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, the ball bounced by the ball cage 21 is driven from the ball launch rail 3 through the guide rail 4 into the game area 11 of the game board 1, but in the game area 11 due to insufficient hitting power. 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 collect the return ball, conventionally, a gap 5 for taking in the ball is provided between the guide rail 4 and the ball launching rail 3, and a return passage 6 for returning the return ball to the lower plate below the gap 5 is provided. 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. If the inclination of the guide rail 4 becomes tight, the return ball will also return vigorously, so that the return ball that has conventionally fallen into the gap 6 is placed on the upper end of the side surface 31 of the ball launch rail 3 as shown in FIG. 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 clearance for taking in a return ball is provided between the launch rail and the guide rail, and a rail auxiliary member having a guide rail side surface inclined at 45 ° or less with respect to the game board surface is disposed in the clearance, A ball collection passage for collecting a return ball that collides with the side surface is provided beside the ball launch passage.

  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.

  In the game machine return ball collecting structure according to the present invention, the rail auxiliary member having the guide rail side surface inclined at 45 ° or less with respect to the game board surface is disposed in the ball take-in clearance, so that it collides with the side surface. The rebounded ball can be bounced back to the front (player side) or back of the gaming machine at an angle of 90 ° or more. 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 delivered sphere is placed on the launch position 29 on the sphere launch rail 3 made of metal and having a V-shaped valley section (FIGS. 4 and 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. The bullet passes through the V-shaped valley 32 of the ball launch rail 3, is guided by the curved guide rail 4, passes through the ball launch passage 42 between the guide rail 4 and the inner rail (not shown), and 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 a collision, a gap 5 for returning the return ball is provided between the guide rail 4 and the ball launch rail 3. A resin rail auxiliary member 8 having a guide rail side surface 81 inclined from the guide rail 4 side toward the ball launch rail 3 side is disposed in the gap 5. 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 has a gentle slope 81a on the guide rail 4 side inclined at θ1 = 15 ° with respect to the game board surface 12, and θ2 = 45 on the opposite side (= the ball launch rail 3 side). It consists of a steep slope 81b inclined at 0 ° and a curved surface 81c between the two slopes 81a, 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 the chevron guide 82 is formed slightly lower (about 1 mm) than the ball launch rail 3, it does not affect the movement of the ball driven into 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 is formed in a curved surface having a concave cross section at the center, and the V-shaped valley 32 of the ball launching rail 3 is shifted forward by about 1 mm on the player side, that is, from the bottom of the V-shaped valley 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.
