Abstract: A sheet feed device includes a housing, a tray, a feed roller, an arm, a pad, and a protruding portion. The housing has a sheet conveyance path. The tray includes a bottom plate having a sheet support surface that supports a sheet. The sheet conveyance path extends upward from the sheet support surface. The feed roller rotates about a rotational axis and feeds the sheet supported on the sheet support surface in a first direction. The arm rotatably supports the feed roller. The arm swingably moves about an axis parallel to the rotational axis of the feed roller. The pad is disposed on the bottom plate. The pad has a higher friction coefficient than a friction coefficient of the sheet support surface. The protruding portion protrudes upward from the sheet support surface at a position shifted from the pad in a second direction opposite from the first direction.

Abstract: A front plate is rotatably supported at an end portion of a tray in a pulling direction. The front plate rotatably moves between: a first position at which the front plate extends diagonally upward in the pulling direction from a first end portion at which a rotational axis is located toward a second end portion opposite the first end portion; and a second position at which the second end portion of the front plate is located at a position that is higher than the second end portion at the first position and that is shifted in an insertion direction from the second end portion at the first position. The front plate includes a grip and a surface. The surface of the front plate faces in the pulling direction and downward in a state where the front plate is located at the first position, wherein the surface surrounds the grip.

Abstract: An image forming apparatus includes a housing, a feeding tray inserted into and pulled out from the housing, an image forming unit, and first and second guide members. The feeding tray includes a first accommodation part in which a roll body having a configuration where a sheet-shaped medium is rolled in a roll shape is accommodated and a second accommodation part in which stacked sheet-shaped media are accommodated. The first guide member guides a sheet-shaped medium to a conveying path. The second guide member guides a roll medium unrolled from the roll body to the conveying path. The second guide member is movable between a guide position for guiding the roll medium to the conveying path, and a retreat position further distant from the first guide member than the guide position and where the second guide member does not interfere with a sheet-shaped medium accommodated in the second accommodation part.

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.
