　また、図２に示すように、カメラ本体１の筐体５の前面側には、レンズユニット２が装着される部分に開口部５Ａが設けられ、この開口部５Ａには、レンズユニット２を保持するリング状のレンズマウント１０が配置されている。このレンズマウント１０は、レンズユニット２の光軸ＡＸ上に撮像ユニット４が配置されるように、レンズユニット２を保持する。これにより、レンズユニット２を通して結像された被写体像が撮像ユニット４により撮像されることとなる。 As shown in FIG. 2, an opening 5A is provided on the front side of the housing 5 of the camera body 1 in a portion where the lens unit 2 is mounted, and the lens unit 2 is held in the opening 5A. A ring-shaped lens mount 10 is disposed. The lens mount 10 holds the lens unit 2 so that the imaging unit 4 is disposed on the optical axis AX of the lens unit 2. As a result, the subject image formed through the lens unit 2 is picked up by the image pickup unit 4.

　図３に示すように、カメラ本体１の筐体５の開口部５Ａには、レンズマウント１０が配置され、そのレンズマウント１０と撮像ユニット４の間に配置されるように、マウントベース１１が固定されて配置されている。撮像ユニット４は、レンズユニット２側にシャッターユニット４Ａを有し、マウントベース１１は、シャッターユニット４Ａの前面側に固定されている。なお、マウントベース１１は、レンズマウント１０を支持するための支持部であるボス１２を有している。 As shown in FIG. 3, the lens mount 10 is disposed in the opening 5 </ b> A of the housing 5 of the camera body 1, and the mount base 11 is fixed so as to be disposed between the lens mount 10 and the imaging unit 4.

The mount base 11 has a boss 12 that is a support portion for supporting the lens mount 10.
　レンズマウント１０は、レンズユニット２が当接する当接部１０Ａと、当接部１０Ａの外周から延長させて当接部１０Ａに一体に設けたリング状の補強部１０Ｂとを有している。当接部１０Ａのレンズユニット２が当接する部分の反対側の部分は、ボス１２の先端部が当接しており、これによりレンズマウント１０の当接部１０Ａはマウントベース１１により支持されている。また、補強部１０Ｂは、レンズユニット２が装着される筐体５の開口部５Ａの周縁部に当接するように設けられ、補強部１０Ｂは、カメラ本体１の筐体５の内面側に固定部材であるビス１３により固定されている。これにより、レンズマウント１０は、マウントベース１１により支持される当接部１０Ａと、筐体５の開口部５Ａの周縁部に当接する補強部１０Ｂとの２点において保持されることとなり、筐体５の開口部５Ａに強固に配置することが可能となる。 The lens mount 10 has an abutting portion 10A with which the lens unit 2 abuts, and a ring-shaped reinforcing portion 10B provided integrally with the abutting portion 10A extending from the outer periphery of the abutting portion 10A. The tip of the boss 12 is in contact with the portion of the contact portion 10A opposite to the portion where the lens unit 2 is in contact, so that the contact portion 10A of the lens mount 10 is supported by the mount base 11. The reinforcing portion 10B is provided so as to come into contact with the peripheral edge of the opening 5A of the housing 5 to which the lens unit 2 is mounted, and the reinforcing portion 10B is a fixing member on the inner surface side of the housing 5 of the camera body 1. Are fixed by screws 13. Thus, the lens mount 10 is held at two points, that is, the contact portion 10A supported by the mount base 11 and the reinforcing portion 10B that contacts the peripheral edge portion of the opening 5A of the housing 5. 5 can be firmly arranged in the opening 5A.
　図５は、カメラ本体のレンズマウント部分の概略断面構造の他の例を示す断面図である。図６は、本技術の一実施の形態によるデジタルカメラにおいて、レンズマウントの他の例を示す斜視図である。 FIG. 5 is a cross-sectional view showing another example of the schematic cross-sectional structure of the lens mount portion of the camera body. FIG. 6 is a perspective view illustrating another example of the lens mount in the digital camera according to the embodiment of the present technology.
　この図５、図６に示す例は、上記図３、図４に示す例と同様に、レンズマウント１０は、レンズユニット２が当接する当接部１０Ａと、当接部１０Ａの外周から延長させて当接部１０Ａに一体に設けたリング状の補強部１０Ｂとを有している。そして、補強部１０Ｂは、筐体５の開口部５Ａの周縁部の形状に合致する形状としたものである。これにより、補強部１０Ｂ全体が、筐体５の開口部５Ａの周縁部に当接することとなり、より強固にレンズマウント１０を保持することが可能となる。なお、補強部１０Ｂは、先端部において、カメラ本体１の筐体５の内面側に固定部材であるビス１３により固定されている。 In the examples shown in FIGS. 5 and 6, the lens mount 10 is extended from the contact portion 10A with which the lens unit 2 contacts and the outer periphery of the contact portion 10A, as in the examples shown in FIGS. And a ring-shaped reinforcing portion 10B provided integrally with the abutting portion 10A. The reinforcing portion 10 </ b> B has a shape that matches the shape of the peripheral edge of the opening 5 </ b> A of the housing 5. Thereby, the whole reinforcement part 10B will contact | abut to the peripheral part of opening 5A of the housing | casing 5, and it becomes possible to hold | maintain the lens mount 10 more firmly. The reinforcing portion 10B is fixed to the inner surface side of the housing 5 of the camera body 1 with a screw 13 as a fixing member at the distal end portion.
