A recording apparatus includes a recording unit configured to perform recording on a recording medium that is a long medium, a supporting part disposed opposite to the recording unit and configured to support the recording medium, a cutting part configured to cut the long medium into a single sheet medium, a guide member configured to guide the recording medium, a winding unit configured to wind up the long medium, and a medium housing unit configured to be detachable and house the single sheet medium. The guide member is displaceable to a first supporting position in which the guide member supports the recording medium being conveyed to the medium housing unit and a second supporting position in which the guide member supports the long medium being conveyed to the winding unit, the second supporting position being located above the first supporting position.

A housing is provided with a sheet ejection port for discharging sheet that passed through a printing unit upward. A cutting unit is arranged between the printing unit and the sheet ejection port and cuts the sheet by either a method of cutting the sheet in the entire width direction or a method of leaving the central portion of the sheet in the width direction. First protrusions and second protrusions protruding from the inner periphery of the sheet ejection port are provided at a plurality of locations along the width direction of the sheet. The first protrusion faces a first surface of the sheet and the second protrusion faces a second surface, which is the back surface of the first surface of the sheet. The first protrusion and the second protrusion are provided at positions deviated from each other in the sheet width direction and bend the sheet in an undulating shape in the width direction therebetween. Further, protrusion height of at least one of the first protrusions and the second protrusions in the central portion in the width direction of the sheet is lower than protrusion heights of the first protrusions and the second protrusions in other regions.

A printer provided with a storing space for a paper roll having a core hole in the center includes a paper roll holder having a protrusion adapted to fit into the core hole of the paper roll. The paper roll holder is switchable between a protruded state that the protrusion protrudes into the storing space and a retracted state that the protrusion retracts from the storing space. The printer further includes a stopper adapted to engage with the paper roll holder while the paper roll holder is in the protruded state to prevent the protrusion from turning to a predetermined direction. The paper roll holder moves when pushed by the paper roll that is being set into the storing space. Movement of the paper roll holder releases the engagement with the stopper to allow the protrusion to turn to the predetermined direction.

A medium placement device configured to stack a plurality of sheets of a medium discharged from a discharge unit of a processing device, the medium placement device including a plurality of support units being provided in a width direction intersecting with a discharge direction of the medium, and being configured to support, on a support surface from below in a gravitational direction, the medium discharged from the discharge unit. The plurality of support units are provided extending in the discharge direction, and are inclined downward in a gravitational direction from upstream to downstream in the discharge direction, and a first support unit and a second support unit arranged at a lower position in the gravitational direction with respect to the first support unit as viewed in the width direction, the first support unit and the second support unit being arranged alternatingly in the width direction.

An image forming apparatus, including: a sheet cassette; an image former; a fixer; a discharge tray; a conveyor configured to convey a sheet along a conveyance passage; a return conveyor configured to convey the sheet from a branch position between the fixer and the discharge tray to a merge position between the sheet cassette and the image former along a return passage which is branched from the conveyance passage at the branch position, passes below the sheet cassette, and merges with the conveyance passage at the merge position; a switchback roller disposed between the branch position and the discharge tray in the conveyance passage and configured to convey the sheet to the discharge tray when it rotates forwardly and to the return passage when it rotates backwardly; and an intermediate conveyance roller disposed in the return passage at a height level intermediate between the fixer and the sheet cassette.

A recording apparatus includes: a housing; a recording device that is provided inside the housing; a medium receiving tray moves between a first position and a second position, the first position being housed inside the housing, the second position being a position of protruding from the housing; a guide for guiding the medium receiving tray; and a guided portion of the medium receiving tray being guided by the guide, wherein the guide includes a first guide area and a second guide area, wherein the first guide area is guiding the guided portion from the first position to a third position that is located between the first position and the second position before the second position, wherein the second guide area is guiding the guided portion from the third position to the second position, and wherein the second guide area includes a narrowing area narrower than the first guide area.

Provided is a control unit of a conveying apparatus, the conveying apparatus including: a conveying unit that conveys recording paper along a conveying path; and an imaging unit that images the recording paper and an object not conveyed by the conveying unit, wherein the control unit acquires actual conveyance information of the recording paper from image information of the recording paper imaged by the imaging unit and image information of the object imaged by the imaging unit.

According to an embodiment, a printer includes a drop portion that catches, in a case where a diameter of a roll of paper stored in a holder becomes small, the roll of paper that falls from the holder. The printer further includes a plurality of support rollers that are arranged so as to sandwich an inlet of the drop portion and rotatably support the roll of paper PR stored in the holder. At least one of the plurality of support rollers is a short-width roller whose width in an axial direction of a shaft is shorter than a paper width of the roll of paper PR, and a void is provided at a non-shaft arrangement part provided at an extension portion of the short-width roller in the axial direction.

Examples of the present disclosure relate generally to a printing apparatus and, more particularly, to apparatuses, systems, and methods for printing utilizing laser print head and reactive media.

A medium discharge device includes a discharge roller pair that is provided with a discharge driving roller and a discharge driven roller which drivably rotates in contact with the discharge driving roller, and a medium receiving tray which receives the medium that is fed and discharged by the discharge roller pair, in which the medium receiving tray includes a guide member which guides such that a tip end of the medium which is discharged from the discharge roller pair enters the medium mounting surface at a predetermined angle, and the guide member is provided to be elastically displaceable in an advancing and retreating direction with respect to the medium mounting surface of the medium receiving tray and is displaced in a direction coming close to the medium mounting surface according to raising of a pressing load due to the medium that is discharged to the medium receiving tray.
