Abstract:
1. A lens manufacturing apparatus comprising: a concave-convex shape forming unit that makes a notch in a surface of a workpiece to form a concave-convex shape portion in the surface of the workpiece, the concave-convex shape portion including a concave portion that is deeply cut from the surface of the workpiece, and a convex portion that protrudes from the surface of the workpiece; a resin supply unit that supplies resin for the lens onto the surface of the workpiece; a resin curing unit that cures the supplied resin for the lens, the resin curing unit being movable independently from the concave-convex shape forming unit and the resin supply unit; a moving unit that moves the concave-convex shape forming unit and the resin supply unit relative to the workpiece; a working head that has the concave-convex shape forming unit and the resin supply unit, wherein the moving unit moves the concave-convex shape forming unit and the resin supply unit by moving the working head; and a control unit that controls driving of the concave-convex shape forming unit, the resin supply unit, the resin curing unit, and the moving unit so as to form the concave-convex shape portion extending in a predetermined direction, supplies the resin for the lens between adjacent concave-convex shape portions and cures the supplied resin for the lens.
