The gaming machine according to the present invention has the reels 3L, 3C, 3R on each of which a plurality of symbols are formed, the stepping motors 59L, 59C, 59R for rotating and stopping the reels, the stop buttons 11L, 11C, 11r for stopping rotation of the reels 3L, 3C, 3R and the microcomputer 40 and the motor drive circuit 49 for controlling rotation and stop of the stepping motors. And both the microcomputer 40 and the motor drive circuit 49 divides the step angle per one step in the stepping motors into a plurality of small step angles, thereby both the microcomputer 40 and the motor drive circuit 49 conducts the step control for the stepping motors based on the divided step angles.
