　また、本発明の無線通信方法は、第１の無線通信装置のアンテナに、芯線と、前記芯線と対をなす網状線とを備えた同軸ケーブルにより形成された電線の一端部を非接触状態で配置する段階と、前記電線の他端部を、第２の無線通信装置のアンテナに非接触状態で配置する段階と、前記芯線の一端部と前記第１の無線通信装置のアンテナとの間で、無線信号が伝搬し、前記芯線の他端部と前記第２の無線通信装置のアンテナとの間で、前記無線信号が伝搬して、前記第１の無線通信装置と前記第２の無線通信装置とを、前記電線を介在させて通信する段階とを含むことを特徴とする。 In the wireless communication method of the present invention, an end of an electric wire formed by a coaxial cable having a core wire and a mesh wire paired with the core wire is arranged in a non-contact state on the antenna of the first wireless communication device. Placing the other end of the wire in a non-contact state with the antenna of the second wireless communication device, and between the one end of the core wire and the antenna of the first wireless communication device. The radio signal propagates, and the radio signal propagates between the other end of the core wire and the antenna of the second radio communication device, and the first radio communication device and the second radio communication. And communicating with the apparatus through the electric wire.
　本発明によれば、第１の無線通信装置のアンテナと、第２の無線通信装置のアンテナとの間に、非接触状態で電線の両端部を配置して、電線を介在させて第１の無線通信装置と第２の無線通信装置とが通信することで、第１の無線通信装置と第２の無線通信装置との間の無線通信は、電線を通して行うことができるので、他の無線信号に妨害されずに通信を行うことができる。また、電線が、同軸ケーブルにより形成されているため、網状線を、通信路となる芯線の保護シールドとして機能させることができる。 According to the present invention, both ends of the electric wire are arranged in a non-contact state between the antenna of the first radio communication device and the antenna of the second radio communication device, and the electric wire is interposed between the first radio communication device and the first radio communication device. Since the wireless communication device and the second wireless communication device communicate with each other, wireless communication between the first wireless communication device and the second wireless communication device can be performed through the electric wire. Communication can be performed without interruption. Moreover, since the electric wire is formed of a coaxial cable, the mesh wire can function as a protective shield for the core wire serving as a communication path.
　ここで、アンテナに非接触とは、電線の一端部または他端部が直接アンテナに接続されていないことを意味している。従って、電線の一端部または他端部がアンテナに直接接触していなければ、第１の無線通信装置や第２の無線通信装置の筐体や基板、他の部品に接続している場合も、アンテナに非接触状態として含まれる。 Here, non-contact with the antenna means that one end or the other end of the electric wire is not directly connected to the antenna. Therefore, if one end or the other end of the electric wire is not in direct contact with the antenna, the case or the substrate of the first wireless communication device or the second wireless communication device may be connected to other parts, It is included in the antenna as a non-contact state.
　前記電線が伝搬する無線信号は、ＷｉＦｉまたはＢＬＵＥＴＯＯＴＨによるものとすると、同軸ケーブルでの伝送において、ＷｉＦｉまたはＢＬＵＥＴＯＯＴＨが使用するＵＨＦ帯、ＳＨＦ帯などの高周波領域における信号の減衰を抑えることができる。 Suppose that the wireless signal propagated by the wire is based on WiFi or BLUETOOTH, it is possible to suppress signal attenuation in a high-frequency region such as UHF band and SHF band used by WiFi or BLUETOOTH in transmission via a coaxial cable.
　前記第１の無線通信装置は、前記第２の無線通信装置から前記電線を介在させて送信された無線信号により操作されるカメラであることが望ましい。
　第１の無線通信装置がカメラであると、第２の無線通信装置からカメラを操作することができる。 The first wireless communication device is preferably a camera operated by a wireless signal transmitted from the second wireless communication device through the electric wire.

Since the camera is positioned at the distal end portion of the rod-like support member, it is possible to perform shooting from a high place or a low place and a wide range of shooting from the position of the operator.
　前記棒状支持用部材には、前記電線を前記棒状支持用部材に沿って配線する保持部材が所定間隔ごとに配置されていると、保持部材に電線を保持させることで、電線を棒状支持用部材に沿って配線することができるため、撮影者が撮影するときに棒状支持用部材を操作するときに電線が邪魔にならない。 If the holding member for wiring the electric wire along the rod-like support member is arranged at predetermined intervals on the rod-like support member, the electric wire is held by the holding member to hold the electric wire to the rod-like support member. Therefore, when the photographer takes a picture, the wire does not get in the way when operating the rod-like support member.

Further, the camera housed in the housing can be attached to the tip of the rod-like support member.
　前記ハウジングが、電磁波シールドを備えていると、カメラに他の無線通信装置からの無線信号が到達し難くなるため、更に、カメラと第２の無線通信装置との間の無線通信に、邪魔な他の無線信号が混入することを抑止することができる。 If the housing is provided with an electromagnetic wave shield, it is difficult for wireless signals from other wireless communication devices to reach the camera, which is further disturbing wireless communication between the camera and the second wireless communication device.

