ABSTRACT:
Apparatus for storing, transporting, exposing and developing photosensitive film is disclosed in which a camera supports a table along which a carriage is slidable. The carriage serves to store and feed out lengths of film into a camera exposure station. A source of vacuum acting between a sheet of flexible plastic material and a translucent platen for the camera at the exposure station causes the film to be flattened against the platen for film exposure. Thereafter, the vacuum is broken by movement of the carriage and the exposed film is urged into the nip of rollers which carry the film through a developing station supported by the table.
