SURFACE INSPECTING APPARATUS

摘要

PURPOSE:To accurately inspect the defect position of an object to be inspected, by storing detection data in the predetermined position of a memory part determined by a value based on the distance from a detector to measure the same in an operation processing part. CONSTITUTION:When a shearing system is operated and a coil E begins to advance, the inspection of the coil E is performed by various detectors D1-Dn. The detection data from the various detectors D1-Dn are inputted to a central processing apparatus A every when the coil E advances over a unit length (u) by the pulse signal from a pulse generator PG. The inputted detection data is stored in a slot through input circuits H1-Hn corresponding to the various detectors D1-Dn by the deviation of a pointer being the value obtained by dividing the distance from an input reference point S to the various detectors D1-Dn by the unit length (u) and read in a data editing part 12 on the basis of the indication of said slot. The data editing part 12 calculates the total number of defects K in the coil E which have passed on the basis of the read detection data.
