A sheet processing device can prevent a folded sheet bundle from being opened upon accumulation to prevent a reduction in accumulation amount thereof. The sheet processing device includes a pair of pressing rollers pressing a folding loop of a folded sheet bundle in a thickness direction, a support unit mounted to a device frame and supporting a plurality of rows of the pressing roller pairs such that intervals therebetween in the row direction are reduced stepwise, and a gripper member that makes the folding loop of the folded sheet bundle pass through the support unit in a direction that the intervals of the plurality of rows of pressing roller pairs in the row direction are reduced stepwise. The folded sheet bundle passes through the support unit by the gripper member to cause the folding loop to be sequentially pressed by the plurality of rows of pressing roller pairs.

A rotary banknote conveying device applicable to a banknote inlet/outlet of an automatic teller machine includes a banknote clamping mechanism configured to convey banknotes from the banknote inlet/outlet to an inlet of a banknote conveying passage inside the automatic teller machine; a transmission mechanism including a drive motor, a belt and a pair of pulleys; a first rotary driving mechanism including a first rotary motor and a first transmission gear and configured to drive the banknote clamping mechanism to rotate by a first angle at the banknote inlet/outlet; a second rotary driving mechanism including a second rotary motor and a second transmission gear and configured to drive the banknote clamping mechanism to rotate by a second angle at the inlet of the banknote conveying passage; and a central control mechanism including a control unit, a first position sensor, and a second position sensor.

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 three side trimmer has a trimming unit 1, an accumulating unit 3, a discharge unit 2 and a conveying mechanism 4 conveying trimmed booklets BK to the accumulating unit. The accumulating unit has a shelf 5 movable in a vertical direction, and a drive roller conveyor 7 on the shelf. The accumulating unit, in a mode, delivers the trimmed booklets to the discharge unit at every accumulation of a predetermined number of the trimmed booklets and, in another mode, accumulates the trimmed booklets without delivering.

Example implementations relate to print media stacks. In some examples, a device may include a sheet channel to guide a sheet of print media within the sheet channel above and separated in a vertical direction from a stack of printed media when the sheet of print media exits a print path of a printer. The device may include a plurality of clamps to control alignment of the sheet of print media on the stack of printed media when the sheet channel moves outboard from the sheet of print media to allow the sheet of print media to fall onto the stack of printed media, wherein the plurality of clamps sequentially pin the sheet of print media to the stack of printed media from a middle portion of the sheet of print media outward.

A sheet stacking apparatus includes a sheet alignment mechanism configured for aligning a sheet in a predetermined reference position; a gripper arrangement configured to grip the aligned sheet at at least two spaced-apart points of the sheet and to release the sheet on a stack; and a holder configured to hold the sheet in position on the stack while the gripper arrangement releases the sheet. The gripper arrangement is movable along a predetermined trajectory for moving the sheet from the reference position to a stacking position.
