<p>PROBLEM TO BE SOLVED: To provide a game machine capable of moving a movable body at a wanted speed regardless of a load of a DC motor by the movable body.SOLUTION: A game machine 100 includes a drive control device (112-n) for controlling a DC motor that drives a movable body (105-n). The drive control device includes: a drive signal generation circuit 16 for outputting a drive signal to the DC motor; and a control circuit 15. The control circuit 15, in a case where an absolute value of a difference between an actual rotational speed when the DC motor is rotated in a first rotational direction by a driving signal corresponding to a predetermined electric power quantity and an actual rotational speed when the DC motor is rotated in a second rotational direction is equal to a predetermined threshold value or larger, generates a rotational speed table representing a relation between a rotational speed and an electric power quantity per a unit time for each rotational direction, and decides an electric power quantity that is supplied to the DC motor which corresponds to a specified rotational speed according to a rotation speed table selected according to the specified rotation direction.</p> |
