Description

本発明は、分光蛍光光度計に係り、光源位置合せを容易に行い得る分光蛍光光度計用光源位置合わせ機構に関するものである。   The present invention relates to a spectrofluorometer, and more particularly to a light source alignment mechanism for a spectrofluorometer that can easily perform light source alignment.

蛍光性物質を高感度にかつ選択性良く分析する手段として、分光蛍光測定が広く行われている。これは、試料に単色光を照射することによって光学的に励起し、この励起された試料の発する蛍光を分光してスペクトルを得るものである。この分光蛍光測定には、通常、分光蛍光光度計が用いられる。この分光蛍光測定と分光蛍光光度計については、非特許文献１に詳しく解説されている。また、特許文献１には、光源位置の調整を自動化し、人手の介入を排除することで光源位置調整の容易化を図る技術が記載されている。
特開平０５−２６４３５１号公報 保田和雄、他著 「けい光分析」 講談社 １９７３年 As a means for analyzing a fluorescent substance with high sensitivity and good selectivity, spectrofluorescence measurement is widely performed.

分光蛍光光度計の光源としては紫外から可視にわたって強力な光が求められるために、キセノンランプが使われることが多い。キセノンランプは高圧のキセノンガス中に置かれた２つの針状電極の間の放電で発光するもので、点状のごく狭い領域で発光する。分光蛍光光度計では、光源のこの小さな発光点を正確に励起側分光器２の最適な位置（通常は入射スリット）に結像させることが求められる。発光点が、最適な位置からずれると、分光器に入る光量が減ってしまうため、測定感度が落ちてしまうことになるからである。キセノンランプにおいてはランプの劣化に伴って電極上で発光点が移動することがあり、その都度光源位置を最適位置に合わせることが必要になる。このため、分光蛍光光度計では光源を最適位置に合わせるための調整機構を持たせる方法がある。   A xenon lamp is often used as a light source for a spectrofluorometer because it requires strong light from ultraviolet to visible. A xenon lamp emits light by discharge between two needle-like electrodes placed in a high-pressure xenon gas, and emits light in a very narrow spot-like region. In a spectrofluorometer, it is required to accurately form an image of this small light emitting point of a light source at an optimum position (usually an entrance slit) of the excitation side spectroscope 2. This is because if the emission point deviates from the optimum position, the amount of light entering the spectroscope is reduced, resulting in a decrease in measurement sensitivity. In the xenon lamp, the light emitting point may move on the electrode as the lamp deteriorates, and it is necessary to adjust the light source position to the optimum position each time. For this reason, in the spectrofluorometer, there is a method of providing an adjustment mechanism for adjusting the light source to the optimum position.

また、従来の分光蛍光光度計用光源位置調整機構では、Ｘ，Ｙ，Ｚの３方向の調整を一方向から動かし集光効率の向上を図っているが、Ｘ方向は、Ｘ調整軸を軸方向にスライドさせ、ランプカバー押し板を押すことで、ランプカバーに取り付けたランプカバー軸を支点に、円弧の軌道になり、Ｚ方向は、Ｚ調整軸を軸方向にスライドさせ、ランプカバー支え金具を押すことで、Ｚ支点軸を支点に、ランプカバーに取り付けたランプカバー軸を、ランプカバー支え金具が円弧軌道で、ランプカバーが移動する。しかも、Ｘ方向とＺ方向の動きは、ランプカバーに取り付いたランプカバー軸を共用しているので、Ｘ方向とＺ方向の動きが多少だが連動して、Ｘ方向のみ調整をしても、Ｚ方向も一緒に移動し、Ｚ方向のみ調整をしても、Ｘ方向が一緒に移動するので、最適な位置に調整するのに時間がかかり困難であった。本来は、Ｘ，Ｙ，Ｚの３方向に直線的な動きが欲しいところを円弧の動きで代用したり、Ｘ，Ｙ，Ｚの３方向を独立した機構にする所を、共用していることから問題が生じている。   In addition, in the conventional light source position adjustment mechanism for a spectrofluorometer, the three-direction adjustment of X, Y, and Z is moved from one direction to improve the light collection efficiency. However, the X direction is based on the X adjustment axis. Slide in the direction and press the lamp cover push plate, the lamp cover shaft attached to the lamp cover becomes a circular track with the fulcrum as the fulcrum. In the Z direction, the Z adjustment shaft is slid in the axial direction, and the lamp cover support bracket By pressing, the lamp cover moves on the lamp cover shaft attached to the lamp cover with the Z fulcrum shaft as a fulcrum, and the lamp cover moves in an arc orbit. In addition, since the movement in the X direction and the Z direction share the lamp cover shaft attached to the lamp cover, the movement in the X direction and the Z direction are somewhat linked, and even if only the X direction is adjusted, the Z direction Even if only the Z direction is adjusted, the X direction is moved together even if only the Z direction is adjusted. Originally, a place where linear movement in the three directions of X, Y, and Z is desired can be substituted with a circular movement, or a place where the three directions of X, Y, and Z are made independent is shared. Is causing problems.

