PROBLEM TO BE SOLVED: To improve productivity by increasing efficiency of the supply of unmachined workpieces and the collection of machined workpieces without complicating a configuration. SOLUTION: A centering device 102 has a fixture 104 composing a bell clamp 106 and a function for sucking and holding a lens 101 or a machined lens 101a by exhaust from a vacuum source 110 at each bell fixture 105. An unmachined lens 101 held by the chuck 155 of a loading arm 153 is sucked and held by the fixture 104 in a separated state. Since the machined lens 101a is collected by being transferred to the chuck 155 from a state in which it is sucked and held on the separated bell fixture 105 side, the supply of the unmachined lens 101 to the bell clamp 106 and the collection of the machined lens 101a to a pickup mechanism 117 are enabled at the same time by the one reciprocating operation of the loading arm 153 between the bell clamp 106 and the pickup mechanism 117.
