A disc camera for use with a disc film cartridge includes upper and lower camera walls spaced from one another by a distance less than the height of the cartridge housed in a cartridge chamber. The upper wall is formed with an opening which allows a part of the cartridge housed in the cartridge chamber to project therefrom. A frame is formed in the cartridge chamber so as to be fitted with an exposure aperture of the cartridge when a rear cover of the camera is closed. The frame serves to prevent exposure of a film in the cartridge to unwanted light. A covering member which protects the projecting part of the cartridge against impact which might be applied thereto also prevents entry of dust into the cartridge chamber. The opening may be formed on a lower camera wall or on both of the upper and lower camera walls.
