Patent abstract

A shutter operating system is provided that depends on electromagnetic energy to operate shutter blades. A permanent magnet and solenoid system operate the shutter blades. Movement of the magnet causes the shutter blades to move between an open and a closed position over a lens. The permanent magnet can be moved between a pair of spaced coils by selectively energizing first one coil then the other. The magnet can be attached directly to a shutter blade or in the case of a rotary shutter, the magnet can be attached to a drive ring that in turn is mechanically coupled to the shutter blades.
