(57) [Summary] (Correction) [Purpose] To provide a lens that doubles as a bookmark sandwiched between books and the like. [Structure] Two or more lenses are set on the same surface of a housing (3) and set according to the pupil distance of a person. Alternatively, the lens (1) and the lens (2) may be integrally molded and attached to the housing (3).
Description
【0001】 レンズ(1)とレンズ(2)を同一面(筐体(3)と称する)に併設した「しお りレンズ」であり、筐体(3)にレンズと一体成形し或は別に用意した筐体(3 )にレンズ穴(4)とレンズ穴(5)を穿ち、レンズ(1)及びレンズ(2)の 外周周縁部(6)を筐体(3)に接着する。書籍等の間に挟み、「しおり」とし て利用する他に文字等を拡大して見ることが出来る様に設定した。レンズ(1) とレンズ(2)の倍率を各々変えて強弱二種類のレンズを設け、利用者の便を計 った。又レンズ(1)とレンズ(2)を同一倍率に設定すれば、立体写真用立体 視鏡として利用出来る「しおりレンズ」である。A “shiori lens” in which a lens (1) and a lens (2) are provided side by side on the same surface (referred to as a housing (3)). The housing (3) is integrally molded with the lens or separately. The prepared housing (3) is provided with a lens hole (4) and a lens hole (5), and the outer peripheral edge portions (6) of the lens (1) and the lens (2) are bonded to the housing (3). It is set so that it can be sandwiched between books and used as a “bookmark” and that characters can be enlarged and viewed. Two types of lenses, strong and weak, were installed by changing the magnification of lens (1) and lens (2) respectively, and the convenience of the user was measured. Also, if the lens (1) and the lens (2) are set to the same magnification, it is a “bookmark lens” that can be used as a stereoscopic stereoscopic microscope.
書籍の「しおり」として利用すると同時に、文字等の拡大鏡としても利用する強 弱二つのレンズを有しているので利用に便である。又両レンズを同一倍率として 設定すれば、立体視鏡として利用出来る。 It is convenient to use because it has two lenses, one for strength and one for use as a magnifying glass for characters, as well as being used as a "bookmark" for books. If both lenses are set to have the same magnification, it can be used as a stereoscope.
【0002】[0002]
拡大鏡(ルーペ)はガラス製又は合成樹脂製のものはあるが、「しおり」として はあまり利用されていない。フレネルレンズを応用した合成樹脂製しおりのレン ズはあるが、強弱二つ以上のレンズを併設した「しおり」兼用のレンズは無く立 体視鏡として利用出来るしおりレンズも無い。 Magnifying glass (loupe) is made of glass or synthetic resin, but it is not often used as a "bookmark". There is a synthetic resin bookmark lens that uses a Fresnel lens, but there is no bookmark lens that can be used as a stereoscope because there is no lens that can be used as a “bookmark” that has two or more lenses with different strengths.
【0003】[0003]
強弱二つ以上のレンズ面を有し、各々の倍率を持ったレンズを一体して成形する 拡大鏡として利用者の便を計った。両レンズを同一倍率のレンズとすれば、立体 視鏡レンズとしても利用することができる。 It was convenient for the user as a magnifying glass, which has two or more lens surfaces with different strengths, and integrally molds lenses with different magnifications. If both lenses have the same magnification, they can be used as a stereoscopic lens.
【0004】[0004]
筐体(3)に用途に合わせた倍率のレンズを取り付ける。又レンズ及び筐体一体 成形の「しおりレンズ」にあっては、用途に合わせてレンズ金型を交換すること によってレンズの倍率を変えることが出来る。 A lens with a magnification suitable for the application is attached to the housing (3). Also, in the case of a "bookmark lens" in which the lens and the housing are integrally molded, the magnification of the lens can be changed by changing the lens mold according to the application.
【0005】[0005]
筐体(3)の同一面に二つのレンズを設定したので、強弱の倍率のレンズとして 又立体視鏡レンズとして利用できる。 Since the two lenses are set on the same surface of the housing (3), it can be used as a lens having a different magnification and a stereoscopic lens.
【0006】[0006]
以下、本考案の実施例について説明する。 (ア)筐体(3)同一面に瞳孔距離を合わせて二つのレンズを併設する。 (イ)筐体(3)にレンズ(1)及びレンズ(2)の異なった倍率のレンズを取 り付ける。 (ウ)筐体(3)にレンズ(1)及びレンズ(2)は同一倍率にて取り付ける。 Embodiments of the present invention will be described below. (A) Housing (3) Two lenses are provided side by side with the pupil distance aligned on the same plane. (A) Mount lenses (1) and (2) with different magnifications to the housing (3). (C) The lens (1) and the lens (2) are attached to the housing (3) at the same magnification.
【0007】[0007]
(ア)強弱二つ以上のレンズを有する「しおりレンズ」である。 (イ)二つのレンズを同一倍率とすれば、立体視鏡となる。 (ウ)従来通り筐体(3)に「リボン通し穴」を設けた。 (エ)筐体(3)に「クリップ」を設けた。 (A) A “bookmark lens” having two or more lenses of different strengths. (B) If the two lenses have the same magnification, it becomes a stereoscopic endoscope. (C) A “ribbon through hole” was provided in the housing (3) as in the conventional case. (D) A “clip” was provided on the housing (3).
