A film cartridge includes a first container for accommodating unexposed roll film and a second container for taking up exposed roll film, the first and second containers being separably connected with each other. A stationary holding member for holding the second container is mounted on the inner surface of the back lid of a photographic camera. A movable holding member for holding the first container is mounted on the inner surface of the back lid and moved from a first position near the stationary holding member to a second position apart therefrom when the back lid is closed. The film cartridge is held by the movable and stationary holdings members with the first container held by the movable holding member and the second container held by the stationary holding member. The first and second containers can be automatically separated and respectively inserted into the film cavity and the film take-up cavity by closing the back lid.