The electric wire is propagated as a part of the communication path, can reach the camera from one end of the electric wire in a watertight state and in a non-contact state with the camera. Further, the radio signal from the camera reaches the second radio communication device by propagation in the opposite direction.

　前記電線の一端部には、前記電線の導線部を収納して、水密状態で、前記ハウジングの外側面に接続する接続用部材が設けられていると、電線の一端部を水密状態でハウジングの外側面に設けることができる。電線の一端部は、ハウジングの外側面に配置されるため、既存のハウジングであっても、容易に、ハウジングに設けることができる。 One end of the electric wire is provided with a connecting member that houses the conductor portion of the electric wire and is connected in a watertight manner to the outer surface of the housing. It can be provided on the outer surface. Since one end of the electric wire is disposed on the outer surface of the housing, even an existing housing can be easily provided on the housing.
　前記電線の一端部が、前記ハウジングを貫通して、前記ハウジング内の空間に突出していると、電線の一端部からの無線信号を、水密状態のハウジング内の空間に放出されることができる。 When one end of the electric wire penetrates the housing and protrudes into the space in the housing, a radio signal from the one end of the electric wire can be emitted into the space in the watertight housing.
　前記電線の一端部が、前記ハウジングに埋入されていると、ハウジングに埋入されて水密状態となった電線の一端部からの無線信号を、ハウジングを介してハウジング内の空間に放出されることができる。 When one end of the electric wire is embedded in the housing, a radio signal from the one end of the electric wire embedded in the housing and brought into a watertight state is released to the space in the housing through the housing. be able to.
　前記他端部に、前記第２の無線通信装置が有する第１コネクタに嵌合する第２コネクタが設けられていることが望ましい。電線の他端部に第２の無線通信装置が有する第１コネクタに嵌合する第２コネクタが設けられていると、電線の他端部を第２の無線通信装置に接続することができるため、電線を安定させることができる。 It is desirable that a second connector that fits into the first connector of the second wireless communication device is provided at the other end. If the second connector that fits into the first connector of the second wireless communication device is provided at the other end of the electric wire, the other end of the electric wire can be connected to the second wireless communication device. The electric wire can be stabilized.
　本発明は、第１の無線通信装置と第２の無線通信装置との間の無線通信が、電線を通して行うことができるので、他の無線信号に妨害されずに通信を行うことができるため、良好な通信環境を確保することができる。 In the present invention, since wireless communication between the first wireless communication device and the second wireless communication device can be performed through an electric wire, communication can be performed without being disturbed by other wireless signals.

（実施の形態１）
　本発明の実施の形態１に係る無線通信用補助具を図面に基づいて説明する。
　図１に示す無線通信用補助具１は、同軸ケーブルである電線２００の一端部２０１がカメラ２０（第１の無線通信装置）に近接して配置されていると共に、電線２００の他端部２０２がスマートフォン３０（第２の無線通信装置）に近接して配置されている。
　電線２００の両端部（一端部２０１，他端部２０２）が、それぞれカメラ２０とスマートフォン３０に近接していることにより、カメラ２０のアンテナ（図示せず）に対して非接触の状態であり、スマートフォン３０のアンテナ（図示せず）に対して非接触の状態である。 (Embodiment 1)
A wireless communication aid according to Embodiment 1 of the present invention will be described with reference to the drawings.
In the wireless communication auxiliary tool 1 shown in FIG. 1, one end 201 of the electric wire 200 that is a coaxial cable is disposed in the vicinity of the camera 20 (first wireless communication device), and the other end 202 of the electric wire 200. Are arranged close to the smartphone 30 (second wireless communication device).
Since both ends (one end 201 and the other end 202) of the electric wire 200 are close to the camera 20 and the smartphone 30, respectively, they are in a non-contact state with respect to the antenna (not shown) of the camera 20. It is a non-contact state with respect to the antenna (not shown) of the smart phone 30.
　カメラ２０は、無線信号により操作される機能を有し、静止画や動画が撮影できるデジタルカメラである。無線信号は、例えば、ＷｉＦｉやＢＬＵＥＴＯＯＴＨ、または他の無線通信方式とすることができる。
　スマートフォン３０は、カメラ２０を無線操作するためのアプリケーションソフトがインストールされている。スマートフォン３０は、カメラ２０を無線信号により遠隔装置ためのアンテナ（図示せず）が内蔵されている。 The camera 20 is a digital camera that has a function operated by a wireless signal and can capture still images and moving images. The wireless signal can be, for example, WiFi, BLUETOOTH, or other wireless communication scheme.
The smartphone 30 is installed with application software for operating the camera 20 wirelessly. The smartphone 30 incorporates an antenna (not shown) for remote-controlling the camera 20 by a wireless signal.
　以上のように構成された本発明の実施の形態１に係る無線通信用補助具１に使用状態について、図面に基づいて説明する。
　撮影者は、スマートフォン３０を操作装置として機能させるプログラムであるカメラ２０を無線操作するためのアプリケーションソフトを起動する。このアプリケーションソフトの起動は、図２に示すように、操作画面３１に表示されたショートカットアイコン３２をタップする。
　ショートカットアイコン３２をタップすることで起動したアプリケーションソフトによって、カメラ２０からの映像が操作画面３１にファインダー３３として表示される（図３参照）。撮影者は、このファインダー３３を見て、気に入ったシーンが映ると、操作画面３１のシャッターボタン３４をタップしてカメラ２０に撮影を指示する。 A use state of the wireless communication aid 1 according to Embodiment 1 of the present invention configured as described above will be described with reference to the drawings.
