Abstract: An image reading device includes a casing, an image reading unit, a mounting board, and an antenna. The casing has a side wall positioned at one end thereof in a first direction. The image reading unit is accommodated in the casing and configured to read an image of an original document by scanning in the first direction. The mounting board is accommodated in the casing and mounts an electronic component that is used when the image reading unit reads the image, the mounting board extending in the first direction. The antenna is accommodated in the casing and configured to receive or transmit a radio signal. The antenna is disposed along and adjacent the side wall.

Abstract: A sheet feeder including a driving mechanism moving a stopper, an end of the stopper in a first position being closer to a pickup roller axis than a part of a roller surface of a pickup roller, the end of the stopper in a second position being farther from the pickup roller axis than the part of the roller surface, and a movable set guide having a first surface facing in a particular direction to become farther from the roller surface, the first surface being farther from the pickup roller axis than all the roller surface when the set guide is in a third position and contacts the stopper in the first position, the first surface being closer to the pickup roller axis than the part of the roller surface when the set guide is in a fourth position and separated away from the stopper in the second position.

Abstract: A sheet feeder is provided that includes a housing, a feed tray having a loading surface, and a swingable opening cover including a sliding contact portion, extending in a direction perpendicular to a width direction of a sheet. The sliding contact portion is configured to slide in contact with a feed tray in a swing motion of the feed tray from a first position where the loading surface is directed downward above the housing to a second position where the loading surface is directed upward at an upstream side relative to the housing in a feeding direction. The sliding contact portion is disposed on at least one end of the opening cover in the width direction, and exposed to an outside of the sheet feeder when the feed tray is in the first position.
