Abstract
A cup attaching apparatus for attaching a cup for eyeglass lens processing to a subject lens to be processed, includes: an imaging optical system, which obtains an image of the lens by illuminating the lens with rays of light shaped to be larger in diameter than the lens; a display; a display control unit, which displays, on the display, the obtained lens image and an alignment mark superimposed on the obtained lens image, the alignment mark having substantially the same contour as a small lens portion of a bifocal lens; a first input unit, which inputs an amount of offset of the alignment mark with respect to a cup attachment center; and a second input unit, which inputs layout data for layout of the lens with respect to a target lens shape, wherein the display control unit determines a display position of the alignment mark based on the inputted offset amount and layout data, and displays the alignment mark at the determined display position on the display.
