Description

本発明は、曲面ミラーの調整装置に関する。   The present invention relates to an apparatus for adjusting a curved mirror.

以前より、画像調整素子からの画像光を屈折光学素子から構成される結像光学系へ入射し、結像光学系から出射した光線を曲面ミラーの反射面で反射することにより被投射面へ画像光を拡大投射する投射光学系は公知であった。このような構成の広角投射光学系では曲面ミラーの反射面の位置及び角度が被投射面に投影される投影画像の品質に大きく影響する。そのため、曲面ミラーの角度及び位置の調整機構が強く要望されていた。
例えば、曲面ミラーの反射面外の外周面や背面を曲面ミラーの保持部材により調整可能に三点支持をするフローティング機構などがある（特許文献１参照）。このフローティング機構では曲面ミラーを支持する三点の各点を独立して調整することにより、反射面の傾きを微調整可能になっている。 From the past, image light from the image adjusting element is incident on the imaging optical system composed of refractive optical elements, and the light emitted from the imaging optical system is reflected by the reflecting surface of the curved mirror to form an image on the projection surface. Projection optical systems for enlarging and projecting light have been known. In the wide-angle projection optical system having such a configuration, the position and angle of the reflecting surface of the curved mirror greatly affects the quality of the projected image projected on the projection surface. Therefore, a mechanism for adjusting the angle and position of the curved mirror has been strongly demanded.
For example, there is a floating mechanism that supports a three-point support so that the outer peripheral surface and the back surface of the curved mirror outside the reflecting surface can be adjusted by a holding member of the curved mirror (see Patent Document 1). In this floating mechanism, the inclination of the reflecting surface can be finely adjusted by independently adjusting the three points that support the curved mirror.

また、別の機構として、曲面ミラーを第１保持部材で保持し、第１保持部材を第２保持部材で保持を行い、第１保持部材に対して曲面ミラーを光軸と直交する第１軸を回動軸にして回動させ、第２保持部材に対して第１保持部材を光軸及び第１軸と直交する第２軸を回動軸にして回動させることにより、曲面ミラーの角度を微調整する機構がある（特許文献２参照）。この機構の構成では、各回動軸による角度調整を独自に調整可能であり、曲面ミラーの角度調整をフローティング機構と比べて容易に行うことが可能となる。   As another mechanism, the curved mirror is held by the first holding member, the first holding member is held by the second holding member, and the curved mirror is perpendicular to the optical axis with respect to the first holding member. By rotating the first holding member with respect to the second holding member about the optical axis and the second axis orthogonal to the first axis as the rotation axis. There is a mechanism for finely adjusting (see Patent Document 2). With this configuration of the mechanism, the angle adjustment by each rotation axis can be independently adjusted, and the angle adjustment of the curved mirror can be easily performed as compared with the floating mechanism.

しかし、特許文献１のフローティング機構の場合、三点のうち一点を調整すると、結果的に残りの二点により調整した曲面ミラーの姿勢に影響を与えてしまうため、精密な調整を行うには各点を何度も調製し直すことが必要である。また、フローティング支持では反射面の角度の調整のみしかできず、反射面の平行移動ができないため、完全に調整し切れない場合があった。   However, in the case of the floating mechanism of Patent Document 1, adjusting one of the three points results in an influence on the posture of the curved mirror adjusted by the remaining two points. It is necessary to re-prepare the points many times. In addition, with floating support, only the angle of the reflecting surface can be adjusted, and the reflecting surface cannot be moved in parallel.

また、特許文献２の構成では、曲面ミラーの角度の調整（チルト調整）はできるが、結像光学系に対する曲面ミラーの位置（シフト調整）の調整が行えないため、角度ではなく位置のずれによる光学性能の劣化を補正することができなかった。   In the configuration of Patent Document 2, the angle of the curved mirror (tilt adjustment) can be adjusted, but the position of the curved mirror (shift adjustment) with respect to the imaging optical system cannot be adjusted. The optical performance degradation could not be corrected.

