3 to 7, 13 is an elevator car, 14 is a car detection plate made of a permanent magnet provided at the lower end of the car 13, and 15 is a car about 1000 mm above each landing floor that decelerates. Two DOWN deceleration detection sensors provided at a position immediately (immediately after the start) and away from the landing floor, with an interval of about 50 mm in the vertical direction as shown in FIG. The magnetic sensors A and B are arranged. Reference numeral 16 denotes an UP deceleration detection sensor provided at a position soon (immediately) after the car about 1000 mm below each landing floor starts to decelerate, and at a position away from the landing floor. As shown, two magnetic sensors A and B are arranged at an interval of about 50 mm in the vertical direction. The car detection plate 14, the DOWN deceleration detection sensor 15, and the UP deceleration detection sensor 16 constitute a car deceleration detection device. As for the installation positions of the deceleration detection sensors 15 and 16, as shown in FIG. 4, for example, when the rated speed of the elevator is 60 m / min or 45 m / min, the car approaches the stop floor, In order to detect that the vehicle is decelerating to the stopping speed, it is determined that the vehicle is decelerating to a speed of 40 to 35 m / min (average 37.25 m / min) at a position of about 1000 mm from the floor of the stop floor. It can be seen that this can be realized by installing the DOWN deceleration detection sensor 15 and the UP deceleration detection sensor 16 to be detected.

As shown in FIG. 6, two sensors with an interval of about 50 mm in the vertical direction are provided. In this configuration, magnetic sensors A and B are arranged. The car detection plate 17 and the UP / DOWN common deceleration detection sensor 18 constitute a car deceleration detection device.
As described above, a case where a permanent magnet is used for the car detection plate 17 and two magnetic sensors A and B are attached to the DOWN / UP common deceleration detection sensor 18 at intervals of 50 mm will be described as an example in FIG. As shown, in the UP operation, the time UTX from when the magnetic sensor B is turned on until the magnetic sensor A is turned on is 37.5 m / min = 31.25 mSec, and UTX ≦ 31.25 mSec. At that time, the elevator decides to pass without arriving and message B is not announced. On the other hand, when UTX > 31.25 mSec, it is determined that the elevator has arrived and the landing door is opened, and the message B is announced to the elevator landing 1. In the DOWN operation, the time DTX from when the magnetic sensor A is turned on to when the magnetic sensor B is turned on is 37.5 m / min = 31.25 mSec, when DTX ≦ 31.25 mSec. It is determined that the elevator passes without arriving, and message B is not announced. On the other hand, when DTX > 31.25 mSec, it is determined that the elevator arrives and the landing door is opened, and the message B is announced to the elevator landing 1. Note that after both the magnetic sensors A and B are turned on, the operation of turning off the magnetic sensor A or B and then turning off the magnetic sensor B or A is regarded as starting or passing from the floor.

Next, the deceleration check operation by the UP / DOWN common deceleration detection sensor of the elevator hall door pull-in prevention device will be described with reference to FIG.
