　図３は、比較例１のカメラ２０１の構成を説明する概略図である。
　図４は、比較例２のカメラ３０１の構成を説明する概略図である。
　比較例１のカメラ２０１は、レンズ鏡筒２１０に遮蔽板を備えてなく、また、マウント側カバー２１２の全体が樹脂で形成されている点で本実施形態のカメラ１と相違する。
　レンズ鏡筒２１０は、カメラ筐体２０２から電力が供給されると、電子基板２１３のインダクタ２１３ａから電磁波が発生する。その発生した電磁波の一部Ｍ１は、図３に示すように、インダクタ２１３ａの後部（Ｘ１側）からマウント側カバー２１２を透過して撮像素子３に向かう。また、その他の電磁波の一部Ｍ２は、インダクタ２１３ａの側部（Ｚ２側）からマウント側カバー２１２を透過して撮像素子３に向かう。
　そのため、比較例１のカメラ２０１は、撮像素子２０３がこれらの電磁波の影響による電気ノイズによって、撮影した被写体像の品質が劣化する場合がある。 Next, the flow of electromagnetic waves generated from the inductor 13a of the electronic substrate 13 will be described.
FIG. 3 is a schematic diagram illustrating the configuration of the camera 201 of the first comparative example.
FIG. 4 is a schematic diagram illustrating the configuration of the camera 301 of the second comparative example.
The camera 201 of the comparative example 1 is different from the camera 1 of the present embodiment in that the lens barrel 210 is not provided with a shielding plate and the entire mount side cover 212 is made of resin.
The lens barrel 210 generates electromagnetic waves from the inductor 213 a of the electronic substrate 213 when power is supplied from the camera housing 202. A part M1 of the generated electromagnetic wave passes through the mount side cover 212 from the rear part (X1 side) of the inductor 213a and travels toward the image sensor 3 as shown in FIG. Further, a part M2 of other electromagnetic waves passes through the mount-side cover 212 from the side portion (Z2 side) of the inductor 213a and travels toward the image sensor 3.
For this reason, in the camera 201 of Comparative Example 1, the quality of the captured subject image may be deteriorated by the electrical noise caused by the influence of these electromagnetic waves on the image sensor 203.
　比較例２のカメラ３０１は、レンズ鏡筒３１０に遮蔽板３１４を備えているが、マウント側カバー３１２全体が樹脂で形成されている点で本実施形態のカメラ１と相違する。
　図４に示すように、インダクタ３１３ａの後部（Ｘ１側）から発生する電磁波は、遮蔽板３１４によって遮蔽されるが、インダクタ３１３ａの側部（Ｚ２側）から発生する電磁波の一部Ｍ３は、樹脂により形成されるマウント側カバー３１２を透過して、撮像素子３０３へ到達してしまう。そのため、比較例２のカメラ３０１は、撮像素子３０３がこの電磁波の影響を受けることとなり、比較例１のカメラ２０１の場合よりも影響が小さいが、撮影した被写体像の品質が劣化する場合がある。 The camera 301 of the comparative example 2 includes the shielding plate 314 in the lens barrel 310, but is different from the camera 1 of the present embodiment in that the entire mount side cover 312 is formed of resin.
As shown in FIG. 4, the electromagnetic wave generated from the rear part (X1 side) of the inductor 313a is shielded by the shielding plate 314, but a part M3 of the electromagnetic wave generated from the side part (Z2 side) of the inductor 313a is resin. Through the mount side cover 312 formed by the above, the image sensor 303 is reached. Therefore, in the camera 301 of the comparative example 2, the imaging element 303 is affected by this electromagnetic wave, and although the influence is smaller than the case of the camera 201 of the comparative example 1, the quality of the captured subject image may be deteriorated. .
　これに対して、本実施形態のレンズ鏡筒１０は、図１に示すように、インダクタ１３ａの後部（Ｘ１側）に、遮蔽板１４が配置され、また、インダクタ１３ａの側部（Ｚ２側）に、金属により形成されたマウント側カバー１２の筒部１２１が配置されている。
　そのため、インダクタ１３ａの後部（Ｘ１側）から撮像素子３に向かう電磁波は、遮蔽板１４によって遮蔽されることとなり、インダクタ１３ａの側部（Ｚ２側）から撮像素子３に向かう電磁波は、金属により形成されたマウント側カバー１２の筒部１２１によって遮蔽される。
　この構成により、本実施形態のカメラ１は、インダクタ１３ａから発生し、撮像素子３に向かう電磁波のほとんどを遮蔽することができ、カメラ１の撮像素子３は、高品質な被写体像を取得することができる。 On the other hand, in the lens barrel 10 of the present embodiment, as shown in FIG. 1, the shielding plate 14 is disposed at the rear part (X1 side) of the inductor 13a, and the side part (Z2 side) of the inductor 13a. Further, the cylindrical portion 121 of the mount side cover 12 formed of metal is disposed.
