<p>PROBLEM TO BE SOLVED: To reduce labor of an operator required to fix a landing panel in an opened state.SOLUTION: The landing door device of an elevator is provided with: a locking device 10 that locks a landing door panel 4 by inhibiting a door hanger 6 from moving toward a direction of opening the landing door panel 4; and an insertion portion 13 that guides a key 14, which performs unlocking operation on the locking device 10, to the locking device 10. The landing door device of an elevator comprises: a detecting device 15 that detects the key 14 inserted into the insertion portion 13; a roller braking device 20 that inhibits rolling of hanger rollers 6a on a door rail 3; and a control device 30 that controls the roller braking device 20. The control device 30 directs the roller braking device 20 to allow the hanger rollers 6a to roll on the door rail 3 while the detecting device 15 is detecting the key 14, and directs the roller braking device 20 to inhibit the hanger rollers 6a from rolling on the door rail while the detecting device 15 is not detecting the key 14.</p> |
