Abstract

PURPOSE: To always and stably fly out a ball by surely cutting a pachinko (Japanese pinball game) ball introduced to a ball entry one by one by a ball sending member and sending it out to a hitting position on a launching rail while rolling from a passage part. CONSTITUTION: When a ball hitting lever is positioned at a operation position, the ball sending member 14 is turned downward due to gravity. Therefore, the pachinko ball B on a ball supply bowl enters the ball entry 16 of a ball supply device 8 from the ball exit 10 of a front plate 6, and it is received with the first ball stopping part 19 of the ball sending member 14. While, when the ball hitting lever is turned to a preliminary ball hitting position, the ball sending member 14 is turned upward by setting the abscissa 22 as a fulcrum. Consequently, the pachinko ball B is moved along the slope of the passage part 18, and it is received with a second ball stopping part 20. When the ball hitting lever is turned to the hitting operation position, the ball sending member 14 is turned due to the gravity and that of the pachinko ball B. Therefore, the pachinko ball B runs on the passage part 18, then, it rolls out from a supply port 17 to the hitting position on the hitting rail 3.
