Abstract

PROBLEM TO BE SOLVED: To provide a pachinko machine which can lengthen the stay time of a game ball on a board face in the state of avoiding miniaturization and complication of a center display part by providing the center display part with a bearer which the game ball hits. SOLUTION: The shot game ball enters a game part and hits a first slowdown nail 80L. A game ball M that hit the first slowdown nail 80L slows down and then hits a bearer 74L. The game ball M that hit the bearer 74L rebounds upstream. The game ball M falling from the downstream end part of the bearer 74L hits a second slowdown nail 82L and returns to the bearer 74L with prescribed probability. With the first slowdown nail 80L, bearer 74L and second slowdown nail 82L thus provided, the stay time of the game ball M on the board face can be lengthened in the state of avoiding miniaturization and complication of a center display part 40.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine provided with a center display unit provided with accessories, indicators and the like.

[0002]

2. Description of the Related Art Generally, the longer a flowing path of a game ball is,
It is preferable to design the pachinko machine so that the game balls are located between the nails on the upstream side of the game board as much as possible or between the winning tools, because the game balls at the upstream position have a high expectation for winning. .

[0003] In other words, the more the game ball is located at the downstream position, the smaller the winning hole is, while the closer the player is to the outmost hole at the most downstream position, the lower the expectation of winning the game ball.

In view of the above, various types of conventional pachinko machines have been developed so as to reduce the falling speed of the game balls so that many game balls can be left on the game board surface.

For example, in a pachinko machine described in Japanese Patent Application Laid-Open No. 2000-24190, the right and left sides of a roof portion (so-called "armor portion") formed from the top to the shoulder of a center display portion such as an accessory or a display. The projections are integrally formed at substantially the lower end portions of the game balls, and nails are implanted so as to face the projections to reduce the speed of the game ball.

However, in this pachinko machine, a game ball is received by a projection, but since this projection is formed integrally with the roof portion, the surface area is reduced. For this reason, there is a problem that the contact area with the game ball becomes small and it is difficult to surely decelerate the game ball. Further, even if the game ball is received by the projection, the contact area with the game ball is small, so that there is a problem that it is difficult to bounce the game ball upstream and decelerate.

As another conventional example, there is a pachinko machine in which the shape of a center display portion such as an accessory and a display device is made smaller and more nails are arranged so that the falling speed of a game ball is slowed down in relation to the nails. However, in the current mainstream models, the liquid crystal of the display tends to be large, so there is naturally a limit to reducing the center display section, and there is a problem that many nails cannot be arranged.

On the other hand, when the center display portion is formed large,
A so-called warp for taking game balls into the space from above the center display unit, and a slope for reciprocating the taken game balls are provided. There is a pachinko machine that allows a player to see the movement of a game ball on a game board by staying at the game board. In this pachinko machine, the player is given an expectation that a game ball flying on the game board (mainly in the center display section) will win. However, in such a pachinko machine, since the warp and the slope are formed, the structure of the center display unit cannot be simplified. In other words, there is another problem that the structure of the center display unit is complicated and it takes time to design.

[0009]

SUMMARY OF THE INVENTION In view of the above, the present invention provides a pedestal on which a game ball hits the center display unit, thereby minimizing the size and complexity of the center display unit. It is another object of the present invention to provide a pachinko machine capable of surely decelerating a game ball and prolonging the time the game ball stays on a game board.

[0010]

According to a first aspect of the present invention, there is provided a pachinko machine in which a center display portion is provided on a game board, and a cradle on which a shot game ball hits is provided on the center display portion. It is characterized by having been provided.

Next, the operation and effect of the pachinko machine according to the first aspect will be described.

On the game board surface, there is provided a center display unit having an accessory, a display and the like. The center display unit is provided with a receiving stand.

Here, the shot game ball hits the upper portion of the center display section or the like, falls along the center display section, and hits the cradle. The game ball hitting the cradle jumps upstream. In this way, by hitting the game ball to the receiving table, the time that the game ball stays on the game board can be lengthened, and the player can be expected to win the game ball.

As a result, there is no need to reduce the size of the center display unit and increase the number of game nails, and to provide a warp or a slope in the center display unit without complicating the structure of the center display unit. With a simple configuration such as providing a cradle, falling of the ball can be delayed.

According to a second aspect of the present invention, the pachinko machine has a down slope.

Next, the operation and effect of the pachinko machine according to the second aspect will be described.

Since the cradle has a downward slope, it is possible to prevent game balls from staying on the cradle.

