Abstract

PURPOSE:To position an original easily through displaying the position relation between the original and a copied picture clearly, by indicating an area on an original placing plate to be copied by providing the original placing plate with a part where light is diffused. CONSTITUTION:On original placing plate glass 15, two out of four corners of an area to be copied are written in the longitudinal coordinates 16 of the original placing plate, but other two corners are shown by forming the surface of the original placing plate 2 as a mat and by forming a light diffusion part. When an original placing plate cover is open, indexes written by providing the mat can be seen by a user, so that the original us positioned easily, no parallax appears.
