Abstract

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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 94 words
In information retrieval apparatus: a cassette having an open end, a pair of opposed sides, and means on the inner surfaces of the sides for mounting a number of strips in stacked relationship therewith with each strip being movable relative to the sides at least partially out of the cassette through said open end, said cassette having a recess in one side thereof through which a portion of one side edge of each strip is thus engageable by edge drive means, whereby each strip can be moved relative to said cassette in opposed directions.
Claim 2
Dependent Claim 94 words
In information retrieval apparatus: a cassette having an open end, a pair of opposed sides, and means on the inner surfaces of the sides for mounting a number of strips in stacked relationship therewith with each strip being movable relative to the sides at least partially out of the cassette through said open end, said cassette having a recess in one side thereof through which a portion of one side edge of each strip is thus engageable by edge drive means, whereby each strip can be moved relative to said cassette in opposed directions.
Claim 3
Dependent Claim 45 words
In apparatus as set forth in claim 1, wherein the inner surface of each side is provided with a number of parallel grooves, there being a groove on one side for each groove, respectively, on the other side, each groove terminating at said open end.
Claim 4
Dependent Claim 59 words
In apparatus as set forth in claim 1, wherein the other side of the cassette has an end margin adjacent to said open end, said one side having an end margin spaced from said open end, there being an open space between said open end and said end margin of said one side, said open space defining said recess.
Claim 5
Dependent Claim 19 words
In apparatus as set forth in claim 1, wherein said one side has an opening therein defining said recess.
