ABSTRACT:
The invention is a motor stop control device for a rotating reel type gaming machine1which includes a stepping motor70having two pairs of excitation phases as a driving source of reels3having a plurality of symbols drawn thereon and in which the stepping motor is stopped in accordance with an operational instruction from outside. The device includes a deceleration transmission mechanism700for transmitting the rotation of the stepping motor70to rotating shafts for rotating the reels3at a predetermined reduction ratio and a main CPU40for performing control for reducing the rotating speed of the stepping motor70when a stop command for the stepping motor70is generated according to an operational instruction from the outside and for performing stop control of the stepping motor70through two-phase excitation.