更に、キセノンランプの放出する光はレンズあるいは凹面ミラーで集光されて励起側分光器に導かれる。このとき、一般には光源の光が導かれる光軸と光源位置調整機構の調整軸とは向きが異なるので、光軸上で光源位置を調整しようとすると複数の調整軸での調整が必要になり、調整を困難にしている。特許文献１は、この従来技術の問題を回避するために、光源位置の調整を自動化し、人手の介入を排除することで光源位置調整の容易化を図ったものである。しかしながら、この方法では光源位置の駆動機構が必要であり、構造が大きくなる事や、コストアップになる欠点がある。   Furthermore, the light emitted from the xenon lamp is condensed by a lens or a concave mirror and guided to the excitation-side spectroscope. At this time, since the direction of the optical axis through which the light from the light source is guided and the adjustment axis of the light source position adjustment mechanism are generally different, adjustment with a plurality of adjustment axes is required to adjust the light source position on the optical axis. Making adjustments difficult. In order to avoid the problems of the prior art, Patent Document 1 automates the adjustment of the light source position and eliminates human intervention, thereby facilitating the adjustment of the light source position. However, this method requires a driving mechanism for the light source position, and has a drawback that the structure becomes large and the cost increases.

本発明は、光源の発光点を、最適位置に調整できる光源位置調整機構を提供することを目的とする。   An object of this invention is to provide the light source position adjustment mechanism which can adjust the light emission point of a light source to the optimal position.

本発明は、分光蛍光光度計の最適な位置に、光源の発光点が容易に合わせられるよう、Ｘ，Ｙ，Ｚの３方向の駆動を、直線的に独立して駆動出来る機構にし、その駆動機構を、一方向から駆動させ、位置合わせが出来るようにしたものである。   In the present invention, the driving in the three directions X, Y, and Z is linearly and independently driven so that the light emitting point of the light source can be easily adjusted to the optimum position of the spectrofluorometer. The mechanism is driven from one direction so that it can be aligned.

本発明によれば、簡単な操作で確実な光源の最適位置合わせが可能であり、また、少ない部品件数で微調整が可能であり、操作性が大幅に向上する。   According to the present invention, it is possible to reliably perform optimum alignment of a light source with a simple operation, and fine adjustment can be performed with a small number of parts, which greatly improves operability.

