PROBLEM TO BE SOLVED: To provide a game machine which can prevent illegal operating actions, so called dishonest acts by blocking a clearance otherwise made between the upper and lower doors. SOLUTION: A clearance elimination mechanism (100) has a rotor (110) which turns in linkage with the turning of a key (151) for the actuation of a door lock mechanism (7). The rotor (110) is so formed to be brought into contact with a contact body (120) fixed on a cabinet (1) or the upper door (30) following the rotation of the key (151) in the direction of countering the release of locking and with the further rotation of the key, the lower door (40) is lifted toward the upper door (30) with the contact body (120) as a fulcrum. The clearance elimination mechanism (100) is provided with a reversion preventor (130) for blocking the reversion of the rotor (110) so that the rotor (110) will not get the lower door (40) moved in the direction opposite to that of the upper door (30) when the lower door (40) is lifted toward the upper door (30) and a releasing means (140) which enables the releasing of the operation of the reversion preventor (130).