本発明の課題は、曲面ミラーの調整装置において、反射面の角度及び位置をそれぞれ独自に調整可能として、より高精度の調整を可能とすることである。   An object of the present invention is to enable adjustment with higher accuracy by making it possible to independently adjust the angle and position of a reflecting surface in a curved mirror adjustment device.

「前提」
始めに、画像調整素子からの画像光を屈折光学素子から構成される結像光学系へ入射し、結像光学系から出射した光線を曲面ミラー１の反射面で反射することにより被投射面へ画像光を拡大投射する投射光学系において、図１に示すように、結像光学系の光線をＺ軸、画像調整素子の画像中心から出射した光線の軌跡の存在する平面内におけるＺ軸と直交する軸をＹ軸、Ｚ軸及びＹ軸とそれぞれ直交する軸をＸ軸と規定し、各軸と平行な方向をそれぞれＺ軸方向、Ｙ軸方向、Ｘ軸方向と規定する。 "Assumptions"
First, image light from the image adjusting element is incident on an image forming optical system composed of refractive optical elements, and a light beam emitted from the image forming optical system is reflected by the reflecting surface of the curved mirror 1 to the projection surface. In the projection optical system for enlarging and projecting image light, as shown in FIG. 1, the light beam of the imaging optical system is orthogonal to the Z axis and the Z axis in the plane where the locus of the light beam emitted from the image center of the image adjustment element exists. The axis to be defined is defined as the Y axis, the axis orthogonal to the Z axis and the Y axis is defined as the X axis, and the directions parallel to the respective axes are defined as the Z axis direction, the Y axis direction, and the X axis direction, respectively.

また、投射光学系を光軸が地面と平行となるように地面に設置した場合において、Ｚ軸方向において、画像調整素子側を前側、被投射面側を後側と規定し、Ｘ軸方向において、前側から後側を見た場合の左右をそれぞれ左側、右側と規定して、Ｙ軸方向において、前側から後側を見た場合の上下をそれぞれ上側、下側と規定し、左右方向はＸ軸方向、上下方向はＹ軸方向、前後方向はＺ軸方向とそれぞれ対応する。   When the projection optical system is installed on the ground so that the optical axis is parallel to the ground, the image adjustment element side is defined as the front side and the projection surface side is defined as the rear side in the Z-axis direction. When the front side is viewed from the rear side, the left and right sides are defined as the left side and the right side, respectively. In the Y-axis direction, the top and bottom when the rear side is viewed from the front side are defined as the upper side and the lower side, respectively. The axial direction and the vertical direction correspond to the Y-axis direction, and the front-rear direction corresponds to the Z-axis direction.

曲面ミラー１は、非円形の曲線を回転軸にＺ軸を用いて回転させた際に形成される非球面のうち、鏡軸であるＺ軸上の面を含まない一部の面を用いた形状を有しており、結像光学系の光軸及び曲面ミラー１の鏡軸は共軸である。   The curved mirror 1 uses a part of an aspheric surface formed by rotating a non-circular curve with the Z axis as a rotation axis and does not include a surface on the Z axis that is a mirror axis. The optical axis of the imaging optical system and the mirror axis of the curved mirror 1 are coaxial.

「曲面ミラー」
図１及び図２に示すように、曲面ミラー１の反射面外の外周面のＸ軸と平行な第１軸線上に、左右一箇所ずつ溝状の第１係合部１ａが形成されている。この第１係合部１ａは、曲面ミラー１の前側から後側へ向かって溝が形成され、反射面側は開放されている。 "Curved mirror"
As shown in FIG. 1 and FIG. 2, groove-shaped first engaging portions 1 a are formed on the first axis parallel to the X axis on the outer peripheral surface outside the reflecting surface of the curved mirror 1, one on each side. . In the first engagement portion 1a, a groove is formed from the front side to the rear side of the curved mirror 1, and the reflection surface side is open.

