Device for mounting diapositives in a strip and an apparatus for projecting the strip-mounted diapositives
First Claim
1. A film strip device for mounting a plurality of slide film sections in side-by-side relationship in a row to introduce successively the diapositives for projection in a slide projector and the like, comprising at least one first flexible sheet member having at least two picture openings therein in side-by-side relationship in a row, at least one second flexible sheet member similarly having at least two picture openings therein in side-by-side relationship in a row, said first and second sheet members being fastened to each other in face-to-face relationship with their respective picture openings being aligned and one of said sheet members overlapping the other sheet member by one picture opening such that a portion of one of said sheet members corresponding in length to one picture opening is not covered whereby a plurality of said first and second sheet members can be fastened to each other in alternating overlapping relationship to form a film strip of such a length to accommodate a predetermined number of slide films sections, a frame having a second picture opening therein interposed between said sheet members and having its second picture opening corresponding with aligned picture openings in said two sheet members, said frame picture opening being slightly larger than a diapositive to be positioned therein and larger than the sheet member picture openings, said frame having a thickness greater than that of the diapositive such that a diapositive is freely moveable within a said frame and has play between said sheet members, said sheet member picture openings being smaller in size than the individual slide film sections mounted in the film strip.

Abstract
Diapositives are mounted in a strip formed by a pair of flexible sheet members each having at least two picture openings therein in side-by-side relationship and the sheet members are fastened to each other in face-to-face relationship mutually offset by a single picture opening. The frame is interposed between the sheet members and a diapositive is moveably positioned within an opening in the frame. The thickness of the frame is greater than that of the diapositive so that a diapositive is freely moveable within a frame opening and has play between the sheet members. An apparatus for projecting the strip mounted diapositives is provided with a pair of cassettes one of which contains a strip in which the diapositives are mounted and the second cassette contains a strip without any diapositives. The ends of the strips are automatically connected to each other for successively introducing the diapositives into the apparatus.
