PROBLEM TO BE SOLVED: To easily take out one of a pair of rollers.SOLUTION: An automatic document conveyance unit includes: a retard roller 6 and a separating/conveying roller for conveying a sheet by contacting each other; a document guide path for guiding the sheet; a retard roller holder 19 which holds the retard roller 6; a conveying guide 21 supporting the retard roller holder 19 and constituting the bottom face of the document guide path; and a spring disposed between the retard roller holder 19 and the conveying guide 21. When the document guide path is opened, the spring allows the retard roller holder 19 to extrude above the conveying guide 21, which makes it easier for a user to hold a rib 181 and take out the retard roller 6 from the retard roller holder 19. |
