Motor control device and game machine

A game machine comprising:

• a game machine body;
• a movable body that is movably arranged in a front surface of the game machine body;
• a motor that drives the movable body;
• a motor control device that controls the motor;
• and
• a performance controller that controls performance according to a game state,
• wherein the performance controller generates a control command and transmits the control command to the motor control device,
• wherein the control command comprises a motor type identification signal indicating a type of the motor and a rotation signal designating a target rotation amount of the motor corresponding to a moving distance from a present position of the movable body to a moving destination and a target rotation speed of the motor according to the game state, and
• wherein the motor control device comprises:
• a communication unit that receives the control command;
• a sensor interface that receives a detection signal from a rotation angle sensor when the motor is a DC motor, the rotation angle sensor outputting the detection signal every time the motor rotates by a first rotation angle;
• a DC motor drive signal generator configured to generate and output a first drive signal rotating the DC motor at the target rotation speed when the motor is the DC motor;
• a stepping motor drive signal generator configured to generate and output a second drive signal rotating a stepping motor at the target rotation speed when the motor is the stepping motor;
• and
• a controller,
• wherein the controller refers to the motor type identification signal to determine whether the motor is the stepping motor or the DC motor,
• wherein the controller calculates a total rotation amount from rotation starting of the motor by the number of receiving times of the detection signal when the motor is the DC motor,
• wherein the controller causes the DC motor drive signal generator to output the first drive signal so as to let the motor stand still when the total rotation amount reaches the target rotation amount, and
• wherein the controller causes the stepping motor drive signal generator to output the second drive signal so as to rotate the motor by the number of stepping motor steps corresponding to the target rotation amount when the motor is the stepping motor.
