Abstract: A photocopying apparatus is disclosed of the type including optical means for progressively scanning an object in a strip-like manner and for projecting the image of the scanned strip portion of the object on a light-responsive medium that travels in synchronism with the scanning means. The invention is characterized by the provision of exposure means including a bundle of light conducting rods for illuminating the scanned strip portion of the object. The light output ends of the rods are arranged in a narrow zone that extends adjacent the object normal to the direction of scanning by the optical scanning means.
