Claims

[Scope of utility model registration request]

In the scattered light flaw detection device described above, the scattered light type flaw detection device is equipped with a light projector that irradiates light toward the cracked part of the glass bottle, and a light receiver that introduces scattered light from the cracked part of the glass bottle and obtains a detection signal according to the intensity of the flaw. A first polarizer is provided on the optical path from the projector to the glass bottle to linearly polarize the irradiated light, and the first polarizer is provided on the optical path from the glass bottle to the light receiver to linearly polarize the light on the optical path. A glass bottle flaw detection device comprising: a second polarizer that linearly polarizes light in orthogonal directions.
