Forming an inlet into which the pachinko balls stored in the hitting ball supply plate flow into the upper part, and forming a supply port to supply the pachinko ball flowing from the inlet to the launch position of the launch rail in the lower part of the front wall, while On the side of the passage frame, a ball cutting member provided with a ball stopper that always protrudes into the ball passage to close the introduction port, and revolves to retreat from the ball passage to open the introduction port,
Always retreat from the ball passage to open the supply port, and by pivoting into the ball passage, the ball supply member provided with a ball support portion for supporting the pachinko ball on its upper surface is arranged vertically, The ball stopper of the ball cutting member and the ball support portion of the ball supply member are alternately moved into and out of the ball passage according to the vertical movement of a lever member that moves up and down in conjunction with a ball striking rod.

[0007]

In the hitting ball supply device described above, when the lever member interlocking with the hitting rod moves upward, the ball stopper of the ball cutting member retreats from the ball passage to open the introduction port, and supports the ball of the ball supplying member. The part rushes into the ball passage and closes the supply port. As a result, the pachinko ball, the inflow of which has been blocked by the ball stopper, flows into the ball passage and is received by the upper surface of the ball support portion. And
When the lever member moves downward in this state, the ball stopper of the ball cutting member projects into the ball passage and closes the inlet, and the ball support portion of the ball supply member retreats from the ball passage and supports it on its upper surface. It acts to send the pachinko ball from the supply port to the firing position of the firing rail.
