Stereo slide mount

A stereo slide mount having identical relative positions between perforations and its individual paired left and right photographic image planes, for mounting a stereo slide film on which an image has been photographed by a stereoscopic camera, comprising:

• a base frame and a cover frame each having two square apertures juxtaposed to each other, said base frame being provided on its film mounting face with positioning pins for coming into engagement with the perforations of the slide film to be fixed, to position two slide films, and said cover frame being provided in its film holding face with pin holes corresponding to said positioning pins, so that said base frame and said cover frame are jointed by fitting said positioning pins in said pin holes,
• wherein a mount system is constructed of a plurality of kinds of stereo slide mounts in which left and right apertures have an equal pitch and an equal width, in which the aperture width is slightly smaller than the image plane width of the film, and in which the pitches of the positioning pins and the pin holes of the left film and the positioning pins and the pin holes of the right film are stepwise different, so that the offsets of the left and right films can be adjusted by the differences of the film mounting pitches of the individual stereo slide mounts.
