Provided is an apparatus that can reduce a braking force of a medium separating mechanism to thereby reduce occurrence of paper jams only by attaching a medium supply device to an image forming apparatus body. The medium supply device is configured to be attached to an image forming apparatus body including a medium separating mechanism, and includes a medium conveying mechanism that supplies a recording medium from stacked recording media to a predetermined position, and first mechanism that reduces a braking force generated in the medium separating mechanism.

An inkjet printer including a feeding device configured to feed a sheet in a feeding direction, a platen configured to support the sheet, a recording device configured to eject ink on the sheet, contacting members configured to contact the sheet, a detector configured to detect an end portion position of the sheet in a width direction, and a controller configured to control the feeding device and the recording device is provided. The contacting members are arranged at intervals in the width direction, and the controller performs a suppression process in which at least one of the feeding device and the recording device is controlled to suppress a contact of the sheet with the recording device when the end portion position detected by the detector is a position between the two adjacent contacting members.

A printing apparatus includes a conveying unit which conveys a printing medium in a conveying direction; a printing unit which prints an image on the printing medium conveyed by the conveying unit; a processing unit which includes a processing member and which executes a processing action for processing the printing medium by moving the processing member while causing the processing member to contact the printing medium; and a controller. The controller executes a processing process for causing the processing unit to execute the processing action with respect to the printing medium by moving the processing unit from a first position to a second position in an intersecting direction; a first conveying process for causing the conveying unit to convey a processed printing medium in the conveying direction; and a first moving process for moving the processing unit from the second position to the first position after the first conveying process.

An image forming device performs image formation on a medium selected by a computer. When a cutting device is unusable, a long sheet-type medium accommodated in a first medium container is unusable. However, a conveyance passage used for conveying a short sheet-type medium is usable in at least one of a first state where the cutting device is unusable or a second state where the sheet-type medium is unable to pass through the cutting device. A necessary condition to make both the long sheet-type medium and the short sheet-type medium selectable includes the detector detecting neither the first status nor the second status. A necessary condition to make the long sheet-type medium unselectable and make the short sheet-type medium selectable includes the detector detecting one of the first status and the second status.

A printer housing with an upper portion and a lower portion with a cavity there between and wherein the upper portion and lower portion are connected by one or more hinges such that the housing opens about the hinged connection between the upper portion and the lower portion to expose the cavity there between. The hinged connection allows the upper portion to be lifted up with respect to the lower portion to expose one or more printer components for access through the cavity. One or more hinges secure the upper portion to the lower portion and wherein the one or more hinges are positioned on a same perimeter side of the housing such that the housing opens about one side.

A printing apparatus includes a conveyance path including a curving part, an inversion path for inverting a medium upside down, and a control unit, and the control unit includes a first mode for conveying the long medium at a first speed when a surface that faces inside when the long medium is rolled in a roll shape and a surface that faces inside when conveyed in a curved shape through the curving part are the same, and a second mode for conveying the long medium at a second speed lower than the first speed of the first mode when the surface that faces inside when the long medium is rolled in the roll shape and the surface that faces inside when conveyed in the curved shape through the curving part are different from each other.

Provided is a control unit of a conveying apparatus, the conveying apparatus including: a conveying unit that conveys recording paper along a conveyance path; an imaging unit that images the recording paper; and a light emitting unit arranged on an opposite side of the imaging unit across the conveyance path, wherein the control unit detects conveyance information of the recording paper based on image information of the recording paper imaged by the imaging unit in a state in which light from the light emitting unit is transmitted through the recording paper. The control unit detects the conveyance information of the recording paper based on a plurality of images of the recording paper imaged at different timings by the imaging unit.

A printing apparatus includes: a driving roller configured to drive a recording medium by rotation thereof while being in contact with the recording medium; a discharging head configured to discharge liquid onto a recording medium; a driven rotational member configured to be driven to rotate as a result of transport of the recording medium while being in contact with the recording medium; a rotation position detection unit configured to detect a rotation position of the driven rotational member; and a control unit configured to rotate the driving roller to transport the recording medium and adjust a timing of discharging the liquid from the discharging head in accordance with a detection result of the rotation position detection unit. The control unit adjusts a rotational speed of the driving roller in accordance with a linear pressure applied to the recording medium on the driving roller.

An image recording apparatus, including: a main body; an image recorder; a sheet supporter movable between an opposed position and a retracted position; a cap movable between a contact position and a distant position; a distance-defining member movable between a first position and a second position and configured to define a distance between an upper surface of a sheet and a lower surface of the recorder, the first position being a position where the member partially overlaps a region of the cap at the contact position, the second position being a position where at least a part of the member does not overlap the region; and a controller to control the cap to move from the distant position to the contact position after the supporter has been moved from the opposed position to the retracted position and the member has been moved from the first position to the second position.
