Abstract

PROBLEM TO BE SOLVED: To efficiently reduce noises when a PACHINKO ball collides with a collision surface. SOLUTION: A collision noise reducing device 1 is provided with a polyurethane noise reduction plate 3, spacer 5, and fastener 7 for attaching the noise reduction plate 3 through the spacer 5 to a collision surface 9 or the like. When a PACHINKO ball collides with the noise reduction plate 3, since a gap S1 exists, impulse caused by collision is attenuated by the curve/vibration of noise reduction plate 3, propagated inside the noise reduction plate 3, next propagated to the spacer 5 and the fastener 7 and finally propagated to the collision surface 9. Besides, since a gap S2 exists, impulse applied to the noise reduction plate 3 is attenuated as well by longitudinally or laterally displacing the noise reduction plate 3 corresponding to that impulse. Therefore, noises are not almost generated.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball impact noise reduction device used to reduce noise generated when a pachinko ball collides with a collision surface.

[0002]

2. Description of the Related Art In recent years, in a pachinko game hall, it has been desired to create a quiet and elegant atmosphere to modify the noisy impression of the pachinko game hall and acquire a new customer base.

[0003] However, in the pachinko game arcade, payout of prize balls and circulation of out balls are always performed, and noise is generated due to the pachinko balls falling and colliding with the bottom wall. It was difficult to create a quiet and elegant atmosphere. Therefore, as a technique for reducing the noise generated in this way, for example, a collision noise reduction device described in Japanese Patent Application Laid-Open No. Hei 7-163728 has been proposed. As shown in FIG. 6, this collision sound reducing device uses a sound-reducing plate P with an adhesive or a rivet on a collision surface P3 such as a side wall or a bottom wall with which a pachinko ball collides in a prize ball tank P1.
5 (plate-like elastomer) is fixed in a state of being in close contact, and the noise is reduced by absorbing the impact at the time of collision.

[0004]

However, in the above-described collision sound reducing device, since the sound reduction plate P5 is fixed in close contact with the collision surface P3, the impact at the time of collision is reduced by the sound reduction plate P5. And propagates to the collision surface P3 through the interface, causing noise. Further, since the noise reduction plate P5 is fixed, the pachinko ball tends to rebound, and there is a problem that further noise is generated by the re-collision.

As a means for solving such a problem, it is conceivable to diffuse the impact by increasing the thickness of the sound-reducing plate P5. However, the weight and the material cost are increased, and particularly, in the case of a game machine, the space is reduced. Due to various restrictions,
There is a limit to thickening. Therefore, there is a demand for a technology capable of efficiently reducing noise even when the sound reduction plate P5 is thin.

SUMMARY OF THE INVENTION The present invention has been made in order to meet such a demand, and it is an object of the present invention to provide a pachinko ball impact sound reducing apparatus for efficiently reducing noise when a pachinko ball collides with a collision surface. With the goal.

[0007]

Means for Solving the Problems and Effects of the Invention In order to achieve such an object, the apparatus for reducing the collision sound of a pachinko ball according to the present invention is installed on a collision surface where the pachinko ball collides, and is generated at the time of collision. A collision noise reduction device for a pachinko ball that reduces noise, comprising: an impact-absorbing member made of an elastomer that covers the collision surface; and the shock-absorbing member so that a gap is formed between the impact-absorption member and the collision surface. And a supporting member for supporting the

In the present invention, the shock absorbing member is not mounted in close contact with the collision surface, but is mounted via a support member so that a gap is formed between the impact absorption member and the collision surface. As described above, since the gap exists between the shock absorbing member and the collision surface, the shock absorbing member can bend and vibrate within the range of the gap. The impact generated by the collision of the pachinko ball will be
Damped by vibrating. Further, since the shock absorbing member is not in contact with the collision surface, the shock generated by the collision of the pachinko ball first propagates through the shock absorbing member, then propagates to the support member, and finally propagates to the collision surface. In the impact absorbing member, the impact diffuses radially from the collision point and propagates while attenuating, so that the impact reaching the support member is greatly attenuated. The shock is also attenuated by propagation from the shock absorbing member to the support member and from the support member to the collision surface, and therefore hardly propagates to the collision surface. Therefore, almost no noise is generated.

