本発明は、例えばラップトップ型のパソコンやビデオカメラ等の本体部と液晶画面表示部との間に用いられる二軸ヒンジ装置に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
二軸ヒンジ装置は、第一部材に対して第二部材を公転回動自在にして自転回動自在に設けるものであるが、例えば、本体部に対して画面表示部を自転回動自在に設けつつ、本体部に対して折り畳み重合させる場合、この折り畳み時の画面表示部の自転回動位置を規制することが望ましい。
【０００３】
即ち、折り畳み収納する場合、画面表示部を折り畳み向きに向き直してから本体部へ回動して収納する必要があるが、この折り畳み向きにしない限り本体部へ回動し得ないようにすることで、画面表示部の損傷や配線の損傷，耐久性や品質保持を向上することができる。
