Abstract

PURPOSE:To make it possible to alternate a condenser-diffuser system and diffuser system by constituting the 1st and 2nd optical systems by providing section bodies to a frame equipped internally with a light scattering cylinder and by inserting and extracting selectively them onto and from the optical axis between a light source and negative film. CONSTITUTION:When the 1st optical system 17 which is a condenser-diffuser type system, lid 29 is detached and on the optical axis between light source 30 and negative film 35, light source unit assembly 5 is inserted. In this case, the light of light source 30 is reflected by the 1st diffusion surface 13 via the 1st lighting window 14 to lighten the 1st diffusion filter 15. The 1st diffusion filter 15 is the secondary light source of the 1st optical system 17 and is opposed to negative film 35 via condenser 16. To change the system over to the diffusion lighting, lid 29 of light source bod 3 is detached and light source unit assembly 5 is drawn; and lighting window 21 is changed in direction to the light source optical axis, and the 2nd diffusion filter 22 is faced to negative film 35. In this case, diffusion filter 22 serves as the secondary light source which provides diffusion.
