Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine such as a pachinko machine.

[0002]

2. Description of the Related Art Conventionally, in a ball game machine such as a pachinko machine,
A launch rail for launching a game ball and a guide rail for guiding the game ball launched from this launch rail to the upper side of the game board are provided, and the launch rail and the guide rail are spaced from each other in the longitudinal direction of the launch rail. The ball return passage is provided below the guide rail and the launch rail to return the game ball that has stalled in the middle of the guide rail to the lower plate side.

When the game ball is launched, the game ball on the launch rail is struck with a hammer, and the inertial force causes the game ball to pass above the ball return passage from the launch rail to the lower side of the guide rail. After flying, guide along the guide rail to the upper side of the game board, and the game ball that stalls in the middle of the guide rail returns downward along the guide rail,
The ball is returned from the guide rail to the launch rail to the lower tray through the ball return passage.

[0004]

In the conventional ball-and-ball game machine, a ball return passage is provided below the launch rail and the guide rail, and the game ball stalled in the middle of the guide rail is moved to the lower end side of the guide rail. Since I am trying to guide and return from the ball return passage to the ball, to ensure the transfer of the game ball from the launch rail to the guide rail and also to guide the stalled game ball to the ball return passage, It is necessary to secure a large interval in the longitudinal direction of the launch rail, gently bend the lower side of the guide rail, and arrange the guide rail largely below the extension line of the launch rail.

However, if the lower side of the guide rail is arranged below the extension line of the launch rail, the game ball launched from the launch rail jumps above the ball return passage by inertial force and passes above the ball return passage. Then, when it comes into contact with the lower end side of the guide rail, a very large impact is received from the guide rail. Therefore, when the game ball is transferred from the launch rail to the guide rail side, the inertial force of the game ball is greatly diminished by the impact, and there is a drawback that a mistaken launch of the game ball that stalls in the middle of the guide rail is likely to occur.

In view of such conventional problems, the present invention is configured to return a game ball that has stalled in the middle of the guide rail from the upper side of the guide rail to reduce the impact when the game ball transfers to the guide rail, You can reduce the stall of the game ball in the middle of the guide rail, you can guide the game ball along the guide rail to the upper side of the game board in a stable state, and even if the game ball stalls in the middle of the guide rail Also, it is an object of the present invention to provide a ball game machine capable of smoothly and reliably returning the game ball to the lower plate side.

Next, the operation of the pachinko machine having the above structure will be described. At the start of the game, when the game balls are put in the upper plate 6 and the operation handle 10 is turned, the launching device 9 is activated, and the game balls are supplied from the upper plate 6 onto the launch rails 18 one by one.
This game ball is launched along the launch rail 18 by the impact of the impact mallet 19. The game ball hit by the hitting mallet 19 usually reaches the upper side of the game board 5 via the launch rail 18 and the guide rail 11 and then falls downward while hitting an obstacle nail or the like along the game board 5. Enter the prize hole 14 etc. or the lower out mouth.

When the game ball moves from the launch rail 18 to the guide rail 11, the tip end side of the launch rail 18 and the lower end side of the guide rail 11 are arranged adjacent to each other, so that they are separated from the launch rail 18. The game ball is immediately supported by the guide rail 11. Therefore, when the game ball comes into contact with the guide rail 11, it moves smoothly with little impact.

The game ball after the launch is the guide rail 11
When moving upward along the guide member 24 and abutting against the lower side of the guide member 24, the bending portion 34 bends so that the free end side of the guide member 24 is lifted, and the game ball passes above the guide member 24. . If the game ball passes above the guide member 24, the guide member
The free end side of 24 descends due to the elastic return of the bending portion 34 and contacts the upper surface of the guide rail 11.

When the game ball further rises and moves to the upper end of the passage 12, the game ball passes along the guide rail 11 and between the ball return prevention member 36 without contacting the ball return prevention member 36. Go. Therefore, on the upper end side of the passage 12, the game ball is smoothly guided without receiving resistance.

The game ball flies from the upper end of the guide rail 11 to the upper side of the game board 5 and hits an obstacle nail or the like. At this time, even if the game ball hitting an obstacle nail or the like bounces back toward the passage 12 side, the ball return prevention member 36 is arranged inside the guide rail 11 with a gap k slightly larger than the diameter of the game ball. Therefore, there is almost no possibility that the game ball will return to the passage 12 side between the guide rail 11 and the ball return prevention member 36.

If the game ball passing above the guide member 24 stalls in the middle of the guide rail 11 due to lack of striking force or the like, it returns downward along the guide rail 11 and moves from the guide rail 11 to the guide member 24. It passes through the free end side, passes through the upper surface of the guide portion 33, and is guided to the front surface side of the ball return port 23. And
This game ball is a ball return port 23 by the ball guiding portion 28 of the mounting member 25.
It is guided to and goes back to the lower plate 8 side.

