摘要:
A photographic roll-film pack, comprised of a light-proof core case with roll-film, with a photographic shutter, film advance means with manual control, a picture counter, a shutter-release device and apertures and/or lenses of a picture-taking lens and/or viewfinder defining optical beam paths, with a covering for the core case which leaves uncovered at least one manual control, is designed so that the covering is formed by a protective case (11, 12), enclosing the core case (1, 2), which is composed of shells (11, 12) of essentially rigid plastics which is at least transparent in the areas of apertures and/or lenses of a picture-taking lens and/or viewfinder defining optical beam paths. The roll-film pack is thereby protected against moisture, dirt and damage, but can still be manufactured cost-effectively using automated production and it can be re-assembled following removal of an exposed film.
