Description

本発明は、撮像装置に関し、特に携帯端末への内蔵に好適な小型で薄型の撮像装置と該撮像装置に用いられる撮像光学系に関するものである。   The present invention relates to an imaging apparatus, and more particularly to a small and thin imaging apparatus suitable for incorporation in a portable terminal and an imaging optical system used in the imaging apparatus.

従来より、小型で薄型の撮像装置が携帯電話機やＰＤＡ（Ｐｅｒｓｏｎａｌ Ｄｉｇｉｔａｌ Ａｓｓｉｓｔａｎｔ）等の小型、薄型の電子機器に搭載されるようになっており、これにより遠隔地へ音声情報だけでなく画像情報も相互に伝送することが可能となっている。これらの撮像装置に用いられる撮像素子としては、ＣＣＤ（Ｃｈａｒｇｅ Ｃｏｕｐｌｅｄ Ｄｅｖｉｃｅ）型イメージセンサやＣＭＯＳ（Ｃｏｍｐｌｅｍｅｎｔａｒｙ Ｍｅｔａｌ−Ｏｘｉｄｅ Ｓｅｍｉｃｏｎｄｕｃｔｏｒ）型イメージセンサ等の固体撮像素子が使用されている。   Conventionally, a small and thin imaging device is mounted on a small and thin electronic device such as a mobile phone or a PDA (Personal Digital Assistant), so that not only audio information but also image information can be transmitted to a remote place. It is possible to transmit to each other. As an image pickup element used in these image pickup apparatuses, a solid-state image pickup element such as a CCD (Charge Coupled Device) type image sensor or a CMOS (Complementary Metal-Oxide Semiconductor) type image sensor is used.

これら携帯端末に内蔵される撮像装置は、撮像素子の画素ピッチが非常に小さいことと、開口Ｆ値が２〜４程度のものであるため、像側の焦点深度は非常に浅くなり、撮像面に対する撮像光学系の光軸方向の位置決めには厳しい精度が要求されている。   These imaging devices built in these portable terminals have a very small pixel pitch of the imaging element and an aperture F value of about 2 to 4, so that the focal depth on the image side becomes very shallow, and the imaging surface Strict accuracy is required for positioning the imaging optical system with respect to the optical axis direction.

これに対し、撮像装置の撮像光学系の位置設定方法に関して提案がなされている。例えば、撮像装置の製造時のピント調整を不要とすべく、光学部材と一体で形成された脚部（支持部）を撮像素子に当接させ、弾性部材で光学部材を撮像素子方向に付勢することにより、撮像素子と光学部材の光軸方向の位置決めをおこなうものが開示されている（例えば、特許文献１参照）。
特開２００３−３７７５８号公報 On the other hand, proposals have been made regarding a position setting method for an imaging optical system of an imaging apparatus. For example, in order to eliminate the need for focus adjustment at the time of manufacturing the imaging device, a leg portion (support portion) formed integrally with the optical member is brought into contact with the imaging element, and the optical member is biased toward the imaging element by an elastic member. By doing so, a device that positions the imaging element and the optical member in the optical axis direction is disclosed (for example, see Patent Document 1).
JP 2003-37758 A

近年、携帯端末に内蔵される撮像装置は、より高画質を目指し、高画素の撮像素子の搭載されるものが増加しつつある。この高画素化は、上記の撮像光学系の光軸方向の位置決めに関して、従来より更に厳しい精度が必要となる。また、この撮像素子の高画素化により、要求される撮像光学系の結像性能についても、従来に比べ、より向上させる必要がある。   In recent years, the number of image pickup devices built in mobile terminals has been increasing in order to achieve higher image quality. In order to increase the number of pixels, the positioning accuracy in the optical axis direction of the imaging optical system described above requires higher accuracy than before. In addition, by increasing the number of pixels of the image sensor, it is necessary to further improve the imaging performance of the required imaging optical system as compared with the related art.

