Abstract
A belt-driven shutter mechanism includes a shutter frame (20, 22) with an aperture (21), a plurality of hubs (30) rotatably positioned around the aperture, a corresponding plurality of shutter blades (14), one blade being supported by each hub, and a belt (32-42) attached to each of the hubs so that rotation of one hub rotates one of the shutter blades and applies tension to the belt to rotate a remainder of the plurality of hubs and shutter blades. The belt may include a corresponding plurality of spring sections (38) to relieve tension in the belt. The belt may include thin sections (34, 42) to ease wrapping onto the hubs and thickened sections (36-40) to improve moldability. The hubs may include attachment features (44-52) to ease wrapping of the belt onto the hubs. Registration features (54, 56) may be included to maintain registration between the hubs and the frame. One of the hubs may include a feature (58) to mate with an associated shutter actuation magnet.
