PROBLEM TO BE SOLVED: To provide a game machine capable of preventing an opening operation to the other door member while one door member is in an opened state.SOLUTION: The game machine includes a game machine body part 3 (one door member), a game main block 5 (the other door member) behind thereof, and a lock device 120 for locking the game machine body part 3 and the game main block 5. The lock device 120 unlocks the game machine body part 3 by a clockwise turning operation of a key, unlocks the game main block 5 by a counterclockwise turning operation of the key, and is provided with a fixing mechanism 128 to fix the key so that if the key is given a clockwise turning operation and reaches a prescribed turning position, the key becomes impossible to be turned in a counterclockwise direction at the turning position. Therefore, if by chance a wrongdoer tries to give a counterclockwise turning operation to the key, the turning operation cannot be given, and a fraudulent unlocking of the game main block 5 can be prevented. Accordingly, a problem of a fraudulent conduct being performed by opening the game main block 5 which is unlocked by a wrongdoer while unnoticed by people related to a game hall can be prevented.SELECTED DRAWING: Figure 4 |
