ABSTRACT:
A novel film cartridge, camera for use with such cartridge and method of making such cartridge are disclosed. The cartridge is in form of a pocket of a material which is impermeable to light and which accommodates a multi-exposure film strip having a length at least equal to the length of the pocket. The pocket is provided with at least one opening extending transversely to its elongation and through which a leading end of the film strip extends to the exterior of the pocket so that it can be engaged by a film transporting mechanism of a camera suitable for accommodating such a pocket, which mechanism transports the film strip either in one continuous movement out of the pocket and into a storage space of the camera from where it is sequentially transported into the pocket in increments during which exposures are made, or else the film is sequentially transported out of the pocket and into the camera storage space with exposures being made during each transporting step and the exposed film is thereupon returned in a single movement into the pocket. However, the pocket may also have two parts one of which accommodates the non-exposed film strip which is then transported during exposures into the other part so that the film strip becomes completely located in the other part when it is fully exposed and a re-transportation into the first part of the pocket is not necessary. Cameras suitable for use with various embodiments of the novel cartridge are also disclosed, as well as methods of making the cartridge.
