In some examples, a gimbaled monoclamp can include a housing including a first opening, a second opening, and a pivot point, a clamp disposed at least partially in the housing and including a first pad and a second pad to extend through the first opening and the second opening, respectively, and a pin extending through an opening in the clamp into the pivot point to couple the clamp to the housing in a gimbaled manner.

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.

Example printer finishing apparatus are described herein. An example printer disclosed herein includes an alignment guide, a track to align a sheet relative to the alignment guide, a clamp to move between a raised position and a lowered position relative to the sheet, and a force applicator coupled to the clamp. The force applicator is to cause the sheet to engage the alignment guide when the clamp is in the lowered position.

During flipping sheets may fold upon themselves under the influence of gravity. To prevent a sheet stacker is provided with a support device for supporting an inner surface of the sheet during flipping, the support device comprising a plurality of flexible fingers elements of different length, each configured to support a different inner area of the sheet during its flipping motion.

A sheet stacking apparatus includes a pair of sheet alignment mechanisms disposed to face each other in a direction of conveyance of a sheet or in a direction orthogonal to the direction of conveyance. Each one of the pair of sheet alignment mechanisms includes an aligning member, an elastic member, a driver, and a driving source. The aligning member reciprocates with reference to the sheet. The elastic member extends due to reaction force generated in response to pressing force applied to an edge of the sheet by the aligning member when a size of the sheet is larger than a prescribed size. The driver is coupled to the aligning member via the elastic member. The driving source transfers a driving force to the driver.
