 以下、本発明の実施の形態を図面に基づいて詳細に説明する。図1Aおよび図1Bは、カメラモジュールを搭載したスマートフォンを示す図である。図2は、本発明の実施の形態に係るカメラモジュール1を簡易的に示す図である。図3は、本実施の形態に係るカメラモジュール1を側面視した構成を簡易的に示す図である。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1A and 1B are views showing a smartphone equipped with a camera module. FIG. 2 is a diagram simply showing the camera module 1 according to the embodiment of the present invention. FIG. 3 is a diagram simply showing a configuration in which the camera module 1 according to the present embodiment is viewed from the side.
 カメラモジュール1は、例えばスマートフォンM(図1A、図1B参照)、携帯電話機、デジタルカメラ、ノート型パソコン、タブレット端末、携帯型ゲーム機、車載カメラなどの薄型のカメラ搭載装置に搭載される。 The camera module 1 is mounted on a thin camera-mounted device such as a smartphone M (see FIGS. 1A and 1B), a mobile phone, a digital camera, a notebook computer, a tablet terminal, a portable game machine, and an in-vehicle camera.
 本実施の形態のカメラモジュール1の構造を説明するにあたり、直交座標系(X,Y,Z)を使用する。後述する図においても共通の直交座標系(X,Y,Z)で示している。カメラモジュール1は、カメラ搭載装置で実際に撮影が行われる場合に、例えばX方向が左右方向、Y方向が上下方向、Z方向が前後方向となるように搭載される。被写体からの光は、Z方向+側(プラス側)から入射し、屈曲してY方向+側へと導光される。カメラモジュール1のZ方向の厚さを薄くすることにより、カメラ搭載装置の薄型化を図ることができる。 In explaining the structure of the camera module 1 of the present embodiment, a Cartesian coordinate system (X, Y, Z) is used. Also in the figure described later, it is shown by a common Cartesian coordinate system (X, Y, Z). The camera module 1 is mounted so that, for example, the X direction is the left-right direction, the Y direction is the up-down direction, and the Z direction is the front-back direction when shooting is actually performed by the camera-mounted device. The light from the subject is incident from the + side (plus side) in the Z direction, bends, and is guided to the + side in the Y direction. By reducing the thickness of the camera module 1 in the Z direction, the thickness of the camera-mounted device can be reduced.
 図2から図4等に示すように、カメラモジュール1は、筐体10と、基板部20と、カバー部30と、キャップ部40と(図8等参照)、ミラー収容部50と、ミラー保持部60と、給電経路部70と(図14等参照)、駆動制御部100と、レンズ駆動部110と、撮像部120とを備える。 As shown in FIGS. 2 to 4, the camera module 1 includes a housing 10, a substrate portion 20, a cover portion 30, a cap portion 40 (see FIG. 8 and the like), a mirror accommodating portion 50, and a mirror holding portion. A unit 60, a power feeding path unit 70 (see FIG. 14 and the like), a drive control unit 100, a lens drive unit 110, and an image pickup unit 120 are provided.
 駆動制御部100は、CPU(Central Processing Unit)、ROM(Read Only Memory)、RAM(Random Access Memory)等を備える。CPUは、ROMから処理内容に応じたプログラムを読み出してRAMに展開し、展開したプログラムと協働して、後述する第1駆動部および第2駆動部を集中制御する。これにより、駆動制御部100は、筐体10に収容されるミラー収容部50および、ミラー収容部50に保持されるミラー保持部60を駆動する。 The drive control unit 100 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The CPU reads a program according to the processing content from the ROM, expands it into the RAM, and cooperates with the expanded program to centrally control the first drive unit and the second drive unit, which will be described later. As a result, the drive control unit 100 drives the mirror accommodating unit 50 housed in the housing 10 and the mirror holding unit 60 held in the mirror accommodating unit 50.
 本実施の形態において、ミラー収容部50は、Y方向を中心に回転駆動可能であり、ミラー保持部60は、X方向を中心に回転駆動可能である。そのため、ミラー保持部60に保持されるミラー素子部61は、X方向およびY方向に延びる回転軸を有しており、駆動制御部100の制御の下、当該回転軸を中心に回転する。これにより、カメラモジュール1は、撮影時に生じる振れ(振動)を光学的に補正して画像の乱れを軽減する振れ補正機能(OIS(Optical Image Stabilization)機能)を有する。 In the present embodiment, the mirror accommodating portion 50 can be rotationally driven around the Y direction, and the mirror holding portion 60 can be rotationally driven around the X direction. Therefore, the mirror element unit 61 held by the mirror holding unit 60 has a rotation axis extending in the X direction and the Y direction, and rotates about the rotation axis under the control of the drive control unit 100. As a result, the camera module 1 has a shake correction function (OIS (Optical Image Stabilization) function) that optically corrects shake (vibration) that occurs during shooting to reduce image distortion.
 図3に示すように、カメラモジュール1では、Z方向(第1方向)に沿う入射光L1が筐体10に入射される。筐体10内のミラー素子部61によって入射光L1がY方向(第2方向)の+側(一方)に進むように屈曲される。筐体10のY方向の+側には、レンズ駆動部110が設けられており、ミラー素子部61によって屈曲された反射光L2がレンズ駆動部110に入射される。筐体10、基板部20、カバー部30、キャップ部40、ミラー収容部50、ミラー保持部60および給電経路部70は、本発明の「光学素子駆動装置」に対応する。筐体10、基板部20、カバー部30、キャップ部40、ミラー収容部50、ミラー保持部60および給電経路部70については後述する。 As shown in FIG. 3, in the camera module 1, the incident light L1 along the Z direction (first direction) is incident on the housing 10. The incident light L1 is bent so as to proceed to the + side (one side) in the Y direction (second direction) by the mirror element portion 61 in the housing 10. A lens driving unit 110 is provided on the + side of the housing 10 in the Y direction, and the reflected light L2 bent by the mirror element unit 61 is incident on the lens driving unit 110. The housing 10, the substrate portion 20, the cover portion 30, the cap portion 40, the mirror accommodating portion 50, the mirror holding portion 60, and the feeding path portion 70 correspond to the "optical element driving device" of the present invention. The housing 10, the substrate portion 20, the cover portion 30, the cap portion 40, the mirror accommodating portion 50, the mirror holding portion 60, and the feeding path portion 70 will be described later.
 レンズ駆動部110は、例えば、第1固定レンズ111、第1可動レンズ112、第2可動レンズ113、第2固定レンズ114およびレンズ駆動制御部115を有する。レンズ駆動部110内では、例えば、Y方向の-側(マイナス側)から順に第1固定レンズ111、第1可動レンズ112、第2可動レンズ113、第2固定レンズ114が並んで配置されている。反射光L2は、第1固定レンズ111、第1可動レンズ112、第2可動レンズ113、第2固定レンズ114を介して、撮像部120に出力される。 The lens drive unit 110 includes, for example, a first fixed lens 111, a first movable lens 112, a second movable lens 113, a second fixed lens 114, and a lens drive control unit 115. In the lens drive unit 110, for example, the first fixed lens 111, the first movable lens 112, the second movable lens 113, and the second fixed lens 114 are arranged side by side in order from the minus side (minus side) in the Y direction. .. The reflected light L2 is output to the image pickup unit 120 via the first fixed lens 111, the first movable lens 112, the second movable lens 113, and the second fixed lens 114.
 レンズ駆動制御部115は、CPU、ROM、RAM等を備えており、第1可動レンズ112および第2可動レンズ113の移動を制御する。レンズ駆動部110では、レンズ駆動制御部115の制御の下、第1可動レンズ112および第2可動レンズ113が独立してY方向に移動する。これにより、カメラモジュール1は、無段階光学ズームおよびオートフォーカスを行う。 The lens drive control unit 115 includes a CPU, ROM, RAM, etc., and controls the movement of the first movable lens 112 and the second movable lens 113. In the lens drive unit 110, the first movable lens 112 and the second movable lens 113 independently move in the Y direction under the control of the lens drive control unit 115. As a result, the camera module 1 performs stepless optical zoom and autofocus.
 撮像部120は、レンズ駆動部110のY方向の+側の外側面に配置されており、第1固定レンズ111、第1可動レンズ112、第2可動レンズ113、第2固定レンズ114を介して反射光L2が入射するように構成されている。撮像部120は、撮像素子および撮像基板等(不図示)を有する。 The image pickup unit 120 is arranged on the outer surface on the + side of the lens drive unit 110 in the Y direction, and is via the first fixed lens 111, the first movable lens 112, the second movable lens 113, and the second fixed lens 114. It is configured so that the reflected light L2 is incident. The image pickup unit 120 includes an image pickup device, an image pickup substrate, and the like (not shown).
 撮像素子は、例えばCCD(Charge Coupled Device)型イメージセンサ、CMOS(Complementary Metal Oxide Semiconductor)型イメージセンサ等により構成される。撮像素子は、撮像基板に実装され、ボンディングワイヤーを介して基板上の配線に電気的に接続される。撮像素子は、第1固定レンズ111、第1可動レンズ112、第2可動レンズ113、第2固定レンズ114により結像された被写体像を撮像し、被写体像に対応する電気信号を出力する。 The image sensor is composed of, for example, a CCD (Charge Coupled Device) type image sensor, a CMOS (Complementary Metal Oxide Semiconductor) type image sensor, or the like. The image pickup device is mounted on the image pickup board and is electrically connected to the wiring on the board via the bonding wire. The image sensor captures a subject image formed by the first fixed lens 111, the first movable lens 112, the second movable lens 113, and the second fixed lens 114, and outputs an electric signal corresponding to the subject image.
 また、撮像部120の撮像基板には、プリント配線基板(不図示)が電気的に接続され、このプリント配線基板を介して撮像素子への給電および撮像素子で撮像された被写体像の電気信号の出力が行われる。当該電気信号は、カメラ搭載装置に設けられる撮像制御部200に出力される。撮像制御部200は、CPU、ROM、RAM等を備えており、カメラモジュール1で得られた画像情報を処理する。撮像制御部200は、カメラ搭載装置に搭載されていれば良いが、カメラモジュール1に内蔵されていても良い。 Further, a printed wiring board (not shown) is electrically connected to the image pickup board of the image pickup unit 120, and power is supplied to the image pickup element via the printed wiring board and the electric signal of the subject image captured by the image pickup element is transmitted. Output is done. The electric signal is output to the image pickup control unit 200 provided in the camera-mounted device. The image pickup control unit 200 includes a CPU, ROM, RAM, and the like, and processes the image information obtained by the camera module 1. The image pickup control unit 200 may be mounted on the camera mounting device, but may be mounted on the camera module 1.
 次に、筐体10、基板部20、カバー部30、キャップ部40(図8等参照)、ミラー収容部50、ミラー保持部60および給電経路部70(図14等参照)の詳細について説明する。筐体10、基板部20、カバー部30、キャップ部40、ミラー収容部50、ミラー保持部60および給電経路部70は、本発明の「光学素子駆動装置」に対応する。 Next, details of the housing 10, the board portion 20, the cover portion 30, the cap portion 40 (see FIG. 8 and the like), the mirror accommodating portion 50, the mirror holding portion 60 and the feeding path portion 70 (see FIG. 14 and the like) will be described. .. The housing 10, the substrate portion 20, the cover portion 30, the cap portion 40, the mirror accommodating portion 50, the mirror holding portion 60, and the feeding path portion 70 correspond to the "optical element driving device" of the present invention.
 まず、筐体10について説明する。図4に示すように、筐体10は、カバー部30、キャップ部40、ミラー収容部50、ミラー保持部60および給電経路部70を収容しており、例えば全体として直方体形状を有する。筐体10は、入射壁11と、出射壁12と、一対の側壁13と、底壁14とを有する。 First, the housing 10 will be described. As shown in FIG. 4, the housing 10 accommodates a cover portion 30, a cap portion 40, a mirror accommodating portion 50, a mirror holding portion 60, and a feeding path portion 70, and has, for example, a rectangular parallelepiped shape as a whole. The housing 10 has an incident wall 11, an emitted wall 12, a pair of side walls 13, and a bottom wall 14.
