Abstract
An improved camera and method of processing for use with an associated film assemblage of the self-developing type, wherein the assemblage is provided with a plurality of self-developing film frames are disclosed. Each frame carries an integral self-developing unit as well as an associated processing fluid pod. Each exposed frame is manually pulled through pressure applying members for rupturing the pod and spreading the fluid before exiting. Simultaneously, the next successive film unit is pulled from a container therefor and indexed by means on the assemblage to the film plane as the pulled unit is automatically separated from the remainder of the assemblage.
Claims12
A method of processing a film assemblage including a plurality of individual self-developing integral film units carried serially in spaced apart relationship on a film strip in a photographic apparatus, said method comprising the steps of:
- applying a withdrawing force on a leading portion of the strip so that an exposed film unit at an exposure station is first advanced through pressure applying means within the photographic apparatus and then emerges from the photographic apparatus;
- and, indexing generally simultaneously therewith the next successive integral film unit to the exposure station from a position remote from the exposure station;
- said indexing step is accomplished by indexing means on the strip cooperating with the pressure applying means;
- the withdrawing force is applied to the strip externally of the photographic apparatus.
A self-developing camera for use with a film assemblage including a plurality of individual film units of the self-developing type carried serially in spaced apart relationship on a strip wherein each film unit includes an image receiving portion, a pod of processing fluid associated therewith, and indexing means, said camera comprising:
- means for storing the film strip;
- means defining an exposure station;
- pressure applying means for rupturing the pod and spreading the processing fluid on an image forming portion of each associated film unit;
- said housing means allowing a leading portion of the strip to be withdrawn from the camera in response to a pulling force so that an exposed film unit at the exposure station is first advanced through the pressure applying means and then emerges from the camera;
- and, the indexing means of the succeeding pulled film unit cooperates with the pressure applying means for positively locating at the exposure station an image portion of the next succeeding film unit leaving the storing means;
- wherein the strip has perforations formed therein at spaced intervals between each of the film units, wherein the perforations are frangible and in response to the indexing means engaging the pressure applying means during application of the withdrawal forces it allows automatic separation of each of the emerging film units from the next succeeding film unit moving to the exposure station.
