　　＜レンズ鏡筒４＞
　レンズ鏡筒４は、光軸方向に伸びる円筒状の部材であって、レンズ４ａを含む１以上の光学部材を保持する。レンズ鏡筒４に保持される光学部材には、レンズ４ａの他に、レンズ、スペーサ、口径板、及び光学フィルタなどが含まれる。レンズ４ａを含むレンズは、ガラスまたはプラスチック等の透過性を有する素材で形成され、光軸方向前方からの光を屈折させながら光軸方向後方に透過させる。スペーサは、光軸方向に適度な厚みを有する板状で円環状の部材であり、各レンズの光軸方向の位置を調整する。スペーサは、光軸を含む中心部に開口部を有する。口径板は、通過する光の最外位置を決める。光学フィルタは、所定の波長の光を抑制または遮蔽する。光学フィルタは、例えば、通過する赤外線を抑制する赤外線カットフィルタなどが含まれる。レンズ鏡筒４に保持されるこれらの光学部材の数及び種類は、任意に変更可能である。 <Lens barrel 4>
The lens barrel 4 is a cylindrical member extending in the optical axis direction, and holds one or more optical members including the lens 4a. The optical member held by the lens barrel 4 includes a lens, a spacer, a caliber plate, an optical filter, and the like in addition to the lens 4a. The lens including the lens 4a is made of a transparent material such as glass or plastic, and transmits light from the front in the optical axis direction while refracting light from the front in the optical axis direction. The spacer is a plate-like and annular member having an appropriate thickness in the optical axis direction, and adjusts the position of each lens in the optical axis direction. The spacer has an opening at the center including the optical axis. The aperture plate determines the outermost position of the light passing therethrough. The optical filter suppresses or blocks light having a predetermined wavelength. The optical filter includes, for example, an infrared cut filter that suppresses passing infrared rays. The number and type of these optical members held in the lens barrel 4 can be arbitrarily changed.
　レンズ鏡筒４は、光軸方向後方に配置されたレンズフランジ５とねじ嵌合する。レンズ鏡筒４は、径方向外側にねじ山が形成されており、レンズフランジ５の開口部の径方向内側に形成されたねじ山とねじ嵌合する（図４の「Ｃ」の位置参照）。レンズ鏡筒４は、レンズフランジ５に対して所定方向に回転されることでレンズフランジ５に対して挿入されていく。つまり、レンズ鏡筒４は、レンズフランジ５に対するねじ込み量に応じて、レンズフランジ５との光軸方向の相対位置が変化する。なお、レンズ鏡筒４とレンズフランジ５とは、ねじ嵌合に代えてカム嵌合であっても良い。つまり、レンズ鏡筒４とレンズフランジ５とは螺合している。 The lens barrel 4 is screw-fitted with a lens flange 5 disposed on the rear side in the optical axis direction. The lens barrel 4 is formed with a thread on the radially outer side, and is screw-fitted with a thread formed on the radially inner side of the opening of the lens flange 5 (see the position “C” in FIG. 4). . The lens barrel 4 is inserted into the lens flange 5 by rotating in a predetermined direction with respect to the lens flange 5. That is, the relative position of the lens barrel 4 in the optical axis direction with the lens flange 5 changes according to the screwing amount with respect to the lens flange 5. The lens barrel 4 and the lens flange 5 may be cam-fitted instead of screw-fitting. That is, the lens barrel 4 and the lens flange 5 are screwed together.
　　＜レンズフランジ５＞
　レンズフランジ５は、レンズ鏡筒４の光軸方向後方に配置される。レンズフランジ５は、光軸に垂直な方向に延びる形状の部材である。レンズフランジ５は、光軸を中心とする開口部を有しており、この開口部にレンズ鏡筒４が挿入されることで、レンズ鏡筒４とねじ嵌合により連結されている（図４の「Ｃ」の位置参照）。また、この開口部の、レンズ鏡筒４より光軸方向後方には、第１基板６１に搭載された撮像素子６３が位置する。 <Lens flange 5>
The lens flange 5 is disposed behind the lens barrel 4 in the optical axis direction. The lens flange 5 is a member having a shape extending in a direction perpendicular to the optical axis. The lens flange 5 has an opening centered on the optical axis, and the lens barrel 4 is inserted into this opening to be coupled to the lens barrel 4 by screw fitting (FIG. 4). (Refer to the position of “C”). Further, an imaging element 63 mounted on the first substrate 61 is located behind the lens barrel 4 in the optical axis direction of the opening.
　レンズフランジ５は、フロントケース１及びリアケース８と連結された状態で、光軸に垂直な方向のケース外側に露出する外部連結部を有する。図３及び図４に示されるように、レンズフランジ５の外部連結部には、貫通孔５ａ～５ｆを有する。貫通孔５ａ～５ｆには、撮像装置を取り付ける取り付け対象機器（「外部機器」と称することがある）に連結するための連結具が挿入されることで、外部機器と連結される。外部機器は、例えば車両などである。 The lens flange 5 is connected to the front case 1 and the rear case 8 and has an external connection portion exposed outside the case in a direction perpendicular to the optical axis. As shown in FIG. 3 and FIG. 4, the external connection portion of the lens flange 5 has through holes 5a to 5f. The through holes 5a to 5f are connected to an external device by inserting a connector for connecting to an attachment target device (sometimes referred to as an “external device”) to which the imaging device is attached. The external device is, for example, a vehicle.
