  • Patent number: 9421720
    Abstract: An apparatus including a cup attaching unit, includes: a lens support portion for supporting a lens on a reference axis extending in a vertical direction; a support arm to which an attaching portion to which the cup is attached is attached; a moving arm for support the support arm to be movable so that the attaching portion can be directed in a downward direction toward the lens support portion and in an upward direction or a forward direction; and a lever configured to be operated by the operation and rotate the support arm so as to direct the attaching portion in from the second direction to the first direction. The lever is provided at the support arm and lowers the attaching portion together with the moving arm after the attaching portion is directed in the downward direction.
