ABSTRACT:
A manufacturing apparatus has a clean air supply means provided integrally with a part thereof for supplying clean air toward at least an area in which a workpiece exists, and an air discharge means disposed so as to face the clean air supply means across the workpiece and adapted to discharge the air to the outside of the apparatus. It is therefore possible for clean air to be constantly supplied to the workpiece area under positive pressure. Thus, there is no risk of dust generated not only inside but also outside the apparatus being moved to the vicinity of the workpiece. Accordingly, it is possible to prevent adhesion of dust to the surface of the workpiece by the apparatus alone and also possible to install the apparatus as desired.
