Abstract

See full text

An appearance inspection apparatus radiates light from a light source to a flat inspection surface of an object to be inspected as diffused light with an illumination device, and photographs the inspection surface with a camera. The camera and the light source are arranged in a positional relationship that satisfies θ≠α at any positions on the inspection surface, where θ represents an angle formed between a straight line connecting an arbitrary position on the inspection surface to the camera and a line perpendicular to the inspection surface at that position, and α represents an incident angle of the diffused light.