本発明の分光蛍光光度計は、装置内の構造上、一方向で、装置の外側から容易に光源の位置を、Ｘ，Ｙ，Ｚの３方向を直線的に独立して調整を出来るようにした。以下に、本発明の実施の形態について図面に基づいて説明する。
分光蛍光光度計は、通常、図７に示すように、光源位置調整機構３３から放射される光を分光して励起用単色光を得るための励起側分光器３４と励起側分光器の出射光を検知する励起側検知器３５、励起された光を試料３６に当て、その試料が発する蛍光を分離するめの蛍光側光度計３７と、この蛍光側分光器の出射光を検知する蛍光側検知器３８とで構成される。光源位置調整機構３３から放射される光はレンズあるいはミラーで集光されて励起側分光器３４に導かれ、励起側分光器３４で単色光になった光は試料３６を照射し、これを励起する。試料３６から放射された蛍光は蛍光側光度計３７に導かれ分光された後、検知器３８で検出される。
また、図８に示すように、分光蛍光光度計用光源位置調整機構では、Ｘ，Ｙ，Ｚの３方向の調整を一方向から動かし集光効率の向上を図っているが、Ｘ方向は、Ｘ調整軸４０を軸方向にスライドさせ、ランプカバー押し板４５を押すことで、ランプカバー４４に取り付けたランプカバー軸４６を支点に、円弧の軌道になり、Ｚ方向は、Ｚ調整軸４１を軸方向にスライドさせ、ランプカバー支え金具４７を押すことで、Ｚ支点軸を支点に、ランプカバー４４に取り付けたランプカバー軸４６を、ランプカバー支え金具４７が円弧軌道で、ランプカバー４４が移動する。しかも、Ｘ方向とＺ方向の動きは、ランプカバー４４に取り付いたランプカバー軸４６を共用しているので、Ｘ方向とＺ方向動きが多少だが連動して、Ｘ方向のみ調整をしても、Ｚ方向も一緒に移動し、Ｚ方向のみ調整をしても、Ｘ方向が一緒に移動している。 The spectrofluorometer according to the present invention can adjust the position of the light source in one direction from the outside of the apparatus and the three directions of X, Y, and Z linearly and independently in one direction due to the structure inside the apparatus. did. Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 7, the spectrofluorometer usually emits light from the excitation-side spectroscope 34 and the excitation-side spectroscope for separating the light emitted from the light source position adjusting mechanism 33 and obtaining monochromatic light for excitation. An excitation-side detector 35 for detecting the fluorescence, a fluorescence-side photometer 37 for separating the fluorescence emitted from the sample by applying the excited light to the sample 36, and a fluorescence-side detector for detecting the emitted light of the fluorescence-side spectrometer 38. The light emitted from the light source position adjusting mechanism 33 is condensed by a lens or a mirror and guided to the excitation-side spectroscope 34, and the light converted to monochromatic light by the excitation-side spectroscope 34 irradiates the sample 36 and excites it. To do. The fluorescence emitted from the sample 36 is guided to the fluorescence side photometer 37 and dispersed, and then detected by the detector 38.
Further, as shown in FIG. 8, the light source position adjusting mechanism for the spectrofluorophotometer moves the adjustment in the three directions X, Y, and Z from one direction to improve the light collection efficiency. When the X adjustment shaft 40 is slid in the axial direction and the lamp cover pressing plate 45 is pushed, an arc trajectory is formed with the lamp cover shaft 46 attached to the lamp cover 44 as a fulcrum, and the Z adjustment shaft 41 is moved in the Z direction. By sliding in the axial direction and pressing the lamp cover support bracket 47, the lamp cover support bracket 47 is moved in an arc path and the lamp cover 44 is moved around the lamp cover shaft 46 attached to the lamp cover 44 with the Z fulcrum shaft as a fulcrum. To do. In addition, since the movement in the X direction and the Z direction share the lamp cover shaft 46 attached to the lamp cover 44, the movement in the X direction and the Z direction are somewhat interlocked, and even if only the X direction is adjusted, The Z direction also moves together, and the X direction moves together even if only the Z direction is adjusted.

分光蛍光光度計は、図７に示すように、光源位置調整機構３３からの光を励起側分光器３４に照射し、励起側分光器３４で、光源位置調整機構３３からの光を単色光にして取り出し、励起光側検知器３５で励起側の出射光を検知し、試料３６に照射する。そして、試料３６から発する蛍光を蛍光側分光器３７で分離し、蛍光側分光器３７からの出射光を蛍光側検知器３８で検知するように構成されている。   As shown in FIG. 7, the spectrofluorometer irradiates light from the light source position adjustment mechanism 33 to the excitation side spectroscope 34, and the excitation side spectroscope 34 converts the light from the light source position adjustment mechanism 33 to monochromatic light. The excitation light side detector 35 detects the exit light on the excitation side and irradiates the sample 36. Then, the fluorescence emitted from the sample 36 is separated by the fluorescence side spectroscope 37, and the emitted light from the fluorescence side spectroscope 37 is detected by the fluorescence side detector 38.

本発明の実施例１では、その光源位置調整機構３３からの光を励起側分光器３４内に取り込む際、最適な位置に集光させることが出来るように、光源位置調整機構３３にＸ，Ｙ，Ｚの３方向を独立して直線的に、尚且つ一方向からの調整を可能とする機構を持たせた。   In the first embodiment of the present invention, when the light from the light source position adjusting mechanism 33 is taken into the excitation-side spectroscope 34, the light source position adjusting mechanism 33 has X and Y so that it can be condensed at an optimum position. , Z are independently linearly provided with a mechanism that allows adjustment from one direction.

