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, an arrangement ball machine, and the like, and to an improvement in a passage structure of a ball return passage for returning a return ball stalled in the middle of a guide rail to a lower plate side. It is.

[0002]

2. Description of the Related Art Conventionally, in a ball game machine such as an arrange ball machine, a ball return path is provided between a launch rail and a guide rail, and when a game ball stalls in the middle of the guide rail due to insufficient hitting force or the like, The return ball descending along the guide rail is returned to the lower plate via the ball return passage. This ball return passage has conventionally been disclosed in Japanese Patent Laid-Open No. 8-182812.
As disclosed in Japanese Patent Application Laid-Open Publication No. H11-157, a ball receiving member is provided below the firing rail, and an inclined guide portion that is inclined along the flight direction of the return ball returning from the guide rail at the tip of the ball receiving member on the guide rail side. The arc guide portion facing the inclined guide portion is formed in an arc shape along the flight direction of the return ball, and the inclined guide portion and the arc guide portion are arranged closer to the left and right to return the ball. An entrance portion of the passage is formed, and a lower bent passage portion is formed at the entrance portion.

[0003]

In the conventional structure of the ball return passage, the inclined guide portion and the arc guide portion are arranged close to each other on the left and right, and the entrance side of the ball return passage is connected to the return ball from the guide rail. The return ball can be smoothly returned to the lower plate via the ball return path if there are only one return ball because it is configured to be narrow along the flight direction of the ball. When the collisions occur at the entrance side of the return passage, there is a problem that the return ball collects at the entrance side of the ball return passage, and there is a drawback that the return ball cannot be smoothly and reliably returned to the lower plate.

That is, in the conventional passage structure, if a firing mistake occurs in which a game ball stalls in the middle of the guide rail, and immediately after that, the firing of the subsequent game ball is stopped, the subsequent ball is stopped at the entrance side of the ball return passage. Since there is no collision with the game ball, the return ball enters the ball return passage through the space between the inclined guide and the arc guide while drawing a predetermined flight trajectory from the tip of the guide rail. It is possible to smoothly return from the return passage to the lower plate. However, if the return ball collides with the subsequent game ball due to a delay in stopping the launch of the subsequent game ball, a plurality of game balls become return balls and concentrate on the entrance side of the ball return path. There is a problem that the returning ball cannot enter the ball returning passage while drawing a predetermined flight trajectory, and stays at the entrance side of the ball returning passage.

In particular, in the current ball game machine which employs an electric firing means for driving a hammer by a firing motor, the interval between firing of game balls is very short, and a large number of game balls are fired in a short time. Once a firing error occurs in which the game ball stalls in the middle of the rail, a plurality of firing errors are likely to continue in succession. Therefore, if a firing mistake continues, how to promptly guide the return ball to the ball return path and eliminate the ball return ball from the launch path of the game ball including the launch rail and the guide rail, It is very important for the game to proceed quickly. The present invention has been made in view of such a conventional problem, even when a plurality of return balls are continuously generated,
It is an object of the present invention to provide a ball game machine capable of smoothly and surely inserting the return ball into the entrance side of the ball return passage and immediately removing the return ball out of the launch path of the game ball.

A mounting portion 51 having a mounting hole 50 is formed in the passage forming member 37 on the bending portion side of the bending passage portion 36. Then, the passage forming member 37 fits the fitting portion 43 into the boss portion 45 of the fixing plate 8 and
With the bosses 52 of the fixing plate 8 in contact with each other.
It is removably mounted on the fixing plate 8 by mounting screws 53, 54 screwed into 5, 52. The back guide passage 34 is vertically mounted on the back side of the front frame 2 to connect the bent passage portion 36 of the passage forming member 37 and the lower tray gutter 55 as shown in FIG.
The lower tray gutter 55 is for guiding the game balls overflowing from the upper plate 12 to the lower plate 9 when the upper plate 12 is full, and
2 is attached to the back side.

In the above-structured ball game machine, when the operation handle 23 of the firing means 11 is turned while the game ball is placed in the upper plate 12, the firing means 11 is operated to move the upper surface of the upper plate 12 onto the firing rail 13. The supplied game ball is hit with a hitting hammer 21 and the game ball is fired along the guide rail 15 toward the upper side of the game board 5. The game ball hit by the hammer 21 is normally guided from the launch rail 13 to the guide rail 15, reaches the upper side of the game board 5 via the guide rail 15, and then gets along with the obstacle nail along the game board 5. It falls down along the board surface while hitting etc. Then, the game ball wins the prize means or the like during the fall, or is collected from the lower out ball port to the back side of the game board.

Further, the guide rail 15 is not used due to insufficient hitting force or the like.
The game ball that has stalled on the way back returns along the guide rail 15 and flies from the lower end of the guide rail 15 to the firing rail 13 in the direction indicated by the arrow a. After colliding with a vertical guide portion 33 formed substantially perpendicular to the end face of the member 31, the vertical guide portion 33 reflects toward the inclined bottom wall portion 39 in the direction of arrow b and enters the opening space. For this reason, the return ball returning to the vertical guide portion 33 side from the tip side along the guide rail 15 immediately enters the opening space 35 on the entrance side of the ball return passage 20,
It can be quickly eliminated from the launch path of the game ball from the launch rail 13 to the guide rail 15.

