Description

【０００１】
【発明の属する技術分野】
本発明は、スポットライト等の照明機器、監視カメラ等の電子機器を、天井や壁面等に取付けるための角度調整装置に関するものである。
【０００２】
【従来の技術】
この種の角度調整装置には、カメラを取付けるものとして、例えば、図５で示すように、壁面、天井への固定部７ａと十字状にブラケット保持孔を有する固定部７ｂをもつ取付台アーム７と、この保持孔内で回転自在であって、かつ固定されるブラケット８と、カメラ取付アングル９と、カメラ固定ツマミ１０と、カメラ取付角度調整ツマミ１１と、ブラケット固定板１２と、蝶ねじ１３から構成されているものがある。
図示しないカメラをカメラ固定ツマミ１０で固定したカメラ取付アングル９に、ブラケット８がカメラ取付角度調整ツマミ１１で取付けられ、そのブラケット８を固定部７ｂのブラケット保持孔に挿通し、ブラケット８が、ブラケット固定板１２を蝶ねじ１３によって固定部７ｂのねじ穴に螺着することにより、固定部７ｂのブラケット保持孔に保持される取付台アーム７を、壁面や天井に取付けるものとなっている。
このような構成では、カメラ取付角度調整ツマミ１１により、カメラをある角度に設定後、その状態で取付台アーム７を支点として、カメラ取付アングル９と取付台アーム７との間のブラケット８が回転し、カメラを水平方向に回転できる。（特許文献１参照）
【０００３】
また、図６で示すように、小型のカメラを部屋の天井に固着する装置として、天井裏に配設する天井吊り金具１４と、天井を挟持して天井吊り金具１４に係止するベース金具１５と、同ベース金具１５の端部に立設してカメラ１９を片持ち支持するカメラ支持部１５ａと、カメラ１９に固着したカメラ固定金具１６と、カメラ支持部１５ａにカメラ固定金具１６を係着する係着部１５ｂ、１５ｃから構成されているものがある。
ベース金具１５を天井吊り金具１４に係止するときは、天井吊り金具１４に立てた２つのビス１４ａ、１４ｂの一方を透孔１５ｄから遊貫し、ビス１４ａ、１４ｂをＵ字溝１５ｅに貫入して、天井を挟持してビス１４ａ、１４ｂを天井吊り金具１４にネジ止めする。天井吊り金具１４とベース金具１５で挟持する天井（図示せず）の部分には、２つのビス１４ａ、１４ｂを遊貫する直径を備えた円孔が開口されおり、カメラ１９を天井に取り付けるときは、２つのビス１４ａ、１４ｂを弛めてカメラ１９の方位を所定の方向としてネジ１４ａ、１４ｂを締めることで、カメラ１９を任意の方位に設定することができる。
カメラ固定金具１６の側部に２つのネジ孔１６ａ、１６ｂが設けられ、ネジ孔１６ａ、１６ｂに対応する個所のカメラ支持部１５ａに、１つの透孔１５ｂとその透孔１５ｂを中心とする円周上の略１／４を開口した１つの長孔１５ｃが設けられている。
カメラ固定金具１６に固定ネジ１８で固着したカメラ１９をカメラ支持部１５ａに係着させるときは、２つのビス１７、１７をそれぞれ透孔１５ｂと長孔１５ｃに貫入してカメラ固定金具１６のネジ孔１６ａ、１６ｂに仮止めしてカメラ支持部１５ａの面方向に沿ってカメラ１９の仰角を変化させて任意の位置に設定して、２つのビス１７、１７を締めて係着する。
このような構成と作用によって、方位と仰角を変化させてカメラ１９の取付角度が設定される。（特許文献２参照）
【０００４】
以上のような角度調整が可能な装置においては、組立部品が多く必要な構造となっていた。
ところで、このように、大きく角度調整を必要としないが、カメラを取付けた後に、天井面の取付場所のばらつきやカメラの光軸のばらつき等によって、取付け方向に若干のずれを生じている場合に、これを調整する必要があった。
そこで、このずれを調整する装置が提案されている。
