PROBLEM TO BE SOLVED: To provide a slot machine using game balls, capable of driving motors driving variable display devices in a stable state. SOLUTION: This slot machine executes the drive control of reel motors 32L, 32C and 32R rotatingly driving reels 2L, 2C and 2R by a timer interrupt processing (A) executing it at an interval of 0.56 ms, and the driving control of an incorporating motor 101 for driving an incorporating motor 101 by a timer interrupt processing (B) executing it at an interval of 0.4 ms. In executing the game, namely, during the period of executing the driving control of the reel motors 32L, 32C and 32R rotatingly driving the reels 2L, 2C and 2R, this slot machine inhibits generation of the interrupt 0 that causes the timer interrupt processing (B).
