To provide a technique that can determine whether a document can be read before the start of reading to prevent the occurrence of unnecessary processing time.SOLUTION: An image reading device comprises: conveying means that conveys a document 202; and reading means 703-707 that read an image of the document 202 conveyed by the conveying means, and the image reading device comprises: a detection unit that detects the inclination and width of a leading end of the document 202 before the start of reading of the image performed by the reading means 703-707; and a determination unit that, before the start of reading of the image performed by the reading means 703-707, determines whether the posture of the document 202 acquired from a result of detection performed by the detection unit is a posture allowing the reading of the image performed by the reading means 703-707.SELECTED DRAWING: Figure 5 【課題】原稿の読取の可否を読取の開始前に判定することで、無駄な処理時間の発生を抑制することができる技術を提供する。【解決手段】原稿２０２を搬送する搬送手段と、搬送手段によって搬送される原稿２０２の画像を読み取る読取手段７０３〜７０７と、を備える画像読取装置において、読取手段７０３〜７０７による画像の読取の開始前に、原稿２０２の先端部の傾きと幅を検知する検知部と、読取手段７０３〜７０７による画像の読取の開始前に、検知部の検知結果から取得される原稿２０２の姿勢が、読取手段７０３〜７０７による画像の読取が可能な姿勢であるのか否かを判定する判定部と、を備えることを特徴とする。【選択図】図５
