82, the rear glass 83, and the intermediate film 84 to each other by using a nonmagnetic transparent adhesive, and the front glass 82, the rear glass 83, and the intermediate film 84. Each is set to the same rectangular shape. Each of the front glass 82 and the rear glass 83 is made of a transparent magnetic glass, and the rear glass 83 is disposed behind the front glass 82 so as to overlap the front glass 82. The intermediate film 84 is made of a nonmagnetic transparent synthetic resin. The intermediate film 84 is disposed between the front glass 82 and the rear glass 83 so as to overlap each of the front glass 82 and the rear glass 83. The rear surface of the front glass 82 and the front surface of the rear glass 83 are intermediate films. 84 is in close contact with the bonding force of the adhesive.

  As shown in FIG. 8, an antenna pattern 85 is formed on the front surface of the intermediate film 84, and the antenna pattern 85 is in close contact with the rear surface of the front glass 82 by the bonding force of the adhesive. This antenna pattern 85 is obtained by joining a wire made of a ferromagnetic material to the intermediate film 84 in a predetermined pattern, and the wire diameter of the wire becomes a value that a player cannot recognize the antenna pattern 85 with the naked eye. It is set. The antenna pattern 85 is magnetized by a magnetic field from the magnet when the magnet is improperly pressed against the front glass 82 from the front, and is stretched over the entire area including the fraud detection area E of the intermediate film 84.

According to the said Example 3, there exist the following effects.
The antenna pattern 85 is formed over the entire area including the fraud detection area E of the window 81, and the magnet is illegally disposed at any of the start opening 26, the entrance 30 of the warp route 29, the upper winning opening 39, and the lower winning opening 40 through the window 81. Even when approached, magnetic fields were applied to both leads 53 of the reed switch 51 from the front glass 82, the rear glass 83, and the antenna pattern 85, respectively. For this reason, the reed switch 51 changes from the off state to the on state when the magnet is brought close to any of the starting opening 26 to the lower winning opening 40. The common reed switch 51 can detect each of an illegal act of winning a prize at the entrance 30 of the route 29 with a magnet, an illegal action winning a prize at the top prize opening 39 with a magnet, and an illegal action winning a prize at the bottom prize opening 40 with a magnet. . Moreover, when the magnet is moved along the front surface of the window 81, resistance is given to the moving operation of the magnet by the magnetic force from each of the front glass 82, the rear glass 83, and the antenna pattern 85. A large force exceeding the resistance force from the pattern 85 is required. Therefore, since the magnet cannot be moved and operated to the start opening 26, the top winning opening 39, and the lower winning opening 40 in a state where the game balls are attracted to the pachinko hall clerk at a speed that cannot be found, It becomes difficult to perform an illegal act of winning each of the starting opening 26 to the lower winning opening 40 using a magnet.

  In the third embodiment, both the front glass 82 and the rear glass 83 are made of nonmagnetic glass, and the antenna pattern 85 and one lead 53 of the reed switch 51 are in contact with each other via a ferromagnetic connecting member. The magnetic field may be applied to each of the leads 53 from the antenna pattern 85 through the connection member. In the case of this configuration, since the reed switch 51 can be disposed in a region that does not face the window 81 from the rear, the degree of freedom of the reed switch 51 is improved.

  In the third embodiment, the antenna pattern 85 may be formed on the rear surface of the intermediate film 84 and the front surface of the rear glass 83 may be adhered to the antenna pattern 85.

  As shown in FIG. 9, an antenna pattern 86 is formed on the intermediate film 84 of the window 81 so as to be located only in the fraud detection region E. The antenna pattern 86 is formed by joining a ferromagnetic wire to the front surface of the intermediate film 84 in a predetermined pattern, and the wire diameter of the wire cannot be recognized by the player with the naked eye. Is set to a value.

According to the said Example 4, there exists the following effect.
An antenna pattern 86 is formed only in the fraud detection area E of the window 81. Therefore, the magnetic field applied to each of the leads 53 of the reed switch 51 from the antenna pattern 86 becomes stronger, although the detection area of the magnet is narrower than when the antenna pattern 86 is formed on the entire window 81. The magnet can be detected even when is used. In addition, when the magnet is operated to move along the front surface of the window 81, resistance is applied to the magnet moving operation within the fraud detection area E by the magnetic force from the antenna pattern 86, so that the resistance from the antenna pattern 86 is exceeded. Great power is required. For this reason, since it becomes impossible to move and operate the magnet toward the start opening 26, the top winning opening 39, and the lower winning opening 40 at a speed that cannot be found by the pachinko hall clerk in the adsorbed state of the game balls, It is difficult to perform a fraudulent act in which each of the starting opening 26 to the lower winning opening 40 is won using a magnet.

In each of the above Examples 3 to 4, one of the front glass 82 and the rear glass 83 may be made of magnetic glass, and the other may be made of nonmagnetic glass.
In the fourth embodiment, both the front glass 82 and the rear glass 83 are made of nonmagnetic glass, and the antenna pattern 86 and one lead 53 of the reed switch 51 are in contact with each other via a ferromagnetic connecting member. It is good also as a structure which connects in a state and applies a magnetic field to each of both the lead | read | reeds 53 through a connection member from the antenna pattern 86. FIG. In the case of this configuration, since the reed switch 51 can be disposed in a region that does not face the fraud detection region E of the window 81 from the rear, the degree of freedom of the reed switch 51 is improved.

In the fourth embodiment, the antenna pattern 86 may be formed on the rear surface of the intermediate film 84, and the front surface of the rear glass 83 may be adhered to the antenna pattern 86.
In each of the first to fourth embodiments, a Hall element magnetic sensor or a magnetoresistive element sensor may be used instead of the reed switch 51.
