【発明の属する技術分野】
この発明は、例えば、デジタルスチールカメラ等のストロボ装置に関する。
【０００２】
【従来の技術】
ストロボ装置は、閃光放電管、トリガーコイル、スイッチング素子及びコンデンサ等の構成部品で構成され、これら構成部品は、プリント基板に搭載されるとともに、電気的に接続されている。トリガーコイルは、通常トリガーリード線を介して閃光放電管に接続され、トリガー電圧の印加を行っている。
【０００３】
しかし、トリガーリード線には高電圧が供給されることから、他の電子部品に対してノイズ対策、絶縁対策を行なう必要があり、ストロボ装置の組立て時にはトリガーリード線の配線処理に注意を払っており、工程数が増加してコストアップの原因となっている。
【０００４】
そこで、従来、閃光放電管を反射笠の開口内に挿通した後、反射笠を光学パネルに係合固定するとともに、光学パネルをプリント基板と係合固定する。さらに、光学パネルにトリガー接片を装着し、さらに閃光放電管の一対の主電極と電極接片間及びトリガー接片とトリガーコイルの出力端間をそれぞれ電気的に接続し、配線作業の簡素化を図った技術が知られている（例えば、特許文献１参照）。

【０００６】
【発明が解決しようとする課題】
しかしながら、特許文献１は、プリント基板に光学パネルを固定するための切欠部を設け、この切欠部に反射笠を含む閃光放電管を装着するとともに、この閃光放電管とプリント基板に搭載したトリガーコイルとをトリガー接片によって接続した構造である。従って、プリント基板に閃光放電管とトリガーコイルとを組み込むとともに、電気的に接続するものは知られているが、光電量等を制御するスイッチング素子、コンデンサ等の電子部品を閃光放電管とトリガーコイルとともに、ユニット化したものは知られていない。
【０００７】
この発明は、前記事情に着目してなされたもので、その目的とするところは、少なくとも閃光放電管、トリガーコイル及びスイッチング素子をユニット化してコンパクトに構成するとともに、配線の簡素化を図り、組立作業性の向上を図ることができるストロボ装置を提供することにある。

【０００９】
請求項２は、請求項１の前記第１と第２の基板挟持部は、第１及び第２の端子の一部を引き起こした一対の舌片からなり、この舌片が前記支持脚を貫通して前記構成ブロック収納部に突出し、サブプリント基板を挟持することを特徴とする。
