However, in the conventional Pachinko island, the belt conveyor is a horizontal conveyance belt.
As described above, when the horizontal conveyance belt is used, the pachinko balls supplied on the belt are likely to roll in the belt conveyance direction, and in particular, the number of overflow balls falling from the conveyance end portion increases.
This necessitates an increase in the number of pachinko balls supplied to the horizontal conveyor belt, which requires an increase in the total number of pachinko balls, and increases the burden on the pachinko ball polishing and transport devices. The problem of end up occurs.

  Also, if the pachinko balls are easy to roll in the belt conveyance direction, gaps will occur between the pachinko balls on the belt, the density of the pachinko balls will become coarse, the number of conveyance balls will decrease and the supply of balls to each pachinko machine will be insufficient There is also the problem of falling.

Moreover, in the conventional Pachinko island, there is a configuration in which a gradient adjusting mechanism for adjusting the gradient angle is provided on the horizontal conveyance belt.
As described in paragraph (0011) of Patent Document 1, this gradient adjusting mechanism speeds up the replenishment of balls by providing a gradient, and smooth even when a large number of balls are required. This is a configuration for enabling replenishment of nadama.
Thus, in order to speed up the replenishment of the balls, it is necessary to provide the belt conveyor with a downward slope from the conveyance start end portion toward the conveyance end portion. In this case, compared with the case where the belt conveyor is provided horizontally. As described above, the pachinko balls are easy to roll in the belt conveyance direction, and the number of overflow balls falling from the conveyance end portion further increases.

The present invention has been made in order to solve the above-described problems. In the configuration of the upper supply device in which the pachinko ball is conveyed by the belt conveyor, the overflow ball that drops from the conveying terminal end of the belt conveyor. By reducing the number, the problem of increasing the total number of pachinko balls is eliminated, and the burden on the polishing device and the conveying device of the pachinko balls can be reduced.
In addition, by restricting the pachinko balls from rolling in the belt conveyance direction, the gap between the pachinko balls on the belt is reduced to increase the conveyance density, and the increase in the number of conveyance balls ensures the supply of balls to each pachinko machine. The challenge is to provide pachinko islands that can be used in the future.

In order to solve the above problems, the pachinko island of the present invention (Claim 1)
