Abstract
A photographic film spool, having a central core member (for engagement with a camera film-spool anchoring and rewinding element), contains an integral battery component for electrically powering selected camera functions. The battery, comprised of one or more electrically interconnected cells, is configured for electrical engagement with terminals in the camera particularly through the camera film-spool rewind and anchoring element, with the battery thereby functioning as both the power supply and as part of the film drive. In addition, the battery has sufficient capacity to power the camera functions whereby the film may be totally utilized. The battery further has a shelf life, with such sufficient capacity, for a period of time at least as long as the utilizable shelf life of the film.
