In a camera, a movable lens barrel is movable between a collapsed position and photographing positions determined in front of the collapsed position. A slidable cover is movable, covers a front of the movable lens barrel when in a closed position, and uncovers the front of the movable lens barrel when in an open position. A cover stopper is movable, and retains the slidable cover in the open position when in a stopping position, and allows the slidable cover to move to the closed position when in a releasing position. A locking projection shifts in response to shifting of the movable lens barrel, retains the cover stopper in the stopping position when the movable lens barrel is in a photographing position, and allows the cover stopper to move from the stopping position to the releasing position when the movable lens barrel is in the collapsed position.