 入射壁11は、筐体10におけるZ方向の+側の壁であり、入射光L1が入射する側に位置する。入射壁11には、入射光L1が筐体10の内部に入るための開口11Aが設けられている。開口11Aは、筐体10内に収容される、ミラー素子部61に対応する位置に位置する。開口11AのY方向の長さは、ミラーのY方向の移動範囲に対応した長さである(図28、図29等参照)。 The incident wall 11 is a wall on the + side in the Z direction of the housing 10, and is located on the side where the incident light L1 is incident. The incident wall 11 is provided with an opening 11A for allowing the incident light L1 to enter the inside of the housing 10. The opening 11A is located at a position corresponding to the mirror element portion 61 housed in the housing 10. The length of the opening 11A in the Y direction corresponds to the moving range of the mirror in the Y direction (see FIGS. 28, 29, etc.).
 これにより、例えば撮影時の振動等によって開口11Aに対する入射光L1の位置関係がずれても、駆動制御部100の制御の下、ミラー素子部61が適宜移動することにより、開口11Aを介して入射した入射光L1をミラー素子部61が後述する開口12Aの範囲内に屈曲させるようになっている。 As a result, even if the positional relationship of the incident light L1 with respect to the aperture 11A shifts due to vibration during shooting, for example, the mirror element unit 61 moves appropriately under the control of the drive control unit 100, so that the incident light L1 is incident through the aperture 11A. The incident light L1 is bent by the mirror element unit 61 within the range of the opening 12A described later.
 出射壁12は、筐体10におけるY方向の+側の側壁であり、入射光L1がミラー素子部61から反射された反射光L2が出射する側に位置する。出射壁12には、反射光L2が筐体10の外側に出力されるための開口12Aが設けられている。 The emission wall 12 is a side wall on the + side in the Y direction of the housing 10, and is located on the side where the incident light L1 is emitted from the reflected light L2 reflected from the mirror element portion 61. The emission wall 12 is provided with an opening 12A for outputting the reflected light L2 to the outside of the housing 10.
 開口12Aは、X方向に延びる略円状に形成されている。そして、出射壁12のY方向の-側の面には、ミラー収容部50の回転軸周りに延びるように設けられ、開口12Aに沿う円弧状ガイド溝部12Bが設けられている(図14参照)。円弧状ガイド溝部12Bは、Z方向の+側に凸となる円弧状に構成され、底(Y方向の+側)に向かうほど先細りとなるような溝形状を有する。出射壁12は、円弧状ガイド溝部12Bを有することで、回転軸がY方向に沿うように、ミラー収容部50を支持する。出射壁12は、本発明の「固定部」に対応する。円弧状ガイド溝部12Bは、本発明の「固定部の溝部」に対応する。 The opening 12A is formed in a substantially circular shape extending in the X direction. An arcuate guide groove 12B along the opening 12A is provided on the Y-side surface of the emission wall 12 so as to extend around the rotation axis of the mirror accommodating portion 50 (see FIG. 14). .. The arc-shaped guide groove portion 12B is configured in an arc shape that is convex on the + side in the Z direction, and has a groove shape that tapers toward the bottom (+ side in the Y direction). The emission wall 12 has an arcuate guide groove portion 12B to support the mirror accommodating portion 50 so that the rotation axis is along the Y direction. The exit wall 12 corresponds to the "fixed portion" of the present invention. The arc-shaped guide groove portion 12B corresponds to the “groove portion of the fixed portion” of the present invention.
 一対の側壁13は、筐体10におけるX方向の両側の側壁であり、入射壁11および出射壁12と一体に構成されている。図5に示すように、一対の側壁13におけるZ方向の-側の端面には、カバー部30が係合する被係合部13Aが設けられている。 The pair of side walls 13 are side walls on both sides of the housing 10 in the X direction, and are integrally formed with the incident wall 11 and the exit wall 12. As shown in FIG. 5, an engaged portion 13A to which the cover portion 30 engages is provided on the end face on the − side in the Z direction of the pair of side walls 13.
 底壁14は、筐体10におけるZ方向の-側の壁である。つまり、底壁14は、Z方向においてミラー収容部50に対して入射光L1の入射側とは反対側に配置されている。底壁14は、一対の側壁13のZ方向の-側の端面に対して着脱可能に設けられている。底壁14には、カメラ搭載装置における電源から電力が供給される基板部20が設けられている。 The bottom wall 14 is the wall on the negative side in the Z direction of the housing 10. That is, the bottom wall 14 is arranged on the side opposite to the incident side of the incident light L1 with respect to the mirror accommodating portion 50 in the Z direction. The bottom wall 14 is detachably provided with respect to the end faces on the − side in the Z direction of the pair of side walls 13. The bottom wall 14 is provided with a substrate portion 20 to which electric power is supplied from a power source in the camera mounting device.
 次に、基板部20について説明する。基板部20は、ミラー収容部50から離間してY方向に沿って配置されており、複数の入出力端子21を有している。基板部20は、筐体10外部からの電気信号を入力、または、筐体10内部からの電気信号を出力可能に構成されている。複数の入出力端子21のうち、基板部20におけるY方向の+側の入出力端子21Aは、ミラー収容部50との間で給電を可能とする端子12Cが接続される。 Next, the board portion 20 will be described. The board portion 20 is arranged along the Y direction apart from the mirror accommodating portion 50, and has a plurality of input / output terminals 21. The board portion 20 is configured to be able to input an electric signal from the outside of the housing 10 or output an electric signal from the inside of the housing 10. Of the plurality of input / output terminals 21, the input / output terminal 21A on the + side in the Y direction of the board unit 20 is connected to the terminal 12C capable of supplying power to and from the mirror accommodating unit 50.
 端子12Cは、出射壁12にインサートされており、基板部20が一対の側壁13に装着された際に基板部20の入出力端子21Aと接触する位置に設けられている。端子12Cは、給電経路部70を介してミラー収容部50と接続される(図31参照)。 The terminal 12C is inserted into the emission wall 12, and is provided at a position where the board portion 20 comes into contact with the input / output terminal 21A of the board portion 20 when the board portion 20 is mounted on the pair of side walls 13. The terminal 12C is connected to the mirror accommodating portion 50 via the feeding path portion 70 (see FIG. 31).
 これにより、基板部20は、ミラー収容部50に給電可能となる。なお、基板部20の入出力端子21Aは、正極側と負極側とでそれぞれ3つずつ設けられている。例えば正極側の入出力端子21Aは、基板部20のY方向の+側の端部における、X方向の-側に配置され、負極側の入出力端子21Aは、基板部20のY方向の+側の端部における、X方向の+側に配置されている。 As a result, the board portion 20 can supply power to the mirror accommodating portion 50. The input / output terminals 21A of the substrate portion 20 are provided on the positive electrode side and the negative electrode side, respectively, three by three. For example, the input / output terminal 21A on the positive electrode side is arranged on the-side in the X direction at the end on the + side in the Y direction of the substrate portion 20, and the input / output terminal 21A on the negative electrode side is located on the + side in the Y direction of the substrate portion 20. It is arranged on the + side in the X direction at the end of the side.
 また、基板部20には、ミラー収容部50をY方向に沿う回転軸(第1回転軸)を中心として回転駆動させるための第1駆動部を構成する共振部22が設けられている。また、図6に示すように、ミラー収容部50のZ方向の-側には、振動する共振部22と接触することでミラー収容部50を回転駆動させる予圧をミラー収容部50に付与する接触部50Aが設けられている。 Further, the substrate portion 20 is provided with a resonance portion 22 constituting a first drive portion for rotationally driving the mirror accommodating portion 50 around a rotation shaft (first rotation shaft) along the Y direction. Further, as shown in FIG. 6, on the negative side of the mirror accommodating portion 50 in the Z direction, a contact that applies a preload to the mirror accommodating portion 50 to rotationally drive the mirror accommodating portion 50 by contacting with the vibrating resonance portion 22. A portion 50A is provided.
 共振部22および接触部50Aは、ミラー収容部50のY方向周りの回転駆動の第1駆動部となる超音波モータを構成する。なお、第1駆動部としては、VCM(Voice Coil Motor)等、超音波モータ以外のものでも良い。 The resonance portion 22 and the contact portion 50A constitute an ultrasonic motor that serves as a first drive portion for rotationally driving the mirror accommodating portion 50 around the Y direction. The first drive unit may be something other than an ultrasonic motor, such as a VCM (Voice Coil Motor).

 この第2規制壁522Aにより、ミラー保持部60のZ方向の+側への移動が規制される(図28および図29参照)。 The second restricting wall 522A restricts the movement of the mirror holding portion 60 to the + side in the Z direction (see FIGS. 28 and 29).
 また、第1摺動壁512の規制カバー部52に覆われる部分には、収容側基板部53が設けられている。図18に示すように、収容側基板部53は、第1摺動壁512からY方向の-側に突出する突起に係合可能に構成されている。収容側基板部53は、本体基板部531と延出基板部532とを有する。 Further, a housing side substrate portion 53 is provided in a portion of the first sliding wall 512 covered by the regulation cover portion 52. As shown in FIG. 18, the accommodating side substrate portion 53 is configured to be engageable with a protrusion protruding from the first sliding wall 512 on the − side in the Y direction. The accommodating side substrate portion 53 includes a main body substrate portion 531 and an extended substrate portion 532.
 本体基板部531は、X方向の-側の経路保持部512Bから、X方向の+側の経路保持部512Bまで延びて構成されている。本体基板部531は、第1摺動溝部512Aと重ならないように、第1摺動溝部512Aに対応する部分がZ方向の+側に切り欠かれている。 The main body board portion 531 is configured to extend from the path holding portion 512B on the-side in the X direction to the path holding portion 512B on the + side in the X direction. The main body substrate portion 531 has a portion corresponding to the first sliding groove portion 512A cut out on the + side in the Z direction so as not to overlap with the first sliding groove portion 512A.
 本体基板部531のX方向の両端部、つまり、経路保持部512Bに対応する部分には、給電経路部70と接続される第1給電端子531Aが設けられている。本実施の形態では、第1給電端子531Aは、本体基板部531におけるX方向の両端部のそれぞれにおいて3つずつ設けられている。 A first power supply terminal 531A connected to the power supply path portion 70 is provided at both ends of the main body board portion 531 in the X direction, that is, a portion corresponding to the path holding portion 512B. In the present embodiment, three first power feeding terminals 531A are provided at both ends of the main body board portion 531 in the X direction.
 また、本体基板部531のX方向の中央部には、上述の共振部511Bに接続される端子511C(図17参照)に接続される第2給電端子531Bが設けられる。 Further, a second feeding terminal 531B connected to the terminal 511C (see FIG. 17) connected to the resonance portion 511B described above is provided at the center portion of the main body board portion 531 in the X direction.
 延出基板部532は、本体基板部531のX方向の-側の端部から側壁514に沿ってY方向の+側に延出する。延出基板部532には、位置検出部532Aが配置される。 The extension board portion 532 extends from the end on the-side in the X direction of the main body board portion 531 to the + side in the Y direction along the side wall 514. A position detection unit 532A is arranged on the extension board unit 532.
 位置検出部532Aは、磁力を検出可能な、例えば磁気抵抗効果素子等である。また、図17に示すように、X方向の+側の側壁514には、X方向に貫通した位置検出孔514Cが形成されている。位置検出部532Aは、位置検出孔514Cに対応する位置に配置される。これにより、位置検出部532Aは、収容筐体51の内部のミラー保持部60と対向可能に配置され、ミラー保持部60(マグネット部623)の位置を磁気的に検出する。 The position detection unit 532A is, for example, a magnetoresistive effect element that can detect a magnetic force. Further, as shown in FIG. 17, a position detection hole 514C penetrating in the X direction is formed on the side wall 514 on the + side in the X direction. The position detection unit 532A is arranged at a position corresponding to the position detection hole 514C. As a result, the position detection unit 532A is arranged so as to face the mirror holding unit 60 inside the housing housing 51, and magnetically detects the position of the mirror holding unit 60 (magnet unit 623).
