    • An apparatus for measuring the shape of a frame of spectacles is provided wherein the shape of a frame is measured with a measuring element which is held in contact with a groove in a rim of the frame while being moved along the groove. To accurately position the measuring element with respect to the groove of the frame before the start of measurement, a positioning device is provided which moves the measuring element horizontally toward the frame, presses the measuring element against the frame with a biasing force, and positions the measuring element at a measurement position. Further, to permit smooth vertical movement of the measuring element and to achieve accurate shape measurement, a thrust device is provided which pushes the lower end face of a measuring element supporting shaft upward at a location displaced from the axis of the shaft. To accurately position the measuring element for accurate shape measurement, the measuring element supporting shaft has a projection located between the measuring element and intervening mechanism. Further, to reliably hold the frame with ease and to prevent deformation of the same, a turning mechanism is provided for turning at least one of two holding members parallel to the plane of the frame rim, the holding members contacting the upper and lower portions, respectively, of the frame to thereby hold the frame.
    • 提供了一种用于测量眼镜架形状的装置,其中框架的形状是用测量元件测量的,该测量元件在沿着凹槽移动的同时与框架的边缘中的凹槽保持接触。 为了在测量开始之前将测量元件相对于框架的凹槽精确地定位,提供了一种定位装置,其将测量元件水平地朝向框架移动,将测量元件以偏置力压靠在框架上, 测量位置处的测量元件。 此外,为了允许测量元件的平滑的垂直运动并且实现精确的形状测量,提供了一种推力装置,其将测量元件支撑轴的下端面向上移动到偏离轴的轴线的位置。 为了准确地定位测量元件以进行精确的形状测量,测量元件支撑轴具有位于测量元件和中间机构之间的突起。 此外,为了容易地保持框架并且防止其变形,设置有用于使平行于框架边缘的平面的两个保持构件中的至少一个转动的转动机构,保持构件与上部和下部接触, 分别支持该帧,从而保持该帧。
