In order to solve the above problems, the device according to the present invention is an imaging apparatus with a built-in wireless communication unit that performs wireless communication,-out guide the light incident on the imaging device to an eyepiece optical system, the light incident An optical member having a reflecting surface that reflects toward the eyepiece optical system, a plurality of exterior members that cover the optical member, and a substrate fixing member that fixes a substrate on which the antenna unit of the wireless communication unit is mounted. The wireless communication unit is disposed in a space formed between the optical member and the exterior member, and the ground portion of the wireless communication unit is substantially the same as the reflecting surface of the optical member. is connected to the substrate fixing member by the antenna portion and the pair oriented position so as to be disposed parallel to, the substrate fixing member, the imaging device mounted on the member for holding the optical member Characterized in that it is ground portion electrically connected.
次に、図１および図６を参照して、カメラボディ１００の外装構成について説明する。
カメラ動作に対して電磁波の影響を低減するために、外装部材に電磁遮蔽効果を持たせる方法が知られている。外装材料に金属材料、または金属繊維やカーボン繊維を混合した導電性樹脂材料を用いる方法と、非導電性の合成樹脂材料の表面に導電性被膜（導電塗装やイオンプレーティング等による被膜）を施す方法がある。
本実施形態では、第１外装部材である上面外装カバー１０１と第２外装部材である正面外装カバー１０２が、ペンタプリズム５１の第２反射面５１ｂの周辺で分割された構成を有する。無線基板４１は、前面側から見た場合、ほぼ基板全体が正面外装カバー１０２に覆われた状態である。よって、無線基板４１のアンテナ部４２が導電性材料で周囲を覆われて、無線通信用の電波を放射できないと、通信に支障を来たす状態となる。そのため、正面外装カバー１０２は電気抵抗率の高い材料で成形されている。例えば、上面外装カバー１０１と背面外装カバー１１１はカーボン繊維混合樹脂、つまりカーボン繊維を混合した樹脂材料で成形されている。一方、正面外装カバー１０２は上面外装カバー１０１や背面外装カバー１１１に比べて電気抵抗率の高いガラス繊維を混合した樹脂材料で成形されている。但し、これに限定されるものではなく、上面外装カバー１０１と背面外装カバー１１１を金属材料で形成してもよいし、ガラス繊維混合樹脂に導電性被膜を施した材料であってもよい。また、正面外装カバー１０２については、無線通信が可能な程度に電気抵抗率が高い材料であれば適用可能である。
Next, an exterior configuration of the camera body 100 will be described with reference to FIGS. 1 and 6.
In order to reduce the influence of electromagnetic waves on the camera operation, a method of giving an electromagnetic shielding effect to the exterior member is known. A method using a metal material or a conductive resin material mixed with metal fiber or carbon fiber as the exterior material, and a conductive film (coating by conductive coating or ion plating) on the surface of the non-conductive synthetic resin material There is a way.
In the present embodiment, a top exterior cover 101 that is a first exterior member and a front exterior cover 102 that is a second exterior member have a configuration that is divided around the second reflection surface 51 b of the pentaprism 51. When viewed from the front side, the wireless substrate 41 is in a state where almost the entire substrate is covered with the front exterior cover 102. Therefore, if the antenna portion 42 of the wireless substrate 41 is covered with a conductive material and radio waves for wireless communication cannot be radiated, communication is hindered. Therefore, the front exterior cover 102 is formed of a material having a high electrical resistivity. For example, the top exterior cover 101 and the back exterior cover 111 are formed of a carbon fiber mixed resin, that is, a resin material in which carbon fibers are mixed. On the other hand, the front exterior cover 102 is formed of a resin material in which glass fibers having a higher electrical resistivity than the upper exterior cover 101 and the rear exterior cover 111 are mixed. However, the present invention is not limited to this, and the upper exterior cover 101 and the rear exterior cover 111 may be formed of a metal material, or may be a material obtained by applying a conductive coating to a glass fiber mixed resin. As for the exterior front cover 102, the electrical resistivity to an extent capable of wireless communication is applicable to any high material.
