PURPOSE:To make the reduction in size of a camera possible and eliminae the need for checking the state of an electric power source battery by constituting a thin type battery in one body to the body of a container for photographic films and using the same as the electric power source battery. CONSTITUTION:In the sectional view of a photographic film 3, a film container body 10, a film 11 contained by being wound in a roll shape, positive and negative electrodes 12, 13, and light shielding members 14, 15 are shown. A thin type battery is constituted in the body 10. Namely, a manganese dry cell is constituted of a sheath 20 of plastics or the like, a positive pole current collector 21, a positive pole 22 such as manganese dioxide, an electrolyte holding layer 23, a negative pole such as zinc 24, a carbon film 25, a negative pole current collector 26, and a sealing material 27. With this constitution, the replacement of the film 3 results in simultaneous replacement of the battery as well. In other words, there is no need for worrying about the consumption of the battery used. |
