Abstract
PURPOSE: To eliminate measurement error factors of the surface state of a measured object by operating the width signal from one end of the visual field of a detector to the scanning width start end of a measured object and the width signal from one end of the visual field of the detector to the scanning terminal end of the measured object to obtain actual width dimensions.
CONSTITUTION: By input of scanning start pulse S12 from a start pulse generation circuit, linear array sensor 3 starts scanning, and simultaneously, first and second width signal detection circuits 22 and 23 output rise signals such as S22 and S23. When scanning from the scanning start end to the scanning terminal end of measured object 1 is performed, signal S17 is outputted from comparator circuit 71. First width signal detection circuit 22 indicates rise due to input of signal S17 to obtain width signal WS, and second width signal detection circuit 23 indicates rise due to a signal caused by the scanning terminal end of measured object 1 in scanning to obtain width signal WE. Consequently, operation (WE-WS) is performed by detection circuit 24 to obtain accurately actual width dimension Wx.
