Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a ball game machine.

[0002]

2. Description of the Related Art A ball hit in a game area set on the front of a game board falls through an obstacle nail and falls into the prize hole during which a prize ball is released, which leads to the release of the prize ball. Or it may lead to the start of the game to be set. On the other hand, the other hit balls are received by the lower half of the inner band that surrounds the lower part of the game area, are collected at the lowermost part by the arc-shaped band of this lower half, and are guided to the out ball opening that opens to this. It becomes an out ball and is released outside the system.

Depending on how the game is set, there is a difference in the ratio of out balls to the number of shot balls (hit balls).
Most of the struck balls that have been fired become out balls and fall into the lower half of the inner band, where they are collected at the out ball mouth. At this time, since many conventional ball game machines (mainly pachinko machines, hereinafter simply referred to as game machines) are formed by surrounding the game area with an inner band made of a metal strip plate, a steel ball hitting ball is formed. When a large number of objects fall and collide with this inner band, a considerable collision sound is emitted. Since this collision sound is continuous, it becomes a considerable noise, which is a cause of deteriorating the environment of the game arcade.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention is intended to suppress the generation of the collision sound of a hit ball that falls into the inner band and becomes an out ball, and solves the noise generated by the collision sound. As described above, in the case of an inner band made of a metal strip, it is extremely difficult to avoid the noise generated from the collision, because when hitting a ball, a collision occurs between the metals.

For this reason, a method of forming the inner band of the portion concerned with a synthetic resin material to absorb impact noise has been attempted, but in the past, in general, a hard synthetic material was used to form a certain shape. Since it is made of a resin material, its own rigidity causes the generation of collision noise, and the generation of noise cannot be suppressed. In addition, the static electricity, which had been achieved when using a conductive metal material, could not be removed, and as a result, it was brought into the mechanical section on the back of the game board as it was, which adversely affected various electrical equipment. was there.

Therefore, in view of these points, the present invention eliminates the collision noise of a hit ball generated by dropping along the game board surface and colliding with a band member surrounding the lower part of the game area. A ball-ball game in which static electricity charged on the hit ball while being guided along and collected in the out-ball mouth is eliminated to effectively avoid adverse effects on electric devices such as a game control circuit installed in the gaming machine. It is intended to provide a machine.

[0007]

In order to achieve the above object, the present invention uses a material having a cushioning property for a band member surrounding a lower portion of a game area set on the front surface of a game board and also having a vibration-proof property. Forming and receiving a hit ball falling in the game area directly with the band member and guiding it to the out ball mouth, a conductive member is provided in parallel with the band member and guided along the band member The purpose is to make contact with the hit ball and eliminate the static electricity charged on the hit ball.

As a specific material for the band member, there is, for example, rubber or synthetic resin material. As the synthetic resin material, a soft synthetic resin material is preferable. One reason is that the impact absorption is excellent, and the collision noise generated when the ball hits is small. For this band member, it is more preferable to use a flexible rubber or soft synthetic resin material that has a small repulsive force and does not repel a hit ball that falls. This is because the characteristics of these materials are that they have anti-vibration performance, and when a hit ball falls and collides, it jumps up and collides with other hit balls, or avoids producing noise by colliding with glass.

Further, the band member is formed in an arc shape surrounding a substantially lower half portion of a game area formed in a substantially circular shape on the front surface of the game board, and falls without winning any winning opening,
It is desired that the hit balls collected at the out-ball mouth, that is, the entire range of receiving the out-ball, be attached.

The object of the present invention is to eliminate the noise generated by the hitting ball which falls in the game area and is finally collected in the out-ball mouth due to the collision with the inner band which cuts the lower part of the game area. Therefore, it is desired that the band member is provided over the entire range of the area where the band member collides with the falling member. However, the noise is generated as the inner band approaches a horizontal state, that is, as the inner band approaches the out ball entrance, the collision collides vertically and the collision becomes more intense, and a loud collision sound is generated.Therefore, it should be provided only near the out ball entrance. May achieve the object of the present invention.

On the other hand, in the present invention, the conductive member may be a synthetic resin material having iron powder deposited on the surface, or a synthetic resin material mixed with iron powder to have conductivity. Further, the conductive member may be a conductive wire or tape-shaped material attached along the upper surface of the band member. However, a conductive metal plate such as a steel plate is advantageous and suitable from the viewpoint of effect and in terms of cost.

