PROBLEM TO BE SOLVED: To realize a game machine in which a broken power supply protection circuit can be repaired at a low cost, in a short time and with ease. SOLUTION: A resistor R1 forming a power supply protection circuit and a part such as a surge absorber Z1 are mounted on a relay board 74. The terminal of every part is bent into a nearly L-shape and inserted into a socket 78 communicating with a circuit pattern 74b formed on the reverse of the relay board 74. The terminal of every part is fixed by a clamp 47 from the above of the socket 78. This structure requires only the simple work of removing the clamp 47 fixing the part, extracting the part from the socket 78, inserting a new part into the socket 78 and fixing it by the clamp 47 to complete a repair, when a part is broken due to overvoltage.
