PROBLEM TO BE SOLVED: To easily confirm the fatigue of an operator.SOLUTION: Whether or not a fixed time has passed since the previous inspection is confirmed (step S22). When it is confirmed that the fixed time has not passed (step S22: NO), the processing of the step S22 is executed again. When it is confirmed that the fixed time or more has passed (step S22: YES), a flicker value is acquired (step S12), and the flicker value is recorded (step S20). Then, whether or not a fatigue is equal to or less than a predetermined level is determined on the basis of the flicker value (step S14). When the fatigue is equal to or less than the predetermined level (step S14: YES), the processing is returned to the step S22, and when the fatigue is not equal to or less than the predetermined level (step S14: NO), an instruction is output with a voice or character display to make an operator take a break (step S24). |
