PROBLEM TO BE SOLVED: To provide a pinball game machine capable of accurately controlling the position of a moving member with high reproducibility by computing the position of the moving member from the inclination when the moving member is moved on a track whose position is determined by the inclination. SOLUTION: A performance accessory 28 provided in a Pachinko game machine comprises the moving member 39 disposed freely movably on the track T whose position is determined by the inclination, a drive part 63 for moving the moving member 39 along the track T, an acceleration sensor 56 disposed to the moving member 39 for detecting the inclination of the moving member 39, and a position computing means for computing the position of the moving member 39 from the relation of the track T and the inclination detected by the acceleration sensor 56. Thus, the inclination of the moving member 39 is detected by the acceleration sensor 56 disposed to the moving member 39, and the position on the track T of the moving member 39 is computed from the inclination.
