Abstract: A medium processing system includes: a pre-processing device; a first delivery device that receives a recording medium from the pre-processing device and that delivers the recording medium; a first post-processing device that receives the recording medium delivered from the first delivery device and that performs post-processing on the recording medium; one second delivery device or multiple second delivery devices that are connected in series with the first delivery device, that receive the recording medium delivered from an upstream side in a transport direction of the recording medium, and that deliver the recording medium; a second post-processing device that receives the recording medium delivered from the one second delivery device or the multiple second delivery devices and that performs post-processing on the recording medium; a first controller that is provided at the first delivery device and that communicates with the first post-processing device, the pre-processing device, and the second delivery

Abstract: A feeding device includes: a loading portion that is disposed on a downstream side of a transporting path in a transporting direction and that loads a transporting target, which is transported through the transporting path, on a loading surface inclined with respect to a horizontal direction; and a feeding unit that feeds the transporting target, which is in contact with the loading surface, obliquely upward along the loading surface.

Abstract: A transporting device includes a carrying-in unit that carries in a sheet-shaped transporting target, a rotation unit that rotates the transporting target, which is carried in by the carrying-in unit, in a view toward a thickness direction, and a discharging unit that discharges the transporting target rotated by the rotation unit.

Abstract: An intermediate transport device includes: a changing unit that changes a direction of a recording medium received from a pre-processing device to at least one of one direction and another direction with respect to a receiving direction in which the recording medium is received, and delivers the recording medium; and a housing that has a delivery port through which the recording medium delivered to the one direction toward one post-processing device passes, and another delivery port through which the recording medium delivered to the other direction toward another post-processing device passes, and that is disposed at a height similar to a height of the delivery port.

Abstract: Provided is a post-processing device including a transport unit that transports a recording material which is sequentially transported from an upstream side toward a post-processing unit that performs post-processing on the recording material, a standby unit that is connected to the transport unit, and allows a recording material which is backhauled by a transport section reversible from the transport unit to temporarily standby, a transport member that transport the recording material which stands by in the standby unit and the recording material which is transported in the transport unit to the post-processing unit with the recording materials stacked, and an elastic member that is arranged on an upstream side of a connection position of the transport unit where the standby unit is connected, guides the recording material sequentially transported from the upstream side to the post-processing unit, and guides the backhauled recording material to the standby unit.

Abstract: A sheet folding apparatus has a sheet folding unit which can apply at least letter folding on a sheet, and a folding mode selecting device which can selectively cause the sheet folding unit to operate in a letter folding mode. The apparatus further has a control device which controls the sheet folding unit in accordance with the folding mode selected by the folding mode selecting device. A sheet processing apparatus using the sheet folding apparatus, and an image forming apparatus connectable to the sheet folding apparatus are also disclosed.
