<p>PROBLEM TO BE SOLVED: To suppress overheat when a solenoid is actuated for a long period time by a simple configuration in a game machine including the solenoid for operating a movable object.SOLUTION: The game machine comprises: a solenoid for displacing a movable object; control means for outputting a control signal of the solenoid; and drive control means for outputting a drive signal of the solenoid. The drive control means includes an oscillation circuit, and a counter circuit for outputting a first rectangular wave signal and a second rectangular wave signal having a period longer than that of the first rectangular wave signal. A first period when on period is set to a first prescribed period, and a second period when the on period is set to a second prescribed period shorter than the first prescribed period and the on period and off period are alternately set are alternately provided. During the first period, while the second rectangular signal is kept off, an output pattern of the control signal or a reverse pattern of the output pattern is defined as a drive signal. During the second period, while the second rectangular signal is kept on, the output pattern of the first rectangular wave signal or the reverse pattern of the output pattern is defined as the drive signal.</p> |
