GLASS LENS PATTERN SHAPE MEASUREMENT DEVICE

摘要

A measurement probe moving device (6) controls a top edge of a glass lens pattern measurement probe (36) to contact with, and moves on, a refraction surface of a glass lens pattern (Lm) held in the glass lens pattern hold device so as to detect a change from a detection signal of a second position detection device (40) when the glass lens pattern (Lm) is engaged in metal fitting setting holes (104-107) as a relationship between a glass lens pattern circumferential shape and a hole position in accordance with a detection signal from the second position detection device (40).
