(57) [Summary] [Purpose] When foreign matter such as sand or dust enters the eyes, we try to remove the foreign matter with a clean gauze and open the eyelid toward the Isogo plane mirror or concave mirror. Check past
When it is difficult to remove, the magnifying glass is stacked on the flat mirror or concave mirror to check and remove it.However, the present invention aims to eliminate the difficulty and troublesomeness of stacking the magnifying glass on the flat mirror or concave mirror. It is a thing. Therefore, the present invention is a biconvex lens mirror in which a reflecting surface as a concave mirror is provided on one spherical surface of a biconvex lens. [Effect] In the biconvex lens mirror of the present invention as described above, the original focal position of the reflecting surface provided as a concave mirror is clearly moved closer to the reflecting surface by the refracting action of the biconvex lens, and the focal length is shortened. The biconvex lens mirror is characterized in that an object standing upright on the optical axis within the shortened focal length is observed as a dramatically magnified upright virtual image.

本考案は、我々の目に砂や塵芥等が入つた時にその確認・除去に便利な両凸レ ンズ鏡に関するものである。 The present invention relates to a biconvex lens mirror which is convenient for confirming and removing sand, dust, etc. that enter our eyes.
【０００２】[0002]
従来、我々は目に砂や塵芥等の異物が入つた時にはいそぎ平面鏡や凹面鏡に向 かつて瞼を開き清潔なガーゼ等で異物を除去しようとするが、異物が微小過ぎて 確認・除去できない時は平面鏡や凹面鏡に更に拡大鏡のレンズを重ね持つて漸く 確認・除去するものであつた。 Conventionally, when foreign matter such as sand or dust enters the eyes, we try to remove the foreign matter with a clean gauze by opening the eyelid toward the flat mirror or concave mirror, but when the foreign matter is too small to confirm and remove it. The lens of the magnifying glass was overlaid on the plane mirror or concave mirror to confirm and remove it.
【０００３】[0003]
しかし、片方の手に清潔なガーゼ等を持ちもう一方の手に平面鏡や凹面鏡に更 に拡大鏡のレンズを重ね持つて異物の確認・除去を行うのは極めて困難なことで あり、又常時それらのものを揃え置くのも甚だ困難なことである。 However, it is extremely difficult to check and remove foreign matter by holding a clean gauze in one hand and a flat mirror or a concave mirror in the other hand, and a magnifying glass lens over the other hand. It is very difficult to put things together.
【０００４】 そこで本考案は、両凸レンズの１球面に凹面鏡としての反射面を設けて両凸レ ンズと凹面鏡との一体化を図り、それらの困難を解消しようとするものである。In view of this, the present invention intends to eliminate the difficulties by providing a reflecting surface as a concave mirror on one spherical surface of a biconvex lens to integrate the biconvex lens and the concave mirror.

本考案を図面について詳述すると、先ず図１に示す従来からの曲率半径をγと する凹面鏡１の焦点３より鏡面に近い光軸２上に直立する物体ＡＢが、焦点３と 物体ＡＢの頭部Ａとを結ぶ直線の延長線と、同じく物体ＡＢの頭部Ａより光軸２ に平行状の直線が鏡面に交わる点のＣを結ぶ直線ＡＣの鏡面への入射角に等しい 反射角の直線ＣＤの延長線との交点Ａ１より光軸２上に垂直に下りたＡ１Ｂ１が 正立の拡大虚像として観察されるのを作図したものである。The present invention will be described in detail with reference to the drawings. First, an object AB standing upright on an optical axis 2 closer to the mirror surface than a focus 3 of a concave mirror 1 having a radius of curvature γ shown in FIG. A straight line having a reflection angle equal to the angle of incidence on the mirror surface of the straight line AC connecting the point A of the head A of the object AB and the point C where the straight line parallel to the optical axis 2 intersects the mirror surface. This is a diagram in which A 1 B 1 vertically descending on the optical axis 2 from the intersection A 1 with the extension line of the CD is observed as an upright enlarged virtual image.
【０００６】 次に図２に示す本考案の両凸レンズ鏡は、両凸レンズ４の１球面が図１の凹面 鏡１と同一の曲率半径γの球面に凹面鏡としての反射面５を設けたものである。Next, the biconvex lens mirror of the present invention shown in FIG. 2 is one in which one spherical surface of the biconvex lens 4 has the same curvature radius γ as the concave mirror 1 of FIG. 1 and a reflecting surface 5 as a concave mirror is provided. is there.
【０００７】 さて、図２に於て反射面５の焦点７は同一曲率半径γの図１の凹面鏡１の焦点 ３と同一の焦点距離であるべきはずが、両凸レンズ４の屈折作用によって明らか に反射面５に近ずいて本来の反射面５の焦点距離を短縮し、その短縮が短縮焦点 距離内の光軸６上に図１と全く同様の配置で直立する同一の物体ＡＢを、焦点７ と物体ＡＢの頭部Ａとを結ぶ直線の延長線と、同じく物体ＡＢの頭部Ａより光軸 ６に平行状の直線が反射面５に交わる点のＥを結ぶ直線ＡＥの反射面５への入射 角に等しい反射角の直線ＥＦの延長線との交点Ａ２より光軸６上に垂直に下りた Ａ２Ｂ２が飛躍的に拡大された正立の虚像として観察される本考案の特徴を作図 図示したものである。Now, in FIG. 2, the focal point 7 of the reflecting surface 5 should have the same focal length as the focal point 3 of the concave mirror 1 of FIG. 1 having the same radius of curvature γ, but it becomes clear by the refracting action of the biconvex lens 4. The focal length of the original reflecting surface 5 is shortened by approaching the reflecting surface 5, and the shortening is shortened. The same object AB standing upright on the optical axis 6 within the focal length in exactly the same arrangement as in FIG. To the reflection surface 5 of the straight line AE connecting the point E at which the straight line parallel to the optical axis 6 intersects the reflection surface 5 from the head A of the object AB and the head A of the object AB. A 2 B 2 vertically descending on the optical axis 6 from the intersection A 2 with the extension line of the straight line EF having a reflection angle equal to the incident angle of is observed as a dramatically enlarged erect virtual image of the present invention. It is a diagram showing the features.

