Description

【０００１】
【発明の属する技術分野】
本発明は複数の発光手段の夫々に対向配置される複数の光透過部が一体成形された光透過部材をパネルに取り付ける光透過部材取付構造に関する。
【０００２】
【従来の技術】
例えば、図９に示されるように、筐体１の内部に回路基板（図示せず）が収納された電子装置２においては、筐体１の前面パネル３に複数の表示灯４ａ〜４ｅが配設されている。この表示灯４ａ〜４ｅは、筐体１の内部に光源が設けられ、前面パネル３に透明材により形成された透過部を有する光透過部材取付構造となっている。
【０００３】
図１０は従来の光透過部材取付構造の一例を示す斜視図である。
図１０に示されるように、従来の光透過部材取付構造は、回路基板（図示せず）に設けられた複数の発光手段としての発光ダイオード（発光ダイオード）５ａ〜５ｅと、該複数の発光ダイオードの夫々に対向配置される複数の光透過部６ａ〜６ｅが透明アクリル材により一体成形された光透過部材７と、前面パネル３に設けられた複数の取付孔８ａ〜８ｅと、を備えてなる。また、光透過部材７の固定方法としては、前面パネル３の取付孔８ａ〜８ｅに光透過部６ａ〜６ｅを嵌め込む方法が採られている。
【０００４】
この構成では、複数の光透過部６間がＳ字状に湾曲形成されたヒンジ９により連結されている。従って、複数の光透過部６ａ〜６ｅは、ヒンジ９を介して前面パネル３に設けられた取付孔８ａ〜８ｅに対向する間隔に保持されている。
【０００５】
また、ヒンジ９は、取付孔８ａ〜８ｅの挿入方向（Ｘ方向）に薄く、前面パネル３と平行な方向（Ｙ方向）に湾曲部分が変形可能な構成となっており、複数の光透過部６を各取付孔８ａ〜８ｅに挿入する際の位置合わせが容易に行えるようになっている。
【０００６】
【発明が解決しようとする課題】
しかしながら、上記のような従来の構成では、ヒンジ９がどの方向にも変形できる形状に形成されているので、例えば、複数の光透過部６ａ〜６ｅを各取付孔８ａ〜８ｅに圧入した後、前面パネル３の前面側から各取付孔８ａ〜８ｅから突出した光透過部６の先端を押圧すると、光透過部６ａ〜６ｅが前面パネル３の内側に脱落してしまう場合があり、その場合前面パネル３の前面側から元に戻すことができず、前面パネル３を外して内側から再挿入させるといった面倒な作業が必要になるという問題があった。
【０００７】
そこで、本発明は上記課題を解決した光透過部材取付構造を提供することを目的とする。
【０００８】
【課題を解決するための手段】
本発明は上記課題を解決するため、以下のような特徴を有する。
【０００９】
上記請求項１記載の発明は、複数の光透過部の夫々を取付孔に挿入する方向へ移動できず、パネルの平面と平行な二方向へ回動できるように支持する支持部を光透過部材に設けたものであり、光透過部の夫々を取付孔に挿入した後で光透過部が外側から押圧された際に取付孔から脱落することを防止できる。
【００１０】
詳しくは、支持部がパネルの平面と平行な方向に薄く、取付孔に挿入する方向に厚い形状に形成されたものであり、光透過部の夫々を取付孔に挿入した後で光透過部が外側から押圧された際に取付孔から脱落することを防止できる。
【００１１】
上記請求項２記載の発明は、支持部が光透過部の両側で平行に配された第１の板状部材と、光透過部と第１の板状部材との間を連結する第２の板状部材と、からなるものであり、光透過部の夫々を取付孔に挿入した後で光透過部が外側から押圧された際に取付孔から脱落することを防止できる。
【００１２】
上記請求項３記載の発明は、支持部が光透過部の両側で平行に配された第１の板状部材と、第１の板状部材と光透過部との間で屈曲されて、第１の板状部材と光透過部との間を連結する第２の板状部材と、からなるものであり、光透過部の夫々を取付孔に挿入した後で光透過部が外側から押圧された際に取付孔から脱落することを防止できる。
【００１３】
【発明の実施の形態】
以下、図面と共に本発明の一実施例について説明する。
