Abstract: A medium unit, having a tray, a casing, and a pullback assembly, is provided. The tray stores a roll of medium, in which a continuous medium is rolled. The casing supports the tray detachably attached thereto. The pullback assembly pushes the continuous medium from a lower side to pull a loose end of the continuous medium unrolled from the roll of medium in conjunction with a detaching action to move the tray to detach from the casing in an orthogonal direction intersecting orthogonally with a rotation axis of the roll of medium.

Abstract: An image recording apparatus includes a feed tray, a feed mechanism feeding a sheet-shaped medium accommodated in the feed tray, and a recording device recording an image on the sheet-shaped medium fed by the feed mechanism. The feed tray includes a first accommodation portion accommodating a roll, in which the sheet-shaped medium is rolled, a pair of side walls interposing the sheet-shaped medium unrolled from the roll in a first direction parallel to an axis of the roll, and a side guide disposed inside the pair of side walls and having an inner-side surface contactable with an edge in the first direction of the first sheet-shaped medium unrolled from the roll. The side guide has a metal portion made of metal, the metal portion forming at least part of the inner-side surface.

Abstract: A three-dimensional shaped object can achieve both of a property in the case of a high dense degree and a property in the case of a low dense degree, and have a high strength. The three-dimensional shaped object includes a dense portion formed on one side so as to be dense, and a porous portion formed on an opposite side so as to be porous. The dense portion and the porous portion are formed by a reaction product of a ceramic material with a chelating agent.

Abstract: An image recording apparatus includes a conveyance mechanism conveying a sheet-shaped medium in a conveyance direction, a recorder recording an image on the conveyed sheet-shaped medium, and a controller. The conveyance mechanism selectively conveys a first sheet-shaped medium accommodated in a first accommodation part, and a second sheet-shaped medium accommodated in a second accommodation part and longer than the first sheet-shaped medium in the conveyance direction. The controller causes, based on a recording command, the conveyance mechanism to convey a sheet-shaped medium from one of the first and second accommodation parts, and causes the recorder to record an image on the sheet-shaped medium.

Abstract: An image recording apparatus includes a controller to calculate n that is a maximum natural number satisfying nX?X0, where X0 represents a width of a sheet medium, and X represents a longest one of respective lengths, in a width direction of the sheet medium, of a plurality of first images or a single second image based on image data. The plurality of first images are arranged along a longitudinal direction of the sheet medium. When the calculated n is equal to or more than two, the controller performs a juxtaposed image recording process to control a print engine in such a manner that two or more and n or less images, among the plurality of first images or among a plurality of divisional images into which the single second image is divided, are recorded to be arranged side by side along the width direction.

Abstract: 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.

Abstract: A liquid ejection apparatus includes a medium container, a liquid ejection head, a mover, and a controller. The mover is configured to execute, among a first moving operation of moving a sheet-like medium and a second moving operation of moving the liquid ejection head, at least the first moving operation. The controller causes the liquid ejection head and the mover to alternately or simultaneously perform execution of the first moving operation and execution of ejection and second moving operations, and adjusts at least one selected from the group of an amount of liquid to be ejected, a time interval between the ejection operations when alternately performing execution of the first moving operation and execution of the ejection and second moving operations, and a moving speed of the medium when simultaneously executing the ejection operation and the first moving operation, according to medium information relating to curling of the medium.

Abstract: A feed mechanism includes: a feed tray accommodating a roll body, a first sheet-shaped medium being rolled in a roll shape as the roll body, the feed tray including: a first accommodation portion accommodating the roll body; a pair of side walls respectively provided on both sides of the first accommodation portion in an axial direction of the roll body that is accommodated in the first accommodation portion; and a side guide disposed inside the pair of side walls.
