ABSTRACT:
A camera comprising an aperture through which ambient light is passed to cause a film exposure, a shutter blade pivotable open to uncover the aperture to permit ambient light to pass through the aperture and pivotable 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 actuator movable to pivot the shutter blade open to uncover the aperture, is characterized in that a blocking device is positioned within a blocking range of the shutter blade to block the shutter blade from being pivoted open to uncover the aperture when the shutter blade is moved accidentally due to mechanical shock, and the shutter blade is supported to be moved out of the blocking range of the blocking device when the shutter actuator is moved to pivot the shutter blade open to uncover the aperture.
