FRAME SHAPE MEASURING INSTRUMENT.

摘要

An arithmetic control circuit (600) drives and controls a motor (209) on the basis of a measurement result by a measuring portion (300), and a frame holding device (100) is subjected to tilting rotation control so that the center line (503) of the measurement portion of a V-shaped groove (502) of a lens frame (501) is in parallel with a reference measurement plane SO. Coordinates of each point of the V-shaped groove (502) are sequentially measured by the measurement portion (300), and the shape of an eyeglass frame (501) is computed. <IMAGE>
