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.
