摘要：
An arithmetic control circuit (52) is configured to bring the measuring element (38) for a lens into contact with at least two points (measurement points P1, P2) of one of two refracting surfaces of the lens Lm held in the lens holder by controlling the measuring element shifter (driving motor 6), obtain the coordinates of the two points according to the detection signal from the position detector (linear scales 24, 40), and obtain a curve value Cv of one refracting surface of the lens from the difference of the coordinates of the two points.
