Abstract

　複数本の光源ランプ間の間隔を中央部で狭く端部に向かうにしたがって広くする等のように、種々なる光源ランプ間の間隔を設定するのに必要なランプホルダの種類を減らすことができるランプホルダを提供すること。 　平板状のランプ収容面に取り付けられ、複数本の管形状の光源ランプ５を所定間隔に支持するランプホルダ２０のホルダ基板２１の両端寄り部位にそれぞれ３個のランプ挟持用ピン２２ａ，２２ｂ，２２ｃが突設され、各ランプ挟持用ピンは、いずれかのピン間を光源ランプ５が挿通可能な位置関係に配置され、ホルダ基板２１のランプ収容面４ａ内での回転角度の違いにより、ホルダ基板２１の両端寄り部位にそれぞれ挟持される光源ランプ５，５のランプ間間隔が異なるように構成されている。
