PROBLEM TO BE SOLVED: To previously prevent a plurality of game balls from existing in a shooting position of a shooting device in a pinball game machine.SOLUTION: A shooting ball detection sensor 52 is disposed at a back side of a shooting position of a shooting rail 21 to detect a game ball set to a shooting position of the shooting rail 21. The shooting ball detection sensor 53 is disposed outside the shooting rail 21, and detects a game ball shot by a shooting device 20 and passing above the shooting rail 21. A control device determines that a game ball shot by the shooting device 20 does not become a foul ball and is shot to a game area 11, and controls a supply device 40 to supply the game ball to a shooting position at an earlier point of time between the time when predetermined time passes after the output of the shooting ball detection sensor 52 is changed from on to off and the time when the output of the shooting ball detection sensor 53 is changed from off to on.SELECTED DRAWING: Figure 1 |