曲面ミラー１の下端部側には、軸心がＹ軸方向に向き、かつＺ軸と直交する突起部１ｂが形成されている。この突起部１ｂは、前後方向に貫通した穴部１ｃを有している。
また、曲面ミラー１の上端部側には、軸心がＹ軸方向に向い、かつＺ軸と直交する突起部１ｄが形成されている。 On the lower end side of the curved mirror 1, a projection 1b whose axis is oriented in the Y-axis direction and orthogonal to the Z-axis is formed. The protrusion 1b has a hole 1c penetrating in the front-rear direction.
Further, on the upper end portion side of the curved mirror 1, a projection 1d whose axis is directed in the Y-axis direction and orthogonal to the Z-axis is formed.

「第１保持部材」
曲面ミラー１の外周側には、図１及び図２に示すように、第１保持部材１１が配置されている。この第１保持部材１１は、内周側に曲面ミラー１を保持可能に形成されている。
第１保持部材１１には、曲面ミラー１の第１係合部１ａに対応する位置に、左右方向に貫通した貫通孔１１ａが形成されている。この左右の貫通孔１１ａには、軸心が各々Ｘ軸と平行な第１軸線上にある軸状部材の第１被係合部材２がそれぞれ嵌め込まれている。第１係合部１ａは第１被係合部材２と係合することにより、第１保持部材１１に第１軸線を回動軸として回動可能に保持されている。 "First holding member"
As shown in FIGS. 1 and 2, a first holding member 11 is disposed on the outer peripheral side of the curved mirror 1. The first holding member 11 is formed to hold the curved mirror 1 on the inner peripheral side.
The first holding member 11 is formed with a through hole 11a penetrating in the left-right direction at a position corresponding to the first engaging portion 1a of the curved mirror 1. In the left and right through-holes 11a, first engaged members 2 of shaft-like members each having an axial center on a first axis parallel to the X axis are fitted. The first engaging portion 1a is held by the first holding member 11 so as to be rotatable about the first axis as a rotation axis by engaging with the first engaged member 2.

また、一方の第１被係合部材２と第１保持部材１１との間にはスプリングワッシャ３が挿入されている。このスプリングワッシャ３により曲面ミラー１は一方の第１被係合部材２と共に第１保持部材１１の他方に押し付けられている。
第１保持部材１１には、曲面ミラー１の突起部１ｂに対応する位置に突起部１１ｂが形成されている。この突起部１１ｂには、前後方向に貫通しかつ前側の開口が狭くねじ穴状である座ぐり形状の穴部１１ｃが形成されている。そして、曲面ミラー１の穴部１ｃと第１保持部材１１の穴部１１ｃには、後側から調整用ねじ４が挿入されて、穴部１１ｃのねじ穴部と螺合している。また、穴部１１ｃの内部には、圧縮バネ５が後側から挿入されている。 A spring washer 3 is inserted between the first engaged member 2 and the first holding member 11. The curved washer 1 is pressed against the other of the first holding members 11 together with the first engaged member 2 by the spring washer 3.
On the first holding member 11, a protrusion 11 b is formed at a position corresponding to the protrusion 1 b of the curved mirror 1. The projection 11b is formed with a counterbore-shaped hole 11c that penetrates in the front-rear direction and has a narrow opening on the front side and has a screw hole shape. An adjustment screw 4 is inserted into the hole 1c of the curved mirror 1 and the hole 11c of the first holding member 11 from the rear side, and is screwed into the screw hole of the hole 11c. A compression spring 5 is inserted into the hole 11c from the rear side.