この撮像光学系の結像性能の向上策としては、撮像光学系を構成するレンズ枚数を増加させることで対応可能である。しかし、撮像光学系のレンズ構成枚数を増加させた場合、個々のレンズの間隔や光軸合わせをばらつき無く正確に組み立てる必要がある。これは、レンズ相互の間隔や光軸合わせに誤差を生じると、焦点位置のみならず結像性能にも変化が及ぶためである。   As a measure for improving the imaging performance of the imaging optical system, it can be dealt with by increasing the number of lenses constituting the imaging optical system. However, when the number of lenses constituting the imaging optical system is increased, it is necessary to accurately assemble the intervals between the individual lenses and the alignment of the optical axes. This is because if an error occurs in the distance between the lenses or the optical axis alignment, not only the focal position but also the imaging performance changes.

一方、撮像光学系と撮像素子の光軸方向の位置決めを正確に保つ方法として提案されている、上記特許文献１に記載のレンズ枚数を複数にした撮像装置の例の場合、以下の問題がある。   On the other hand, in the example of the imaging apparatus having a plurality of lenses described in Patent Document 1 proposed as a method for accurately maintaining the positioning of the imaging optical system and the imaging element in the optical axis direction, there are the following problems. .

像側レンズと被写体側レンズは、径方向で嵌合して軸合わせがなされ、光軸方向では絞り板をスペーサとして、レンズ間距離を規制している。このように撮像光学系を構成すると、光軸方向のレンズ間隔がスペーサの厚みのばらつきに依存することになる。撮像光学系のレンズ構成枚数が更に増加した場合、このスペーサのばらつきの累積がレンズ間隔の誤差となり、上述の焦点位置と結像性能のばらつきとなる問題を生じることになる。   The image side lens and the subject side lens are fitted and aligned in the radial direction, and in the optical axis direction, the distance between the lenses is restricted by using a diaphragm plate as a spacer. When the imaging optical system is configured in this way, the lens interval in the optical axis direction depends on the variation in the thickness of the spacer. When the number of lenses constituting the imaging optical system is further increased, the accumulated variation in the spacers becomes an error in the lens interval, which causes the above-described variation in the focal position and the imaging performance.

また、積み上げ式にレンズを当接して撮像光学系を組み立てる場合、レンズを３枚以上使用すると、両端に配置されたレンズの光軸及び間隔の誤差は間挿されたレンズの誤差が累積された状態になる。このため、撮像光学系の焦点位置と結像性能が安定せず、この撮像光学系を使用した撮像装置は、量産時の良品率の低下を誘引することになる。   Also, when assembling the imaging optical system by abutting the lenses in a stacked manner, if three or more lenses are used, the errors of the interpolated lenses are accumulated as the errors in the optical axes and intervals of the lenses arranged at both ends. It becomes a state. For this reason, the focal position and imaging performance of the imaging optical system are not stable, and an imaging apparatus using this imaging optical system invites a decrease in the yield rate during mass production.

本発明は上記問題に鑑み、撮像光学系が３枚以上の多数枚で構成される場合でも、レンズ間隔及び光軸合わせを容易に保証することができ、組み立て時に無調整で所定の被写体距離に焦点の合った撮像光学系及び撮像装置を得ることを目的とするものである。   In view of the above problems, the present invention can easily guarantee the lens interval and optical axis alignment even when the imaging optical system is composed of a large number of three or more, and can be adjusted to a predetermined subject distance without adjustment during assembly. An object is to obtain an imaging optical system and an imaging apparatus that are in focus.

（第１の実施の形態）
図３は、本発明の第１の実施の形態に係る撮像光学系及び撮像装置の一部省略断面図である。同図は、図２に示すＦ−Ｆ線で切断した断面を示している。以下説明の重複を避けるため、同部材には同符号を付与して説明する。 (First embodiment)
FIG. 3 is a partially omitted cross-sectional view of the image pickup optical system and the image pickup apparatus according to the first embodiment of the present invention. This figure shows a cross section cut along line FF shown in FIG. Hereinafter, in order to avoid duplication of explanation, the same reference numerals are given to the same members.

同図において、外枠部材１２の内部は、第１レンズ１、撮像光学系の開口Ｆ値を決める開口絞り４、第２レンズ２、不要光遮断のための固定絞り５ａ、５ｂ、第３レンズ３、で構成された撮像光学系５０と、プリント基板１１上に実装された撮像素子８、弾性部材であるコイルバネ９、蓋部材１３で構成されている。   In the figure, the outer frame member 12 includes a first lens 1, an aperture stop 4 that determines the aperture F value of the imaging optical system, a second lens 2, fixed apertures 5a and 5b for blocking unnecessary light, and a third lens. 3, the image pickup optical system 50 mounted on the printed circuit board 11, a coil spring 9 that is an elastic member, and a lid member 13.

