Apparatus for measuring a lens frame configuration
 An apparatus for measuring a lens frame configuration is provided which comprises an apparatus body provided with a measuring reference surface, a frame holder movably retained by the apparatus body and adapted to hold right and left lens frames of an eyeglass frame so as to rotate and incline a holding plane of the lens frame with respect to the reference surface, a rotating device for rotating and inclining the frame holder, a measuring portion for measuring coordinates of each point in a circumferential direction of a V-shaped groove of the lens frame with respect to the measuring reference surface, and an arithmetic circuit for calculating an inclination of the lens frame in the V-shaped groove with respect to the reference surface from a result obtained by the measuring portion.