次に図６を参照して、正面外装カバー１０２の内面に形成する導電性被膜について説明する。図６は正面外装カバー１０２をカメラボディ１００の内側から見た状態を示す。以下、導電性被膜の形成範囲を説明する。表面処理により形成される導電性被膜については、導電性塗料やイオンプレーティングによる被膜、あるいはその他の導電性被膜でもよいが、本実施形態では導電性塗料を例にして説明する。
正面外装カバー１０２の内面には導電性被膜を形成した範囲と、領域３００（斜線部参照）に示すように、導電性の塗装膜または蒸着膜を形成していない領域がある。領域３００は、無線基板４１のアンテナ部４２と対向する領域およびその周辺域を含み、導電性塗装膜または蒸着膜が施されていない領域である。この領域３００は、アンテナ部４２に対向する面積よりも広い範囲となるように設定されている。正面外装カバー１０２の内面に導電塗装を施す場合、領域３００にはマスキング処理が行われ、導電性塗料が付着しないように処置される。よって、領域３００は無線通信可能な程度に電気抵抗率が高い領域となっている。また、正面外装カバー１０２の内面のうちで領域３００以外の範囲には、ほぼ全域に亘って導電塗装が施されるため、正面外装カバー１０２は電磁波の遮蔽機能を有する。
Next, the conductive film formed on the inner surface of the front exterior cover 102 will be described with reference to FIG. FIG. 6 shows the front exterior cover 102 as viewed from the inside of the camera body 100. Hereinafter, the formation range of the conductive film will be described. The conductive coating formed by the surface treatment may be a conductive coating, a coating by ion plating, or other conductive coating, but in this embodiment, the conductive coating will be described as an example.
On the inner surface of the front exterior cover 102, there are a region where a conductive coating is formed and a region where a conductive coating film or vapor deposition film is not formed, as shown in a region 300 (see the hatched portion). The region 300 includes a region facing the antenna portion 42 of the wireless substrate 41 and its peripheral region, and is a region where no conductive coating film or vapor deposition film is applied. This region 300 is set to be wider than the area facing the antenna unit 42. When the conductive coating is applied to the inner surface of the front exterior cover 102, the region 300 is subjected to a masking process to prevent the conductive paint from adhering. Therefore, region 300 is the electrical resistivity is in the region of high enough to be wireless communication. In addition, since the conductive coating is applied to almost the entire area of the inner surface of the front exterior cover 102 other than the region 300, the front exterior cover 102 has an electromagnetic wave shielding function.
正面外装カバー１０２の内面の複数個所に設けたビス留め部３０１ａ，３０１ｂは、上面外装カバー１０１と共にミラーボックス５３に締結固定される際に、上面外装カバー１０１と平面で密着する取り付け部である。複数のビス留め部３０１ａ，３０１ｂには導電塗装が施されているため、導電性樹脂で成形した上面外装カバー１０１と電気的に接続される。無線基板４１のアンテナ部４２は、ビス留め部３０１ａと３０１ｂとの間に挟まれた領域に配置され、アンテナ部４２の上側の周辺域は上面外装カバー１０１で覆われる。このため、アンテナ部４２は電気的に接続された外装部材で囲まれるが、正面外装カバー１０２のうち、アンテナ部４２に対向する領域３００は電気抵抗率が相対的に高い領域である。また、アンテナ部４２は接眼光学系の光軸１ａに対応する部分から離隔して、無線基板４１の右端寄りの位置に設けられている。よって、アンテナ部４２はレンズ着脱マウント６０（図２参照）からカメラの高さ方向において極力離れて位置する。無線基板４１のアンテナ部４２を導電部材であるレンズ着脱マウント６０から極力離して配置することができるので、送受信時の電波はレンズ着脱マウント６０の影響を受け難くなる。
Screw fastening portions 301 a and 301 b provided at a plurality of positions on the inner surface of the front exterior cover 102 are attachment portions that are in close contact with the upper surface exterior cover 101 in a plane when fastened to the mirror box 53 together with the upper surface exterior cover 101. Since the plurality of screw fastening portions 301a and 301b are subjected to conductive coating, they are electrically connected to the upper surface outer cover 101 formed of a conductive resin. The antenna portion 42 of the wireless substrate 41 is disposed in a region sandwiched between the screw fastening portions 301 a and 301 b, and the upper peripheral region of the antenna portion 42 is covered with the top surface exterior cover 101. Therefore, the antenna unit 42 is surrounded by the external member which is electrically connected, among the front outer cover 102, region 300 opposed to the antenna element 42 is a high electrical resistivity is relatively regions. Further, the antenna unit 42 is provided at a position near the right end of the wireless substrate 41, separated from a portion corresponding to the optical axis 1 a of the eyepiece optical system. Therefore, the antenna unit 42 is located as far as possible from the lens mount 60 (see FIG. 2) in the height direction of the camera. Since the antenna portion 42 of the wireless substrate 41 can be arranged as far as possible from the lens attaching / detaching mount 60 that is a conductive member, radio waves during transmission / reception are hardly affected by the lens attaching / detaching mount 60.
