ABSTRACT:
The present invention provides a transporting apparatus provided with a sensor for detecting information relating to a relative position in the vertical direction between an article to be transported and a holding portion for holding the article, and a controller that is linked to this sensor through signals, wherein the controller raises the holding portion by a set raising amount when the sensor detects that the holding portion is below a target lowering position. Thus, it is possible to provide a transporting apparatus with which the position of the holding portion can be automatically moved to a suitable position even if the holding portion is lowered too far with respect to the article.
