　ケース体５０は、投影光Ｌを透光部材（以下、フロントガラスとする。）７０に向けて通過させる開口部５１を有し、この開口部５１は、透光性カバー５２で覆われている。 The case body 50 is made of, for example, black light-shielding synthetic resin, and displays a display 60 that emits the projection light L, a plane mirror 80 that reflects the projection light L emitted from the display 60 toward the mirror device 1, and The mirror device 1 having the concave mirror 10 is housed inside, and a control board is attached to the outside.
The case body 50 includes an opening 51 that allows the projection light L to pass toward a translucent member (hereinafter referred to as a windshield) 70, and the opening 51 is covered with a translucent cover 52. .
　表示器６０は、光源６１と、液晶表示素子６２とで構成される。液晶表示素子６２は、ＤＭＤ（Digital Micro Mirror Device）やＬＣＯＳ（登録商標：Liquid Crystal On Silicon）などの反射型表示素子やＴＦＴ（Thin Film transistor）液晶パネルなどの透過型表示素子等で構成される。表示器６０は、液晶表示素子６２により、図示しない制御基板からの制御信号に基づき、表示すべき表示画像Ｍを結像させ、表示画像Ｍを表示させるための投影光Ｌを平面鏡８０に向けて出射する。表示すべき表示画像Ｍとしては、例えば車両の速度やエンジン回転数を数値などで発光表示するもののほか、あらゆる表示形態を採用できるものである。
　なお、表示器６０は、平面鏡８０、ミラー装置１の凹面鏡１０、フロントガラス７０などを介して運転者に視認される際に、歪んだ虚像Ｖにならないように、それぞれの光学部材の光学特性及び配置などを考慮して予め歪ませた表示画像Ｍを表示するように制御される。 The display 60 includes a light source 61 and a liquid crystal display element 62. The liquid crystal display element 62 includes a reflective display element such as DMD (Digital Micro Mirror Device) or LCOS (registered trademark: Liquid Crystal On Silicon), a transmissive display element such as a TFT (Thin Film Transistor) liquid crystal panel, or the like. . The display 60 forms an image of the display image M to be displayed by the liquid crystal display element 62 based on a control signal from a control board (not shown), and directs the projection light L for displaying the display image M toward the plane mirror 80. Exit. As the display image M to be displayed, for example, various display forms can be adopted in addition to the display of the vehicle speed and the engine speed by numerical values.
In addition, when the display device 60 is visually recognized by the driver through the flat mirror 80, the concave mirror 10 of the mirror device 1, the windshield 70, and the like, the optical characteristics of the respective optical members and Control is performed so as to display a display image M distorted in advance in consideration of the arrangement and the like.
　平面鏡８０は、例えば合成樹脂やガラス材料からなる基板の表面に、蒸着等の手段により反射膜を形成したものであり、表示器６０から出射した投影光Ｌをミラー装置１の凹面鏡１０に向けて反射する。平面鏡８０は、ケース体５０に固定されている。 The flat mirror 80 is formed by forming a reflective film on the surface of a substrate made of, for example, a synthetic resin or glass material by means such as vapor deposition, and directs the projection light L emitted from the display device 60 toward the concave mirror 10 of the mirror device 1. reflect. The plane mirror 80 is fixed to the case body 50.
　次に、ヘッドアップディスプレイ装置１００におけるミラー装置１について説明する。
　ミラー装置１は、基板１１の前面１１ａに反射膜１１ｃが形成された凹面鏡１０と、凹面鏡１０に入射される投影光Ｌの反射角度を調整可能に、凹面鏡１０を支持するケース体５０と、を有するミラー装置１であって、基板１１の背面１１ｂに接することで、凹面鏡１０の振動を抑える制振体２０を備えて構成される。 Next, the mirror device 1 in the head-up display device 100 will be described.
The mirror device 1 includes a concave mirror 10 having a reflective film 11c formed on the front surface 11a of a substrate 11, and a case body 50 that supports the concave mirror 10 so that the reflection angle of the projection light L incident on the concave mirror 10 can be adjusted. The mirror device 1 includes a vibration damping body 20 that suppresses vibration of the concave mirror 10 by contacting the back surface 11 b of the substrate 11.