As described above, according to the present invention, it is possible to obtain an effect that the noise when the pachinko ball collides with the collision surface can be efficiently reduced. Therefore, noise can be effectively reduced even with a thin shock absorbing member.
In the present invention, the shock absorbing member and the support member may be formed of an elastomer.

In this case, the shock is efficiently attenuated in the shock absorbing member and the support member. Therefore, the effect of the present invention, that is, the effect that the noise when the pachinko ball collides with the collision surface can be efficiently reduced becomes remarkable. Further, in this case, the shock absorbing member and the supporting member can be configured as one member. In addition, in the case of such a configuration, there is an effect that the manufacturing process and the assembling process can be simplified.

In the present invention, the shock absorbing member may be supported so as to be relatively displaceable with respect to the collision surface. In this case, the shock absorbing member is not fixed to the collision surface, but is supported so that it can be displaced in response to the applied shock. It is consumed by moving and the like, and can be further attenuated. Therefore, the effect of the present invention, that is, the effect of efficiently reducing the noise when the pachinko ball collides with the collision surface, becomes more remarkable.

Further, in the present invention, there may be provided a distribution member for distributing a traveling direction of the pachinko ball toward the collision surface and dispersing a point of collision with the shock absorbing member. In this case, the traveling direction of the pachinko ball is distributed by the distribution member, so that the pachinko ball does not collide and concentrate at one location. For this reason, the number of times the pachinko balls collide with each other can be greatly reduced. Therefore, in this case, an effect is obtained that the noise generated when the pachinko balls collide with each other can be reduced.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. [Embodiment 1] First, the configuration of the collision sound reduction device 1 of the present embodiment will be described.

FIG. 1 is a side sectional view of the collision sound reducing device. The collision sound reduction device 1 includes a sound reduction plate 3 as a shock absorbing member, a spacer 5 as a support member, a fastener 7 for attaching the sound reduction plate 3 to the collision surface 9 via the spacer 5, and the like.

The sound reduction plate 3 is made of a polyurethane elastomer, and is formed in a flat plate shape. Spacer 5
Is made of a polyurethane elastomer and is formed in a ring shape. The fastener 7 is made of plastic, has a substantially nail shape, and has a tip formed in an arrowhead shape.

Then, as shown in FIG.
A gap S <b> 1 is provided by the spacer 5 between the collision surface 9. Further, the fastener 7 attaches the sound reduction plate 3 to the collision surface 9 by passing through a hole provided in the sound reduction plate 3, a center of the spacer 5, and a hole provided in the collision surface 9. The portion penetrating the sound reduction plate 3 is formed to be thinner than the hole provided in the sound reduction plate 3. For this reason, the sound reduction plate 3 and the fastener 7
And a gap S2 is generated between them.

Next, the collision sound reducing device 1 of the present embodiment is described.
The operation of will be described. Since the gap S1 is provided between the noise reduction plate 3 and the collision surface 9 in the collision noise reduction device 1, the noise reduction plate 3 can bend and vibrate within the range of the gap S1. . For this reason, the impact generated by the collision of the pachinko ball is reduced by the sound reduction plate 3.
Is attenuated by bending and vibrating. The impact generated by the collision first propagates through the sound reduction plate 3, then propagates to the spacer 5 and the fastener 7, and finally propagates to the collision surface 9. In the sound-absorbing plate 3 made of polyurethane, the impact diffuses radially from the collision point and propagates while attenuating, so that the impact reaching the spacer 5 and the fastener 7 is greatly attenuated. The light also propagates in the spacer 5 made of polyurethane while being attenuated. Then, the impact is applied from the sound reduction plate 3 to the spacer 5.
And the propagation to the fastener 7 and the propagation from the spacer 5 and the fastener 7 to the collision surface 9.

In addition, because of the presence of the gap S2, when an impact is given to the sound reduction plate 3, the sound reduction plate 3 is displaced forward, backward, left, right, and the like in response to the shock. Therefore, the impact is consumed as the kinetic energy of the sound reduction plate 3 and is further attenuated. Next, effects of the collision sound reduction device 1 of the present embodiment will be described.

The collision sound reducing device 1 according to the present embodiment has the above-described configuration and operates as described above, so that the following effects can be obtained. Since the shock generated by the collision of the pachinko ball is attenuated by bending and vibrating the sound reduction plate 3 within the gap S1, the noise when the pachinko ball collides with the collision surface 9 is efficiently reduced. Is obtained.