 図16、図20および図21に示すように、第1摺動部54は、キャップ部40の環状ガイド溝部41と、第1摺動壁512の第1摺動溝部512Aとの間に介在する球状部材であり、キャップ部40との間に介在することでミラー収容部50を支持する面を構成する。第1摺動部54は、合計で9つ設けられており、第1摺動溝部512Aの3箇所に3つずつ分離して設けられている。3つ並んで配置される第1摺動部54のうち、真ん中に配置される第1摺動部54同士は、約120度の間隔を有する。第1摺動部54は、本発明の「介在部」に対応する。 As shown in FIGS. 16, 20 and 21, the first sliding portion 54 is interposed between the annular guide groove portion 41 of the cap portion 40 and the first sliding groove portion 512A of the first sliding wall 512. It is a spherical member, and is interposed between the cap portion 40 and the cap portion 40 to form a surface that supports the mirror accommodating portion 50. A total of nine first sliding portions 54 are provided, and three first sliding portions 54 are provided separately at three locations of the first sliding groove portion 512A. Of the three first sliding portions 54 arranged side by side, the first sliding portions 54 arranged in the middle have an interval of about 120 degrees. The first sliding portion 54 corresponds to the "intervening portion" of the present invention.
 また、3つ並んで配置される第1摺動部54のうち、真ん中に配置される第1摺動部54は、それ以外の第1摺動部54よりも径が大きく構成されている。そのため、真ん中に配置される第1摺動部54が、環状ガイド溝部41と第1摺動溝部512Aとの間を摺動する(図21参照)。つまり、第1摺動部54は、環状ガイド溝部41と第1摺動溝部512Aとに、ミラー収容部50の回転に伴って摺動可能に収容されている。 Further, among the three first sliding portions 54 arranged side by side, the first sliding portion 54 arranged in the middle has a larger diameter than the other first sliding portions 54. Therefore, the first sliding portion 54 arranged in the center slides between the annular guide groove portion 41 and the first sliding groove portion 512A (see FIG. 21). That is, the first sliding portion 54 is slidably accommodated in the annular guide groove portion 41 and the first sliding groove portion 512A as the mirror accommodating portion 50 rotates.
 このように、キャップ部40と、第1摺動壁512との間を介在する第1摺動部54が球状部材で構成されるので、ミラー収容部50がY方向を中心に回転した際、環状ガイド溝部41と第1摺動溝部512Aとの間を第1摺動部54が転がりながら摺動する。つまり、第1摺動部54は、ミラー収容部50の回転に従動する。これにより、ミラー収容部50のY方向を中心とした回転をスムーズにすることができる。 As described above, since the first sliding portion 54 interposed between the cap portion 40 and the first sliding wall 512 is composed of a spherical member, when the mirror accommodating portion 50 rotates about the Y direction, The first sliding portion 54 slides while rolling between the annular guide groove portion 41 and the first sliding groove portion 512A. That is, the first sliding portion 54 is driven by the rotation of the mirror accommodating portion 50. As a result, the rotation of the mirror accommodating portion 50 about the Y direction can be smoothed.
 また、キャップ部40は、付勢部33(環状部331)によってミラー収容部50に向けて付勢されることから(図13参照)、キャップ部40は、Y方向の-側の端部において、ミラー収容部50のY方向(スラスト方向)における荷重を受けるスラスト軸受として機能する。これにより、カメラモジュール1において、Y方向にかかる負荷を低減することができる。 Further, since the cap portion 40 is urged toward the mirror accommodating portion 50 by the urging portion 33 (annular portion 331) (see FIG. 13), the cap portion 40 is located at the end on the − side in the Y direction. , Functions as a thrust bearing that receives a load in the Y direction (thrust direction) of the mirror accommodating portion 50. As a result, the load applied to the camera module 1 in the Y direction can be reduced.
 第1間隔保持部55は、複数の第1摺動部54の間隔を保持する平板部材であり、Y方向に直交するように、第1摺動壁512の第1摺動溝部512Aに対応する部分とキャップ部40と間に挟まれて配置される。第1間隔保持部55は、第1摺動壁512の第1摺動溝部512Aに対応する部分およびキャップ部40に対応した円形状に構成されている。第1間隔保持部55は、本発明の「間隔保持部」に対応する。 The first spacing holding portion 55 is a flat plate member that holds the spacing between the plurality of first sliding portions 54, and corresponds to the first sliding groove portion 512A of the first sliding wall 512 so as to be orthogonal to the Y direction. It is arranged so as to be sandwiched between the portion and the cap portion 40. The first spacing holding portion 55 is configured in a circular shape corresponding to the portion corresponding to the first sliding groove portion 512A of the first sliding wall 512 and the cap portion 40. The first interval holding unit 55 corresponds to the "interval holding unit" of the present invention.
 第1間隔保持部55は、3つの第1摺動部54が並んで配置可能な程度の孔55Aを3つ有している。3つの孔55Aのそれぞれに、3つの第1摺動部54が配置される。第1間隔保持部55における孔55A以外の部分551は、第1摺動溝部512Aの環状の開口部を複数の区分開口部に仕切って、複数の第1摺動部54を個別に配置させる仕切り部を構成する。3つの孔55Aは、第1摺動溝部512Aにおける複数の区分開口部に対応する位置に配置されている。言い換えると、第1間隔保持部55は、仕切り部を3つの孔55Aにより構成する平板部材である。 The first spacing holding portion 55 has three holes 55A to which three first sliding portions 54 can be arranged side by side. Three first sliding portions 54 are arranged in each of the three holes 55A. In the portion 551 other than the hole 55A in the first spacing holding portion 55, the annular opening of the first sliding groove portion 512A is partitioned into a plurality of compartmentalized openings, and the plurality of first sliding portions 54 are individually arranged. Make up the part. The three holes 55A are arranged at positions corresponding to a plurality of division openings in the first sliding groove portion 512A. In other words, the first spacing holding portion 55 is a flat plate member in which the partition portion is composed of three holes 55A.
 これにより、ミラー収容部50がY方向に沿う回転軸を中心として回転した際、ミラー収容部50の回転方向において、各第1摺動部54の間隔が所定の角度範囲内で並ぶように、当該間隔が保持される。その結果、回転中心(第1間隔保持部55の中心)に対して、約120度の間隔が保持されるので、各第1摺動部54の間の配置バランスが良くなり、ひいてはミラー収容部50の回転を安定化させることができる。 As a result, when the mirror accommodating portion 50 rotates about the rotation axis along the Y direction, the intervals between the first sliding portions 54 are arranged within a predetermined angle range in the rotation direction of the mirror accommodating portion 50. The interval is maintained. As a result, an interval of about 120 degrees is maintained with respect to the center of rotation (the center of the first interval holding portion 55), so that the arrangement balance between the first sliding portions 54 is improved, and by extension, the mirror accommodating portion. The rotation of 50 can be stabilized.
 また、第1間隔保持部55が第1摺動溝部512A(収容筐体51)や環状ガイド溝部41(キャップ部40)とは別部材で構成されることで、第1摺動部54の位置調整をする際に、収容筐体51やキャップ部40を作り直す必要がなくなる。具体的には、第1間隔保持部55の孔55Aをあける位置を適宜調整すれば良いので、第1摺動部54の位置調整をするための設計(作業)工数を大幅に削減することができる。 Further, the position of the first sliding portion 54 is formed by the first spacing holding portion 55 being formed of a member separate from the first sliding groove portion 512A (accommodating housing 51) and the annular guide groove portion 41 (cap portion 40). When making adjustments, it is not necessary to remake the housing housing 51 and the cap portion 40. Specifically, since the position of the hole 55A of the first spacing holding portion 55 may be appropriately adjusted, the design (work) man-hours for adjusting the position of the first sliding portion 54 can be significantly reduced. can.
 また、第1間隔保持部55が平板部材で構成されているので、孔55Aの位置を調節しやすく、ひいては上記の設計工数を大幅に削減することができる。 Further, since the first spacing holding portion 55 is made of a flat plate member, the position of the hole 55A can be easily adjusted, and the above-mentioned design man-hours can be significantly reduced.
 また、本実施の形態では、第1摺動溝部512Aおよび環状ガイド溝部41が環状に延在して構成されているので、複数の第1摺動部54を一括で収容可能となっている。そのため、溝部内で第1摺動部の位置を規定するような構成と比較して、各第1摺動部54を溝部内に配置しやすく、第1間隔保持部55により各第1摺動部54の間隔を調整しやすくすることができる。 Further, in the present embodiment, since the first sliding groove portion 512A and the annular guide groove portion 41 are configured to extend in an annular shape, a plurality of first sliding portions 54 can be accommodated at once. Therefore, it is easier to arrange each first sliding portion 54 in the groove portion as compared with a configuration in which the position of the first sliding portion is defined in the groove portion, and each first sliding portion is easily arranged by the first spacing holding portion 55. The spacing between the portions 54 can be easily adjusted.
 また、第1間隔保持部55が平板部材で構成されることで、Y方向(反射光L2の出射方向)で幅を取ることがないので、収容筐体51のY方向の大きさを小さくすることができる。 Further, since the first spacing holding portion 55 is made of a flat plate member, the width is not taken in the Y direction (the emission direction of the reflected light L2), so that the size of the accommodation housing 51 in the Y direction is reduced. be able to.
 また、第1間隔保持部55は、例えば、ミラー収容部50に対して固定状態で配置されている。具体的には、第1間隔保持部55は、例えば接着剤等で第1摺動部54に対応する部分に固定されている。 Further, the first interval holding portion 55 is arranged in a fixed state with respect to the mirror accommodating portion 50, for example. Specifically, the first interval holding portion 55 is fixed to a portion corresponding to the first sliding portion 54 with, for example, an adhesive or the like.
 このため、第1摺動部54とミラー収容部50との位置関係がずれるような力が発生しても、第1間隔保持部55がミラー収容部50に固定されているため、第1摺動部54とミラー収容部50との位置関係が一定の範囲内(孔55Aの範囲内)に維持される。 Therefore, even if a force that causes the positional relationship between the first sliding portion 54 and the mirror accommodating portion 50 to shift is generated, the first spacing holding portion 55 is fixed to the mirror accommodating portion 50, so that the first sliding portion 55 is fixed. The positional relationship between the moving portion 54 and the mirror accommodating portion 50 is maintained within a certain range (within the range of the hole 55A).
 本実施の形態では、第1摺動部54が球状部材であるので、ミラー収容部50がY方向に沿う回転軸を中心として回転した場合、第1摺動部54が転がりながら摺動する。そのため、第1摺動部54とミラー収容部50との位置関係がずれるような力が発生しても、スムーズにミラー収容部50を回転させることができる。 In the present embodiment, since the first sliding portion 54 is a spherical member, when the mirror accommodating portion 50 rotates about a rotation axis along the Y direction, the first sliding portion 54 slides while rolling. Therefore, even if a force is generated that causes the positional relationship between the first sliding portion 54 and the mirror accommodating portion 50 to shift, the mirror accommodating portion 50 can be smoothly rotated.
 また、第1摺動溝部512AがY方向の+側に向かうほど先細りとなる形状であり、かつ、環状ガイド溝部41がY方向の-側に向かうほど先細りとなる形状であるので、各溝部において、第1摺動部54を2点で支持することができる。その結果、第1摺動部54の位置を各溝部内で安定させやすくすることができる。 Further, the first sliding groove portion 512A has a shape that tapers toward the + side in the Y direction, and the annular guide groove portion 41 has a shape that tapers toward the − side in the Y direction. , The first sliding portion 54 can be supported at two points. As a result, the position of the first sliding portion 54 can be easily stabilized in each groove portion.
 図22、図23および図24に示すように、第2摺動部56は、上述の出射壁12の円弧状ガイド溝部12Bと、第2摺動壁513の第2摺動溝部513Bとの間に介在する球状部材であり、出射壁12との間に介在することでミラー収容部50を支持する面を構成する。第2摺動部56は、合計で3つ設けられており、円弧状ガイド溝部12Bおよび第2摺動溝部513Bにおける3箇所に分離して設けられている。3つの第2摺動部56のうち、隣り合う2つの第2摺動部56は、所定の間隔を空けて配置されている。第2摺動部56は、本発明の「介在部」に対応する。 As shown in FIGS. 22, 23 and 24, the second sliding portion 56 is located between the arcuate guide groove portion 12B of the above-mentioned emission wall 12 and the second sliding groove portion 513B of the second sliding wall 513. It is a spherical member interposed in the mirror accommodating portion 50, and constitutes a surface supporting the mirror accommodating portion 50 by interposing between the spherical member and the exit wall 12. A total of three second sliding portions 56 are provided, and the second sliding portions 56 are provided separately at three locations in the arcuate guide groove portion 12B and the second sliding groove portion 513B. Of the three second sliding portions 56, two adjacent second sliding portions 56 are arranged at predetermined intervals. The second sliding portion 56 corresponds to the "intervening portion" of the present invention.
