<P>PROBLEM TO BE SOLVED: To provide a transport tube connection unit capable of connecting a transport tube provided with a rib on an inner wall for transporting a paper sheet by an air flow so that the paper sheet can smoothly pass through a connection part while coping with fine length adjustment. <P>SOLUTION: A plurality of ribs 128 protruding from an adapter 120 have two or more kinds of different terminal end positions, and the rib in a connection body part 100 has a start end position corresponding to the rib 128 at the adapter side. Because the end positions are shifted, even when the connection depth between the adapter 120 and the connection body part 101 is adjusted, there is at least one other rib at the part where any of the rib at the adapter side and the rib at the connection body part side is interrupted, and not all of the ribs are interrupted at the same part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
