Abstract

PURPOSE:To make the machine compact and reduce its cost by disposing a slender member which shields the luminous flux entering a projecting lens from the boundary part of an original and an original abutting member on the under side of orignial placing glass. CONSTITUTION:A slender member 10 of the width enough to shield the luminous flux entering a projecting lens from the boundary part of an original 1 and an original abutting member 3 is disposed on the under surface of original placing glass 2, and the surface on the under side thereof directing to the projecting lens is formed as a diffusive white surface. Since the boundary part of the original 1 and the abutting member 3 is covered by the white slender member 10, the appearance of a shadow by the boundary part on a copy is obviated, and a nonimage part is formed at the leading end of the copy in this way, thus the boundary of the image part and the nonimage part is sharper and the machine is made compact and lower in cost.
