Abstract
Apparatus and a method for handling and reading any one of a number of film strips, each having a number of segments with each segment containing a plurality of information-containing, high-reduction image frames. The film strips are housed in a cassette which is movable with respect to a fixed reference to align a desired film strip with a reading station disposed across the optical path of an optical system. A film strip is moved out of the cassette by a force applied to one of its side edges. Control information carried by each film strip is sensed as the film strip moves out of the cassette and the sensed information is used to control the distance through which the film strip moves so that a particular segment thereof will stop at the reading station. The optical system is moved relative to the reading system so that the optical path of the optical system is selectively alignable with a particular image frame of the film strip removed from the cassette.