The photographer activates application software for wirelessly operating the camera 20, which is a program that causes the smartphone 30 to function as an operation device. To start the application software, a shortcut icon 32 displayed on the operation screen 31 is tapped as shown in FIG.
By the application software activated by tapping the shortcut icon 32, the video from the camera 20 is displayed on the operation screen 31 as a viewfinder 33 (see FIG. 3). The photographer looks at the finder 33 and, when a favorite scene is reflected, taps the shutter button 34 on the operation screen 31 to instruct the camera 20 to shoot.
　このようなスマートフォン３０とカメラ２０との間の通信は、無線通信用補助具１である電線２００を介して行われる。
　スマートフォン３０からの無線信号は、スマートフォン３０内部のアンテナから空中に送信され、電線２００の他端部２０２から、芯線２１１（図６参照）を通信路の一部として電線２００の一端部２０１まで伝搬し、空中を介してカメラ２０の内部のアンテナに到達する。カメラ２０からの無線信号は、その反対方向の伝搬によりスマートフォン３０に到達する。 Such communication between the smartphone 30 and the camera 20 is performed via the electric wire 200 that is the wireless communication auxiliary tool 1.
A wireless signal from the smartphone 30 is transmitted from the antenna inside the smartphone 30 into the air, and propagates from the other end 202 of the electric wire 200 to the one end 201 of the electric wire 200 using the core wire 211 (see FIG. 6) as a part of the communication path. Then, it reaches the antenna inside the camera 20 through the air. The radio signal from the camera 20 reaches the smartphone 30 by propagation in the opposite direction.
　このようにして、カメラ２０のアンテナと、スマートフォン３０のアンテナとの間に、非接触状態で電線２００の両端部（一端部２０１，他端部２０２）を配置して、電線２００を介在させてカメラ２０とスマートフォン３０とが通信することで、カメラ２０とスマートフォン３０との間の無線通信は、電線２００を伝送路として行うことができるので、他の無線信号に妨害されずに通信を行うことができる。従って、無線通信用補助具１は、良好な通信環境を確保することができる。 Thus, the both ends (one end 201 and the other end 202) of the electric wire 200 are arranged in a non-contact state between the antenna of the camera 20 and the antenna of the smartphone 30, and the electric wire 200 is interposed. Since the camera 20 and the smartphone 30 communicate with each other, the wireless communication between the camera 20 and the smartphone 30 can be performed using the electric wire 200 as a transmission path, so that communication is performed without being interrupted by other wireless signals. Can do. Therefore, the wireless communication auxiliary tool 1 can ensure a good communication environment.
　また、電線２００をカメラ２０やスマートフォン３０に近接するだけでよいので、既存のカメラ２０またはスマートフォン３０を改造しなくてもよい。 Further, since the electric wire 200 only needs to be close to the camera 20 or the smartphone 30, it is not necessary to modify the existing camera 20 or the smartphone 30.
　更に、図１に示すように、電線２００が同軸ケーブルによって形成されているため、網状線が通信路となる芯線を外来ノイズから保護するシールドとして機能する。そのため、同軸ケーブルが伝送する無線信号に他の無線信号が混信することを抑制することができる。この無線信号は、３０ＭＨｚから３００ＭＨｚまでの超短波（ＶＨＦ：Very High Frequency）、３００ＭＨｚから３ＧＨｚまでの極超短波（ＵＨＦ：Ultra High Frequency）、３ＧＨｚから３０ＧＨｚまでのマイクロ波（ＳＨＦ：Super High Frequency）、３０ＧＨｚから３００ＧＨｚまでのミリ波（ＥＨＦ：Extra High Frequency）を使用することができる。
　特に、ＷｉＦｉまたはＢＬＵＥＴＯＯＴＨが使用するＵＨＦ帯、ＳＨＦ帯では、同軸ケーブルでの伝送においては高周波領域での信号の減衰が抑えられる。そのため、同軸ケーブルの長さに応じて飛躍的に通信距離を延ばすことができる。従って、更に良好な通信環境を確保することができるので、電線２００は高品質な通信を確保することができる。 Furthermore, as shown in FIG. 1, since the electric wire 200 is formed of a coaxial cable, the mesh wire functions as a shield that protects the core wire serving as a communication path from external noise. Therefore, it is possible to suppress interference of other radio signals with radio signals transmitted by the coaxial cable. This radio signal includes a very high frequency (VHF) from 30 MHz to 300 MHz, an ultra high frequency (UHF) from 300 MHz to 3 GHz, and a microwave (SHF: Super High Frequency) from 30 GHz to 30 GHz, 30 GHz. Millimeter waves (EHF: Extra High Frequency) up to 300 GHz can be used.
