It should be noted that the shooting ball contact portion 62d is a portion on the guide rail 62 where a game ball that has jumped over the foul flow lowering opening 31 can come into contact, and when the hitting force of the shooting device 29 is minimized, It refers to the range (see FIGS. 3 and 4) from the position where the ball strikes to the position where it strikes when the hitting ball firing force is maximized.

  The guide rail 62 is basically (for example, when a player launches a game ball at a position where the player can easily hold the launch operation handle 15, or when the launching force of the launching device 29 is in the middle of the adjustable range). ), The game ball is brought into contact with substantially the center of the launch ball contact portion 62d in which the shot ball impact absorbing space portion 82 is formed on the back surface.

  More specifically, the firing ball guide member 61 is configured such that the portion of the firing ball guide wall portion 67 that faces the firing ball contact portion 62d of the guide rail 62 attached to the firing ball guide member 61 is guided by the guide guide path 60. The projecting ball contact portion 62d and the projecting ball guide wall portion 67 are spaced apart from each other. The projecting ball contact portion 62d has both ends in the longitudinal direction, that is, the contact position of the game ball with the minimum hitting ball firing force and the hitting position with the maximum hitting ball firing force. It is supported in the state of what is called a both-ends support beam from the opposite side to the guide guiding path 60 by the edge part formed in the middle.

  As shown in FIG. 9, the launch ball impact absorbing space portion 82 is viewed from the front side with the gap between the guide rail 62 and the launch ball guide wall portion 67 gradually narrowing toward one end (the upper end in the figure). Sometimes it may be a substantially triangular space.

  As described above, when the launch ball impact absorbing space portion 82 is provided on the back side of the launch ball contact portion 62d (opposite to the guide guide path 60), when the game ball from the launch device 29 hits the guide rail 62, The guide rail 62 can be bent slightly by being pushed by the launching ball impact absorbing space 82 without restraining the movement to be recessed into the launching ball guide wall 67 by this contact. Therefore, even if the game ball hits the guide rail 62, the impact is absorbed and it is difficult to bounce, and unevenness in flight can be reduced. Therefore, the player can operate the launching device 29 to send the game ball to the game area 11 as intended, thereby enhancing the interest of the game.

  Further, as shown in FIG. 10 (b), the guide rail 62 of the present embodiment is provided with a notch 84 at the side end near the mounting base portion 66 of the launching ball contact portion 62d, and the launching ball impact absorbing space portion. The width of the guide rail 62 at the location facing the reference numeral 82 is made narrower than the width of the rail at other locations, so that the projecting ball contact portion 62d and the mounting base portion 66 are separated from each other.

  With this configuration, the guide rail 62 and the mounting base portion 66 are not rubbed when the game ball hits the launch ball hitting portion 62d of the guide rail 62. Therefore, the launch ball contact portion 62d of the guide rail 62 can smoothly move toward the launch ball impact absorbing space portion 82, and the ball of the game ball can be reliably relieved.

  As shown in FIG. 11, the firing ball guide member 61 has a plurality of positioning bosses 86 (two in the upper and lower directions in this embodiment) protruding from the back side of the mounting base portion 66. The positioning boss 86 has a tapered tip so that it can be easily fitted into a mounting hole 87 formed in the rectangular plate 40, and a ring groove formed at the base portion that is one step lower than the back surface of the mounting base portion 66. A cell-shaped escape portion 88 is provided. Therefore, when the projecting ball guide unit 43 is attached to the rectangular plate 40, even if the cell sheet 41 has a warped portion (so-called burrs or burrs) around the mounting hole, the cell escape portion 88 accommodates the warped portion. The mounting base portion 66 can be brought into close contact with the surface of the game board 5.

Then, the fixing member 90 of the guide rail mounting boss 76 is removed, the locking state of the guide rail locking portion 62a is released, and the guide rail 62 is pulled out to the front.

  Thus, the guide rail 62 attached on the game board 5 can be easily attached and detached by the above-described procedure even when the launch ball guide unit 43 (launch ball guide member 61) is attached to the game board 5. . Therefore, it is possible to improve the efficiency of assembling the game board 5 and cleaning or replacing the guide rail 62 in the game store.

  In the embodiment described above, the launch ball impact absorbing space portion 82 is formed between the launch ball contact portion 62d of the guide rail 62 and the launch ball guide wall portion 67. However, as shown in FIG. The buffer member 95 may be stored in the absorption space portion 82. For example, in the embodiment shown in FIG. 12 (a), the buffer member 95 is composed of a plurality of coil springs 96, one end of which is a launch ball contact portion 62d of the guide rail 62 and the other end is a launch ball impact. The guide rail 62 is urged toward the guide guide path 60 to such an extent that the guide rail 62 is not separated from the shot ball guide wall portion 67 by being locked to the shot ball guide wall portion 67 facing the contact portion 62d.

  In the embodiment shown in FIG. 12B, a buffer bag 97 filled with a fluid, for example, a gas bag filled with gas under pressure, or a liquid bag filled with liquid is used as the buffer member. Specifically, the buffer bag 97 has substantially the same volume as the launch ball impact absorbing space portion 82, and a bag is formed by a jacket material 98 having flexibility such as vinyl or rubber. Gas or liquid (specifically, air or water) is sealed in the bag. When such a buffer bag 97 is stored in the launch ball impact absorbing space 82 without any gap, the buffer bag 97 has one side as the launch ball contact portion 62d of the guide rail 62 and the other side as the launch ball contact portion 62d. It comes into contact with the opposed projecting ball guide wall 67. Then, when the game ball fired from the launching device 29 passes through the foul flow lowering port 31 and hits the launching ball contact portion 62d, the impact due to the impact of the launching ball is transmitted to the buffer bag 97 through the launching ball contact portion 62d. The shock absorbing bag 97 can disperse this impact throughout the fluid (gas or liquid) in the shock absorbing bag 97.

  As described above, the launch ball guide member 61 is provided with the buffer member 95 that reduces the impact from the game ball that abuts against the guide rail 62 in the launch ball impact absorption space portion 82, so that the guide rail 62 receives from the game ball. The shock can be dispersed and absorbed also in the buffer member 95 to prevent the guide rail 62 from being damaged.

  In addition, since the shock absorbing member 95 is a gas bag or a liquid bag, the impact received locally at the launching ball contact portion 62d can be distributed over the entire shock absorbing member, and the ball of the game ball can be more reliably mitigated. In addition, it is possible to suppress unevenness of the flying ball.

  In the above-described embodiment, a pachinko gaming machine which is a typical ball game machine has been described as an example. However, the present invention is not limited to this, and a game ball is driven from a launcher into a game area through a guide guide path. Any game machine may be used as long as it is a ball game machine that performs a game. For example, it may be a ball game machine such as an enclosed ball type pachinko machine, an arrangement ball type game machine, or a sparrow ball type game machine that circulates a game ball enclosed inside.

  It should be understood that the above-described embodiment is illustrative in all respects and not restrictive. The present invention is not limited to the above description, but is defined by the scope of the claims, and includes all modifications within the scope and meaning equivalent to the scope of the claims.