 所定の間隔は、円弧状ガイド溝部12Bおよび第2摺動溝部513Bにおける円弧の形状に応じて設定可能な角度であり、少なくとも120度未満の角度である。本実施の形態では、約90度程度になっている(図23参照)。 The predetermined interval is an angle that can be set according to the shape of the arc in the arc-shaped guide groove portion 12B and the second sliding groove portion 513B, and is at least an angle of less than 120 degrees. In this embodiment, the temperature is about 90 degrees (see FIG. 23).
 このように、出射壁12と、第2摺動壁513との間を介在する第2摺動部56が球状部材で構成されるので、ミラー収容部50がY方向に沿う回転軸を中心に回転した際、円弧状ガイド溝部12Bと第2摺動溝部513Bとの間を第2摺動部56が転がりながら摺動する。つまり、第2摺動部56は、円弧状ガイド溝部12Bと第2摺動溝部513Bとに、ミラー収容部50の回転に伴って摺動可能に収容されており、ミラー収容部50の回転に従動する。これにより、ミラー収容部50のY方向を中心とした回転をスムーズにすることができる。 As described above, since the second sliding portion 56 interposed between the exit wall 12 and the second sliding wall 513 is composed of a spherical member, the mirror accommodating portion 50 is centered on the rotation axis along the Y direction. When rotated, the second sliding portion 56 slides between the arc-shaped guide groove portion 12B and the second sliding groove portion 513B while rolling. That is, the second sliding portion 56 is slidably accommodated in the arcuate guide groove portion 12B and the second sliding groove portion 513B as the mirror accommodating portion 50 rotates, and the mirror accommodating portion 50 rotates. Follow. As a result, the rotation of the mirror accommodating portion 50 about the Y direction can be smoothed.
 第2間隔保持部57は、複数の第2摺動部56の間隔を保持する平板部材であり、Y方向に直交するように、第2摺動壁513の第2摺動溝部513Bに対応する部分と、出射壁12の円弧状ガイド溝部12Bに対応する部分との間に挟まれて配置される。第2間隔保持部57は、第2摺動溝部513Bに対応する部分および円弧状ガイド溝部12Bに対応する部分に対応した、Z方向の+側に凸となる円弧状に構成されている。第2間隔保持部57は、本発明の「間隔保持部」に対応する。 The second spacing holding portion 57 is a flat plate member that holds the spacing between the plurality of second sliding portions 56, and corresponds to the second sliding groove portion 513B of the second sliding wall 513 so as to be orthogonal to the Y direction. It is sandwiched between the portion and the portion corresponding to the arcuate guide groove portion 12B of the emission wall 12. The second spacing holding portion 57 is configured in an arc shape that is convex on the + side in the Z direction, corresponding to the portion corresponding to the second sliding groove portion 513B and the portion corresponding to the arc-shaped guide groove portion 12B. The second interval holding unit 57 corresponds to the "interval holding unit" of the present invention.
 第2間隔保持部57は、1つの第2摺動部56が配置可能な程度の孔57Aを3つ有している。3つの孔57Aのそれぞれに、第2摺動部56が配置される。第2間隔保持部57における孔57A以外の部分570は、第2摺動溝部513Bの環状の開口部を複数の区分開口部に仕切って、複数の第2摺動部56を個別に配置させる仕切り部を構成する。3つの孔57Aは、第2摺動溝部513Bにおける複数の区分開口部に対応する位置に配置されている。言い換えると、第2間隔保持部57は、仕切り部を3つの孔57Aにより構成する平板部材である。これにより、第2間隔保持部57は、ミラー収容部50の回転方向において、3つの第2摺動部56が等間隔で並ぶように、3つの第2摺動部56を保持する。 The second spacing holding portion 57 has three holes 57A to which one second sliding portion 56 can be arranged. A second sliding portion 56 is arranged in each of the three holes 57A. In the portion 570 other than the hole 57A in the second spacing holding portion 57, the annular opening of the second sliding groove portion 513B is partitioned into a plurality of compartmentalized openings, and the plurality of second sliding portions 56 are individually arranged. Make up the part. The three holes 57A are arranged at positions corresponding to a plurality of division openings in the second sliding groove portion 513B. In other words, the second spacing holding portion 57 is a flat plate member whose partition portion is composed of three holes 57A. As a result, the second gap holding portion 57 holds the three second sliding portions 56 so that the three second sliding portions 56 are lined up at equal intervals in the rotation direction of the mirror accommodating portion 50.
 そのため、ミラー収容部50がY方向に沿う回転軸を中心として回転した際、ミラー収容部50の回転方向において、各第2摺動部56の間隔が所定の角度範囲内で並ぶように、当該間隔が保持される。その結果、各第2摺動部56の間の配置バランスが良くなるため、ミラー収容部50の回転を安定化させることができる。 Therefore, when the mirror accommodating portion 50 rotates about the rotation axis along the Y direction, the distance between the second sliding portions 56 is arranged within a predetermined angle range in the rotation direction of the mirror accommodating portion 50. The interval is maintained. As a result, the arrangement balance between the second sliding portions 56 is improved, so that the rotation of the mirror accommodating portion 50 can be stabilized.
 また、第2間隔保持部57が第2摺動溝部513B(収容筐体51)や円弧状ガイド溝部12B(出射壁12)とは別部材で構成されることで、第2摺動部56の位置調整をする際に、収容筐体51や出射壁12を作り直す必要がなくなる。具体的には、第2間隔保持部57の孔57Aをあける位置を適宜調整すれば良いので、第2摺動部56の位置調整をするための設計(作業)工数を大幅に削減することができる。 Further, the second spacing holding portion 57 is formed of a member different from the second sliding groove portion 513B (accommodation housing 51) and the arc-shaped guide groove portion 12B (exit wall 12), whereby the second sliding portion 56 is formed. When adjusting the position, it is not necessary to remake the accommodation housing 51 and the exit wall 12. Specifically, since the position of the hole 57A of the second spacing holding portion 57 may be appropriately adjusted, the design (work) man-hours for adjusting the position of the second sliding portion 56 can be significantly reduced. can.
 また、第2間隔保持部57が平板部材で構成されているので、孔57Aの位置を調節しやすく、ひいては上記の設計工数を大幅に削減することができる。 Further, since the second spacing holding portion 57 is made of a flat plate member, the position of the hole 57A can be easily adjusted, and the above-mentioned design man-hours can be significantly reduced.
 また、本実施の形態では、第2摺動溝部513Bおよび円弧状ガイド溝部12Bが円弧状に延在して構成されているので、複数の第2摺動部56を一括で収容可能となっている。そのため、溝部内で第2摺動部の位置を規定するような構成と比較して、各第2摺動部56を溝部内に配置しやすく、第2間隔保持部57により各第2摺動部56の間隔を調整しやすくすることができる。 Further, in the present embodiment, since the second sliding groove portion 513B and the arc-shaped guide groove portion 12B are configured to extend in an arc shape, a plurality of second sliding portions 56 can be accommodated at once. There is. Therefore, it is easier to arrange each second sliding portion 56 in the groove as compared with a configuration in which the position of the second sliding portion is defined in the groove, and each second sliding portion is easily arranged by the second spacing holding portion 57. The spacing between the portions 56 can be easily adjusted.
 また、第2間隔保持部57が平板部材で構成されることで、Y方向(反射光L2の出射方向)で幅を取ることがないので、収容筐体51のY方向の大きさを小さくすることができる。 Further, since the second spacing holding portion 57 is composed of a flat plate member, the width is not taken in the Y direction (the emission direction of the reflected light L2), so that the size of the accommodation housing 51 in the Y direction is reduced. be able to.
 また、第2間隔保持部57は、ミラー収容部50および出射壁12に対して非固定状態で配置されている。非固定状態とは、第2間隔保持部57が、ネジ等の止着部材で、どの部位にも固定されておらず、また、どの部位にも接着、溶着等をされていない状態のことを言う。 Further, the second spacing holding portion 57 is arranged in a non-fixed state with respect to the mirror accommodating portion 50 and the exit wall 12. The non-fixed state means that the second spacing holding portion 57 is a fastening member such as a screw and is not fixed to any part, and is not adhered or welded to any part. To tell.
 このため、第2摺動部56とミラー収容部50との位置関係がずれるような力が発生した場合、第2摺動部56が第2間隔保持部57の孔57Aの縁を押して、第2間隔保持部57も第2摺動部56の移動に追従する。 Therefore, when a force is generated that causes the positional relationship between the second sliding portion 56 and the mirror accommodating portion 50 to shift, the second sliding portion 56 pushes the edge of the hole 57A of the second spacing holding portion 57, and the second sliding portion 56 pushes the edge of the hole 57A. The two-spacing holding portion 57 also follows the movement of the second sliding portion 56.
 これにより、ミラー収容部50と出射壁12との間で第2間隔保持部57の位置が安定するため、ミラー収容部50の回転の際に各第2摺動部56がバランスを取りやすい位置に移動しやすくなる。また、第2間隔保持部57は回転方向にも移動するので、各第2摺動部56の間隔が変動しなくなり、ミラー収容部50の回転を安定化させることができる。 As a result, the position of the second spacing holding portion 57 is stabilized between the mirror accommodating portion 50 and the exit wall 12, so that each second sliding portion 56 is easily balanced when the mirror accommodating portion 50 rotates. It becomes easier to move to. Further, since the second spacing holding portion 57 also moves in the rotation direction, the spacing between the second sliding portions 56 does not change, and the rotation of the mirror accommodating portion 50 can be stabilized.
 また、本実施の形態では、筐体10の低背化の観点から、第2摺動溝部513Bおよび円弧状ガイド溝部12BがZ方向の+側に凸となる円弧状に構成され、円弧が構成する円のZ方向の-側の部分が削られた構成となっている。言い換えると、ミラー収容部50におけるY方向周りの回転中心C1が、ミラー収容部50の重心GよりもZ方向の-側に位置する。そのため、第2摺動溝部513Bおよび円弧状ガイド溝部12Bが円状に形成されていない。 Further, in the present embodiment, from the viewpoint of reducing the height of the housing 10, the second sliding groove portion 513B and the arc-shaped guide groove portion 12B are configured in an arc shape to be convex on the + side in the Z direction, and the arc is formed. The part on the-side of the Z-direction of the circle is cut off. In other words, the rotation center C1 around the Y direction in the mirror accommodating portion 50 is located on the − side in the Z direction with respect to the center of gravity G of the mirror accommodating portion 50. Therefore, the second sliding groove portion 513B and the arc-shaped guide groove portion 12B are not formed in a circular shape.
 そのため、各第2摺動部56の間隔を比較的小さくせざるを得なくなる。第2摺動溝部を円状に構成できる場合、3つの第2摺動部56の間隔を120度とすることができ、各第2摺動部56の配置バランスを取りやすいので、ミラー収容部50の回転を安定化させることが可能となる。 Therefore, the distance between the second sliding portions 56 has to be made relatively small. When the second sliding groove portion can be configured in a circular shape, the distance between the three second sliding portions 56 can be set to 120 degrees, and it is easy to balance the arrangement of each second sliding portion 56. It is possible to stabilize the rotation of 50.
 それに対し、本実施の形態では、各第2摺動部56の間隔が比較的小さくなりやすい構成であるので、回転中心C1に対して各第2摺動部56が、例えばZ方向の+側に片寄りやすくなり、回転中心C1に対してZ方向の-側に第2摺動部56がない状態となる。つまり、本実施の形態では、第2摺動部56の配置バランスを取りにくい構成となっている。 On the other hand, in the present embodiment, the distance between the second sliding portions 56 tends to be relatively small, so that the second sliding portions 56 are, for example, on the + side in the Z direction with respect to the rotation center C1. The second sliding portion 56 is not provided on the − side in the Z direction with respect to the rotation center C1. That is, in the present embodiment, it is difficult to balance the arrangement of the second sliding portion 56.
