Can be done.

The apex of the bulging surface 80A of the obstacle nail 80 is abutted with a slight gap from the light transmitting plate 12. Further, like the protruding wall 14W of the starting winning opening 14 and the protruding wall 24 of the display window 13W, between the protruding wall and the translucent plate 12 that regulate the flow direction and area of the game ball as in the case of the obstacle nail 80. The gap is also about the same as the gap between the obstacle nail 80 and the translucent plate 12. A groove member made of an elastomer (not shown) is fitted to the tip of the boundary protrusion wall 15 to be in close contact with the light transmitting plate 12, and an illegal act of inserting a wire or the like into the game area R1 is prevented.

As shown in FIG. 1, the plurality of obstacle nails 80 are located slightly above the starting winning opening 14, the normal winning opening 20, etc., and are arranged side by side with an interval of one game ball. Some are so-called life nails, and some are arranged next to each other in a row to guide the game ball. There is also an obstacle nail 80 that is located in the vicinity of the boundary protrusion 15 and the protrusion 24 and regulates the flow direction of the game ball in cooperation with the boundary protrusion 15 and the like.

By the way, if the obstacle nail 80 is adjacent to the protruding wall 24 or the like, the work of adjusting the nail may be difficult. Specifically, when the obstacle nail 80 is adjacent to the protruding wall 24 or the like, the hammer used for adjusting the nail or the dedicated pin having a bifurcated tip cannot be brought into contact with the obstacle nail 80 or is brought into contact with the obstacle nail 80. The angle may become smaller with respect to the axial direction of the obstacle nail 80, making the work difficult.

On the other hand, in the game machine 10 of the present embodiment, among the plurality of obstacle nails 80, for example, it is considered that the winning of the warp gutter 27 is relatively large, and the protrusion 24 or the boundary protrusion 15 is affected. The first to third recesses 31, 32, 33 are provided in the protrusion 24 or the boundary protrusion 15 so that the nails of the adjacent first to third obstacle nails 81, 82, 83 can be easily adjusted. It is formed.

Specifically, as shown in FIG. 3, the portion of the protruding wall 24 located above the warp gutter 27 has a rib structure, and the lower portion of the protruding wall 24 is bent in a mountain shape toward the left side. It is part 24A. Then, the first obstacle nail 81 is arranged at a position adjacent to the apex portion of the protrusion wall 24. Further, one hypotenuse 24B of the bent portion 24A extends diagonally upward from the introduction port 27A of the warp gutter 27, and a row of nails extending diagonally in the vertical direction with a space of one game ball from the one hypotenuse 24B. 85 is facing from below. The nail row 85 is in a toothless state. Then, the second obstacle nail 82 is arranged at the upper end of the nail row 85 and at a position adjacent to the boundary protrusion wall 15. Further, above the first and second obstacle nails 81 and 82, nail rows 84 are lined up so as to bisect the strip-shaped flow-down region between the protrusion 24 and the boundary protrusion 15 in the width direction. .. The nail row 84 is in a toothless state, and three third obstacle nails 83 are arranged in a row adjacent to each other so as to form an intermediate portion thereof.

The first recess 31 is formed by cutting out a part of the tip surface of the protrusion 24 at the apex of the bent portion 24A adjacent to the first obstacle nail 81. Further, the second recess 32 is formed by cutting out a part of the tip surface of the boundary protrusion wall 15 adjacent to the second obstacle nail 82. Further, the third recess 33 is formed by cutting out a part of the tip surface of the protrusion 24 at a portion of the protrusion 24 facing the third obstacle nail 83. Further, the above-mentioned elastomer groove member of the boundary protrusion 15 is divided in the second recess 32. When the game ball is guided to the ball advance entrance 15A, an elastomer groove member may be attached to the protruding wall 15B so as to face the divided portion from the side.

