A recording device has: a recording head configured to perform recording on a medium; a medium storage below the recording head configured to store the medium to be recoded; a supply path comprising a first curved supply path curved so as to be convex upward and transporting the medium fed out of the medium storage in a reversed direction via the first curved supply path; and a reversing path comprising a second curved path curved so as to be convex downward and transporting the recorded medium into a direction including a vertically upward component via second curved path from a direction including a vertically downward component; wherein the supply path joins the reversing path, and the first curved path and the second curved path overlap when viewed horizontally.

A recording apparatus includes a cassette or a feeding tray that is configured to mount a medium thereon, a transport unit that transports the medium mounted on the cassette or the feeding tray, and a recording head that performs recording on the medium. Furthermore, the recording apparatus includes a medium detection device and a deviation amount acquisition section. The medium detection device detects at least one of both side edges in a width direction intersecting a transport direction of the medium that is transported from the cassette or the feeding tray (step S12). The deviation amount acquisition section acquires a deviation amount of the recording head in the width direction of the medium based on at least one side edge detection position detected by the medium detection device (step S13).

A printer includes: a conveyor conveying a sheet in a conveying direction; a first supporting part positioned on an upstream side in the conveying direction with respect to the conveyor, and having a first supporting surface; a side guide making contact with at least one of both ends, in a width direction of the sheet, in the first supporting surface, the width direction being orthogonal to the conveying direction and parallel to the first supporting surface; a suction-attraction force generator generating a suction-attraction force in an area, in the first supporting surface, which is adjacent to the side guide and in which the sheet passes; a second supporting part positioned on a downstream side in the conveying direction with respect to the conveyor, and having a second supporting surface; and a recording part recording an image on the sheet supported by the second supporting surface.

A printer extension kit that modifies a printer to receive and output longer pieces of paper. The printer extension kit includes an input extension part, an output extension part, and an output extension clip. The paper tray of a printer is extended by the input extension part allowing the printer to hold longer pieces of paper. The input extension part is attached to the paper tray of a printer. The output extension part allows a printer to output longer pieces of paper. In more detail, the output extension part prevents longer pieces of paper from falling of the catch tray of a printer. The output extension part is attached into the catch tray of a printer. The output extension clip provides another means for a printer to output longer pieces of paper. In more detail, the output extension clip is attached along the output paper catch of a printer.

An image forming apparatus includes a controller that performs one or more times a first image forming process including performing image formation on a sheet medium, and conveying the sheet medium in a conveyance direction by rotating a first roller by a first number of rotations and rotating a second roller disposed downstream of the first roller in the conveyance direction by a second number of rotations smaller than the first number of rotations. When a count of times the first image forming process has been performed becomes a particular number of times, the controller performs a second image forming process including performing image formation on the sheet medium, and conveying the sheet medium by rotating the first roller by a third number of rotations smaller than the first number of rotations and rotating the second roller by the second number of rotations.

A sheet feeding device, which is included in an image forming apparatus and includes a device attachment body, includes a sheet container configured to accommodate a sheet, a support configured to support a lower face of the sheet in the sheet container, a sheet width regulator configured to regulate a position of the sheet in a sheet width direction, a conveying force applier configured to apply a sheet conveying force in a sheet conveying direction to the sheet in the sheet container, and a sheet guide disposed above the sheet in the sheet container and configured to regulate movement of the sheet in an upper direction.

A printer includes a print head and a platen roller. The platen roller includes multiple bearings provided one at each longitudinal end of the platen roller, a roller positioned between the bearings, and multiple flanges of which one is positioned between the roller and one of the bearings and the other is positioned between the roller and the other of the bearings in the longitudinal direction of the platen roller. The flanges have a diameter greater than the diameter of the bearings and the diameter of the roller.

The electrodes are located on the substrate and are connected to the heat-generating portion. The protective layer covers the heat-generating portion and parts of the electrodes. A skewness Rsk of the protective layer is larger than 0. Further, A thermal head of the present disclosure includes a substrate, a heat-generating portion, electrodes, and a protective layer. The heat-generating portion is located on the substrate. The electrodes are located on the substrate and are connected to the heat-generating portion. The protective layer covers the heat-generating portion and parts of the electrodes. A kurtosis Rku of the protective layer is larger than 3.

A recording device has: a recording head configured to perform recording on a medium; a medium storage below the recording head configured to store the medium to be recoded; a supply path comprising a first curved supply path curved so as to be convex upward and transporting the medium fed out of the medium storage in a reversed direction via the first curved supply path; and a reversing path comprising a second curved path curved so as to be convex downward and transporting the recorded medium into a direction including a vertically upward component via second curved path from a direction including a vertically downward component; wherein the supply path joins the reversing path, and the first curved path and the second curved path overlap when viewed horizontally.

A roll paper printer includes an accommodation section configured to accommodate roll paper wound such that one surface of recording paper faces outward, a transport roller configured to pull the recording paper from the roll paper and transport the paper in a transport direction, a guide positioned upstream of the transport roller in the transport direction and configured to come into contact with the other surface of the recording paper, and a protrusion positioned upstream of the transport roller in the transport direction and configured to come into contact with the one surface of the recording paper, the protrusion being configured to move toward the guide.
