Abstract
A camera uses a film cartridge having a light-shielding door for opening/closing a film inlet and outlet opening. A cartridge chamber accommodates the film cartridge. A cartridge chamber lid is provided at the opening of the cartridge chamber. A first driving mechanism drives the cartridge chamber lid. A second driving mechanism drives the light-shielding door. A control section controls the second driving mechanism to maintain the light-shielding door in an opened state when it is not possible to take out the film cartridge from the cartridge chamber.
