Abstract

Abstract A photographic film unit of the self-processing type includes an image-recording portion with attached fluid accommodating or reservoir means for supplying and collecting a processing fluid (e.g. a pod and trap). The fluid supplying means is initially in communication with the leading end of the image-recording portion, but is disposed in front of the image-recording portion (with respect to the direction of viewing the final print) during exposure and is movable relative thereto into substantially coplanar relationship therewith for processing. Thereafter, the fluid supplying means or reservoir is further movable with respect to the image-recording portion for improving the final appearance of the film unit after processing without generating any necessarily disposable waste by placing the supplying means behind the image-recording portion. The movable portion is substantially flat and, in accordance with one feature, is approximately equal in area to the area of the image-recording portion, to evenly cover the entire side of the image-recording portion oppposite from the print-viewing side. The fluid collecting means is located within the borders of the film unit rendering its movement or removal after processing unnecessary. Moreover, the present film unit is arranged to be completely and automatically formed in the camera so that no manipulation by the user is necessary after removal from the camera.
