Motor stop control device for gaming machine and gaming machine provided with the motor stop control device

Abstract

The present invention can accurately stop a reel at a target position and, at the same time, can offer a wide variety of reel stop process. A motor stop control device includes a stepping motor 70 having two pair of excitation phases as a drive source of a reel which is stopped in response to a manipulation command from the outside and displays a plurality of symbols. The motor stop control device further includes a speed reduction transmission mechanism 700 which transmits the rotation of the stepping motor 70 to a rotary shaft which rotates the reel 3 at a predetermined speed reduction ratio, and a main CPU 40 which, when a command for stopping the stepping motor 70 is generated in response to the command from the outside, selects either one of reel stop control processing 1 which executes a stop control based on all-phase excitation with respect to the stepping motor 70 and reel stop control processing 2 which executes a control to reduce a rotational speed of the stepping motor 70 and, thereafter, executes the stop control based on two-phase excitation with respect to the stepping motor 70.
