近年、一般市販のデジタルカメラやビデオカメラは高解像度で高倍率ズームを搭載した機種が多数あり、これらに遠隔撮影装置を装着できればコストパフォーマンスに優れた小型軽量な遠隔撮影装置を得ることができるが、最近はシャッターボタンとズームレバーが一体になったタイプが多くなり、特許文献２に記載のようなボタンを押圧させる方式のズームを搭載した機種は少なくなった。  In recent years, many commercially available digital cameras and video cameras have high resolution and high magnification zoom, and if you can attach a remote shooting device to these, you can obtain a small and lightweight remote shooting device with excellent cost performance. Recently, the type in which the shutter button and the zoom lever are integrated has increased, and the number of models equipped with the zoom of the method of pressing the button as described in Patent Document 2 has decreased.

そこで本発明では、シャッターボタンとズームレバーが一体になったタイプに装着可能な遠隔撮影装置を提供することを目的とするものである。  Accordingly, an object of the present invention is to provide a remote photographing apparatus that can be mounted on a type in which a shutter button and a zoom lever are integrated.

本発明に係わる遠隔撮影装置は、カメラのズーム操作レバー付シャッターボタンに取り付けた押圧回転伝達部材と、前記押圧回転伝達部材に接続して押圧させる電磁ソレノイドと、前記電磁ソレノイドの作動軸を回転させるロータリーアクチュエーターとから構成したことを特徴とする遠隔撮影装置であって、これによりシャッターボタンとズームレバーが一体になったタイプのカメラに装着可能な遠隔撮影装置を提供できるものである。  A remote imaging device according to the present invention includes a pressing rotation transmission member attached to a shutter button with a zoom operation lever of a camera, an electromagnetic solenoid connected to the pressing rotation transmission member and pressed, and an operation shaft of the electromagnetic solenoid is rotated. A remote photographing apparatus comprising a rotary actuator, which can provide a remote photographing apparatus that can be attached to a camera of a type in which a shutter button and a zoom lever are integrated.

本発明の遠隔撮影装置によれば、一般市販のデジタルカメラやビデオカメラの多くの機種に装着できるため、専用にカメラを開発する必要がなく、コストパフォーマンスに優れた小型軽量で高画質・高倍率ズーム機能を備えた遠隔撮影装置を得ることができる。  According to the remote photographing apparatus of the present invention, since it can be attached to many models of general commercially available digital cameras and video cameras, it is not necessary to develop a dedicated camera, and it is compact and lightweight with excellent cost performance, high image quality and high magnification. A remote imaging device having a zoom function can be obtained.

デジタルカメラの一例を示している。An example of a digital camera is shown. 本発明の遠隔撮影装置の一例を示している。1 shows an example of a remote photographing apparatus of the present invention. 可搬式操作盤の一例を示している。An example of a portable operation panel is shown.

以下に本発明の好ましい一実施形態を添付図面に基づき説明する。図１は一般市販の代表的なコンパクトタイプのデジタルカメラの一例である。近年急速に性能の向上と小型軽量化ならびにコストダウン化が進み、現時点では静止画の画素数が１６００万画素、光学ズームは１０倍以上、重量が１５０〜２００ｇ程度の機種が一般的になっており、数年前と比較するとコストパフォーマンスは極めて高いレベルにある。  Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an example of a typical compact digital camera on the market. In recent years, the performance has been improved rapidly, the size and weight have been reduced, and the cost has been reduced. At present, models with 16 million pixels of still images, optical zooms of 10 times or more, and weights of about 150 to 200 g have become common. The cost performance is at a very high level compared to several years ago.

図１はデジタルカメラの３面図であって、（ａ）図は上面、（ｂ）図は背面、（ｃ）図は側面を示す。コンパクトタイプのデジタルカメラ１のシャッターボタンは１ａ、ズーム操作レバーは１ｂ、１ｃはレンズ、１ｄは液晶モニター、１ｅは映像出力端子、１ｆはメニューやモードなどの設定を行うためのボタンである。 尚、シャッターボタンとズーム操作レバーは一体になっており、ズーム操作レバーを操作するとシャッターボタンと共に左右に一定角度回転させることができ、それによってズームアップとズームダウンを行う。  1A and 1B are three views of a digital camera, where FIG. 1A shows a top view, FIG. 1B shows a rear view, and FIG. 1C shows a side view. The shutter button of the compact digital camera 1 is 1a, the zoom operation lever is 1b, 1c is a lens, 1d is a liquid crystal monitor, 1e is a video output terminal, and 1f is a button for setting menus and modes. The shutter button and the zoom operation lever are integrated, and when the zoom operation lever is operated, the shutter button and the zoom operation lever can be rotated to the left and right by a certain angle, thereby performing zoom up and zoom down.

