摘要： A camera mechanism comprises a shutter blade movable to uncover and cover an exposure aperture; a primary spring connected to the shutter blade to normally move the shutter blade to cover the exposure aperture, but susceptible of becoming disconnected from the shutter blade, and a substitute spring connected to the shutter blade to alternatively move the shutter blade to cover the exposure aperture when the primary spring becomes disconnected from the shutter blade.
