PROBLEM TO BE SOLVED: To enhance the speed of door opening work by simultaneously unlocking the upper/lower doors by a single unlocking device when opening a front door in a game machine having the front door partitioned into upper/lower ones and individually locked. SOLUTION: This game machine is so formed that locking parts 60 and 80 are detached from locked parts 27 and 17 and changed into unlocked state by downward moving moving bodies 51 and 71; an unlocking projection 72 provided at the lower-door moving body 71 is positioned above an abutment part 52A of the upper-door moving body 51 in the locked state, a key body inserted into a key hole 44 of the lower door 40 is rotated in the unlocking direction, the lower-door moving body 71 is downward moved, the unlocking projection 72 abuts on the abutment part 52A, and when the key body is further rotated in the unlocking direction till a prescribed unlocking angle, the upper-door moving body 51 and the lower-door moving body 71 are downward moved with the unlocking projection 72 abut on the abutment part 52A to unlock the upper door 30 and the lower door 40.
