Document Type and Number:

WIPO Patent Application WO/2005/098521

Kind Code:

Abstract:

An automatic suction device for an eyeglass lens and a method for determining suction jig installation position, capable of recognizing that a frame exchange lens holder is being installed on a placement table, making transition to installation work of a frame exchange mode, and avoiding an erroneous contact between the frame exchange frame and a lens holding frame. The kind of holding means placed on the placement table is determined from an image of the inside of an opening (141), which image is taken by a CCD camera (105), and the installation position of a suction jig (121) at an eyeglass lens (L) placed on a frame exchange lens holder (300) is obtained.
