Abstract: A shutter mechanism comprising an aperture through which ambient light is passed to cause a film exposure, a pair of shutter blades supported for pivotal opening movement in opposite opening directions away from one another to uncover the aperture to permit ambient light to pass through the aperture and for pivotal closing movement in return closing directions towards one another to re-cover the aperture and supported to allow them to be pivoted simultaneously in the same direction to cause accidental shutter opening when a physical shock is applied to the shutter blades in the opening direction of one of the shutter blades, is characterized in that each one of the shutter blades completely covers the aperture in order that both of the shutter blades must be removed from the aperture to uncover the aperture to permit ambient light to pass through the aperture, and a single fixed stop is positioned between the shutter blades to prevent either one of the shutter blades from pivoting in the same direction as the

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.
