In particular, the present invention relates to an imaging apparatus that is assembled by adjusting the position in the optical axis direction and the direction perpendicular to the optical axis.
従来の撮像装置としては、撮像レンズを保持(固定)するレンズ保持部材(レンズホルダ)、レンズ保持部材を固定すると共に外装を形成するフロントケース、撮像素子を実装固定する基板等を備え、レンズ保持部材に保持(固定)された撮像レンズの背面に撮像レンズを受け入れる凹状の受け部を設け、フロントケースの背面に基板をネジ締めにより固定するためのポスト(ネジ穴)を設け、基板にネジを通すための貫通孔を設け、撮像レンズを保持したレンズ保持部材をフロントケースに固定し、撮像素子を実装した基板をフロントケースの背後から近づけて、撮像素子を撮像レンズの受け部に嵌め込むことにより、撮像レンズの光軸に垂直な方向における撮像素子の位置決めを行い、ネジを締結して基板をフロントケースに固定するものが知られている(例えば、特許文献1を参照)。 Conventional imaging devices include a lens holding member (lens holder) for holding (fixing) an imaging lens, a front case for fixing the lens holding member and forming an exterior, a substrate for mounting and fixing an imaging element, and the like. A concave receiving part for receiving the imaging lens is provided on the back of the imaging lens held (fixed) on the member, and a post (screw hole) for fixing the board by screwing is provided on the back of the front case. Provide a through-hole to pass through, fix the lens holding member that holds the imaging lens to the front case, bring the board on which the imaging element is mounted close from the back of the front case, and fit the imaging element into the receiving part of the imaging lens To position the imaging device in the direction perpendicular to the optical axis of the imaging lens, and fasten the screws to fix the board to the front case. Is known (e.g., see Patent Document 1).
この撮像装置においては、複数のネジを用いて基板を締め込むことにより、光軸方向の位置を調整することはできても、その締め込みの際にネジの回転に伴って基板が回転しあるいはネジの締め込み過ぎにより基板が沈み込む等の影響により、光軸方向あるいは光軸に垂直な方向の位置決めがずれてしまう虞があった。 In this imaging apparatus, even if the position in the optical axis direction can be adjusted by tightening the substrate using a plurality of screws, the substrate rotates with the rotation of the screws during the tightening or There is a possibility that the positioning in the optical axis direction or the direction perpendicular to the optical axis may be shifted due to the influence of the substrate sinking due to excessive tightening of screws.
本発明は、上記従来技術の事情に鑑みて成されたものであり、その目的とするところは、構造の簡素化等を図りつつ、光軸に対する撮像素子の位置調整後の固定に際し位置ずれし難く、落下等の衝撃力に対する耐衝撃性を低くすることなく、機能上の信頼性を向上させることのできる撮像装置を提供することにある。 The present invention has been made in view of the circumstances of the above-described prior art, and an object of the present invention is to shift the position when fixing the image pickup element with respect to the optical axis after adjusting the position while simplifying the structure. It is difficult to provide an imaging apparatus that can improve functional reliability without reducing impact resistance against impact force such as dropping.
本発明の第1の撮像装置は、光軸をもつ撮像レンズと、撮像レンズを保持するレンズ保持部材と、撮像レンズを通して結像された被写体像を撮像する撮像素子と、撮像素子を固定する固定板を備え、固定板はレンズ保持部材と非接触の状態で接着剤を介してレンズ保持部材に固定される撮像装置であって、上記固定板と非接触に配置されて固定板の脱落を規制する規制部を有すると共にレンズ保持部材に連結される連結部材と、連結部材と固定板の間に介在する接着剤とを含む、ことを特徴としている。 A first imaging device of the present invention includes an imaging lens having an optical axis, a lens holding member that holds the imaging lens, an imaging element that captures a subject image formed through the imaging lens, and a fixed that fixes the imaging element. An image pickup device that includes a plate and is fixed to the lens holding member via an adhesive in a non-contact state with the lens holding member, and is disposed in a non-contact manner with the fixing plate to restrict the fixing plate from falling off. And a connecting member connected to the lens holding member, and an adhesive interposed between the connecting member and the fixing plate.
