ABSTRACT:
A film image projecting apparatus such as a microfilm reader and a microfilm printer adapted to automatically retrieve desired information by searching blip marks provided laterally of frames in a roll film. Conventionally, a roll film containing a plurality of rows of frames has been retrieved in most cases by manually placing a target frame in an exposure section. The known apparatus also has the disadvantage of blip marks becoming displaced from an illuminated area when an image is projected in magnification onto a screen, thereby impairing the retrieval operation. The present invention provides a film image projecting apparatus having means for eliminating this disadvantage. More particularly, the disclosed apparatus comprises a film transport mechanism, a cross slide mechanism, a projecting optical system, and a control device for suitably controlling these elements to enable desired information retrieval. The film image projecting apparatus according to the present invention is particularly suited for retrieving and copying images photographed into a plurality of rows of frames in a roll film.
