Abstract

PURPOSE: To make unnecessary, the visual inspection through automatic discrimination of defective or non-defective small sized gears, by comparing the data in photo electric conversion of the dark and light binary shade image scanning the tooth with light, with the reference data.
CONSTITUTION: The tooth of the tested gear is illuminated with the light source 3 and the image is formed on the line sensor 15 via the mirror 16 and the lens 17. The line sensor 15 has a constitution of several tens to several hundreds of photo electric conversion elements on one row and controls the output with the clock generator 18. This output is converted into binary signal indicating dark and light with the comparator 19 of suitable threshold value, and the data counting the output of the comparator 19 is delivered to the picture data memory circuit 6 with the counter 20. This data output is converted into the shape parameter and discrimination is made by comparing this with the reference parameter inputted from the data input circuit 7 at the discrimination circuit 11.