In particular, in the UHF band and SHF band used by WiFi or BLUETOOTH, signal attenuation in a high frequency region is suppressed in transmission using a coaxial cable. For this reason, the communication distance can be dramatically increased according to the length of the coaxial cable. Therefore, a better communication environment can be ensured, and the electric wire 200 can ensure high-quality communication.
　また、電線２００の一端部２０１とカメラ２０との間、電線２００の他端部２０２とスマートフォン３０との間が、電波方式による無線通信によるものである。カメラ２０やスマートフォン３０は、一般的に情報の送受信には、ＷｉＦｉやＢＬＵＥＴＯＯＴＨに代表される無線通信を使用している。 Further, the wireless communication between the one end portion 201 of the electric wire 200 and the camera 20 and the other end portion 202 of the electric wire 200 and the smartphone 30 are based on radio communication. The camera 20 and the smartphone 30 generally use wireless communication represented by WiFi and BLUETOOTH for transmission and reception of information.
　従って、電波方式による無線通信は、磁場の変動により情報や電力を伝送する電磁誘導方式および磁界結合と電界結合とによる磁界共鳴方式と異なり、電線２００の両端部（一端部２０１，他端部２０２）に効率よく磁界や電界を発生させるためのコイルを形成する必要がない。また、多種多様な機器が無線通信を採用しているため、無線通信用補助具１は情報伝送の応用範囲が広い。 Therefore, the radio communication by the radio wave method is different from the electromagnetic induction method in which information and power are transmitted due to the change of the magnetic field and the magnetic field resonance method by the magnetic field coupling and the electric field coupling. It is not necessary to form a coil for efficiently generating a magnetic field or electric field. In addition, since various devices employ wireless communication, the wireless communication auxiliary tool 1 has a wide range of application of information transmission.
（実施の形態２）
　本発明の実施の形態２に係る無線通信用補助具の一例である水中撮影用器具を、図面に基づいて説明する。なお、図４から図７において、図１と同じ構成のものは同符号を付して説明を省略する。
　水中撮影用器具は、カメラを陸上から遠隔操作する際に使用されるものである。 (Embodiment 2)
An underwater photographing instrument that is an example of an auxiliary tool for wireless communication according to Embodiment 2 of the present invention will be described with reference to the drawings. 4 to 7, the same components as those in FIG. 1 are denoted by the same reference numerals and description thereof is omitted.
The underwater photographing instrument is used when the camera is remotely operated from land.
　従来では、水中でのカメラ撮影は、撮影者がカメラと共に水中に潜水しなければ、水上または陸上から遠隔操作により行う必要がある。水中に沈めたカメラを遠隔操作できるものとして、特許文献２に記載されたものが知られている。また、水中で撮影可能なものとして、特許文献３に記載されたものが知られている。 Conventionally, underwater camera photography must be performed remotely from the water or land, unless the photographer dives with the camera. The thing described in patent document 2 is known as what can remotely control the camera sunk in water. Moreover, what was described in patent document 3 is known as what can be image | photographed in water.
　特許文献２に記載の吊り下げ型無線テレビカメラは、下面を透明窓とした水密構造のコンテナ内に、下向きのテレビカメラとその電源及び該テレビカメラでの画像信号を無線発信する回路を内蔵し、無線発信するための送信アンテナとして偏平なフィーダー線を無線発信する回路に接続し、且つ該フィーダー線で該コンテナを長さ自在に吊り下げるというものである。 The suspension type wireless TV camera described in Patent Document 2 includes a downward-facing TV camera, its power supply, and a circuit for wirelessly transmitting image signals from the TV camera in a watertight container with a transparent window on the lower surface. A flat feeder line is connected to a circuit for wireless transmission as a transmission antenna for wireless transmission, and the container is suspended freely by the feeder line.
　特許文献３に記載のカメラシステム及び防水ハウジングは、防水ハウジングの操作スイッチの操作状態に応じてスイッチ検出部から操作状態信号が無線送信部に出力されと、無線送信部がアンテナを介して無線通信アダプタに操作状態信号を無線送信し、無線通信アダプタが、受信した操作状態信号を、コネクタを介してカメラ本体に転送し、カメラ本体内部の制御部が、コネクタを介して入力された操作状態信号に基づいて各種制御を実行するというものである。 In the camera system and the waterproof housing described in Patent Document 3, when the operation state signal is output from the switch detection unit to the wireless transmission unit according to the operation state of the operation switch of the waterproof housing, the wireless transmission unit performs wireless communication via the antenna. An operation state signal is wirelessly transmitted to the adapter, the wireless communication adapter transfers the received operation state signal to the camera body via the connector, and an operation state signal input by the control unit inside the camera body via the connector. Various controls are executed based on the above.
