<P>PROBLEM TO BE SOLVED: To provide a shooting ball supply device preventing that a plurality of game balls pass a ball supply path or that a sprocket comes into a non-rotatable state by preventing that the sprocket rotates to a direction opposite to a direction allowing passage of a game ball. <P>SOLUTION: The shooting ball supply device A shooting a game ball B by forward/backward movement of a spring part 23 includes: the sprocket 25 formed with a plurality of ball carriage recessed parts 28 on the periphery, and rotating by the weight of the game ball B to make the game ball B pass; and a stopper 30 alternately moving an upper engagement part 32 and a lower engagement part 33 forward/backward to the sprocket 25 by reciprocatingly rotating to engage them with projection curve parts 28a of the ball carriage recessed parts 28. The shooting ball supply device A also includes: an association mechanism 40 reciprocatingly rotating the stopper 30 in association with the forward/backward movement of the spring part 23; and a reverse rotation prevention mechanism 35 preventing that the sprocket 25 rotates to the other direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
