Eyeglass-frame-shape measuring device and eyeglass-lens processing apparatus having the same |
摘要 |
<p>An eyeglass-frame-shape measuring device (240) for measuring a lens frame shape of an eyeglass frame has a holding mechanism (200) for holding the frame (F) in a predetermined condition, a feeler (280) movable while being kept in contact with a frame groove of the frame (F) held by the holding mechanism, a measuring mechanism for obtaining information (rn,ϑ) on radius vector of the frame based on an amount of movement of the feeler (280), a moving mechanism having a first motor for moving the feeler (280) in a direction of the radius vector of the frame, and a control mechanism for variably controlling driving of the first motor during measurement based on the information on the radius vector obtained by the measuring mechanism.</p> |
