<p>PROBLEM TO BE SOLVED: To provide a game machine improving a protection property against fraudulent unlocking and capable of reducing an occurrence of deformation and damage of a component.SOLUTION: A ball using type reel game machine 1 comprises a front door 3 openably/closably supported with respect to an outer frame 2. The front door 3 includes, on a back side thereof, a locking device for locking the front door 3 with respect to the outer frame. The locking device includes a cylinder lock operated by a key, and a piece member that is displaced in conjugation with the operation of the cylinder lock, and is locked to a receiver metal fitting of the outer frame 2. When no key is inserted into the cylinder lock, it becomes impossible to displace the piece member. Further, the locking device further includes a protection member that, when the front door 3 is in an open state, projects outward of a peripheral edge of the front door 3 and, when the front door 3 is closed, inhibits an occurrence of such a trouble that the piece member and the receiver metal fitting are collided with each other to cause deformation or damage of the piece member.</p> |
