A waiting passage 41 for waiting in the game board, a ball payout device 42 for paying out a prize ball based on a winning state on the game board 5, and a ball payout passage for discharging a prize ball discharged from the ball payout device 42 to the ball tray 31. 43, etc. are equipped with various circuit boards such as a power supply board 44 and a game control board 45, electronic parts, and the like.

  Next, the illegal device intrusion prevention member of the pachinko gaming machine according to the embodiment of the present invention will be described in detail with reference mainly to FIGS. Here, FIG. 4 is a rear view showing the first unauthorized intrusion prevention member attached to the glass door in the pachinko gaming machine according to the embodiment of the present invention, and FIG. 5 shows the first unauthorized intrusion prevention member. FIG. 6 is a front view showing a second unauthorized intrusion prevention member mounted on the game auxiliary board, and FIG. 7 is a plan view showing the second unauthorized intrusion prevention member.

  First, the first unauthorized intrusion preventing member 23 will be described mainly with reference to FIGS. 4 and 5.

  The first unauthorized tool intrusion prevention member 23 includes a flat plate portion 55 formed along the back surface of the glass door 16 and a rear extension portion 56 extending rearward from the outer side portion and the lower end portion of the flat plate portion 55. It is configured. The flat plate portion 55 has a shape that matches the shape of the lower corner portion 22 that is the mounting position, and is connected to the lower frame fitting 18 at the lower corner portion 22 and the right frame fitting 20 in the rear view. Two mounting holes 57 are formed corresponding to the fixed positions. Further, the rearward extending portion 56 has a shape bent along each inner surface of the right end portion of the lower frame metal fitting 18 and the lower end portion of the right frame metal fitting 20, and extends along the back surface of the peripheral wall 46 of the glass door 16. It is formed as follows. And the clearance gap produced in the lower side corner | angular part 22 can be obstruct | occluded by mounting | wearing the lower side corner | angular part 22 of the back side of the glass door 16 with the 1st unauthorized tool penetration | invasion prevention member 23. FIG.

  That is, an illegal tool intrusion path through which an illegal tool such as a wire or a piano wire enters the gaming machine through a gap generated in the lower corner portion 22 of the glass door 16 is surely provided by the first illegal tool intrusion prevention member 23. Can be blocked. Therefore, by entering an unauthorized tool through this gap, the winning detection switch 12 is operated to open the start winning port 10, or the specific area passage detection switch 13 is operated to open the special winning port 11. Thus, an illegal act of illegally acquiring a prize ball can be prevented.

  Next, the foul ball collection member 30 that also functions as the second unauthorized intrusion prevention member as described above will be described mainly with reference to FIGS. 6 and 7.

  The foul ball collection member 30 is connected to an upper portion of the launch rail portion 29 of the hit ball launching device 25, and a launch rail portion 61 that guides the game balls launched from the hit ball launch device 25 together with the launch rail portion 29 to the game area 7. There are provided a first foul ball collection port 62 and a second foul ball collection port 63 formed on the left and right sides, respectively, in the front view of the firing rail portion 61. The firing rail portion 61 is opened at the front side to form a groove shape, and extends obliquely upward on the left side of the front surface. The upper end portion of the rear surface 64 is locked to a locking convex portion 65 formed on the front frame 2 side. A possible locking recess 66 is formed. Further, a first front protrusion 68 protruding forward is formed on the front end surface of the side wall 67 of the firing rail portion 61 on the first foul ball collection port 62 side (that is, the hinge portion 17b side). The part 68 can come into contact with the lower part 50 of the rear surface of the opposing engaging part 47. A fitting portion 69 into which the firing rail portion 29 of the ball striking device 25 can be fitted is formed below the firing rail portion 61. Further, an attachment hole 73 is formed below the first foul ball collection port 62, and the foul ball collection member 30 is fixed to the front frame 2 by inserting a fixing tool such as a screw into the attachment hole 73. It has become so.

  The first foul ball collection port 62 and the second foul ball collection port 63 are each formed so as to be inclined downward and the upper portions 70 and 71 project forward, and the upper portion of the first foul ball collection port 62 A second front projecting portion 72 is formed on the front end surface of 70 so as to project further forward. The front end surface of the upper portion 70 of the first foul collection port 62 is stepped so as to be aligned with the stepped portion 49 of the opposing engaging portion 47, and the second front protruding portion 72 is the engaging portion 47. It can come into contact with the upper portion 51 on the back surface.

  In this way, the first front protrusion 68 abuts on the lower portion 50 on the back of the engaging portion 47 facing, and the second front protrusion 72 abuts on the upper portion 51 on the back of the engaging portion 47 facing. Therefore, from the gap formed between the glass door 16 around the hinge portion 17b and the ball tray 31, via the upper portion of the step portion 49 of the engaging portion 47 of the ball tray 31, a wire or The illegal tool intrusion path through which an illegal tool such as a piano wire enters can be surely blocked by the second illegal tool intrusion prevention member. Therefore, by entering an unauthorized tool through this gap, the winning detection switch 12 is operated to open the start winning port 10, or the specific area passage detection switch 13 is operated to open the special winning port 11. Thus, an illegal act of illegally acquiring a prize ball can be prevented.

  In addition, the shape of the 1st fraudulent tool intrusion prevention member 23 and the 2nd fraudulent tool intrusion prevention member (foul ball collection member 30) is not limited to the shape demonstrated in the said embodiment, Various changes are possible. Is possible.

  In the above embodiment, the case where the present invention is applied to a pachinko gaming machine has been described. However, this is merely an example, and the present invention can be applied to a ball game machine other than a pachinko gaming machine. Needless to say, there is.