　しかし、特許文献２に記載の吊り下げ型無線テレビカメラでは、無線発信する回路に接続されたフィーダー線がアンテナに接続されているので、この技術を既存のカメラに適用するには、既存のカメラの筐体に貫通孔を設けて、電線を接続する必要があるため、適用が困難である。また、アンテナに直接フィーダー線を接続すると、フィーダー線の長さと、無線信号の波長との関係から、無線通信に支障が生じるおそれがある。
　また、特許文献３に記載のカメラシステム及び防水ハウジングでは、防水ハウジング内部で無線通信するもので、遠隔操作できるものではない。 However, in the suspension type wireless television camera described in Patent Document 2, since the feeder line connected to the circuit for wireless transmission is connected to the antenna, the existing camera is applied to this technology for the existing camera. Since it is necessary to provide a through hole in the housing and connect the electric wire, it is difficult to apply. Further, when the feeder line is directly connected to the antenna, there is a possibility that trouble may occur in wireless communication due to the relationship between the length of the feeder line and the wavelength of the wireless signal.
Further, the camera system and the waterproof housing described in Patent Document 3 perform wireless communication inside the waterproof housing and cannot be remotely operated.
　そこで、無線信号が伝搬しにくい水中に所在する無線操作可能なカメラを、大きく変更することなく、水上または陸上から無線操作することが可能な水中撮影用器具が望まれている。 Therefore, there is a demand for an underwater photographing instrument that can be wirelessly operated from the water or land without greatly changing a wirelessly operable camera located in water where radio signals are difficult to propagate.
　図４および図５に示すように水中撮影用器具１００は、水中撮影用のハウジング１０に収納されるカメラ２０を、陸上、または水上などから、操作装置であるスマートフォン３０にて、遠隔操作するときに、使用されるものである。 As shown in FIGS. 4 and 5, the underwater photographing instrument 100 is used when the camera 20 housed in the underwater photographing housing 10 is remotely operated on the smartphone 30 as an operation device from land or water. Is used.
　水中撮影用器具１００は、ハウジング１０とカメラ２０との間に配線される電線２００と、電線２００の一端部２０１をハウジング１０に接続する接続用部材３００と、棒状支持用部材であるロッド４００と備えている。
　電線２００は、同軸ケーブルである。図６に示すように、電線２００は、導線部２１０と、被覆部２２０とを備えている。導線部２１０は、芯線２１１と、芯線２１１と対をなす網状線２１２とから構成される。被覆部２２０は、芯線２１１を覆う内部絶縁体２２１と、網状線２１２を覆う外皮絶縁体２２２とから構成されている。 The underwater photographing instrument 100 includes an electric wire 200 that is wired between the housing 10 and the camera 20, a connection member 300 that connects one end 201 of the electric wire 200 to the housing 10, and a rod 400 that is a rod-like support member. I have.
The electric wire 200 is a coaxial cable. As shown in FIG. 6, the electric wire 200 includes a conducting wire part 210 and a covering part 220. The conducting wire part 210 includes a core wire 211 and a mesh wire 212 that forms a pair with the core wire 211. The covering portion 220 includes an internal insulator 221 that covers the core wire 211 and a skin insulator 222 that covers the mesh wire 212.
　図５および図６に示すように、接続用部材３００は、電線２００の一端部２０１を、水密状態で、かつカメラ２０と非接触状態でハウジング１０に配置するものである。接続用部材３００は、樹脂製である。接続用部材３００は、第１部分３１０と、第２部分３２０と、固定用部材３３０とを備えている。 As shown in FIGS. 5 and 6, the connecting member 300 is one in which one end 201 of the electric wire 200 is disposed in the housing 10 in a watertight state and in a non-contact state with the camera 20. The connection member 300 is made of resin. The connection member 300 includes a first part 310, a second part 320, and a fixing member 330.
　第１部分３１０は、ハウジング１０の側面に密着した状態で接続される。第１部分３１０は、細長の直方体状に形成されている。第１部分３１０には、被覆部２２０から露出した芯線２１１が内部に収納される細長の第１空間３１１が形成されている。ハウジング１０への接続は、ハウジング１０と、第１部分３１０および第２部分３２０とを一体成形してもよい。ハウジング１０と、第１部分３１０および第２部分３２０とを一体成形した場合には、水中撮影用器具１００は、水中撮影用器具１００付きのハウジング１０として販売することができる。 The first portion 310 is connected in close contact with the side surface of the housing 10. The first portion 310 is formed in an elongated rectangular parallelepiped shape. The first portion 310 is formed with an elongated first space 311 in which the core wire 211 exposed from the covering portion 220 is accommodated. For connection to the housing 10, the housing 10 and the first portion 310 and the second portion 320 may be integrally formed. When the housing 10 is integrally formed with the first portion 310 and the second portion 320, the underwater photographing instrument 100 can be sold as the housing 10 with the underwater photographing instrument 100.
　また、ハウジング１０が市販されているような既存のものであるときには、第１部分３１０を、ハウジング１０に溶着させたり、接着材や両面テープなどで貼り付けたり、ねじ止めしたりすることができる。
　また、ハウジング１０にスロットを設け、接続用部材の第１部分に板状突起を形成して、板状突起をスライドさせて、スロットに嵌め込み、接続用部材をハウジングに固定するようにしてもよい。 In addition, when the housing 10 is an existing one that is commercially available, the first portion 310 can be welded to the housing 10, attached with an adhesive or a double-sided tape, or screwed. .
