  The attacker device 183 is determined by the main control device 10 when the lottery result relating to the big hit game that is performed in response to the winning of the game ball to the first start winning port 155 or the second starting winning port 162 is a win. Based on the type of jackpot (number of rounds), a round process for opening the big winning opening 182 is executed, so that more game balls than the normal game can win the big winning opening 182. This provides a big hit game (advantageous game).

(Magnetic detection sensor)
As shown in FIGS. 8, 10, and 11, the first magnetic detection sensor 189 a is large between the first start winning award 155 and the solenoid 186 on the rear surface of the base body 181 and the first starting winning award 155. It is provided so as to be fixed by the first sensor holder 189b between the winning opening 182. The first magnetic detection sensor 189a is a magnet that approaches from the front in the first predetermined range of the upper region including the first start winning opening 155 and the big winning opening 182 of the base body 181 (winning opening unit 180) and the vicinity thereof. Can be detected.

  The first sensor holder 189b is fixed to the base body 181 with a screw, and has a substantially box shape that can accommodate the first magnetic detection sensor 189a that opens rearward. Further, the first sensor holder 189b is provided at its rear part with an elastically deformable claw portion N for fixing (engaging) the accommodated first magnetic detection sensor 189a so as not to be detached rearward. When attaching the first magnetic detection sensor 189 a to the base body 181, the first magnetic detection sensor 189 a can be fixed by being pushed in from behind the first sensor holder 189 b and engaging with the claw portion N. Therefore, for example, even when it is necessary to replace the first magnetic detection sensor 189a due to a malfunction, the first magnetic detection sensor 189a can be easily removed by elastically deforming the claw portion N in the non-engagement direction. Since it is only necessary to push the new first magnetic detection sensor 189a from the rear side of the first sensor holder 189b and engage with the claw portion N, it is possible to attach (replace) easily and reliably without requiring a tool. it can.

  Similarly, the second magnetic detection sensor 189c is provided on the rear surface of the base body 181 so as to be fixed by the second sensor holder 189d on the lower left side of the special winning opening 182 and to the left of the out opening frame 178a. The second magnetic detection sensor 189c can detect magnetism approaching from the front in the second predetermined range of the lower region including the large winning port 182 and the out port 178 of the base body 181 (winning port unit 180) and the vicinity thereof. And

  The second sensor holder 189d is fixed to the base body 181 with a screw, and has a substantially box shape capable of accommodating the second magnetic detection sensor 189c that opens rearward. Further, the second sensor holder 189d is provided with an elastically deformable claw portion N for fixing (engaging) the accommodated second magnetic detection sensor 189c so as not to be detached rearward at the rear portion thereof. When attaching the second magnetic detection sensor 189c to the base body 181, the second magnetic detection sensor 189c can be fixed by being pushed in from behind the second sensor holder 189d and engaged with the claw portion N. Therefore, for example, even when the replacement is necessary due to the malfunction of the second magnetic detection sensor 189c, the second magnetic detection sensor 189c can be easily removed by elastically deforming the claw portion N in the non-engagement direction. It is only necessary to push the new second magnetic detection sensor 189c from the rear side of the second sensor holder 189d and engage with the claw portion N, so that it can be easily and reliably attached (replaced) without requiring a tool. it can.

  In the gaming machine of the present embodiment, when the first and second magnetic detection sensors 189a and 189c detect magnetism, a detection signal is transmitted to the sub-control device 20, and the sub-control device 20 is based on the detection signal. It is notified by sound, lighting, display exercises, etc. that fraudulent activity has been or is likely to be made through a production device such as the speaker 8, illumination device, and production display device 175 described later.

(Disposition relationship of solenoid, first magnetic detection sensor, second magnetic detection sensor, etc.)
The range of the magnetic field generated by the solenoid 186, the detection ranges of the first and second magnetic detection sensors 189a and 189c, their arrangement, and the like will be described.
The first magnetic detection sensor 189a is disposed at a position where the detection range (first predetermined range) and the magnetic field range of the solenoid 186 overlap. Therefore, the mounting / cover member 188a and the cover member 188b are disposed so as to be interposed between the solenoid 186 and the first magnetic detection sensor 189a. Specifically, an attachment / cover member 188a and a cover member 188b are provided on the upper portion and the left and right portions of the solenoid 186 (see FIGS. 8 and 9). Thereby, the magnetic field (magnetism) of the solenoid 186 is not affected by the first magnetic detection sensor 189a located at the upper left of the solenoid 186.