図７で示すように、矩形状の金属板の左右両側を折曲してフランジを設け、このフランジ内に天井や壁面等に取付けるための取付部を備える取付板２０と、矩形状の金属板の両側をコ字状になるように折曲され、折曲により形成された両側面以外の側面を取付板２０に固定し、他の両側面には回転軸２１ａと角度調整孔２１ｂを備える第一ブラケット２１と、第一ブラケット２１の内側に配置される十字状の金属端板からなり、対向する金属端板同士をコ字状になるように折曲し、一方の対向する金属端板は、第一ブラケット２１の回転軸２１ａに対応する軸受と角度調整孔２１ｂに対応する丸孔とを備え、回転軸２１ａを介して結合され、他方の対向する金属端板は、第一ブラケット２１の回転軸２１ａに直交する回転軸２２ａと角度調整孔２２ｂを備える第二ブラケット２２と、第二ブラケット２２の回転軸２２ａに対応する軸受と角度調整孔２２ｂに対応する丸孔とを備えてなり、回転軸２２ａを介して結合される監視カメラ２３と、第一ブラケット２１と第二ブラケット２２の各角度調整孔２１ｂ、２２ｂに挿通され、角度調整を行なうための各固定用ネジ２１ｃ、２２ｃとで構成されている。
このような構成において、図示しない監視カメラ２３からの映像出力を、携帯した表示装置に表示して、監視カメラ２３が所定方向に取付けられているかを確認し、取付け方向に若干のずれを生じている場合は、上記のように、監視カメラ２３を回転軸２１ａを中心とする前後方向および、または回転軸２２ａを中心とする左右方向に固定用ネジ２１ｃ、２２ｃにて調整を可能とし、ずれを補正して固定されるものであった。

【発明が解決しようとする課題】
しかしながら、図７の角度調整が可能な装置では、図５や図６の角度調整が可能な装置に対し簡単な構成になるものの、組立て部品点数は変らず、カメラ本体を含めた専有スペースを依然として広くとるものであった。
このため、上記のような取付け方向のずれを調整するために、組立て部品を共通化してカメラを取付けた後の専有スペースをとらず、安価に構成したものが望まれていた。
【０００７】
本発明は、上記の問題点に鑑みなされたもので、取付け方向のずれを調整するための組立て部品を共通化してカメラを取付けた後の専有スペースを小さくし、安価に構成することができる電子機器の角度調整装置を提供することを目的とするものである。
【０００８】
【課題を解決するための手段】
請求項１の発明は、天井面に取付けられ、左右両側に挿通孔および第一ネジ孔を形成した取付ベース板と、この取付ベース板に水平に取付けられ、前記第一ネジ孔に対応する左右に延びる一対の第一調整用長孔を備えた第一調整板と、この第一調整板の一側端に連結手段を介して回動自在に連結され、下部中央に上下に延びる軸用の長孔と、この長孔に並行に、且つ同長孔の短手方向の長さよりも大きい、短手方向の長さを有する第二調整用長孔とを備えた第二調整板とから構成される一対の角度設定板と、この一対の角度設定板の前記第二調整板の間に挟着され、前記長孔に対応するネジ孔と、前記第二調整用長孔に対応する第二ネジ孔とを両側面に備えた電子機器とから構成され、前記電子機器を、前記角度設定板の各長孔にネジを挿通し、前記電子機器および前記取付ベース板の各ネジ孔に螺着することにより挟着した後、ネジを緩めて前記各長孔の可動範囲内で前記電子機器を傾動させ、ネジ止めの位置を変更することにより、前記電子機器の左右および、または前後方向の設定角度を調整可能としたことを特徴とするものである。
【０００９】
このような構成においては、角度設定板が左右対称な共通部品として使用できるため、従来例の取付け方向のずれを調整するものに比べ、取付ベース板や電子機器とのネジ止めを迷わずに行なえ、安価に構成することができる。
また、角度設定板を夫々異なる構成部品とせずに左右対称に、取付ベース板に直接ネジ止めすることとしたので、従来例の調整装置と比べ、前後方向と左右方向を調整するための構成部品を、上下または交叉するように結合する必要がなく、電子機器を取付けた後の専有スペースをその分小型化することができる。
【００１０】
請求項２に記載の発明は、請求項１に記載の発明において、更に、組立ての手作業時に、電子機器に対する角度設定板の挟着方向を気に留めることなく、組立ての手間をかけないようにするために、前記長孔と並行に、且つ同長孔の両側に、前記第二調整用長孔を備えたことを特徴とするものである。