Alternatively, the housing 10 may be provided with a slot, a plate-like protrusion is formed on the first portion of the connecting member, the plate-like protrusion is slid and fitted into the slot, and the connecting member is fixed to the housing. .
　第２部分３２０には、芯線２１１以外の軸太部分である内部絶縁体２２１，網状線２１２および外皮絶縁体２２２が収納される第２空間３２１が形成されている。また、固定用部材３３０のための雄ねじ面３２２が形成されている。
　固定用部材３３０は、電線２００を水密に第２部分３２０に固定するためのものである。固定用部材３３０は、電線２００が挿通され、雄ねじ面３２２にねじ込まれる第１ナット３３１および第２ナット３３２と、電線２００に巻き付けられた、または挿通させたパッキン部３３３を備えている。パッキン部３３３は、第２ナット３３２の内周面と電線２００の外周面との隙間を塞ぎ、水密性を確保するものである。 The second portion 320 is formed with a second space 321 in which the inner insulator 221, the mesh wire 212 and the outer skin insulator 222 which are thick shaft portions other than the core wire 211 are accommodated. In addition, a male screw surface 322 for the fixing member 330 is formed.
The fixing member 330 is for fixing the electric wire 200 to the second portion 320 in a watertight manner. The fixing member 330 includes a first nut 331 and a second nut 332 through which the electric wire 200 is inserted and screwed into the male screw surface 322, and a packing portion 333 wound around or inserted through the electric wire 200. The packing part 333 closes the gap between the inner peripheral surface of the second nut 332 and the outer peripheral surface of the electric wire 200 to ensure water tightness.
　図４および図７に示すように、電線２００の一端部２０１の反対側である他端部２０２は、スマートフォン３０と非接触状態で配置される。電線２００の他端部２０２は、芯線２１１を被覆した内部絶縁体２２１を、外皮絶縁体２２２と網状線２１２とから露出した状態に形成されている。従って、芯線２１１は内部絶縁体２２１により被覆されたままであり、網状線２１２は外皮絶縁体２２２被覆されたままとすることができる。
　電線２００の他端部２０２は、スマートフォン３０側に配置されていればよいため、外皮絶縁体２２２が全体を被覆した同軸ケーブルを切断したままの状態であったり、内部絶縁体２２１から芯線２１１が露出した状態であったりしてもよい。しかし、芯線２１１を保護するためには、芯線２１１は内部絶縁体２２１に覆われた状態とすることが望ましい。
　図４に示すように、ロッド４００は、段階的に伸縮するロッド本体４１０と、ハウジング１０を取り付けたり、カメラ２０を直接取り付けたりすることができる取付台４２０とを備えている。 As shown in FIGS. 4 and 7, the other end 202 that is the opposite side of the one end 201 of the electric wire 200 is arranged in a non-contact state with the smartphone 30. The other end 202 of the electric wire 200 is formed in a state in which the internal insulator 221 covering the core wire 211 is exposed from the skin insulator 222 and the mesh wire 212. Accordingly, the core wire 211 can remain covered with the inner insulator 221 and the mesh wire 212 can remain covered with the outer insulator 222.
Since the other end portion 202 of the electric wire 200 only needs to be disposed on the smartphone 30 side, the coaxial cable covering the whole with the outer insulator 222 is cut, or the core 211 is connected from the inner insulator 221. It may be exposed. However, in order to protect the core wire 211, it is desirable that the core wire 211 is covered with the internal insulator 221.
As shown in FIG. 4, the rod 400 includes a rod main body 410 that expands and contracts in stages, and a mounting base 420 to which the housing 10 can be attached or the camera 20 can be directly attached.
　次に、ハウジング１０について説明する。
　図５に示すように、ハウジング１０は、カメラ２０を水中でも安全に使用できるように水密性を有している。ハウジング１０は、内部のカメラ２０の状態が外部から視認しやすいように透明樹脂により形成されている。ハウジング１０は、カメラ２０を内部に収納するために、カメラ２０の外形に適合した収納空間が形成されている。 Next, the housing 10 will be described.
As shown in FIG. 5, the housing 10 has water tightness so that the camera 20 can be used safely in water. The housing 10 is formed of a transparent resin so that the state of the internal camera 20 is easily visible from the outside. The housing 10 is formed with a storage space suitable for the outer shape of the camera 20 in order to store the camera 20 therein.
　以上のように構成された本発明の実施の形態２に係る水中撮影用器具１００における使用状態について、図面に基づいて説明する。
　図４に示すように、撮影者は、カメラ２０が収納されたハウジング１０をロッド４００の取付台４２０に取り付け、ロッド本体４１０を適当な長さに調整した後、ロッド４００の基端部を持って、先端部のカメラ２０を水中に浸漬する。
　次に、撮影者は、実施の形態１にて、図２および図３を用いて説明したようにして、スマートフォン３０によりカメラ２０を操作して撮影する。 A use state of the underwater photographing instrument 100 according to Embodiment 2 of the present invention configured as described above will be described with reference to the drawings.
As shown in FIG. 4, the photographer attaches the housing 10 housing the camera 20 to the mounting base 420 of the rod 400, adjusts the rod body 410 to an appropriate length, and then holds the base end of the rod 400. Then, the camera 20 at the tip is immersed in water.
