Abstract
A camera in use of a film cartridge which contains a film wound around a winding shaft in a light-shielding condition, wherein an output of a motor that is disposed in a movable cartridge chamber drives the cartridge chamber to open and close, driven members that are arranged in a camera body, and driven members that are arranged in the cartridge chamber. Therefore, there is no need to arrange a complicated transmitting mechanism which transmits a driving force from a motor in the camera body, which makes it possible to simplify a driving force transmitting mechanism.
