PURPOSE: To appropriately treat an article where thickness changes for each part of a printed-circuit board or the like by a fluid-treating device such as an air knife. CONSTITUTION: A device is provided with a first conveyor means 30 that is engaged to the lower surface of an article 81, a second conveyor means 50 that is engaged to the upper surface of the article, and a fluid-treating means for performing the fluid treatment of the article in a fluid-treating device. Then, the fluid-treating means is provided with a means for unloading treatment fluid through a delivery port 90 of a fluid delivery pipe, a following means for allowing the fluid delivery pipe to follow one conveyor means 50 that is adapted to a different thickness in vertical direction at each portion of the article and for adapting the delivery port of the fluid delivery pipe essentially to different thickness in a vertical direction at each part of the article, and a means for automatically rotating the fluid delivery pipe by the amount corresponding to the different thickness in a vertical direction at each part of the article.
