To solve a problem in a sheet feed type scanner that, when it is miniaturized, a size of a sub supply tray becomes smaller so that it is hard to appropriately support a manuscript to be transported.SOLUTION: An image reading device includes: a device body having a reading unit for reading an image of a manuscript to be transported; a manuscript supporting unit which is positioned upstream of the reading unit, and supports the manuscript to be transported; and a deployment supporting unit which can be housed and deployed to/from the manuscript supporting unit, and supports the manuscript to be fed together with the manuscript supporting unit by being deployed from the manuscript supporting unit. The deployment supporting unit includes: a first deployment unit which can perform storage and deployment, by rotating to the manuscript supporting unit, and extends in a width direction being a direction crossing the manuscript feed direction in a state stored in the manuscript supporting unit; and a second deployment unit which can perform storage and deployment to the first deployment unit, and extends in the width direction in a stored state of the deployment supporting unit.SELECTED DRAWING: Figure 11 【課題】シートフィードタイプのスキャナーでは、小型化するとサブ供給トレイの給送方向のサイズが小さくなってしまい、給送する原稿を適切に支持できなくなる。【解決手段】画像読取装置は、搬送される原稿の画像を読み取る読取部を備える装置本体と、前記読取部の上流に位置し、給送される原稿を支持する原稿支持部と、前記原稿支持部に対し収納及び展開可能であり、前記原稿支持部から展開されることで前記原稿支持部とともに給送される原稿を支持する展開支持部と、を備え、前記展開支持部は、前記原稿支持部に対して回転することで展開及び収納可能な展開部であって、前記原稿支持部に収納された状態において原稿給送方向と交差する方向である幅方向に沿って延びる第１展開部と、前記第１展開部に対し収納及び展開可能な展開部であって、前記展開支持部の収納状態において前記幅方向に沿って延びる第２展開部とを備える。【選択図】図１１