According to the construction of this embodiment, the game ball is placed in the lower plate.
A ball return port 23 that returns to the 8 side, and a guide member 24 that guides the game ball that has stalled in the middle of the guide rail 11 to the ball return port 23 side,
It is provided on the upper side of the guide rail 11 and at the lower part of the game board 5, and is designed to return from the upper side of the guide rail 11 to the lower plate 8 side through the guide member 24 and the ball return port 23, so that the launch rail 18 It is not necessary to provide a large gap between the guide rail 11 and the lower end side of the guide rail 11 so that the lower end side of the guide rail 11 is below the extension line of the firing rail 18.

Therefore, the lower end side of the guide rail 11 is arranged adjacent to the firing rail 18 so that the lower ends of the guide member 24 and the guide rail 11 are substantially aligned with the extension line of the firing rail 18. Is possible and firing rail 18
The game ball shot from the launch rail 18 to the guide rail 11
It is possible to mitigate the impact when moving to the lower end side of the game ball, reduce the stall of the game ball in the middle of the guide rail 11, and guide the game ball to the upper side of the game board 5 in a stable state.

Particularly, by arranging the lower end side of the guide rail 11 adjacent to the launch rail 18 so that the lower end sides of the guide member 24 and the guide rail 11 are substantially aligned with the extension line of the launch rail 18, the launch rail 18 is arranged. The movement of the game ball from the guide rail 11 side can be made very smooth, the length of the launch rail 18 can be lengthened, or a linear portion can be provided on the lower end side of the guide rail 11 so that a stable state can be obtained. You can guide the game ball at.

Therefore, from the launch rail 18 to the guide rail
The game ball can be smoothly and surely launched to the upper side of the game board 5 via 11 and the launch rail 18 and the guide rail.
Since the game ball can be guided to the upper side of the game board 5 with the inertial force of the game ball in the middle of 1 being reduced as much as possible, the flight from the upper end of the guide rail 11 to the upper side of the game board 5 is performed. Variations in flight distance and flight trajectory of the game balls are reduced.

Further, even if the game ball stalls in the middle of the guide rail 11, the game ball is moved to the guide rail.

The guide member 24 has one end side attached to the game board 5 side, and the other free end side is placed on the upper surface of the guide rail 11, and the free end side swings vertically. Since the bending portion 34 is provided in the middle part of the guide member 24, even though the structure of the guide member 24 is very simple, when the game ball passes through the guide member 24, the bending portion 34 It is possible to pass the game ball to the upper side of the guide member 24 without reducing the inertial force of the game ball by bending, and if the game ball stalls in the middle of the guide rail 11 after the passage, the game ball is The free end side of the guide member 24 can be reliably rescued from the guide rail 11 side and guided to the ball return port 23 side.

Further, since there is a bending portion 34 in the middle of the guide member 24 and the other end side of the guide member 24 is divided into a plurality of scooping pieces 35 by slits, the game ball passes through the guide member 24. Sometimes the free end side is easily bent, and the inertial force of the game ball due to the frictional resistance of the guide member 24 can be suppressed as much as possible,
It is possible to prevent the game ball from stalling.

In addition, when the guide member 24 is damaged or deformed, the guide member 24 is detachably attached to the attaching member 25. Therefore, only the guide member 24 should be removed and replaced with a new one. We can respond quickly and easily. Further, since the mounting member 25 is provided with a ball guiding portion 28 for guiding the game ball guided by the guide member 24 to the ball return port 23, the game ball guided to the front side of the ball return port 23 by the guide member 24 is provided. The ball guiding portion 28 can reliably guide the ball to the ball return port 23.

At the tip of the passage 12, the ball return prevention member 36 is arranged inside the guide rail 11 with a gap k slightly larger than the diameter of the game ball, so that the game ball is a guide rail.
It is possible to pass between the ball 11 and the ball return preventing member 36 along the guide rail 11 without contacting the ball return preventing member 36. Therefore, on the lower side of the guide rail 11, the game ball is a guide member.
Even if some frictional resistance occurs when lifting the free end side of 24, there is no resistance at the top side, so the stall of the game ball is suppressed as much as possible while preventing the game ball from returning to the passage 12 side. It is possible to smoothly guide the game ball along the guide rail 11.

The guide member 24 has a mounting hole 42 on the base side, and is pivotally attached in a vertically swingable and detachable manner by a front and rear pivot shaft 43 inserted into the mounting hole 42. The pivot 43 has a halved shape projecting forward from the mounting member 25 and is integrally formed with the mounting member 25. A retaining portion 44 is formed at the tip of the pivot shaft 43. Also in the case of this embodiment, it can be carried out in the same manner as the first embodiment.

10 and 11 show a third embodiment of the present invention, in which a driving means 45 for raising the free end side of the guide member 24 in association with the firing of the game ball is provided. Drive means 45
The solenoid is used for, and is arranged vertically on the back side of the game board 5 below the ball return port 23.
