Abstract:
1. A spectacle lens frame shape measuring apparatus, comprising: a holding device including upper holding pins and lower holding pins respectively holding upper rims and lower rims of spectacle lens frames, the upper holding pins holding the spectacle lens frames at different positions in a right-left direction from the positions at which the lower holding pins hold the spectacle lens frames and being placed at a same height as the lower holding pins in a vertical direction; a probe brought into contact with lens fitting grooves of the spectacle lens frames held by the holding device and configured to detect a shape of the spectacle lens frame; a holding device swinging mechanism swinging the holding device around a predetermined virtual axis; and a calculation controller configured to receive a detected result of the probe, the calculation controller being configured to calculate an axial shift amount or angle of the spectacle lens frames held by the holding device on the basis of a curved angle of the spectacle lens frames and an inclination angle of any one of the upper and lower rims, and correct the shape of the spectacle lens frames obtained by the probe in accordance with the calculated axial shift amount or angle by the calculation controller.
