A sheet processing apparatus includes a roller pair configured to convey a sheet, a sheet bundle conveyer configured to convey a sheet bundle to the roller pair, and circuitry configured to cause the sheet bundle conveyer to contact leading edges of sheets of the sheet bundle to the roller pair and cause the roller pair to rotate in reverse to align the leading edges of the sheets of the sheet bundle.

A sheet processing device includes a first conveyance passage, a first conveyor, a second conveyor, a folder, a second conveyance passage, and circuitry. The circuitry is configured to (1) cause the first conveyor and the second conveyor to convey the sheet nipping the sheet to warp the sheet between the first conveyor and the second conveyor, (2) guide the warped sheet to form a first fold on the sheet by the folder and circulate the sheet to the first conveyance passage, (3) cause the first conveyor and the second conveyor to convey the sheet while nipping the sheet again to warp the sheet between the first conveyor and the second conveyor, (4) guide the warped sheet to form a second fold on the sheet by the folder, and (5) cause the second conveyor to convey the sheet with the first fold and the second fold.

A sheet processing apparatus for processing sheets includes: a stack tray on which a sheet is stacked; a discharge roller pair composed of first and second rollers and configured to discharge a sheet onto the stack tray, the second roller being configured to be movable between a pressure contact position to contact with the first roller and a retracting position to separate from the first roller; and a pressure contact/separation mechanism for moving the second roller from the retracting position to the pressure contact position. The pressure contact/separation mechanism changes the timing at which the second roller reaches the pressure contact position according to the type of a sheet to be discharged.

The invention which solves the relative speed problem between nips in a printing system is disclosed. The invention consists of a swing arm body that rotates about a pivot, an input drive gear, a forward swing arm gear, two reverse swing arm gears, a compound duplex drive gear, and a housing.

A conveying direction switching apparatus includes a first switching gate that, at a joint portion of a first conveying path, a second conveying path, and a third conveying path, switches between a first conveyance route connecting the first conveying path and the second conveying path and a second conveyance route connecting the first conveying path and the third conveying path, a second switching gate that switches between the first conveyance route and a third conveyance route connecting the second conveying path and the third conveying path, and a free gate that is arranged on a same shaft as the first switching gate such that a second conveyance route side is opened by an elastic body at a joint portion of the second conveyance route and the third conveyance route.

The disclosure relates to a banknote handling machine comprising: a banknote transport arrangement configured to transport banknotes along transport paths within the machine, wherein the banknote transport arrangement comprises a diverter assembly comprising: a diverter rotatably attached to a structure of the machine, and an electric motor configured to transfer kinetic energy to the diverter so as to rotate the diverter between a first position and a second position, wherein the diverter, when in the first position, is configured to control banknotes to be transported along a first transport path, and wherein the diverter, when in the second position, is configured to control banknotes to be transported along a second transport path.

There is provided a medium conveying device which includes a conveyance belt passed around a first roller and a second roller and configured to support and convey a medium on a supporting surface, and in which a controlling unit is able to execute first control to determine whether a first skewing direction and a second skewing direction are the same, the first skewing direction indicating whether, when the first roller and the second roller are caused to rotate in the first rotational direction, the conveyance belt moves toward one side or the other side in a width direction intersecting a moving direction of the conveyance belt, and the second skewing direction indicating whether, when the first roller and the second roller are caused to rotate in the second rotational direction, the conveyance belt moves toward the one side or the other side in the width direction.

A medium transporting apparatus including a transport belt that transports a medium while suctioning the medium against a transport surface, a first tray on which the medium transported with the transport belt is mounted, and a transport roller configured to move between a transporting position that nips the medium with the transport belt, and a retracted position that is a position distanced away from the transport belt with respect to the transporting position, in which the transport roller is positioned at the retracted position when a single medium is transported with the transport belt and is positioned at the transporting position when a plurality of mediums in a superposed state are transported with the transport belt.

A sheet conveyance device includes: a first conveyance path configured to allow a sheet to be conveyed along the first conveyance path; a second conveyance path that extends upward from a branch position in the first conveyance path; a third conveyance path that extends downward from the branch position; a first conveyance roller disposed in the second conveyance path and configured to rotate normally and reversely to convey the sheet; a first drive motor disposed below the branch position; and a first belt disposed in a drive transmission path from the first drive motor to the first conveyance roller and configured to transmit a driving force from the first drive motor to the first conveyance roller.

In order to enable a sheet to be properly guided to a nip portion in performing folding processing, a sheet processing apparatus for performing folding processing on a sheet is provided with a rotating body pair which nips the sheet by a nip portion to rotate, and thereby draws the sheet to perform folding processing, a folding blade that pushes the sheet to the nip portion of the rotating body pair, and a blade guide member including a guide portion for pushing the sheet to the nip portion when the folding blade pushes the sheet to the nip portion, where the folding blade and blade guide member are relatively shifted so that a distance from a push front edge portion to the guide portion when the folding blade pushes the sheet to the nip portion is longer than a distance from the front edge portion to the guide portion.