【００１１】
【発明の実施の形態】
以下、本発明の一実施形態例を図面を用いて説明する。
図１は本発明による電子機器の角度調整装置の構成要素の分解斜視図を示すもので、図１において、１は取付ベース板、２は角度設定板、３は撮像素子を内蔵した監視カメラからなる電子機器である。
【００１２】
取付ベース板１は、例えば、矩形状の金属板からなり、その金属板の左右両側を折曲してフランジを設け、フランジ内に一対の挿通孔１ａを形成し天井に取付けられる取付部１ｂと、フランジ外に挿通孔１ａと並行に一対の第一ネジ孔１ｃを形成した固定部１ｄとから構成されている。
【００１３】
角度設定板２は、例えば、取付ベース板１と同様に、矩形状の２枚の金属板を回動自在に連結するヒンジ部からなる連結手段２ｆで連結したものからなり、一方の金属板が取付ベース板１に水平に取付けられ、他方の金属板が連結手段２ｆを介して回動自在に連結され、後述する電子機器３に取付けられる。
具体的には、取付ベース板１に水平に取付けられ、前記第一ネジ孔１ｃに対応する左右に延びる一対の第一調整用長孔２ａを備えた第一調整板２ｂと、この第一調整板２ｂの一側端に連結手段２ｆを介して回動自在に連結され、下部中央に上下に延びる軸用の長孔２ｃと、この軸用の長孔２ｃに並行して左右両側に、軸用の長孔２ｃの短手方向の長さよりも大きい、短手方向の長さを有する第二調整用長孔２ｄとを備えた第二調整板２ｅとから構成され、この角度設定板２が、取付ベース板１に左右対称に配置される。
【００１４】
電子機器３は、例えば、直方体状の箱体からなり、一対の角度設定板２の第二調整板２ｅの間に挟着され、軸用の長孔２ｃに対応するネジ孔３ａと、第二調整用長孔２ｄに対応する第二ネジ孔３ｂとを両側面に形成した構成となっている。これらのネジ孔３ａと第二ネジ孔３ｂの開口位置は、電子機器３の上面が、取付ベース板１に対して所要の距離を備え、電子機器３の取付け方向のずれを調整可能な位置としている。
前記電子機器３を前記角度設定板２を介し前記取付ベース板１に取付けた後にネジを緩めて、前記第一調整用長孔２ａ、前記長孔２ｃおよび前記第二調整用長孔２ｄの可動範囲内で前記電子機器３を傾動させかつ前記連結手段２ｆの回動を利用してネジ止めの位置を変更することにより前記電子機器３の左右および、または前後方向のずれを調整可能としている。
【００１５】
図２は本発明による電子機器の角度調整装置の天井取付時の状態を示すもので、（ａ）は図１の構成要素を組立てた斜視図、（ｂ）は（ａ）のＡ矢視図、（ｃ）は（ａ）のＢ矢視図、（ｄ）は（ｃ）のＣ矢視図である。
【００１６】
次に、本発明の実施形態例の作用を図１及び図２を併用して説明する。
電子機器３のネジ孔３ａ、第二ネジ孔３ｂに、第二調整板２ｅの軸用の長孔２ｃと第二調整用長孔２ｄを合わせて、第二調整板２ｅの軸用の長孔２ｃと第二調整用長孔２ｄからネジ４と第二調整ネジ５を挿通し螺合すると、電子機器３が両側面から２個の角度設定板２により挟持される。
【００１７】
電子機器３を挟持した角度設定板２は、連結手段２ｆの回動により略９０度に折曲させて第一調整板２ｂの第一調整用長孔２ａを取付ベース板１の第一ネジ孔１ｃに合わせ、第一調整ネジ６を挿通しネジ止めすることによって、取付ベース板１に固定される。
【００１８】
取付ベース板１は、取付部１ｂの挿通孔１ａから図示しない固定手段を挿通し天井に固定される。
このように、上記の組立て手順によって、本発明の電子機器の角度調整装置が図２（ａ）の状態に組立てられる。図２（ｂ）（ｃ）（ｄ）に示すように、電子機器３の監視方向が天井面に対して垂設した状態に組立てられる。
図２（ｂ）に示すように、ネジ４と第二調整ネジ５を緩めて軸用の長孔２ｃと第二調整用長孔２ｄ内を回動して、電子機器３をａ方向に傾動させ、また、図２（ｃ）に示すように、第一調整ネジ６を緩めて第一調整用長孔２ａ内を平行移動し、かつ、ネジ４と第二調整ネジ５を緩めて軸用の長孔２ｃと第二調整用長孔２ｄ内を回動して、電子機器３をｂ方向に傾動させることにより、電子機器３の角度を調整することが可能である。
