PROBLEM TO BE SOLVED: To provide a substrate case which can discover a dishonest act easily and a game machine providing the same. SOLUTION: A substrate case 50 which stores a main control substrate 60 is composed of a case main body 51 and a case cover 52. The case main body 51 and the case cover 52 are fixed so as not to be separated as long as one of the cases are broken. A RFID device 70 which keeps security data is embeded in the case cover 52. Security data which is kept in the RFID device 70 can be read from the RFID device 70 by transmitting access data from a RFID detector 80 which can transmit and receive data between the RFID device 70 by radio. Thereby, whether the substrate case which is provided on the slot machine is the proper substrate case 50, or not can be detected easily. |
