PROBLEM TO BE SOLVED: To provide a method of manufacturing a binocular loupe suitable for an operator by enabling a pupil position in an actual operation posture of each operator to be precisely and easily identified.SOLUTION: Strobe light is radiated from a work operation position P at a fingertip when an operator wearing a frame to which a loupe has not been attached performs operation in such a way as to face downward. Reflected light from the pupil of the operator is photographed by a camera 11 and the pupil position of the eye is identified by a photographed image. Based on a distance A from the work operation position P to a carrier lens and a distance B in a horizontal direction from a vertical line passing through the carrier lens to the work operation position P, downward installation angles r1 and r2 are determined when the loupe is installed into the carrier lens.COPYRIGHT: (C)2014,JPO&INPIT【課題】作業者個々による実際の作業体勢での瞳孔位置を正確且つ簡単に特定可能にすることで、作業者に適した双眼ルーペの製作方法を提供する。【解決手段】ルーペが未装着のフレームを着用した作業者が下向きに作業するときの手先の作業操作箇所Pからストロボ光を照射し、作業者の瞳孔からの反射光をカメラ11で撮影して、撮影画像から眼の瞳孔位置を特定する。作業操作箇所Pからキャリアレンズまでの距離Aと、キャリアレンズを通る鉛直線から作業操作箇所Pまでの水平方向での距離Bとでルーペをキャリアレンズに装着する際の下方装着角度r1、r2を決める。【選択図】図6
