Description

  According to the present invention, a return ball of a gaming machine for collecting a ball that has returned to the guide rail due to a defective launch without arriving at the game area as a result of firing the ball on the launch rail toward the upper game area. It relates to the recovery structure.

In a pachinko machine that is a conventional gaming machine, for example, as shown in FIG. 10, a ball launcher 2 including a ball cage 21 is disposed on the lower right side of the game board 1. In this pachinko machine, spheres repelled by Tamadamatsuchi 21 is driven into outgoing morphism rail 3 from the guide rail 4 along with the game area 11 of the game board 1, in the game area 11 or the like hitting lack The sphere that has not arrived becomes a return sphere, travels backward in the sphere launch path 42 between the guide rail 4 and the inner rail 41, and collides with the subsequently launched sphere. Therefore, in order to recover the returned ball, conventionally a gap 5 for Tamato write between the guide rail 4 and the outgoing morphism rail 3, the collection path back to the lower tray of the returned ball below the gap 5 6 Was established.

However, in recent years, in order to increase the game area 11 with the increase in the size of the center role, the ball launcher 2 is often arranged on the left side from the center of the game board 1, and as a result, the guide rail 4 The slope is tight. It means that the inclination of the guide rail 4 returns may return, but the ball momentum if tightly, conventionally returned ball had fallen into the gap 6, as shown in FIG. 11, the upper end of the side surface 31 of the origination morphism rail 3 There was a situation where it collided and jumped up and collided with the following ball. Once such a ball collision occurs, ball collisions occur one after another in a chain, which makes it impossible to continue the game.

  In Patent Document 1, in order to avoid a collision with the following sphere, a return sphere collision body 55 having a course changing surface 61 is provided at the lower part of the guide rail, and the traveling direction of the return sphere P2 colliding with the course changing surface 61 A return ball recovery device is disclosed that is directed diagonally downward to the right. However, since the return path X2 of the return sphere P2 intersects the launch path X1 of the launch sphere P1 on the same plane, there is still a problem that the risk that the launch sphere P1 and the return sphere P2 collide still remains.

JP 2007-151679 A (FIG. 1)

  In view of the above-described conventional problems, an object of the present invention is to provide a return ball recovery structure for a gaming machine for recovering a return ball that has failed to fire without colliding with a subsequent ball.

The return ball collection structure of the gaming machine made to solve the above problems is the result of launching the ball on the launch rail from the ball launcher provided on the game board toward the game area of the game board via the guide rail In the return ball collection structure of the gaming machine for collecting the return ball that has failed to launch,
A gap is provided between the firing rail and the guide rail for taking in the return ball, and in this gap, the side surface of the guide rail that causes the return ball that has returned on the guide rail to collide with the launch rail is gradually played as it approaches the launch rail. away from the board, with disposing the rail auxiliary member is inclined at an angle of 4 5 ° or less with respect to the game board, the ball recovery passage for recovering the returned ball impinging on the side of the sphere firing passage It is provided sideways.

  In the above-described invention, the inclination angle of the side surface on the return sphere inlet side can be reduced, and the return sphere outlet side can be increased. In addition, a chevron guide can be provided on the upper surface of the rail auxiliary member so that a part of the side surface can be formed higher, and further, the guide rail can be installed in a cross-section arc shape and shifted rearward from the firing rail. it can.

The return ball collecting structure of the gaming machine according to the present invention gradually separates the side surface of the guide rail that causes the return ball that has returned on the guide rail to collide with the space for taking in the ball from the surface of the game board as it approaches the launch rail. direction, since the disposed rail auxiliary member is inclined at an angle of 4 5 ° or less with respect to game board, the gaming machine forward sphere impinging on the side at an angle of more than 90 ° (player side) or Can bounce backwards. Therefore, since the return ball can be shifted laterally from the ball launch path, it does not collide with the following ball. Further, by changing the inclination angle of the side surface from small to large, the impact of the return sphere colliding with the side surface can be made small, and the rebound of the sphere can be reduced to smoothly change the direction. In addition, since the angle guide is provided and the guide rail side surface of the rail auxiliary member is raised on the triangular side surface of the angle guide, the return ball can be more reliably collided with the guide rail side surface. Furthermore, since the guide rail is installed behind the firing rail, the effect of the Yamagata guide can be further exhibited.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 is a front view of a game board 1, and a ball launcher 2 is disposed on the lower left side of the game board 1.
2 to 5 are perspective views showing a return ball collection structure according to the present invention. The ball launching device 2 has a ball supply unit 23, a ball launch unit 24, and a return ball collection passage unit 25. (FIG. 2). The sphere supply unit 23 sends the spheres fed from the supply passage 26 one by one to the supply port 28 by the rotor 27 (FIG. 3). The sent spheres is placed in firing position 29 on the section V-shaped valley shape of the origination morphism rail 3 made of metal (Figure 4,5). The ball launching unit 24 has a plunger type solenoid 7, and a plunger 71 that protrudes when energized plays a ball at the launch position 29. Pinball passes through the V Jitani 32 of the origination morphism rail 3, through the ball firing path 42 between is guided by the curved guide rail 4 by the guide rail 4 and the inner rail (not shown), the game board It is driven toward one game area 11.