Since the conductive member is received by the band member and contacts the hit ball guided toward the out-ball mouth to eliminate static electricity charged on the hit ball, it is attached to a position where the hit ball contacts. become. Therefore, when the band member is attached in an arc shape so as to surround the lower part of the game area, and if it is attached with a required length, it is attached in parallel along this length, and the contact relationship with the hit ball is It is good to have a lot.

In order to improve this contact relationship, the conductive member provided in parallel with the band member is provided behind the band member, that is, between the front surface of the game board and the upper surface of the band member on the trailing edge side. When the ball is formed in a downward slope toward the out-ball mouth, the ball is guided near the front of the game board so that the contact between the ball and the conductive member becomes close. Therefore, a better condition can be obtained.

As is clear from the above description, since the present invention has a relationship in which the band member and the conductive member are arranged side by side, it is desirable that both are integrated when attached to the front surface of the game board. In particular, it is important to integrate the two in order to secure the positional relationship between them and to ensure the contact between the ball hitting the band member and the conductive member and to facilitate this positional relationship in the assembly process. is there.

According to the present invention, in order to achieve this, an engaging recess is formed on the back surface of the band member, and a locking claw protruding forward is provided on the conductive member, and the locking claw is inserted into the engaging recess. While the band member and the conductive member are engaged with each other, the conductive member is clamped and fixed by fixing the band member to the front surface of the game board, and both are integrated, and at the same time, to the game board. It can be installed. Less than,
The present invention will be described according to the illustrated embodiments of the invention, and the features of the present invention will be clarified.

The hit ball P fired from the launching device jumps into the winning openings 6, 7 to the winning device 10 while passing through these to become a safe ball (winning ball), and the variable display device can be moved, Promotes the release of prize balls.

On the other hand, a hit ball that has not entered either the winning port or the winning device is received by an inner band surrounding the lower portion (bottom portion) of the game area 4, and is formed and formed at the lowest portion thereof. You will be guided to the Out Exit 11 (Ineffective Exit),
Through this, it is released to the outside of the system.

Reference numeral 12 in the drawing denotes a band member arranged at the bottom of the inner band 2 by replacing the inner band 2 made of this metal band plate. Reference numeral 13 is a metal conductive member attached in parallel along the band member 12.

As described above, the band member 12 is located at the lower portion of the inner band 2 that receives the hit ball P hit in the game area 4 without falling, and instead of the inner band. It is intended to catch falling hit balls. And, further, this is the outermost ball mouth 1 at the bottom.
It is for guiding to 1, and prevents the generation of a collision sound when falling.

The band member 12 here is formed in a circular arc shape using a soft synthetic resin as a material, and the front and rear wall thicknesses thereof are made equal to the width of the inner band 2 over the entire length thereof, and the upper surface thereof is formed. A hit ball falling on the portion 12a can be received. Then, as shown in FIG. 2, the upper surface portion 12a is tilted from the front edge portion toward the rear edge portion with an inclination so as to have a slight downward slope, and the hit ball is guided toward the rear edge portion side to lean it close to each other. In this state, it is guided to the downstream side, that is, the out-ball mouth.

In this embodiment, as shown in FIG. 2, a part of the upper surface portion 12a is cut along the entire length to form a shallow groove 14, and a strip-shaped rubber buffer plate 15 is formed in this groove 14. Is fitted to absorb the impact of the hitting ball P that falls and to further reliably prevent the generation of collision noise. The provision of the buffer plate 15 is more effective in preventing collision noise when the band member 12 is molded from a hard synthetic resin, but when the band member 12 itself is soft and flexible, as will be described later. May omit this.

In this embodiment, the soft band member 12 is combined with a conductive member 13 formed of a metal material to have a required rigidity so as to maintain a constant shape, and by this combination, a game board. It is designed so that it can be easily attached at a predetermined position when it is attached to the.

As shown in FIG. 5, the conductive member 13 is formed in an arc shape in conformity with the shape of the band member 12, and the outermost opening 11 of the game board 1 is surrounded in the center portion which is the bottommost portion. The annular portion 16 is formed. A plurality of locking claws 17 for raising the claws 17a are provided at appropriate positions on the lower edge portion, and the band member 12 is hooked via the locking claws 17.

