Abstract
PURPOSE: To improve condensing efficiency at low cost by specifying the material and shape of a light transmitting means.
CONSTITUTION: The light transmitting means 12 to be disposed between original photographic paper 11 and photo detector 13 is formed by coiling and overlapping one end face 12b of one sheet of photoconductive sheet material having approximately even thickness and width to circular shape or the like in conformity with the shape of the photo detecting surface 13a of the photo detector 13. The one end face 12b is closely contacted to the photo detecting surface 13a and the other end face 12a of linear form is put in the position as close to the original photographic paper 11 as possible. With this arrangement, at the time when the reflected light of the laser light radiated onto the original photographic paper 1 through a light polarizer 14 enters the photo detector 13 by way of the light transmitting means 12, it is efficiently condensed and is entered to the photo detector with good efficiency.
