Abstract
A motor-driven shutter mechanism is provided with a lens protecting mechanism to protect the lens of a camera. The lens protecting mechanism consists of one or more lens guard members movable back and forth upon operation of the camera's motor-driven focussing and aperture setting mechanism to cover and uncover the lens. The lens guards are operably interconnected with the same motor which controls the focussing and aperture setting operations of the camera.
