Abstract

PURPOSE:To prevent balls from being stopped by making a flow of balls in a ball saucer smooth. CONSTITUTION:A difference in step section 16 is provided between an upstream side slope 14 and a downstream side slope 15 on the bottom of a ball saucer 13 and the downstream side slope 15 is lower than the upstream side slope 14 by one step by the difference in step section 16. Further, the downstream side slope 15 is provided with a ball ordering section 17 of which path is gradually narrowed toward the downstream side (right side), thereby ordering PACHINKO balls to finally one line. In this case, since the downstream side slope 15 is lower than the upstream side slope 14 by one step by the difference in step section 16, a flow of balls from the upstream side slope 14 to the downstream side slope 15 gains strength and a bridge of the balls on the downstream side slope 15 is broken by a force of the flow of the balls, so that the balls smoothly flow on the downstream side slope 15. Thus, the balls smoothly flow from an outflow port 18 to a rectifier while sequentially lining in one line along the ball ordering section 17.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball receiving tray of a pachinko machine for receiving pachinko balls discharged as prize balls.

[0002]

2. Description of the Related Art As is well known, as shown in FIG. 4, in the lower part of the front surface of a pachinko machine, a ball receiving tray 1 called "upper plate" for receiving pachinko balls discharged as prize balls is provided.
0 is provided. The ball receiving tray 10 is formed such that the bottom surface thereof is inclined downward toward the right side, and the inclination causes a pachinko ball to flow rightward and be supplied to a rectifier (not shown). In this case, since it is necessary to supply the pachinko balls to the rectifier one by one in synchronization with the firing operation of the pachinko balls, the flow path is gradually narrowed in the downstream side portion of the ball tray 10 and finally the pachinko balls are finally made. Are arranged in a line, which is a so-called ball-crushing structure 9.

[0003]

By the way, the ball tray 10
The pachinko balls flowing on the bottom surface of the ball are pushed by the pachinko balls behind them (upstream side) and receive back pressure (hereinafter referred to as "ball pressure"). Will grow larger. For this reason, if the ball tray 10 is dirty or the pachinko balls are not sufficiently polished, and the sling of the pachinko balls is poor, the pachinko balls flowing through the ball collapsing 9 that narrows the flow path bridges due to ball pressure. Occasionally, a ball jam occurs due to the formation of a ball, which hinders the pachinko ball's firing action, which caused the player to feel uncomfortable.

The present invention has been made in view of the above circumstances, and therefore an object thereof is to provide a ball saucer for a pachinko machine capable of improving the ball flow and preventing ball clogging. .

[0005]

In order to achieve the above object, the ball receiving tray of a pachinko machine of the present invention is formed so that a step is formed on the upstream slope of the bottom surface and the downstream slope is lowered. (Claim 1). In this case, the slope of the upstream slope of the bottom surface of the ball tray may be made larger than the slope of the downstream slope (claim 2).

[0006]

The bottom surface of the ball tray according to claim 1 of the present invention has a step between the upstream slope and the downstream slope, and the downstream slope is one step lower than the upstream slope. Therefore, the ball flow from the upstream slope to the downstream slope has momentum, and the momentum of the ball flow breaks the pachinko ball bridge on the downstream slope to improve the ball flow on the downstream slope. In this case, if the slope of the upstream slope is made larger than the slope of the downstream slope, the momentum of the ball flow from the upstream slope to the downstream slope is further increased, and the ball flow is improved. Become.