図１（Ａ）（Ｂ）は本発明になる光透過部材取付構造の一実施例を示す正面図、側面図である。
図１（Ａ）（Ｂ）に示されるように、光透過部材取付構造１０は、回路基板１２に設けられた複数の発光手段としての発光ダイオード（ＬＥＤ：Light Emitting Diode）１４ａ〜１４ｅと、該複数の発光ダイオード１４ａ〜１４ｅの夫々に対向配置される円柱形状の光透過部１６ａ〜１６ｅが一体成形された光透過部材１８と、前面パネル２０に設けられた複数の取付孔２２ａ〜２２ｅと、を備えてなる。各取付孔２２ａ〜２２ｅは、回路基板１２に配置された発光ダイオード１４ａ〜１４ｅ及び各光透過部１６ａ〜１６ｅが嵌合する間隔で設けられている。
【００１４】
図２は光透過部材１８の構成を示す図であり、（Ａ）は平面図，（ｂ）は側面図（Ｃ）は底面図、（Ｄ）はＩ−Ｉ断面図、（Ｅ）はII−II断面図、（Ｆ）III−III断面図である。
図２（Ａ）〜（Ｆ）に示されるように、光透過部材１８は、取付孔２２ａ〜２２ｅ及び発光ダイオード１４ａ〜１４ｅに対応する間隔で複数の光透過部１６ａ〜１６ｅが一列に並んだ状態で透明アクリル材により一体成形されている。複数の光透過部１６ａ〜１６ｅは、取付孔２２ａ〜２２ｅより小径な小径部１６ａ_１〜１６ｅ_１と発光ダイオード１４ａ〜１４ｅの外径と略同径な大径部１６ａ_２〜１６ｅ_２とを有する。また、小径部１６ａ_１〜１６ｅ_１は、取付孔２２ａ〜２２ｅに挿入された際、前面パネル２０の表面２０ａ側に若干突出する長さ寸法に形成されており、大径部１６ａ_２〜１６ｅ_２は、取付孔２２ａ〜２２ｅより大径で、且つ端部が発光ダイオード１４ａ〜１４ｅの先端に近接する長さ寸法に形成されている。
【００１５】
また、光透過部材１８は、光透過部１６ａ〜１６ｅの小径部１６ａ_１〜１６ｅ_１が取付孔２２ａ〜２２ｅに挿入された後、取付ねじ（図示せず）により前面パネル２０の裏面２０ｂに固定される固定部２４が複数箇所に設けられている。このように、光透過部材１８は、固定部２４が複数箇所に設けられているので、光透過部１６ａ〜１６ｅの周辺以外の部位の剛性が高くなっている。
【００１６】
さらに、光透過部材１８は、複数の光透過部１６ａ〜１６ｅを支持する支持部２６を有する。この支持部２６は、前面パネル２０の延在方向（Ｘ方向）に延在する第１の支持部２８，３０と、平行に配された支持部２８，３０間で直交方向（Ｙ方向）に横架された第２の支持部３２，３４とを有する。
【００１７】
図３は光透過部材１８の一部を拡大して示す斜視図である。図４は手前側の第１の支持部３０を省略して示す斜視図である。
図３及び図４に示されるように、第１の支持部２８，３０は、前面パネル２０に対して光透過部１６ａ〜１６ｅを取付孔２２ａ〜２２ｅに挿入するＺ方向に厚く形成され、前面パネル２０と平行なＹ方向に薄く形成されている。従って、第１の支持部２８，３０は、Ｚ方向への変位が制限されると共に、厚さ寸法の薄いＡ方向（前面パネル２０を正面からみて左右方向）に弾性変形して回動変位できるように設けられている。
【００１８】
また、第２の支持部３２，３４は、上記第１の支持部２８，３０よりも小さく形成されており、前面パネル２０に対して光透過部１６ａ〜１６ｅを取付孔２２ａ〜２２ｅに挿入するＺ方向に厚く形成され、前面パネル２０と平行なＸ方向に薄く形成されている。従って、第１の支持部２８，３０は、Ｚ方向への変位が制限されると共に、厚さ寸法の薄いＢ方向（前面パネル２０を正面からみて上下方向）に弾性変形して回動変位できるように設けられている。
【００１９】
よって、光透過部１６ａ〜１６ｅは、第１の支持部２８，３０及び第２の支持部３２，３４によりＺ方向への変位ができないと共に、Ａ方向及びＢ方向に変位可能に支持されている。これにより、光透過部１６ａ〜１６ｅの小径部１６ａ_１〜１６ｅ_１の位置を前面パネル２０に設けられた取付孔２２ａ〜２２ｅに挿入する位置に調整することができる。
【００２０】
