A printer includes a record section, a discharge section, a mount section, a movable rib, a move section, and a control section. The record section records on a sheet by ejecting an ink to the sheet. The discharge section discharges the sheet. The mount section has a mount surface on which the sheet discharged is mounted. A movable rib is configured to protrude from the mount surface and supports the sheet. The dimension of the movable rib in an A-direction is larger than the dimension thereof in a Y-direction. The move section moves the movable rib in a C-direction. The control section controls, based on temperature and humidity information, movement of the movable rib made by the move section.

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.

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.

A sheet stacking device includes a stacker, a detector, a blower, and a moving device. A sheet is stacked on the stacker. The detector detects a stacking amount of the sheet on the stacker. The blower blows air to the sheet stacked on the stacker. The moving device moves the blower with respect to the stacker based on the stacking amount of the sheet detected by the detector.

Provided is a recording device that includes a recording head that ejects a liquid, a discharge unit that discharges a recorded recording medium, a discharge tray that receives a discharged recording medium, a first blowing unit that is disposed above the discharge unit and blows air toward one surface of the recording medium to be discharged to the discharge tray, and a second blowing unit that is disposed between the discharge unit and the discharge tray and blows air toward the other surface of the recording medium to be discharged to the discharge tray, and a control unit that controls the first blowing unit and the second blowing unit, in which deformation of the recording medium to be discharged is suppressed by the wind of the first blowing unit and the second blowing unit and the recording medium is discharged.

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.

The present invention provides a sheet stacking device, a counter-ejector, and a carton former and is provided with: a hopper unit that stacks cardboard boxes; feed rollers that feed a cardboard box to the hopper unit; a first blower device that blows air from above the hopper unit toward the cardboard box fed by the feed rollers; and a second blower device that blows air between the cardboard box stacked in the hopper unit and the cardboard box fed by the feed roller.

A printer includes a record section, a discharge section, a mount section, a movable rib, a move section, and a control section. The record section records on a sheet by ejecting an ink to the sheet. The discharge section discharges the sheet. The mount section has a mount surface on which the sheet discharged is mounted. A movable rib is configured to protrude from the mount surface and supports the sheet. The dimension of the movable rib in an A-direction is larger than the dimension thereof in a Y-direction. The move section moves the movable rib in a C-direction. The control section controls, based on temperature and humidity information, movement of the movable rib made by the move section.
