Abstract
An image reading apparatus includes pairs of rollers, each including a driving roller and a driven roller. The pairs of rollers are arranged along the rotation axis direction of the driving roller and constitute a first roller group and a second roller group for conveying a first medium and a second medium thicker than the first medium, respectively. The center of the first roller group is identical in the rotation axis direction to that of a first conveying area where the first medium is conveyed. The center of the second roller group is identical in the rotation axis direction to that of a second conveying area where the second medium is conveyed. At least one pair of rollers in the second roller group is arranged outside the first roller group within the first conveying area.
