ABSTRACT:
The gaming machine according to the present invention has the reels3L,3C,3R on each of which a plurality of symbols are formed, the stepping motors59L,59C,59R for rotating and stopping the reels, the stop buttons11L,11C,11r for stopping rotation of the reels3L,3C,3R and the microcomputer40and the motor drive circuit49for controlling rotation and stop of the stepping motors. And both the microcomputer40and the motor drive circuit49divides the step angle per one step in the stepping motors into a plurality of small step angles, thereby both the microcomputer40and the motor drive circuit49conducts the step control for the stepping motors based on the divided step angles.
