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 post-processing device includes an output unit that outputs a medium; a stacking unit on which the medium that is output is stacked; and a blow-out unit that is disposed below the output unit and that blows gas toward the medium that is output, wherein a direction in which the gas is blown differs in accordance with a type of the medium.

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 sheet supplying device includes: an air blow opening configured to blow air to a side portion of an uppermost part of stacked sheets; and a flow adjuster extending from above the air blow opening over an edge of a top sheet of the stacked sheets and configured to cause an air flow blown from the air blow opening to travel along an upper surface of the top sheet of the stacked sheets.

A post-processing device includes a discharge port through which a sheet is discharged, an intermediate tray, a discharge tray and an air sending part. The air sending part includes an upper air sending member, an upper switching member, a lower air sending member, a lower switching member and a controller. The upper air sending member generates a downward air flow from above the discharge port. The upper switching member is distributable the air flow generated by the upper air sending member to above the intermediate tray and to above the discharge tray. The lower air sending member generates an upward air flow from below the discharge port. The lower switching member is distributable the air flow generated by the lower air sending member to below the intermediate tray and to above the discharge tray. The controller controls the upper switching member and the lower switching member.

A feeding apparatus comprises a blower unit that is able to perform a first air blowing operation on sheets which are stacked on a stacking unit, and a second air blowing operation in which the volume of air blowing is smaller than volume of air blowing in the first air blowing operation; a feeding unit, brought into contact with the sheets stacked on the stacking unit and located on a feeding position to which feeding is performed while pressing the sheets from above, for feeding the sheets on which the first air blowing operation has been performed; and a control unit for controlling the blower unit to perform the first air blowing operation until a start of feeding by the feeding unit so as to separate the sheets stacked on the stacking unit.

A sheet feed device includes: a conveyor configured to convey a top sheet of sheets floated from a sheet stack; a blower configured to blow air in an obliquely upward direction from a position lower than the conveyor toward the sheet stack; and a direction converter configured to convert a direction of the air blown by the blower to a direction which is downward more than a direction of the air at a position where the air is blown from the blower and let the air flow in between the top sheet and a second sheet subsequent to the top sheet of the sheets floated from the sheet stack.
