<p>PROBLEM TO BE SOLVED: To provide a game machine, such as a pachinko, which prevents fraudulent unlocking of a locking device.SOLUTION: A pachinko machine 10 comprises: an outer frame; a body frame 12 provided at the front of the outer frame and supported by one side of the outer frame such that the body frame 12 can be opened/closed; and a front door frame 13 provided at the front of the body frame 12 and supported by one side of the body frame 12 such that the front door frame 13 can be opened/closed. A locking device locks the body frame 12 to the outer frame, and also locks the front door frame 13 to the body frame 12. The body frame 12 is unlocked by inserting a key into a cylinder lock 91 and rotating the key in one direction whereas the front door frame 13 is unlocked by rotating the key in the other direction. If fraudulent unlocking is tried in this state by using a wire inserted between the outer frame and body frame 12, the fraudulent unlocking is blocked by an internal locking member disposed behind the boundary between the outer frame and the body frame 12.</p> |
