I try to stop. For this reason, the abnormality of the operation of the drive operation mechanism 13 is not known until the operation of the escalator stops, and the operation abnormality of the drive operation mechanism 13 cannot be artificially confirmed from outside the step 8B. Therefore, when the safety device itself fails, the driving operation mechanism 1
The operation of the escalator is not stopped even in the abnormal operation state of 3, causing a danger. Also, even if the escalator operation stops abnormally,
It is not possible to immediately determine whether the cause is an operation abnormality of the drive operation mechanism 13 or an abnormality of another safety device, which is inconvenient for maintenance such as taking time for repair work or the like.

持する。The operation of the escalator device having the above-described structure will be described. First, when the wheelchairs K are put on from the normal operation of the escalator, operation commands such as an operation mode changeover switch (not shown) and the like are used to raise and lower the upper and lower floors 40, 41.
Drive racks 40a, 41aa are raised to a predetermined height. In this state, for example, when the escalator goes up, when the first and second special steps 8A, 8B equipped with the wheelchairs K start traveling on the lower horizontal road portion 5a of the forward path 5, the lower-floor elevating mechanism 40 The input forward / reverse pinion 37 of the drive operation mechanism 13A meshes and engages with the drive rack 40a, and the drive rack 40a is driven forward. The drive shaft 34, the drive gear 35, the intermediate gear 36, and the left and right gears 32a and 32b are interlocked. To move the left and right forks 30 backward through the rack 31 to support the movable tread plate 12 of the first special step 8A from below.

While being supported by the step body 11. In the middle of the upper floor horizontal road section 5c, the drive rack 41a of the upper floor elevation mechanism 41 is connected to the-input forward / reverse pinions 37 of the drive operation mechanism 13A of the second special step 8B on the other side. And the forward and reverse rotation pinion 37 is driven to rotate in the reverse direction. The driving shaft 34, the driving gear 35, the intermediate gear 36, and the left and right gears 32a, 32b
This causes the left and right forks 30 to move forward through the rack 31 to retreat into and return to the second special step 8B, and to be separated from the movable step plate 12 of the first special step 8A. Since then
The drive racks 40a, 41a of the elevating mechanisms 40, 41 descend and retreat, and the forward / reverse rotation pinion 30 does not engage with them.
While the drive operation mechanism 13A remains restored, the steps 8A, 8B
Travels in the same manner as a normal step 8.
