PROBLEM TO BE SOLVED: To provide a follow-up carriage capable of improving user-friendliness by suppressing unnecessary follow-up operation.SOLUTION: A movable carriage 2 including leading object detection means 23 for outputting an azimuth and distance of a leading person and an infrared sensor for detecting infrared light by an external unit 3 has controls switched according to whether an infrared sensor is in a detection state or is in a non-detection state. In the detection state, follow-up movement control is performed so that the azimuth and distance of the leading person are predetermined values. The follow-up movement control is stopped in the non-detection and is resumed when the infrared sensor is returned to the detection state. |
