  • Patent number: 5828920
    Abstract: A shutter is disclosed having a shutter blade frame comprised of two spaced apart rails, each rail incorporating at least one magnet section. Individual pairs of electromagnets are positioned for movement along the rails. At least one shutter blade, having an opening defined thereby, is connected to a pair of electromagnets for movement along the rails from a rest position to an open position. Application of current to the electromagnets causes the at least one shutter blade to travel along the rails causing an alignment of the defined opening with a selected light path to cause an exposure generally of an image sensor such as film. Springs are positioned on the shutter frame for urging the at least one shutter blade to the rest position.