光源位置調整機構３３は、消耗品であるキセノンランプ２を容易に交換が出来るようにキセノンランプ取り付け金具（止めねじ８，ランプホルダー７，ガイシ６，絶縁カバー５，−側電極４，＋側電極３で構成）に、キセノンランプ２をキセノンランプ取り付け金具の＋側電極と−側電極に固定し、そのキセノンランプ取り付け金具ごとキセノンランプ２をランプカバー９に取り付け、止めねじ８でランプカバー９に固定する。ランプカバー９にキセノンランプ取り付け金具を固定することで、キセノンランプ取り付け金具がランプカバー９と一体となり、Ｘ調整軸１５、Ｙ調整軸１９、Ｚ調整軸２５を使いＸ方向，Ｙ方向，Ｚ方向の調整機構を介して、ランプカバー９を動かすことにより、キセノンランプ取り付け金具に取り付けたキセノンランプ２の調整を行なう。   The light source position adjusting mechanism 33 is a xenon lamp mounting bracket (set screw 8, lamp holder 7, insulator 6, insulating cover 5, negative electrode 4, positive electrode, so that the xenon lamp 2 which is a consumable can be easily replaced. 3), the xenon lamp 2 is fixed to the + side electrode and the − side electrode of the xenon lamp mounting bracket, the xenon lamp 2 is mounted to the lamp cover 9 together with the xenon lamp mounting bracket, and the set screw 8 is attached to the lamp cover 9 Fix it. By fixing the xenon lamp mounting bracket to the lamp cover 9, the xenon lamp mounting bracket is integrated with the lamp cover 9, and the X, Y, and Z directions are used using the X adjustment shaft 15, the Y adjustment shaft 19, and the Z adjustment shaft 25. The xenon lamp 2 attached to the xenon lamp mounting bracket is adjusted by moving the lamp cover 9 via the adjusting mechanism.

キセノンランプ２を取り付けたキセノンランプ取り付け金具をランプカバー９に固定することで、キセノンランプ２を囲む形状となる。その形状のランプカバー９から光軸１０方向に光を取り出し、励起側分光器３４に照射する。光を効率良く励起側分光器３４の最適な位置に集光せる為に、Ｘ，Ｙ，Ｚ方向の調整を独立して出来る機構を用いると共に、一方向からの調整が出来る様になっている。   By fixing the xenon lamp mounting bracket to which the xenon lamp 2 is attached to the lamp cover 9, a shape surrounding the xenon lamp 2 is obtained. Light is extracted from the lamp cover 9 having the shape in the direction of the optical axis 10 and irradiated to the excitation-side spectroscope 34. In order to efficiently collect light at the optimum position of the excitation-side spectroscope 34, a mechanism that can independently adjust the X, Y, and Z directions is used, and adjustment from one direction is possible. .

Ｘ方向調整機構（図１，図４）は、Ｘ調整軸１５、Ｘベース１６、Ｘガイド軸１７、Ｘ方向保持ばね１８、Ｙベース２１から成る。Ｘベース１６を光源位置合わせ機構取り付けベース１４に取り付けねじ３２で固定する。Ｘベース１６には、Ｘ調整軸１５とＸガイド軸１７を通す穴が開いており、Ｙベース２１には、Ｘ調整軸１５とＸガイド軸１７を通す穴と、Ｘ調整軸１５を回転させることで、Ｘ方向軌道１１方向にＸ調整軸１５が移動するように、ねじ穴が開いており、Ｘ調整軸１５は、一方の軸端末がねじ形状になっている。   The X direction adjusting mechanism (FIGS. 1 and 4) includes an X adjusting shaft 15, an X base 16, an X guide shaft 17, an X direction holding spring 18, and a Y base 21. The X base 16 is fixed to the light source alignment mechanism mounting base 14 with mounting screws 32. The X base 16 has a hole through which the X adjustment shaft 15 and the X guide shaft 17 pass. The Y base 21 has a hole through which the X adjustment shaft 15 and the X guide shaft 17 pass and the X adjustment shaft 15 is rotated. Thus, a screw hole is opened so that the X adjustment shaft 15 moves in the direction of the X direction trajectory 11, and one end of the X adjustment shaft 15 has a screw shape.

光源位置合わせ機構取り付けベース１４に固定されたＸベース１６とＹベース２１をＸ調整軸１５とＸガイド軸１７で組み付け、Ｘガイド軸１７にＸベース１６とＹベース２１の間の所でＸ方向保持ばね１８を組み付ける。Ｘガイド軸１７が抜けないように、Ｅ型止め輪３１を組み付ける。Ｘ調整軸１５は、光源位置合わせ機構取り付けベース１４に固定されたＸベース１６にＥ型止め輪３１で固定することにより、Ｘ調整軸１５を回転させることで、Ｘ調整軸１５と、Ｙベース２１のねじ形状により、Ｘ方向軌道１１方向に、Ｙベース２１が移動する。Ｘ方向軌道１１の移動範囲を、Ｅ型止め輪３１を組み付けることで規制している。Ｘ調整機構には、Ｘ方向保持ばね１８の力で一方向に力を加えることにより、ねじ構造による移動機構のがたを無くしている。   The X base 16 and the Y base 21 fixed to the light source alignment mechanism mounting base 14 are assembled by the X adjustment shaft 15 and the X guide shaft 17, and the X guide shaft 17 is located in the X direction between the X base 16 and the Y base 21. The holding spring 18 is assembled. The E-type retaining ring 31 is assembled so that the X guide shaft 17 does not come off. The X adjustment shaft 15 is fixed to the X base 16 fixed to the light source alignment mechanism mounting base 14 with the E-type retaining ring 31, and the X adjustment shaft 15 is rotated to thereby rotate the X adjustment shaft 15 and the Y base. The Y base 21 moves in the X-direction trajectory 11 direction due to the screw shape of 21. The movement range of the X-direction track 11 is regulated by assembling the E-type retaining ring 31. By applying a force in one direction to the X adjustment mechanism with the force of the X-direction holding spring 18, the movement mechanism due to the screw structure is eliminated.