　レンズフランジ５の光軸方向後方の面には、第１基板６１の光軸方向前方の面が接する（図４の「Ｂ」の位置参照）。これにより、レンズフランジ５を基準として、第１基板６１の位置と、第１基板６１に搭載された撮像素子６３の位置とが固定される。 The front surface in the optical axis direction of the first substrate 61 is in contact with the rear surface in the optical axis direction of the lens flange 5 (see the position “B” in FIG. 4). As a result, the position of the first substrate 61 and the position of the image sensor 63 mounted on the first substrate 61 are fixed with the lens flange 5 as a reference.
　　＜第１基板６１及び第２基板６２＞
　第１基板６１及び第２基板６２は、撮像素子６３を含む電子部品が搭載されたリジッド基板である。本実施形態では、第１基板６１に撮像素子６３及び電子部品が搭載され、第２基板６２には電子部品が搭載される。第１基板６１と第２基板６２とは、フレキシブル基板に搭載された導線によって、電気的に接続される。撮像素子６３により取得された電気信号は、第１基板６１及び第２基板６２に搭載された電子部品により所定の電気処理または信号処理が施された後、撮像装置の外部に画像データとして出力される。 <First substrate 61 and second substrate 62>
The first substrate 61 and the second substrate 62 are rigid substrates on which electronic components including the image sensor 63 are mounted. In the present embodiment, the image sensor 63 and electronic components are mounted on the first substrate 61, and the electronic components are mounted on the second substrate 62. The 1st board | substrate 61 and the 2nd board | substrate 62 are electrically connected by the conducting wire mounted in the flexible substrate. The electrical signal acquired by the imaging device 63 is output as image data to the outside of the imaging device after being subjected to predetermined electrical processing or signal processing by electronic components mounted on the first substrate 61 and the second substrate 62. The
　第１基板６１の光軸方向前方の面は、レンズフランジ５の光軸方向後方の面に接する。第２基板６２は、光軸方向後方でコネクタ９と連結する。 The front surface of the first substrate 61 in the optical axis direction is in contact with the rear surface of the lens flange 5 in the optical axis direction. The second substrate 62 is connected to the connector 9 at the rear in the optical axis direction.
　撮像素子６３は、照射された光を電気信号に変換する光電変換素子であり、例えばＣ－ＭＯＳセンサやＣＣＤなどであるが、これらに限定されるものではない。また、撮像装置においては、撮像素子６３以外の撮像機能を要する撮像部を採用してもよい。撮像素子は、本発明の「撮像部」の一例である。 The imaging element 63 is a photoelectric conversion element that converts irradiated light into an electrical signal, and is, for example, a C-MOS sensor or a CCD, but is not limited thereto. In the imaging apparatus, an imaging unit that requires an imaging function other than the imaging element 63 may be employed. The imaging device is an example of the “imaging unit” in the present invention.
　　＜コネクタ９＞
　コネクタ９は、リアケース８の光軸方向後方に配置され、連結具１０ｂによってリアケース８と連結される。コネクタ９は、信号線を含んでおり、撮像装置と外部機器とを電気的に接続させる。 <Connector 9>
The connector 9 is disposed behind the rear case 8 in the optical axis direction, and is connected to the rear case 8 by a connector 10b. The connector 9 includes a signal line and electrically connects the imaging device and an external device.
　本実施形態の撮像装置は、上記のように、レンズ鏡筒４と嵌合するレンズフランジ５がケースの外側に露出し、外部機器と連結可能な構成としている。そのため、フロントケース１またはリアケース８などの構成が光軸の位置ずれに影響せず、光軸の位置ずれは、外部機器とレンズフランジ５との連結部、レンズフランジ５と第１基板６１との当接部、及びレンズフランジ５とレンズ鏡筒４との嵌合部で発生しうるだけである。つまり、外部機器と連結可能なレンズフランジ５を基準にして各部材が連結されるため、これらの各部材に含まれる寸法公差の積み上げにより寸法誤差が大きくなることがないため、光軸調整を容易にすることができる。言い換えれば、光軸の位置ずれに影響する部材を比較的少なくすることができるため、光軸の位置ずれの発生を抑制した構成にすることができる。 As described above, the imaging apparatus according to the present embodiment is configured such that the lens flange 5 fitted to the lens barrel 4 is exposed to the outside of the case and can be connected to an external device. Therefore, the configuration of the front case 1 or the rear case 8 does not affect the positional deviation of the optical axis. The positional deviation of the optical axis is caused by the connecting portion between the external device and the lens flange 5, the lens flange 5 and the first substrate 61. And the fitting portion between the lens flange 5 and the lens barrel 4. That is, since each member is connected with reference to the lens flange 5 that can be connected to an external device, the dimensional tolerance included in each member does not increase, so that the dimensional error does not increase, so that the optical axis can be easily adjusted. Can be. In other words, since it is possible to relatively reduce the number of members that affect the positional deviation of the optical axis, a configuration in which the occurrence of the positional deviation of the optical axis is suppressed can be achieved.
