PROBLEM TO BE SOLVED: To easily grasp the error concerning display control out of a game machine and to improve the efficiency of inspection or test by outputting an error signal showing an error state when it is judged by an error stage judging means that a proper display control is not performed. SOLUTION: A CPU 101 provided on a display control board 80 starts an initial screen command receipt waiting timer after a power source is inputted, and judges whether the display control command outputted from a main board 31 is an initial screen command or not. When this judgment is NO, an abnormal screen display processing is performed to output a pattern display device error signal that is a test signal. When the initial screen command receipt waiting timer is timed out before the display control command is received, the processing is also transferred to the abnormal screen display processing. An inspecting device is connected to test signal terminals 111, 112 so that fluctuating period of pattern, display pattern, and decision of pattern can be recognized, and the inspection work is performed. |
