Abstract:
1. A sheet transport device comprising: a registration section configured to cause a leading edge of a sheet to come into contact with the registration section, thereby stop the sheet, and then feed the sheet again at a predetermined timing; a first sheet transport path configured to feed the sheet from one of two transport directions substantially perpendicular to the sheet transport direction of the registration section; a second sheet transport path configured to feed the sheet from the other of the two transport directions substantially perpendicular to the sheet transport direction; a confluence transport path configured to merge the first sheet transport path and the second sheet transport path on an upstream side of the registration section in the sheet transport direction; and a first guide member located so as to form the confluence transport path such that a space in the confluence transport path becomes smaller from the upstream side toward a downstream side in the sheet transport direction and rotatable about a rotation center on a side of the registration section to the downstream side of the first guide member in the sheet transport direction, and the first guide member rotates toward the first sheet transport path when the sheet is fed from the first sheet transport path to the confluence transport path, and rotates toward the second sheet transport path when the sheet is fed from the second sheet transport path to the confluence transport path.