なお、外枠部材１２はプリント基板１１に接着剤Ｃにより接着固定され、蓋部材１３は外枠部材１２に接着剤Ｂにより接着固定されている。   The outer frame member 12 is bonded and fixed to the printed circuit board 11 with an adhesive C, and the lid member 13 is bonded and fixed to the outer frame member 12 with an adhesive B.

同図に示すように、第１レンズ１は、他の第２レンズ２及び第３レンズ３を個々に当接させる当接部１ｂ及び１ｃが一体で形成されている。この当接部１ｂには第２レンズ２が当接され、接着固定される。当接部１ｃには第３レンズ３が当接され、接着固定されて撮像光学系５０はユニット化されている。また、第２レンズ２、第３レンズ３の径方向では、それぞれ第１レンズ１に形成された嵌合部１ｆ、１ｇと嵌合している。この嵌合部１ｆ、１ｇは、第２レンズ２、第３レンズ３の径方向の寸法と精密に嵌合するよう形成されている。   As shown in the figure, the first lens 1 is integrally formed with contact portions 1b and 1c for contacting the other second lens 2 and third lens 3 individually. The second lens 2 is brought into contact with the contact portion 1b and fixed by adhesion. The third lens 3 is brought into contact with the contact portion 1c and bonded and fixed, so that the imaging optical system 50 is unitized. Further, in the radial direction of the second lens 2 and the third lens 3, they are fitted with fitting portions 1 f and 1 g formed on the first lens 1, respectively. The fitting portions 1f and 1g are formed so as to be precisely fitted to the radial dimensions of the second lens 2 and the third lens 3.

この当接部１ｂ、１ｃと嵌合部１ｆ、１ｇにより、第１レンズ１に対して第２レンズ２と第３レンズ３は、それぞれの光軸方向の間隔と光軸のずれを最少にした撮像光学系とすることができる。   By the contact portions 1b and 1c and the fitting portions 1f and 1g, the second lens 2 and the third lens 3 with respect to the first lens 1 minimize the distance between the optical axes and the deviation of the optical axes. It can be set as an imaging optical system.

更に、第１レンズ１には、図示のように、撮像光学系５０を支持する支持部１ｄが一体で形成されており、光軸に直交する方向は外枠部材１２に形成された嵌合部１２ｋにより嵌合されて位置決めされ、光軸方向ではコイルバネ９による付勢力により支持部１ｄが撮像素子８上に当接するようになっている。この第１レンズ１に形成された支持部１ｄにより、撮像素子８の光電変換面と撮像光学系５０との光軸方向の位置決めがなされるようになっている。   Further, as shown in the figure, the first lens 1 is integrally formed with a support portion 1 d that supports the imaging optical system 50, and a fitting portion formed on the outer frame member 12 in the direction orthogonal to the optical axis. The support portion 1d is brought into contact with the image pickup device 8 by the biasing force of the coil spring 9 in the optical axis direction. The support portion 1d formed on the first lens 1 positions the photoelectric conversion surface of the image sensor 8 and the imaging optical system 50 in the optical axis direction.

このように、撮像光学系５０を、構成するレンズのみで他の部材を介さず構成することにより、撮像光学系５０の相互のレンズ間隔に関する誤差やばらつきを最少にして組み立てることができ、撮像光学系の焦点位置と結像性能を安定させ量産時の良品率を向上させることができる。   As described above, by configuring the imaging optical system 50 with only the constituent lenses without any other members, the imaging optical system 50 can be assembled with minimum errors and variations related to the distance between the lenses of the imaging optical system 50. The focus position and imaging performance of the system can be stabilized and the yield rate during mass production can be improved.

