在卡口模块300的背面部310收容在底座部530内的状态下，操作操作件110，中间卡口100沿第一方向20旋转。由此，中间卡口100的卡合部107和卡口模块300的卡合部303卡合，从而中间卡口100保持卡口模块300。
中间卡口100可拆装地固定在底座部530的前表面。中间卡口100可拆装地固定在包围底座部530的开口531的底座部530的前表面。中间卡口100是环状的第一卡口的一个示例。中间卡口100通过间隔件130，由螺丝551可拆装地固定在底座部530的前表面。卡口模块300可拆装地保持可更换镜头10，并可拆装地保持于中间卡口100。卡口模块300是环状的第二卡口的一个示例。
间隔件130布置在底座部530的前表面和卡口模块300的背面之间，调整卡口模块300与图像传感器510的摄像面之间的距离即法兰焦距。通过调整间隔件130的厚度，可以将卡口模块300和图像传感器510的摄像面之间的法兰焦距设定为期望的距离。也可以使用多个间隔件130来调整法兰焦距。
底座部530在凹部550内包括锁定件560，其能够在将光学滤波器520锁定在底座部530的状态与不将光学滤波器520锁定在底座部530的状态之间进行切换。
锁定件560以旋转轴561为中心相对于底座部530旋转，而在将光学滤波器520锁定在底座部530的状态与不将光学滤波器520锁定在底座部530的状态之间进行切换。
图5A示出了从底座部530拆卸光学滤波器520，锁定件560不锁定底座部530这一状态。图5B示出了底座部530安装光学滤波器520，锁定件560锁定光学滤波器520以免光学滤波器520从底座部530脱落这一状态。底座部530在凹部550内具有布置光学滤波器520的槽551。槽551可以是具有与光学滤波器520的外形对应的形状的槽。
锁定件560包括可旋转地支撑旋转轴561的圆形主体部562以及从主体部562的外周突出的爪部563。通过爪部563位于光学滤波器520之上，将光学滤波器520锁定于凹部550内的槽551。
图6示出了从卡口模块300的背面侧观察到的图。图7A是从正面观察到的摄像装置500的图。图7B是图7A所示的F-F剖面图。卡口模块300的背面部310包括与锁定件560的主体部562配合的孔312。当锁定件560处于不锁定光学滤波器520的状态下时，爪部563与孔312不配合，卡口模块300的背面部310与凹部550不配合。如图7B所示，爪部563被背面部310干涉，主体部562无法嵌入孔312。由于卡口模块300的背面部310无法完全嵌入凹部550，因此卡口模块300无法安装到中间卡口100。由此，可以防止在光学滤波器520未被锁定件560锁定的状态下，卡口模块300被安装到中间卡口100。
图8A是从前表面侧观察到的中间卡口100、以及卡口模块300的一部分的分解立体图。图8B是从背面侧观察到的中间卡口100、以及卡口模块300的一部分的分解立体图。
卡口主体302是卡口模块300的一部分，是环状的部件。卡口主体302包括从外周面向外侧突出的多个卡合部303。此外，卡口主体302包括从内周面向内侧突出的多个卡合部304。可更换镜头10具备包括从外周面向外侧突出的卡合部的卡口，通过可更换镜头10的卡合部和卡口主体302的卡合部304卡合，使得可更换镜头10保持在卡口模块300上。中间卡口100包括环状的固定件102、环状的背面活动件104、环状的前表面活动件106以及操作件110。
固定件102可拆装地固定在底座部530的前表面。背面活动件104能够在与固定件102的背面接触的同时旋转。前表面活动件106包括从内周面向内侧突出的多个卡合部107。前表面活动件106布置在固定件102的前表面，能够与背面活动件104一同相对于固定件102旋转。在背面活动件104以及前表面活动件106之间存在固定件102的状态下，背面活动件104以及前表面活动件106互相固定。背面活动件104是第一活动件的一个示例。前表面活动件106是第二活动件的一个示例。操作件110固定在前表面活动件106的外周面。操作件110接受旋转背面活动件104以及前表面活动件106的操作。用户用指尖捏住操作件110，顺时针或逆时针旋转中间卡口100。
与背面活动件104的前表面接触的固定件102的背面具有相对于背面活动件104的旋转方向成一角度的倾斜面103。与固定件102的背面接触的背面活动件104的前表面具有相对 于背面活动件104的旋转方向成一角度的倾斜面105。固定件102沿固定件102的圆周具有多个倾斜面103。背面活动件104沿背面活动件104的圆周具有的多个倾斜面105。
