A recording apparatus includes a conveying unit, a supporting unit, and a static elimination unit. The conveying unit conveys a recording medium in a first direction to a recording area where recording is performed by a recording unit. The supporting unit supports the recording medium conveyed by the conveying unit and includes an abutment surface that abuts the recording medium when the supporting unit supports the recording medium. The static elimination unit eliminates static from the recording medium in a static elimination portion. The static elimination portion is not provided at a position opposed to the abutment surface and is provided at a position not opposed to the abutment surface in the supporting unit.

An image forming apparatus includes a drawer unit, a sheet inverting unit, a sheet guide plate, and a projection. The drawer unit is drawable from an apparatus body. The sheet inverting unit is disposed in the apparatus body, and pulls a sheet into a lower portion of the drawer unit to invert the sheet. The sheet guide plate is disposed on the sheet inverting unit to face the drawer unit, and includes a recess extending in a pull-out direction of the drawer unit that crosses a direction in which the sheet is transported. The projection protrudes toward the recess from a portion of a lower surface of the drawer unit facing the sheet guide plate near a pull-out start point in the pull-out direction and on a rear of a transport area of the sheet.

Embodiments related to a hold down brush with an improved tine configuration that can be used in a corrugator machine. The hold down brush can include multiple rows of tines made from acetyl, wherein the tines are embedded within a polyurethane base of the brush. The acetyl tines are food-grade and reduce or eliminate breakage. Embedding the tines (as opposed to gluing them) reduces or eliminates dislodging of the tines in operation. In addition, the hold down brush can be made into a number of small brush segments, which can facilitate quick and easy replacement and maintenance.

A printer is provided with a roll paper holding portion that holds roll paper without axially supporting the roll paper; a sheet conveying unit that conveys a sheet supplied from the roll paper; a printing unit that executes printing on the sheet; and a roll paper pressing unit that presses the roll paper held in the roll paper holding portion, wherein the roll paper pressing unit is provided with a pressing roller that presses the roll paper and rotates along with the sheet conveyance, and a rotation suppressing portion that suppresses the rotation of the pressing roller.

A unit attaching detaching structure includes: a unit that is attachable to and detachable from an apparatus main body; a displacement portion that is provided on the apparatus main body and is displaceable to one side and another side; a detection unit that detects attachment of the unit when the displacement portion is displaced from the another side to the one side; a connecting portion that is separated from the detection unit in a direction intersecting with a direction of attaching/detaching of the unit, and is connected to the displacement portion so as to displace the displacement portion; a movement portion that is provided on the unit and displaces the displacement portion by moving the connecting portion when the unit is attached to the apparatus main body; and a returning unit that returns the displacement portion when the unit is detached from the apparatus main body.

A sheet discharging apparatus includes a discharging unit configured to discharge a sheet such that the sheet nipped between a first roller and a second roller is warped as viewed from a downstream side in a sheet discharge direction, a sheet supporting member configured to support the sheet discharged by the discharging unit, a first charge-removing portion configured to remove electrostatic charges of the sheet by coming into contact with the sheet at a position downstream of a position where the first roller and the second roller nip the sheet in the sheet discharge direction, and a second charge-removing portion configured to remove electrostatic charges of the sheet by coming into contact with the sheet at a position downstream of the position where the first charge-removing portion comes into contact with the sheet in the sheet discharge direction.

A printing apparatus includes a transport unit that transports a medium in a transport direction, a printing unit that prints on a printing surface of the medium, and a removal unit that is provided on an upstream side in the transport direction with respect to the transport unit and is provided so as to come into contact with the printing surface.

A brush roll configured to support a material web, in particular a web of corrugated board, comprises a roll core and arcuate shells, which are each arranged on the roll core and comprise bristles arranged on the outside. The brush roll further has fastening assemblies configured to fasten the arcuate shells to the roll core. Each of the fastening assemblies has a fastening body, which is locally fastened to the roll core, which locally fastens at least one of the arcuate shells to the roll core, which has a foot part, connected to the roll core, with a bottom, and a head part, connected to the foot part, with a lower side facing the roll core, said lower side forming at least one lower wedge face for engagement with at least one of the arcuate shells.

A printer is provided with a roll paper holding portion that holds roll paper without axially supporting the roll paper; a sheet conveying unit that conveys a sheet supplied from the roll paper, a printing unit that executes printing on the sheet; and a roll paper pressing unit that presses the roll paper held in the roll paper holding portion, wherein the roll paper pressing unit is provided with a pressing roller that presses the roll paper and rotates along with the sheet conveyance, and a rotation suppressing portion that suppresses the rotation of the pressing roller.

A sheet discharging device includes a stacking portion configured to stack a sheet; a discharging portion configured to feed the sheet so as to be discharged to the stacking portion, wherein the discharging portion includes a first roller configured to feed the sheet and a second roller provided so as to be contactable to a sheet surface opposite from another sheet surface to which the first roller is contactable to; and an electrically discharging member configured to electrically discharge the sheet in contact with the sheet fed by the discharging portion. As viewed in a widthwise direction perpendicular to a discharging direction of the sheet, the electrically discharging member is provided so as to extend through between rotational axes of the first and second rollers in the discharging direction of the sheet.
