It is a device that adjusts the operation of the escalator, sensing people boarding and getting off.
Previously, it was operated when people pass the pillar placed between the entrance and exit.
In this case it detected people passing rather than not near it, so it has a disadvantage that the operation is possible only when sensor pillar must be in some degree away from the escalator before people approaching.
Therefore, it is possible to eliminate the space that had to be reserved for existing pole installation,
and there is a advantage of being accessible to side.
