A sheet stacker includes a sheet stacking portion, a guide portion, and an air blower. The sheet stacking portion is configured to stack a sheet bundle. The guide portion is configured to receive a leading end of a sheet conveyed toward the sheet stacking portion and guide the sheet downstream in a sheet conveyance direction in which the sheet is conveyed. The air blower is disposed above the sheet stacking portion and configured to blow air toward the sheet on a downstream side, in the sheet conveyance direction, from a position at which the guide portion receives the leading end of the sheet.

When using a flipping wheel to flip sheets of weak or long media, there is a risk that these sheets collapse upon themselves. To reduce this risk, a method of stacking sheets includes flipping a sheet while holding its leading edge and bringing the leading edge down towards a stack support; bringing a trailing portion of the sheet into contact with a guide member positioned over the stack support; forming an overpressure in an inner volume of the bent sheet during flipping, while its trailing portion is in contact with the guide member; and maintaining the overpressure and contact while a trailing edge of the sheet travels along the guide member.

The apparatus includes a first ejection unit, a processing tray, a blower unit, a control unit, and a post-processing unit. The first ejection unit ejects a medium recorded by ejection of a liquid. On the processing tray, the medium ejected by the first ejection unit is stacked. The blower unit blows air to the medium stacked on the processing tray. The control unit controls the blower unit. The post-processing unit post-processes the medium stacked on the processing tray. Based on processing information about processing performed on the medium, the control unit changes a blowing amount at which the blower unit blows air.

A sheet stacking device include a guide unit and a blower. The guide unit receives a downstream end of a sheet in a sheet conveyance direction and guides the sheet downstream in the sheet conveyance direction. The blower blows air toward the sheet guided by the guide unit. A region of the blower from which the air is blown is changeable in response to a size of the sheet.

An image forming apparatus (1) includes a discharge port (25), a sheet stacking plate (41), a pair of cursors (43), a cursor driver (95), a pair of blowers (83) and a controller (37). Through the discharge port (25), a sheet formed an image is discharged. On the sheet stacking plate (41), the sheet discharged through the discharge port (25) is stacked. The pair of cursors (43) is supported on the sheet stacking plate (41) in a slidable manner in width directions perpendicular to a discharge direction of the sheet and comes into contact with both side edges of the sheet. The cursor driver (95) drives the pair of cursors (43). The pair of blowers (83) is provided in the pair of cursors (43) so as to blow air to both corners on an upstream side in the discharge direction of the sheet which is discharged through the discharge port (25), from above. The controller (37) controls the cursor driver (95) and the pair of blowers (83).

A medium feeding device includes a container member that accommodates sheet media, a discharging member disposed further than the media accommodated in the container member in a discharging direction in which the media are discharged, a hand-over member disposed above the container member at a position closer to the discharging member, a floating device disposed on a side of the media accommodated in the container member, and an auxiliary suction member disposed above the container member on a side of the hand-over member opposite to a side closer to the discharging member in the discharging direction in which the media are discharged. The auxiliary suction member is disposed closer to the hand-over member than to an end portion of the media accommodated in the container member opposite to an end portion of the media located closer to the discharging member.

A banknote transport system 10 includes: an air blowing tube 100 that forms an air flow path 101; a moving body 200 that travels inside the air blowing tube while receiving an air flow within the air blowing tube; a transport path 401 (a transport tube 400) having at least a portion arranged along the air blowing tube to be adjacent to the air blowing tube; and a transport body 500 configured to be able to retain a banknote and traveling inside the transport path. The moving body includes a moving body magnet 213, and the transport body includes a transport body magnet 523. The banknote transport system moves the transport body in conjunction with movement of the moving body receiving the air flow due to attraction and/or repulsion based on a magnetic force applied between the moving body magnet and the transport body magnet.

A conveyance device includes a support having a support face configured to support a conveyed object and a fluid introduction device disposed outside the support. The fluid introduction device is configured to introduce a fluid between the support face of the support and the conveyed object, to form a fluid layer for floating the conveyed object. The conveyance device further includes a conveyor configured to convey the conveyed object being floating from the support via the fluid layer.

The apparatus includes a first ejection unit, a processing tray, a blower unit, a control unit, and a post-processing unit. The first ejection unit ejects a medium recorded by ejection of a liquid. On the processing tray, the medium ejected by the first ejection unit is stacked. The blower unit blows air to the medium stacked on the processing tray. The control unit controls the blower unit. The post-processing unit post-processes the medium stacked on the processing tray. Based on processing information about processing performed on the medium, the control unit changes a blowing amount at which the blower unit blows air.

A sheet discharge apparatus includes a discharge unit configured to discharge a sheet in a discharge direction, a stacking surface configured to stack the sheet discharged by the discharge unit, and a wall including a plurality of hole portions and an abutting part, wherein the plurality of hole portions includes a first hole portion disposed across an extension line along the stacking surface when viewed in a width direction, the first hole portion including a first edge portion and a second edge portion, the first edge portion being positioned on a side of the stacking surface, and wherein, in the vertical direction, an upper end of the first edge portion of the first hole portion is positioned above the extension line, and a lower end of the first edge portion of the first hole portion is positioned below the extension line.