Next, the photographer operates the camera 20 with the smartphone 30 to shoot as described with reference to FIGS. 2 and 3 in the first embodiment.
　スマートフォン３０からカメラ２０までの間の通信路に水が介在することなく、電線２００を通信路として無線信号が伝搬するため、スマートフォン３０とカメラ２０との間での無線信号は、大幅な減衰を伴うことなく、通信することができる。
　また、接続用部材３００は、ハウジング１０の外側面に接触するように配置されている。そのため、既存のハウジング１０であっても、ハウジング１０の外側面に接続用部材３００を接着したり、溶着したりするなどして、接続用部材３００をハウジング１０に接続すればよいので、容易に、接続用部材３００をハウジング１０に設けることができる。
　また、接続用部材３００は、電線２００の被覆部２２０から露出した芯線２１１を収納して水密状態にしているため、ハウジング１０と電線２００との間に水を介在させることなく、電線２００をハウジング１０の近接した位置に配置することができる。 Since water does not intervene in the communication path from the smartphone 30 to the camera 20 and the radio signal propagates through the electric wire 200 as a communication path, the radio signal between the smartphone 30 and the camera 20 is significantly attenuated. You can communicate without it.
Further, the connection member 300 is arranged so as to contact the outer surface of the housing 10. Therefore, even if it is the existing housing 10, since the connection member 300 should just be connected to the housing 10 by adhere | attaching or welding the connection member 300 to the outer surface of the housing 10, it is easy. The connecting member 300 can be provided in the housing 10.
Further, since the connecting member 300 accommodates the core wire 211 exposed from the covering portion 220 of the electric wire 200 and is in a watertight state, the electric wire 200 can be accommodated without interposing water between the housing 10 and the electric wire 200. It can be arranged at 10 adjacent positions.
　従って、水中撮影用器具１００をカメラ２０とスマートフォン３０との間に介在させることで、水中での撮影には不向きな無線操作可能なカメラ２０を大きく変更することなく、ハウジング１０に収納して水中で撮影することができる。 Therefore, by interposing the underwater photographing instrument 100 between the camera 20 and the smartphone 30, the camera 20 that can be operated wirelessly, which is unsuitable for underwater photographing, is housed in the housing 10 without being greatly changed. You can shoot with
　更に、図６に示すように、電線２００が同軸ケーブルによって形成されているため、網状線２１２が通信路となる芯線２１１を外来ノイズから保護するシールドとして機能する。従って、電線２００は高品質な通信を確保することができる。 Furthermore, as shown in FIG. 6, since the electric wire 200 is formed of a coaxial cable, the mesh wire 212 functions as a shield that protects the core wire 211 serving as a communication path from external noise. Therefore, the electric wire 200 can ensure high-quality communication.
　本実施の形態２では、図４に示すように、ハウジング１０はロッド４００の先端に取り付けられていたが、接続用部材３００とハウジング１０との接続強度、電線２００の強度が十分であれば、ロッド４００を使わずに、電線２００によりカメラ２０を収納したハウジング１０を直接吊り下げてもよい。
　また、ロッド４００は伸縮するものであるが、ハウジング１０が先端部に取り付けられる取付台４２０を備えていれば、棒状支持用部材は、複数のパーツに分離するものであったり、伸縮できないものであったりしてもよい。 In Embodiment 2, as shown in FIG. 4, the housing 10 is attached to the tip of the rod 400. However, if the connection strength between the connection member 300 and the housing 10 and the strength of the electric wire 200 are sufficient, Instead of using the rod 400, the housing 10 housing the camera 20 may be directly suspended by the electric wire 200.
In addition, the rod 400 expands and contracts, but if the housing 10 includes a mounting base 420 that is attached to the tip, the rod-like support member is separated into a plurality of parts or cannot be expanded or contracted. There may be.
　（実施の形態３）
　本発明の実施の形態３に係る水中撮影用器具について、図面に基づいて説明する。
　図８に示す本実施の形態３に係る水中撮影用器具は、電線２００の一端部２０１がハウジング１０を貫通して、ハウジング１０内の空間に電線２００を突出させている。図示しない電線２００の他端部２０２は、図１および図４と同様にスマートフォン３０と非接触状態であればよい。 (Embodiment 3)
An underwater photographing instrument according to Embodiment 3 of the present invention will be described with reference to the drawings.
In the underwater photographing instrument according to the third embodiment shown in FIG. 8, one end 201 of the electric wire 200 penetrates the housing 10, and the electric wire 200 protrudes into the space in the housing 10. The other end 202 of the electric wire 200 (not shown) may be in a non-contact state with the smartphone 30 as in FIGS. 1 and 4.