 しかし、本実施の形態では、第2間隔保持部57により、各第2摺動部56の位置関係がずれることがなくなる。そのため、第2摺動部56の配置バランスを取りにくい構成であっても、ミラー収容部50の回転を安定化させることができる。その結果、ミラー収容部50(収容筐体51)の低背化を実現することができる。 However, in the present embodiment, the second spacing holding portion 57 prevents the positional relationship of each second sliding portion 56 from shifting. Therefore, the rotation of the mirror accommodating portion 50 can be stabilized even if the arrangement of the second sliding portion 56 is difficult to balance. As a result, it is possible to reduce the height of the mirror accommodating portion 50 (accommodation housing 51).
 また、本実施の形態では、上述の付勢部33がミラー収容部50をY方向の+側(出射壁12側)に向けて付勢する構成となっている。そのため、付勢部33の付勢力によって、第2摺動部56が円弧状ガイド溝部12Bに押し付けられるので、各第2摺動部56の配置バランスを維持しやすくなり、ひいてはミラー収容部50の回転を安定させることができる。 Further, in the present embodiment, the above-mentioned urging unit 33 urges the mirror accommodating unit 50 toward the + side (exit wall 12 side) in the Y direction. Therefore, the second sliding portion 56 is pressed against the arcuate guide groove portion 12B by the urging force of the urging portion 33, so that it becomes easier to maintain the arrangement balance of each second sliding portion 56, and eventually the mirror accommodating portion 50. The rotation can be stabilized.
 また、上記したように、第2間隔保持部57が第2摺動部56の移動に追従するので、第2摺動部56の間隔を保持しながら、ミラー収容部50の回転位置に応じて、各第2摺動部56同士がバランスをとりやすい位置に自由に移動することができる。その結果、ミラー収容部50の回転を安定化させることができる。 Further, as described above, since the second gap holding portion 57 follows the movement of the second sliding portion 56, the distance between the second sliding portions 56 is maintained and the mirror accommodating portion 50 is rotated according to the rotation position. , Each of the second sliding portions 56 can freely move to a position where it is easy to balance each other. As a result, the rotation of the mirror accommodating portion 50 can be stabilized.
 また、第2摺動溝部513BがY方向の-側に向かうほど先細りとなる形状であり、かつ、円弧状ガイド溝部12BがY方向の+側に向かうほど先細りとなる形状であるので、各溝部において、第2摺動部56を2点で支持することができる。その結果、第2摺動部56の位置を各溝部内で安定させやすくすることができる。 Further, since the second sliding groove portion 513B has a shape that tapers toward the − side in the Y direction and the arcuate guide groove portion 12B has a shape that tapers toward the + side in the Y direction, each groove portion has a shape that tapers. The second sliding portion 56 can be supported at two points. As a result, the position of the second sliding portion 56 can be easily stabilized in each groove portion.
 次に、ミラー保持部60について説明する。図17に示すように、ミラー保持部60は、ミラー素子部61を保持する部分であり、ミラー収容部50に対して着脱可能に収容される。ミラー保持部60は、ミラー収容部50内でミラーガイド部511に配置され、ミラーガイド部511上をスライド移動可能に構成されている。ミラー保持部60は、本発明の「光学素子保持部」に対応する。 Next, the mirror holding portion 60 will be described. As shown in FIG. 17, the mirror holding portion 60 is a portion that holds the mirror element portion 61, and is detachably housed in the mirror accommodating portion 50. The mirror holding portion 60 is arranged in the mirror guide portion 511 within the mirror accommodating portion 50, and is configured to be slidable on the mirror guide portion 511. The mirror holding portion 60 corresponds to the "optical element holding portion" of the present invention.
 ミラーガイド部511には、上述した通り、円弧状の回転ガイド溝部511Aが設けられており、ミラー保持部60は、回転ガイド溝部511A上をスライド移動することで、X方向に沿う回転軸(第2回転軸)を中心に回転可能に構成されている。 As described above, the mirror guide portion 511 is provided with an arc-shaped rotation guide groove portion 511A, and the mirror holding portion 60 slides on the rotation guide groove portion 511A to move the rotation axis along the X direction (the first). It is configured to be rotatable around the two rotation axes).
 図25および図26に示すように、ミラー保持部60は、ミラー素子部61と、保持筐体62と、第3摺動部63と、保持接触部64とを有する。 As shown in FIGS. 25 and 26, the mirror holding portion 60 includes a mirror element portion 61, a holding housing 62, a third sliding portion 63, and a holding contact portion 64.
 ミラー素子部61は、入射光L1を反射可能なミラー素子(光学素子)を含んでおり、略矩形状に構成されている。回転ガイド溝部511Aは、Z方向の-側およびY方向の-側に向かう斜め方向に凸となる円弧形状であるので、ミラー保持部60は、回転ガイド溝部511A上に配置されることで、Z方向およびY方向に対して傾斜して配置される(図28等参照)。 The mirror element unit 61 includes a mirror element (optical element) capable of reflecting the incident light L1 and is configured in a substantially rectangular shape. Since the rotation guide groove portion 511A has an arc shape that is convex in the diagonal direction toward the-side in the Z direction and the-side in the Y direction, the mirror holding portion 60 is arranged on the rotation guide groove portion 511A to form a Z. It is arranged at an angle with respect to the direction and the Y direction (see FIG. 28 and the like).
 つまり、ミラー素子部61は、入射光L1を、入射光L1に沿う方向(Z方向)とは異なる方向(Y方向)における一方(+側)に向かって進むように屈曲させることが可能に配置されている。ミラー素子部61は、本発明の「光学素子部」に対応する。 That is, the mirror element unit 61 is arranged so that the incident light L1 can be bent so as to proceed toward one side (+ side) in a direction (Y direction) different from the direction (Z direction) along the incident light L1. Has been done. The mirror element unit 61 corresponds to the "optical element unit" of the present invention.
 図25に示すように、保持筐体62は、ミラー素子部61を保持してミラーガイド部511をスライド移動する部分であり、本体部621と、マグネット保持部622とを有する。 As shown in FIG. 25, the holding housing 62 is a portion that holds the mirror element portion 61 and slides the mirror guide portion 511, and has a main body portion 621 and a magnet holding portion 622.
 本体部621は、ミラー素子部61を固定する部分であり、ミラー素子部61を固定可能な固定面621Aを有する。本体部621は、固定面621AがZ方向の+側を向くようにミラーガイド部511に配置される。ミラー素子部61は、固定面621Aに例えば接着剤等で接着固定される。なお、ミラー素子部61は、本体部621にどのように固定されていても良い。 The main body portion 621 is a portion for fixing the mirror element portion 61, and has a fixed surface 621A to which the mirror element portion 61 can be fixed. The main body portion 621 is arranged on the mirror guide portion 511 so that the fixed surface 621A faces the + side in the Z direction. The mirror element portion 61 is adhesively fixed to the fixing surface 621A with, for example, an adhesive. The mirror element portion 61 may be fixed to the main body portion 621 in any way.
 図26に示すように、本体部621におけるZ方向の-側を向く面には、第3摺動溝部621Bが設けられる。第3摺動溝部621Bは、上述の回転ガイド溝部511Aに沿って配置可能なように、Z方向の-側に凸となる円弧状に構成されている。第3摺動溝部621Bは、ミラーガイド部511の回転ガイド溝部511A(ガイド面)よりも短い弧長を有し、回転ガイド溝部511Aにガイドされる被ガイド面となっている。 As shown in FIG. 26, a third sliding groove portion 621B is provided on the surface of the main body portion 621 facing the − side in the Z direction. The third sliding groove portion 621B is configured in an arc shape that is convex on the − side in the Z direction so that it can be arranged along the rotation guide groove portion 511A described above. The third sliding groove portion 621B has an arc length shorter than that of the rotation guide groove portion 511A (guide surface) of the mirror guide portion 511, and is a guided surface guided by the rotation guide groove portion 511A.
 第3摺動溝部621Bは、本体部621におけるX方向の両端部のそれぞれに設けられ、回転ガイド溝部511AとZ方向で向かい合う位置に設けられる(図27参照)。第3摺動溝部621Bは、底(Z方向の+側)に向かうほど先細りとなるような溝形状を有する。 The third sliding groove portion 621B is provided at both ends of the main body portion 621 in the X direction, and is provided at a position facing the rotation guide groove portion 511A in the Z direction (see FIG. 27). The third sliding groove portion 621B has a groove shape that tapers toward the bottom (+ side in the Z direction).
 第3摺動部63は、回転ガイド溝部511Aと第3摺動溝部621Bとの間に介在する球状部材である。第3摺動部63は、X方向の両端部のそれぞれで3つずつ設けられている。X方向における片側(+側または-側)の3つの第3摺動部63は、第3摺動溝部621Bの溝形状に沿って並んで配置される。 The third sliding portion 63 is a spherical member interposed between the rotation guide groove portion 511A and the third sliding groove portion 621B. Three third sliding portions 63 are provided at both ends in the X direction. The three third sliding portions 63 on one side (+ side or-side) in the X direction are arranged side by side along the groove shape of the third sliding groove portion 621B.
 このように、回転ガイド溝部511Aと、第3摺動溝部621Bとの間を介在する第3摺動部63が球状部材で構成されるので、ミラー保持部60がX方向に沿う回転軸を中心に回転した際、回転ガイド溝部511Aと第3摺動溝部621Bとの間を第3摺動部63が転がりながら摺動する(図27参照)。これにより、ミラー保持部60のX方向に沿う回転軸を中心とした回転をスムーズにすることができる。 As described above, since the third sliding portion 63 interposed between the rotation guide groove portion 511A and the third sliding groove portion 621B is composed of a spherical member, the mirror holding portion 60 is centered on the rotation axis along the X direction. The third sliding portion 63 slides while rolling between the rotation guide groove portion 511A and the third sliding groove portion 621B (see FIG. 27). As a result, the rotation of the mirror holding portion 60 about the rotation axis along the X direction can be smoothed.
 また、本体部621におけるZ方向の-側を向く面には、保持接触部64が取り付けられる。保持接触部64は、X方向の両端部の第3摺動溝部621Bの間に設けられ、上述のミラーガイド部511における共振部511Bと接触可能な位置に配置される(図17参照)。保持接触部64は、振動する共振部511Bと接触することでミラー保持部60を回転駆動させる予圧をミラー保持部60に付与する。 Further, the holding contact portion 64 is attached to the surface of the main body portion 621 facing the negative side in the Z direction. The holding contact portion 64 is provided between the third sliding groove portions 621B at both ends in the X direction, and is arranged at a position capable of contacting the resonance portion 511B in the mirror guide portion 511 described above (see FIG. 17). The holding contact portion 64 applies a preload to the mirror holding portion 60 to rotationally drive the mirror holding portion 60 by coming into contact with the vibrating resonance portion 511B.
 つまり、共振部511Bおよび保持接触部64は、ミラー保持部60のX方向周りの回転駆動、つまり、ミラー保持部60をミラーガイド部511上で移動するように駆動する駆動部(第2駆動部)となる超音波モータを構成する。なお、第2駆動部としては、VCM等、超音波モータ以外のものでも良い。 That is, the resonance portion 511B and the holding contact portion 64 are rotationally driven around the X direction of the mirror holding portion 60, that is, a driving unit (second driving unit) that drives the mirror holding portion 60 to move on the mirror guide portion 511. ) Consists of an ultrasonic motor. The second drive unit may be something other than an ultrasonic motor, such as a VCM.
 また、図28に示すように、本体部621は、ミラー保持部60がZ方向の+側へ最も回転した際、Z方向の+側の端部が、上述の規制カバー部52と対向し、かつ、第1規制壁521Aに接触しない程度の位置まで移動する(破線参照)。第1規制壁521Aが存在することにより、本体部621が過剰に移動した場合や、また、Z方向の+側へ移動させる外力が付与された場合でも、本体部621のZ方向の+側への移動を規制することができる。 Further, as shown in FIG. 28, in the main body portion 621, when the mirror holding portion 60 is most rotated to the + side in the Z direction, the end portion on the + side in the Z direction faces the above-mentioned regulation cover portion 52. Moreover, it moves to a position where it does not come into contact with the first regulation wall 521A (see the broken line). Due to the presence of the first regulation wall 521A, even when the main body portion 621 moves excessively or when an external force for moving the main body portion 621 is applied to the + side in the Z direction, the main body portion 621 moves to the + side in the Z direction. Can regulate the movement of.
