Description
【０００１】[0001]
本考案は、倍率変更可能な双眼鏡に関する。 The present invention relates to binoculars with variable magnification.
【０００２】 この種双眼鏡は、対物レンズ系と接眼レンズ系との間に位置するリレーレンズ を光軸上に沿って移動する謂わゆるズームレンズ光学系から成り立つ。Such binoculars comprise a so-called zoom lens optical system which moves a relay lens located between an objective lens system and an eyepiece lens system along an optical axis.
【０００３】 本考案の変倍双眼鏡も基本的にはこの構成を具備する。The variable power binoculars of the present invention basically have this configuration.
【０００４】[0004]
上記ズームレンズ光学系によって、双眼鏡の倍率変化を与える場合、対物レン ズ系と接眼レンズ系との間で光軸上を移動させるリレーレンズは、各種収差を除 去し、また連続的な倍率変化を行なわせるために、リレーレンズを複数群で構成 し、それらを相関的に動かすといった複雑な構成と機構が余儀なくされ、その結 果として、視界が狭くなる傾向を否定できない。 When the zoom lens optical system changes the magnification of the binoculars, a relay lens that moves on the optical axis between the objective lens system and the eyepiece system removes various aberrations and continuously changes the magnification. In order to achieve this, a complicated configuration and mechanism, such as configuring the relay lenses in a plurality of groups and moving them in a correlated manner, is inevitable, and as a result, the tendency of narrowing the field of view cannot be denied.
【０００５】 また、別の手段としては、単一のリレーレンズの移動とともに、接眼レンズ系 をも関連して動かすといった機構的な設計が要求された。何れにしても、こうし たレンズ系の構成によれば、変倍目的のために、レンズ系に高価な素材を使用し たり、複雑なレンズ構成やレンズ系に対して関連的な移動を行なわせる必要から 、視界が狭小となったり、重量が大きく嵩張るものとなって、小型化に困難を来 たし、その結果、生産価格も高騰するのを避けられなかった。As another means, a mechanical design has been required to move the eyepiece system in conjunction with the movement of the single relay lens. In any case, according to such a configuration of the lens system, an expensive material is used for the zooming purpose, or a complicated movement is performed for a complicated lens configuration or the lens system. This necessitated the narrowing of the field of view and the large and bulky weight, which made it difficult to miniaturize it, and as a result, the production price was inevitable.
【０００６】 図４及び図５によって、２群で構成されたリレーレンズを相関的に動かす従来 のズームレンズ光学系を具えた変倍双眼鏡のリレーレンズの動きを示す。FIGS. 4 and 5 show the movement of a relay lens of a variable power binocular provided with a conventional zoom lens optical system that moves a relay lens composed of two groups in a correlated manner.
【０００７】 符号７は対物レンズ系であり、符号８は接眼レンズ系である。これらの対物レ ンズ系と接眼レンズ系との間には、複数のプリズムを組み合わせた反転反射光学 系６が介在し（図中、符号Ｐとその両側の矢標で範囲を示した領域は、反転反射 光学系による光路長を現わす）、この反転反射光学系６と接眼レンズ系８との間 に、リレーレンズ９及び１０を光軸Ｘ−Ｘ上で動かすようにしてある。図４では 、最高倍率においてリレーレンズ９及び１０の夫々が相互に離れた位置を占め、 それらの位置を符号９′及び１０′で示してある。これに反し、これらの位置か らリレーレンズ９及び１０を互いに接近させ、これらリレーレンズ９及び１０が 最も接近した位置において、最低倍率が与えられる。即ち、この実例が示すよう に、リレーレンズは、２群から成り、それらを相互に離間させたり、接近させる ことで変倍の実を挙げているが、この場合、リレーレンズは複数構成となってお り、またこれらの相互離間や接近のために、鏡枠に対し機械的にも複雑な構造が 要求され、リレーレンズの重量やそれらの移動機構のための重量も加算されて、 双眼鏡の重量を増し、また場合によっては、双眼鏡の外形的な嵩を大きくする。Reference numeral 7 denotes an objective lens system, and reference numeral 8 denotes an eyepiece lens system. An inverted reflection optical system 6 combining a plurality of prisms is interposed between the objective lens system and the eyepiece lens system (in the figure, the area indicated by the reference sign P and the arrowheads on both sides of the optical system is indicated by a symbol P). The optical path length by the inverted reflection optical system is expressed), and the relay lenses 9 and 10 are moved on the optical axis XX between the inverted reflection optical system 6 and the eyepiece lens system 8. In FIG. 4, at the highest magnification, each of the relay lenses 9 and 10 occupies a position apart from each other, and their positions are indicated by reference numerals 9 'and 10'. On the contrary, the relay lenses 9 and 10 are moved closer to each other from these positions, and the lowest magnification is given at the position where the relay lenses 9 and 10 are closest. In other words, as shown in this example, the relay lens is composed of two groups, and the fact that the magnification is changed by moving them apart or approaching each other is mentioned. In this case, the relay lens has a plurality of configurations. In addition, a mechanically complex structure is required for the lens frame to separate and approach each other, and the weight of the relay lens and the weight for their moving mechanism are added. It adds weight and, in some cases, increases the external bulk of the binoculars.
【０００８】[0008]
本考案では、従来のこの種変倍双眼鏡における前記問題点を考慮し、主として 、視界が狭くなるのを防ぎ、広い視界をもたせ、而もリレーレンズの構成とその 移動機構を簡潔なものとして、軽量で小嵩な変倍双眼鏡を提供しようとするもの である。 In the present invention, in consideration of the above-mentioned problems in the conventional variable-magnification binoculars, mainly, a view is prevented from being narrowed, a wide view is provided, and a configuration of a relay lens and a moving mechanism thereof are simplified. It aims to provide lightweight and small-sized variable-power binoculars.
【０００９】 この為、連続的な倍率変化による連続合焦機能を排して、最高倍率と最低倍率 との２点においてのみ合焦機能を発揮させることで、リレーレンズの構成を簡略 化し、その移動のための機構を簡潔にして、軽量で小嵩な変倍双眼鏡とし、携行 使用上の利便を向上するとともに、生産価格の低廉化を図らうとするものである 。For this reason, the continuous focusing function based on a continuous magnification change is eliminated, and the focusing function is exhibited only at the two points of the highest magnification and the lowest magnification, thereby simplifying the configuration of the relay lens. The purpose is to make the mechanism for moving simple, lightweight and small-sized variable-power binoculars, to improve the convenience of carrying, and to reduce the production price.
【００１０】[0010]
上記の目的を達成するために、本考案では、反転反射光学系と接眼レンズ系と の間で光軸上を移動するリレーレンズを単一の発散レンズ若しくは、複合された 単一の発散レンズをもって構成し、その移動領域を、最高倍率においては、反転 反射光学系の光射出面に近接した位置に設定し、最低倍率においては、接眼レン ズ系の光入射面に近接した位置に設定するとともに、これら２点の限界移動位置 においてのみ合焦可能に構成した。 In order to achieve the above object, in the present invention, a relay lens moving on the optical axis between the inverting reflection optical system and the eyepiece lens system is provided with a single diverging lens or a combined single diverging lens. At the highest magnification, the moving area is set at a position close to the light exit surface of the inverting reflection optical system, and at the lowest magnification, it is set at a position close to the light incident surface of the eyepiece lens system. Focusing was possible only at these two limit movement positions.

