Abstract
PURPOSE:To obtain highly reliable measurement results, by a method wherein a waveform to be detected is binarized as compared with 2 reference voltages being different from each other, prohibiting the output of measured result when a difference between the two exceeds a given value. CONSTITUTION:A signal 2a of a member 1, which is detected by a camera 2, is inputted to binary circuits 5 and 7 to be compared with a reference voltage. The output from the binary circuit 5 is inputted to a computing circuit 8, and a high- level period thereof is computed. The outputs from the binary circuis 5 and 7 are inputted to a detector 9 where a noncoincidence part between the two is detected, and the results are inputted to a circuit 10. The circuit 10 is provided with a counter and a comparator, computes an input, compares the computed value with a set value, and outputs a prohibition signal. The prohibition signal is inputted to a computing circuit 8, and the output of the computing results is suspended.
