  • Patent number: 4410088
    Abstract: A holder (10) for photographic slides which is normally in a rectilinear condition in which it can be contained in a box. The holder includes a flexible element (12) which has connecting portions (18, 20) at each end thereof. A tongue (28) associated with the portion (18) co-operates with a tongue associated with the portion (20) and the portion (18) co-operates with a flange (34) to secure the holder into the form of a closed loop. A unit (14) is attached to the element (12) and to the portions (18, 20) and forms a series of pockets (54) each of which serves to receive a photographic slide. From the holder (10) the slides are transferred directly to the pockets of a slide magazine for projection. The holder (10), when straight, occupies less space that a rotary projector magazine and is far less expensive to produce.