　図７は、本技術の一実施の形態によるデジタルカメラにおいて、レンズマウントの他の例を示す斜視図である。この図７に示す例においては、レンズマウント１０の補強部１０Ｂは、レンズユニット２が当接する当接部１０Ａの外周に、全周にわたって設けるのではなく、上部の一部に補強部１０Ｂを設けたものである。 FIG. 7 is a perspective view showing another example of a lens mount in a digital camera according to an embodiment of the present technology. In the example shown in FIG. 7, the reinforcing portion 10B of the lens mount 10 is not provided over the entire circumference of the abutting portion 10A with which the lens unit 2 abuts, but the reinforcing portion 10B is provided in a part of the upper portion. It is a thing.
　図８は、レンズ交換式のデジタルカメラにおいて発生しやすい落下姿勢を示す説明図である。図８に示すように、大型のレンズユニット２を装着した際は、重心が前方へ移動しているため、落下時にレンズユニット２の下部から床面に衝突する確率が高い傾向にある。このため、デジタルカメラを落下させてしまった場合、レンズマウント１０の上部の領域Ｘに応力集中が発生し、変形によるレンズ位置ずれが発生しやすくなる。 FIG. 8 is an explanatory diagram showing a drop posture that is likely to occur in an interchangeable lens digital camera. As shown in FIG. 8, when the large lens unit 2 is mounted, the center of gravity moves forward, so that the probability of colliding with the floor surface from the lower part of the lens unit 2 when falling is high. For this reason, when the digital camera is dropped, stress concentration occurs in the area X on the upper part of the lens mount 10 and the lens position shift due to deformation is likely to occur.
　図７に示す例においては、デジタルカメラを落下させてしまった場合に、応力集中が発生しやすいレンズマウント１０の上部のみに補強部１０Ｂを設けたものである。これにより、この場合も、レンズマウント１０は、マウントベース１１により支持される当接部１０Ａと、応力集中が発生しやすい部分に設けた補強部１０Ｂとの２点において保持されることとなり、筐体５の開口部５Ａに強固に配置することが可能となる。また、補強部１０Ｂが効果の大きい領域のみに設けることにより、レンズマウント１０の形状を簡素化し、軽量化できるという利点がある。 In the example shown in FIG. 7, the reinforcing portion 10B is provided only on the upper portion of the lens mount 10 where stress concentration is likely to occur when the digital camera is dropped. Accordingly, in this case as well, the lens mount 10 is held at two points, that is, the abutting portion 10A supported by the mount base 11 and the reinforcing portion 10B provided at a portion where stress concentration is likely to occur. It becomes possible to arrange firmly in the opening 5A of the body 5. Further, by providing the reinforcing portion 10B only in a region where the effect is large, there is an advantage that the shape of the lens mount 10 can be simplified and reduced in weight.
　以上のように、本技術による撮像装置は、撮像素子を有する撮像ユニット４を筐体５内に収容することにより構成したカメラ本体１と、カメラ本体１に着脱可能に装着され、撮像素子に被写体像を形成するための光学系を構成するレンズユニット２とを有する。そして、レンズユニット２が装着されるカメラ本体１の筐体５の開口部５Ａに配置され、レンズユニット２を保持するリング状のレンズマウント１０と、カメラ本体１の筐体５内において、レンズマウント１０と撮像ユニット４の間に配置され、レンズマウント１０を支持するように構成したマウントベース１１とを有する。さらに、レンズマウント１０は、レンズユニット２が当接するとともに、マウントベース１１により支持された当接部１０Ａと、レンズユニット２が装着される筐体５の開口部５Ａの周縁部に当接するように当接部１０Ａの外周から延長させて当接部１０Ａに一体に設けた補強部１０Ｂとを備えている。これにより、レンズマウント１０は、マウントベース１１により支持される当接部１０Ａと、筐体５の開口部５Ａの周縁部に当接する補強部１０Ｂとにおいて保持されることとなり、筐体５の開口部５Ａに強固に配置することが可能となる。 As described above, the imaging apparatus according to the present technology includes the camera body 1 configured by housing the imaging unit 4 having the imaging element in the housing 5, and is detachably attached to the camera body 1. And a lens unit 2 constituting an optical system for forming an image. Then, the lens mount 2 is disposed in the opening 5A of the housing 5 of the camera body 1 to which the lens unit 2 is mounted, and holds the lens unit 2, and the lens mount in the housing 5 of the camera body 1. 10 and an imaging unit 4, and a mount base 11 configured to support the lens mount 10. Further, the lens mount 10 is in contact with the lens unit 2, and is in contact with the contact portion 10 </ b> A supported by the mount base 11 and the peripheral portion of the opening 5 </ b> A of the housing 5 to which the lens unit 2 is mounted. And a reinforcing portion 10B provided integrally with the abutting portion 10A so as to extend from the outer periphery of the abutting portion 10A. Accordingly, the lens mount 10 is held by the abutting portion 10A supported by the mount base 11 and the reinforcing portion 10B that abuts on the peripheral edge portion of the opening 5A of the housing 5. It becomes possible to arrange firmly in the part 5A.
　特に、撮像装置を落下させてしまったとき等、レンズユニット２に外部から機械的な大きな力が加えられた場合、荷重がレンズマウント１０とボス１２にかかり、ボス１２やマウントベース１１の変形がしやすくなり、レンズの位置ずれが生じやすいが、本技術によれば、レンズマウント１０からボス１２を介してマウントベース１１に伝わる力を低減させることができ、レンズの位置ずれを抑制することができる。 In particular, when a large mechanical force is applied to the lens unit 2 from the outside, such as when the image pickup apparatus is dropped, the load is applied to the lens mount 10 and the boss 12, and the boss 12 and the mount base 11 are deformed. However, according to the present technology, the force transmitted from the lens mount 10 to the mount base 11 via the boss 12 can be reduced, and the lens position shift can be suppressed. it can.
