A sheet conveyor including a separation roller, a separation pad, an urging member urging the separation pad, and a feed roller unit disposed downstream relative to the separation roller in a conveyance direction, the feed roller unit including a first outer circumferential surface disposed on a first side in a width direction perpendicular to the conveyance direction, a second outer circumferential surface disposed on a second side opposite to the first side in the width direction, and a concave portion disposed between the first and second outer circumferential surfaces in the width direction, the concave portion being recessed inward in a radial direction of the first and second outer circumferential surfaces from the first and second outer circumferential surfaces, an urging member being disposed upstream relative to the concave portion in the conveyance direction and disposed between the first and second outer circumferential surfaces in the width direction. |

1. A sheet conveyor comprising:
a separation roller configured to convey one or more sheets downstream in a first direction; a separation pad disposed to face the separation roller, the separation pad being configured to separate the one or more sheets on a sheet-by-sheet basis in cooperation with the separation roller; a supporter configured to support the separation pad, the supporter being swingable around a swing axis, the swing axis being positioned upstream of the separation roller in the first direction, the swing axis extending in a second direction perpendicular to the first direction; a first urging member configured to urge the separation pad against the separation roller by urging the supporter in a direction toward the separation roller; and a feed roller disposed downstream of the separation roller in the first direction, the feed roller being configured to convey the one or more sheets separated by the separation roller and the separation pad, downstream in the first direction, the feed roller comprising:
a first outer circumferential surface having a first radius around a rotational axis of the feed roller, the rotational axis extending in the second direction;a second outer circumferential surface having a second radius around the rotational axis of the feed roller, the second radius being identical to the first radius, the second outer circumferential surface being spaced apart from the first outer circumferential surface in the second direction; anda recessed portion disposed between the first outer circumferential surface and the second outer circumferential surface in the second direction, the recessed portion being recessed inward in a radial direction of the feed roller relative to each of the first outer circumferential surface and the second outer circumferential surface, wherein the first urging member is disposed upstream of the recessed portion in the first direction and disposed between the first outer circumferential surface and the second outer circumferential surface in the second direction, the first urging member being configured to urge the supporter in such a position as not to overlap the separation pad when viewed in a third direction, the third direction being perpendicular to each of the first direction and the second direction. |
