[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pachinko machine, and more particularly to an upper plate for supplying a pachinko ball toward a ball striking device.
[0002]
[Prior art]
The upper plate of the pachinko machine receives the prize balls released from the prize ball device, accumulates the hit balls to be replenished as the game starts, and sends them one by one to the hit ball launcher so that they can be continuously fired. It is. For this reason, the upper plate has a ball receiving plate for storing the balls, and an alignment passage for aligning the balls stored in the ball receiving plate in a line using a gradient and sending them one by one. The ball is guided.