When the game ball stalls on the upper end side of the guide rail 15 and the return ball is in the middle of the guide rail 15 without entering the opening space 35, the subsequent game ball is moved from the firing rail 13 side. When fired sequentially, a plurality of return balls may collide and stay on the guide rail 15. In this case, if the launch of the subsequent game ball is interrupted, the plurality of return balls return in the direction indicated by the arrow a from the tip end of the guide rail 15 in a state where the plurality of return balls are continuous in a line or close to that. However, the opening space on the entrance side of the ball return passage 20
Since 35 has a volume enough to accommodate a plurality of return balls, each return ball flies from the tip of the guide rail 15 to the firing rail 13 in the direction indicated by the arrow a, as described above. The ball can be guided to the opening space 35 while sequentially colliding with and reflecting on the vertical guide portion 33 of the ball receiving member 31.

Therefore, a plurality of return balls do not accumulate between the launch rail 13 and the guide rail 15, and each return ball is reflected by the vertical guide portion 33, and a game from the launch rail 13 to the guide rail 15 is performed. The ball can be immediately removed from the firing path. As a result, even if a firing error occurs such that a plurality of return balls are formed due to the stall of the game ball at the upper end side of the guide rail 15, the firing operation of the subsequent game ball by the firing means 11 is stopped for a short time. If so, a plurality of return balls on the guide rail 15 can be smoothly and promptly removed from the launch path, and the launch of the game balls can be resumed immediately.

The return ball reflected by the vertical guide portion 33 and entering the opening space 35 usually falls from the vertical guide portion 33 onto the inclined bottom wall portion 39, and follows the inclination of the inclined bottom wall portion 39. Direct bending passage
It moves in the direction indicated by the arrow c to the side of 36, or moves to the bent passage portion 36 after hitting the vertical side wall portion 40 from the inclined bottom wall portion 39. Therefore, even when the return ball collides with the vertical guide portion 33 by impact, it can be reliably guided from the vertical guide portion 33 to the bent passage portion 36 side via the inclined bottom wall portion 39.

When a plurality of return spheres enter the opening space 35 in a short time, the return sphere on the inclined bottom wall portion 39 or the opening space 35
The subsequent return spheres may collide with the return spheres and the like that are reflected inside and jump up from the inclined bottom wall portion 39, and each return sphere may move in the opening space 35 while changing irregularly. At this time, even if there is a return ball that jumps up sharply in the direction indicated by the arrow d from the inclined bottom wall portion 39 toward the vertical side wall portion 40 or the inclined side wall portion 41 toward the upper side, the vertical side wall portion 40 is not guided by the guide rail 15. Receding from the front end side, there is an inclined side wall portion 41 between the vertical side wall portion 40 and the guide rail 15, so that it is reflected on the inclined bottom wall portion 39 and collides with the vertical side wall portion 40, the inclined side wall portion 41, etc. It is possible to prevent the return sphere from rising along these and jumping upward from the opening space 35 as much as possible. That is, it is possible to prevent the return ball from jumping out of the opening space 35 on the tip side of the inclined side wall 41 and the guide rail 15.

Further, since the vertical side wall portion 40 retreats from the front end side of the guide rail 15, and the inclined side wall portion 41 exists between the vertical side wall portion 40 and the guide rail 15, the firing rail 13 and the guide rail
While reducing the distance from the space 15, the volume of the opening space 35 can be increased, a large number of return spheres can be temporarily accommodated in the opening space 35, and the return sphere that has collided and reflected in the opening space 35 rises Can be prevented as much as possible. The return sphere in the opening space 35 is
It is guided from the horizontal part of the bent passage part 36 to the back guide passage 34 via the vertical part, and is returned from the back guide passage 34 to the lower plate 9 via the lower plate gutter 55. Then, the return ball is bent 36
, The return ball detection switch 38 detects the return ball.

The return ball hit by the vertical guide portion 33 on the end face of the ball receiving member 31 is reflected by the vertical guide portion 33 and collides with the inclined bottom wall portion 39. Bending passage part 36
Since the upper wall portion 42a and the inclined bottom wall portion 39 are integrally connected by the connecting portion 46, the inclined bottom wall portion 39 is reinforced by the upper wall portion 42a and the connecting portion 46. The strength and durability of the inclined bottom wall 39 are improved. Also, the inclined bottom wall 39,
The vertical side wall 40, the inclined side wall 41, the bent passage 36, etc.
Since the passage forming member 37 is integrated through the 44 and the passage forming member 37 is mounted on the front side of the fixing plate 8, the number of parts can be reduced and the mounting thereof can be facilitated. Further, since the bent passage portion 36 is formed in an inverted L shape from one end side to the other end side of the inclined bottom wall portion 39, the passage forming member 37
Can be downsized.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment.
For example, in the embodiment, the passage forming member 37 in which the inclined bottom wall portion 39, the vertical side wall portion 40, the inclined side wall portion 41, the bent passage portion 36, and the like are integrally formed through the front wall portion 44 is used. The passage forming member 37 may be divided vertically into two. Further, the shapes and structures of the respective portions such as the inclined bottom wall portion 39, the vertical side wall portion 40, the inclined side wall portion 41, and the bent passage portion 36 can be appropriately changed without departing from the spirit of the present invention. The inclined side wall portion 41 and the return ball detection switch 38 may be omitted. Further, it goes without saying that the present invention can be widely applied to not only pachinko machines but also arrange ball machines, sparrow ball machines, and other various ball game machines.