背面活动件104在沿倾斜面103与前表面活动件106一同沿顺时针的第一方向20旋转的同时向底座部530侧移动。由此，通过前表面活动件106的卡合部107将卡口主体302的卡合部303向底座部530侧压紧，卡口模块300被固定在底座部530上。
图9A、图9B以及图9C是示意性地示出固定件102的倾斜面103以及背面活动件104的倾斜面105的剖视图。固定件102的倾斜面103向相对于第一方向20在底座部530侧形成锐角902的方向倾斜。背面活动件104的倾斜面105向相对于与第一方向20相反的第二方向30在前表面活动件106侧形成锐角912的方向倾斜。通过背面活动件104相对于固定件102沿第一方向20旋转，使得倾斜面105与倾斜面103接触之后，进而通过将倾斜面105在倾斜面103上滑动，背面活动件104以及前表面活动件106向底座部530侧移动。
如图9A所示，当背面活动件104相对于固定件102沿第一方向20旋转时，如图9B所示，倾斜面105与倾斜面103相接。此外，当背面活动件104相对于固定件102沿第一方向20旋转时，如图9C所示，倾斜面105在倾斜面103滑动。由此，背面活动件104在相对于固定件102沿第一方向20旋转的同时在朝向底座部530一侧的第三方向22上移动。由此，背面活动件104的卡合部107向底座部530侧压紧卡口模块300的卡合部303。由此，卡口模块300固定在底座部530上。
此外，在本实施例中，对固定件102和背面活动件104分别具有倾斜面的示例进行说明。不过，固定件102和背面活动件104中的至少一个具有倾斜面即可。当固定件102和背面活动件104中的一个具有倾斜面时，固定件102以及背面活动件104中的另一个可以在与倾斜面相对的位置具有突出部，该突出部在倾斜面滑动。
图10A至图10F示出了卡口模块300安装于中间卡口100，直至固定的情形。
图10A示出了卡口模块300布置在中间卡口100的开口内，且卡口模块300的卡合部303和中间卡口100的卡合部107尚未卡合的状态。即，图10A示出了用于将卡口模块300固定到中间卡口100的中间卡口100的旋转操作尚未进行的状态。图10B示出了图10A所示的A-A剖面中的卡口模块300以及中间卡口100的一部分。图10B示出了卡口主体302的卡合部303与前表面活动件106的卡合部107未卡合的状态。
图10C示出了操作操作件110，中间卡口100沿第一方向20旋转途中的情形。图10D示出了图10C所示的A-A剖面中的卡口模块300以及中间卡口100的一部分。图10D示出了卡口主体302的卡合部303与前表面活动件106的卡合部107卡合途中。在如图10D所示的 状态下，卡合部107和卡合部303之间、卡合部303和固定件102之间以及固定件102和背面活动件104之间，各自在中间卡口100的旋转轴的方向上在重合的部分未完全接触。
图10E示出了操作操作件110，直到卡口主体302的卡合部303和前表面活动件106的卡合部107至完全卡合的状态，中间卡口100在第一方向旋转的状态。图10F示出了图10E所示的A-A剖面中的卡口模块300以及中间卡口100的一部分。在如图10E所示，在中间卡口100固定在底座部530的状态下，卡合部107和卡合部303的各自的接触面、卡合部303和固定件102的各自的接触面以及固定件102和背面活动件104的各自的接触面在中间卡口100的旋转轴(光轴)方向上重合。即，卡合部107和卡合部303之间、卡合部303和固定件102之间以及固定件102和背面活动件104之间分别在中间卡口100的旋转轴的方向上重合的位置处存在没有间隙的部分。这样，当各自的接触面在中间卡口100的旋转轴的方向上重合的位置处无间隙地接触时，能够更有效地抑制卡口模块300相对于中间卡口100的晃动。进而在使中间卡口100的直径与卡口模块300的直径大小大致相同的同时，能够更有效地抑制卡口模块300相对于中间卡口100的晃动。
图11A是示出底座部530安装有构成中间卡口100的固定件102、以及构成卡口模块300的卡口主体302的状态的主视图。图11B是示出图11A所示的A-A剖面、B-B剖面、以及C-C剖面的图。
底座部530包括支撑图像传感器510的支撑部5311、5312、5313、5314、5315。图像传感器510通过由底座部530支撑，相对于底座部530固定在预定位置上。
