A flange portion 24b extending upward is formed at the front end portion of the upper frame member 24 to increase the rigidity of the upper frame member 24. Further, the flange portion 24b is configured to abut against the front end surface of the outer frame 11 when the middle frame 12 is closed, so as to prevent illegal acts due to foreign matter insertion between the middle frame 12 and the outer frame 11. It has become.

  Next, the relationship between the ball tank 43 and the tank rail 45 will be described. As shown in FIG. 4 or FIG. 5, the ball tank 43 includes a tank bottom surface 43a inclined downward from the right frame member 27 side toward the left frame member 26 side, and upward along the outer peripheral edge of the tank bottom surface 43a. It is formed in a substantially rectangular box shape that opens upward from the rising side wall 43b, and pachinko balls are stored in a storage space 44 defined by the tank bottom 43a and the side wall 43b. The tank rail 45 is provided on the inclined lower end side of the ball tank 43 (tank bottom surface 43a), and the communication port 43c formed in the side wall portion 43b on the left frame member 26 side (tank rail 45 side) of the ball tank 43. The tank rail 45 is configured to communicate with the storage space 44 via the. In addition, the side wall 43b on the left frame member 26 side (tank rail 45 side) of the ball tank 43 has a ball guidance as a ball guidance means for guiding a pachinko ball to the communication port 43c on the surface facing the storage space 44. A surface 43d is formed. Here, the ball guide surface 43d is formed in a concave shape (see FIG. 5), and the communication port absorbs the ball pressure of the pachinko sphere flowing down to the ball guide surface 43d along the tank bottom surface 43a of the ball tank 43. 43c can be promptly guided.

  On the other hand, as shown in FIG. 5 or 6, the tank rail 45 is connected to the communication port 43 c of the ball tank 43 and extends in a direction along the longitudinal direction of the ball tank 43. And a second spherical path portion 47 connected to the end of the first spherical path portion 46 so as to be folded back in the opposite direction. Here, each of the first and second ball path portions 46 and 47 has a passage width set to be substantially the same as the diameter of the pachinko ball, and the pachinko balls coming from the communication port 43c flow down in a line. To get. The rail bottom surface 46 a in the first ball path portion 46 is set to be inclined substantially equal to the inclination angle of the tank bottom surface 43 a in the ball tank 43, and is formed to be inclined downward toward the left frame member 26. The Here, the rail bottom surface 46a of the first ball path portion 46 is formed to be positioned below the tank bottom surface 43a of the ball tank 43, and is set so that a step is formed between the bottom surfaces 43a and 46a. . In the embodiment, the height of the step is set to be approximately equal to the diameter of the pachinko sphere, and a guide surface having a circular arc shape is formed at the step portion. When the pachinko balls flow down to the ball path portion 46, the overlapping pachinko balls are broken to facilitate alignment.

  The second sphere path portion 47 is formed on the front side of the first sphere path portion 46 and extends to the vicinity of the sphere tank 43, and the downstream end of the rail bottom surface 47 a of the second sphere path portion 47. The part is provided with a ball outlet 47b that opens downward. The rail bottom surface 47a of the second ball path portion 47 is formed on the right frame member 27 at an inclination angle substantially equal to the inclination angle of the rail bottom surface 46a (the tank bottom surface 43a of the ball tank 43) in the first ball path portion 46. As it goes, it is inclined downward.

