PROBLEM TO BE SOLVED: To provide a conveyance device capable of good conveyance of paper sheet. SOLUTION: In a paper sheet conveyance device, an air delivery tube 22 is connected with a twisted tube part 68, which has ribs connected to ribs 40 of the air delivery tube 22 and is twisted by a predetermined angle with respect to the air delivery tube 22, and a bending device 30 feeds paper sheets with deformed part 32b in an air delivery tube 22 to convey the paper sheets by wind pressure acting on the deformed part 32b. If it is detected that paper sheets are put in a plurality of air delivery tubes 22, a control part 90 opens an on-off valve 80 of one air delivery tube 22 out of the plurality of the air delivery tubes 22 and closes on-off valves 80 of other air delivery tubes 22 to feed the paper sheets in one air delivery tube 22. After the paper sheets are collected by a collection device 34, the control part 90 closes the on-off valve 80 of one air delivery pipe 22, and controls a drive part 85 to sequentially open the on-off valve 80 of another air delivery pipe 22.
