Description

本発明は、カメラのレンズホルダ部にレンズユニットを固定するレンズ固定構造に関する。   The present invention relates to a lens fixing structure for fixing a lens unit to a lens holder portion of a camera.

図４は、従来のレンズ固定構造を示す断面図である。このレンズ固定構造では、図４に示すように、レンズホルダ部１にレンズユニット３が六角穴付きの止めネジ５，７によって固定されている。止めネジ５，７を緩めることによりレンズユニット３を挿入方向Ａ上流側及び下流側に位置調節できるようになっている。なお、レンズユニット３のレンズホルダ部１への他の固定手段としては、止めネジ５，７の代わりに接着剤を用いたものがある。   FIG. 4 is a cross-sectional view showing a conventional lens fixing structure. In this lens fixing structure, as shown in FIG. 4, the lens unit 3 is fixed to the lens holder portion 1 by set screws 5 and 7 having hexagonal holes. The position of the lens unit 3 can be adjusted upstream and downstream in the insertion direction A by loosening the set screws 5 and 7. As another means for fixing the lens unit 3 to the lens holder portion 1, there is one using an adhesive instead of the set screws 5 and 7.

レンズユニット３は、複数のレンズからなるレンズ系１１と、そのレンズ系１１を保持する筒状の保持部材１３と、レンズ系１１を保持部材１３内に抜け止め保持する押さえ部材１５とを備えている。レンズホルダ部１は、カメラケース１７の前面部に一体的に設けられている。カメラケース１７内には、撮像素子１９と、撮像素子１９及びその他の回路構成が実装される基板２１，２３が備えられている。   The lens unit 3 includes a lens system 11 composed of a plurality of lenses, a cylindrical holding member 13 that holds the lens system 11, and a pressing member 15 that holds the lens system 11 in the holding member 13. Yes. The lens holder portion 1 is integrally provided on the front surface portion of the camera case 17. The camera case 17 includes an image sensor 19 and substrates 21 and 23 on which the image sensor 19 and other circuit configurations are mounted.

しかしながら、上述の従来技術では、レンズホルダ部１に止めネジ５，７のネジ穴を設ける必要があるため、次のような不都合がある。すなわち、レンズホルダ部１のネジ穴周辺に応力が集中するため、レンズホルダ部１の疲労破壊が生じる場合がある。また、ネジ穴加工のため、レンズホルダ部１のネジ穴の周辺面積を広くとる必要があり、構成が大型化する。また、止めネジ５，７からの応力が点状にレンズユニット３に与えられるため、レンズユニット３に与えられる応力に偏りが生じやすく、光軸のずれが生じる場合がある。   However, in the above-described prior art, since it is necessary to provide the screw holes of the set screws 5 and 7 in the lens holder portion 1, there are the following disadvantages. That is, since stress concentrates around the screw hole of the lens holder portion 1, the lens holder portion 1 may be fatigued. Further, since the screw hole is processed, it is necessary to increase the peripheral area of the screw hole of the lens holder portion 1, and the configuration is increased in size. Further, since the stress from the set screws 5 and 7 is applied to the lens unit 3 in the form of dots, the stress applied to the lens unit 3 is likely to be biased, and the optical axis may be shifted.

また、接着剤によりレンズユニット３を固定する構成では、接着剤の塗布、乾燥等に手間及び時間がかかり、コスト負担が大きいとともに、固定後にレンズユニット３の位置調節や脱着ができないという問題がある。   Further, in the configuration in which the lens unit 3 is fixed with an adhesive, there are problems that it takes time and effort to apply and dry the adhesive, the cost is high, and the position and adjustment of the lens unit 3 cannot be performed after fixing. .

そこで、本発明の解決すべき課題は、止めネジを用いることなく、小型かつ簡易な構成で、レンズユニットの位置調節及び脱着を可能とすることができるとともに、光軸のずれも防止でき、組み立ても容易なレンズ固定構造を提供することである。   Therefore, the problem to be solved by the present invention is that it is possible to adjust the position and detachment of the lens unit with a small and simple configuration without using a set screw, and to prevent the deviation of the optical axis and to assemble the lens unit. It is also to provide an easy lens fixing structure.
