ABSTRACT:
A switchback transport mechanism includes a first transport section, a second transport section, a third transport section, and a transport control section. The first transport section applies propelling force to a sheet in the guiding path. The second transport section applies propelling force to a sheet in the ejecting path. The third transport section has a first transport member and a second transport member placed so as to be attached to and detached from each other. The third transport section selectively applies propelling forces in a frontward direction and a backward direction to a sheet in the switchback transport path through the first and second transport members. The transport control section controls operations of the first, second, and third transport sections. The transport control section detaches the first and second transport members from each other in a time period when no sheet is being transported by the third transport section.