The second prism may be combined with the second prism, and the light on the optical axis may be reflected in a vertical plane and emitted toward the eyepiece lens by each surface of the roof surface of the second prism.

It is preferable to use a single concave lens to reduce the weight and to make the movement light and smooth, and depending on the configuration of the objective lens system and the eyepiece lens system, it may be necessary to remove aberrations. , A plurality of groups.

In the drawing, reference numeral 11 denotes an objective lens system in which two lenses, a convex lens and a concave lens, are configured as one group. Is an eyepiece system composed of two groups in which a complex lens composed of two lenses, a convex lens on the front surface and a convex lens concave lens, is arranged on the rear surface.

The ridgeline 16 of the roof surface is arranged so as to be positioned in a vertical plane orthogonal to the incident optical axis XX 'so that the reflected light to be emitted is received by a part of the bottom surface 18 including the hypotenuse of the isosceles right triangle. And a second prism 14 composed of a right-angled triangular cone, which is reflected in a horizontal plane by each surface of the roof surface of the second prism 14 and reflects the light on the optical axis XX 'toward the eyepiece.

A single relay lens can achieve sufficient focusing results without the need for the means described above.

The dimensional design is made so as to occupy a position very close to the bottom surface 18 of the two prisms 14, thereby shortening the total length restricted by the length (X-Y ') on the optical axis as the binoculars. To help make it more compact.