図２は本発明のカメラのズーム操作レバー付シャッターボタンに取り付けた押圧回転伝達部材と、前記押圧回転伝達部材に接続して押圧させる電磁ソレノイドと、前記電磁ソレノイドの作動軸を回転させるロータリーアクチュエーターとから構成した遠隔撮影装置を示しており、（ａ）図は上面を、（ｂ）図は背面を、（ｃ）図は側面を示す。２はシャッターボタンを押圧させる電磁ソレノイドであって、コイルが内蔵されたケース２ａとプランジャー２ｂと作動軸２ｃなどから構成されており、コイルに電流が流れると電磁力によって作動軸２ｃが押し出される。（図では下方向に押し出される）作動軸２ｃの一方（図では下側）の先端部は押圧回転伝達部材３に接続されており、他方（図では上側）の先端部には歯車４ａが取り付けられている。尚、電磁ソレノイドは、例えば市販のプッシュプル式ソレノイドのＤＣ３〜１２Ｖ程度のタイプが小型軽量で使い易い。  FIG. 2 shows a pressing rotation transmission member attached to a shutter button with a zoom operation lever of a camera according to the present invention, an electromagnetic solenoid connected to the pressing rotation transmission member and pressed, and a rotary actuator for rotating an operating shaft of the electromagnetic solenoid. (A) The figure shows the upper surface, (b) The figure shows the back, and (c) The figure shows the side. Reference numeral 2 denotes an electromagnetic solenoid that presses the shutter button. The electromagnetic solenoid 2 includes a case 2a with a built-in coil, a plunger 2b, an operating shaft 2c, and the like. When an electric current flows through the coil, the operating shaft 2c is pushed out by electromagnetic force. . One end (lower side in the figure) of the operating shaft 2c (pushed downward in the figure) is connected to the press rotation transmission member 3, and a gear 4a is attached to the other end (upper side in the figure). It has been. As the electromagnetic solenoid, for example, a commercially available push-pull solenoid of about 3 to 12 VDC is small and light and easy to use.

５はロータリーアクチュエーターであって、回転シャフト５ａには歯車４ｂが取り付けられており、前記の歯車４ａと噛み合って作動軸２ｃに回転を伝達する。尚、ロータリーアクチュエーター５は市販の各種のモーターやロータリーソレノイドなどで、例えば３〜１２Ｖ程度の小型ＤＣモーターを使用することができる。  Reference numeral 5 denotes a rotary actuator, and a gear 4b is attached to the rotary shaft 5a, and meshes with the gear 4a to transmit the rotation to the operating shaft 2c. The rotary actuator 5 is a variety of commercially available motors, rotary solenoids, etc., and a small DC motor of about 3 to 12 V, for example, can be used.

前記の押圧回転伝達部材３は、シャッターボタン１ａに接着材又は粘着材３ａや小ネジ（図示せず）などによって取り付けられており、前記電磁ソレノイド２を作動させると、作動軸２ｃが下方向に押し出されて押圧回転伝達部材３を通じてシャッターボタン１ａを押すことによってシャッターを切ることができる。又、ロータリーアクチュエーター５を作動させると、電磁ソレノイド２の作動軸２ｃと押圧回転伝達部材３を通じてズーム操作レバーを回転させることでズームアップとズームダウンを行うことができる。尚、押圧回転伝達部材３は金属や樹脂でも良いが、ゴムやウレタンなどの弾性材料を使用すればシャッターボタンを押圧する際の衝撃を柔らげることができる。又、押圧回転伝達部材３と作動軸２ｃとの接続は、押圧回転伝達部材３に設けた軸穴に作動軸２ｃを嵌め込んでから止めネジで固定するなどの方法（図示せず）を行えば簡単である。  The pressing rotation transmitting member 3 is attached to the shutter button 1a by an adhesive or adhesive material 3a, a small screw (not shown) or the like, and when the electromagnetic solenoid 2 is operated, the operating shaft 2c is moved downward. The shutter can be released by pushing the shutter button 1a through the pressing rotation transmitting member 3 after being pushed out. Further, when the rotary actuator 5 is operated, zooming up and zooming down can be performed by rotating the zoom operation lever through the operating shaft 2c of the electromagnetic solenoid 2 and the pressing rotation transmitting member 3. The pressing rotation transmitting member 3 may be a metal or a resin, but if an elastic material such as rubber or urethane is used, the impact when pressing the shutter button can be softened. The connection between the pressing rotation transmission member 3 and the operating shaft 2c is performed by a method (not shown) such as fitting the operating shaft 2c into a shaft hole provided in the pressing rotation transmission member 3 and then fixing with the set screw. It ’s easy.