Therefore, an electromagnetic wave directed from the rear part (X1 side) of the inductor 13a toward the image sensor 3 is shielded by the shielding plate 14, and an electromagnetic wave directed from the side part (Z2 side) of the inductor 13a to the image sensor 3 is formed of metal. The mount side cover 12 is shielded by the cylindrical portion 121.
With this configuration, the camera 1 of the present embodiment can shield most of the electromagnetic waves generated from the inductor 13a and directed to the image sensor 3, and the image sensor 3 of the camera 1 acquires a high-quality subject image. Can do.
　以上説明したように、本実施形態のレンズ鏡筒１０、カメラ１には以下のような効果がある。
（１）レンズ鏡筒１０は、インダクタ１３ａに対向する位置にマウント側カバー１２が配置され、マウント側カバー１２が金属から形成される筒部１２１と、樹脂から形成される平板部１２２とから構成されているので、マウント側カバー１２の筒部１２１によって、インダクタ１３ａの側部（Ｚ２側）から発生する電磁波を遮断することができる。これにより、インダクタ１３ａから発生する電磁波の影響により、カメラ１の撮像素子３によって撮影される画像品質の劣化を抑制することができる。
　また、マウント側カバー１２の一部である筒部１２１を金属で形成することによって電磁波を遮蔽しているので、インダクタ１３ａの周囲の空間が非常に狭い場合であっても、効率よく電磁波を遮断することができる。 As described above, the lens barrel 10 and the camera 1 of the present embodiment have the following effects.
(1) The lens barrel 10 includes a mount-side cover 12 disposed at a position facing the inductor 13a, and the mount-side cover 12 includes a cylindrical portion 121 formed of metal and a flat plate portion 122 formed of resin. Thus, the cylindrical portion 121 of the mount side cover 12 can block electromagnetic waves generated from the side portion (Z2 side) of the inductor 13a. Thereby, deterioration of the image quality image | photographed with the image pick-up element 3 of the camera 1 can be suppressed under the influence of the electromagnetic waves which generate | occur | produce from the inductor 13a.
In addition, since the cylindrical portion 121 that is a part of the mount-side cover 12 is made of metal, the electromagnetic wave is shielded. Therefore, even when the space around the inductor 13a is very narrow, the electromagnetic wave is efficiently blocked. can do.
（２）マウント側カバー１２は、複雑な形状を有し、金属加工が困難な平板部１２２が樹脂の成形によって形成され、金属加工が容易な筒部１２１のみを金属の切削加工等によって形成されているので、マウント側カバー１２を容易に、かつ、安価に製作することができる。仮に、マウント側カバー１２の全体を金属で形成するとした場合、平板部１２２の加工に高精度な金属加工を必要とし、製作時間及び製作コストを大幅に増加させることになるが、本発明のレンズ鏡筒１０は、このような問題を回避することができる。 (2) The mount-side cover 12 has a complicated shape, the flat plate portion 122 that is difficult to be metal-worked is formed by resin molding, and only the cylindrical portion 121 that is easy to metal-work is formed by metal cutting or the like. Therefore, the mount side cover 12 can be manufactured easily and inexpensively. If the entire mount-side cover 12 is made of metal, high-precision metal processing is required for processing the flat plate portion 122, which greatly increases the manufacturing time and manufacturing cost. The lens barrel 10 can avoid such a problem.
（３）レンズ鏡筒１０は、電磁波を遮断する遮蔽板１４を、マウント側カバー１２の平板部１２２と、インダクタ１３ａとの間に配置しているので、インダクタ１３ａの後部（Ｘ１側）から発生し、平板部１２２を透過する電磁波を遮断することができる。これにより、レンズ鏡筒１０は、遮蔽板１４と、マウント側カバー１２の筒部１２１とによって、インダクタ１３ａから発生し、撮像素子３に向かう電磁波を遮断することができ、カメラ１の撮像素子３は、被写体像を高精度に撮影することができる。 (3) Since the lens barrel 10 has the shielding plate 14 for blocking electromagnetic waves disposed between the flat plate portion 122 of the mount side cover 12 and the inductor 13a, the lens barrel 10 is generated from the rear portion (X1 side) of the inductor 13a. In addition, the electromagnetic wave transmitted through the flat plate portion 122 can be blocked. Thereby, the lens barrel 10 can block the electromagnetic wave generated from the inductor 13a and directed to the image pickup device 3 by the shielding plate 14 and the tube portion 121 of the mount side cover 12, and the image pickup device 3 of the camera 1 can be blocked. Can shoot a subject image with high accuracy.