　凹面鏡１０は、合成樹脂材料、例えばＰＣ（ポリカーボネート）からなる基板１１の前面１１ａの表面に、蒸着等の手段によりアルミニウム等の金属からなる反射膜１１ｃを形成したものである。基板１１は、前面１１ａ及び裏側の背面１１ｂがともに所定の曲率を有して前面１１ａが背面１１ｂに向かって凹んだ凹状の曲面となっている。凹状の曲面を備えた基板１１は、射出成形によって成形される。
　凹面鏡１０は、図２に示すように、前面１１ａから見た（正面視）した形状が横長の略矩形状に形成され、右辺の中央側から外側に突き出す軸部１１ｄが基板１１と一体に形成されている。左右の一直線上の軸部１１ｄ（左辺の軸部は図示せず）は、ケース体５０に一体に形成された軸支部（図示せず）で回動可能に支持されている。一方の軸部１１ｄには、図１に示すように、歯車１１ｅが一体に形成され、ケース体５０に取り付けたステッピングモータ１１ｆのピニオン１１ｇが噛み合っている。ステッピングモータ１１ｆを駆動することで、ピニオン１１ｇを介して歯車１１ｅを回転することができ、凹面鏡１０の角度を変えることができる。
　これにより、凹面鏡１０は、平面鏡８０を介して入射される投影光Ｌの反射角度を調整することができる。つまり、フロントガラス７０に対する投影光Ｌの出射方向を調整し、虚像Ｖの位置を運転者の視線に合わせることができる。 The concave mirror 10 is obtained by forming a reflective film 11c made of a metal such as aluminum on the front surface 11a of a substrate 11 made of a synthetic resin material such as PC (polycarbonate) by means of vapor deposition or the like. The substrate 11 has a concave curved surface in which both the front surface 11a and the back surface 11b have a predetermined curvature, and the front surface 11a is recessed toward the back surface 11b. The substrate 11 having a concave curved surface is formed by injection molding.
As shown in FIG. 2, the concave mirror 10 is formed in a substantially rectangular shape when viewed from the front surface 11 a (front view), and a shaft portion 11 d that protrudes outward from the center side of the right side is formed integrally with the substrate 11. Has been. The left and right straight shaft portions 11 d (the left-hand shaft portion is not shown) are rotatably supported by a shaft support portion (not shown) formed integrally with the case body 50. As shown in FIG. 1, a gear 11 e is integrally formed with one shaft portion 11 d and a pinion 11 g of a stepping motor 11 f attached to the case body 50 is engaged. By driving the stepping motor 11f, the gear 11e can be rotated via the pinion 11g, and the angle of the concave mirror 10 can be changed.
Thereby, the concave mirror 10 can adjust the reflection angle of the projection light L incident through the plane mirror 80. That is, the emission direction of the projection light L with respect to the windshield 70 can be adjusted to match the position of the virtual image V with the driver's line of sight.
　制振体２０は、基板１１の背面１１ｂに沿って形成されるとともに、基板１１の背面１１ｂに対して隙間を持って対面した状態で基板１１に固定される、基板１１より剛性の高い剛性板２１と、剛性板２１と基板１１の背面１１ｂとの間の隙間に位置する押え部材２２と、を備える。
　制振体２０は、凹面鏡１０の振動の発生を抑えるものであり、図３に示すように、凹面鏡１０より剛性の高い材料、例えば、ＳＰＣＣ（冷間圧延鋼板）やＳＵＳ（ステンレス鋼）等の金属製の金属制振プレート（剛性板）２１で形成されている。
　凹面鏡１０の振動は、基板１１の両端部の軸部１１ｄを支点として基板１１が弓のように曲がる曲げ振動、２つの軸部１１ｄを結ぶ直線を中心とする回転振動、軸部１１ｄに沿う往復振動、の３つの振動が組み合わされて発生する。
　デッドアップディスプレイ装置１００では、特にミラー装置１の凹面鏡１０の曲げ振動が問題となり、ヘッドアップディスプレイ装置１００での虚像Ｖが前後にずれるようなぶれが発生する。 The damping body 20 is formed along the back surface 11b of the substrate 11 and is fixed to the substrate 11 in a state of facing the back surface 11b of the substrate 11 with a gap. 21 and a pressing member 22 positioned in a gap between the rigid plate 21 and the back surface 11 b of the substrate 11.
