A switchback mechanism (2a) for reversing a mail item (M) conveying direction has a switchback roller (14, 16) which holds the mail item (M) in a nip (N) and rotates in both forward and backward directions. When there is a remaining mail item deviated from the nip (N) of the switchback roller and remaining in the switchback unit (12), a pressure roller (45) is pressed to an output roller (41) always rotating in the direction of R1, the remaining mail item is held and fed out to the nip (N). At this time, a control unit takes out the remaining mail item at timing not to interfere with other mail items.
