A sheet conveying apparatus includes: a first conveying portion in which a band-shaped sheet including a first surface and a second surface is conveyed with the first surface facing downward; a turning portion located downstream of the first conveying portion and flips the sheet with the first surface facing inward; and a second conveying portion located downstream of the turning portion. The turning portion includes a convex curve along which the sheet is flipped. The convex curve includes a first and a second air ejection portions. The first air ejection portion is located in an upstream end region and ejects air toward the first surface of the sheet. The second air ejection portion is located downstream of the upstream end region and ejects air toward the first surface. The first air ejection portion ejects air to generate flotation larger than that of the second air ejection portion.

A separation/collection device is provided in a paper sheet conveyance device for generating an airstream in a conveyance duct and for conveying a paper sheet inserted into the conveyance duct by being pushed from behind by a conveyance subsidiary body moving in the conveyance duct by receiving the airstream. The separation/collection device separates and collects the conveyance subsidiary body and the paper sheet at an ending portion of a conveyance path. The separation/collection device includes a separation unit that passes the paper sheet pushed and conveyed by the conveyance subsidiary body, in a downstream direction, and that stops the conveyance subsidiary body by contacting the conveyance subsidiary body with the separation unit, a tubular path part that receives the paper sheet output from the separation unit, and a rib provided on an inner wall of the path part.

A post processing apparatus includes a post processing unit that performs a post process on a sheet of paper, a duct, and a blower that blows an airflow to the duct. The post processing apparatus has a transport path through which the sheet is transported toward the post processing unit. The duct is provided in a width direction of the transport path. The duct has a slit formed in a sheet width direction, and the airflow having been blown by the blower is blown through the slit toward the sheet transported to the post processing apparatus.

A paper sheet conveyance device for generating an airstream in a conveyance duct and for conveying a paper sheet inserted into the conveyance duct by being pushed from behind by a conveyance subsidiary body moving in the conveyance duct by receiving the airstream. The paper sheet conveyance device includes an air volume adjustment unit that adjusts a strength of the airstream according to a position of the conveyance subsidiary body moving in the conveyance path.

A sheet conveyance device transports a sheet to a predetermined processing unit, and includes a conveyance belt, a ventilation unit, and a suction unit. The conveyance belt has a first surface and a second surface, and is arranged to be opposed to the processing unit to transport the sheet on the first surface in a predetermined conveyance direction. On an upstream side of the processing unit in the conveyance direction, the ventilation unit blows out wind toward the sheet to adhere the sheet to the first surface of the conveyance belt. The suction unit is arranged to be opposed to the processing unit with the conveyance belt interposed therebetween to generate a negative pressure between the sheet adhered to the first surface by the ventilation unit and the conveyance belt, thereby bringing the sheet into close contact with the first surface of the conveyance belt.

A conveyance apparatus includes a conveyance device including a sheet-bearing member having a curved sheet-bearing surface, the conveyance device conveying a sheet by bearing the sheet with the curved sheet-bearing surface of the sheet-bearing member, and a blower to blow air onto the sheet. The carved sheet-bearing surface of the sheet-bearing member is formed by a plurality of wires defining gaps through which the blower blows air.

A medium discharge unit that discharges a medium subjected to recording by a recording unit, a placement unit at which the medium discharged by the medium discharge unit is placed, the placement unit being inclined with a downstream side in a discharge direction in which the medium is discharged being positioned, in a vertical direction, above an upstream side in the discharge direction, an air blowing unit that blows air from above toward the medium discharged from the medium discharge unit, and a control unit that controls the air blowing unit are included. The control unit can attenuate air blowing by the air blowing unit, based on information of an interval between a preceding medium and a following medium that are to be discharged from a discharge position of the medium discharge unit to the placement unit, when the preceding medium is discharged from the discharge position.

A paper sheet conveyance device for conveying a paper sheet by an airstream generated in a tubular conveyance path. The paper sheet conveyance device includes a frame member that supports the conveyance path and are provided along an installation route of the conveyance path, pedestal units attached to the frame member and that slide along a longitudinal direction of the frame member, and a plurality of paper sheet capturing devices that send out the paper sheet to be conveyed into the conveyance path and are provided in the conveyance path. Each of the paper sheet capturing devices includes a path part that forms a part of the conveyance path, which is formed by joining a plurality of conveyance ducts and the path parts of the paper sheet capturing devices. The pedestal unit is provided for and holds each of the paper sheet capturing devices.

Conveying systems and methods are provided that selectively controls gas-propelling devices to move objects over the conveyer table at different speeds and in different directions. The systems and methods include a conveyer table having of an array of gas-propelling devices that propel gas from a surface of the table. Each of the of gas-propelling devices can have layers arranged in a stack and a through-hole in the stack and the table. The surfaces of each of the layers are exposed in the interior of the through hole and a heating/cooling device selectively heats and/or cools the layers to generate thrust.
