Description

[Detailed description of the invention] <Industrial field of application> The present invention causes a predetermined number of prize balls ejected by a prize ball ejecting device to collide with a bell to generate a sound effect,
This invention relates to a structure of a prize ball flow path of a pachinko machine, in which prize balls are guided to an upper supply tray, and when the upper supply tray is full of prize balls, they overflow to a lower tray.

<Prior art> When the upper supply tray becomes full of prize balls and the prize balls are further discharged, the prize balls become clogged in the prize ball discharge gutter, causing problems such as the prize ball ejecting device not operating properly. Trouble occurs. For this reason, conventionally, a treadle on which the prize ball is placed is rotatably provided in the middle of the prize ball discharge gutter.
When a prize ball that has become jammed is placed on the treadle, the flow path of the prize ball is switched by a switching valve that is activated, or a shutter member is provided in the flow path that communicates from the upper supply tray to the lower receiving tray to prevent jamming. The prize balls that came in activated the shutter member, causing the falling prize balls to overflow into the lower tray.

<Problems to be solved by the invention> However, the conventional prize ball flow path described above,
The structure was complex, resulting in unstable operating conditions and a high failure rate. In addition, in a prize ball flow path that does not use a switching valve or shutter member, the prize balls whose flow direction is disturbed by hitting the bell are directly discharged into the lower tray, even though the upper supply tray is not full. There was an inconvenience. In particular, in the prize ball flow path where the prize ball strongly collides with the bell to generate a loud sound effect, the flow direction of the prize ball that hits the bell is greatly disturbed in the horizontal direction. The above-mentioned inconveniences were likely to occur. Furthermore,
Since this bell largely protrudes into the ball flow downstream path and reduces the effective flow cross-sectional area of the downstream path, troubles have occurred in which prize balls that have hit the bell and spread out become clogged.

<Means for solving the problem> The present invention was proposed in view of the above, and includes a bell facing the lower end of the prize ball discharge gutter, and a side surface of the prize ball discharge gutter facing the circumferential surface of the bell. In addition to forming a bulge so as not to reduce the effective cross-sectional area of the flow path,
A ball guide part is formed in the lower part of the bulging part to prevent the winning ball that hits the bell from directly flowing into the second connection gutter and causes it to fall into the branching chamber, and the ball guide part is configured to branch from the second connection gutter. At the connection part with the chamber, a control wall is formed with the bottom of the branch chamber standing upright, and is positioned below the ball guide part and closer to the second connection gutter.

<Function> The prize ball ejected by the prize ball ejecting device flows down inside the prize ball ejection gutter and hits the bell, producing a sound effect, and even if the flowing direction is greatly disturbed laterally at this time,
This prize ball hits the ball guide part and is forced to flow downward, and remains in the branching chamber by the control wall. Therefore, some of the predetermined number of prize balls will not fall directly into the second connection gutter and be discharged into the lower tray. In addition, since the effective cross-sectional area of the flow path in the portion facing the bell does not become smaller due to the formation of the bulge at a position facing the circumferential surface of the bell, the diffusion occurs when it hits the bell in this portion. The prize balls will never get stuck.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

A pachinko machine 1 configured to eject prize balls when a batted ball wins a prize has an upper supply tray 3 into which balls fired by a batted ball launcher 2 are fed, and a lower tray 4 for storing balls on the front. , a storage tank 5 in which a large number of prize balls are stored on the back side, a prize ball discharge device 6 that discharges the balls guided from the storage tank 5 to a predetermined number of balls each time a batted ball wins a prize, and a prize ball discharge device 6. Device 6
A prize ball discharge gutter 7 and the like extending downward from the prize ball discharge gutter 7 is provided, and a branch chamber 9 having a bottom portion 8 is formed at the lower end of the prize ball discharge gutter 7.
0 is extended and connected to the upper supply tray 3,
A second connecting gutter 11 extends from the other side of the branching chamber 9 and is connected to the lower tray 4. A bell 12 that generates a sound effect when a falling winning ball hits the upper part of the above-mentioned branching chamber 9 faces, and a bulging part 7a is formed on the side surface of the winning ball discharge gutter 7 facing the circumferential surface of the bell 12. The effective channel cross-sectional area of the prize ball discharge gutter 7, that is, the area in which the prize balls can flow down, is configured so as not to decrease, and the flow direction of the prize balls flowing down is rectified downward below the bulging portion 7a. The ball guide portion 7b is formed substantially vertically. The bottom part 8 of the branching chamber 9 is gently sloped downward toward the inlet 13 of the first connection gutter 10, and near the boundary with the inlet 14 of the second connection gutter 11, there is a bottom part 8 below the ball guide part 7b. A control wall 15 is disposed near the second connecting gutter 11 and stands upwardly at a height substantially equal to the diameter of the sphere, and is formed over the entire width of the lower end of the inner circumference of the inlet 14. Bottom 1 of the first connection gutter 10
0' is the bottom 8 of the branching chamber 9, as shown in FIG.
from the top toward the upper supply tray 3,
Also, the bottom 1 of the second connecting gutter 11 extending laterally
1' is the control wall 1 described above, as shown in FIG.
It slopes gently downward from the upper end of 5 toward the downstream side, and from the middle, it bends downward and connects to the lower saucer 4. Note that the bottom 11' of the second connection gutter 11
may be extended from the upper end of the control wall 15, as shown in FIG.

