摘要：
A camera comprising an aperture through which ambient light is passed to cause a film exposure, a shutter blade movable open to uncover the aperture and movable closed to re-cover the aperture and susceptible of being moved accidentally due to mechanical shock such as when the camera is dropped or jarred, and a shutter release button manually depressible for the shutter blade to be moved open to uncover the aperture, is characterized in that a blocking device is positioned adjacent or adjoining the shutter blade to prevent the shutter blade from being moved open to uncover the aperture due to mechanical shock, and is movable away from the shutter blade to permit the shutter blade to be moved open to uncover the aperture, and the shutter release button is connected with a driver that moves the blocking device away from the shutter blade to permit the shutter blade to be moved open to uncover the aperture only when the shutter release button is manually depressed.
