PROBLEM TO BE SOLVED: To provide a game machine capable of easily identifying malfunction when a detection unit composing one portion of a performance input means malfunctions.SOLUTION: Check processing of a motion sensor performed by a performance control unit following power on starts a timer after all of sensors emit light and frame lamps light up (S3701 to 3703). When a detection signal is received from one of the sensors (Yes for S3704), the sensor that has outputted the detection signal is identified, light emission of the sensor is stopped, and the corresponding frame lamp is turned off (S3705 to 3707). When a timer value is larger than a threshold T after the corresponding frame lamp is turned off (Yes for S3708), it is determined whether a sensor that is emitting light exists (S3709). When the sensor that is emitting light exists (Yes for S3709), an error is reported (S3710). |