　また、本実施形態の撮像装置では、レンズフランジ５と、撮像素子６３を搭載する第１基板６１とが光軸方向に当接することで、レンズフランジ５と第１基板６１との光軸方向の相対位置が固定されている。これによって、第１基板６１とレンズフランジ５との位置ずれを起こりづらい構成とすることができ、より効果的に光軸の位置ずれを抑制することができる。 Further, in the imaging apparatus of the present embodiment, the lens flange 5 and the first substrate 61 on which the imaging element 63 is mounted abut on the optical axis direction, so that the lens flange 5 and the first substrate 61 are in the optical axis direction. The relative position is fixed. Thereby, it can be set as the structure which is hard to produce the position shift of the 1st board | substrate 61 and the lens flange 5, and the position shift of an optical axis can be suppressed more effectively.
　また、本実施形態の撮像装置では、レンズ鏡筒４がレンズフランジ５と螺合しているため、螺合状態を調整することでレンズフランジ５に対するレンズ鏡筒４の位置を調整することで、撮像素子６３とレンズ鏡筒４との光軸方向の位置を調整するピント調整が可能となる。また、レンズ鏡筒４とレンズフランジ５との螺合状態を固定して相互位置を固定することが可能であるため、光軸の位置ずれを抑制可能な構成とすることができる。 Moreover, in the imaging device of this embodiment, since the lens barrel 4 is screwed with the lens flange 5, by adjusting the screwed state, the position of the lens barrel 4 with respect to the lens flange 5 is adjusted. Focus adjustment for adjusting the positions of the image sensor 63 and the lens barrel 4 in the optical axis direction is possible. Further, since the mutual position can be fixed by fixing the screwed state of the lens barrel 4 and the lens flange 5, it is possible to suppress the positional deviation of the optical axis.

The specific description of the embodiment of the present invention has been given above. In the above description, the description is merely an embodiment, and the scope of the present invention is not limited to this embodiment, but is broadly interpreted to the extent that a person skilled in the art can grasp.
　例えば、実施形態で説明したレンズフランジ５と第１基板６１とは、光軸方向に直接接することで相互の位置が固定されていたが、何らかの部材を介して連結されていても良い。ただし、レンズフランジ５と第１基板６１とが直接接する構成とすると、光軸ずれの原因となる部材の増加を抑制できることとなる点で好ましい。 For example, the lens flange 5 and the first substrate 61 described in the embodiment are fixed in mutual position by being in direct contact with each other in the optical axis direction, but may be connected through some member. However, it is preferable that the lens flange 5 and the first substrate 61 are in direct contact with each other because an increase in the number of members that cause the optical axis deviation can be suppressed.
　また、実施形態の撮像装置では、レンズ鏡筒４とレンズフランジ５とが螺合していたが、レンズ鏡筒４とレンズフランジ５とは単に径嵌合する構成としても良い。 Further, in the imaging apparatus of the embodiment, the lens barrel 4 and the lens flange 5 are screwed together, but the lens barrel 4 and the lens flange 5 may be simply fitted with a diameter.
　また、実施形態の撮像装置では、第１基板６１と第２基板６２との２枚の基板を有する構成を例に挙げて説明したが、基板の数は任意に変更しても良い。つまり、撮像素子６３を搭載する基板は１枚であっても良いし、３枚以上であっても良い。 In the imaging apparatus according to the embodiment, the configuration having the two substrates of the first substrate 61 and the second substrate 62 has been described as an example, but the number of substrates may be arbitrarily changed. That is, the number of substrates on which the image sensor 63 is mounted may be one, or three or more.
　また、実施形態では、レンズ鏡筒４とレンズフランジ５とを別構成とする構成例について説明したが、レンズ鏡筒４とレンズフランジ５とは一体的に形成されても良い。なお、本発明でレンズ鏡筒４とレンズフランジ５とが連結されているという場合には、別構成として連結されている構成のほか、一体的に形成されている構成も含む。 In the embodiment, the configuration example in which the lens barrel 4 and the lens flange 5 are separately configured has been described. However, the lens barrel 4 and the lens flange 5 may be integrally formed. In addition, when the lens barrel 4 and the lens flange 5 are connected in the present invention, a configuration in which the lens barrel 4 and the lens flange 5 are integrally formed is included in addition to a configuration in which they are connected as separate components.
　また、実施形態では、フロントケース１とレンズ鏡筒４とを別構成とする構成例について説明したが、フロントケース１とレンズ鏡筒４とは一体的に形成されても良い。 In the embodiment, the configuration example in which the front case 1 and the lens barrel 4 are configured separately has been described. However, the front case 1 and the lens barrel 4 may be integrally formed.
