A sheet discharge port is provided with a guide piece extending obliquely downward in a discharge direction from an upper edge of the sheet discharge port to oppose an outlet port. The guide piece blocks flow of cooling air, which has been blown out from the outlet port, into the sheet discharge port and also abuts the sheet discharged from the sheet discharge port to guide the sheet obliquely downward in the discharge direction.

A delivery system is used for delivering printed sheets which can be fed in a region of an inlet side of a delivery device. The delivery device includes at least one first discharge station and one second discharge station which is mounted downstream of the first discharge station, which is upstream in the transport path. The delivery stations are associated respectively with a format or transport-relevant device which can be controlled by a drive including a control element for adapting or correcting the guiding and delivery of the sheets in the relevant discharge station. At a delivery device level upstream of a lateral inlet in a stacking space of the upstream second discharge station, at least one operator interface, with at least one actuating device is provided. The at least one actuating device can be permanently connected to a signal or can be activated by an additional actuating device, with the control element of the at least one format- or transport-relevant device of the first discharge station and which allows or which can allow, during actuation, the control element of the system of the first discharge station which can vary with regard to the format- or transport-relevant size format, to be controlled.

A sheet stacking system includes a conveyor for carrying sheets from a conveyor intake end to a conveyor discharge end and a hopper at the discharge end for receiving the sheets and guiding them as they fall in a cascade path onto a platform. The hopper has a backstop facing the discharge end of the conveyor and a first accumulator that includes a carrier and a support extending from the carrier through the backstop. The support is configured to rotate from a retracted position to an extended position relative to the backstop, and the carrier is movable linearly and vertically relative to the backstop with the support in the extended position from a raised location with the support outside the cascade path to a lowered location with the support in the cascade path.

An apparatus is disclosed. For example, the apparatus includes a paper feed to feed print media a single sheet at a time, a plurality of rotating discs, wherein each one of the plurality of rotating discs comprises an elastomer ring to secure a leading edge of the single sheet against a registration wall and initiate a flipping process, a plurality of fans to generate an air flow, wherein the air flow levitates a trailing edge of the single sheet during completion of the flipping process, and a movable platform to hold a stack of the print media.

A sheet stacker includes a stacking member, transporting member, guiding member, a plurality of blowers, and controller. A sheet is stacked on the sheet stacker. The transporting member transports a sheet in a sheet-transporting direction towards the stacking member. The guiding member retains an edge portion of the sheet transported by the transporting member in a standby position, followed by moving in the sheet-transporting direction to guide transporting of the sheet. The blowers discharge air flows towards the sheet transported to the stacking member. The air flows are directed towards a top plane of the stacking member. One of the blowers is disposed in a position corresponding to the detaching position. The controller controls motions of the blowers and air volumes from the blowers based on information regarding a length of the transported sheet.

A sheet stacker includes: a loader to which a sheet bundle is to be loaded; a guide to receive a leading end of a sheet conveyed to an area above the loader, and guide the sheet along a guide path above the loader in a conveyance direction; a blower disposed above the guide path of the guide to blow air downward to the sheet; and multiple lines: disposed above the guide path of the guide; and extending in a direction inclined relative to the conveyance direction.

A recording apparatus includes: a mount base having a mount surface on which a sheet discharged through a medium discharge outlet is mounted, the mount surface facing the recording surface of the sheet; a projection rib that is provided in the mount base, is projectable from the mount surface, and extends along a discharge direction of the sheet discharged through the medium discharge outlet, through a center of the sheet in a width direction crossing the discharge direction of the sheet; and a projection mechanism that causes the projection rib to project from the mount surface to a rib height according to a dimension of the sheet in the width direction discharged through the medium discharge outlet.

To stop a variety of sheets and prevent problems generated by colliding sheets, a front stopping device that receives sheets being delivered along a horizontal transport route on a hopper unit and stops the movement in the transport direction includes a plate-shaped buffering member that is brought into direct contact with the front part of a sheet; and supporting members that support the upper end and lower end of the buffering member. The buffering member is formed of a flexible material to absorb the kinetic energy of the sheet by being elastically deformed in a concave surface shape when receiving the front part of the sheet, and the buffering member is supported by being inclined upward or downward by the supporting members such that a restoring force of pushing back the front part of the sheet due to the restoration of the elastic deformation includes a vertical component.
