Abstract
A light is illuminated, for example, from the side of a flange of a syringe. An imaging processing is carried out with an image signal issued by imaging a reflected light from the edge of flange by means of a TV camera or CCD camera located, for example, in an upward slant direction. Detecting an irregular state of the image signal caused by the reflected light, a crack or chip at the flange are recognized. The irregular state of the image signal, which is obtained by detecting parts where the light is not reflected, brings the method of being easy to detect the crack or chip at the flange.
