Abstract
A film and battery unit comprises a filmstrip having a photosensitive side with successive imaging areas at which respective exposures are to be made and a non-photosensitive side, and a thin, flat, flexible battery extending at least substantially along the non-photosensitive side of the filmstrip for providing electrical energy incidental to making the exposures, whereby the filmstrip and the flexible battery can be coiled into a roll inside a film cassette for example. Preferably, an adhesive releasably secures the flexible battery to the non-photosensitive side of the filmstrip to allow the flexible battery to be stripped from the filmstrip before the filmstrip is chemically processed to render the exposures visible.
