Abstract:
A relationship between a rim shape and a position of a mounting hole is obtained based on a detection signal from the second position detector (40) by controlling a measuring element shifter (6) to move the leading end of a measuring element for a lens (36) to have contact with an refracting face of the lens (Lm) held in the lens holder.
