<P>PROBLEM TO BE SOLVED: To provide a powder transport system which can transport powder to a desired distance in a clean powdery state remaining powdery state by means of simple composition. <P>SOLUTION: The powder transport system includes an opening section 72a as a feed opening to which powder is fed, an aspirator 51 having a suction path 72 connected with the feed opening concerned to make the lower part of the suction path 72 small diameter section, and an air flow path 60 which delivers air into the small diameter section of the aspirator 51 through the outer periphery of the aspirator 51 to enhance suction force from the feed opening. In the suction path 72 connected with the feed opening, while holes into which air is blown from external are formed over peripheral walls, a cylindrical body 73 is prepared to make the air blown from the holes permeate into hollow section and a delivery section 70 is also prepared to deliver powder from the feed opening to the small diameter section side through the cylindrical body 73. <P>COPYRIGHT: (C)2012,JPO&INPIT |