また、第１レンズ１の片側（本例では像面側）に第２レンズ２と第３レンズ３を当接させる当接部１ｂ、１ｃ及び嵌合部１ｆ、１ｇを形成することで、第１レンズ１を成形する金型の一方に一体で当接部１ｂ、１ｃ及び嵌合部１ｆ、１ｇの形状を形成することができる。このことは、間隔に関わる寸法精度を確保できるだけでなく、偏芯誤差をも抑えることが可能となり、相互のレンズ間隔の精度向上に加えて、各レンズ間の光軸合わせ精度も向上させることが可能となる。   In addition, by forming contact portions 1b and 1c and fitting portions 1f and 1g for contacting the second lens 2 and the third lens 3 on one side (image surface side in this example) of the first lens 1, The shape of the contact portions 1b and 1c and the fitting portions 1f and 1g can be formed integrally with one of the molds for molding the one lens 1. This not only ensures the dimensional accuracy related to the distance, but also suppresses eccentricity errors, and in addition to improving the accuracy of the mutual lens distance, it can also improve the accuracy of optical axis alignment between the lenses. It becomes possible.

なお、本例は第１レンズ１の光軸方向の位置ずれが、焦点位置ずれに対し最も敏感な撮像光学系に好適な構成である。   In this example, the first lens 1 is suitable for an imaging optical system in which the positional deviation in the optical axis direction is most sensitive to the focal positional deviation.

即ち、第１レンズ１が焦点位置のずれに関する誤差感度の最も高いレンズである場合に好適なものであり、誤差感度の最も高い第１レンズに支持部１ｄを設けて、第１レンズ１と撮像素子８との位置関係を他の部材を介さないことで正確に設定でき、この第１レンズ１に撮像光学系を構成する他のレンズを個々に当接させ保持することで、光学系内のレンズ間隔に関する誤差を最少にすることができ、組み立て時に無調整で所定の被写体距離に焦点の合った撮像装置を得ることが可能となる。   That is, it is suitable when the first lens 1 is the lens having the highest error sensitivity related to the shift of the focal position. The first lens 1 having the highest error sensitivity is provided with the support portion 1d so that the first lens 1 and the first lens 1 are imaged. The positional relationship with the element 8 can be accurately set without passing through other members, and the other lenses constituting the imaging optical system are brought into contact with each other and held on the first lens 1 so that the inside of the optical system can be maintained. An error relating to the lens interval can be minimized, and an image pickup apparatus that is focused on a predetermined subject distance without adjustment during assembly can be obtained.

同図に示すように、第３レンズ３は、他の第１レンズ１及び第２レンズ２を個々に当接させる当接部３ｂ及び３ｃが一体で形成されている。この当接部３ｃには第２レンズ２が当接され、接着固定される。当接部３ｂには第１レンズ１が当接され、接着固定され撮像光学系５０はユニット化されている。また、第１レンズ１、第２レンズ２の径方向では、それぞれ第３レンズ３に形成された嵌合部３ｆ、３ｇと嵌合している。この嵌合部３ｆ、３ｇは、第１レンズ１、第２レンズ２の径方向の寸法と精密に嵌合するよう形成されている。   As shown in the figure, the third lens 3 is integrally formed with contact portions 3b and 3c for contacting the other first lens 1 and second lens 2 individually. The second lens 2 is in contact with the contact portion 3c and is fixed by adhesion. The first lens 1 is in contact with the contact portion 3b, and is fixed by adhesion, and the imaging optical system 50 is unitized. Further, in the radial direction of the first lens 1 and the second lens 2, they are fitted with fitting portions 3f and 3g formed on the third lens 3, respectively. The fitting portions 3f and 3g are formed so as to be precisely fitted with the radial dimensions of the first lens 1 and the second lens 2.

この当接部３ｂ、３ｃと嵌合部３ｆ、３ｇにより、第３レンズ３に対して第１レンズ１と第２レンズ２は、それぞれの光軸方向の間隔と光軸のずれを最少にした撮像光学系とすることができる。   Due to the contact portions 3b and 3c and the fitting portions 3f and 3g, the first lens 1 and the second lens 2 with respect to the third lens 3 minimize the distance in the optical axis direction and the shift of the optical axis. It can be set as an imaging optical system.

