従来の技術の説明に先立ち、先ず、レーザー光線を使用する墨出し装置の原理 について説明する。判りやすくするため、非点収差用レンズとして良く知られて いるシリンドリカルレンズを用いてその原理につて説明する。図７において、レ ーザー光線発光素子１から放射されたレーザー光線はコリメーションレンズ２に より平行光線になされ、非点収差を用いるカマボコ状のシリンドリカルレンズ３ に入射される。このシリンドリカルレンズは単一方向（ｘ方向）（水平方向）に のみ凸レンズとして働いて水平方向の光は収束されるが、他の方向（ｙ方向）（ 垂直方向）の形状は単なる直線の棒に過ぎないので、光は垂直方向には収束され ない。それ故、Ｂ点では縦（ｙ方向）に一本の線として、またＡ点では横（ｘ方 向）に一本の線として集光される。そして、もし、このシリンドリカルレンズ３ への入射光線の光軸に対する直交断面が、第７図Ｃ点に示すように円形の場合、 入射光線はシリンドリカルレンズ３の働きによりＡ点及びＢ点においては一本の 直線になる。そして点Ｃと点Ｂとの間では縦に長細い円となり、点ＣとＡ点との 間では横に長細い円となる。そして、このようにして作られた一本の直線は極め て短く、墨出しに使用することは難しい。レーザー光線による墨出し装置は、こ のように非点収差レンズを使用することにより、一本の細い線として光線が収束 されるという原理を利用するものである Prior to the description of the related art, first, the principle of a marking device using a laser beam will be described. For the sake of clarity, the principle will be described using a cylindrical lens well known as an astigmatism lens. In FIG. 7, a laser beam emitted from a laser beam emitting element 1 is converted into a parallel beam by a collimation lens 2 and is incident on a cylindrical lens 3 having an astigmatism and using astigmatism. This cylindrical lens works as a convex lens only in a single direction (x direction) (horizontal direction) and converges the light in the horizontal direction, but the shape in the other direction (y direction) (vertical direction) becomes a simple straight rod. Light is not converged vertically. Therefore, the light is condensed as a single line vertically (in the y direction) at point B, and as a single line horizontally (in the x direction) at point A. If the cross section orthogonal to the optical axis of the light beam incident on the cylindrical lens 3 is circular as shown at point C in FIG. 7, the incident light beam is one point at points A and B due to the function of the cylindrical lens 3. It becomes a straight line of a book. Then, between the points C and B, a vertically elongated circle is formed, and between the points C and A, a horizontally elongated circle is formed. And one straight line made in this way is extremely short, and it is difficult to use it for marking. A laser beam marking device uses the principle that light rays are converged as a single thin line by using an astigmatism lens in this way.
【０００３】 さて、実際のレーザー光線使用の墨出し装置においては、非点収差用に用いる レンズは、シリンドリカルレンズではなく、図８（ａ）（ｂ）（ｃ）に示すよう に断面円形の棒状のロッドレンズ４である。このようなロッドレンズを使用する ことにより墨出し用の長い直線が容易に得られ、このレーザー光線を建築現場の 建築物の壁面、床面や天井面に投射して墨出しを行う。図８（ｂ）はレーザー光 線発光素子１、光線収束用の非球面レンズ２とロッドレンズ４の配置状態を示し 、非球面レンズ２とロッドレンズ４との距離ｆ２が長すぎて、ロッドレンズ４の 位置より手前で非球面レンズ２により光線が収束したために光線による直線の幅 が広がっている様子を示す。図８（ｃ）は距離（ｆ１）及び（ｆ２）が適切に調 整されて、投射光線が幅の極めて狭い直線ｍになっていて、墨出しに使用できる 様子を示している。In an actual blackout device using a laser beam, the lens used for astigmatism is not a cylindrical lens but a rod-shaped lens having a circular cross section as shown in FIGS. 8 (a), 8 (b) and 8 (c). The rod lens 4. By using such a rod lens, a long straight line for inking can be easily obtained, and this laser beam is projected on the wall, floor or ceiling of the building at the construction site to perform inking. FIG. 8B shows the arrangement of a laser beam emitting element 1, an aspheric lens 2 for converging light rays, and a rod lens 4. The distance f2 between the aspheric lens 2 and the rod lens 4 is too long, and the rod lens This shows a state in which the width of the straight line formed by the light rays is widened because the light rays are converged by the aspherical lens 2 before the position 4. FIG. 8C shows a state in which the distances (f1) and (f2) are appropriately adjusted, and the projection light is a very narrow straight line m, which can be used for blackout.