　電線２００は、一端部２０１の外皮絶縁体２２２と網状線２１２とが除去されていると共に、内部絶縁体２２１から芯線２１１が露出している。
　ハウジング１０には、チューブ３４０が貫通している。このチューブ３４０に電線２００の一端部２０１が挿通している。そして、第１ナット３３１および第２ナット３３２により電線２００の一端部２０１をチューブ３４０の上から締め付けることで、電線２００の一端部２０１がハウジング１０に固定されている。
　このように、電線２００の一端部２０１がハウジング１０を貫通して、ハウジング１０内の空間に電線２００を突出させているため、電線２００の一端部２０１からの無線信号を、水密状態のハウジング１０内の空間に放出させることができる。 In the electric wire 200, the outer shell insulator 222 and the mesh wire 212 at the one end 201 are removed, and the core wire 211 is exposed from the inner insulator 221.
A tube 340 passes through the housing 10. One end 201 of the electric wire 200 is inserted through the tube 340. The one end 201 of the electric wire 200 is fastened to the housing 10 by tightening the one end 201 of the electric wire 200 from above the tube 340 with the first nut 331 and the second nut 332.
Thus, since the one end portion 201 of the electric wire 200 penetrates the housing 10 and the electric wire 200 protrudes into the space in the housing 10, the wireless signal from the one end portion 201 of the electric wire 200 is transmitted to the watertight housing 10. Can be released into the interior space.
　（実施の形態４）
　本発明の実施の形態４に係る水中撮影用器具について、図面に基づいて説明する。
　図９に示す本実施の形態４に係る水中撮影用器具は、電線２００の一端部２０１がハウジング１０に埋入されている。図示しない電線２００の他端部２０２は、図１および図４と同様にカメラ２０と非接触状態であればよい。 (Embodiment 4)
An underwater photographing instrument according to Embodiment 4 of the present invention will be described with reference to the drawings.
In the underwater photographing instrument according to the fourth embodiment shown in FIG. 9, one end 201 of the electric wire 200 is embedded in the housing 10. The other end 202 of the electric wire 200 (not shown) may be in a non-contact state with the camera 20 as in FIGS.
　電線２００は、一端部２０１の外皮絶縁体２２２と網状線２１２とが除去されていると共に、内部絶縁体２２１から芯線２１１が露出している。
　ハウジング１０への電線２００の一端部２０１の埋入は、ハウジング１０を成形する際に、ハウジング１０の成形金型内の成形用空間（キャビティ）に電線２００の一端部２０１を配置する。そうすることで、ハウジング１０が成形されると、電線２００の一端部２０１がハウジング１０と一体的に隙間無くハウジング１０に埋入した状態となる。
　このように、電線２００の一端部２０１がハウジング１０に埋入されていることで、一端部を水密状態で、かつカメラ２０と非接触状態とすることができるので、電線２００の一端部２０１からの無線信号を、ハウジング１０を透過させてハウジング１０内の空間に放出させることができる。 In the electric wire 200, the outer shell insulator 222 and the mesh wire 212 at the one end 201 are removed, and the core wire 211 is exposed from the inner insulator 221.
In embedding the one end portion 201 of the electric wire 200 in the housing 10, when the housing 10 is formed, the one end portion 201 of the electric wire 200 is disposed in a molding space (cavity) in the molding die of the housing 10. By doing so, when the housing 10 is molded, the one end 201 of the electric wire 200 is embedded in the housing 10 integrally with the housing 10 without a gap.
Thus, since the one end 201 of the electric wire 200 is embedded in the housing 10, the one end can be brought into a watertight state and in a non-contact state with the camera 20. The radio signal can be transmitted through the housing 10 and released into the space inside the housing 10.
（実施の形態５）
　本発明の実施の形態５に係る水中撮影用器具について図面に基づいて説明する。
　本実施の形態５では、スマートフォン３０（図１参照）側に配置される電線２００の他端部２０２に、図１０に示すように、スマートフォン３０のイヤホンジャック（第１コネクタ）に嵌合するイヤホンプラグ５００（第２コネクタ）が設けられている。 (Embodiment 5)
An underwater photographing instrument according to Embodiment 5 of the present invention will be described with reference to the drawings.
In the fifth embodiment, as shown in FIG. 10, the earphone fitted to the earphone jack (first connector) of the smartphone 30 at the other end 202 of the electric wire 200 arranged on the smartphone 30 (see FIG. 1) side. A plug 500 (second connector) is provided.
　イヤホンプラグ５００は、電線２００の通信路となる導線部２１０（芯線２１１）と導通状態としている。従って、イヤホンプラグ５００をスマートフォン３０のイヤホンジャックに嵌合させると、導線部２１０はスマートフォン３０の音声出力回路に接続される。そして、スマートフォン３０によりカメラ２０を操作しているときは、スマートフォン３０は、音声出力しておらず、電線２００による無線信号の伝搬も微小電力である。そのため、イヤホンプラグ５００に導線部２１０が導通状態であっても、音声出力回路に悪影響を及ぼさない。 The earphone plug 500 is in a conductive state with the conducting wire portion 210 (core wire 211) that becomes the communication path of the electric wire 200. Therefore, when the earphone plug 500 is fitted into the earphone jack of the smartphone 30, the conducting wire part 210 is connected to the audio output circuit of the smartphone 30. And when operating the camera 20 with the smart phone 30, the smart phone 30 is not carrying out audio | voice output, and propagation of the radio signal by the electric wire 200 is also micro electric power.
