Abstract
A lens edger which is capable of measuring the curvature of an eyeglass lens is disclosed. The lens edger includes a carriage which rotatably fixes a pair of lens fixing shafts and moves the position of the lens fixing shafts clamping a lens to be processed; a lens rotation motor for rotating the lens fixing shafts; a carriage driving means for moving the carriage; and an apparatus for measuring a curvature of the lens. The apparatus for measuring lens curvature includes a curvature tracer which contacts with a side of the lens and detects a curvature of the lens by moving horizontally according to the curvature of the lens during a rotation of the lens; a curvature tracer rotator which rotates the curvature tracer to a position for measuring the lens curvature, and to which one end of the curvature tracer is inserted in a manner of allowing sliding movement of the curvature tracer in a horizontal direction; and a slider base which guides the movement of the curvature tracer in the horizontal direction, and provides a restoring force to the curvature tracer so that the lens and the curvature tracer can be maintained in a contacted state.
