<P>PROBLEM TO BE SOLVED: To provide a device which detects whether an elevator door is closing normally or not. <P>SOLUTION: A proximal sensor 2 is provided at an end of the door opening of a high speed door 1L of a cage, and a bending part 3 is formed at an end of the door closing of a low speed door 2L of the cage. When all doors 1L, 1R, 2L, 2R are in closed state, the proximal sensor 2 detects the state of the bending part 3 and determines that the relative positions of the high speed door 1L and the low speed door 2L are normal and confirms the door of each cage is closed normally. <P>COPYRIGHT: (C)2013,JPO&INPIT |