【０００４】 その際、従来はレーザー光線発光素子１、非球面の第１レンズ２及びロッドレ ンズ４の取付方は複雑な構成であり、また、レーザー光線発光素子１からレンズ ２までの距離ｆ１の調整、また、レンズ２からロッドレンズ４までの距離ｆ２の 調整を行うために非常に複雑な構成にして行っていた。また、レーザー光線の光 線軸に対するロッドレンズ４の角度を調整するにも非常に複雑な構成にしていた 。そのため装置の組立や調整が複雑になり、然も墨出し精度が出しにくく、値段 も高くなるという問題があった。[0004] At that time, conventionally, the mounting method of the laser beam emitting element 1, the aspheric first lens 2 and the rod lens 4 has a complicated structure, and the distance f1 from the laser beam emitting element 1 to the lens 2 is adjusted. In addition, in order to adjust the distance f2 from the lens 2 to the rod lens 4, a very complicated configuration is used. Also, the configuration of the rod lens 4 with respect to the optical axis of the laser beam is very complicated to adjust the angle. As a result, the assembly and adjustment of the apparatus become complicated, and it is difficult to obtain the ink-marking accuracy, and the price increases.

【００１７】 通常、発光素子１にはその特性にバラツキがあり、発光素子１と非球面レンズ ８との間の距離ｆ１、非球面レンズ８とロッドレンズ４との間の距離ｆ２を調整 する必要がある。この実施例では、図４に示すように距離ｆ２の方は略固定して おき、ｆ１の方を調整することにより全体を調整するようにしている。即ち、発 光素子１と非球面レンズ８との距離ｆ１は、固定具７の雌ネジ７ｃと中間連結具 ６の雄ネジ６ｂをの締め付け具合を調整したり、また中間連結具６の内部の雌ネ ジ６ｃと発光素子ホルダー５の雄ネジ５ｃとの螺合具合を調整することにより、 図７ｃに示すようにロッドレンズ４に丁度焦点が結ぶように精密且つ容易に調整 できる。そして、この調整が終わると、この調整が振動等で変化しないように、 中間連結具６の側面に設けられた固定用ネジ孔６ｄ，６ｄ’及び固定具７の側面 に設けられた固定用ネジ孔７ｇ，７ｇ’にそれぞれ固定用ネジ６ｅ，６ｅ’及び 固定用ネジ７ｈ，７ｈ’を締め付けて固定する。Normally, the characteristics of the light emitting element 1 vary, and it is necessary to adjust the distance f 1 between the light emitting element 1 and the aspheric lens 8 and the distance f 2 between the aspheric lens 8 and the rod lens 4. There is. In this embodiment, as shown in FIG. 4, the distance f2 is substantially fixed, and the whole is adjusted by adjusting the f1. That is, the distance f1 between the light emitting element 1 and the aspherical lens 8 can be adjusted by tightening the female screw 7c of the fixture 7 and the male screw 6b of the intermediate connector 6 or by adjusting the inside of the intermediate connector 6. By adjusting the degree of screwing between the female screw 6c and the male screw 5c of the light emitting element holder 5, the rod lens 4 can be precisely and easily adjusted so that the focus is just focused on the rod lens 4 as shown in FIG. 7c.

The fixing screws 6e and 6e 'and the fixing screws 7h and 7h' are tightened and fixed to the holes 7g and 7g ', respectively.
【００１８】 次に、発光素子１から非球面の第１レンズ８を通過して来る光線軸に対して非 点収差用のロッドレンズ４の長手方向の軸の角度を精密調整する必要がある。も しこの角度が適切に調整出来ていない場合には投射線の幅が投射線の両端では一 方は狭く、他方は広くなったり、また投射線がぼやけた所が現れる。それ故、こ のロッドレンズ４の長手方向の軸の角度を適切に調整しなければならない。この 軸の角度は、図５に示すように次のように行われる。即ち、レンズ載置具１０の 先端の尖った支持用突起部１０ｂは、固定具７の支持用凹状部７ｄに嵌合して揺 動自在に支持されているので、角度調整用ネジ１３ａ及び１３ｂの締め付け具合 を調整することによりロッドレンズ４の軸の角度を調整することができる。尚、 その際固定具７とレンズ載置具１０の間に且つ調整用ネジ１３ａ、１３ｂに挿入 して弾性バネを配置しておけば、角度の調整は一層スムーズに行える。尚また、 図５は第１レンズ８を通過して来る光線軸に対してロッドレンズ４の長手方向の 軸の角度を調整する様子を説明することを趣旨としているので、発光素子ホルダ ー５、中間連結具６、固定具７等の内部構造は省略して示してある。Next, it is necessary to precisely adjust the angle of the longitudinal axis of the astigmatism rod lens 4 with respect to the ray axis passing from the light emitting element 1 through the aspheric first lens 8. If this angle is not properly adjusted, the width of the projection line will be narrower at one end and wider at the other end of the projection line, or the projection line will appear blurred. Therefore, the angle of the longitudinal axis of the rod lens 4 must be appropriately adjusted. The angle of this axis is determined as follows, as shown in FIG. In other words, the support projection 10b having a sharp tip of the lens mounting device 10 is fitted to the support concave portion 7d of the fixing device 7 and supported swingably, so that the angle adjusting screws 13a and 13b are provided.