このような本考案の両凸レンズ鏡は、単に目に砂や塵芥が入つた時の使用にと ゞまらず、女性の化粧時に男性の髯剃時に或はコンタクトレンズの装着にと広汎 な用途が加わり、高齢化の進む現代に於ては人々の老化に伴う視力の底化を補う 重要な必需品でもある。 Such a biconvex lens mirror of the present invention has a wide range of uses, not only for use when sand or dust enters the eyes, but also for makeup of women, when shaving men, or when wearing contact lenses. With the advent of the aging society, it is an important necessities to compensate for the deterioration of the visual acuity caused by the aging of people in the modern age.
【０００９】 また、本考案の両凸レンズ鏡は反射面５を適宜に被覆保護しケース等に収納し て携帯するのが便利であり、又本考案の両凸レンズ鏡をレンズの中心に於て光軸 ６に垂直な平面で片平凸レンズと反射面５を含む片平凸レンズとに２分割し、両 者を蝶番連結等して拡大鏡を必要とする時には片平凸レンズのみを使用し両凸レ ンズ鏡を必要とする時には両者を重ね使用するようにしても便利である。In addition, the biconvex lens mirror of the present invention is convenient to cover and protect the reflecting surface 5 appropriately, and to store the biconvex lens mirror in a case or the like for carrying. When a magnifying glass is needed by hinge-linking the two into a plano-convex lens and a plano-convex lens including the reflecting surface 5 on a plane perpendicular to the axis 6, only use the plano-convex lens and use the bi-convex lens. It is also convenient to use both when they are needed.
【００１０】 なお、本考案の図２に示す作図に於ては飛躍的な拡大の正立の虚像Ａ２Ｂ２の 頭部Ａ２の交点を求める２直線（光線の意である。）の両凸レンズ４内通過時の 屈折作用は無視するものとする。（影響は微少である。）It should be noted that in the drawing shown in FIG. 2 of the present invention, two straight lines (meaning light rays) for obtaining the intersection of the head A 2 of the erecting virtual image A 2 B 2 with a dramatic expansion. Refractive action when passing through the biconvex lens 4 is neglected. (The impact is minimal.)

本考案を図面について詳述すると、先ず図１に示す従来からの曲率半径をγと する凹面鏡１の焦点３より鏡面に近い光軸２上に直立する物体ＡＢが、その頭部 Ａより凹面鏡１と光軸２との交点Ｃに至る光線ＡＣの鏡面への入射角に等しい反 射角で反射する反射光線ＣＤの点線図示の延長線と、焦点３と物体ＡＢの頭部Ａ とを結ぶ光線３Ａの点線図示の延長線との交点Ａ１より光軸２上に垂直に下りる Ａ１Ｂ１が物体ＡＢの正立の拡大虚像として観察できるのを作図で示したもので ある。The present invention will be described in detail with reference to the drawings. First, an object AB standing upright on an optical axis 2 closer to the mirror surface than a focus 3 of a conventional concave mirror 1 having a radius of curvature γ shown in FIG. And the optical axis 2 and a ray C connecting the focal point 3 and the head A of the object AB with the extended line of the reflected ray CD reflected at the reflection angle equal to the angle of incidence on the mirror surface of the ray AC reaching the intersection C. The drawing shows that A 1 B 1 vertically descending on the optical axis 2 from the intersection A 1 with the extension of the dotted line of 3A can be observed as an upright enlarged virtual image of the object AB.
【０００６】 次に図２に示す本考案の両凸レンズ鏡は、両凸レンズ４の１球面が図１の凹面 鏡１と同一の曲率半径γの球面に凹面鏡としての反射面５を設けて両凸レンズと 凹面鏡との一体化を図ったものである。Next, in the biconvex lens mirror of the present invention shown in FIG. 2, a biconvex lens 4 has a single spherical surface having the same radius of curvature γ as the concave mirror 1 of FIG. And the concave mirror.
【０００７】 さて、図２に於て反射面５の焦点７は同一曲率半径γの図１の凹面鏡１の焦点 ３と同一の焦点距離であるべきはずが、両凸レンズ４の屈折作用によって明らか に反射面５に近ずいて本来の反射面５の焦点距離を短縮し、その短縮が短縮焦点 距離内の光軸６上に図１と全く同一の関係位置に直立する物体ＡＢを、その頭部 Ａより反射面５と光軸６との交点Ｅに至る光線ＡＥの反射面５への入射角に等し い反射角で反射する反射光線ＥＦの点線図示の延長線と、焦点７と物体ＡＢの頭 部Ａとを結ぶ光線７Ａの点数図示の延長線との交点Ａ２より光軸６上に垂直に下 りるＡ２Ｂ２が物体ＡＢの飛躍的に拡大された正立の虚像として観察できるのを 作図で示したものである。Now, in FIG. 2, the focal point 7 of the reflecting surface 5 should have the same focal length as the focal point 3 of the concave mirror 1 of FIG. 1 having the same radius of curvature γ, but it becomes clear by the refracting action of the biconvex lens 4. An object AB standing upright in exactly the same relational position as in FIG. 1 on the optical axis 6 within the focal length is shortened by shortening the focal length of the original reflecting surface 5 while approaching the reflecting surface 5.
