Abstract

PURPOSE:To enable noncontacting automatic inspection of failure of a plane part, by irradiating a slit light flux to the plane of a rotating circular member with a greater incident angle, receiving the regular reflected light and converting it into an electric signal, and processing it electrically. CONSTITUTION:While rotating a circular member, a slit light flux is irradiated on the plane with a greater incident angle, the regular reflected light is received and it is converted into an electric signal, it is processed electrically and a signal corresponding to failures of the plane is picked up, allowing to make noncontacting detection of failures. For example, to a ring-shaped plane 10a at the upper end of a circular member 10 placed on a rotating stand 12, a slit light flux from a light source 26 having a slit is given to a greater radiation angle theta, the regular reflected light is received at a photoelectric detector 34 and it is converted into an electric signal. If burr or rugged skin of the plane is present, the signal shows a failure, then immediate detection can be made. With this method, quick automatic inspection without contacting can be made.