Ｙ方向調整機構（図１，図３）は、Ｙ調整軸１９、Ｙカム２０、Ｙベース２１、Ｙカム受け２２、Ｙガイド軸２３、Ｙ方向保持ばね２４、Ｚベース２８、Ｚガイド軸２９から成る。Ｘ方向調整機構（図１，図４）に組み付けられたＹベース２１には、Ｙ調整軸１９を通す穴とＹ調整軸１９を回転させることで、Ｘ方向軌道１１方向にＹ調整軸１９が移動するように、ねじ穴が開いており、Ｙ調整軸１９は、一方の軸端末がねじ形状になっている。ランプガイド９に固定されているＹカム受け２２とＺベース２８には、Ｚガイド軸２９を通す穴が開いており、Ｙカム受け２２にＺガイド軸２９にてＺベース２８を組み付ける。また、Ｘ方向調整機構（図１，図４）に組み付いたＹベース２１とＺベース２８には、Ｙガイド軸２３を通す穴が開いており、Ｙガイド軸２３でＹベース２１とＺベース２８を組み付け、Ｙガイド軸２３にＹベース２１とＺベース２８の間の所でＹ方向保持ばね２４を組み付ける。Ｙガイド軸２３が抜けないように、Ｅ型止め輪３１を組み付ける。Ｙ調整軸１９には、Ｙカム２０をＥ型止め輪３１で固定し、ランプカバー９に固定されているＹカム受け２２と組み合わせる。Ｙ調整軸１９を回転させることで、Ｙ調整軸１９と、Ｙベース２１のねじ形状により、Ｙ調整軸１９方向に、Ｙカム２０が移動する。Ｙカム２０が移動することで、Ｙカム受け２２の傾斜部に当たり、Ｙガイド軸２３にそって、Ｙ方向起動１２方向にランプカバー９が移動する。Ｙ方向軌道１２の移動範囲を、Ｅ型止め輪３１を組み付けることで規制している。Ｙ調整機構には、Ｙ方向保持ばね２４の力で一方向に力を加えることにより、ねじ構造による移動機構のがたを無くしている。   The Y direction adjusting mechanism (FIGS. 1 and 3) includes a Y adjusting shaft 19, a Y cam 20, a Y base 21, a Y cam receiver 22, a Y guide shaft 23, a Y direction holding spring 24, a Z base 28, and a Z guide shaft 29. Consists of. In the Y base 21 assembled in the X direction adjusting mechanism (FIGS. 1 and 4), the Y adjusting shaft 19 is rotated in the direction of the X direction trajectory 11 by rotating the hole through which the Y adjusting shaft 19 passes and the Y adjusting shaft 19. The screw hole is opened so that it may move, and one end of the Y adjustment shaft 19 has a screw shape. The Y cam receiver 22 and the Z base 28 fixed to the lamp guide 9 have a hole through which the Z guide shaft 29 is passed, and the Z base 28 is assembled to the Y cam receiver 22 by the Z guide shaft 29.

A Y cam 20 is fixed to the Y adjustment shaft 19 with an E-type retaining ring 31 and combined with a Y cam receiver 22 fixed to the lamp cover 9. By rotating the Y adjustment shaft 19, the Y cam 20 moves in the direction of the Y adjustment shaft 19 due to the thread shape of the Y adjustment shaft 19 and the Y base 21. As the Y cam 20 moves, the lamp cover 9 moves in the Y direction activation 12 direction along the Y guide shaft 23 by hitting the inclined portion of the Y cam receiver 22. The movement range of the Y-direction track 12 is restricted by assembling the E-type retaining ring 31. By applying a force in one direction to the Y adjustment mechanism with the force of the Y-direction holding spring 24, the movement mechanism due to the screw structure is eliminated.

