    Abstract: A sheet post-processor of this disclosure is provided with a punching device and a registration roller. The punching device is capable of forming punch holes along a first side end edge of a sheet parallel to a sheet width direction orthogonal to a sheet conveyance direction and a second side end edge of the sheet parallel to the sheet conveyance direction. The registration roller is disposed downstream of the punching device in the sheet conveyance direction. The punching device includes a punch unit that forms punch holes through a sheet and an edge sensor that detects the second side end edge of a sheet. In a case of forming punch holes along the second side end edge of a sheet, without skewing of the sheet being corrected by the registration roller, the edge sensor detects the second side end edge, while the punch unit forms punch holes through the sheet.

    Abstract: A decurler device corrects a curl of a sheet. The decurler device includes a first roller, a second roller and a support unit. The first roller rotates about a first rotational shaft as an axial center. Further, the first roller is elastically deformable. The second roller rotates about a second rotational shaft in parallel with the first rotational shaft as an axial center. Further, the second roller is pressed by the first roller to elastically deform the first roller, thereby forming a curved nip portion between itself and the first roller. The second roller rotates to convey a sheet. The support unit rotatably supports the first and second rollers. Further, the support unit is rotatable about a third rotational shaft in parallel with the first rotational shaft as an axial center. The support unit rotates when a sheet is conveyed with it nipped by the nip portion.

    Abstract: A sheet stacking device includes a discharge port, an alignment wall, a discharge tray, an alignment belt, and a guide part. The alignment wall extends in an upper-and-lower direction below the discharge port. The discharge tray is provided so as to be capable of moving up and down along the alignment wall. The alignment belt with endless is stretched along the alignment wall in the upper-and-lower direction. The alignment belt has an inner circumferential surface facing the alignment wall and an outer circumferential surface with which an upstream edge of the sheet stacked on the discharge tray comes into contact, and circulates at a same speed as the discharge tray in synchronization with the discharge tray. The guide part is configured to be provided between the alignment wall and the alignment belt. With the guide part, the inner circumferential surface of the alignment belt slides in contact.

    Abstract: In a first punching mode, a control portion displaces a support member from a first-path-side end side to a second-path-side end side, and causes a first punching portion on the first-path-side end side to operate in a state where the support member has reached a first target position. In a second punching mode, the control portion displaces the support member from the second-path-side end side to the first-path-side end side, and causes a second punching portion on the second-path-side end side to operate in a state where the support member has reached a second target position. The first and second target positions are based on positions of the support member at points of time when edges on the first-path-side end side and the second-path-side end side are detected by the first sheet sensor and the second sheet sensor, respectively.

    Abstract: A sheet post-processing device includes a folding portion, a discharge portion, a stacking tray, a shift unit, a pair of alignment members, and a controller. The pair of alignment members include first and second alignment members at one and the other side of sheets stacked on the stacking tray. When a sheet bundle sorted and stacked on the stacking tray includes a folded sheet, executes a second alignment mode in which it performs, for sheets shifted to a first position at one side on the stacking tray, alignment with only the first alignment member and, for sheets shifted to a second position at the other side, alignment with only the second alignment member, or does not perform alignment process.

    Abstract: A sheet binding device includes a first binding unit that performs a first binding process of binding a sheet bundle having a first thickness or less without using a staple, and a second binding unit that performs a second binding process of binding the sheet bundle having a second thickness or less exceeding the first thickness using a staple, the first binding process by the first binding device is preferentially executed when the thickness of the sheet bundle is the first thickness or less, and the second binding process by the second binding unit is executed when the thickness of the sheet bundle exceeds the first thickness and is equal to or less than the second thickness.
