PROBLEM TO BE SOLVED: To provide a game machine capable of finding a defect in a sub-liquid crystal display device 3450 without any trouble.SOLUTION: In transmission of LOCKN signal output request data, a peripheral control MPU 4150a performs circuit connection such that a forcible switching circuit 3420c can receive the LOCKN signal output request data by a sub-liquid crystal receiver IC, and the sub-liquid crystal receiver IC of a sub-liquid crystal drive board 3425 outputs a LOCKN signal as a response signal. The peripheral control MPU 4150a determines that no defects are generated in the sub-liquid crystal display device 3450 when the LOCKN signal is input. Contrarily, when the LOCKN signal is not input, the peripheral control MPU 4150a determines that a defect is generated in the sub-liquid crystal display device 3450 and executes communication error display processing as notification processing. |