図２（ｂ）、図２（ｃ）に示される各ネジの機能は次の通りである。
ネジ４は、軸用の長孔２ｃ内でその位置を可変できる中心軸として電子機器３を傾動すると共に、電子機器３を角度設定板２の第二調整板２ｅに固定するものである。
第二調整ネジ５は、電子機器３の前後方向と左右方向、つまりａ方向とｂ方向の角度を調整するとともに、電子機器３を角度設定板２の第二調整板２ｅに固定するものである。
ａ方向の場合は、ネジ４を中心として、第二調整用長孔２ｄ内で第二調整ネジ５の位置を可変することによって調整され、ｂ方向の場合は、左側の角度設定板２の第二調整板２ｅの軸用の長孔２ｃおよび第二調整用長孔２ｄの長手方向と、右側の角度設定板２の第二調整板２ｅの軸用の長孔２ｃおよび第二調整用長孔２ｄの長手方向とを組合せた、範囲内でネジ４と第二調整ネジ５の位置を可変することによって調整されて、電子機器３を角度設定板２の第二調整板２ｅに固定するものである。
第一調整ネジ６は、第二調整ネジ５と共にｂ方向の角度を調整するために利用され、第一調整用長孔２ａ内で第一調整ネジ６の位置を可変することによって電子機器３を平行移動すると共に、角度設定板２の第一調整板２ｂを取付ベース板１に固定するものである。
更に、ネジ４、第二調整ネジ５および第一調整ネジ６は、平座金とバネ座金を備え螺着するものとし、電子機器３の取付け方向のずれを調整するため各ネジを緩めた場合に、電子機器３の位置が急に変化しないよう、角度設定板２と取付ベース板１との間、電子機器３と角度設定板２との間に摩擦力をもたせ、また、電子機器３、角度設定板２および取付ベース板１が固定された場合に、各ネジが緩んで電子機器３の固定位置が変化しないよう、緩み止めとして作用する。
このように、本発明の電子機器の角度調整装置においては、同一の角度設定板２を２つ使用しているため、従来例と比べて、組み立ての際の部品を共通化することができ、電子機器３を取付ベース板１と角度設定板２により取付けた状態から、角度設定板２の角度調整機能によって手作業による取付方向のずれの調整を集中して行なうことができる。
また、２つの方向の角度を調整する場合に、構成の異なる別部品とすることがないため、従来例の調整装置と比べ、前後方向と左右方向を調整するための構成部品を、上下または交叉するように結合させる専有スペースを設ける必要がなくなり、電子機器３を取付けた後の専有スペースをその分小型化することができる。
【００１９】
図３は、図２の天井取付時の状態の一部分を示すもので、（ａ）は図２（ｄ）の第一調整用長孔２ａ付近を示し、（ｂ）は図２（ｂ）の軸用の長孔２ｃと第二調整用長孔２ｄ付近を示し、（ｃ）は軸用の長孔２ｃと第二調整用長孔２ｄによる角度の可動範囲を示す概略図、図４は、本発明による電子機器の角度調整装置の電子機器３を斜めに傾けて固定した状態を示す側面図である。
【００２０】
次に、本発明の実施形態例の角度を調整する場合の作用を図３及び図４を併用して説明する。
図３（ａ）のように、第一調整ネジ６が、第一調整用長孔２ａに挿通され、取付ベース板１の第一ネジ孔１ｃにネジ止めされている状態を示すものである。
この状態から、第一調整ネジ６を、取付ベース板１の第一ネジ孔１ｃから抜け落ちないように緩めて、第一調整用長孔２ａの長手方向に対して角度設定板２の第一調整板２ｂを可動させて連結手段２ｆの中心軸の位置が変更でき、取付けベース板１と角度設定板２の第一調整板２ｂと第一調整ネジ６の位置関係が変更されることとなる。
このとき、ネジ４、第二調整ネジ５も電子機器３のネジ孔３ａ、第二ネジ孔３ｂから抜け落ちないように緩めておき、軸用の長孔２ｃ、第二調整用長孔２ｄの長手方向に対して角度設定板２の第二調整板２ｅを可動しておき、電子機器３の角度を図２（ｃ）のｂ方向に調整することができる。
ここで、第二調整用長孔２ｄと同様に、軸用の孔を長孔としたことにより、ｂ方向の調整を可能としている。
【００２１】