The cradle may be formed of a flat surface or a curved surface as long as the cradle has a downward slope.

According to a third aspect of the present invention, in the pachinko machine, first deceleration guide means for hitting the game ball is provided upstream of the receiving table.

Next, the operation and effect of the pachinko machine according to the third aspect will be described.

A first deceleration guide is provided upstream of the cradle. For this reason, since the shot game ball hits the first deceleration guide means before hitting the center display portion or the cradle, the falling speed of the game ball can be reduced. As a result, the staying time of the game balls on the game board can be lengthened.

Also, since the falling speed of the game ball is reduced by the first deceleration guide means, it is possible to prevent the game ball from violently bouncing in all directions when hitting the center display portion. Thereby, the game ball can be reliably guided to the cradle along the center display section.

The first deceleration guide means is preferably a nail that is conventionally driven into a game board, but is not necessarily limited to a nail, and may be an elastic body such as synthetic resin or rubber, a windmill, or the like. .

According to a fourth aspect of the present invention, in the pachinko machine, second deceleration guide means for returning the game balls to the pedestal at a predetermined probability is provided downstream of the pedestal.

Next, the operation and effect of the pachinko machine according to the fourth aspect will be described.

A second deceleration guide means is provided downstream of the cradle. For example, a game ball dropped from the cradle hits the second deceleration guide means and is returned to the cradle with a predetermined probability depending on the angle at which the ball hits. Further, the launched game ball directly hits the second deceleration guide means and is returned to the cradle with a predetermined probability. Thereby, the staying time of the game ball on the game board can be lengthened.

The falling speed of the game balls can be reduced by the game balls that have fallen freely from the downstream end of the cradle hit the second deceleration guide means. This allows
The staying time of the game ball on the game board can be extended.

The second deceleration guide means is preferably a nail which is conventionally driven into a game board, but is not necessarily limited to a nail, and may be an elastic body such as synthetic resin or rubber, a windmill or the like. .

On the other hand, an upper tank 62 for storing prize balls is provided at the upper portion on the rear side of the front frame 12, and the prize balls are communicated with the upper tank 62 at a lower portion of the upper tank 62. A lower tank 66 for guiding to the prize ball payout device 64 is attached.

Next, the main part of the present invention will be described in detail.

As shown in FIGS. 3 and 4, on the upper part of the variable display device 40, which is the center display portion, a pair of slides 72L on which the hit game balls M (see FIG. 5) hit,
72R are provided. This slide 72L, 72R
Is formed so as to have a steep slope from the upstream end to the downstream end.

In this embodiment, the upstream side means the upper side of the game section 38, and the downstream side means the lower side of the game section 38.

At the downstream end of each of the slides 72L, 72R, there are provided receiving bases 74L, 74R.

The receiving bases 74L and 74R are provided with collision portions 76L and 76R where the game balls M collide, and collision portions 76L and 76R.
It is composed of vertical portions 78L and 78R connected to R,
The receiving bases 74L and 74R are formed in an L-shape as a whole.

The collision portions 76L and 76R are gently inclined downward from the center of the game portion 38 to the outside at an inclination angle of 4 ° to 8 ° with respect to the horizontal line L. The vertical portions 78L, 78R are formed by being bent substantially perpendicularly to the collision portions 76L, 76R.

The receiving bases 74L and 74R are AB
It is preferable to be made of a synthetic resin such as S and polycarbonate. When the receiving bases 74L and 74R are made of ABS synthetic resin, it is desirable that the surfaces thereof are subjected to a treatment such as plating for the reason of appearance. As described above, since the receiving bases 74L and 74R are made of synthetic resin, a sufficient coefficient of restitution can be obtained, and when the game ball M is hit, the game ball M is moved to the upstream side of the game section 38. You can bounce back vigorously.

The gaming section 38 located on the upstream side of the receiving tables 74L and 74R has first deceleration nails 80L and 80R.
Three (first deceleration guide means) are driven. For this reason, the game ball M fired is the first deceleration nail 80L, 8
The vehicle is decelerated by hitting 0R, flows down by its inertia, and hits the slides 72L, 72R or the receivers 74L, 74R of the center display unit 40.

Further, the game section 38 located downstream of the receiving tables 74L and 74R has second deceleration nails 82L and 82L.
Two R (second deceleration guide means) are driven. The launched game ball M is decelerated by hitting the second deceleration nails 82L, 82R, and again with a predetermined probability, the cradle 74L,
Returned to 74R.

The number of the first deceleration nails 80L, 80R or the second deceleration nails 82L, 82R is not limited to two or three, but may be four or more.

