The amount of change Δd per prescribed time t0 of the distance d obtained by the distance measuring mechanisms 2 is calculated by each distance measuring mechanism 2. If even one of the plurality of calculated amounts of change Δd exceeds a prescribed range Δd0, it is discriminated as a safe state. If all of the plurality of calculated amounts of change Δd are within the prescribed range Δd0, it is discriminated as an abnormal state, with a warning issued.SELECTED DRAWING: Figure 2
