とを特徴とする複写装置の光学系。A light beam from an original placed on a contact glass is imaged on a photoreceptor through an optical system having an imaging lens and at least one mirror provided on the image side optical path to perform slit exposure. In the optical device of the copying machine, the distance from the intersection of the 6 mirrors closest to the photoconductor of the exposure optical system and the optical axes of the 4 bundles of exposure points in the vicinity of the exposure position of the photoconductor is the exposure position of the photoconductor. A member having a test pattern on its surface and a light source for irradiating the test pattern on the member are provided at a position equal to the distance up to the distance from a position that is pivotally supported so as to be swingable around an axis in a parallel direction and reflects the light beam from the imaging lens toward an exposure position on the photoreceptor;
A rotating means is provided between a position where the light is reflected toward the test pattern, and an image of the test pattern illuminated by the illumination light source is formed on the contact glass, and this is observed to determine the magnification and/or An optical system for a copying machine, characterized by adjusting focus.