そして、第１保持部材１１には、曲面ミラー１の突起部１ｄに対応する位置に、位置調整用溝部１１ｄが形成されている。この位置調整用溝部１１ｄは、左右方向の溝幅が突起部１ｄの直径よりも大きく、前後方向の溝の深さが突起部１ｄの直径とほぼ等しくなっている。そして、第１保持部材１１の後側から突起部１ｄを位置調整用溝部１１ｄへ挿入した後、位置調整用溝部１１ｄの後側からビス６で固定される板バネ７により、突起部１ｄを位置調整用溝部１１ｄの底部である前側の壁面へ押し付けている。   In the first holding member 11, a position adjusting groove 11 d is formed at a position corresponding to the protrusion 1 d of the curved mirror 1. The position adjusting groove 11d has a groove width in the left-right direction larger than the diameter of the protrusion 1d, and the depth of the groove in the front-rear direction is substantially equal to the diameter of the protrusion 1d. Then, after the protrusion 1d is inserted into the position adjusting groove 11d from the rear side of the first holding member 11, the protrusion 1d is positioned by the leaf spring 7 fixed with the screw 6 from the rear side of the position adjusting groove 11d. It is pressed against the front wall surface which is the bottom of the adjusting groove 11d.

第１保持部材１１の上端部には、左右方向に離間した位置に二つの板バネ８の一端がビス９でそれぞれ固定されている。この板バネ８の他端は、第１保持部材１１の前側端部から前側へ突き出しており、第１保持部材１１内部の曲面ミラー１の外周部の上端部を付勢している。   At the upper end of the first holding member 11, one end of two leaf springs 8 is fixed with screws 9 at positions separated in the left-right direction. The other end of the leaf spring 8 projects forward from the front end portion of the first holding member 11 and biases the upper end portion of the outer peripheral portion of the curved mirror 1 inside the first holding member 11.

よって、図８及び図９に示すように、曲面ミラー１を第１保持部材１１に対して第１被係合部材２を介して保持した状態で調整ねじ４を調整することにより、曲面ミラー１を第１保持部材１１に対して第１軸線（Ｘ）を回転軸として回動可能とした第１角度調整機構Ａ１を構成している。この第１角度調整機構Ａ１により、曲面ミラー１の反射面の角度調整及び固定が可能となっている。   Therefore, as shown in FIGS. 8 and 9, the curved mirror 1 is adjusted by adjusting the adjustment screw 4 while holding the curved mirror 1 with respect to the first holding member 11 via the first engaged member 2. The first angle adjusting mechanism A1 is configured to be rotatable with respect to the first holding member 11 about the first axis (X) as a rotation axis. By this first angle adjustment mechanism A1, the angle adjustment and fixing of the reflection surface of the curved mirror 1 are possible.

また、スプリングワッシャ３によりＸ軸方向のガタツキを抑制し、板バネ７により曲面ミラー１の第１被係合部材２からの脱落及びＺ軸方向のガタツキを抑制し、板バネ８によりＹ軸方向のガタツキを抑制した第１姿勢保持機構Ｂ１を構成している。   Further, the spring washer 3 suppresses backlash in the X-axis direction, the leaf spring 7 suppresses the fall of the curved mirror 1 from the first engaged member 2 and backlash in the Z-axis direction, and the leaf spring 8 suppresses the backlash in the Y-axis direction. 1st attitude | position holding mechanism B1 which suppressed this rattling is comprised.

さらに、第１保持部材１１の左右方向の外周側の両側面には、延設部１１ｅが一つずつ形成されている。この延設部１１ｅには、上下方向に貫通し、左右方向に比べて前後方向に口径が大きくなった長穴状の穴部１１ｆが形成されている。
そして、２つの延設部１１ｅの後端部には、下方向に延設された延設部１１ｇがそれぞれ一つずつ形成されている。この延設部１１ｇには、Ｚ軸方向に貫通した穴部１１ｈが形成されている。 Furthermore, one extending portion 11e is formed on each side surface of the first holding member 11 on the outer peripheral side in the left-right direction. The extended portion 11e is formed with an elongated hole portion 11f that penetrates in the vertical direction and has a larger diameter in the front-rear direction than in the left-right direction.
One extending portion 11g extending downward is formed at each rear end of the two extending portions 11e. The extending portion 11g is formed with a hole portion 11h penetrating in the Z-axis direction.