 図25および図26に示すように、マグネット保持部622は、本体部621のX方向の両端部に設けられ、当該両端部のそれぞれから、Z方向の+側、かつ、Y方向の+側に突出している。 As shown in FIGS. 25 and 26, the magnet holding portions 622 are provided at both ends of the main body portion 621 in the X direction, and are located on the + side in the Z direction and the + side in the Y direction from each of the both ends. It stands out.
 図28および図29に示すように、マグネット保持部622は、上述の規制カバー部52の第2規制壁522AとZ方向で対向する位置に配置されている。マグネット保持部622のZ方向の+側への突出量は、第2規制壁522Aと接触しない程度である。第2規制壁522Aが存在することにより、本体部621に、Z方向の+側へ移動させる外力が付与されても、本体部621のZ方向の+側への移動を規制することができる。 As shown in FIGS. 28 and 29, the magnet holding portion 622 is arranged at a position facing the second regulating wall 522A of the above-mentioned regulation cover portion 52 in the Z direction. The amount of protrusion of the magnet holding portion 622 to the + side in the Z direction is such that it does not come into contact with the second regulation wall 522A. Due to the presence of the second regulation wall 522A, even if an external force for moving the main body portion 621 to the + side in the Z direction is applied, the movement of the main body portion 621 to the + side in the Z direction can be restricted.
 また、図29に示すように、マグネット保持部622は、上述の側壁514における規制部514AとY方向で対向しており、ミラー保持部60がY方向の+側へ最も回転した際、Y方向の+側の端部が、規制部514Aと接触しない程度の位置まで移動する(破線参照)。規制部514Aが存在することにより、ミラー保持部60が過剰に移動した場合や、Y方向の+側へ移動させる外力が付与された場合でも、ミラー保持部60のY方向の+側への移動を規制することができる。 Further, as shown in FIG. 29, the magnet holding portion 622 faces the restricting portion 514A in the above-mentioned side wall 514 in the Y direction, and when the mirror holding portion 60 is most rotated to the + side in the Y direction, the Y direction is reached. The + side end of the magnet moves to a position where it does not come into contact with the restricting portion 514A (see the broken line). Due to the presence of the restricting portion 514A, the mirror holding portion 60 moves to the + side in the Y direction even when the mirror holding portion 60 moves excessively or when an external force for moving the mirror holding portion 60 to the + side in the Y direction is applied. Can be regulated.
 図25および図26に示すように、マグネット保持部622には、マグネット部623が設けられている。マグネット部623は、Y方向において隣接して配置された第1極623Aおよび第2極623Bを有する。第1極623Aは、S極の磁石であり、第2極623Bは、N極の磁石である。 As shown in FIGS. 25 and 26, the magnet holding portion 622 is provided with a magnet portion 623. The magnet portion 623 has a first pole 623A and a second pole 623B arranged adjacent to each other in the Y direction. The first pole 623A is an S pole magnet, and the second pole 623B is an N pole magnet.
 図30に示すように、マグネット保持部622におけるマグネット部623を保持する部分は、上述の収容筐体51におけるヨーク配置部514BにZ方向で対向する位置に設けられている。マグネット保持部622は、Z方向の-側の面が、ヨーク配置部514B(ヨーク部515)に沿う形状を有する。具体的には、マグネット保持部622は、ミラー保持部60の移動に伴い、ヨーク部515の第1面515Aに沿って移動可能で、かつ、第1面515A(回転ガイド溝部511A)と同じ曲率を有する第2面623Cを有する。 As shown in FIG. 30, the portion of the magnet holding portion 622 that holds the magnet portion 623 is provided at a position facing the yoke arranging portion 514B of the above-mentioned accommodating housing 51 in the Z direction. The magnet holding portion 622 has a shape in which the surface on the − side in the Z direction follows the yoke arrangement portion 514B (yoke portion 515). Specifically, the magnet holding portion 622 can move along the first surface 515A of the yoke portion 515 with the movement of the mirror holding portion 60, and has the same curvature as the first surface 515A (rotation guide groove portion 511A). It has a second surface 623C having.
 マグネット保持部622がマグネット部623を保持することにより、マグネット部623は、ヨーク配置部514Bにおけるヨーク部515と対向して配置されている。 By the magnet holding portion 622 holding the magnet portion 623, the magnet portion 623 is arranged so as to face the yoke portion 515 in the yoke arranging portion 514B.
 これにより、マグネット部623とヨーク部515とが磁気的に引き付け合う。つまり、マグネット部623およびヨーク部515は、ミラー保持部60を収容筐体51側へ磁気的に引き付ける与圧を発生させる。 As a result, the magnet portion 623 and the yoke portion 515 are magnetically attracted to each other. That is, the magnet portion 623 and the yoke portion 515 generate a pressurization that magnetically attracts the mirror holding portion 60 to the accommodation housing 51 side.
 その結果、ミラー保持部60は、回転駆動する際や、外力の付与が発生した際でも、収容筐体51に引き付けられた状態となるので、筐体10内でミラー素子部61を確実に保持することができる。 As a result, the mirror holding portion 60 is in a state of being attracted to the accommodating housing 51 even when it is rotationally driven or when an external force is applied, so that the mirror element unit 61 is reliably held in the housing 10. can do.
 ところで、図28および図29に示すように、本実施の形態では、筐体10の簡素化および低背化の観点から、回転ガイド溝部511Aおよび第3摺動溝部621Bが構成する湾曲形状は、ミラー保持部60のY方向の移動量が比較的多く、かつ、ミラー保持部60のZ方向の移動量が比較的少なくなるように設定されている。そのため、本実施の形態に係るミラー保持部60の回転軸における回転中心C2は、収容筐体51の外側に位置する。 By the way, as shown in FIGS. 28 and 29, in the present embodiment, from the viewpoint of simplifying and reducing the height of the housing 10, the curved shape formed by the rotary guide groove portion 511A and the third sliding groove portion 621B has a curved shape. The amount of movement of the mirror holding portion 60 in the Y direction is relatively large, and the amount of movement of the mirror holding portion 60 in the Z direction is set to be relatively small. Therefore, the rotation center C2 on the rotation axis of the mirror holding portion 60 according to the present embodiment is located outside the accommodation housing 51.
 このようにするため、ミラー保持部60は、収容筐体51に固定点を有さない状態で配置される、または、比較的簡素な保持点や係合点を有する状態で配置されることとなる。本実施の形態では、ミラー保持部60は、収容筐体51に固定点を有さない状態で配置されている。 In order to do so, the mirror holding portion 60 is arranged in a state where the accommodating housing 51 does not have a fixed point, or is arranged in a state where it has a relatively simple holding point and an engaging point. .. In the present embodiment, the mirror holding portion 60 is arranged in a state where the accommodating housing 51 does not have a fixed point.
 つまり、筐体10を簡素化および低背化していくと、ミラー保持部60の移動機構を簡素化せざるを得なくなるため、ミラー保持部60(ミラー素子部61)の保持部分が脆弱になりやすく、ひいてはミラー保持部60が収容筐体51から外れやすくなる。 That is, if the housing 10 is simplified and lowered in height, the moving mechanism of the mirror holding portion 60 has to be simplified, so that the holding portion of the mirror holding portion 60 (mirror element portion 61) becomes fragile. It is easy, and by extension, the mirror holding portion 60 is easy to come off from the accommodating housing 51.
 本実施の形態では、マグネット部623とヨーク部515とが磁気的に引き付け合うことにより、ミラー保持部60を筐体10内に確実に保持させることが可能となる。すなわち、本実施の形態では、ミラー保持部60の保持部分が脆弱であっても、ミラー保持部60を収容筐体51内に確実に保持させることができる。そして、これにより、本実施の形態では、筐体10を簡素化および低背化しやすくすることができる。 In the present embodiment, the magnet portion 623 and the yoke portion 515 are magnetically attracted to each other, so that the mirror holding portion 60 can be reliably held in the housing 10. That is, in the present embodiment, even if the holding portion of the mirror holding portion 60 is fragile, the mirror holding portion 60 can be reliably held in the accommodating housing 51. As a result, in the present embodiment, the housing 10 can be easily simplified and lowered in height.
 また、本実施の形態では、マグネット部623とヨーク部515との対向部分で、磁気的に引き付け合う与圧が発生するため、回転ガイド溝部511Aと第3摺動溝部621Bとの対向部分のみで与圧を発生させることができる。つまり、マグネット部623およびヨーク部515は、ミラー保持部60の移動に伴って変位する、回転ガイド溝部511Aと第3摺動溝部621Bとの対向位置において、回転ガイド溝部511Aの法線方向の外側に向かって与圧を発生させることができる。 Further, in the present embodiment, since a pressurization that magnetically attracts each other is generated at the facing portion between the magnet portion 623 and the yoke portion 515, only the facing portion between the rotation guide groove portion 511A and the third sliding groove portion 621B is used. Pressurization can be generated. That is, the magnet portion 623 and the yoke portion 515 are displaced outside the rotation guide groove portion 511A in the normal direction at the positions facing the rotation guide groove portion 511A and the third sliding groove portion 621B, which are displaced with the movement of the mirror holding portion 60. Pressurization can be generated toward.
 そのため、本実施の形態では、付勢部材のような常時付勢し続けるような部品を設けることなく、簡易な構成とすることができるとともに、ミラー保持部60を収容筐体51内に確実に保持させることができる。 Therefore, in the present embodiment, it is possible to have a simple configuration without providing a component such as an urging member that constantly urges the mirror, and the mirror holding portion 60 is surely housed in the accommodating housing 51. Can be retained.
 また、マグネット部623がヨーク部515の第1面515Aに沿ってスライド移動するため、ミラー保持部60が移動しても、マグネット部623がヨーク部515の第1面515Aに沿ってスムーズに移動することができる。 Further, since the magnet portion 623 slides and moves along the first surface 515A of the yoke portion 515, even if the mirror holding portion 60 moves, the magnet portion 623 moves smoothly along the first surface 515A of the yoke portion 515. can do.
 また、ヨーク部515の第1面515Aと、マグネット部623の第2面623Cとが回転ガイド溝部511Aと同じ曲率を有するので、マグネット部623におけるヨーク部515上の移動をさらにスムーズにすることができる。 Further, since the first surface 515A of the yoke portion 515 and the second surface 623C of the magnet portion 623 have the same curvature as the rotation guide groove portion 511A, the movement of the magnet portion 623 on the yoke portion 515 can be further smoothed. can.
 また、マグネット保持部622は、収容筐体51の一対の側壁514に沿って配置されている。X方向の+側の側壁514には、上述の位置検出孔514Cが形成されており、位置検出孔514Cに対応する位置には、上述の位置検出部532Aが設けられている。 Further, the magnet holding portion 622 is arranged along the pair of side walls 514 of the accommodating housing 51. The above-mentioned position detection hole 514C is formed on the side wall 514 on the + side in the X direction, and the above-mentioned position detection unit 532A is provided at a position corresponding to the position detection hole 514C.
 図30に示すように、位置検出部532Aは、マグネット部623の磁力を検出可能な位置に配置されており、ミラー保持部60の移動に基づくマグネット保持部622のマグネット部623の磁気的な位置の変化を検出する。つまり、位置検出部532Aは、ミラー保持部60の位置を検出する。 As shown in FIG. 30, the position detecting unit 532A is arranged at a position where the magnetic force of the magnet unit 623 can be detected, and the magnetic position of the magnet unit 623 of the magnet holding unit 622 based on the movement of the mirror holding unit 60. Detects changes in. That is, the position detection unit 532A detects the position of the mirror holding unit 60.
 その結果、ミラー保持部60の位置制御を精度良く行うことができる。また、ヨーク部515との関係で、ミラー保持部60と収容筐体51とを引き付け合うためのマグネット部623を位置検出用のマグネットにも用いることができる。その結果、位置検出用のマグネットを別途設ける必要がなくなるので、部品点数を削減することができるとともに、構成をさらに簡素化することができる。 As a result, the position of the mirror holding unit 60 can be controlled with high accuracy. Further, in relation to the yoke portion 515, the magnet portion 623 for attracting the mirror holding portion 60 and the accommodation housing 51 can be used as a magnet for position detection. As a result, since it is not necessary to separately provide a magnet for position detection, the number of parts can be reduced and the configuration can be further simplified.