On the other hand, the band member 12 is formed with a plurality of engaging recesses 18 having grooves 18a for pushing the claws 17a on the back side corresponding to the locking claws 17, and these locking recesses 1
The engaging claws 17 are hooked on 8 to engage with the conductive member 13.

The band member 12 and the conductive member 13 are put together on the front surface of the game board 1 in the above-mentioned combined state, and the band member 12
It is fixed to the front surface of the game board integrally with the conductive member 13 by driving a nail through the through hole 19 drilled in. And
As shown in FIG. 1, the band member 12 is fixed in an arcuate state by hammering the nails and coupling with the conductive member 13 by the locking claws 17 therebetween, so that the lower part of the game area 4 is securely surrounded. become.

By the way, the band member 12 is incorporated in a part of the inner band in order to receive the hit ball P falling in the game area 4. However, the band member 12 does not fall into a winning opening or the like and falls. Since it is arranged in order to prevent the generation of the hitting sound of the hitting ball, it may be installed in the range where the hitting sound of the falling ball is generated.

Therefore, in the present embodiment, as shown in the drawing, the inner band 2 is attached over a wide range connecting the left and right side edge portions of the game area 4 and is structured so as to receive all falling hit balls. The range may be narrowed to surround both sides of the out-ball opening 11. That is, specifically, the length of the band member 12 shown in the figure is shortened (for example, approximately 3
The band member 12 is arranged so as to surround a portion where the inner band 2 becomes nearly horizontal (with a length of about one-half) so that the falling hit balls are concentrated and collide with each other at a nearly right angle.
The effects of the present invention can be obtained even if the above are arranged.

Further, it is more effective that this band member buffers when the hit ball is dropped, and at the same time, eliminates the bounce to avoid the collision of the balls with each other or the collision with the glass covering the front surface. Therefore, for this band member, a material having a shock absorbing property as well as a vibration absorbing property for absorbing a collision, for example, an anti-vibration rubber mixed with iron powder becomes more suitable.

Regarding the conductive member 13, as shown in FIG. 6, when a piece 20 having a slightly downward slope is extended rearward from the lower edge portion 16a of the annular portion 16 and fixed to the game board 1. This piece is inserted into the out-ball mouth 11, and the hit ball that has become an out-ball rolls on this piece.

Further, the upper surface of the bottommost portion 12b of the band member 12 along the lower edge portion 16a is cut to be thinned so as to match the hole shape of the out ball opening 11,
As shown in FIG. 6, the upper surface thereof is formed to have a downward slope toward the rear so that an out ball guided by the band member 12 and flowing into the band member 12 can be directed toward the rear and sent out onto the piece 20.

Reference numerals 21 and 22 in the drawing are ground wires for discharging static electricity charged in the conductive member 13. One ground wire 21 is pulled out to the back through the out ball opening 11 provided in the game board 1, and a mechanism plate (not shown) on the back of the front frame
Further, the ground wire 22 is connected to the edge of the mechanism plate exposed on the side of the game board, or to the metal frame portion of the glass 23 covering the front surface of the game board to discharge each.

The present invention is constructed as described above, and the hit balls that have been hit in the game area 4 and have not jumped into the winning port or the like while falling are the upper surface of the band member 12 that surrounds the lower part of the game area as it is. It falls on the portion 12a and is received by the buffer plate 15 attached thereto. Therefore, since the hit ball P does not collide with the inner band 2 made of a metal plate as in the conventional case, it does not generate a collision noise and is quietly collected and guided to the out-ball mouth 11. Become.

At the same time, the hit balls P collected through the band member 12 come into contact with the conductive member 13 arranged in parallel with the band member while rolling on the upper surface portion 12a, so that the ball P can be launched and the game area can be changed. While passing, the static electricity that charges the ball will be discharged.

In the present embodiment, since the upper surface 12a of the band member 12 is inclined rearwardly, the hitting ball guided by the upper surface 12a is set closer to the game board side, that is, between them. The conductive member 13 is guided to the out-bulb opening 11 in a state of being in contact with the conductive member 13, and the discharge of the static electricity is further ensured.
