　典型的なマイクロカメラユニットにおいては、焦点の調整、焦点距離の調整等のために、形状記憶合金（ＳＭＡ）アクチュエーター、ボイスコイルモーター等のアクチュエーターによりレンズが動かされ、結像の乱れを抑制するために、板バネ等の平行案内機構によりレンズの姿勢が維持されレンズが駆動方向に案内される。例えば、特許文献１に記載された駆動モジュールにおいては、ＳＭＡアクチュエーターによりレンズが動かされ、板バネによりレンズの姿勢が維持されレンズが駆動方向に案内される。 In a typical micro camera unit, the lens is moved by an actuator such as a shape memory alloy (SMA) actuator or a voice coil motor to adjust the focal point, the focal length, etc., so as to suppress disturbance of the image formation. Furthermore, the posture of the lens is maintained by a parallel guide mechanism such as a leaf spring, and the lens is guided in the driving direction. For example, in the driving module described in Patent Document 1, the lens is moved by the SMA actuator, the posture of the lens is maintained by the leaf spring, and the lens is guided in the driving direction.

The arrangement positions 185 to 188 occupy the second line from the front. The arrangement positions 189 to 192 occupy the third line from the front.

Arrangement positions 182, 186, 190 and 194 occupy the second row from the left. The arrangement positions 183, 187, 191 and 195 occupy the third row from the left. The arrangement positions 184, 188, 192 and 196 occupy the fourth column from the left.
　１４個の上レンズ１１６は、マルチアレイレンズ１１０の上配列面１３０にある。１４個の下レンズ１１８は、マルチアレイレンズ１１０の下配列面１３２にある。配置位置１８１～１８３，１８５～１９２及び１９４～１９６の各々には、１個の上レンズ１１６及び１個の下レンズ１１８が配置される。２個の被結合部１２０は、マルチアレイレンズ１１０の下配列面１３２にある。配置位置１８４及び１９３の各々には、１個の被結合部１２０が配置される。 The 14 upper lenses 116 are on the upper arrangement surface 130 of the multi-array lens 110. The 14 lower lenses 118 are on the lower arrangement surface 132 of the multi-array lens 110. One upper lens 116 and one lower lens 118 are arranged at each of the arrangement positions 181 to 183, 185 to 192, and 194 to 196. The two coupled portions 120 are on the lower arrangement surface 132 of the multi-array lens 110. One coupled portion 120 is disposed at each of the placement positions 184 and 193.
　２個の板状ＳＭＡアクチュエーター１２２は、マルチアレイレンズ１１０を駆動方向に動かす駆動力を発生し、駆動力をマルチアレイレンズ１１０に直接的に作用させ、マルチアレイレンズ１１０を支持体１０８に対して動かす。２個の板状ＳＭＡアクチュエーター１２２が他の種類のアクチュエーターに置き換えられてもよい。例えば、２個の板状ＳＭＡアクチュエーター１２２が線状ＳＭＡアクチュエーター、ボイスコイルモーター（ＶＣＭ）アクチュエーター、バイメタルアクチュエーター、圧電アクチュエーター等に置き換えられてもよい。２個の板状ＳＭＡアクチュエーター１２２からマルチアレイレンズ１１０へ駆動力を伝達する機構が設けられ、２個の板状ＳＭＡアクチュエーター１２２が駆動力をマルチアレイレンズ１１０に当該機構を介して間接的に作用させてもよい。２個の板状ＳＭＡアクチュエーター１２２は、マルチアレイレンズ１１０の下配列面１３２の中心に対称に駆動力を作用させる。これにより、マルチアレイレンズ１１０の姿勢を維持することが容易になる。 The two plate-like SMA actuators 122 generate a driving force that moves the multi-array lens 110 in the driving direction, cause the driving force to act directly on the multi-array lens 110, and cause the multi-array lens 110 to move relative to the support 108. move. The two plate-like SMA actuators 122 may be replaced with other types of actuators. For example, the two plate-like SMA actuators 122 may be replaced with a linear SMA actuator, a voice coil motor (VCM) actuator, a bimetal actuator, a piezoelectric actuator, or the like. A mechanism for transmitting a driving force from the two plate-like SMA actuators 122 to the multi-array lens 110 is provided, and the two plate-like SMA actuators 122 indirectly act on the multi-array lens 110 via the mechanism. You may let them. The two plate-like SMA actuators 122 apply driving force symmetrically to the center of the lower arrangement surface 132 of the multi-array lens 110. This facilitates maintaining the posture of the multi-array lens 110.
　板状ＳＭＡアクチュエーター１２４の結合部１３４は、支持体１０８に結合される。板状ＳＭＡアクチュエーター１２４の結合部１３６は、マルチアレイレンズ１１０の被結合部１２０に接着により結合される。 The coupling part 134 of the plate-like SMA actuator 124 is coupled to the support 108. The coupling portion 136 of the plate-like SMA actuator 124 is coupled to the coupled portion 120 of the multi-array lens 110 by adhesion.
