However, at the end of a pachinko game parlor, it is necessary to unlock and open the glass frame of each pachinko machine, maintain and adjust the ball rolling plate surface, and clean the inside surface of the glass. However, manually unlocking all the glass frames would be a waste of effort, so it is known to provide each pachinko machine with a solenoid for unlocking. However, when all the solenoids are driven at the same time, there are drawbacks such as the generation of strong sound and the consumption of a large amount of power at once. The applicant proposed a method of unlocking the glass frame in a staggered manner.
