A cutting apparatus includes a blade configured to cut a sheet that is conveyed along a sheet conveyance path, a scrap path through which scrap generated when the sheet is cut by the blade passes, a guide member configured to guide the sheet conveyed, and a blowing unit configured to blow air such that the air crosses the sheet conveyance path from a side opposite the scrap path with the sheet conveyance path therebetween, wherein the blowing unit blows air such that the air flows along the guide member positioned at a second position at which the scrap is allowed to enter the scrap path.

A drying device includes: a supporting section that supports a medium on which printing was performed; a conveying section that conveys, along a conveying region, the medium supported by the supporting section; a heat generating section configured to heat, over a width direction, the medium supported by the supporting section; a fix-supporting section configured to support the heat generating section fixing the heat generating section; and free-supporting section configured to support the heat generating section so that the heat generating section can expand and contract, wherein the fix-supporting section is located in a first lateral region that is a region outside the conveying region in the width direction, and the free-supporting section is located in a second lateral region that is a region outside the conveying region in the width direction and different from the first lateral region.

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 sheet feeding apparatus includes a sheet supporting portion, a sheet feeding portion configured to feed a sheet supported on the sheet supporting portion in a sheet feeding direction, an air blow unit including an air blower, an opening portion, a duct configured to form a flow path through which air flows, an adjustment portion configured to vary an opening dimension, the air blow unit being configured to separate a plurality of sheets, including an uppermost sheet, a drive source configured to drive the adjustment portion, and a control unit configured to execute a first mode in which the drive source is controlled such that the opening dimension is set to a first dimension, and a second mode in which the drive source is controlled such that the opening dimension is set to a second dimension that is smaller than the first dimension.

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 postprocessing device includes a sheet conveying passage, a sheet tray, an inlet guide, a processing device, and a blowing device. Though the sheet conveying passage, a sheet on which an image has been formed is conveyed. The sheet tray is arranged downstream of the sheet conveying passage and has sheets stacked on it. The inlet guide is arranged at the downstream end of the sheet conveying passage and guides a sheet to the sheet tray. The processing device performs predetermined processing on a sheet stacked on the sheet tray. The blowing device blows air, from the upstream side in the sheet conveying direction, between the top face of the top-most sheet in the sheets stacked on the sheet tray and the bottom face of the subsequent sheet sent from the inlet guide into the sheet tray.

A sheet feeding device includes: a stacker that stacks sheets of paper; a suction conveyor disposed vertically above the sheets stacked in the stacker for sucking and conveying the sheets; a blower that blows air onto the sheets; and a regulating member disposed on a downstream side of the suction conveyor in a conveyance direction, facing an outlet of the sheets of the suction conveyor and projecting vertically upward, wherein the suction conveyor includes: horizontal portions provided on both ends in a width direction; and a recess provided in an intermediate portion and recessed vertically above the horizontal portions, and a lower limit of a projection height of the regulating member is set so that, when there is a vertical gap between a vertical upper end portion of the regulating member and the horizontal portions, a length of the gap is less than twice a thickness of the sheets.

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.
