Abstract
An illuminating system for an image processing measuring apparatus according to the present invention is composed on an inclined-incident illuminating device B mounted removably to a body tube and projecting obliquely a luminous flux to an object to be measured, a ring-shaped incident illuminating device mounted removably to the body tube and projecting a ring-shaped luminous flux to the object other than a vertical-incident illuminating device projecting the luminous flux emitted from an optical source from the direction just above the object, and a switching for switching the luminous flux emitted from the light source to either of the inclined-incident illuminating device and the ring-shaped incident illuminating device. As a result, there is proved the illuminating system for an image processing measuring apparatus by which an illumination suitable for a shape or a contour of an object to be measured can be selected from the group consisting of vertical-incident illumination, inclined-incident illumination, and ring-shaped illumination. The illuminating system for an image processing measuring apparatus is excellent in ease of operation, and is constructed economically in a com…