 次に、給電経路部70について説明する。図31に示すように、給電経路部70は、基板部20とミラー収容部50とを電気的に接続し、基板部20とミラー収容部50との間の給電経路を構成する。 Next, the power supply path unit 70 will be described. As shown in FIG. 31, the power supply path unit 70 electrically connects the board unit 20 and the mirror accommodating unit 50 to form a power supply path between the substrate unit 20 and the mirror accommodating unit 50.
 給電経路部70は、例えば、ミラー収容部50における共振部511Bと位置検出部532Aとの給電に用いられ、正極側と負極側とでそれぞれ3つの、合計6つ設けられている。正極側の、3つの給電経路部70は、例えば、ミラー収容部50よりもX方向の-側に配置され、負極側の、3つの給電経路部70は、例えば、ミラー収容部50よりもX方向の+側に配置される。つまり、給電経路部70は、Z方向およびY方向のそれぞれに直交するX方向におけるミラー収容部50の両端側にそれぞれ設けられている。 The power supply path unit 70 is used, for example, for power supply between the resonance unit 511B and the position detection unit 532A in the mirror accommodating unit 50, and is provided with three on the positive electrode side and three on the negative electrode side, for a total of six. The three feeding path portions 70 on the positive electrode side are arranged on the negative side in the X direction with respect to the mirror accommodating portion 50, for example, and the three feeding path portions 70 on the negative electrode side are X with respect to, for example, the mirror accommodating portion 50. It is placed on the + side of the direction. That is, the feeding path portions 70 are provided on both ends of the mirror accommodating portion 50 in the X direction orthogonal to each of the Z direction and the Y direction.
 なお、図31等では、X方向の-側の給電経路部70のみを示している。X方向の+側の給電経路部70は、X方向の-側の給電経路部70と略同一の形状を有するため、説明を省略する。また、端子12Cは、出射壁12にインサートされているが、図31等では、出射壁12の図示は省略し、端子12Cのみを示している。 Note that, in FIG. 31 and the like, only the feeding path portion 70 on the − side in the X direction is shown. Since the power feeding path 70 on the + side in the X direction has substantially the same shape as the feeding path 70 on the − side in the X direction, the description thereof will be omitted. Further, although the terminal 12C is inserted into the emission wall 12, the illustration of the emission wall 12 is omitted in FIG. 31 and the like, and only the terminal 12C is shown.
 図31および図32に示すように、給電経路部70は、筐体10において、上述の基板部20の入出力端子21Aに接続される端子12Cが位置するY方向の+側の端部から、収容側基板部53の第1給電端子531Aおよびミラー収容部50の経路保持部512Bが位置するY方向の-側の端部まで延びている。つまり、給電経路部70は、Y方向におけるミラー収容部50の両端部にわたって延びており、Y方向で離間して配置された端子12C(基板部20側の端子)と、第1給電端子531A(ミラー収容部50側の端子)とを接続するように延在する。 As shown in FIGS. 31 and 32, the power feeding path portion 70 is formed from the + side end portion in the Y direction in which the terminal 12C connected to the input / output terminal 21A of the above-mentioned board portion 20 is located in the housing 10. The first power supply terminal 531A of the accommodation side board portion 53 and the path holding portion 512B of the mirror accommodation portion 50 extend to the end on the − side in the Y direction. That is, the power feeding path portion 70 extends over both ends of the mirror accommodating portion 50 in the Y direction, and the terminal 12C (terminal on the substrate portion 20 side) arranged apart in the Y direction and the first feeding terminal 531A ( It extends so as to connect with the terminal on the mirror accommodating portion 50 side).
 給電経路部70は、基板部20の入出力端子21Aに接続された、上述の端子12CからY方向に沿う方向に延びてミラー収容部50の収容側基板部53の第1給電端子531Aに接続される。 The power supply path unit 70 extends from the terminal 12C described above connected to the input / output terminal 21A of the board unit 20 in the direction along the Y direction and is connected to the first power supply terminal 531A of the accommodation side board unit 53 of the mirror accommodation unit 50. Will be done.
 給電経路部70は、バネ部を部分的に含んで構成されている。具体的には、給電経路部70は、第1ワイヤー部71Aと、第1バネ部72Aと、第2ワイヤー部71Bと、第2バネ部72Bと、第3ワイヤー部71Cとで構成されている。 The power supply path portion 70 is configured to partially include a spring portion. Specifically, the power feeding path portion 70 is composed of a first wire portion 71A, a first spring portion 72A, a second wire portion 71B, a second spring portion 72B, and a third wire portion 71C. ..
 第1ワイヤー部71Aおよび第3ワイヤー部71Cは、給電経路部70のY方向の両端部のそれぞれに位置するワイヤー部であり、基板部20またはミラー収容部50の収容側基板部53の入出力部分(端子12Cまたは第1給電端子531A)に接続される。第1ワイヤー部71Aおよび第3ワイヤー部71Cと、入出力部分との接続部分には、ダンパー部材73が設けられる。 The first wire portion 71A and the third wire portion 71C are wire portions located at both ends of the feeding path portion 70 in the Y direction, and are input / output of the substrate portion 20 or the accommodation side substrate portion 53 of the mirror housing portion 50. It is connected to a portion (terminal 12C or first power supply terminal 531A). A damper member 73 is provided at a connection portion between the first wire portion 71A and the third wire portion 71C and the input / output portion.
 第1ワイヤー部71Aは、第1バネ部72Aに接続され、第3ワイヤー部71Cよりも短く構成されている。第3ワイヤー部71Cは、第2バネ部72Bに接続されている。 The first wire portion 71A is connected to the first spring portion 72A and is shorter than the third wire portion 71C. The third wire portion 71C is connected to the second spring portion 72B.
 第2ワイヤー部71Bは、第1バネ部72Aと、第2バネ部72Bとを接続し、第1ワイヤー部71Aおよび第3ワイヤー部71Cよりも長く構成されている。 The second wire portion 71B connects the first spring portion 72A and the second spring portion 72B, and is configured to be longer than the first wire portion 71A and the third wire portion 71C.
 第1バネ部72Aおよび第2バネ部72Bは、コイルバネで構成されたコイル部である。第1バネ部72Aは、第1ワイヤー部71Aと第2ワイヤー部71Bとの間に配置され、第2バネ部72Bは、第2ワイヤー部71Bと第3ワイヤー部71Cとの間に配置されている。第2バネ部72Bは、第1バネ部72Aよりも長く構成されている。 The first spring portion 72A and the second spring portion 72B are coil portions composed of coil springs. The first spring portion 72A is arranged between the first wire portion 71A and the second wire portion 71B, and the second spring portion 72B is arranged between the second wire portion 71B and the third wire portion 71C. There is. The second spring portion 72B is configured to be longer than the first spring portion 72A.
 X方向の片側(+側または-側)の3つの給電経路部70は、Z方向で並んで配置されており、互いに干渉しないように配置されている。具体的には、3つの給電経路部70のうち、Z方向で隣り合う2つの給電経路部70の各バネ部72A,72Bが、Y方向の位置が互いに異なるように配置されている。 The three power feeding path portions 70 on one side (+ side or-side) in the X direction are arranged side by side in the Z direction so as not to interfere with each other. Specifically, of the three feeding path portions 70, the spring portions 72A and 72B of the two feeding path portions 70 adjacent to each other in the Z direction are arranged so that the positions in the Y direction are different from each other.
 つまり、例えば、Z方向の最も+側、および、最も-側の給電経路部70は、基板部20の端子12Cに第1ワイヤー部71Aが接続され、ミラー収容部50の経路保持部512Bに第3ワイヤー部71Cが接続されている。またZ方向の真ん中に位置する給電経路部70は、基板部20の端子12Cに第3ワイヤー部71Cが接続され、ミラー収容部50の経路保持部512Bに第1ワイヤー部71Aが接続されている。 That is, for example, in the power supply path portion 70 on the most + side and the most-side in the Z direction, the first wire portion 71A is connected to the terminal 12C of the substrate portion 20, and the path holding portion 512B of the mirror accommodating portion 50 is connected to the first wire portion 71A. 3 The wire portion 71C is connected. Further, in the power feeding path portion 70 located in the center of the Z direction, the third wire section 71C is connected to the terminal 12C of the board section 20, and the first wire section 71A is connected to the path holding section 512B of the mirror accommodating section 50. ..
 また、X方向の片側の3つの給電経路部70のY方向の中央部には、位置固定部74が設けられている。位置固定部74は、3つの給電経路部70における互いの位置関係を一定範囲内に維持するためのものである。位置固定部74は、板状に構成されて、各第2ワイヤー部71Bの部分が係合可能に構成されている。 Further, a position fixing portion 74 is provided at the center portion in the Y direction of the three power supply path portions 70 on one side in the X direction. The position fixing portion 74 is for maintaining the positional relationship between the three feeding path portions 70 within a certain range. The position fixing portion 74 is configured in a plate shape, and the portions of the second wire portions 71B are configured to be engageable with each other.
 また、Z方向の最も+側、および、最も-側の給電経路部70においては、位置固定部74との係合部分にダンパー部材75が設けられている。また、Z方向の真ん中の給電経路部70においては、位置固定部74との係合部分がフリーな状態となっている。具体的には、位置固定部74には、Z方向の真ん中の給電経路部70に対応する部分74Aが切り欠かれており、当該部分74AにZ方向の真ん中の給電経路部70が通されている。 Further, in the feeding path portion 70 on the most + side and the most-side in the Z direction, a damper member 75 is provided at an engaging portion with the position fixing portion 74. Further, in the feeding path portion 70 in the middle in the Z direction, the engaging portion with the position fixing portion 74 is in a free state. Specifically, the position fixing portion 74 is cut out from the portion 74A corresponding to the feeding path portion 70 in the middle in the Z direction, and the feeding path portion 70 in the middle in the Z direction is passed through the portion 74A. There is.
 ところで、図33および図34に示すように、ミラー収容部50がY方向周りの回転軸を中心に回転した際、ミラー収容部50の第1給電端子531AがZ方向(移動方向)の+側または-側に移動する。言い換えると、ミラー収容部50は、給電経路部70の接続部分である第1給電端子531Aが、基板部20に対して接近または離反するように移動する。 By the way, as shown in FIGS. 33 and 34, when the mirror accommodating portion 50 rotates about the rotation axis around the Y direction, the first power feeding terminal 531A of the mirror accommodating portion 50 is on the + side in the Z direction (moving direction). Or move to the-side. In other words, the mirror accommodating portion 50 moves so that the first feeding terminal 531A, which is the connecting portion of the feeding path portion 70, approaches or separates from the substrate portion 20.
 例えば、ミラー収容部50が、図33に示す位置から、X方向の-側の端部が持ち上がる側に回転して、X方向の-側の第1給電端子531AがZ方向の+側に移動したとする。なお、ミラー収容部50がX方向の+側の端部が持ち上がる側に回転すると、X方向の-側の第1給電端子531Aは、Z方向の-側に移動する。 For example, the mirror accommodating portion 50 rotates from the position shown in FIG. 33 to the side where the end portion on the-side in the X direction is lifted, and the first power feeding terminal 531A on the-side in the X direction moves to the + side in the Z direction. Suppose you did. When the mirror accommodating portion 50 rotates to the side where the end portion on the + side in the X direction is lifted, the first power feeding terminal 531A on the − side in the X direction moves to the − side in the Z direction.
 そうすると、図34に示すように、第1給電端子531Aが、ミラー収容部50の移動後において、移動前の位置(図33参照)よりもZ方向の+側に位置することとなる。そのため、ミラー収容部50の移動後において(図34参照)、バネ部72A,72Bが、移動前の状態(図33参照)よりも長く延びた状態となる。 Then, as shown in FIG. 34, the first power feeding terminal 531A is located on the + side in the Z direction with respect to the position before the movement (see FIG. 33) after the mirror accommodating portion 50 is moved. Therefore, after the mirror accommodating portion 50 is moved (see FIG. 34), the spring portions 72A and 72B are in a state of being extended longer than the state before the movement (see FIG. 33).