また、第１保持部材１１の上端部には、調整用穴部１１ｉが形成されている。この調整用穴部１１ｉの中心軸は、Ｚ軸と直交するＹ軸方向にあり、中心軸とＺ軸の交点は曲面ミラー１の前側の表面付近で結ばれている。   An adjustment hole 11 i is formed at the upper end of the first holding member 11. The central axis of the adjustment hole portion 11i is in the Y-axis direction orthogonal to the Z-axis, and the intersection of the central axis and the Z-axis is connected near the front surface of the curved mirror 1.

「第２保持部材」
第１保持部材１１の背面側には、図３に示すように、第２保持部材１２が配置されている。この第２保持部材１２は、内周側に曲面ミラー１を保持した第１保持部材１１を保持可能に形成されている。
第２保持部材１２には、第１保持部材１１の穴部１１ｆに対応する位置に、左右一つずつの固定用ねじ穴部１２ｆが形成されている。この固定用ねじ穴部１２ｆは、第２保持部材１２の端部上に突出した突出部１２ｅのＹ軸方向に向いた軸心に形成されている。
固定用ねじ１３を穴部１１ｆに挿入して固定用ねじ穴部１２ｆに螺合することにより、第２保持部材１２に対して第１保持部材１１の移動を制限している。 "Second holding member"
As shown in FIG. 3, the second holding member 12 is disposed on the back side of the first holding member 11. The second holding member 12 is formed to be able to hold the first holding member 11 holding the curved mirror 1 on the inner peripheral side.
The second holding member 12 has one fixing screw hole portion 12f on each of the left and right sides at a position corresponding to the hole portion 11f of the first holding member 11. The fixing screw hole portion 12f is formed at the axial center of the protruding portion 12e protruding on the end portion of the second holding member 12 in the Y-axis direction.
The movement of the first holding member 11 is restricted with respect to the second holding member 12 by inserting the fixing screw 13 into the hole portion 11f and screwing it into the fixing screw hole portion 12f.

なお、固定用ねじ１３で結合する際には、スプリングワッシャ１４と平ワッシャ１５を先に固定用ねじ１３に嵌め込み、第１保持部材１１と第２保持部材１２の間に平ワッシャ１６を挟んでから、固定用ねじ１３を固定用ねじ穴１２ｆに螺合する。   When connecting with the fixing screw 13, the spring washer 14 and the flat washer 15 are first fitted into the fixing screw 13, and the flat washer 16 is sandwiched between the first holding member 11 and the second holding member 12. Then, the fixing screw 13 is screwed into the fixing screw hole 12f.

そして、第２保持部材１２には、第１保持部材１１の穴部１１ｈに対応する位置に、左右一つずつの穴部１２ｈが形成されている。この穴部１２ｈは、後側の開口の口径は広くなっているが、前側の開口の口径は小さくなり、ねじ穴状である座ぐり形状になっている。また、穴部１２ｈには、図１０に示すように、後側から圧縮バネ１８が挿入されている。   The second holding member 12 is formed with one left and right hole 12 h at a position corresponding to the hole 11 h of the first holding member 11. The hole 12h has a large opening diameter on the rear side, but a small opening diameter on the front side, and has a counterbore shape that is a screw hole shape. Further, as shown in FIG. 10, a compression spring 18 is inserted into the hole 12h from the rear side.

図４に示すように、後側から調整用ねじ１７を穴部１１ｈ及び圧縮バネ１８、穴部１２ｈに挿入し、穴部１２ｈのねじ穴部に調整用ねじ１７を螺合する。   As shown in FIG. 4, the adjusting screw 17 is inserted into the hole portion 11h, the compression spring 18, and the hole portion 12h from the rear side, and the adjusting screw 17 is screwed into the screw hole portion of the hole portion 12h.