　マルチアレイレンズ１１０の被結合部１２０は、切り目が形成された環１３８を備える。板状ＳＭＡアクチュエーター１２４の結合部１３６は、切れ目が形成された環１３８の内部に収容される。接着剤は、マルチアレイレンズ１１０の被結合部１２０及び板状ＳＭＡアクチュエーター１２４の結合部１３６に跨って塗布された後に硬化させられ、接着剤の硬化物１１４に変化する。板状ＳＭＡアクチュエーター１２４の結合部１３６がマルチアレイレンズ１１０の被結合部１２０に接着以外により結合されてもよい。例えば、板状ＳＭＡアクチュエーター１２４の結合部１３６がマルチアレイレンズ１１０の被結合部１２０に溶着、圧入、加締め又はねじ締結により結合されてもよい。 The coupled portion 120 of the multi-array lens 110 includes a ring 138 in which a cut is formed. The coupling portion 136 of the plate-like SMA actuator 124 is accommodated in the ring 138 in which a cut is formed. The adhesive is cured after being applied across the coupled portion 120 of the multi-array lens 110 and the coupled portion 136 of the plate-like SMA actuator 124, and changes to a cured product 114 of the adhesive. The coupling portion 136 of the plate-like SMA actuator 124 may be coupled to the coupled portion 120 of the multi-array lens 110 by other than adhesion. For example, the coupling portion 136 of the plate-like SMA actuator 124 may be coupled to the coupled portion 120 of the multi-array lens 110 by welding, press-fitting, caulking, or screw fastening.
　平行案内機構１２４は、マルチアレイレンズ１１０の姿勢を維持したまま、マルチアレイレンズ１１０を駆動方向に案内する。 The parallel guide mechanism 124 guides the multi-array lens 110 in the driving direction while maintaining the posture of the multi-array lens 110.
　上板バネ１２６の結合部１４０は、支持体１０８に結合される。上板バネ１２６の結合部１４２は、マルチアレイレンズ１１０の上配列面１３０に結合される。 The coupling portion 140 of the upper leaf spring 126 is coupled to the support 108. The coupling portion 142 of the upper leaf spring 126 is coupled to the upper arrangement surface 130 of the multi-array lens 110.
　下板バネ１２８の結合部１４４は、支持体１０８に結合される。下板バネ１２８の結合部１４６は、マルチアレイレンズ１１０の下配列面１３２に結合される。 The connecting portion 144 of the lower leaf spring 128 is connected to the support 108. The coupling portion 146 of the lower leaf spring 128 is coupled to the lower arrangement surface 132 of the multi-array lens 110.
　上板バネ１２６及び下板バネ１２８は、撮像素子１０４の撮像面１４８と平行をなす。上板バネ１２６及び下板バネ１２８により、上配列面１３０及び下配列面１３２が撮像素子１０４の撮像面１４８と平行をなす姿勢にマルチアレイレンズ１１０の姿勢が維持される。 The upper leaf spring 126 and the lower leaf spring 128 are parallel to the imaging surface 148 of the imaging element 104. The upper plate spring 126 and the lower plate spring 128 maintain the posture of the multi-array lens 110 so that the upper arrangement surface 130 and the lower arrangement surface 132 are parallel to the imaging surface 148 of the image sensor 104.
　平行案内機構１２４が他の種類の平行案内機構に置き換えられてもよい。例えば、平行案内機構１２４が、線バネを備える平行案内機構、コイルバネを備える平行案内機構、案内軸を備える平行案内機構、リンクを備える平行案内機構等に置き換えられてもよい。 The parallel guide mechanism 124 may be replaced with another type of parallel guide mechanism. For example, the parallel guide mechanism 124 may be replaced with a parallel guide mechanism including a wire spring, a parallel guide mechanism including a coil spring, a parallel guide mechanism including a guide shaft, a parallel guide mechanism including a link, and the like.
　マルチアレイレンズ１１０の駆動方向は、マルチアレイレンズ１１０の光軸１５０と平行をなす方向に維持され、撮像素子１０４の撮像面１４８と垂直をなす方向に維持される。 The driving direction of the multi-array lens 110 is maintained in a direction parallel to the optical axis 150 of the multi-array lens 110, and is maintained in a direction perpendicular to the imaging surface 148 of the image sensor 104.
