Abstract
A microfiche viewer structured for examining new microfiche film. The film is typically still in roll form as it comes from the microfiche camera. Plural magnifications of the microfiche image are selectively available; one, to reproduce a whole fiche upon the viewing screen for general observation of photographic quality, the other, to reproduce perhaps four frames of a whole microfiche for detailed observation of quality. The apparatus is structured for convenience in viewing. The different magnifications are obtained by selectively interposing objective lenses of different focal length in the light path adjacent to the microfiche film on the side opposite to that occupied by a light source. Motor driven film transport means are provided atop the apparatus proper.
