Device for mounting diapositives in a strip and an apparatus for projecting the strip-mounted diapositives |
摘要 |
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.
