To eliminate double balls from happenings and to prevent the discharge and stop times from synchronizing with a win timing by adjusting them by controlling a pachinko machine based on a basic period comprising a ball feed operation signal of a ball feed solenoid and a ball shooting operation signal of a ball discharge solenoid.

A ball shooting solenoid 9 shoots balls in such a state that a rotor 9a receives the rotation force by a voltage fed from an output device, for example, at 0.6 second intervals and a pachinko hammer 9b attached to the rotor 9a is swung by the rotation of the rotor 9a. A ball feed solenoid 31 is driven by a pulse on signal outputted from an output device, for example, at approximately 0.6 second intervals, magnetically attracts and lifts a free movement end of an operation piece 16 whose one end is lifted by a spring 16a and free movement end of the other end is lowered, and allows a ball receiver stopper 5 to feed the balls.
