  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. It is arranged in the detection area. 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, and each of the reeds 53 starts on the front glass 22. In a state where no magnet is pressed from the front of the mouth 26, a linear free state is obtained. 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 of the start port 26, the free ends of both leads 53 are magnetized to different polarities by the magnetic field from the front glass 22. 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.
Since the front glass 22 of the window 21 is made of magnetic glass, the front glass 22 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 front glass 22, so a large force exceeding the resistance from the front glass 22 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 rear glass 23 may be made of magnetic glass.

  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 via a gap, and the rear glass 73 is entirely made 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 target area E of the front glass 72. The nonmagnetic glass 74 is transparent and made of an inorganic material, and constitutes the remaining portion of the fraud target area E in the front glass 72. The fraud target area E is an area in front of the start opening 26, an area in front of the left upper prize opening 39, an area in front of the left lower prize opening 40, and an area in front of the right upper prize opening 39. Each of the regions in front of the right lower prize opening 40 and the magnetic glass 75 is formed from the magnet based on the fact that the magnet is improperly pressed against the fraud target region E from the front. Magnetized by a magnetic field.

According to the said Example 2, there exist the following effects.
Only the fraudulent target area E of the window 71 is composed of the magnetic glass 75. For this reason, 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 target area E by the magnetic force from the magnetic glass 75. Greater power 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 second embodiment, only the fraud target area E of the rear glass 73 may be made of magnetic glass.
In each of the first and second embodiments, a Hall element magnetic sensor or a magnetoresistive element sensor may be used instead of the reed switch 51.
