Zusammenfassung:An optical measuring device measures optical characteristics of an object in a non-contact state. The optical measuring device has a light source that illuminates an object surface, a light receiver that receives a light beam reflected from the object surface, and a light-regulating member that regulates an illuminating light beam radiated onto the object surface and the reflective light beam reflected from the object surface. The light-regulating member has a first light-regulating member that determines at least one of an illuminating region and a reflective region with respect to the object surface, and a second light-regulating member that determines a region where the reflected light beam that is reflected from the object surface and is incident on the light receiver is measured on the object surface.
