A substrate coverincludes a conductive portionhaving a shape corresponding to a peripheral edge region of a substrate. Since at least part of the conductive portion includes transmissive portionseach formed of a light transmissive member, it is configured so as to allow desired light to penetrate through. The position of each edge portion of the substrate is detected in such a manner that the substrate is disposed with the substrate coverplaced thereon between light irradiation means and a light detecting unit, irradiation light directed from the light irradiation means located above the substrate to the edge portion of the substrate is made to penetrate through at least part of the substrate cover, the edge portion of the substrate is then irradiated with light from the irradiation means.