相当于卡口主体302的卡口面和图像传感器510的摄像面之间的距离的法兰焦距514根据卡口规格而定，法兰焦距514的偏差会影响摄像装置500拍摄的图像的质量。因此，优选高精度地调整法兰焦距514。因此，在底座部530的前表面5301和固定件102的背面1021之间夹设理想厚度的间隔件130，实现与安装的可更换镜头10的卡口规格相应的法兰焦距514。通过将与安装的可更换镜头10的卡口规格相应的厚度的间隔件130夹设在底座部530的前表面5301和固定件102的背面1021之间，能够抑制摄像装置500拍摄的图像的质量降低。
图12示出了放大了设置于中间卡口100的操作件110的一部分的剖视图。
操作件110包括作为外壳的操作主体114、保持于操作主体114的按钮111以及限制件112。
在卡口模块300卡合到中间卡口100的状态下，限制件112限制中间卡口100朝与第一方向20相反的第二方向30旋转。按钮111切换限制件112限制中间卡口100朝第二方向30旋转的状态及不限制旋转的状态。
操作主体114包括沿着按下按钮111的方向的旋转轴113。按下按钮111的方向是卡口模块300从中间卡口100拆卸时使中间卡口100旋转的第二方向30。操作主体114保持限制件112，使其能够旋转轴113为中心旋转。当限制件112以旋转轴113为中心旋转时，限制件112的端部1121向中间卡口100的旋转中心的方向移动。
图13是底座部530开口531内的内周面的放大图。底座部530在收容中间卡口100的开口531内，具有距中间卡口100的旋转中心的距离为第一距离的内周面5321、距中间卡口100的旋转中心的距离长于第一距离的内周面5322以及连接内周面5321和内周面5322的边界面5323。通过底座部530的内周面5321和内周面5322的边界面5323，限制端部1121向第二方向30移动。
图14A是从正面观察到的按钮111以及限制件112的立体图。图14B是从背面观察到的按钮111以及限制件112的立体图。按钮111包括朝第二方向30按下的按压面1113以及按压面1113的背侧的突起部1112。限制件112包括突起部1112对应位置的倾斜面1122。按下按钮111的按压面1113，突起部1112沿倾斜面1122移动，限制件112以旋转轴113为中心旋转。当限制件112旋转时，端部1121向中间卡口100的旋转中心的方向移动。按钮111的突起部1112以及限制件112的倾斜面1122起到将按钮111的直线运动转换为限制件112的旋转运动的凸轮结构的作用。通过弹簧等弹性件116，限制件112的另一端1123被施压，以使端部1121朝中间卡口100的旋转中心方向的相反方向移动。
图15示出了图10A所示的B-B剖面中的操作件110的部分。图16示出了图10E所示的G-G剖面中的操作件110的部分。
图17A是从侧面观察到的摄像装置500的外观图。图17B示出了在卡口模块300的卡合部303和中间卡口100的卡合部107尚未卡合的状态下的图17A所示的M-M剖面。图17C示出了在卡口模块300的卡合部303和中间卡口100的卡合部107卡合的状态下的图17A所示的M-M剖面。图18是从固定件102的背面侧观察到的操作件110的图。操作件110包括限制背面活动件104以及前表面活动件106相对于固定件102旋转的爪部115。爪部115从前表面活动件106的外周侧面朝中间卡口100的旋转中心延伸，越过背面活动件104的背面直至固定件102的背面。固定件102的背面设置限制爪部115的移动的槽1023。
在卡口模块300的卡合部303和中间卡口100的卡合部107尚未卡合的状态下，弹性件116施加作用力，限制件112的端部1121接触底座部530的内周面5321。此外，如图17B所示，当爪部115到达固定件102的背面的槽1023的第一方向20的边界时，与槽1023的边缘接触，中间卡口100无法再朝第一方向20旋转。
通过弹性件116，端部1121在中间卡口100的远离旋转中心的方向上被施压，当中间卡口100朝第一方向20旋转时，端部1121与内周面5321接触并移动。然后，端部1121到达内周面5321和内周面5322之间的边界面5323，在边界面5323，端部1121通过弹性件116的作用力朝内周面5322侧移动。端部1121越过边界面5323到达至内周面5322，卡口模块300的卡合部303和中间卡口100的卡合部107卡合。
