PROBLEM TO BE SOLVED: To make it possible to drive opening and closing of a landing door 3 by a drive unit 8 for elevation which rotationally drives a screw shaft 6.SOLUTION: A screw shaft 6 is located in a hoistway 1, and a movable floor 5 is elevated by rotational driving by a drive unit 8. An entrance 2 has a landing door 3, and the door is opened and closed by the drive unit 8 via a door opening/closing mechanism 11, 12. The door opening/closing mechanism 11, 12 comprises a door drive shaft 14, an intermediate shaft 15, a pulley shaft 16, an electromagnetic clutch mechanism 18 and a bi-directional ratchet mechanism 17. A drive pulley 19 for the pulley shaft 16 is in linkage with a door operator. When the screw shaft 6 is caused to perform reciprocating rotary motion at a very small angle by the drive unit 8 at a prescribed floor position, the drive pulley 19 is rotated in one direction by the ratchet mechanism 17, and the landing door 3 is opened.SELECTED DRAWING: Figure 1

    【課題】スクリューシャフト6を回転駆動する昇降用の駆動装置8でもって乗り場ドア3を開閉駆動できるようにする。【解決手段】昇降路1内にスクリューシャフト6が配置され、駆動装置8による回転駆動によって可動床5が昇降する。乗降口2は乗り場ドア3を有し、ドア開閉機構11,12を介して駆動装置8によって開閉される。ドア開閉機構11,12は、ドア駆動シャフト14と、中間シャフト15と、プーリシャフト16と、電磁クラッチ機構18と、双方向のラチェット機構17と、を備え、プーリシャフト16の駆動プーリ19がドアオペレータに連動する。所定のフロア位置にあるときに駆動装置8によりスクリューシャフト6を微小角度で往復回転運動させると、ラチェット機構17によって駆動プーリ19が一方向に回転し、乗り場ドア3が開く。【選択図】図1