この構成によれば、撮像レンズ(の光軸)に対する撮像素子の光軸位置調整(光軸方向の位置合わせ、光軸に垂直な方向の位置合わせ、光軸に対する傾き合わせ等)の後に、撮像レンズを保持したレンズ保持部材と撮像素子を固定した固定板とを両者の間に介在する接着剤により固着させると共に、レンズ保持部材に連結された(規制部を有する)連結部材と固定板とを両者の間に介在する接着剤により固着させるため、位置調整のずれを防止できると共に、仮にレンズ保持部材と固定板との間の接着剤が外部からの衝撃力等により剥がれたとしても、連結部材の規制部(及び連結部材と固定板の間に介在する接着剤)により固定板(及び撮像素子)の脱落を防止することができる。 According to this configuration, after the optical axis position adjustment (alignment in the optical axis direction, alignment in the direction perpendicular to the optical axis, tilt alignment with respect to the optical axis, etc.) of the imaging element with respect to the imaging lens (its optical axis), imaging is performed. The lens holding member holding the lens and the fixing plate fixing the imaging element are fixed by an adhesive interposed between them, and the connecting member (having a restricting portion) connected to the lens holding member and the fixing plate Since it is fixed by the adhesive interposed between the two, it is possible to prevent positional adjustment deviation, and even if the adhesive between the lens holding member and the fixing plate is peeled off by an external impact force or the like, the connecting member The restriction plate (and the adhesive interposed between the connecting member and the fixing plate) can prevent the fixing plate (and the image sensor) from falling off.
これによれば、構造の簡素化等を達成しつつ、光軸に対する撮像素子の位置調整後の固定に際し位置ずれし難く、固定板の外縁部のみでなく固定板の中央付近においても接着固定がなされることにより落下等の衝撃力に対する耐衝撃性が高く、部品(固定板、撮像素子等)の脱落等を防止でき、機能上の信頼性を向上させることのできる撮像装置が得られる。 According to this, while achieving simplification of the structure and the like, it is difficult for the image sensor to be displaced after the position adjustment of the image sensor with respect to the optical axis, and adhesive fixing is possible not only at the outer edge of the fixing plate but also near the center of the fixing plate. As a result, an imaging device that has high impact resistance against impact force such as dropping, can prevent parts (fixing plates, imaging elements, etc.) from falling off, and can improve functional reliability can be obtained.

It is possible to adopt a configuration in which the fixing plate is fixed to the fixing plate via an adhesive in a state where the fixing plate is not in contact with the fixing plate.
この構成によれば、撮像レンズを保持したレンズ保持部材の背面側に、所定の隙間をおいて(非接触の状態で)撮像素子を固定した固定板を対向させて保持し、頭部付きネジの軸部を固定板の背後から貫通孔に通してレンズ保持部材のネジ穴に捩じ込んで固定板と非接触の状態に保持し、レンズ保持部材(の背面側)と固定板(の外縁部)の間に接着剤を注入し(この接着剤は、レンズ保持部材の背面側又は固定板の外縁部に予め塗布されていてもよい)、頭部付きネジと固定板の間に接着剤を注入し、光軸位置調整を行った後に、接着剤を(例えば紫外線照射により)固化することにより、光軸調整後の位置ずれを防止できると共に、耐衝撃性の高い撮像装置を得ることができる。 According to this configuration, the fixing plate on which the imaging element is fixed is opposed to and held on the back side of the lens holding member that holds the imaging lens with a predetermined gap (in a non-contact state). The shaft part of the lens is passed through the through-hole from the back of the fixing plate and screwed into the screw hole of the lens holding member to hold it in a non-contact state with the fixing plate. (This adhesive may be pre-applied to the back side of the lens holding member or the outer edge of the fixing plate), and the adhesive is injected between the screw with the head and the fixing plate.

The lens holding member that holds the lens and the fixing plate that fixes the imaging element are fixed by an adhesive interposed therebetween, and the connecting projection and the fixing plate that are integrally formed with the lens holding member (having a regulating portion) Is fixed by an adhesive interposed between them, so that the positional adjustment can be prevented from being displaced, and even if the adhesive between the lens holding member and the fixing plate is peeled off by an external impact force or the like, The fixing plate (and the image sensor) can be prevented from falling off by the restricting portion of the connecting protrusion (and the adhesive interposed between the connecting protrusion and the fixing plate).
これによれば、構造の簡素化等を達成しつつ、光軸に対する撮像素子の位置調整後の固定に際し位置ずれし難く、落下等の衝撃力に対する耐衝撃性を低下させることなく、機能上の信頼性を向上させることのできる撮像装置が得られる。 According to this, while achieving simplification of the structure and the like, it is difficult to be displaced when fixing the image sensor with respect to the optical axis after the position adjustment, and functionally without reducing impact resistance against impact force such as dropping.
