Abstract
【解決手段】カバー部200がプラテンガラス120を覆う閉じた状態において、原稿搬送部250は、補強部材230に対して上下方向移動可能に水平方向の位置決めされ且つ脚部284、288が読取部100の上面部110におけるプラテンガラス120又はその周囲に当りプラテンガラス120を基準として上下方向に位置決めされる。原稿高さ規制部材300(規制部310)は、補強部材230に上下方向移動可能に水平方向に位置決めされ且つ規制部材300のリブ334がプラテンガラス120に当り上下方向に位置決めされる。したがって、プラテンガラス120の原稿読取領域122における原稿搬送経路Kのばらつきが抑制される。