  As shown in FIG. 3 or FIG. 4, a mechanism set board 17 having a ball passage 17 a communicating with the upper and lower ball dishes 14 and 15 is disposed on the back side of the position corresponding to the lower frame member 25. The ball outlet 47b of the tank rail 45 and the ball inlet (not shown) of the ball passage 17a of the mechanism set board 17 are connected to each other via a passage forming member 50. Here, as shown in FIG. 3, the mechanism set board 17 is formed in a size that is substantially hidden behind the lower frame member 25, so that the mechanism set board 17 does not protrude greatly above the lower frame member 25. It is set as follows. As a result, game parts and the like disposed on the game board 19 are prevented from contacting the mechanism set board 17. The passage forming member 50 is provided with a ball payout device 52 (see FIG. 4) for paying out pachinko balls, and the ball payout device 52 is operated based on a predetermined control condition. The pachinko balls that have arrived at the passage forming member 50 are passed through the ball outlet 47b of the tank rail 45 and fed to the upper and lower ball dishes 14 and 15 as prize balls or rental balls. The passage forming member 50 is disposed so as to extend vertically in the vicinity of the left frame member 26, and is spaced backward by a required distance from the back surface of the game board 19 held in the opening region 12a of the middle frame 12. It is attached so that it does not interfere with game parts provided on the game board 19.

(Effects of Example)
Next, the operation of the pachinko machine 10 according to the embodiment will be described.

  In the pachinko machine 10 according to the embodiment, the middle frame 12 includes an upper frame member 24, a lower frame member 25, a left frame member 26, and a right frame member 27, and the frame members 24, 25, 26, and 27 are separate members. In addition, each of the ball tank 43 and the tank rail 45 is formed integrally with the upper frame member 24. That is, since it is not necessary to attach the ball tank 43 and the tank rail 45 separately, the assembling work can be simplified. Further, unlike the prior art, in order to attach the ball tank 43 and the tank rail 45, it is not necessary to extend the mechanism setting panel 17 to a position above the middle frame 12. That is, since it is not necessary to secure an installation area for installing and fixing the mechanism set board 17 above the middle frame 12, it is possible to expand the opening area 12a for installing the game board above the middle frame 12. Therefore, the game board 19 having a large vertical dimension can be assembled to the middle frame 12. That is, by disposing a large game part on the game board 19, it is possible to diversify the game effects, improve the impact, and improve the power, thereby increasing the interest of the game.

  By the way, the pachinko balls stored in the ball tank 43 need to be supplied to the upper and lower ball trays 14 and 15 disposed below the game board 19 on the front side of the pachinko machine 10. In this case, as in the conventional case, when the mechanism set board 17 is extended to the position above the middle frame 12 and the ball passage 17a of the mechanism set board 17 is connected to the tank rail 45, Since it is necessary to secure an installation area for the mechanism set board 17, the size of the opening area 12a for installing the game board in the middle frame 12 is limited. On the other hand, in the embodiment, the ball rail 47b of the tank rail 45 and the ball inlet of the ball passage 17a provided in the mechanism set board 17 are connected to each other by a separately provided passage forming member 50. Forty-five pachinko balls 45 (ball tank 43) are reliably fed to the upper and lower ball dishes 14 and 15. In this way, by providing the passage forming member 50, the pachinko balls of the tank rail 45 (ball tank 43) are moved to the upper and lower ball dishes 14 and 15 without extending the mechanism set board 17 to the vicinity of the tank rail 45. Since it can be fed out, the mechanism set board 17 can be formed in a size corresponding to the back side of the lower frame member 25.

  That is, since it is not necessary to secure the installation area of the mechanism set board 17 provided with the ball passage extending to the vicinity of the tank rail 45 at the side position of the middle frame 12, the opening area 12a for installing the game board is left and right. The game board 19 having a large lateral dimension can be assembled to the middle frame 12. For this reason, large game parts are arranged on the game board 19 to diversify the game effects, improve the impact, and improve the power of the game, thereby increasing the interest of the game. The passage forming member 50 is arranged so as to be separated from the rear surface of the game board 19 provided in the opening region 12a of the middle frame 12 so that the gaming parts of the game board 19 interfere with the passage forming member 50. Can be prevented, and the increase in the size of the gaming parts is not hindered.