 この場合、例えば基板部とミラー収容部とを板バネを給電経路部として接続していた場合、板バネは反力が比較的強いため、当該反力に起因してミラー収容部の回転を阻害しやすい。 In this case, for example, when the board portion and the mirror accommodating portion are connected by using a leaf spring as a feeding path portion, the leaf spring has a relatively strong reaction force, and the reaction force hinders the rotation of the mirror accommodating portion. It's easy to do.
 それに対し、本実施の形態では、給電経路部70がY方向にわたって延びており、かつ、バネ部72A,72Bがコイルバネで構成されているので、ミラー収容部50の回転に追従してバネ部72A,72Bが伸縮しやすい構成とすることができる。 On the other hand, in the present embodiment, since the feeding path portion 70 extends in the Y direction and the spring portions 72A and 72B are composed of coil springs, the spring portion 72A follows the rotation of the mirror accommodating portion 50. , 72B can be configured to easily expand and contract.
 つまり、バネ部72A,72Bは、比較的反力が低いため、ミラー収容部50の回転に起因する、基板部20とミラー収容部50との、移動前後における位置関係のずれを吸収することができる。その結果、ミラー収容部50の収容側基板部53に給電しつつ、ミラー収容部50の回転をスムーズにすることができる。 That is, since the spring portions 72A and 72B have relatively low reaction forces, it is possible to absorb the displacement of the positional relationship between the substrate portion 20 and the mirror accommodating portion 50 before and after the movement due to the rotation of the mirror accommodating portion 50. can. As a result, the rotation of the mirror accommodating portion 50 can be made smooth while supplying power to the accommodating side substrate portion 53 of the mirror accommodating portion 50.
 ところで、給電経路部70の全てを各バネ部72A,72BをY方向の位置を同じにした構成の場合、例えば、図34に示すように、バネ部72A,72Bが長く延びた状態の位置にミラー収容部50が移動すると、隣り合う2つの給電経路部70が、互いに近づきやすくなるので、互いのバネ部が干渉しやすくなる。 By the way, in the case where all of the power feeding path portions 70 have the spring portions 72A and 72B at the same position in the Y direction, for example, as shown in FIG. 34, the spring portions 72A and 72B are in the positions where they are extended long. When the mirror accommodating portion 50 moves, the two adjacent feeding path portions 70 tend to approach each other, so that the spring portions tend to interfere with each other.
 それに対し、本実施の形態では、3つの給電経路部70のうち、Z方向で隣り合う2つの給電経路部70の各バネ部72A,72BのY方向の位置が互いに異なるので、各バネ部72A,72Bが伸縮に基づいて変形した際に、隣り合う2つの給電経路部70のバネ部同士が干渉することがなくなる。その結果、2つの給電経路部70による給電を正確にすることができる。なお、給電経路部70のバネ部の巻径を縮径させて構成することで、給電経路部70の全体にバネ部を設けることも可能である。この構成では、各給電経路部の間隔を変えることなく、隣り合う2つの給電経路部のバネ部の間隔を、巻径を縮径させない構成と比較して、広げることができるので、バネ部同士の干渉を抑制しつつ、部分的にバネ部を有する構成と比較して、より反力を弱めることができる。 On the other hand, in the present embodiment, of the three power supply path portions 70, the positions of the spring portions 72A and 72B of the two power supply path portions 70 adjacent to each other in the Z direction are different from each other in the Y direction, so that the spring portions 72A are different from each other. When the 72B is deformed based on expansion and contraction, the spring portions of the two adjacent feeding path portions 70 do not interfere with each other. As a result, the power supply by the two power supply path units 70 can be made accurate. It is also possible to provide the spring portion in the entire feeding path portion 70 by reducing the winding diameter of the spring portion of the feeding path portion 70. In this configuration, the distance between the spring parts of two adjacent power supply paths can be widened without changing the distance between the spring parts, as compared with the configuration in which the winding diameter is not reduced. It is possible to further weaken the reaction force as compared with the configuration having a partially spring portion while suppressing the interference of the above.
 また、各給電経路部70を限りなく近く配置することができるので、給電経路部70の配置スペースを削減することができ、ひいてはミラー収容部50の小型化および低背化を図ることができる。 Further, since each power feeding path 70 can be arranged as close as possible, the space for arranging the feeding path 70 can be reduced, and the mirror accommodating portion 50 can be miniaturized and reduced in height.
 また、位置固定部74が設けられることで、3つの給電経路部70のZ方向における位置関係を一定範囲内に維持することができるので、3つの給電経路部70が干渉することをさらに抑制することができる。 Further, by providing the position fixing portion 74, the positional relationship between the three feeding path portions 70 in the Z direction can be maintained within a certain range, so that the interference of the three feeding path portions 70 is further suppressed. be able to.
 また、Z方向の真ん中の給電経路部70は、バネ部の並びが他の2つの給電経路部70とは異なるため、ミラー収容部50が回転した際のバネ部の変形の態様が、他の2つの給電経路部70とは異なる。そのため、他の2つの給電経路部70と同様に、当該給電経路部70を位置固定部74に固定してしまうと、ミラー収容部50の回転による、給電経路部70の動きに影響を与える。 Further, since the arrangement of the spring portions of the power feeding path portion 70 in the middle in the Z direction is different from that of the other two feeding path portions 70, the deformation of the spring portion when the mirror accommodating portion 50 rotates is different. It is different from the two power supply path units 70. Therefore, similarly to the other two feeding path portions 70, if the feeding path section 70 is fixed to the position fixing section 74, the movement of the feeding path section 70 due to the rotation of the mirror accommodating section 50 is affected.
 それに対し、本実施の形態では、Z方向の真ん中の給電経路部70のみが位置固定部74に非固定状態で設けられている。その結果、ミラー収容部50の回転による、当該給電経路部70の動きの影響を、他の2つの給電経路部70に対して与えることを抑制することができる。 On the other hand, in the present embodiment, only the feeding path portion 70 in the middle in the Z direction is provided in the position fixing portion 74 in a non-fixed state. As a result, it is possible to suppress the influence of the movement of the feeding path portion 70 due to the rotation of the mirror accommodating portion 50 on the other two feeding path portions 70.
 なお、上記実施の形態では、付勢部33が、Z方向の+側のアーム部332とZ方向の-側のアーム部332とが同一の形状であるようなZ方向で対称な形状(図10参照)に構成されていたが、本発明はこれに限定されず、Z方向で対称な形状に構成されていなくても良い。 In the above embodiment, the urging portion 33 has a symmetrical shape in the Z direction such that the arm portion 332 on the + side in the Z direction and the arm portion 332 on the-side in the Z direction have the same shape (FIG. 10), but the present invention is not limited to this, and it does not have to be configured to have a symmetrical shape in the Z direction.
 例えば、図35に示すように、付勢部33におけるZ方向の+側のアーム部332Aと、Z方向の-側のアーム部332Bとが異なる形状であっても良い。Z方向の+側のアーム部332Aは、直線部A1と、湾曲部A2とを有する。 For example, as shown in FIG. 35, the arm portion 332A on the + side in the Z direction and the arm portion 332B on the-side in the Z direction in the urging portion 33 may have different shapes. The arm portion 332A on the + side in the Z direction has a straight portion A1 and a curved portion A2.
 直線部A1は、環状部331のZ方向の+側の端部から、X方向における、付勢部33の端部側に向かって延びている。直線部A1の端部は、2つのアーム部332A,332Bの接続部付近まで延びている。 The straight line portion A1 extends from the end portion on the + side of the annular portion 331 in the Z direction toward the end portion side of the urging portion 33 in the X direction. The end of the straight line portion A1 extends to the vicinity of the connecting portion of the two arm portions 332A and 332B.
 湾曲部A2は、直線部A1の、環状部331とは反対側の端部から、Z方向の-側に湾曲して、X方向の環状部331側に向かった後、X方向の環状部331とは反対側に湾曲して接続部333に接続される。 The curved portion A2 is curved from the end portion of the straight portion A1 opposite to the annular portion 331 to the negative side in the Z direction toward the annular portion 331 in the X direction, and then the annular portion 331 in the X direction. It is curved to the opposite side and connected to the connection portion 333.
 Z方向の-側のアーム部332Bは、環状部331のX方向の端部におけるZ方向の+側寄りの部位から、Z方向の-側に湾曲した後、Z方向の+側に向けて湾曲して、接続部333に接続される。 The arm portion 332B on the-side in the Z direction is curved toward the + side in the Z direction from the portion on the + side in the Z direction at the end of the annular portion 331 in the X direction, and then curved toward the + side in the Z direction. Then, it is connected to the connection unit 333.
 このような形状を有することで付勢部33は、ミラー収容部50の回転中心C1よりも、Z方向の+側の部位の付勢力が、当該回転中心C1よりも、Z方向の-側の部位の付勢力よりも大きくなる。 By having such a shape, the urging portion 33 has the urging force of the portion on the + side in the Z direction with respect to the rotation center C1 of the mirror accommodating portion 50 on the-side in the Z direction with respect to the rotation center C1. It becomes larger than the urging force of the part.
 上記実施の形態では、ミラー収容部50の回転中心C1がミラー収容部50の重心GよりもZ方向の-側に位置する構成となっているため、第2摺動溝部513Bおよび円弧状ガイド溝部12Bの円弧を構成する円のZ方向の-側の部分が削られた構成となっている。そのため、ミラー収容部50において、Y方向の-側の端部(キャップ部40の部分)において、回転中心C1よりもZ方向の+側にかかる負荷が、回転中心C1よりもZ方向の-側にかかる負荷よりも大きくなっている。 In the above embodiment, since the rotation center C1 of the mirror accommodating portion 50 is located on the − side in the Z direction with respect to the center of gravity G of the mirror accommodating portion 50, the second sliding groove portion 513B and the arcuate guide groove portion The portion on the-side of the circle forming the arc of 12B in the Z direction is cut off. Therefore, in the mirror accommodating portion 50, the load applied to the + side in the Z direction from the rotation center C1 at the end on the-side in the Y direction (the portion of the cap portion 40) is on the-side in the Z direction from the rotation center C1. It is larger than the load applied to.
 そこで、図35に示す付勢部33を用いることで、回転中心C1よりもZ方向の+側の付勢力を高めることにより、より安定してキャップ部40側で、Y方向の負荷を受けやすくすることができ、ひいてはミラー収容部50の回転を安定化させることができる。 Therefore, by using the urging portion 33 shown in FIG. 35, the urging force on the + side in the Z direction is increased from the rotation center C1, so that the cap portion 40 is more stable and easily receives the load in the Y direction. As a result, the rotation of the mirror accommodating portion 50 can be stabilized.
 また、上記実施の形態では、第1間隔保持部55の孔55Aが、3つの第1摺動部54を配置可能な大きさであったが、本発明はこれに限定されず、例えば、図36に示すように、1つの第1摺動部54のみを配置可能な大きさであっても良い。 Further, in the above embodiment, the hole 55A of the first spacing holding portion 55 has a size capable of arranging the three first sliding portions 54, but the present invention is not limited to this, and the present invention is not limited to this, for example, FIG. As shown in 36, the size may be such that only one first sliding portion 54 can be arranged.
 この第1間隔保持部55の孔55Bは、1つの第1摺動部54と略同等の径であって、1つの第1摺動部54が孔55B内で回転可能な程度の径を有する。 The hole 55B of the first spacing holding portion 55 has a diameter substantially equal to that of one first sliding portion 54, and has a diameter such that one first sliding portion 54 can rotate in the hole 55B. ..
 このような構成とすることで、各第1摺動部54の間隔を等間隔に維持することができる。 With such a configuration, the spacing between the first sliding portions 54 can be maintained at equal intervals.
 また、上記実施の形態では、第1間隔保持部55は、ミラー収容部50に固定されていたが、本発明はこれに限定されず、ミラー収容部50およびキャップ部40に対して非固定状態で配置されていても良い。 Further, in the above embodiment, the first interval holding portion 55 is fixed to the mirror accommodating portion 50, but the present invention is not limited to this, and is not fixed to the mirror accommodating portion 50 and the cap portion 40.