また、第２保持部材１２の後端部には、穴部１２ｈと左右方向では同軸上に存在し、穴部１２ｈよりも曲面ミラー１の光軸に近づいた位置に、二つの調整用治具固定部１２ｊが形成されている。   In addition, two adjustment jigs are located at the rear end of the second holding member 12 coaxially with the hole 12h in the left-right direction and closer to the optical axis of the curved mirror 1 than the hole 12h. A fixed portion 12j is formed.

よって、図６及び図７に示すように、調整用治具固定部１２ｊに背面から治具部材３１を一対の冶具固定用ねじ３２により固定し、治具部材３１に形成された突起部３１ｉを第１保持部材１１に形成された調整用穴部１１ｉに係合することにより、第１保持部材１１は調整用穴部１１ｉのＹ軸と平行な中心軸を回動軸として回動可能でかつ平行移動が規制される。   Therefore, as shown in FIGS. 6 and 7, the jig member 31 is fixed to the adjustment jig fixing portion 12j from the back by a pair of jig fixing screws 32, and the projection 31i formed on the jig member 31 is fixed. By engaging with the adjustment hole 11i formed in the first holding member 11, the first holding member 11 is rotatable about a central axis parallel to the Y axis of the adjustment hole 11i as a rotation axis, and Translation is restricted.

このため、図１０に示すように、調整用ねじ１７により第１保持部材１１を第２保持部材１２に対して第２軸線（Ｙ）を回転中心とした角度調整を行う第２角度調整機構Ａ２を構成している。   For this reason, as shown in FIG. 10, the second angle adjusting mechanism A <b> 2 that adjusts the angle of the first holding member 11 with respect to the second holding member 12 with the second axis (Y) as the rotation center by the adjusting screw 17. Is configured.

また、曲面ミラー１の反射面の角度を調整してから固定用ねじ１３を締めることにより、調整後の姿勢を保持することが可能となる第２姿勢保持機構Ｂ２を構成している。   In addition, the second posture holding mechanism B2 that can hold the adjusted posture by adjusting the angle of the reflection surface of the curved mirror 1 and then tightening the fixing screw 13 is configured.

ここで、治具部材３１は第１保持部材１１を第２保持部材１２に対して調整を完了した後に外しても良いし、そのまま補強部材として残しておいてもよい。   Here, the jig member 31 may be removed after the first holding member 11 has been adjusted with respect to the second holding member 12, or may be left as a reinforcing member.

さらに、第２保持部材１２には、図３に示すように、前後方向において、突出部１２ｅと同軸上にあり、かつ突出部１２ｅよりも前側に離間した位置に、左右１つずつの穴部１２ｋが形成されている。この穴部１２ｋは、上下方向に貫通し、かつ前後方向に比べて左右方向の口径が大きくなった長穴状になっている。   Further, as shown in FIG. 3, the second holding member 12 has one hole on each of the left and right sides at a position that is coaxial with the projecting portion 12 e and spaced forward from the projecting portion 12 e in the front-rear direction. 12k is formed. The hole portion 12k has a long hole shape that penetrates in the vertical direction and has a larger diameter in the left-right direction than in the front-rear direction.

また、第２保持部材１２の穴部１２ｋの形成されている平面部１２ｍは、その左右方向に光軸から離間した辺縁部に垂直で下方向に延びた平面部１２ｎを有している。この平面部１２ｎには、左右方向において、穴部１２ｋと同軸上にあり、かつ左右方向に貫通した調整用ねじ穴部１２ｐが形成されている。   Further, the flat surface portion 12m in which the hole portion 12k of the second holding member 12 is formed has a flat surface portion 12n extending in the downward direction perpendicular to the edge portion spaced from the optical axis in the left-right direction. The planar portion 12n is formed with an adjusting screw hole portion 12p that is coaxial with the hole portion 12k in the left-right direction and penetrates in the left-right direction.

こうして、反射面の角度及び位置を調整後に固定可能に保持している曲面ミラー１及び第１保持部材１１、第２保持部材１２を組み合わせて反射面保持機構とする。   In this way, the curved mirror 1, the first holding member 11, and the second holding member 12 that are fixedly held after adjusting the angle and position of the reflecting surface are combined to form a reflecting surface holding mechanism.