前記電磁ソレノイド２の作動軸２ｃを作動させると軸方向に一定ストローク、例えば２ｍｍ程度移動してシャッターボタンを押圧するので、歯車４ａと４ｂの噛み合いがはずれないように、歯車の厚さを前記ストローク分が移動してもはずれない様な厚さにしている。本例は電磁ソレノイド２とロータリーアクチュエーター５を平行に配置して歯車で回転を伝達する構造を示しているが、これらを直線的に配置しても良い。尚、その場合にも作動軸２ｃの軸方向の移動が可能なように、例えばロータリーアクチュエーターと伸縮ジョイントなどを介して作動軸２ｃと接続する構造や、ロータリーアクチュエーターがスライドできる構造にすれば良い。  When the operating shaft 2c of the electromagnetic solenoid 2 is actuated, it moves in a certain stroke in the axial direction, for example, about 2 mm, and presses the shutter button. The thickness is such that the minute does not move even if it moves. In this example, the electromagnetic solenoid 2 and the rotary actuator 5 are arranged in parallel and the rotation is transmitted by a gear, but these may be arranged linearly. In this case as well, a structure in which the operating shaft 2c is connected to the operating shaft 2c via, for example, a rotary actuator and an expansion / contraction joint, or a structure in which the rotary actuator can slide can be used so that the operating shaft 2c can move in the axial direction.

６は前記電磁ソレノイド２とロータリーアクチュエーター５を取り付けるためのベース部材であって、例えば１〜２ｍｍ程度の厚さのアルミ板である。７はカメラ１に取り付ける支持部材であって、例えば図に示す様に接着材７ａを使ってカメラ１に接着されているが、クランプ方式でカメラに固定しても良い。部材６は例えば小ネジ６ａを使って支持部材７に固定されている。尚、電磁ソレノイドやロータリーアクチュエーターに接続されているケーブルは便宜上図示しない。  Reference numeral 6 denotes a base member for attaching the electromagnetic solenoid 2 and the rotary actuator 5 and is an aluminum plate having a thickness of about 1 to 2 mm, for example. A support member 7 is attached to the camera 1 and is bonded to the camera 1 using an adhesive 7a as shown in the figure, but may be fixed to the camera by a clamp method. The member 6 is fixed to the support member 7 using, for example, a small screw 6a. Note that the cables connected to the electromagnetic solenoid and the rotary actuator are not shown for convenience.

図３は本発明の遠隔撮影装置を操作するための可搬式操作盤１０の一例であり、１０ａは画像表示用のモニター、１０ｂはシャッター作動用の押しボタン、１０ｃと１０ｄは各々ズームをアップ・ダウンさせるための操作用押しボタンである。１０ｅは前記電磁ソレノイド２とロータリーアクチュエーター５を作動させるためのケーブルに接続するコネクター、１０ｆは映像入力端子であってカメラに備えた映像出力端子１ｅに接続される。それによって、遠隔でカメラのライブ映像をモニター１０ａで見ながら、シャッターとズームを操作することができる。  FIG. 3 shows an example of the portable operation panel 10 for operating the remote photographing apparatus of the present invention. 10a is a monitor for displaying an image, 10b is a push button for operating a shutter, and 10c and 10d are each a zoom-in device. This is a push button for operation to bring it down. A connector 10e is connected to a cable for operating the electromagnetic solenoid 2 and the rotary actuator 5, and 10f is a video input terminal which is connected to a video output terminal 1e provided in the camera. Thereby, the shutter and zoom can be operated while viewing the live image of the camera remotely on the monitor 10a.

以上の発明によって、一般市販の多数の機種のデジタルカメラやビデオカメラに遠隔撮影装置を容易に装着することが可能になった。  With the above invention, it has become possible to easily attach a remote photographing device to a large number of digital cameras and video cameras on the market.
