Abstract

PURPOSE: To easily perform positioning of a light transmissive base plate to be exposed and a mask, by placing focuses on reflection marks on the base plate and the mask through the contrast between the dark and pale patterns projected upon the plate and mask.
CONSTITUTION: A light transmissive plate 17 which is positioned on the optical axis of a projecting optical system and provided with dark and pale patterns on both surfaces is provided and the dark and pale patterns respectively projected on a base plate 12 to be exposed and mask 13 are received by means of an image sensor 20. Focalizing operations of the base plate and mask are carried out by moving the base plate, mask and an observing optical system relatively to each other so that average contrast values of the dark and pale patterns projected on the surface or back of the base plate 12 and a reflection mark 11 can become equal to each other. Therefore, even if the transmissive base plate having a lower reflectivity is on one side, focalizing operations can be carried out easily and accurate positioning can be made.
