Abstract
A photographic apparatus for providing an instant film system for transmission electron microscopes includes a film carrier and film unit handling apparatus compatable with existing TEM equipment. Film carrier plates, each standardized to accept an instant film sheet and to subsequently enable automatic separation of the latter, are varied in exterior configuration to conform to each type of TEM unit, and a single processor is provided for handling film processing with carrier plates utilized in any of the TEM units. The carrier plates are standardized to enable automated separation of individual exposed film sheets from the respective carrier plates in the processor, and a transfer base or transfer box is provided to cooperate with the receiver box of a given TEM design and with the processor which includes a reciprocating slide feed mechanism by which each individual film unit is ejected from the box. The processor then separates the film sheet from the carrier plate, assembles it with processing materials and advances it to the nip of a processing roller pair.