  On the other hand, the second magnetic detection sensor 189c is arranged so that its detection range (second predetermined range) and the magnetic field range of the solenoid 186 do not overlap. Specifically, the solenoid 186 is separated from the second magnetic detection sensor 189c by a predetermined distance t in the left-right and front-back directions (predetermined range). Accordingly, the solenoid 186 may not be provided with a similar cover member such as the mounting / cover member 188a or the cover member 188b. Note that the predetermined distance t at which the above range does not overlap is not limited as long as the distance can be secured. That is, it is only necessary to ensure the predetermined distance t only in the front-rear direction, the left-right direction, the up-down direction, or a combination thereof.

  As described above, by providing the mounting and cover member 188a or the cover member 188b around the solenoid 186, the magnetic detection sensor 189a and 189b are not affected by the magnetic field of the solenoid 186. Since other components can be arranged without considering the arrangement of 189a and 189b, the degree of freedom in design can be improved.

(Flow until detecting and reporting fraud using a magnet)
In order for a fraudster who performs cheating to illegally win a game ball, for example, in order to clog a game ball rolling in the game area 101 in the vicinity of the first start winning opening 155, a glass door When the magnet approaches the vicinity of the first start winning opening 155 from the front surface of No. 4, the first magnetic detection sensor 189a detects the magnetism of the magnet and transmits a detection signal to the sub-control device 20 based on the detection.

  In addition, when a fraudster attempts to block a game ball that rolls in the game area 101 in the vicinity of the out port 178, when the magnet approaches the vicinity of the out port 178 from the front of the glass door 4, The 2 magnetism detection sensor 189c detects the magnetism of the magnet, and transmits a detection signal to the sub-control device 20 based on the detection. Based on the detection signal, the sub-control device 20 uses a sound, illumination, a message indicating that a fraudulent act has been or may have been performed through a production device such as the speaker 8, an illumination device, and a production display device 175 described later. Notify by display exercises.

  As described above, the winning opening unit 180 is assembled into the base body 181 by previously assembling unit members 180a including the first starting winning port 155, the large winning port 182, the attacker device 183, the out port frame 178a, the ground wire 190, and the like. be able to. That is, for example, if an illegal act using a magnet is performed, a place where it is assumed that an illegal winning of a game ball can be performed is indicated by the first and second magnetic detection sensors 189a, Since it can be unitized in a state set in advance so as to be within the effective detection range related to magnetism of 189b, the accuracy of detection of fraudulent acts of the first and second magnetic detection sensors 189a and 189b as the prize opening unit 180 As a result, the detection performance can be stabilized.

  More specifically, by arranging the second magnetic detection sensor 189c around the out port 178 through which many game balls pass, in other words, a plurality of game balls can be easily formed in a so-called saddle state, It is possible to prevent the illegal winning that directly causes damage by preventing the achievement and easily arranging the first magnetic detection sensor 189a around the first start winning opening 155 and the large winning opening 182. it can.

  In addition, by unitizing the prize opening unit 180, it can be diverted to other (different types) gaming machines while maintaining its detection accuracy. By making it possible to divert the prize opening unit 180, it is not necessary to make adjustments at the time of assembling in other gaming machines, and it is possible to reduce the assembling man-hours and to newly relate to the arrangement of magnetic detection sensors, etc. Design and development time can be shortened or omitted. Furthermore, since the prize opening unit 180 is unitized, it can be arranged in units with respect to the game board 100, so that it does not depend on the installation environment, and is provided at an optimal place on the game board based on game characteristics and the like. Is possible.

  In addition, since the first magnetic detection sensor 189a is not affected by the magnetic field by blocking the magnetic field generated by the solenoid 186 by the mounting and cover member 188a and the cover member (magnetic prevention unit) 188b, the magnetic detection accuracy is improved. Can be improved.
