Apparatus and method for driving roulette game machine

An apparatus for driving a roulette game machine played in such a way that a scoreboard which is partitioned into a plurality of sections at predetermined intervals is rotated, and a score is determined depending on a position at which a stopper is placed on the scoreboard when the scoreboard stops, the drive apparatus comprising:

• a support shall;
• a coil unit coupled to the support shaft;
• a stator rotatably coupled to the support shaft at a position facing the coil unit;
• a rotor rotatably coupled to the support shaft at a position facing the stator;
• an outer wheel having a planar shape with a hollow space;
• and
• an inner wheel disposed in the hollow space of the outer wheel, the inner wheel having the scoreboard,
• wherein the stator is coupled to either the outer wheel or the inner wheel and the rotor is coupled to a remaining one of the outer wheel and the inner wheel, and the stator and the rotor are attached to or separated from each other depending on turning power applied to the coil unit on/off.

A method of driving a roulette game machine, comprising an inner wheel, an outer wheel, and a coil unit configured such that an inner wheel and an outer wheel are attached to each other by electromagnetic force generated from the coil unit and are rotated, the roulette game machine being played in such a way that a scoreboard which is disposed inside the outer wheel and partitioned into a plurality of sections at predetermined intervals is rotated, and a score is determined depending on a position at which a stopper of the inner wheel is placed on the scoreboard when the scoreboard stops, the method comprising:

• (a) applying power to the coil unit to attach the inner wheel to the outer wheel so that the inner wheel is rotated along with the outer wheel;
• (b) determining using a control unit whether on from among a speed at which the inner wheel rotates, the number of rotations of the inner wheel, and a duration during which the inner wheel rotates exceeds a corresponding preset standard;
• (C) interrupting power applied to the coil unit using the control unit to separate the inner wheel from the outer wheel when, at (b) determining, one from among the speed, the number of rotations, and the rotation duration of the inner wheel exceeds a corresponding preset standard;
• (d) determining whether the inner wheel is in a stop state;
• and
• (e) displaying a score, corresponding to a position of the stopper on the scoreboard, on a display unit when, at (d) determining, it is determined that the inner wheel is in the stop state.

• (d) determining whether the inner wheel is in a stop state;
• and
• (e) displaying a score, corresponding to a position of the stopper on the scoreboard, on a display unit when, at (d) determining, it is determined that the inner wheel is in the stop state.