  In addition, the tank bottom surface 43a of the sphere tank 43 is formed so as to be inclined downward from the right frame member 27 toward the left frame member 26, and extends to the downstream end side of the sphere tank 43 in a direction along the inclination. By connecting the tank rails 45 in such a manner, the size of the ball tank 43 and the tank rail 45 in the vertical direction can be made compact while maintaining a state where the pachinko balls can flow smoothly. Accordingly, the game parts of the game board 19 are less likely to come into contact with the ball tank 43 and the tank rail 45, so that a larger game part can be disposed on the game board 19. This makes it possible to diversify the game effects, improve the impact and improve the power, and increase the interest of the game.

  Here, in the configuration in which the ball tank 43 and the tank rail 45 face (hide) behind the middle frame 12 (upper frame member 24) as in the prior art, when the opening region 12a of the middle frame 12 is expanded upward, It is difficult to form the ball tank 43 with a sufficient depth. For this reason, sufficient pachinko balls cannot be stored in the ball tank 43, and when a large number of pachinko balls are discharged, such as a big hit, there is a high possibility that a defect such as a broken ball will occur. However, in the pachinko machine 10 according to the embodiment, when the ball tank 43 and part of the tank rail 45 face the rear of the opening area 12a of the middle frame 12, and the game board 19 is installed in the opening area 12a of the middle frame 12. In addition, the ball tank 43 and the tank rail 45 are configured to overlap the game board 19 in the front-rear direction. For this reason, since the depth dimension of the ball tank 43 can be increased to increase the volume of the storage space 44, a large number of pachinko balls can be stored in the ball tank 43.

However, the present invention is not limited to this, and the outer frame that forms the outer shell and the middle frame that is assembled to the outer frame so as to be openable and closable and that holds the game board A front frame that can be opened and closed on the front side of the middle frame, and protects the game board from seeing through; a ball tray that is assembled to the front side of the middle frame; and a ball that is located behind the middle frame and stores game balls A tank, a tank rail that is connected to the ball tank and stored in a row, is arranged in a row and is discharged toward the ball tray, and is disposed on the back side of the inner frame. If it is a game machine provided with the mechanism set board provided with the ball path guided to a plate, conventionally well-known various game machines, such as an arrangement ball machine, can be adopted.

Note that the gaming machine according to the present invention can be limited to the specific configuration shown below.
(A) The gaming machine according to any one of claims 1 to 3, wherein at least the upper frame member (24) is separated from the frame members (24, 25, 26, 27) constituting the middle frame (12). Form possible.
Thus, by making the upper frame member in the middle frame at least a separate member that can be separated, the moldability can be improved and the manufacturing cost can be reduced. In this case, the material of the upper frame member and other frame members can be made different. For example, only the upper frame member may be made of a synthetic resin, and the other frame members may be made of a metal such as an aluminum material to be thinned.
(B) In the gaming machine according to any one of claims 1 to 3 or (A), a part of the ball tank (43) and the tank rail (45) are held by the inner frame (12). It is positioned so as to overlap the game board (19).
As described above, by positioning a part of the ball tank and the tank rail so as to overlap the game board held in the middle frame in the front and rear, the opening area holding the game board in the middle frame can be expanded to a higher position. Can contribute to increasing the size of the game board.
(C) Regarding the gaming machine according to any one of claims 1 to 3 or (A), (B), a ball outlet (47b) of the tank rail (45) and a ball in the mechanism set board (17) A passage forming member (50) is provided that communicates with the ball inlet of the passage (17a).
Thus, it is necessary to provide the mechanism set panel up to the vicinity of the tank rail by providing a passage forming member that connects the ball outlet of the tank rail and the ball inlet of the ball path provided in the mechanism set panel. And can contribute to an increase in the size of the game board. Further, by providing the passage forming member, even when the tank rail and the mechanism set board are arranged separately, the game balls in the ball tank can be reliably discharged to the ball tray.
(D) With respect to the gaming machine according to any one of claims 1 to 3 or (A) to (C), the ball tank (43) has a tank bottom surface (43a) inclined downward toward either the left or right side. The tank rail (45) is connected to the lower end of the tank bottom surface (43a) so as to extend in the direction along the inclination.
