However, in the conventional surplus ball tray, since the inner peripheral surface of the ball hole is formed as a vertical surface, the game ball discharged from the ball hole into the ball box is not formed. Are concentrated and discharged at a position directly below the ball hole, and are stacked in a pyramid shape at that position.
If such a state is left as it is, the amount of the game balls stacked increases, and eventually the game balls fall down from the side of the ball box and are scattered around. Therefore, the player must level the ball appropriately while paying attention to the amount of the game ball discharged from the surplus ball saucer, which is extremely troublesome, and some of the players have a hand when touching the game ball. Many people do not want to touch the game balls as much as possible because they get dirty. Further, there are many cases where it is necessary to discharge the game balls from the surplus ball tray to the ball box, while the game is being played, but the player does not need to worry about the amount of the game balls discharged to the ball box, There is also a problem that if it is necessary to concentrate on the game, the player cannot concentrate on the game.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to allow game balls discharged from a surplus ball tray to be substantially concentrated without being concentrated at one place in a ball box. An object of the present invention is to provide a surplus ball tray for a pachinko game machine that is evenly distributed and accommodated.

[0005]

In order to achieve the above-mentioned object, the present invention provides a shutter plate for opening a ball hole in a storage portion for storing game balls and opening and closing the hole. In a surplus ball tray for a pachinko machine, which is provided so as to be capable of reciprocating movement and discharges game balls downward by moving the shutter plate in an opening direction, at least a part of an inner peripheral surface of the ball hole is inclined inward. (A slope toward the center of the hole). As a result, the game balls discharged from the surplus ball tray are dispersed substantially uniformly without being concentrated at one place in the ball box.

[0006] Preferably, the inner peripheral surface facing the inclined surface of the inner peripheral surface is reversely inclined. As a result, the game balls discharged from the surplus ball tray are dispersed more widely in the ball box.
