Zusammenfassung:To provide a head-mounted type loupe that can match imaging with a view line of a wearer, and can magnify a deep hole or a deep part of a small hole of an aperture diameter accurately and stably.SOLUTION: A head-mounted type loupe comprises: a convergence angle contraction member that has a pair of right and left first view line refractive members 22 and 22 refracting right and left view lines S and S to an inner side respectively, and a pair of right and left second view line refractive members 24 and 24 refracting forward each of view lines S and S refracted by the first view line refractive members 22 and 22; and further an optical axis refractive member 32 that is disposed between a magnifier 5 and the second view line refractive members 24 and 24, transmits forward each of the view lines S and S refracted by the second view line refractive members 24 and 24, refracts an optical axis of a camera member, and matches the optical axis thereof with one view line S. According to this configuration, a convergence angle θ of the view lines S and S can be made small, and thus, a deep part 62 of a deep hole 61 can be magnified, and the deep part 62 can be imaged with an eye line of a wearer.SELECTED DRAWING: Figure 6 【課題】装着者の視線と一致する撮像を行い得ると共に、深い穴や開口径の小さい穴の深部を正確かつ安定して拡大視できる頭部装着型ルーペを提供する。【解決手段】左右の視線S,Sを夫々内側へ屈折させる左右一対の第一視線屈折部材22,22と、該第一視線屈折部材22,22で屈折された各視線S,Sを前方へ屈折させる左右一対の第二視線屈折部材24,24とを有する輻輳角縮小部材を備え、さらに、拡大鏡5と第二視線屈折部材24,24との間に配設され、該第二視線屈折部材24,24で屈折された各視線S,Sを前方へ通過させると共に、カメラ部材の光軸を屈折させて一方の該視線Sと一致させる光軸屈折部材32を備える。かかる構成によれば、視線S,Sの輻輳角θを小さくできるから、深い穴61の深部62を拡大視できると共に該深部62を装着者の目線で撮像できる。【選択図】図6
