Claims

[Claims for Utility Model Registration] 1. First and second lens holders that are arranged opposite to each other on the same axis with a lens to be processed in between, and that press the lens from both sides during lens processing; and the first lens holder. a rotating means for rotating the second lens holder; a supporting means for rotatably supporting the second lens holder; a separating means for moving the first and second lens holders toward and away from each other in order to clamp and release the lens; is held between the first and second lens holders,
A lens processing device comprising: a tool for processing the outer periphery of the lens being rotated by the rotating means, the suction pad being attached to the second lens holder and abutting against the concave surface of the lens; and the suction pad being attached to the lens. a vacuum suction means for holding the lens on the suction pad by bringing it into contact with the concave surface of the suction pad and drawing a vacuum; The suction pad is brought into contact with the concave surface, and the lens is suctioned and held by the suction pad by the vacuum suction means, and then the lens is unclamped, and the first and second lens holders are brought closer to each other by the separation means. A lens processing device characterized in that the lens processing device is configured to hold a lens between the lenses. 2. The lens processing apparatus according to claim 1, wherein the outer diameter of the suction pad is 2/3 or less of the outer diameter of the lens.
