Abstract
A device for cutting a sub-finished assembly () of plastic lens () includes a cutting member () and a holding member (). The cutting member has a base (), an upper plate (), an upper cutter () mounted on the upper plate, a lower plate (), a lower cutter () mounted on the lower plate, guiding posts () mounted on the base and guiding the movement of the upper and the lower plates, and a stopper (). The upper plate moves toward the lens before the lower plate and until the upper cutter contacts the cutting point beside the lens. The stopper stops the upper plate from further moving after the upper cutter contacts the cutting point beside the lens. The lower cutter is moved by the lower plate to cut the lens from the sub-finished assembly of the lens. The holding member holds the lens during cutting.
