1. A sheet transport device comprising:
a transport path along which a sheet is transported in one direction; a sheet butting portion provided at one side of the transport path, against which sheet butting portion a side edge of the sheet on the transport path is butted; a sheet rotating section; and a sheet butting section disposed on a downstream side of the sheet rotating section, wherein, when a short sheet, which has a smaller sheet length than a predetermined sheet length, is transported along the transport path, the sheet rotating section rotates the short sheet such that a leading end thereof is directed to the other side of the transport path, and when a long sheet, which has a larger sheet length than the predetermined sheet length, is transported, the sheet rotating section rotates the long sheet such that an angle of inclination with respect to the one direction is reduced, and wherein the sheet butting section moves the short sheet rotated by the sheet rotating section toward the one side of the transport path to make the side edge of the short sheet butt against the sheet butting portion, while allowing the long sheet to pass therethrough without moving the long sheet toward the one side. |
