PROBLEM TO BE SOLVED: To optimize initial excitation of a stepping motor in starting reverse rotation, in a reel type game machine in which the reel can be reversely rotated.SOLUTION: Before start of rotation of a reel, if the excitation state of the reel in a stopped state is one phase excitation, the excitation state is renewed by "-1" in accordance with a prescribed excitation changing order, with normal compensation processing performed that compensates to two phase excitation immediately before. Further, if the rotation of the reel this time is reverse rotation, re-compensation processing is performed in which the excitation state compensated by the normal compensation processing is re-compensated to an excitation state that is suitable for reverse rotation. |
