VARIABLE APERTURE MECHANISM FOR CREATING DIFFERENT APERTURE SIZES IN CAMERAS AND OTHER IMAGING DEVICES

摘要

An apparatus includes a first blade configured to be coupled to a first magnet and a second blade configured to be coupled to a second magnet. At least one of the blades has at least one cutout. The apparatus also includes electromagnetic motors configured to generate different electromagnetic fields to (i) cause the magnets to move the blades into a first configuration and (ii) cause the magnets to move the blades into a second configuration. The blades are separated to form a larger aperture in the first configuration, and the at least one cutout in the blades forms a smaller aperture in the second configuration. The apparatus may further include a cover plate and a base plate. The base plate can include an opening that defines the larger aperture and blade stops and stop pins configured to stop movement of the blades.
