OPTICAL INSTRUMENT DEVICE USING EYEGLASS LENS AND ROUND LENS AS SUBJECT LENS

To abolish a lens stand widely used in an optical instrument device, dispense with the dimension in the vertical direction related to the stand and an eyeglass temple of an eyeglass frame, lower the floor of the device, and improve the reliability of the optical accuracy and the operability.SOLUTION: A frame holding mechanism 1 is formed of a frame member 7 slidable in an X-axis direction to a subject lens such as an eyeglass lens ML or a round lens inserted in a frame, and holding arm members 11a and 11b arranged symmetrically. The frame holding mechanism is disposed so as to cross an optical axis in an optical instrument, a temple MT of the eyeglass frame is held while being erected upward, and a movement operation in the X-axis direction is allowed.SELECTED DRAWING: Figure 2 【課題】光学機器装置において多用されてきたレンズ載置台を廃止して、載置台と眼鏡フレームの眼鏡ヅルに纏わる垂直方向の寸法を不要となし、装置の低床化を果すと共に、光学精度と操作性の信頼性の向上を果たす。【解決手段】枠入れされた眼鏡レンズＭＬや丸レンズ等の被検レンズに対するＸ軸方向へのスライド自在なフレーム部材７と対称的に配置された保持アーム部材１１ａ、１１ｂ等から構成された枠型保持機構１を、光学機器における光軸と交叉するよう配置し、眼鏡フレームのテンプルＭＴを上方に立ち上げたまま保持し、かつＸ軸方向への移動操作を可能とした。【選択図】図２