　マルチアレイレンズ１１０は、レンズユニット１０２の焦点を調整するために動かされる。マルチアレイレンズ１１０が、レンズユニット１０２の焦点距離を調整するために動かされてもよい。複数のマルチアレイレンズ１１０がある場合は、マルチアレイレンズ１１０がレンズユニット１０２のズーミングのために動かされてもよい。 The multi-array lens 110 is moved to adjust the focal point of the lens unit 102. The multi-array lens 110 may be moved to adjust the focal length of the lens unit 102. When there are a plurality of multi-array lenses 110, the multi-array lenses 110 may be moved for zooming the lens unit 102.
　撮像素子１０４は、１４個の上レンズ１１６及び１４個の下レンズ１１８により結像された像を撮像する。撮像素子１０４が出力する撮像データは、ステレオ画像、三次元画像等の生成のために使用される。 The image sensor 104 captures an image formed by the 14 upper lenses 116 and the 14 lower lenses 118. The imaging data output from the imaging element 104 is used for generating a stereo image, a three-dimensional image, and the like.
　１４個の上レンズ１１６及び１４個の下レンズ１１８により結像された１４個の像は、１個の撮像素子１０４により撮像される。１４個の像が２個以上の撮像素子により撮像されてもよい。２個以上の撮像素子の各々は、１個の像を撮像してもよいし、２個以上の像を撮像してもよい。 The 14 images formed by the 14 upper lenses 116 and the 14 lower lenses 118 are imaged by one image sensor 104. Fourteen images may be captured by two or more image sensors. Each of the two or more imaging elements may capture one image, or may capture two or more images.
　配置位置１８４及び１９３は、１６個の配置位置１８１～１９６において最も外側に配置される。これにより、像を結ぶ光線束が２個の板状ＳＭＡアクチュエーター１２２により遮蔽されることを容易に回避できる。 The arrangement positions 184 and 193 are arranged on the outermost side in the 16 arrangement positions 181 to 196. Thereby, it can be easily avoided that the light beam connecting the images is blocked by the two plate-like SMA actuators 122.
　図４の模式図は、板状ＳＭＡアクチュエーター１２４の斜視図である。 4 is a perspective view of the plate-like SMA actuator 124. FIG.
　図４に示されるように、板状ＳＭＡアクチュエーター１２４は、板状ＳＭＡ１５２及び膜状ヒーター１５４を備える。膜状ヒーター１５４は、板状ＳＭＡ１５２の表面に形成される。膜状ヒーター１５４に電流が流れた場合は、膜状ヒーター１５４が発熱する。膜状ヒーター１５４が発する熱が板状ＳＭＡ１５２に伝わり、板状ＳＭＡアクチュエーター１２４の温度が上昇する。板状ＳＭＡアクチュエーター１２４の形状が平坦な形状から図１に示される湾曲した形状へ変化し、マルチアレイレンズ１１０を上方向に動かす駆動力がマルチアレイレンズ１１０に作用する。 As shown in FIG. 4, the plate-like SMA actuator 124 includes a plate-like SMA 152 and a film heater 154. The film heater 154 is formed on the surface of the plate SMA 152. When a current flows through the film heater 154, the film heater 154 generates heat. The heat generated by the film heater 154 is transmitted to the plate SMA 152, and the temperature of the plate SMA actuator 124 rises. The shape of the plate-like SMA actuator 124 changes from a flat shape to a curved shape shown in FIG. 1, and a driving force that moves the multi-array lens 110 upward acts on the multi-array lens 110.
　第１実施形態によれば、本来は下レンズが配置される配置位置１８４及び１９３にマルチアレイレンズ１１０の２個の被結合部１２０が配置され、マルチアレイレンズ１１０と駆動機構１１２との結合のために占有される空間が減少する。これにより、レンズユニット１０２が小型になる。なお、配置位置１８４及び１９３に配置される上レンズ及び下レンズがなくても、光学性能の低下はわずかである。 According to the first embodiment, the two coupled portions 120 of the multi-array lens 110 are arranged at the arrangement positions 184 and 193 where the lower lens is originally arranged, and the coupling of the multi-array lens 110 and the drive mechanism 112 is performed. This reduces the space occupied. Thereby, the lens unit 102 becomes small. Even if there is no upper lens and lower lens arranged at the arrangement positions 184 and 193, the optical performance is slightly reduced.

　配置位置１３６１，１３６２，１３６３，１３８８，１３８９及び１３９０は、３０個の配置位置１３６１，１３６２，１３６３，１３６４，・・・，１３８７，１３８８，１３８９及び１３９０において最も外側に配置される。これにより、像を結ぶ光線束が磁石１３３４により遮蔽されることを容易に回避できる。 Arrangement positions 1361, 1362, 1363, 1388, 1389 and 1390 are arranged on the outermost side in 30 arrangement positions 1361, 1362, 1363, 1364,..., 1387, 1388, 1389 and 1390. Thereby, it is possible to easily avoid that the light beam connecting the images is shielded by the magnet 1334.
