Abstract

PURPOSE:To obtain both the reflecting an shielding functions of the photographing light, by forming the shutter blade by laminating a colored plastic film on a black metallic sheet that received a light shielding process. CONSTITUTION:A shutter plate 10 consists of a slit forming blade 13 plus auxiliary blades 14-17, and the rear blade group is folded into the lower side of an aperture 10a. Each of the blades 13-17 is formed by laminating a colored plastic film (b) on a black metallic sheet (a) which received a light shielding process. The reflection factor of the film (b) is set equivalent to that of a photographing film, and at the same time the surface of the film (b) is set opposite to a photographing lens. In such a way, a shutter blade, which has no exfoliation although it is rubbed to another blade and the light reflecting and shielding functions, can be obtained.
