PROBLEM TO BE SOLVED: To recognize fraudulence using a regular key. SOLUTION: The system in a pachinko machine having a front frame openable/closable to an outer frame includes a locking mechanism for locking the front frame, and a key 50 for performing at least the operation to unlock the front door to the locking mechanism. The pachinko machine has an ID signal transmitting device 60 for transmitting a game machine ID signal to specify the pachinko machine. The key 50 has a transmission/receiving part 54 for receiving the game machine ID signal transmitted from the ID signal transmitting device 60, and a storage device 52 for storing the history on the receiving of game machine ID signals. The ID signal transmitting device 60 is disposed near the part of the locking mechanism where the operation of the key 50 for unlocking is performed, and transmits the game machine ID signal when the key 50 approaches the ID signal transmitting device 60.
