PROBLEM TO BE SOLVED: To prevent a game customer from being disadvantaged.SOLUTION: When receiving a command to release a locking mechanism of a CR unit 10 and a mount frame, which is included in requirements for unlocking a tray unit, the CR unit 10 determines whether or not a state of a sensor unit 30 satisfies a prescribed release permission condition and, when determining that the state satisfies the release permission condition, permits to release the locking mechanism of the CR unit 10 and the mount frame, thus preventing dropping of Pachinko balls to be counted when removing the tray unit. |
