とを特徴とする円形部材の外径測定装置。 An outer diameter measuring table on which a circular member for measuring the outer diameter is placed, and a pair of light reflection types placed opposite to each other on both sides of the circular member placed on this outer diameter measuring table in the diametrical direction. Each of these light reflection type sensors includes a light emitting element that irradiates the outer peripheral surface of the circular member with laser light, and a light receiving element that receives the laser light reflected from the outer peripheral surface. The laser displacement meter is capable of measuring the distance to the outer peripheral surface based on the displacement of laser light, and is characterized in that the outer diameter of the circular member is calculated based on the output of these laser displacement meters. A device for measuring the outer diameter of a circular member.
