Abstract
A sheet feeder includes: a feed roller; a shutter movable between a restricting position restricting a leading edge of a sheet and a non-restricting position releasing the restriction on the sheet; and a controller configured to control rotation of the feed roller and movement of the shutter. The controller is configured to perform: a first feeding process of controlling the feed roller to rotate at a first rotational speed while the shutter is at the restricting position and of controlling the shutter to move to the non-restricting position from the restricting position no earlier than rotation of the feed roller at the first rotational speed: a reduction process of controlling a rotational speed of the feed roller to be less than the first rotational speed; and a second feeding process of controlling the feed roller to rotate at a second rotational speed.