The prize ball ejected from the prize ball ejecting device 6 flows down in the prize ball ejection gutter 7 and hits the bell 12 on the way to generate the sound effect of prize ball ejection, which reduces the downward force. It falls into the branching chamber 9. In this case, the winning balls hit by the bell 12 are disturbed in their flowing direction and dispersed, but the flowing direction is rectified almost vertically by the ball guide portion 7b formed at the lower end of the winning ball discharge gutter 7. . Therefore, the winning ball that bounces off the bell 12 does not directly flow into the second connection gutter 11, but falls reliably into the branching chamber 9.
Therefore, the prize balls flowing down in the prize ball discharge gutter 7 are not directly discharged to the lower tray 4 through the second connection gutter 11. In addition, when the prize ball discharged by the prize ball discharge device 6 flows down in the prize ball discharge gutter 7, even if the bell 12 protrudes into the channel, the prize ball is smoothly flowed in this part by the bulging part 7a. Since the effective cross-sectional area of the flow path is ensured for the ball to flow down, the prize ball will not become clogged in this area. The prize ball that has fallen into the branching chamber 9 has its bottom part 8 sloped slightly downward toward the inlet 13 of the first connection gutter 10, and the control wall 15 prevents it from entering the second connection gutter 11. Therefore, it rolls on the bottom part 8, flows into the first connection gutter 10, and is led out to the upper supply tray 3. However, if the balls overflow into the upper supply tray 3 and the prize balls accumulate in the branching chamber 9,
As shown in FIG. 4, from the prize ball discharge gutter 7 to the branch chamber 9
The prize ball that falls inside will land on top of the remaining ball.
When prize balls fall one after another in this state, the prize balls stacked on top of each other in the branching chamber 9 collapse, and as shown in FIG. 4, the prize balls climb over the control wall 15 and overflow. , passes through the second connection gutter 11 and flows out to the lower tray 4. Therefore, even if the upper supply tray 3 is full of balls, the prize ball discharge gutter 7 will not be clogged with prize balls.

Note that, as shown in FIG.
2 and bounces back toward the second connection gutter 11, this winning ball is bounced back by the swinging piece 16 and falls into the branching chamber 9 even more reliably. When the upper supply tray 3 becomes full of prize balls and a large number of prize balls accumulate in the branching chamber 9, the overflowing prize balls cause the swinging piece 16 to rotate as shown by the dotted line in the figure. second
Overflows to the connection gutter 11. Therefore,
The prize ball discharge gutter 7 is not clogged with prize balls. Also,
If the stopper 17 of the swinging piece 16 is provided inside the branching chamber 9, the swinging piece 16 will not rotate into the branching chamber 9, so the prize ball will not be caught between the control wall 15 and the swinging piece 16. do not have.

In addition, the ball guide part 7b in the present invention is the bell 1
The ball is not limited to being formed vertically, as long as it has the function of rectifying the downward direction of the prize ball that bounces off the ball 2 and reliably guides it into the branching chamber 9 and causes it to fall. It may be slightly slanted.

<Effects of the invention> As explained above, according to the invention, a bulge is formed on the side surface of the prize ball discharge gutter facing the circumferential surface of the bell, so that the bell can pass through the flow path in order to generate a loud sound effect. Even if the ball protrudes inward, the effective cross-sectional area of the flow path through which the prize ball flows will not be reduced. Therefore, a loud sound effect is produced when the prize ball hits the bell, and the prize balls that hit the bell and spread out do not get stuck in this part.

In addition, when the prize ball ejected by the prize ball discharge device hits the bell protruding into the channel, a sound effect is generated and the downward force decreases, and the downward direction of the prize ball that bounces off the bell is Even if the ball changes greatly in the lateral direction, the ball guiding section rectifies the downward direction of the prize balls, so that the prize balls will surely fall into the branching chamber. In addition, since the control wall is positioned below the ball guide part and closer to the second connection gutter and is erected, the prize balls that fall into the branching chamber will not directly transfer into the second connection gutter, and the control wall will be ensured. It can be kept in the branch room. Therefore, in a state where no prize balls remain in the branching chamber, the prize balls discharged by the prize ball discharge device are reliably led out to the upper supply tray. When the upper supply tray is full of prize balls and the prize balls stay in the branching chamber, only the overflowing balls smoothly overflow over the control wall and flow out into the lower receiving tray through the second connection gutter. Therefore, there is no chance of ball clogging.

In addition, the present invention has a simple structure, has a small number of parts, is easy to assemble, and has an extremely low failure rate, making it extremely practical.