The damping body 20 suppresses the occurrence of vibration of the concave mirror 10, and as shown in FIG. 3, a material having higher rigidity than the concave mirror 10, such as SPCC (cold rolled steel plate) or SUS (stainless steel), is used. It is formed of a metal damping plate (rigid plate) 21 made of metal.
The vibration of the concave mirror 10 includes bending vibration in which the substrate 11 bends like a bow with the shaft portions 11d at both ends of the substrate 11 as fulcrums, rotational vibration about a straight line connecting the two shaft portions 11d, and reciprocation along the shaft portion 11d. The three vibrations are generated in combination.
In the dead-up display device 100, in particular, the bending vibration of the concave mirror 10 of the mirror device 1 becomes a problem, and blurring occurs such that the virtual image V in the head-up display device 100 shifts back and forth.
　金属制振プレート２１は、左右方向の大きさが凹面鏡１０と略同一とされ、上下方向の大きさが凹面鏡１０の略半分程度に形成されている。金属制振プレート２１は、凹面鏡１０の背面１１ｂに沿う曲面プレート２１ａと、曲面プレート２１ａに沿って左右方向に設けられる補強リブ２１ｂと、を備えている。
　金属制振プレート２１は、左右両端部が凹面鏡１０の軸部１１ｄに固定されており、両端部以外は、凹面鏡１０の背面１１ｂとの間に隙間が形成されている。これにより、凹面鏡１０は、反射角度の調整を許容した状態で、図示しないケース体５０に支持されている。
　凹面鏡１０の基板１１の背面１１ｂと制振体２０の金属制振プレート２１の間には、押え部材２２が介装されている。押え部材２２は、例えば、弾性を持つ両面テープ２３で構成され、凹面鏡１０の基板１１の中心部に当接されて金属制振プレート２１の曲面プレート２１ａと凹面鏡１０の基板１１の背面１１ｂとの隙間を接着している。 The metal damping plate 21 is substantially the same size as the concave mirror 10 in the left-right direction, and is approximately half the size of the concave mirror 10 in the vertical direction. The metal damping plate 21 includes a curved plate 21a along the back surface 11b of the concave mirror 10, and reinforcing ribs 21b provided in the left-right direction along the curved plate 21a.
Both ends of the metal damping plate 21 are fixed to the shaft portion 11d of the concave mirror 10, and a gap is formed between the metal damping plate 21 and the back surface 11b of the concave mirror 10 except for both ends. Thereby, the concave mirror 10 is supported by the case body 50 (not shown) in a state where the adjustment of the reflection angle is allowed.
A pressing member 22 is interposed between the back surface 11 b of the substrate 11 of the concave mirror 10 and the metal damping plate 21 of the damping body 20. The holding member 22 is formed of, for example, an elastic double-sided tape 23, and is in contact with the center portion of the substrate 11 of the concave mirror 10, so that the curved plate 21 a of the metal damping plate 21 and the back surface 11 b of the substrate 11 of the concave mirror 10 are formed. The gap is glued.
　このような制振体２０の金属制振プレート２１を凹面鏡１０の背面１１ｂ側に配置して軸部１１ｄを介してケース体５０に支持し、金属制振プレート２１と、凹面鏡１０の基板１１の背面１１ｂとに、押え部材２２の両面テープ２３を当接させて接着することで、両面テープ２３を介して凹面鏡１０の振動が剛性の高い金属制振プレート２１に伝達され、振動が減衰される。
　また、押え部材２２としての両面テープ２３が凹面鏡１０の背面１１ｂの中心部に当接することで、凹面鏡１０の振動モードの振幅の腹部分を抑えることになり、一層効果的に振動を減衰することができる。 Such a metal damping plate 21 of the damping body 20 is disposed on the back surface 11b side of the concave mirror 10 and supported by the case body 50 via the shaft portion 11d, and the metal damping plate 21 and the substrate 11 of the concave mirror 10 are supported. The double-sided tape 23 of the pressing member 22 is brought into contact with and adhered to the back surface 11b, whereby the vibration of the concave mirror 10 is transmitted to the highly rigid metal damping plate 21 via the double-sided tape 23, and the vibration is attenuated. .
Further, the double-sided tape 23 as the pressing member 22 abuts against the center portion of the back surface 11b of the concave mirror 10, so that the antinode of the amplitude of the vibration mode of the concave mirror 10 is suppressed, and the vibration is attenuated more effectively. Can do.
