Abstract: A conveyance unit conveys the sheet to an accumulation portion. A half-folding processing unit includes a folding roller pair and performs a half-folding process on the sheet bundle. A conveyance roller pair conveys the sheet bundle. A square back processing unit performs a square back process on the sheet bundle and includes a pair of clamp portions. A length of a conveyance path from the folding roller pair to the pair of clamp portions is larger than a half of a length of a long side of a sheet of a maximum size. In a state in which conveyance by the conveyance roller pair of a first sheet bundle to be subjected to the square back process is stopped, the conveyance unit conveys at least one sheet included in a second sheet bundle subsequent to the first sheet bundle toward the accumulation portion.

Abstract: A square back processing unit performs a square back process on the sheet bundle and includes a pair of clamp portions. The sheet bundle subjected to the square back process by the square back processing unit is discharged to a sheet bundle discharge unit. A cover unit is provided downstream of the square back processing unit in the conveyance direction such that a child access probe according to a safety standard IEC 62368-1 does not reach the pair of clamp portions in a case where the child access probe is inserted from an outside of the sheet processing apparatus.

Abstract: A recording device includes a recording unit configured to discharge liquid onto a medium to perform recording, a transport unit configured to transport the medium at a position facing the recording unit, a transport unit downstream roller pair located downstream the transport unit in a medium transport path and configured to transport the medium, a restricting roller being a roller configured to restrict movement of a medium back end region upstream the transport unit downstream roller pair in the medium transport path toward the recording unit side, and including a plurality of teeth along an outer periphery thereof, and a guide member being a member configured to support the restricting roller, and guiding the medium.

Abstract: A recording device includes a recording head that performs recording on a medium, a transport belt that sucks and transports the medium at a position facing the recording head, a charging unit that forms a charging sucking area on the transport belt, in which the medium is sucked by charging, by applying a voltage to the transport belt, and a control section that controls the charging unit. A belt downstream roller pair that transports the medium is provided downstream of the transport belt in a medium transport direction. After a downstream end of the medium is nipped by the belt downstream roller pair, the control section controls the charging unit so that an upstream area downstream of an upstream end of the medium, which is an area including the upstream end of the medium, does not come into contact with the charging sucking area of the transport belt.
