PROBLEM TO BE SOLVED: To suppress a fraudulent action due to a fraudulent operation and to prevent a failure due to the deterioration of operability, in a game machine where a setting operation is validated on the basis of a prescribed validating operation. SOLUTION: A ball using type drum game machine 1 includes an outer frame 2 and a front door 3 supported so as to be opened and closed to the outer frame 2. On the front door 3, a back mechanism unit 5 or the like is supported so as to be opened and closed. The separation opening of the front door 3 and the outer frame 2 and the separation opening of the back mechanism unit 5 and the front door 3 are regulated by a locking device 900. On the rear surface side of the back mechanism unit 5, a setting key switch is disposed and fixed. In a state where the separation opening is regulated, the movement of the base part of a door body 441 is regulated in a state where the covering part 443 of the door body 441 covers the insertion part of the setting key switch. Meanwhile, in a state where locking is released and the back mechanism unit 5 is opened for a prescribed amount to the front door 3, the movement of the base part of the door body 441 is allowed and the cover of the setting key switch by the covering part 443 is released.