　なお、この実施の形態では、押え部材２２を、弾性を持つ両面テープ２３で構成し、制振体２０である金属制振プレート２１と凹面鏡１０との隙間を押え部材２２で接着するようにしたが、必ずしも接着する必要はなく、少なくとも一方側、例えば凹面鏡１０の基板１１の背面１１ｂとは、当てるだけでも良い。
　こうすることで、例えば、シンバルなどの打楽器で振動して音が出ているときに、指を当てると、音（振動）が止まるのと同様にして振動を抑えることができ、耐振動性を向上することができる。 In this embodiment, the holding member 22 is composed of a double-sided tape 23 having elasticity, and the gap between the metal damping plate 21 that is the damping body 20 and the concave mirror 10 is bonded by the holding member 22. However, it is not always necessary to bond them, and at least one side, for example, the back surface 11b of the substrate 11 of the concave mirror 10 may be applied.
By doing this, for example, when a sound is emitted from a percussion instrument such as a cymbal, touching your finger can suppress the vibration in the same way that the sound (vibration) stops. Can be improved.
　次に、ミラー装置１の他の実施の形態について、図４により説明する。
　この実施の形態では、制振体２０は、基板１１より剛性の高い剛性板として合成樹脂製の樹脂制振プレート２４が用いられている。樹脂制振プレート（剛性板）２４は、凹面鏡１０を図示しないケース体５０に支持するミラーホルダと兼用されている。
　すなわち制振体２０である樹脂制振プレート２４は、軸部２４ｃを備えて図示しないケース体５０に反射角度を調整可能に支持され、樹脂制振プレート２４に凹面鏡１０の基板１１が取り付けられて構成されている。
　樹脂制振プレート２４は、凹面鏡１０より剛性の高い合成樹脂等で形成される。樹脂制振プレート２４は、使用材料でなく金属制振プレート２１の場合のように、補強リブ等の構造上、剛性を高めたものであっても良い。 Next, another embodiment of the mirror device 1 will be described with reference to FIG.
In this embodiment, the damping body 20 uses a resin damping plate 24 made of synthetic resin as a rigid plate having higher rigidity than the substrate 11. The resin damping plate (rigid plate) 24 is also used as a mirror holder that supports the concave mirror 10 on a case body 50 (not shown).
That is, the resin damping plate 24 as the damping body 20 is provided with a shaft portion 24c and supported by a case body 50 (not shown) so that the reflection angle can be adjusted, and the substrate 11 of the concave mirror 10 is attached to the resin damping plate 24. It is configured.
The resin damping plate 24 is formed of a synthetic resin having higher rigidity than the concave mirror 10. The resin damping plate 24 may be one having increased rigidity due to the structure of a reinforcing rib or the like as in the case of the metal damping plate 21 instead of the material used.
　樹脂制振プレート２４は、左右方向の大きさが凹面鏡１０と略同一とされ、上下方向の大きさが凹面鏡１０の略半分程度に形成され、基板１１の背面１１ｂに対して隙間を持って対面した矩形の枠状のプレート本体２４ａと、枠状のプレート本体２４ａの前面を塞ぐホルダプレート２４ｂとを備えている。プレート本体２４ａは、左端部中央から外側に向けて軸部２４ｃが突き出して形成されている。
　ホルダプレート２４ｂには、基板１１に軸部１１ｄを備えていない凹面鏡１０が前面部に取り付けられ、４隅が接着されて固定されている。４隅の接着には、例えば両面テープ２４ｄが用いられている。
　プレート本体２４ａは、両端部の軸部２４ｃが図示しないケース体５０の軸支部に回動可能に支持される。これにより、凹面鏡１０に入射される投影光Ｌの反射角度が調整され、凹面鏡１０は、反射角度の調整を許容した状態で、図示しないケース体５０に支持されている。 The resin damping plate 24 is substantially the same size as the concave mirror 10 in the left-right direction, and is approximately half the size of the concave mirror 10 in the vertical direction, and faces the back surface 11b of the substrate 11 with a gap. A rectangular frame-shaped plate main body 24a and a holder plate 24b for closing the front surface of the frame-shaped plate main body 24a are provided. The plate body 24a is formed with a shaft portion 24c projecting outward from the center of the left end portion.
