PROBLEM TO BE SOLVED: To provide a game machine capable of increasing a rotational torque at the time of acceleration. SOLUTION: This game machine is constituted to enable a smooth acceleration processing to be carried out even in a short period of time by an accelerating operation while using a magnetic exciting phase of high torque as an initial excitation phase. With this arrangement, it is possible to cause a player to concentrate on a rotating pattern barrel without eliminating a fun of the game. COPYRIGHT: (C)2004,JPO
