Abstract: In an apparatus for measuring a configuration of each of a pair of lens frames (4a, 4b) of a spectacle framework (3), a measuring element (230) is arranged for horizontal and vertical movement relative to the lens frames fixedly held by a holding device (100). The measuring element is movable angularly about an optional reference point (O) within one of the lens frames, along an inner periphery of the lens frame, while causing the measuring element to be in contact with the inner periphery of the lens frame. A first detector unit (224) detects horizontal straight displacement (r) of the measuring element from the reference point. A second detector unit (233) detects vertical straight displacement (z) of the measuring element from the reference point. A third detector unit (209) detects an angle (.theta.) of the angular movement of the measuring element about the reference point.