Because of the presence of the gap S1, the impact generated by the collision of the pachinko ball propagates indirectly from the sound reduction plate 3 to the collision surface 9 via the spacer 5 and the fastener 7, so that the impact is very likely to occur during the propagation. Decay. Therefore,
The effect that the noise when the pachinko ball collides with the collision surface 9 can be efficiently reduced becomes remarkable.

Since the spacer 5 is also formed of polyurethane, the shock is absorbed and attenuated even when the spacer 5 propagates through the spacer 5. Therefore, the effect that the noise when the pachinko ball collides with the collision surface 9 can be effectively reduced becomes more remarkable. Due to the presence of the gap S2, the sound reduction plate 3 can be displaced in the front-rear and left-right directions, and the like. Therefore, the effect that the noise when the pachinko ball collides with the collision surface 9 can be reduced more effectively becomes more remarkable.

[Embodiment 2] In this embodiment, a case where the collision sound reducing device 1 is applied to a prize ball payout passage 10 will be described. First, the configuration of the winning ball payout passage 10 of the present embodiment will be described.

3 is a side cross-sectional view of the winning ball payout passage taken along a line XX shown in FIG. 2. The prize ball payout passage 10 is for paying out a prize ball supplied from a well-known prize ball payout device (not shown) to the upper plate 17 or a lower plate (not shown) when a safe hole is won during the game. A prize ball input port 11 communicating with the prize ball payout device, a prize ball sensor 13 detecting passage of the prize ball,
The collision sound reducing device 1 having the upper plate 17 and the rubber tire 15 as a distribution member is provided.

The prize ball sensor 13 is electrically connected to a sound effect generator (not shown). When the prize ball sensor 13 detects the passage of a prize ball, the sound effect generator generates an elegant sound effect. Is configured. In addition, rubber tire 15
Is not a perfect circle, but a figure in which the radius of curvature changes irregularly, and is rotatably attached to the wall surface of the prize ball payout passage 10.

Next, the operation of the award ball payout passage 10 of this embodiment will be described. When a pachinko ball B is supplied as a prize ball from the prize ball insertion port 11 to the prize ball payout passage 10, the pachinko ball B collides with the rubber tire 15 after passing through the prize ball sensor 13. The traveling direction of the pachinko ball B slightly changes to the right in FIG. 2 due to this collision. Further, the rubber tire 15 is rotated by the collision. Then, the pachinko ball B collides with the sound reduction plate 3, and the upper plate 17
Rolls out to

The subsequently supplied pachinko ball B also collides with the rubber tire 15, but since the rubber tire 15 has been rotated by the previous collision, the pachinko ball B collides with a location different from the previous collision location. . Accordingly, the angle of incidence and the angle of reflection of the pachinko ball B on the collision surface of the rubber tire 15 are slightly different from those of the previous time, so that the pachinko ball B after the collision is used.
The traveling direction is different from the previous time, and as a result, the sound reduction plate 3
The location where the collision occurs is also different from the previous time. Further, since the rubber tire 15 is rotated by the current collision, the traveling direction of the pachinko ball B after the next collision is also different. In this way, the traveling direction of the pachinko ball B is sorted, and the points of collision with the sound reduction plate 3 are dispersed.

Next, the effect of the award ball payout passage 10 of this embodiment will be described. The prize ball payout passage 10 of the present embodiment has the above-described configuration and operates as described above, so that the following effects can be obtained in addition to the above effects. The traveling direction of the pachinko balls B is sorted by the rubber tires 15 and the points of collision with the sound reduction plate 3 are dispersed, so that the number of times the pachinko balls B collide with each other can be greatly reduced. Therefore, in this case, the effect that the noise generated by the collision of the pachinko balls B can be reduced can be obtained.

Pachinko ball B by rubber tire 15
Are distributed, and the points of collision with the sound reduction plate 3 are dispersed, so that the effect of suppressing the deterioration of the collision sound reduction device 1, particularly the sound reduction plate 3, can be obtained. When the passing of the pachinko ball B is detected by the prize ball sensor 13, a sound effect is generated, so that an effect that an elegant atmosphere can be created can be obtained.