Specifically, the diameter of the game ball is 11 [mm], the distance between the translucent plate 12 and the game plate 11 is 19.2 [mm], and the distance from the front surface of the game plate 11 to the apex of the obstacle nail 80 is. It is 18 [mm]. The amount of protrusion of the nail body 80H from the game plate 11 is 17 [mm], the height of the head portion 80C is 1 [mm], the diameter of the nail body 80H is 1.85 [mm], and the diameter of the head portion 80C is. It is 4.34 [mm]. Further, since the nail adjustment work is mainly performed by hitting the head portion 80C with a hammer or a pin, there are many opinions of workers who preferably have a space of 1 [mm] or more around the head portion 80C. Further, it is preferable that the head portion 80C does not interfere with the protrusion 24 or the like when the obstacle nail 80 is tilted toward the protrusion 24. Further, it is preferable that the game ball does not come into contact with the edge of the recess. In consideration of these, the distances between the bottom surfaces of the first to third recesses 31 to 33 and the translucent plate 12 are 3 [mm] or more and less than 5.5 [mm]. ..

Further, when the first obstacle nail 81 is formed at a position closer than the radius of the game ball as in the first recess 31, the end of the opening width of the first recess 31 is the obstacle nail 80. The game ball does not come into contact with the edge of the first recess 31 unless it is separated from the nail body 80H of the obstacle nail 80 by 5.5 [mm] or more, but 5.5 [mm] from the nail body 80H of the obstacle nail 80. If the distance is greater than or equal to the distance, the game ball may come into contact with the edge of the first recess 31 if the distance from the translucent plate 12 to the bottom surface of the first recess 31 is equal to or greater than the radius of the game ball. On the other hand, as described above, it is preferable that there is a space of 1 [mm] or more around the head portion 80C. From these, it can be said that it is preferable that there is a space around the nail body 80H at a distance of 2.3 [mm] or more and less than 5.5 [mm] from the nail body 80H. In view of this, the inner surfaces of the first to third recesses 31, 32, 33 are extended to the first to third obstacle nails 81, 82, 83, and the first to third obstacle nails 81. , 82, 83 have the shortest distance from the nail body 80H of 2.3 [mm] or more and less than 5.5 [mm].

This concludes the description of the configuration of the gaming machine 10 of the present embodiment. According to the configuration of the game machine 10, the protrusions 24 and the boundary protrusions 15 adjacent to the first to third obstacle nails 81 to 83 are provided with the first to third recesses 31 to 33. The work of adjusting the nails of the first to third obstacle nails 81 to 83 can be easily performed. Specifically, by providing the first to third recesses 31 to 33, the tool for adjusting the nail is received so that at least a part thereof is received by the first to third recesses 31 to 33. It can be used by laying it down in the axial direction of the first to third obstacle nails 81 to 83. As a result, the force is easily transmitted to the first to third obstacle nails 81 to 83, and the nail adjustment work becomes easy. Further, when the first and second obstacle nails 81 and 82 are tilted toward the protruding wall 24 and the boundary protruding wall 15 to adjust the nail, the head portion 80C is received in the first and second recesses 31 and 32. Until then, the first and second obstacle nails 81 and 82 can be deformed, and in this respect as well, the nail adjustment work becomes easy.

Further, in order to easily perform the work of adjusting the nails of the first to third obstacle nails 81 to 83, it is conceivable to make the entire protrusion wall 24 and the entire boundary protrusion wall 15 lower than the obstacle nail 80. By forming the first to third recesses 31 to 33 in a part of the protruding wall 24 and the boundary protruding wall 15 as in the present embodiment, it is possible to suppress a decrease in the strength of the protruding wall 24 and the boundary protruding wall 15. it can. Further, since the distance between the bottom surface of the first to third recesses 31 to 33 and the light transmitting plate 12 is less than the radius of the game ball, the guidance of the game ball by the boundary protrusion wall 15 and the protrusion wall 24 is stable. .. Further, since the first to third recesses 31 to 33 penetrate the protruding wall 24 and the boundary protruding wall 15 in the wall thickness direction, the tool can be easily lateral to the first to third obstacle nails 81 to 83.