図３（ｂ）のように、電子機器３に固定される角度設定板２の第二調整板２ｅに備える第二調整用長孔２ｄの短手方向の長さＬを、回動軸を兼ねた軸用の長孔２ｃの短手方向の長さＭより大きくし、ネジ４と第二調整ネジ５は、この長さＭに対し挿通可能な直径のネジ部を形成している。
これによって、ネジ４と第二調整ネジ５を緩めた状態で、第二調整用長孔２ｄの長手方向に対して回動軸を兼ねた軸用の長孔２ｃに仮止めされたネジ４を中心として、電子機器３の角度を図２（ｂ）のａ方向に調整することがきる。
ここで、図３（ｃ）のように、例えば、第二調整用長孔２ｄの短手方向の真中に第二調整ネジ５のネジ部が位置するように、第二調整用長孔２ｄと軸用の長孔２ｃとの短手方向間隔が設けられた角度設定板２の第二調整板２ｅにおける、電子機器３の可動範囲を説明すると、ネジ４のネジ部が軸用の長孔２ｃの長手方向の真中に位置する場合、そのネジ４のネジ部の位置を中心とした、第二調整ネジ５のネジ部の、第二調整用長孔２ｄの長手方向の点線で示すネジ部のそれぞれの位置とネジ４のネジ部の位置を結ぶ角度Ａが電子機器３の可動範囲となる。
また、ネジ４のネジ部が軸用の長孔２ｃの長手方向の上端に位置する場合、そのネジ４のネジ部の位置を中心とした、第二調整ネジ５のネジ部の、第二調整用長孔２ｄの長手方向の上端に当接する点線で示すネジ部の位置と上端と下端の間の点線で示すネジ部の位置とを結ぶ角度Ｂが可動範囲となる。
更に、ネジ４のネジ部が軸用の長孔２ｃの長手方向の下端に位置する場合は、ネジ４のネジ部の位置を中心とした、第二調整ネジ５のネジ部の、第二調整用長孔２ｄの長手方向の下端に当接する点線で示すネジ部の位置と上端と下端の間の点線で示すネジ部の位置とを結ぶ角度Ｃが可動範囲となる。
このように、電子機器３に固定される、角度設定板２の第二調整板２ｅに備える回動軸を兼ねた軸用の長孔２ｃとしたので、丸孔と比較して、第二調整用長孔２ｄとの連動によって、電子機器３の調整可動範囲を大きくできる。
更に、図３（ｂ）のように、電子機器３に固定される角度設定板２の第二調整板２ｅに備える第二調整用長孔２ｄを、回動軸を兼ねた軸用の長孔２ｃを中心とする左右両側に２個所に設けた場合には、角度設定板２は、左右対称な構成部品とすることができるため、組立ての手作業時に、電子機器３に対する角度設定板２の取付方向を気に留める必要がなくなり、組み立ての手間をかけないようにすることができる。
【００２２】
図４は、図２（ｃ）のｂ方向に電子機器３の角度を変更させた場合の図３の説明の具体例である。
角度設定板２の軸用の長孔２ｃの長手方向の範囲内で、例えば、ｆ方向から見た、左側の角度設定板２の第二調整板２ｅでは、軸用の長孔２ｃの上端でネジ４と第二調整ネジ５を固定し、ｇ方向から見た、右側の角度設定板２の第二調整板２ｅでは、軸用の長孔２ｃの下端でネジ４と第二調整ネジ５を固定して左右方向の角度を左に傾けて取付けたものである。
この変更の際の角度設定板２の取付ベース板１上での位置変化は、図３（ａ）のとおり、第一調整板２ｂを第一調整用長孔２ａにより可動させ調整することで、図２（ｃ）のｂ方向の変更を実現している。
【００２３】
前記実施形態例では、電子機器３を監視カメラとした場合について説明したが、本発明はこれに限るものでなく、スピーカ、赤外線センサ等の検出装置、スポットライト等の照明機器、ＰＤＰ（プラズマディスプレイパネル）やＬＣＤパネル等の平面型表示装置等の角度の調整を必要とする電子機器とした場合についても利用することができる。
【００２４】
前記実施形態例では、取付ベース板１の左右両側を折曲してフランジを設け、このフランジを境界に挿通孔１ａを備える取付部１ｂと第一ネジ孔１ｃを備える固定部１ｄとから構成された場合について説明したが、本発明はこれに限るものでなく、取付ベース板１にフランジを設けず、取付ベース板１の左右両側に並列に挿通孔１ａと第一ネジ孔１ｃを設けた場合も利用することができる。
【００２５】
