To provide a bundle carrying device capable of correcting the curving of bound portions of a bundle when carried, and to provide a paper sheet treatment device equipped therewith.

The driving force of a driving motor 705 is transmitted to a roller 713 via the gear of a roller 702. The driving force of the roller 713 drives a roller 712. As a result, a roller 701 is rotated counterclockwise and the roller 712 is rotated clockwise. The roller 701 and the roller 712 are arranged opposing each other in the state that a minimum gap G to pass the bundle PA therethrough is secured by a stopper 708. A rocking base 710 and a conveyor base 700 are connected to each other via a spring 709, and the rocking base 710 is pulled around the rotational axis of the roller 713 to the side of the conveyor base 700 with predetermined spring force. This construction holds the bundle PA carried between the roller 701 and the roller 712, applies the spring force of the spring 709 thereto, and corrects the curving of the bundle PA with the spring force.