在卡口模块300和中间卡口100卡合的状态下，且在未按下按钮111的状态下，限制件112的端部1121与边界面5323接触，中间卡口100向第二方向30旋转受限。当按下按钮111时，限制件112以旋转轴113为中心旋转，端部1121朝中间卡口100的旋转中心的方向移动。由此，端部1121可以越过边界面5323朝第二方向30在内周面5321上移动。
用户安装中间卡口100到卡口模块300时，用指尖捏住操作件110的同时使中间卡口100朝第一方向20旋转。此时，即使未按下按钮111，限制件112的端部1121也能够沿底座部530的内周面5321移动。另一方面，用户从中间卡口100拆卸卡口模块300时，用指尖捏住操作件110的同时使中间卡口100朝第二方向30旋转。由于按钮111的按压面1113位于易于向第二方向30按下的位置，因此，当用户打算捏住操作件110的同时向第二方向30旋转中间卡口100，用户可以容易地用手指按下按压面1113。因此，用户可以容易地解除限制件112对朝向第二方向30旋转的限制，从而可以朝第二方向30旋转中间卡口100。
此处，用户打算捏住操作件110旋转中间卡口100时，用户最好按住摄像装置500避免摄像装置500移动。因此，如图19以及图20所示，壳体501可以在第一方向20以及第二方向30的两侧面分别包括辅助操作件110操作的凹部118。凹部118的形状可以和操作件110的旋钮部分的形状相同。操作件110在壳体501的上方移动，因此凹部118可以设置在壳体501的上方的两侧面。例如，用户用右手的拇指和食指按住两个凹部118的同时，用左手的拇指和食指捏住操作件110。然后，左手的拇指按下按钮111的按压面1113的同时，朝第二方向30旋转中间卡口100。由此，卡口模块300的卡合部303和中间卡口100的卡合部107的卡合得以解除，卡口模块300可以从中间卡口100上拆卸。另外，用户无需用手指捏住操作件110，可以仅用手指按下操作件110的按压面1113或与按压面1113相反一侧的面，从而朝第一方向20或第二方向30旋转中间卡口100。
如图20所示，卡口模块300包括具有锁止销360以及按钮352的按钮结构体350。锁止销360通过插入设于可更换镜头10的卡口的孔，对可更换镜头10的旋转进行锁止。按钮352与锁止销360机械连接，将锁止销360的插孔状态切换到未插孔状态。
图22是从前表面侧观察到的分解卡口模块300的按钮结构体350的部分的图。图23是从背面侧观察到的分解卡口模块300的按钮结构体350的部分的图。按钮352固定在L字形 的连接件354的一端。按钮352固定在从卡口模块300的外周缘附近开始沿中间卡口100的旋转轴的方向衍射到前表面侧的连接件354的一端。锁止销360固定在连接件354的另一端。锁止销360固定在从卡口模块300的外周缘附近开始沿着中间卡口100的旋转轴的方向延伸的连接件354的另一端。通过布置于按钮352的正下方的弹性件3521以及布置于锁止销360的正下方的弹性件3522，锁止销360被向从卡口主体302的前表面突出的方向施压。弹性件3521以及3522可以是弹簧等。当向卡口模块300安装可更换镜头10时，向可更换镜头10的卡口面按压锁止销360，成为不从卡口主体302的前表面突出的状态。
当可更换镜头10旋转至预定位置时，锁止销360移动至设于可更换镜头10的卡口面的孔的位置，通过弹性件的作用力，锁止销360从卡口主体302的前表面突出，而插入可更换镜头10的卡口面的孔。在该状态下，锁止销360成为屏障，可更换镜头10无法旋转。即，可更换镜头10无法从卡口模块300上拆卸。
当按下按钮352时，锁止销360不再从卡口主体302的前表面突出。由此，锁止销360无法构成屏障，可更换镜头10可以旋转。即，可更换镜头10可以从卡口模块300拆卸下来。
若卡口模块300不是从底座部530可装卸的结构，则中间卡口100不存在。在这种情况下，解除锁止销360的锁定的按钮352可以设置于底座部530。不过，本实施方式所涉及的卡口模块300是可装卸的，中间卡口100也存在，因此无法将按钮352设置在底座部530。
因此，在本实施方式中，按钮结构体350设置于卡口模块300。按钮结构体350设置于卡口模块300上，以便从卡口模块300的外周缘向外推出。如果将按钮352尽量设置于靠近中间卡口100的旋转中心附近，则可更换镜头10成为屏障，按钮352的操作难以进行。因此，如图21所示，按钮结构体350被设置成，在中间卡口100的旋转轴方向上与中间卡口100的外周缘1001重叠。