A concave mirror 10 that does not include the shaft portion 11d on the substrate 11 is attached to the front surface portion of the holder plate 24b, and four corners are bonded and fixed. For bonding at the four corners, for example, a double-sided tape 24d is used.
The plate main body 24a is rotatably supported by shaft portions 24c of both ends at a shaft support portion of the case body 50 (not shown). Thereby, the reflection angle of the projection light L incident on the concave mirror 10 is adjusted, and the concave mirror 10 is supported by the case body 50 (not shown) in a state where the adjustment of the reflection angle is allowed.
　凹面鏡１０の基板１１の背面１１ｂと制振体２０の樹脂制振プレート２４との間には、隙間が形成されて押え部材２５が介装される。押え部材２５は、金属制振プレート２１の場合と同様に、例えば、弾性を持つ両面テープ２３で構成される。両面テープ２３は、凹面鏡１０の基板１１の中心部に当接されて樹脂制振プレート２４のホルダプレート２４ｂと、凹面鏡１０の基板１１の背面１１ｂとの隙間を接着している。
　すなわち、樹脂制振プレート２４と、凹面鏡１０の基板１１の背面１１ｂの中心部に当接させて押える両面テープ２３が凹面鏡１０の振動を押える押え部材２５として機能し、４隅の両面テープ２４ｄは、凹面鏡１０の固定のために機能するものである。 Between the back surface 11b of the substrate 11 of the concave mirror 10 and the resin damping plate 24 of the damping body 20, a gap is formed and a pressing member 25 is interposed. The holding member 25 is constituted by, for example, a double-sided tape 23 having elasticity, as in the case of the metal damping plate 21. The double-sided tape 23 is in contact with the center portion of the substrate 11 of the concave mirror 10 and adheres a gap between the holder plate 24 b of the resin damping plate 24 and the back surface 11 b of the substrate 11 of the concave mirror 10.
That is, the double-sided tape 23 pressed against the resin damping plate 24 and the center of the back surface 11b of the substrate 11 of the concave mirror 10 functions as a pressing member 25 that presses the vibration of the concave mirror 10, and the double-sided tape 24d at the four corners It functions to fix the concave mirror 10.
　このような制振体２０である樹脂制振プレート（剛性板）２４を凹面鏡１０の背面１１ｂに対して隙間を持って対面させて配置し、軸部２４ｃを介して図示しないケース体５０に支持する。樹脂制振プレート２４と凹面鏡１０の基板１１の背面１１ｂとの間の隙間には、押え部材２５である両面テープ２３を当接させて互いを接着する。こうすることで、両面テープ２３を介して凹面鏡１０の振動が剛性の高い樹脂制振プレート２４に伝達され、振動が減衰される。
　また、押え部材２５である両面テープ２３が凹面鏡１０の背面１１ｂの中心部に当接することで、凹面鏡１０の振動の腹部分を抑えることになり、一層効果的に振動を減衰することができる。 A resin damping plate (rigid plate) 24, which is such a damping body 20, is arranged facing the back surface 11b of the concave mirror 10 with a gap, and supported by a case body 50 (not shown) via a shaft portion 24c. To do. In the gap between the resin damping plate 24 and the back surface 11b of the substrate 11 of the concave mirror 10, a double-sided tape 23, which is a pressing member 25, is brought into contact with and adhered to each other. By doing so, the vibration of the concave mirror 10 is transmitted to the highly rigid resin damping plate 24 via the double-sided tape 23, and the vibration is attenuated.
Further, the double-sided tape 23 that is the pressing member 25 abuts against the center portion of the back surface 11b of the concave mirror 10, so that the vibration antinode of the concave mirror 10 is suppressed, and the vibration can be attenuated more effectively.
　なお、この実施の形態では、押え部材２５を、弾性を持つ両面テープ２３で構成し、制振体２０である樹脂制振プレート（剛性板）２４と凹面鏡１０との隙間を接着するようにしたが、必ずしも接着する必要はなく、少なくとも一方側、例えば凹面鏡１０の基板１１の背面１１ｂとは、当てるだけでも良い。
　こうすることで、樹脂制振プレート２４は、金属制振プレート２１の場合と同様に、例えば、シンバルなどの打楽器で振動して音が出ているときに、指を当てると、音（振動）が止まるのと同様にして振動を抑えることができ、耐振動性を向上することができる。 In this embodiment, the pressing member 25 is composed of a double-sided tape 23 having elasticity, and a gap between the resin damping plate (rigid plate) 24 as the damping body 20 and the concave mirror 10 is bonded. However, it is not always necessary to bond them, and at least one side, for example, the back surface 11b of the substrate 11 of the concave mirror 10 may be applied.
