PURPOSE:To enable a beautiful copy to be formed on a metallic plate, such as a printing plate or printed circuit by projecting the image of the original to be copied placed on an original platen through a semitransparent material on a photosensitive body. CONSTITUTION:The semitransparent sheet 6 is brought into close contact with the original platen 1 and unfolded on it, and the original 5 to be copied is placed on it. Light emitted from a light source 2 is diffused with the sheet 6 and the light reflected from the full reflective metal face of the original 5 is directed in the direction toward a lens 3 to form an image on a photosensitive drum 4, thus permitting a beautiful image good in contrast to be obtained. |
