Abstract

PURPOSE: To speed up the judgment of approval or rejection, by inspecting the form of the screw being inspected in non-contact method by using linear beam.
CONSTITUTION: When a linear beam is projected from a device 3 in the screw pitch direction, the brightness corresponding to the screw profile and the adjacent part of a screw being inspected 2 is converted into an electric signal in an image pickup means 5. And, of this electric signal, the signal position corresponding to the screw profile is determined, at every horizontal scanning, from the interval from the horizontal synchronism generating position or properly set measuring standard position to be supplied into a computer 8. I this computer 8, the supplied signal is compared with the pre-stored standard screw pattern, and the difference signal of the two and the preset allowable range value are compared to judge the approval or rejection.
