ABSTRACT:
An automatic controlling apparatus of a boarding bridge to match a position of the boarding bridge with an airplane, includes: a light irradiator, an optical sensor, and an actuator. The light irradiator irradiates a light to the airplane. The optical sensor can detect a reflection wave of the light reflected from the airplane. The actuator moves the boarding bridge such that a position of the boarding bridge is matched with the airplane, based on a detection result of the reflection wave detected by the optical sensor.
