PROBLEM TO BE SOLVED: To facilitate connection and reduce the cost in connecting a plurality of control devices to each other, installed separately according to each application. SOLUTION: A main board 34 and a sub-board 35 are connected to each other by a single transmission means 49. A main CPU 40 and a sub-CPU 44 can perform two-way information communication through the single communication means 49. When the power is applied to a pachinko machine, the sub-CPU 44 inputs a key code to the main CPU40. In the main CPU 40, it is discriminated whether or not the input key cord is correct. Thus, it can be confirmed whether or not the main board 34 and the sub-board 35 are properly connected to each other. Further, since the pachinko machine can dispense with a buffer, the cost can be lowered. COPYRIGHT: (C)2004,JPO