前記実施形態例では、取付ベース板１と角度設定板２を矩形状の金属板とした場合について説明したが、本発明はこれに限るものでなく、角度の調整を必要とする各種の電子機器に応じて矩形状の金属板でなくてもよく、例えば、半円状の金属板とした場合にも利用することができる。
【００２６】
前記実施形態例では、電子機器３の大きさに対応した取付ベース板１、角度設定板２の大きさとした場合について説明したが、本発明はこれに限るものでなく、取付ベース板１には、第一調整用長孔２ａを複数組設けたり、角度設定板２には、電子機器３の両側面に、軸用の長孔２ｃと第二調整用長孔２ｄを複数組設けたりして、角度の調整を必要とする複数種の電子機器に対応してもよく、また、取付ベース板１と角度設定板２のセットを各種の電子機器に対応してもよく、適宜選択して利用することができる。
【００２７】
前記実施形態例では、第二調整板２ｅにおいて、下部中央に軸用の長孔２ｃとこの軸用の長孔２ｃに並行に左右両側に第二調整用長孔２ｄを形成した場合について説明したが、本発明はこれに限るものでなく、第二調整板２ｅの下部に垂直方向に並行に軸用の長孔２ｃと第二調整用長孔２ｄを一つだけ形成した場合も利用することができる。
【００２８】
前記実施形態例では、角度調整装置の組立て手順が取付ベース板１を天井に固定することを最後とした場合について説明したが、本発明はこれに限るものでなく、この逆の手順の場合も利用することができる。
【００２９】
前記実施形態例では、取付ベース板１は天井に取付けられ、角度設定板２は取付ベース板１に水平に取付けられる場合について説明したが、本発明はこれに限るものでなく、取付ベース板１が壁面、柱等に取付けられ、角度設定板２が取付けベース板１に垂直に取付けられる場合も利用することができる。
【００３０】
前記実施形態例では、角度設定板２の第一調整板２ｂと第二調整板２ｅとをヒンジ部で連結する場合について説明したが、本発明はこれに限るものでなく、第一調整板と第二調整板とを回動自在に連結する手段を利用することにより実施できる。
【００３１】
【発明の効果】
請求項１に記載の発明は、天井面に取付けられ、左右両側に挿通孔および第一ネジ孔を形成した取付ベース板と、この取付ベース板に水平に取付けられ、前記第一ネジ孔に対応する左右に延びる一対の第一調整用長孔を備えた第一調整板と、この第一調整板の一側端に連結手段を介して回動自在に連結され、下部中央に上下に延びる軸用の長孔と、この長孔に並行に、且つ同長孔の短手方向の長さよりも大きい、短手方向の長さを有する第二調整用長孔とを備えた第二調整板とから構成される一対の角度設定板と、この一対の角度設定板の前記第二調整板の間に挟着され、前記軸用の長孔に対応するネジ孔と、前記第二調整用長孔に対応する第二ネジ孔とを両側面に備えた電子機器とから構成され、前記電子機器を、前記角度設定板の各長孔にネジを挿通し、前記電子機器および前記取付ベース板の各ネジ孔に螺着することにより挟着した後、ネジを緩めて前記各長孔の可動範囲内で前記電子機器を傾動させ、ネジ止めの位置を変更することにより、前記電子機器の左右および、または前後方向の設定角度を調整可能としたことを特徴とする。
【００３２】
このような構成においては、角度設定板が左右対称な共通部品として使用できるため、従来例の取付け方向のずれを調整するものに比べ、取付ベース板や電子機器とのネジ止めを迷わずに行なえ、安価に構成することができる。
また、角度設定板を夫々異なる構成部品とせずに左右対称に、取付ベース板に直接ネジ止めすることとしたので、従来例の調整装置と比べ、前後方向と左右方向を調整するための構成部品を、上下または交叉するように結合する必要がなく、電子機器を取付けた後の専有スペースをその分小型化することができる。
【００３３】
請求項２に記載の発明は、請求項１に記載の発明において、前記長孔と並行に、且つ同長孔の両側に、前記第二調整用長孔を備えたので、組立ての手作業時に、電子機器に対する角度設定板の挟着方向を気に留めることなく、組立ての手間をかけないようにすることができる。