In this embodiment, the deceleration nails 80L, 80R, 82L and 82R are used as the deceleration guide means. However, the present invention is not limited to this. What is necessary is just to slow down.

As the deceleration guide means, for example, a prize winning tool such as a windmill may be arranged.

Next, the operation and effects of the pachinko machine 10 according to the present invention will be described.

The following functions and effects will be described with respect to the game ball M
Will be described on the left side of the center display section 40.

The game ball M fired by the player operating the operation grip 60 is guided to the guide rail 36 and to the game section 38.

The game balls M guided to the game section 38 fall to the downstream side while hitting a plurality of game nails 70 driven into the game board 34.

Eventually, the game ball M becomes the first deceleration nail 80.
Hit L. Thereby, the falling speed of the game ball M is reduced.

Game ball M hit by first deceleration nail 80L
Bounces again upstream or collides with the slide 72L of the center display unit 40. Thus, the game ball M
Is caused to collide with the first deceleration nail 80L to reduce the falling speed of the game ball M, so that the game ball M staying on the board can be lengthened.

In the present embodiment, as shown in FIG. 4, four game nails 70A, 70B, 70C and 70D are arranged along the slope of the slide 72L.
These further reduce the speed of the game ball M decelerated by the collision with the first deceleration nail 80L, prevent the game ball M from flowing down from the slide 72L formed on a relatively steep slope, and reduce the speed of the slide 72L. A gaming nail 70D at the most downstream position along the slope and a first deceleration nail 80 at the rightmost position
By adjusting with LB, the falling position of the game ball M flowing down, for example, the falling position to the collision portion 76L, the collision position (angle) to the first deceleration nail 80LC at the most downstream position, the second deceleration This is for changing the collision position (angle) with the nail 82L.

For example, each of the first deceleration nail 80LA and the first deceleration nail 80LB is slightly leftward (arrow X in FIG. 4).
Direction), the first deceleration nail 80LA is tilted downward (in the direction of arrow Y in FIG. 4), and the first deceleration nail 80L is tilted downward.
B is inclined upward (in the direction of arrow Z in FIG. 4) to reduce the distance between the first deceleration nail 80LA and the first deceleration nail 80LB. As a result, the game ball M having collided with the first deceleration nail 80LA or the first deceleration nail 80LB is moved to the first deceleration nail 8LA.
Since it is guided between the 0LB and the game nail 70D, it collides not on the downstream side of the collision portion 76L of the cradle 74L, but on the upstream side (center display portion 40 side). Therefore, the game ball M
Collides with the collision part 76L on the upstream side, and
, The game ball M stays on the board for a longer time. Also, when the game ball M rolls on the collision portion 76L on the cradle 74L, it rolls for a relatively long time and is sufficiently decelerated.

It should be noted that the game ball M is the first deceleration nail 80LA
Also, when passing between the first deceleration nail 80LB and the first deceleration nail 80LB, the distance between the first deceleration nail 80LA and the first deceleration nail 80LB is set relatively small as described above. 1
The first deceleration nail 80LA and the first deceleration nail 80LB may come into contact with the game ball M. If contact is made, the falling speed of the game M can be reduced by friction, and the game ball M can stay on the board longer.

Here, the four game nails 70A, 70
B, 70C, and 70D have extremely important functions, but in order to realize them, only the most downstream position of the four game nails is constituted by the game nails 70D, while three game nails are excluded. Even if the configuration of 70A, 70B, 70C is made of a material having elasticity (for example, an elastic body such as a synthetic resin or rubber) instead of a nail, the deceleration of the game ball M and the game ball M
Can be easily realized.

More preferably, four game nails 70A, 7
Two game nails 70 in the middle position among 0B, 70C and 70D
B and 70C are omitted, and the above-mentioned elastic body is formed into an endless belt shape (not shown) to form the game nails 70A at the upper and lower ends.
By crossing over 70D, the same effect as described above can be obtained with a simple configuration.

Next, as shown in FIG. 5, the game ball M colliding with the first deceleration nail 80L and rebounding to the upstream side begins to fall shortly and hits the collision portion 76L of the receiving base 74L. The game ball M that has hit the collision portion 76L rebounds upstream of the game portion 38. As a result, the game ball M staying on the board can be lengthened. In particular, since the cradle 74L is made of a synthetic resin, the game ball M rebounds far upstream of the game section 38.

