Abstract
In the gaming machine, when the motor drive instruction to drive the motor occurs based on an instruction from an external, a constant voltage is applied to the motor and the motor is driven through the motor drive circuit. And when the excitation current value flowing in the motor becomes the first current value based on the constant voltage applied to the motor through the motor drive circuit, the voltage with on-time and off time is repeatedly applied to the motor through the motor drive circuit. Further, when the rotation speed of the motor becomes constant based on the voltage with on-time and off-time applied through the motor drive circuit, the constant voltage is applied to the motor based on the motor stop instruction through the motor drive circuit, thereby the motor is stopped.