Ｚ方向調整機構（図１，図２）は、Ｙベース２１、Ｙカム受け２２、Ｚ調整軸２５、Ｚカム２６、Ｚカム受け２７、Ｚベース２８、Ｚガイド軸２９、Ｚ方向保持ばね３０から成る。Ｘ方向調整機構（図１，図４）に組み付けられたＹベース２１には、Ｚ調整軸２５とＺガイド軸２０を通す穴が開いており、Ｚ調整軸２５を回転させることで、Ｘ方向軌道１１方向にＺ調整軸２５が移動するように、ねじ穴が開いており、Ｚ調整軸２５は、一方の軸端末がねじ形状になっている。Ｙ方向調整機構（図１，図３）で組み付けたＺベース２８は、Ｚガイド軸２９で組み付け、Ｚガイド軸２９にＺベース２８とランプカバー９に」固定されているＹカム受け２２の間の所でＺ方向保持ばね２４を組み付ける。Ｚガイド軸２９が抜けないように、Ｅ型止め輪３１を組み付ける。Ｚ調整軸２５には、Ｚカム２６をＥ型止め輪３１で固定し、ランプカバー９に固定されているＺカム受け２７と合わせる。Ｚ調整軸２５を回転させることで、Ｚ調整軸２５と、Ｙベース２１のねじ形状により、Ｘ方向軌道１１方向に、Ｚカム２６が移動する。Ｚカム２６が移動することで、ランプカバー９に固定されているＹカム受け２２に取り付けた、Ｚカム受け２７にＺカム２６の傾斜部を当てることにより、Ｚガイド軸２９にそって、Ｚ方向起動１３方向にランプカバー９が移動する。Ｚ方向軌道１３の移動範囲を、Ｅ型止め輪３１を組み付けることで規制している。Ｚ調整機構には、Ｚ方向保持ばね３０の力で一方向に力を加えることにより、ねじ構造による移動機構のがたを無くしている。   The Z direction adjustment mechanism (FIGS. 1 and 2) includes a Y base 21, a Y cam receiver 22, a Z adjustment shaft 25, a Z cam 26, a Z cam receiver 27, a Z base 28, a Z guide shaft 29, and a Z direction holding spring 30. Consists of. The Y base 21 assembled in the X direction adjustment mechanism (FIGS. 1 and 4) has a hole through which the Z adjustment shaft 25 and the Z guide shaft 20 are passed. By rotating the Z adjustment shaft 25, the X direction A screw hole is opened so that the Z adjustment shaft 25 moves in the direction of the track 11, and one end of the Z adjustment shaft 25 has a screw shape. The Z base 28 assembled by the Y-direction adjusting mechanism (FIGS. 1 and 3) is assembled by the Z guide shaft 29 and between the Y cam receiver 22 fixed to the Z guide shaft 29 and the Z base 28 and the lamp cover 9. At this point, the Z-direction holding spring 24 is assembled. The E-type retaining ring 31 is assembled so that the Z guide shaft 29 does not come off. A Z cam 26 is fixed to the Z adjustment shaft 25 with an E-type retaining ring 31 and is aligned with a Z cam receiver 27 fixed to the lamp cover 9. By rotating the Z adjustment shaft 25, the Z cam 26 moves in the X-direction trajectory 11 direction due to the Z adjustment shaft 25 and the thread shape of the Y base 21. By moving the Z cam 26, the inclined portion of the Z cam 26 is applied to the Z cam receiver 27 attached to the Y cam receiver 22 fixed to the lamp cover 9. The lamp cover 9 moves in the direction starting direction 13. The movement range of the Z-direction track 13 is regulated by assembling the E-type retaining ring 31. By applying a force in one direction to the Z adjustment mechanism with the force of the Z-direction holding spring 30, the movement mechanism due to the screw structure is eliminated.

Ｘ方向の調整は、Ｘ調整軸１５により調整を行う。Ｙベース２１とＸ調整軸１５を、ねじ形状にして組み付ける事で、Ｘ調整軸１５を回転させると、Ｙベース２１を基準に、Ｘ調整軸１５が、Ｘ方向軌道１１方向に移動する。光源位置合わせ機構３３の構造は、光源位置合わせ機構取り付けベース１４に取り付けたＸベース１６にＸ調整軸１５を固定する機構なので、Ｘ調整軸１５を回転させると、Ｙベース２１がＸ方向軌道１１方向に移動する。Ｙベース２１を動かすことにより、Ｙガイド軸２３でＹベース２１とＺベース２８が組み付いており、Ｚガイド軸で、Ｚベース２８とランプカバー９に固定されているＹカム受け２２に組み付けられているので、Ｘ調整軸１５を動かすと、ランプカバー９を動かす事になり、キセノンランプ２は、ランプカバー９に組み付けられているので、最終的に、キセノンランプ２がＸ方向軌道１１方向に動く機構になっている。   The adjustment in the X direction is performed by the X adjustment shaft 15. When the X adjustment shaft 15 is rotated by assembling the Y base 21 and the X adjustment shaft 15 in a screw shape, the X adjustment shaft 15 moves in the X direction trajectory 11 direction with respect to the Y base 21. Since the structure of the light source alignment mechanism 33 is a mechanism for fixing the X adjustment shaft 15 to the X base 16 attached to the light source alignment mechanism attachment base 14, when the X adjustment shaft 15 is rotated, the Y base 21 is moved to the X direction track 11. Move in the direction. By moving the Y base 21, the Y base 21 and the Z base 28 are assembled by the Y guide shaft 23, and the Z guide shaft is assembled to the Y cam receiver 22 fixed to the Z base 28 and the lamp cover 9. Therefore, when the X adjustment shaft 15 is moved, the lamp cover 9 is moved. Since the xenon lamp 2 is assembled to the lamp cover 9, the xenon lamp 2 is finally moved in the X-direction trajectory 11 direction. It is a moving mechanism.

