A mode dial mechanism for a photographing device comprising a photographing lens, according to the present invention, includes a lens mover, a mode dial, and a mode judge. The lens mover moves the photographing lens. The mode dial is for selecting a mode from a plurality of modes, including a lens housing mode where the photographing lens is housed in a housed position which is inside the photographing device. The mode judge determines whether the lens housing mode should be set or not, when the lens housing mode is selected. When the mode judge determines that the lens housing mode should be set, the lens housing mode is set, and the lens mover moves the photographing lens to the housed position.
