Abstract
Description
右目用及び左目用の一対の光シャッター、前記一対の光シャッターの駆動回路、前記一対の光シャッターの駆動用電源装置、前記一対の光シャッターをそれぞれの内側端部で支持するブリッジ、当該立体映像視聴装置を前記眼鏡に着脱自在に繋止する繋止部、並びに前記駆動回路及び前記電源装置を支持する支持部、を備え、
前記電源装置が、二次電池を含み、
前記繋止部及び前記支持部が、前記ブリッジと一体的に形成されており、
重心が、前記ブリッジに位置している、立体映像視聴装置に関する。
図1に、本発明の実施形態1に係る立体映像視聴装置を斜視図により示す。図2に、立体映像視聴装置の機能ブロック図を示す。
立体映像視聴装置(以下、視聴装置という)10は、アクティブ・シャッター方式の立体映像視聴システムに対応した、通常の眼鏡に装着するための視聴装置である。
図4に示すように、二次電池28は、有底円筒形の電池ケース51、電池ケース51内に収容された捲回型電極群52、および電池ケース51を封止する絶縁ガスケット61を備えている。電池ケース51の外側面は絶縁カバー54で覆われている。
電極群52は、導電性を有する巻芯55と、負極56と、正極57と、負極56と正極57との間を隔離するセパレータ58とを備えている。この電極群52には、非水電解質が接触している。
巻芯55の一端59は、電池ケースの外部に露出され、負極端子として用いられる。巻芯55の一端は、絶縁ガスケット61の孔に圧入されている。巻芯55の他端には、電池ケース51と短絡しないように、絶縁キャップ60が取付けられている。
負極56は、帯状の負極集電体、および負極集電体の両面に形成された負極活物質層を有する。負極56の総厚みは、35~150μmが好ましい。
負極56の一端部に、集電体21の両面において負極活物質層が形成されず負極集電体が露出する部分が形成されている。この部分が、巻芯55に溶接されている。
負極集電体には、使用される負極活物質の充放電時の電位範囲において化学変化を起こさない材質が用いられる。
蒸着法にて負極集電体の表面に容量密度の高い珪素を含む薄膜を形成する場合、容量密度が1200~1300mAh/cm3程度の高い負極活物質が得られる。小型電池でも、高エネルギー密度化により、高容量を有する電池が得られる。
正極集電体には、帯状の金属箔が用いられ、好ましくは、アルミニウム箔またはアルミニウム合金箔である。
正極活物質層は、正極活物質を含み、さらに必要に応じて、正極導電剤および正極結着剤を含んでもよい。