A ball that has not arrived in the game area 11 due to a lack of hitting force or the like will run backward in the ball launch path 42 on the extension line of the V-shaped valley 32 and collide with a subsequently launched ball. Therefore, in order to prevent collisions, is between the guide rails 4 and outgoing morphism rail 3, the gap 5 for returned ball capture is provided. Then, this gap 5, the rail support member 8 made of resin having a guide rail side surface 81 which is inclined towards the rail 3 side elevation guide rail 4 side or al onset is disposed. Further, the collection passage 6 for collecting the return sphere that has collided with the guide rail side surface 81 communicates with the gap 5 and is equal to or more than one sphere on the side facing the guide rail side surface 81 next to the ball launch passage 42. It is set off.

As shown in FIG. 6, the guide rail side surface 81 is a gentle slope on the side of the guide rail 4 that is inclined at θ1 = 15 ° with respect to the game board surface 12 in a direction away from the game board surface 12 as it approaches the launch rail 3. and 81a, consisting of a steep 81b tilted at .theta.2 = 45 ° on the opposite side (= originating morphism rail 3 side), two slopes 81a, a curved surface 81c between 81b. Since the guide rail side surface 81 has a small inclination angle on the return sphere entrance side and a large inclination angle on the exit side, the collision force of the return sphere can be reduced and the direction can be smoothly changed.

  Further, as shown in FIG. 7, the guide rail side surface 81 may be composed of a single plane inclined at an angle of θ3 = 45 ° or less with respect to the game board surface 12. The ball colliding with the guide rail side surface 81 is rebounded with an obtuse angle of 90 ° or more with respect to the game board surface 12. Therefore, since the return ball can be shifted laterally (forward in this embodiment) from the ball launch passage 42, it does not collide with the following ball. Even when the return ball collides with the upper end 81e of the side surface 81 on the guide rail side, the upper end 81e is inclined at 45 ° or less (FIG. 4), so the return ball does not bounce straight up, It bounces upwards. Accordingly, it is possible to shift the return sphere laterally from the sphere launch passage 42 by one sphere or more. Further, since the return ball collides with the side wall 25a of the recovery passage portion 25 below the lower end 81d of the guide rail side surface 81 with the momentum of dropping, the ball colliding with the side wall 25a does not return to the ball launch passage 42. (FIG. 6). Further, the upper portion 25b of the side wall 25a is inclined inward to prevent the balls from jumping out.

On the upper surface of the rail auxiliary member 8, there is provided a mountain-shaped guide 82 that is inclined toward the collection passage 6 side (FIGS. 5, 6, and 8 (a)). Since Yamagata guide 82 is formed lower slightly than calling morphism rail 3 (about 1 mm), so as not to affect the movement of the driven sphere toward the game area 11 by the solenoid 7. As a result, the height of the guide rail side surface 81 can be increased by the triangular side surface 82a of the mountain guide 82 to increase the cross-sectional area (FIG. 5), and the return ball can be more reliably connected to the guide rail side surface. It can be made to collide with 81 and be excluded in the collection passage 6. In addition, it is more preferable that the cross section of the mountain-shaped guide 82 is formed in an arc shape having a radius slightly larger (about 1 mm) than the sphere, because the cross-sectional area can be further increased without affecting the movement of the sphere ( FIG. 8B). In addition, the angle guide 82 may be provided over the entire upper surface of the rail auxiliary member 8, but the recovery path is extremely unlikely to collide with the return ball because the guide rail side surface 81 is inclined with respect to the game board surface 12. It is desirable to omit the 6 side and use only the game board surface 12 side as in the embodiment.

Further, the guide rail 4, in terms of the center of the recessed cross section was formed on the lower curved surface, by shifting 1mm approximately in front of the player side V Jitani 32 of the origination morphism rail 3, i.e. from the bottom of the V Jitani 32 It can arrange | position so that the bottom of a concave curved surface may be located in the game board surface 12 side (FIG. 9). In this case, the fired ball moves on a plane M parallel to the game board surface 12 and passing through the bottom of the V-shaped valley 32. However, in the ball launch path 42, the cross-section of the guide rail 4 is gradually curved. It is drawn to the game board surface 12 side and moves on the plane N passing through the bottom of the curved surface located behind the plane M. Therefore, since the return ball returns from the bottom of the V-shaped valley 32 to the game board surface 12 side, it will collide with a higher position of the triangular side surface 82a of the mountain guide 82 provided on the game board surface 12 side. The effect of 82 will be exhibited more.

  As described above, according to the present invention, the return sphere can collide with the guide rail side surface 81 of the rail auxiliary member 8 and can be eliminated laterally from the sphere launch passage 42. It can be reliably recovered without collision.
