摘要:
A spectacle lens frame shape measuring apparatus includes a holding device including upper pins and lower pins respectively holding upper rims and lower rims of frames for a spectacle lens, the upper pins holding the frames at different positions in a right-left direction from the positions at which the lower pins hold the frames and being placed at a same height as the lower pins in a vertical direction, a probe brought into contact with lens fitting grooves of the frames held by the holding device, a swinging mechanism swinging the holding device around a predetermined virtual axis, and a calculation controller calculating an axial shift amount or angle of the frames held by the holding device on the basis of a carved angle of the frames and an inclination angle of any one of the upper and lower rims, and correcting a shape of the frames obtained by the probe in accordance with the calculated axial shift amount or angle.