「固定部材」
以上の反射面保持機構の下面側には、図５に示すように、固定部材２１が配置されている。この固定部材２１は、内周側に反射面保持機構を保持可能に形成されている。反射面保持機構は、固定部材２１の後側端部に配置されている。
固定部材２１は、前側の左右両端部に、屈折光学素子による結像光学系を内包する図示しないレンズ鏡筒に固定するための固定用係合部２１ａを有している。 `` Fixing member ''
As shown in FIG. 5, a fixing member 21 is disposed on the lower surface side of the reflection surface holding mechanism. The fixing member 21 is formed on the inner peripheral side so as to be able to hold the reflecting surface holding mechanism. The reflection surface holding mechanism is disposed at the rear end portion of the fixing member 21.
The fixing member 21 has fixing engaging portions 21a for fixing to a lens barrel (not shown) that includes an imaging optical system using a refractive optical element, at both left and right ends of the front side.

固定部材２１には、第２保持部材１２の穴部１２ｋに対応する位置に、左右１つずつの固定用ねじ穴部２１ｋが形成されている。この固定用ねじ穴部２１ｋは、固定部材２１の端部上に突出した突出部２１ｂの軸心に形成されている。
固定用ねじ２２を穴部１２ｋに挿入して固定用ねじ穴部２１ｋと螺合することにより、固定部材２１に対して第２保持部材１２の移動を制限している。 The fixing member 21 is formed with one fixing screw hole portion 21k on the left and right sides at a position corresponding to the hole portion 12k of the second holding member 12. The fixing screw hole portion 21k is formed in the axial center of the protruding portion 21b protruding on the end portion of the fixing member 21.
The movement of the second holding member 12 is restricted with respect to the fixing member 21 by inserting the fixing screw 22 into the hole portion 12k and screwing it with the fixing screw hole portion 21k.

なお、固定用ねじ２２で結合する際には、スプリングワッシャ２３と平ワッシャ２４を先に固定用ねじ２２に嵌め込み、第２保持部材１２と固定部材２１の間に平ワッシャ２５を挟んでから固定用ねじ２２を固定用ねじ穴部２１ｋと螺合する。   When connecting with the fixing screw 22, the spring washer 23 and the flat washer 24 are first fitted into the fixing screw 22, and the flat washer 25 is sandwiched between the second holding member 12 and the fixing member 21 and then fixed. The screw 22 is screwed into the fixing screw hole 21k.

そして、固定部材２１には、第２保持部材１２の調整用ねじ穴部１２ｐに対応する位置に、穴部は無く壁面である壁部２１ｐが存在している。この調整用ねじ穴部２１ｐに調整用ねじ２６が螺合されると、調整用ねじ２６が調整用ねじ穴部１２ｐを貫通して、その先端部が固定部材２１の壁部２１ｐを押す。   The fixing member 21 has a wall portion 21p that is a wall surface and does not have a hole portion at a position corresponding to the adjustment screw hole portion 12p of the second holding member 12. When the adjustment screw 26 is screwed into the adjustment screw hole portion 21p, the adjustment screw 26 penetrates the adjustment screw hole portion 12p, and the tip portion presses the wall portion 21p of the fixing member 21.

よって、図６に示すように、調整用ねじ２６により第２保持部材１２を固定部材２１に対してＸ軸方向へ平行移動させることにより、反射面の位置の調整を行う第１位置調整機構Ｃ１を構成している。   Accordingly, as shown in FIG. 6, the first position adjusting mechanism C <b> 1 that adjusts the position of the reflecting surface by moving the second holding member 12 in the X-axis direction relative to the fixing member 21 with the adjusting screw 26. Is configured.

また、図１１に示すように、反射面の位置が決定してから固定用ねじ２２を締めることにより、調整後の姿勢を保持することが可能となる第３姿勢保持機構Ｂ３を構成している。   Further, as shown in FIG. 11, the third posture holding mechanism B3 that can hold the adjusted posture by tightening the fixing screw 22 after the position of the reflecting surface is determined is configured. .

