Abstract:
1. An image reading device comprising: a document feeding unit capable of covering and uncovering a top surface of a document platen; and an image reading unit having a top surface provided with the document platen and a reading glass plate located adjacent to one end of the document platen and configured to read an image of a document placed on the document platen and an image of a document fed from the document feeding unit and passing the reading glass plate, wherein: the document feeding unit includes: the image reading unit includes a dent portion accommodating the protruding portion of the document feeding unit and located opposite away from the document platen across the reading glass plate; the feeding means includes a feeding guide forming part of a bottom surface of the feed path and having a downstream end in a document feeding direction of the feed path which serves as a supporting point and an upstream-side portion extending upstream of the supporting point and supported at the supporting point for pivotal movement about an axis parallel with a direction perpendicular to the document feeding direction; the upstream-side portion of the feeding guide is exposed out of the protruding portion on the document platen side; when the document feeding unit is closed while a document is in a state of failing to extend off the document platen onto the dent portion of the image reading unit, the upstream-side portion of the feeding guide descends by its own weight to form part of the feed path; and when the document feeding unit is closed while the document is in a state of extending off the document platen onto the dent portion, the upstream-side portion of the feeding guide is pressed up by the document to move into an upper position.