Ｙ方向の調整は、Ｙ調整軸１９により調整を行う。Ｙベース２１とＹ調整軸１９を、ねじ形状にして組み付ける事で、Ｙ調整軸１９を回転させると、Ｙベース２１を基準に、Ｙ調整軸１９が、Ｘ方向軌道１１方向に移動する。そのＹ調整軸１９に、Ｙカム２０を組み付け、Ｙ調整軸１９を動かす事により、Ｙカム２０もいっしょに、Ｘ方向軌道１１方向に動く。そのＹカム２０を、ランプカバー９に固定してあるＹカム受け２２の傾斜部に押し当てて、Ｙ調整軸１９を動かすことで、Ｙカム２０がいっしょに動き、Ｙカム２０が、Ｙカム受け２２の傾斜に沿って動く。ランプカバー９に固定してあるＹカム受け２２は、Ｚガイド軸で、Ｚベース２８と組み付いており、Ｚベース２８とＹベース２１は、Ｙガイド軸２３と組み付いているので、Ｙ調整軸１９の動きによって、いっしょに動く、Ｙカム２０により、Ｙカム受け２２が押されると、Ｙガイド軸２３により、Ｙ方向軌道１２方向に移動する。Ｙカム受け２２が動くことで、ランプカバー９も動き、ランプカバー９に組み付けられたキセノンランプ２も、Ｙ方向軌道１２方向に動く機構になっている。   Adjustment in the Y direction is performed by the Y adjustment shaft 19. When the Y adjustment shaft 19 is rotated by assembling the Y base 21 and the Y adjustment shaft 19 in a screw shape, the Y adjustment shaft 19 moves in the X direction trajectory 11 direction with respect to the Y base 21. By attaching the Y cam 20 to the Y adjustment shaft 19 and moving the Y adjustment shaft 19, the Y cam 20 also moves in the X-direction trajectory 11 direction together. The Y cam 20 is pressed against the inclined portion of the Y cam receiver 22 fixed to the lamp cover 9 and the Y adjusting shaft 19 is moved, so that the Y cam 20 moves together, and the Y cam 20 moves to the Y cam. It moves along the inclination of the receiver 22. The Y cam receiver 22 fixed to the lamp cover 9 is a Z guide shaft and is assembled with the Z base 28, and the Z base 28 and the Y base 21 are assembled with the Y guide shaft 23. When the Y cam receiver 22 is pushed by the Y cam 20 that moves together by the movement of the shaft 19, the Y guide shaft 23 moves in the Y direction trajectory 12 direction. When the Y cam receiver 22 moves, the lamp cover 9 also moves, and the xenon lamp 2 assembled to the lamp cover 9 also moves in the Y direction track 12 direction.

