IPC: H04N1/028
Filed: 1991-04-19
Abstract: PURPOSE:To eliminate the influence of giving secondary reflection to transmitted light by irregularly reflecting light on one face facing to the reflecting face of a mirror. CONSTITUTION:An original 5 is put on a glass 6 and illuminated with light emitted from a light source 2 so that reflecting light is sent to a lens 3 through three mirrors 1-a, 1-b, 1-c to form an image on a light/electricity converting element 4. In this case, provided with the reflecting face to transmit specified wavelength light and one face facing to the reflecting face formed as a sand- ground face given sandblasting treatment. e.g. is the third-step mirror 1-c. As a result, the mirror 1-c separates light X sent from the mirror 1-b into unspecified wavelength light Y and specified wavelength light Z. Then, the light Z is irregularly reflected after hitting a face provided with a means of irregularly reflecting light from one face facing thereto, without reaching the light/ electricity converting element.