更に、第３レンズ３には、図示のように、撮像光学系５０を支持する支持部３ｄが一体で形成されており、光軸に直交する方向は外枠部材１２に形成された嵌合部１２ｋにより嵌合されて位置決めされ、光軸方向ではコイルバネ９による付勢力により支持部３ｄが撮像素子８上に当接するようになっている。この第３レンズ３に形成された支持部３ｄにより、撮像素子８の光電変換面と撮像光学系５０との光軸方向の位置決めがなされるようになっている。   Further, as shown in the figure, the third lens 3 is integrally formed with a support portion 3d that supports the imaging optical system 50, and a direction perpendicular to the optical axis is a fitting portion formed on the outer frame member 12. The support portion 3d abuts on the image sensor 8 by the biasing force of the coil spring 9 in the optical axis direction. The support portion 3d formed on the third lens 3 positions the photoelectric conversion surface of the image sensor 8 and the image pickup optical system 50 in the optical axis direction.

この第２の実施の形態においても、撮像光学系５０を、構成するレンズのみで他の部材を介さず構成することにより、撮像光学系５０の相互のレンズ間隔に関する誤差やばらつきを最少にして組み立てることができ、撮像光学系の焦点位置と結像性能を安定させ量産時の良品率を向上させることができる。   Also in the second embodiment, the imaging optical system 50 is configured by using only the constituting lenses and not through other members, thereby assembling the imaging optical system 50 with minimal errors and variations related to the mutual lens interval. It is possible to stabilize the focal position and imaging performance of the imaging optical system and improve the yield rate during mass production.

また、第３レンズ３の片側（本例では被写体側）に第１レンズ１と第２レンズ２を当接させる当接部３ｂ、３ｃ及び嵌合部３ｆ、３ｇを形成することで、第３レンズ３を成形する金型の一方に一体で当接部３ｂ、３ｃ及び嵌合部３ｆ、３ｇに相当する形状を形成することができる。このことは、間隔に関わる寸法精度を確保できるだけでなく、偏芯誤差をも抑えることが可能となり、相互のレンズ間隔の精度向上に加えて、各レンズ間の光軸合わせ精度も向上させることが可能となる。   Further, by forming contact portions 3b and 3c and fitting portions 3f and 3g for contacting the first lens 1 and the second lens 2 on one side of the third lens 3 (subject side in this example), the third lens 3 is formed. A shape corresponding to the contact portions 3b and 3c and the fitting portions 3f and 3g can be formed integrally with one of the molds for molding the lens 3. This not only ensures the dimensional accuracy related to the distance, but also suppresses eccentricity errors, and in addition to improving the accuracy of the mutual lens distance, it can also improve the accuracy of optical axis alignment between the lenses. It becomes possible.

なお、本例は第３レンズ３の光軸方向の位置ずれが、焦点位置ずれに対し最も敏感な撮像光学系に好適な構成である。   This example is a configuration suitable for an imaging optical system in which the positional deviation of the third lens 3 in the optical axis direction is most sensitive to the focal positional deviation.

即ち、第３レンズ３が焦点位置のずれに関する誤差感度の最も高いレンズである場合に好適なものであり、誤差感度の最も高い第３レンズ３に支持部３ｄを設けて、第３レンズ３と撮像素子８との位置関係を他の部材を介さないことで正確に設定でき、この第３レンズ３に撮像光学系を構成する他のレンズを個々に当接させ保持することで、光学系内のレンズ間隔に関する誤差を最少にすることができ、組み立て時に無調整で所定の被写体距離に焦点の合った撮像装置を得ることが可能となる。   That is, it is suitable for the case where the third lens 3 is the lens having the highest error sensitivity related to the shift of the focal position. The third lens 3 having the highest error sensitivity is provided with the support portion 3d. The positional relationship with the image pickup device 8 can be accurately set without using other members, and the other lenses constituting the image pickup optical system are individually brought into contact with and held by the third lens 3 so that the inside of the optical system can be maintained. Thus, it is possible to obtain an image pickup apparatus that is focused on a predetermined subject distance without adjustment at the time of assembly.

この当接部２ｂ、２ｃと嵌合部２ｆ、２ｇにより、第２レンズ２に対して第１レンズ１と第３レンズ３は、それぞれの光軸方向の間隔と光軸のずれを最少にした撮像光学系とすることができる。   By the contact portions 2b and 2c and the fitting portions 2f and 2g, the first lens 1 and the third lens 3 minimize the distance between the respective optical axes and the optical axis with respect to the second lens 2.
