A film cartridge support in a photographic camera is provided in a film chamber which holds a film cartridge. The support includes a stopper for limiting the rotation of the film cartridge around a shaft of the film cartridge, and the stopper is supported for rotation in a direction approximately parallel to a surface of a film set on the camera. A modification of the support can include a block portion on the support extending across the lower end of the film chamber to prevent incorrect insertion of the film cartridge into the film chamber. A cut portion which is large enough to allow insertion of an operator's finger may be provided at the top end of the film chamber to allow easier insertion and removal of the film cartridge into and from the film chamber.