Ｚ方向の調整は、Ｚ調整軸２５により調整を行う。Ｙベース２１とＺ調整軸２５を、ねじ形状にして組み付ける事で、Ｚ調整軸２５を回転させると、Ｙベース２１を基準に、Ｚ調整軸２５が、Ｘ方向軌道１１方向に移動する。そのＺ調整軸２５に、Ｚカム２６を組み付け、Ｚ調整軸２５を動かす事により、Ｚカム２６もいっしょに、Ｘ方向軌道１１方向に動く。そのＺカム２６を、ランプカバー９にＹカム受け２２介して固定してあるＺカム受け２７に、Ｚカム２６の傾斜部を押し当てて、Ｚ調整軸２５を動かすことで、Ｚカム２６がいっしょに動き、Ｚカム２６の傾斜部に沿って、Ｚカム受け２７を動かす。ランプカバー９に固定してあるＹカム受け２２は、Ｚガイド軸で、Ｚベース２８と組み付いているので、Ｚ調整軸２５の動きによっていっしょに動く、Ｚカム２６により、Ｚカム受け２７が押されると、Ｚガイド軸２９により、Ｚ方向軌道１３方向に移動する。Ｚカム受け２７が動くことで、ランプカバー９も動き、ランプカバー９に組み付けられたキセノンランプ２も、Ｚ方向軌道１２方向に動く機構になっている。   Adjustment in the Z direction is performed by the Z adjustment shaft 25. When the Z adjustment shaft 25 is rotated by assembling the Y base 21 and the Z adjustment shaft 25 into a screw shape, the Z adjustment shaft 25 moves in the X direction trajectory 11 direction with respect to the Y base 21. By attaching the Z cam 26 to the Z adjustment shaft 25 and moving the Z adjustment shaft 25, the Z cam 26 also moves in the X-direction trajectory 11 direction together. By moving the Z adjustment shaft 25 by pressing the inclined portion of the Z cam 26 against the Z cam receiver 27 fixed to the lamp cover 9 via the Y cam receiver 22, the Z cam 26 is The Z cam receiver 27 is moved along the inclined portion of the Z cam 26. The Y cam receiver 22 fixed to the lamp cover 9 is a Z guide shaft and is assembled with the Z base 28. Therefore, the Z cam 26 moves together with the movement of the Z adjustment shaft 25. When pushed, the Z guide shaft 29 moves in the Z direction orbit 13 direction. When the Z cam receiver 27 moves, the lamp cover 9 also moves, and the xenon lamp 2 assembled to the lamp cover 9 also moves in the Z direction track 12 direction.

Ｘ調整機構は、ねじの送りそのものの動きをそのままＸ方向軌道１１方向に得ることが可能だが、Ｙ調整機構とＺ調整機構は、Ｘ調整機構と同じ前後の動きを、斜めの構造の部品を動かしたい部品を当てて、動かしたい部品を、動かしたい方向にガイド軸を用いて組み付けることにより、同一方向から任意の方向に物を動かす機構が出来る。   The X adjustment mechanism can obtain the movement of the screw feed itself in the X direction trajectory 11 as it is. However, the Y adjustment mechanism and the Z adjustment mechanism can move the same longitudinal movement as the X adjustment mechanism, with the parts of the diagonal structure. By applying the part to be moved and assembling the part to be moved using the guide shaft in the direction to be moved, a mechanism for moving an object from the same direction to an arbitrary direction can be formed.

本実施例１によれば、Ｘ、Ｙ、Ｚ方向の調整が独立して可能なため正確な位置合わせが可能である。本実施例１によれば、Ｙ方向の位置合わせ及び、Ｚ方向の位置合わせにカム（Ｙカム２０，Ｚカム２６）を使用することで、簡単な構造で、Ｘ、Ｙ、Ｚの３方向を独立して調整出来る。また、Ｙ方向とＺ方向の回転軸にカムを連結させることで、一方向から調整が可能になり、機構部の小型化も可能になる。本実施例１のＸ調整軸１５、Ｙ調整軸１９、Ｚ調整軸２５と、Ｙベース２１のねじのピッチを細かくすることで、微細な位置調整も可能になる。本実施例１のＸ調整軸１５、Ｙ調整軸１９、Ｚ調整軸２５は、ドライバーで、調整軸を回して、位置調整する構造になっているが、Ｘ調整軸１５、Ｙ調整軸１９、Ｚ調整軸２５の先端部を、ドライバーで回転させる形状でなく、つまみ形状にすることで、ドライバーを使用せず、光源の位置調整が可能になり、さらに操作性が向上する。   According to the first embodiment, since the X, Y, and Z directions can be adjusted independently, accurate alignment is possible. According to the first embodiment, the cams (Y cam 20 and Z cam 26) are used for Y-direction alignment and Z-direction alignment, so that the three directions X, Y, and Z can be achieved with a simple structure. Can be adjusted independently. Further, by connecting the cam to the rotation shafts in the Y direction and the Z direction, adjustment can be performed from one direction, and the mechanism portion can be downsized. By making the pitch of the screws of the X adjustment shaft 15, the Y adjustment shaft 19, the Z adjustment shaft 25 and the Y base 21 of the first embodiment fine, fine position adjustment is also possible. The X adjustment shaft 15, Y adjustment shaft 19, and Z adjustment shaft 25 of the first embodiment are structured to adjust the position by turning the adjustment shaft with a screwdriver, but the X adjustment shaft 15, the Y adjustment shaft 19, By making the tip of the Z adjustment shaft 25 a knob shape instead of a shape rotated by a screwdriver, the position of the light source can be adjusted without using a screwdriver, and the operability is further improved.
