Lens suction jig installing apparatus and method of determining lens position using apparatus thereof

A lens suction jig installing apparatus for installing a lens suction jig, comprising:

• a position adjustable pedestal for holding a spectacle lens where a plurality of indices are formed that are provided with a predetermined space on a surface;
• a position adjusting device for displacing the pedestal within a position adjustable range;
• an image capture device for capturing an image of the spectacle lens held by the pedestal;
• an image processing device for image-processing to detect the indices based on the image of the spectacle lens image-captured by the image capture device;
• a display device for displaying an image;
• a display control device for controlling in order to make the display device display an image of the spectacle lens image-captured by the image capture device and an image of the indices obtained by the image-processing;
• and
• a jig installing device for installing a lens sucking lens at a predetermined position of the spectacle lens,
• wherein the display control device specifies a position in a vertical direction with a predetermined interval from a straight line connecting one of the indices obtained by the image-processing, obtains the interval from the straight line connecting one of the indices, approximates the obtained interval to a predetermined value, and specifies a suction position of the lens suction jig.