以上のように、実施形態において、曲面ミラー１の調整装置は、第１軸線（Ｘ）を回転中心とする第１角度調整機構Ａ１、第２軸線（Ｙ）を回転中心とする第２角度調整機構Ａ２、第１姿勢保持機構Ｂ１、第２姿勢保持機構Ｂ２、第３姿勢保持機構Ｂ３、第１軸線（Ｘ）方向への第１位置調整機構Ｃ１を備えている。   As described above, in the embodiment, the adjusting device for the curved mirror 1 includes the first angle adjustment mechanism A1 having the first axis (X) as the rotation center and the second angle adjustment having the second axis (Y) as the rotation center. A mechanism A2, a first posture holding mechanism B1, a second posture holding mechanism B2, a third posture holding mechanism B3, and a first position adjusting mechanism C1 in the first axis (X) direction are provided.

以上、実施形態の曲面ミラー１の調整装置によれば、第１角度調整機構Ａ１、第２角度調整機構Ａ２、第１姿勢保持機構Ｂ１、第２姿勢保持機構Ｂ２、第３姿勢保持機構Ｂ３、及び第１位置調整機構Ｃ１を互いに独立して備えることで、反射面の角度、姿勢及び位置をそれぞれ独自に調整でき、より高精度で容易に調整することができる。   As described above, according to the adjustment apparatus for the curved mirror 1 of the embodiment, the first angle adjustment mechanism A1, the second angle adjustment mechanism A2, the first attitude holding mechanism B1, the second attitude holding mechanism B2, the third attitude holding mechanism B3, Since the first position adjustment mechanism C1 is provided independently of each other, the angle, posture, and position of the reflecting surface can be independently adjusted, and can be easily adjusted with higher accuracy.

（変形例）
また、第１保持部材１１と第２保持部材１２の間にあるワッシャ１６及び／または第２保持部材１２と固定部材２１との間にある平ワッシャ２５は、そのワッシャの厚さや挟む枚数を変えることにより、反射面の上下方向の位置の調整を行うことが可能な第２位置調整機構としての機能を持たせることも可能である。 (Modification)
In addition, the washer 16 between the first holding member 11 and the second holding member 12 and / or the flat washer 25 between the second holding member 12 and the fixing member 21 changes the thickness of the washer and the number of sandwiched pieces. Thus, it is possible to provide a function as a second position adjusting mechanism capable of adjusting the position of the reflecting surface in the vertical direction.

その際に、高さ調整機構は、Ｘ軸方向において、同軸上で、かつ左右方向に離間して二箇所あるため、一方に挟むワッシャの数や厚みを他方に対して異ならせることにより、鏡軸を回転軸として反射面を回動させることも可能である。   At that time, since there are two height adjustment mechanisms on the same axis in the X-axis direction and spaced apart in the left-right direction, the number and thickness of washers sandwiched between the two can be made different from those of the other. It is also possible to rotate the reflecting surface about the axis.

（他の変形例）
以上の実施形態においては、光軸と直交する軸線を第１軸線、光軸と直交して、かつ第１軸線と直交する軸線を第２軸線としたが、これに限らず、光軸と直交する軸線と平行な軸線を第１軸線、光軸と直交して、かつ第１軸線と直交する軸線と平行な軸線を第２軸線としてもよい。
さらに、その他、具体的な細部構造等について適宜に変更可能であることは勿論である。 (Other variations)
In the above embodiment, the axis orthogonal to the optical axis is the first axis, the axis orthogonal to the optical axis, and the axis orthogonal to the first axis is the second axis. An axis parallel to the axis to be aligned may be a first axis, an axis orthogonal to the optical axis and an axis parallel to the axis orthogonal to the first axis may be the second axis.
Furthermore, it is needless to say that other specific detailed structures can be appropriately changed.
