ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to cameras and, more particularly, to energy sources for use in cameras.
2. Background Description
Automatic film winding mechanisms in cameras and the like used, for example, in modern photographic equipment are normally battery powered. Batteries for these mechanisms are small, lightweight and expensive. Furthermore, disposing of spent such batteries creates pollution, especially from electrolytes contained therein which may leach into neighboring water sources.
Accordingly there is a need for easily recyclable batteries for film transport mechanisms.
SUMMARY OF THE INVENTION
It is a purpose of the invention to provide easily recyclable batteries for film transport mechanisms.
The present invention is a removable data storage unit, preferably a film storage cylinder, for an image capturing device, preferably a camera. An energy storage source is contained within the film storage cylinder. Preferably the battery is a rechargeable battery. The film storage cylinder includes a pair of electrical contacts, each of the pair being located at opposite ends of the cylinder and connected to a corresponding one of a pair of electrical contacts internally mounted within the film storage cylinder. Preferably, the film storage cylinder is plastic.
