中心間距離測定装置。[Claims for Utility Model Registration] A fixed stage having a reference abutting surface against which the outer surfaces of lens frames on both sides of an eyeglass frame can each come into contact; a fixing pin provided on the fixed stage so as to be freely movable in a direction substantially perpendicular to the contact surface and capable of abutting against the inner surface of one lens frame of the eyeglass frame; and a fixed pin provided on the fixed stage substantially parallel to the reference contact surface. a movable stage provided movably in a direction; and a movable stage provided immovably in a direction substantially parallel to the reference abutment surface and freely movable in a direction substantially perpendicular to the reference abutment surface. a movable pin that can come into contact with the inner surface of the other lens frame of the eyeglass frame; a movable biasing means that constantly applies a movable force to the movable stage in a direction that causes the movable pin to move away from the fixed pin; and the reference abutment. An apparatus for measuring a distance between geometric centers of eyeglass frames, comprising a distance measuring means for measuring a distance between the movable pin and the fixed pin in a direction substantially parallel to a plane.
