Abstract

PURPOSE: To prevent discharging by forming the lens end part of the photoreceptor side of the lens block larger than the diameter of the through-hole of the second lens substrate and covering the edge portion of the through-hole.
CONSTITUTION: The device is so arranged that the respective portions of the original D are imaged on projection face (photoreceptor) P by the 1st lens block 81 and 2nd lens block 82 and the entire image of the original D is formed through movement of the projection face P. The surface part 181 on the photoreceptor side of the element lens 182 of the 2nd lens block is made larger in diameter than the through-hole of the lens substrate and insulators 183, 183' of the state covering the end parts are disposed in proximity or close contact opposedly to the end face 181. Since this constitution prevents discharging, this copying apparatus is made to the apparatus by which discharging with the other member is prevented.