Here, the collision portion 76L of the cradle 74L is
The game ball M does not stop on the collision portion 76L because it is gently inclined downward from the center of the board to the outside. Particularly, by setting the inclination angle of the collision portion 76L to 4 ° or more with respect to the horizontal line L, the game ball M
There is no stop on L.

If the angle of inclination of the collision portion 76L is less than 4 °, it is not preferable because the game ball M may stay on the collision portion 76L. The falling speed of the ball M is undesirably accelerated.

Next, as shown in FIG. 6, the game ball M rolled on the collision portion 76L of the cradle 74L falls from the downstream end of the collision portion 76L. Here, since the receiving base 74L has a relatively large surface area, the contact area with the game ball M is increased, and the game ball M can be surely decelerated by the frictional force generated therebetween. The game ball M dropped from the downstream end of the collision portion 76L collides with the second deceleration nail 82L. The game ball M that has collided with the second deceleration nail 82L bounces upstream or returns again to the collision portion 76L of the cradle 74L depending on the collision angle. And cradle 7
The game ball M that has collided with the 4L collision portion 76L rebounds further upstream of the game portion 38. As a result, the number of times the game ball M reciprocates on the path between the cradle 74L and the second deceleration nail 82L increases, and the newly launched game ball and the previously launched game ball are simultaneously Since they are mixed in the cradle 74L, the player can get the impression that the game balls fly near the cradle 74L through the visual sense, and can lengthen the game ball M staying on the board.

Here, for example, the first deceleration nail 80LC
By setting the interval between the second deceleration nail 82LB and the second deceleration nail 82LB to be small, the game ball M dropped from the downstream end of the collision portion 76L of the cradle 74L can receive the first deceleration nail 80LC or the second deceleration nail 80LB. The probability of collision with the nail 82LB increases. Therefore, the game ball M can be returned to the collision portion 76L again, and the falling speed of the game ball M can be reduced.

By setting the distance between the second deceleration nail 82LA and the second deceleration nail 82LB to be small, the distance between the first deceleration nail 80LC and the second deceleration nail 82LB is reduced. Game ball M that has been moved is the second deceleration nail 82LA or the second deceleration nail 82LA.
Is more likely to collide with the deceleration nail 82LB. Therefore, the game ball M can be returned to the collision portion 76L again, and the falling speed of the game ball M can be reduced.

The game ball M that has dropped to the downstream side of the second deceleration nail 82L enters the variable winning device 42 or the starting port 44, and finally enters the out port 52.

The same operation and effect can be obtained even when the game ball M enters the right side of the center display section 40.

That is, the game ball M is moved to the first deceleration nail 80
By decelerating by hitting the R, the cradle 74R and the second deceleration nail 82R, the game ball M can stay on the board for a longer time.

As described above, according to the pachinko machine 10 of the present invention, the game ball M is provided with the first deceleration nails 80L, 80L.
0R, cradle 74L, 74R and second deceleration nail 82
By hitting L and 82R, the falling speed of the game ball M is reduced, and the game ball M staying on the board can be lengthened.

For this reason, 4 to 5 game balls M always stay in the game section 38, and the game balls M do not win the prize port 46 or the start port 44 somewhere. You can have a sense of expectation.

Also, the game ball M is set to the first deceleration nail 80L,
80R, cradle 74L, 74R and second deceleration nail 82
By hitting L and 82R, the initial velocity of the free fall of the game ball M can be made uniform, so that the adjustment of the game nail 70 provided further downstream is facilitated.

Further, without particularly reducing the size of the center display section 40 and without complicating the structure of the center display section 40, the game balls M can be viewed to the extent that the player can visually see the falling game balls M. Can be reduced, and the game ball M can be left in the game section 38 of the game board 34 for a long time.

Further, the first deceleration nails 80L, 80R,
Cradles 74L, 74R and second deceleration nails 82L, 82
Since the R is provided on both the left and right sides of the center display section 40, even when the game ball M enters the right side of the center display section 40, the fall speed is substantially the same as that when the game ball M enters the left side or at a lower drop speed. Therefore, the winning number is less likely to change, and the starting adjustment and the like are not complicated.

The first deceleration nails 80L, 80L
R, the second deceleration nails 82L, 82R and the cradle 74L,
The configuration of the 74R is preferably located as far upstream of the gaming section 38 as possible, thereby increasing the player's expectation of the possibility that the gaming ball M will win.

[0081]

According to the pachinko machine of the present invention, by providing the center display with the cradle on which the game ball collides,
While avoiding downsizing and complication of the center display,
It is possible to surely decelerate the game ball and prolong the time that the game ball stays on the board.