此外，为了使法兰焦距相对较短的卡口规格的可更换镜头10也能够安装在摄像装置500上，中间卡口100以及卡口模块300的光轴方向的厚度最好较小。因此，由于按钮结构体350的厚度的原因，中间卡口100以及卡口模块300的光轴方向的厚度最好不变大。因此，如图24以及图25所示，按钮结构体350被设置成，在中间卡口100的直径方向上与按钮结构体350的外周面1002重叠。按钮结构体350被设置成，按钮352的按压面与操作件110的前表面侧的面在中间卡口100的直径方向上重叠。
通过以此方式将按钮结构体350设置于卡口模块300，从而能够防止可更换镜头10成为屏障，按钮352不易按压的情况。此外，可以减小中间卡口100以及卡口模块300在光轴方向的厚度。
上述摄像装置500可以搭载于移动体上。摄像装置500可以搭载于如图26所示的无人驾驶航空器(UAV)上。UAV600可以包括UAV主体640、万向节620、多个摄像装置630，以及摄像装置500。万向节620及摄像装置500为摄像系统的一个示例。UAV600为由推进部推进的移动体的一个示例。移动体的概念是指除UAV之外，包括在空中移动的飞机等飞行体、在地面上移动的车辆、在水上移动的船舶等。
UAV主体640包括多个旋翼。多个旋翼为推进部的一个示例。UAV主体640通过控制多个旋翼的旋转而使UAV600飞行。UAV本体640采用例如4个旋翼，使UAV600飞行。旋翼的数量不限于四个。另外，UAV600也可以是没有旋翼的固定翼机。
摄像装置500是对包含在所期望的摄像范围内的被摄体进行摄像的摄像用相机。万向节620可旋转地支撑摄像装置500。万向节620为支撑机构的一个示例。例如，万向节620使用致动器以俯仰轴可旋转地支撑摄像装置500。万向节620使用致动器进一步分别以滚转轴和偏航轴为中心可旋转地支撑摄像装置500。万向节620可通过使摄像装置500以偏航轴、俯仰轴以及滚转轴中的至少1个为中心旋转，来改变摄像装置500的姿势。
多个摄像装置630是为了控制UAV600的飞行而对UAV600的周围进行拍摄的传感用相机。两个摄像装置630可以设置于UAV600的机头、即正面。并且，其它两个摄像装置630可以设置于UAV600的底面。正面侧的两个摄像装置630可以成对，起到所谓的立体相机的作用。底面侧的两个摄像装置630也可以成对，起到立体相机的作用。可以根据由多个摄像装置630所拍摄的图像来生成UAV600周围的三维空间数据。UAV600所包括的摄像装置630的数量不限于四个。UAV600包括至少一个摄像装置630即可。UAV600也可以在UAV600的机头、机尾、侧面、底面及顶面分别包括至少一个摄像装置630。摄像装置630中可设定的视角可大于摄像装置500中可设定的视角。摄像装置630也可以具有单焦点镜头或鱼眼镜头。
远程操作装置650与UAV600通信，对UAV600进行远程操作。远程操作装置650可以与UAV600进行无线通信。远程操作装置650向UAV600发送表示上升、下降、加速、减速、前进、后退、旋转等与UAV600的移动有关的各种指令的指示信息。指示信息包括例如使UAV600的高度上升的指示信息。指示信息可以表示UAV600应该位于的高度。UAV600进行移动，以位于从远程操作装置650接收的指示信息所表示的高度。指示信息可以包括使UAV600上升的上升指令。UAV600在接受上升指令的期间上升。在UAV600的高度已达到上限高度时，即使接受上升指令，也可以限制UAV600上升。
以上使用实施方式对本发明进行了说明，但是本发明的技术范围并不限于上述实施方式所描述的范围。对本领域普通技术人员来说，显然可对上述实施方式加以各种变更或改良。 从权利要求书的描述显而易见的是，加以了这样的变更或改良的方式都可包含在本发明的技术范围之内。
应该注意的是，权利要求书、说明书以及说明书附图中所示的装置、系统、程序以及方法中的动作、过程、步骤以及阶段等各项处理的执行顺序，只要没有特别明示“在...之前”、“事先”等，且只要前面处理的输出并不用在后面的处理中，则可以任意顺序实现。关于权利要求书、说明书以及说明书附图中的操作流程，为方便起见而使用“首先”、“接着”等进行了说明，但并不意味着必须按照这样的顺序实施。
