Abstract
PURPOSE:To simplify the positioning and the focusing of an original by providing a movable mirror to be inserted to an optical path between an image forming lens and an exposure position, and a mask having a mark representing a print size and a mark for focusing at a position conjugate with the exposure position via the movable mirror. CONSTITUTION:At the time of performing the focusing of the image forming lens 8 and the positioning of the original, the movable mirror 45 is inserted to the optical path after placing a reflecting original 2 on an original platen 1, and a light source (halogen lamps 3a and 3b) is lit. An optical image projected by the light sources 3a and 3b and transmitting the mask is reflected on the movable mirror 45, and projected adversely on the reflecting original 2 via the image forming lens 8. The focusing of the image forming lens 8 or the positioning of the original is performed as observing an adversely projected optical image. After that, the light sources 3a and 3b light out, and also, after the movable mirror 45 is retreated, the copy of the reflecting original 2 is performed. In such a way, it is possible to perform the alignment and the focusing simply and easily.
