front door practiceとは 意味・読み方・使い方

To safely install a door with excellent workability by arranging one member bringing a pivot hinge to a locked state at a separate projecting position from a pinball lending machine in consideration of the difficult point that works are difficult to practice owing to the hindrance of the pinball lending machine projected on a front when a pinball machine board is attached pivotally to a door mounting member by the hinge.例文帳に追加

扉取付部材にピボットヒンジでパチンコ機盤を枢着する際、前面に突出の玉貸機が邪魔で作業しにくい難点に鑑み、玉貸機から離反突出の位置でヒンジがロック状態となる一部材を配し、開閉扉を作業性よく安全に取着可能とする。 - 特許庁