[0007]

An embodiment of the present invention will be described below with reference to FIG. On the upper left side of the front plate 11 provided at the lower front of the pachinko machine, the prize ball outlet 12 and the prize ball outlet 12 are provided.
There is provided a ball tray 13 for receiving the pachinko balls discharged from. The ball receiving tray 13 has an entire bottom surface inclined so that the pachinko balls flow down toward the outlet 18 at the right end, and the prize ball outlet 12 is located at the uppermost flow portion (left end). A step 16 is provided between the upstream slope 14 and the downstream slope 15 on the bottom surface of the ball tray 13, and the downstream slope 15 is lower than the upstream slope 14 by the step 14. Further, the downstream slope 15 is provided with a ball collapsing 17 that gradually narrows the flow path toward the downstream side (right side) and finally aligns the pachinko balls in a line.
In this embodiment, the slope of the upstream slope 14 is substantially the same as the slope of the downstream slope 15.

The bottom surface of the ball receiving tray 13 of the first embodiment configured as described above is provided with a step 16 between the upstream slope 14 and the downstream slope 15, and the downstream slope 16 is provided by this step 16. Is one step lower than the upstream slope 14. For this reason, the ball flow from the upstream slope 14 to the downstream slope 15 has momentum, and the momentum of the ball flow causes the pachinko ball bridge on the downstream slope 15 to collapse, improving the ball flow on the downstream slope 15. To do. As a result, the ball collapse 17
There is no jamming around the area, and the pachinko balls are lined up in sequence along the ball break 17 and the outlet 1
8 to flow smoothly to the rectifier (not shown).

In the first embodiment described above, the slope of the upstream slope 14 is substantially the same as the slope of the downstream slope 15, but the slope of the upstream slope 14 is larger than the slope of the downstream slope 15. Then, from the upstream slope 14 to the downstream slope 15
It is also possible to further increase the momentum of the ball flow toward.
A concrete example of this is the second embodiment of the present invention shown in FIGS. In the ball receiving tray 20 of the second embodiment, the slope of the upstream side slope 21 is made larger than the slope of the downstream side slope 22 and the upper part of the upstream side slope 21 has the prize ball discharge cover 2 above.
4 and a prize ball downflow opening 25 is formed on the right end surface thereof. In this case, the flow direction of the pachinko balls flowing from the prize ball outlet 27 of the front plate 26 provided at the lower part of the front surface of the pachinko machine onto the upstream slope 21 of the ball tray 20 smoothly changes to the downstream slope 22. As can be seen, the left side of the front surface of the prize ball discharge cover 24 is formed into a smooth curved surface.

In the ball receiving tray 20 of the second embodiment, the slope of the upstream slope 21 is made larger than the slope of the downstream slope 22, so the force of the ball flow from the upstream slope 21 to the downstream slope 22. Can be further increased, and the ball breaking effect due to the force of the ball flow can be further increased. In addition, in the second embodiment, the upper part of the upstream side slope 21 is covered with the prize ball discharge cover 24, and the prize ball outlet 25 is provided on the right end surface thereof.
Since the award ball discharge cover 24 changes the ball flow direction, the ball flow direction of the upstream slope 21 can be smoothly changed to the downstream slope 22. Coupled with the size of the gradient of 21, the momentum of the ball flow from the prize ball downflow opening 25 of the upstream slope 21 to the downstream slope 22 can be effectively increased, and the effect of ball collapse can be further enhanced. it can.

In the second embodiment as well, as in the first embodiment, the slope of the upstream slope 21 is changed to the downstream slope 2.
It goes without saying that the gradient may be substantially the same as the gradient of 2. In addition, the present invention can be implemented with various modifications within a range not departing from the gist, such as two or more stepped portions may be formed on the bottom surfaces of the ball receiving trays 13 and 20.

[0012]

As is apparent from the above description, according to the structure of claim 1 of the present invention, the bottom surface of the ball tray is provided with a step with respect to the upstream slope surface to lower the downstream slope surface. Since it is formed, the flow of balls from the upstream slope to the downstream slope has momentum, and the momentum of the ball flow can break the bridge of pachinko balls on the downstream slope to improve the ball flow. It is possible to prevent jamming.

If the gradient of the upstream slope is made larger than that of the downstream slope, the momentum of the ball flow from the upstream slope to the downstream slope can be further increased. The ball flow can be further improved.