また、光透過部１６ａ〜１６ｅは、取付孔２２ａ〜２２ｅに挿入された小径部１６ａ_１〜１６ｅ_１が前面側から押圧されても第１の支持部２８，３０及び第２の支持部３２，３４によりＺ方向への変位ができないので、小径部１６ａ_１〜１６ｅ_１が取付孔２２ａ〜２２ｅから脱落することが防止される。
【００２１】
尚、光透過部材１８の中央に設けられた光透過部１６ｂは、取り付け時の基準位置となるため、第２の支持部３２，３４のＺ方向の長さ寸法が同一寸法に形成されている。そのため、光透過部１６ｂは、Ｚ方向及びＡ方向及びＢ方向に変位できないようにどの方向にも剛性の高い状態で支持されている。
【００２２】
また、光透過部材１８は、前面パネル２０の裏面２０ｂに固定される固定部２４により剛性の高い部材の一部に剛性の低い第１の支持部２８，３０及び第２の支持部３２，３４を介して光透過部１６ａ〜１６ｅを支持する構成であるので、部品全体として剛性を高くすることができ、組立作業時の取り扱いがしやすくなっている。
【００２３】
次に、本発明の変形例について説明する。
図５（Ａ）（Ｂ）は本発明の変形例を示す正面図、側面図である。

【００２５】
また、光透過部材４８は、光透過部４６ａ〜４６ｅの小径部４６ａ_１〜４６ｅ_１が取付孔５２ａ〜５２ｅに挿入された後、取付ねじ（図示せず）により前面パネル５０の裏面５０ｂに固定される固定部５４が複数箇所に設けられている。
【００２６】
さらに、光透過部材４８は、複数の光透過部４６ａ〜４６ｅを支持する支持部５６を有する。この支持部５６は、前面パネル５０の延在方向（Ｘ方向）に延在する第１の支持部５８，６０と、第１の支持部５８，６０と光透過部４６ａ〜４６ｅとの間を連結するようにＸ，Ｙ方向に横架された第２の支持部６２，６４とを有する。
【００２７】

【００２８】
また、第２の支持部６２，６４は、上方からみると、Ｌ字状に形成されており、Ｘ方向に形成された第１の腕部６２ａ，６４ａと、Ｙ方向に形成された第２の腕部６２ｂ，６４ｂと、を有する。第１の腕部６２ａ，６４ａ及び第２の腕部６２ｂ，６４ｂは、夫々第１の支持部５８，６０よりも小さく形成されており、前面パネル５０に対して光透過部４６ａ〜４６ｅを取付孔５２ａ〜５２ｅに挿入するＺ方向に厚く形成され、前面パネル５０と平行なＸ，Ｙ方向に薄く形成されている。
【００２９】
従って、第１の腕部６２ａ，６４ａは、Ｚ方向への変位が制限されると共に、厚さ寸法の薄いＡ方向（前面パネル５０を正面からみて左右方向）に弾性変形して回動変位できるように設けられている。また、第２の腕部６２ｂ，６４ｂは、Ｚ方向への変位が制限されると共に、厚さ寸法の薄いＢ方向（前面パネル５０を正面からみて上下方向）に弾性変形して回動変位できるように設けられている。
【００３０】
よって、光透過部４６ａ〜４６ｅは、第１の支持部５８，６０及び第２の支持部６２，６４によりＺ方向への変位ができないと共に、第１の腕部６２ａ，６４ａ及び第２の腕部６２ｂ，６４ｂによりＡ方向及びＢ方向に変位可能に支持されている。これにより、光透過部４６ａ〜４６ｅの小径部４６ａ_１〜４６ｅ_１の位置を前面パネル５０に設けられた取付孔５２ａ〜５２ｅに挿入する位置に調整することができる。
【００３１】
また、光透過部４６ａ〜４６ｅは、取付孔５２ａ〜５２ｅに挿入された小径部４６ａ_１〜４６ｅ_１が前面側から押圧されても第１の支持部５８，６０及び第２の支持部６２，６４の第１の腕部６２ａ，６４ａ及び第２の腕部６２ｂ，６４ｂによりＺ方向への変位ができないので、小径部４６ａ_１〜４６ｅ_１が取付孔５２ａ〜５２ｅから脱落することが防止される。
【００３２】
尚、光透過部材４８の中央に設けられた光透過部４６ｂは、取り付け時の基準位置となるため、第２の支持部６２，６４（第１の腕部６２ａ，６４ａ及び第２の腕部６２ｂ，６４ｂ）のＺ方向の長さ寸法が同一寸法に形成されている。そのため、光透過部４６ｂは、Ｚ方向及びＡ方向及びＢ方向に変位できないようにどの方向にも剛性の高い状態で支持されている。
【００３３】
