MICROFILM RECORDING AND DEVELOPING APPARATUS ABSTRACT OF THE DISCLOSURE The present invention describes a microfilm recording and developing apparatus, providing an improved method and device for advancing and processing exposed film. The microfilm recording apparatus comprises a film storage means, a camera means, film advancing means, optical means, processing means, drive means and heating means. The film advancing means transports a predetermined length of film from the film storage means to the camera means for exposure. The optical means associated with the camera means optically imprints and photographically records an image on the exposed segment of film. The processing means, responsive to actuation of the optical means, mechanically transports and chemically treats the exposed film. The processing means includes a plurality of containers for developing, fixing, neutralizing and washing the exposed film. The processing means further includes container film guide means and coupled sets of film engaging pinch rollers adjacent an entrance and exit of each one of the containers. The pinch rollers are arranged so as to effect the conveyance of the exposed film in loop and self-threading fashion via the container film guide means through and from each one of the containers. The drive means is coupled to the pinch rollers for film processing movement of the exposed film to a collection point. The heating means dries the chemically treated film.
