Description
【考案の詳細な説明】 本考案は、レンズ保持装置に関する。[Detailed explanation of the idea] The present invention relates to a lens holding device.
本考案のレンズ保持装置は、たとえばレンズメーターに
おけるレンズ保持部に適用して効果があるが、そのよう
な用途に限られるものではない。The lens holding device of the present invention is effective when applied to a lens holding portion in a lens meter, for example, but is not limited to such use.
レンズメーターにおいては、レンズの光軸位置及び乱視
軸方向の印を付けるための軸材装置奮有するが、その軸
材に際しては、レンズの光軸を軸材部材の位置に合致さ
せる作業と同時に、乱視軸の方向も揃える作業が必要に
なる。A lens meter has a shaft member device to mark the optical axis position and astigmatism axis direction of the lens, but when preparing the shaft member, at the same time, it is necessary to align the optical axis of the lens with the position of the shaft member. It is also necessary to align the directions of the astigmatism axes.
このためには、レンズは保持装置上で回転させられるの
であるが、レンズと保持部材との間の摺動のために、レ
ンズが傷つけられる恐れがあった。For this purpose, the lens is rotated on the holding device, but there is a risk that the lens may be damaged due to the sliding movement between the lens and the holding member.
本考案は、このような問題を解決できるレンズ保持装置
を提供することを目的とするものであって、その構成上
の特徴として挙げられる点は、レンズ台及びレンズ押え
の両方を回転自在に構成したことである。The purpose of the present invention is to provide a lens holding device that can solve these problems, and its structural feature is that both the lens stand and the lens holder are configured to be freely rotatable. That's what I did.
以下、本考案の一実施例を図について説明すると、１は
中空基材であって、レンズメーターの場合には内部にタ
ーゲット等が配置される。Hereinafter, one embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a hollow base material, and in the case of a lens meter, a target or the like is placed inside.
基材１には軸受２を介して中空筒状のレンズ台３が回転
自在に支持されており、レンズ台３の先端は、截頭円錐
形に形成されてレンズ支持部３ａ’に構成する。A hollow cylindrical lens stand 3 is rotatably supported on the base material 1 via a bearing 2, and the tip of the lens stand 3 is formed into a truncated cone shape and constitutes a lens support portion 3a'.
レンズ押え４は、支持部材５上に軸受６を介して回転自
在に支持されており、その先端にはレンズ台３のレンズ
支持部３ａに対向するパッド４ａを有する。The lens holder 4 is rotatably supported on the support member 5 via a bearing 6, and has a pad 4a at its tip facing the lens support portion 3a of the lens stand 3.
支持部材５は公知の構造により、基材１に対し矢印方向
に移動可能であり、レンズ７はレンズ台３のレンズ支持
部３ａとパッド４ａとの間に図示のように保持される。The support member 5 is movable in the direction of the arrow with respect to the base material 1 by a known structure, and the lens 7 is held between the lens support portion 3a of the lens stand 3 and the pad 4a as shown in the figure.
本考案においては、レンズ台とレンズ押えとが回転自在
であるので、レンズを回転させる場合に、これらの部材
とレンズとの間に摺動が生じず、したがってレンズに傷
がつく恐れがない。In the present invention, since the lens stand and the lens holder are rotatable, no sliding occurs between these members and the lens when the lens is rotated, so there is no risk of the lens being scratched.
