In an apparatus for processing a lens in accordance with data of the shape of a lens frame, it is detected at a great accuracy that the processing has been completed. <??>An apparatus for processing a lens comprises a lens unit 4 which comprises a holding shaft supporting the lens in a manner such that the lens 1 can be freely rotated and can freely displace the lens 1 towards a tool 50, a positioning member 34 which can be brought into contact with and separated from the lens unit 4 and restricts the displacement of the lens unit 4 towards the tool at a position corresponding to the processing amount of the lens 1 which is obtained based on data of the shape of a lens frame, a sensor arm 300 which amplifies the relative displacement between the lens unit 4 and the positioning member 34, and a sensor 320 which detects that the lens unit 4 has been brought into contact with the positioning member 34 based on the amplified relative displacement. <IMAGE>In an apparatus for processing a lens in accordance with data of the shape of a lens frame, it is detected at a great accuracy that the processing has been completed. <??>An apparatus for processing a lens comprises a lens unit 4 which comprises a holding shaft supporting the lens in a manner such that the lens 1 can be freely rotated and can freely displace the lens 1 towards a tool 50, a positioning member 34 which can be brought into contact with and separated from the lens unit 4 and restricts the displacement of the lens unit 4 towards the tool at a position corresponding to the processing amount of the lens 1 which is obtained based on data of the shape of a lens frame, a sensor arm 300 which amplifies the relative displacement between the lens unit 4 and the positioning member 34, and a sensor 320 which detects that the lens unit 4 has been brought into contact with the positioning member 34 based on the amplified relative displacement. <IMAGE> |
