To reduce the cost of a configuration that moves an ejection member in a medium width direction and ejects a medium by shifting.

A paper sheet transportation device includes a first ejection member (Rh) that ejects the medium to a first ejection part and is supported movably in the medium width direction which is vertically in the ejecting direction of the medium, a medium width direction moving mechanism (101) having a first drive transmission member (104) that moves in the medium width direction by transmitting the drive of a drive source (102) connecting to the first ejection member (Rh), a second ejection member (Rh2) that ejects the medium to a second ejection part and is supported movably in the medium width direction, and a second drive transmission member (114) having a connecting part (121) connecting to the first drive transmission member (104) and moving the second ejection member (Rh2) in the medium width direction by transmitting the drive of the drive source (102) connecting to the second ejection member (Rh2).