By doing so, the resin damping plate 24, as in the case of the metal damping plate 21, for example, is vibrated by a percussion instrument such as a cymbal, and when a finger is applied, the sound (vibration) The vibration can be suppressed in the same manner as when the vibration stops, and the vibration resistance can be improved.
　次に、ミラー装置１のさらに他の実施の形態について、図５により説明する。
　この実施の形態のミラー装置１では、制振体は、図示しないケース体５０及び基板１１の背面１１ｂの間を連結する連結機構３０を備え、連結機構３０は、制振アーム３１と固定部材３２とを備えて構成されている。
　連結機構３０を構成する固定部材３２は、図示しないケース体５０に固定される。
　連結機構３０を構成する制振アーム３１は、固定部材３２に固定される一端部３１ａ、及び球状部３１ｃが形成された他端部３１ｂを備えて構成される。
　凹面鏡１０の基板１１の背面１１ｂには、球状部３１ｃを備えた他端部３１ｂが嵌まる球面受け部３３が設けられている。 Next, still another embodiment of the mirror device 1 will be described with reference to FIG.
In the mirror device 1 of this embodiment, the damping body includes a coupling mechanism 30 that couples between the case body 50 (not shown) and the back surface 11b of the substrate 11, and the coupling mechanism 30 includes the damping arm 31 and the fixing member 32. And is configured.
The fixing member 32 constituting the coupling mechanism 30 is fixed to a case body 50 (not shown).

On the back surface 11b of the substrate 11 of the concave mirror 10, there is provided a spherical receiving portion 33 into which the other end portion 31b having a spherical portion 31c is fitted.
　制振アーム３１は、例えば、弾性を有する合成樹脂製とされ、形状的にも弾性変形を許容できるように、側面形状が略Ｓ字状に形成されている。すなわち、制振アーム３１は、図５（ｂ）に示すように、一端部３１ａが斜め下方に突き出すように形成され、一端部３１ａから中間部３１ｄまでは、略直角に曲げられ、中間部３１ｄから他端部３１ｂまでが略水平に形成されて、略Ｓ字状となっている。これにより、制振アーム３１は、図５（ｂ）に示すように、中間部３１ｄの両端で、それぞれ鉛直面上（図５（ｂ）の紙面上）で弾性変形によって揺動を許容することができる。
　制振アーム３１の一端部３１ａは、先端部が円錐体状に形成されており、図示しないケース体５０に固定されたブラケット（固定部材）３２に形成した固定孔３２ａに差し込むことで固定できるようにしてある。制振アーム３１の他端部３１ｂには、球面で構成された球状部３１ｃが一体に成形されている。 The damping arm 31 is made of, for example, a synthetic resin having elasticity, and the side surface shape is formed in a substantially S shape so that elastic deformation can be allowed. That is, as shown in FIG. 5B, the damping arm 31 is formed so that one end 31a protrudes obliquely downward, and the end 31a to the intermediate portion 31d are bent at a substantially right angle, and the intermediate portion 31d. To the other end 31b are formed substantially horizontally and are substantially S-shaped. As a result, as shown in FIG. 5 (b), the damping arm 31 is allowed to swing by elastic deformation at both ends of the intermediate portion 31d on the vertical plane (on the paper surface of FIG. 5 (b)). Can do.
One end 31a of the damping arm 31 has a conical shape at the tip, and can be fixed by being inserted into a fixing hole 32a formed in a bracket (fixing member) 32 fixed to the case body 50 (not shown). It is. A spherical portion 31c made of a spherical surface is integrally formed with the other end portion 31b of the damping arm 31.
