Abstract
PURPOSE: To simplify an adjustment of the position of an element by providing a linear mark, crossing the subscan direction of an optical system at right angles, outside of the effective original read region of contact glass.
CONSTITUTION: When light source 12 of optical scan system 16 is positioned under linear mark 18, light source 12 is made to come on an the image of linear mark 18 is image-formed on fixed scan element 15 by way of mirror 13 and image-forming lens 14. Then, inferior position precision to subscan direction of element 15 and improper position precision between elements are detected in the form of a position shift from linear mark 18 of element 15 and variation in output signal.
