Claims

[Scope of utility model registration request]

When scanning light is applied to the object to be copied and the projected image is passed through a lens for enlarging or reducing the image and then applied to a photoreceptor, which is a charged semiconductor, the black parts of the object to be copied remain charged. A developer, which is a powder with an opposite charge, is attached to this area, and this is transferred to paper, fixed, and converted to an arbitrary magnification in both the vertical and horizontal directions by an optical copying device that makes copies. An optical copying device characterized by having functions.
