Abstract: A slide mounter where a photographic film transparency is advanced to an operation station and is cut from a photographic film web and punch holes are punched. The cut and punched film transparency is then inserted into a slide mount at an insertion station. The punch holes are designed to cooperate with pin registrations in the slide mount to lock the film transparency in place within the slide mount. The photographic film transparency is cut from a photographic web which is supported along a support axis. The film transparency is pushed from the operation station after it is cut and punched along a push axis into the slide mount M. The orientation of the push axis and the support axis is design to accommodate exposed film where the image is 90.degree. from the normal orientation of images recorded by a photographic camera.
