COLOR TONE INSPECTION DEVICE AND COLOR TONE INSPECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a color tone inspection device and a color tone inspection method which suppress deterioration in inspection accuracy, even if the thickness of an inspection object varies.;SOLUTION: A color tone inspection device 1 includes: a light emission unit 2 for emitting light to an inspection region 90 on a surface of an inspection object; and a light reception unit 3 for receiving reflection light reflected in the inspection region 90, and inspects a color tone of the surface of the inspection object on the basis of the reflection light received by the light reception unit 3. The light emission unit 2 is configurated in such a manner that the variation of illuminance in the inspection region 90 falls within a predetermined range when the thickness of the inspection object is within tolerance.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