　凹面鏡１０の基板１１の背面１１ｂには、制振アーム３１の球状部３１ｃを支持する球面受け部３３が設けられている。球面受け部３３は、球状部３１ｃの凸状の球面が接触する凹状の球面を備えており、例えば図５に示すように、支持プレート３３ａの中心部に一体に成形されている。
　なお、球面受け部３３は、支持プレート３３ａとは別体に成形し、支持プレート３３ａの中心部に接着などで取り付けることもできる。
　凹面鏡１０の基板１１の背面１１ｂには、支持プレート３３ａを接着することで、球面受け部３３が凹面鏡１０の背面１１ｂの中心部に設けられる。
　球面受け部３３には、ブラケット３２の固定孔３２ａに固定された制振アーム３１の球状部３１ｃが接触した状態で当接される。 A spherical receiving portion 33 that supports the spherical portion 31 c of the damping arm 31 is provided on the back surface 11 b of the substrate 11 of the concave mirror 10. The spherical surface receiving portion 33 has a concave spherical surface with which the convex spherical surface of the spherical portion 31c comes into contact, and is formed integrally with the central portion of the support plate 33a, for example, as shown in FIG.
The spherical receiving portion 33 can be formed separately from the support plate 33a and attached to the central portion of the support plate 33a by bonding or the like.
By attaching a support plate 33a to the back surface 11b of the substrate 11 of the concave mirror 10, a spherical receiving portion 33 is provided at the center of the back surface 11b of the concave mirror 10.
The spherical receiving portion 33 is in contact with the spherical portion 31c of the damping arm 31 fixed to the fixing hole 32a of the bracket 32 in a contact state.
　図示しないケース体５０に固定したブラケット３２、凹面鏡１０の基板１１の背面１１ｂの球面受け部３３を、連結機構３０の制振アーム３１で連結することで、制振アーム３１と球面受け部３３により、凹面鏡１０の基板１１の背面１１ｂが支持プレート３３ａの球面受け部３３及び制振アーム３１の球状部３１ｃを介して図示しないケース体５０に支持された状態となる。
　これにより、凹面鏡１０に発生する振動は、制振アーム３１及びブラケット３２を介して図示しないケース体５０に伝達されて減衰され、振動が抑えられる。こうすることで、金属制振プレート２１や樹脂制振プレート２４の場合と同様に、例えば、シンバルなどの打楽器で振動して音が出ているときに、指を当てると、音（振動）が止まるのと同様にして、制振アーム３１及びブラケット３２で振動を抑えることができ、耐振動性を向上することができる
　また、制振アーム３１及びブラケット３２からなる連結機構３０を設けることによる凹面鏡１０の反射角度の調整は、制振アーム３１の略Ｓ字状の形状によって撓むことで、許容することができ、支障なく角度調整を行うことができる。
　凹面鏡１０の基板１１の背面１１ｂに支持プレート３３ａを介して球面受け部３３を当接させることで、球面受け部３３の部分に支持力が集中することなく、支持プレート３３ａに分散され、凹面鏡１０の反射膜１１ｃのゆがみなどを防止することができる。 By connecting the bracket 32 fixed to the case body 50 (not shown) and the spherical receiving portion 33 on the back surface 11b of the substrate 11 of the concave mirror 10 with the damping arm 31 of the connecting mechanism 30, the damping arm 31 and the spherical receiving portion 33 are used. The back surface 11b of the substrate 11 of the concave mirror 10 is supported by the case body 50 (not shown) via the spherical receiving portion 33 of the support plate 33a and the spherical portion 31c of the damping arm 31.
Thereby, the vibration generated in the concave mirror 10 is transmitted to the case body 50 (not shown) via the damping arm 31 and the bracket 32 and is attenuated, thereby suppressing the vibration. By doing so, as in the case of the metal damping plate 21 and the resin damping plate 24, for example, when a sound is produced by vibrating with a percussion instrument such as a cymbal, the sound (vibration) is generated when the finger is applied. Similarly to stopping, vibration can be suppressed by the vibration control arm 31 and the bracket 32, and vibration resistance can be improved. Also, the concave mirror by providing the coupling mechanism 30 including the vibration control arm 31 and the bracket 32. The adjustment of the reflection angle of 10 can be permitted by being bent by the substantially S-shaped shape of the vibration control arm 31, and the angle can be adjusted without hindrance.
By bringing the spherical receiving portion 33 into contact with the back surface 11b of the substrate 11 of the concave mirror 10 via the supporting plate 33a, the supporting force is not concentrated on the portion of the spherical receiving portion 33, but is dispersed on the supporting plate 33a. It is possible to prevent the reflection film 11c from being distorted.
