Abstract: A document reader has a main conveying path, an auxiliary conveying path, a pickup roller, a first conveying roller, and a second conveying roller. The auxiliary conveying path runs between a first connection point and a second connection point on the main conveying path. The cylindrical surface of the first conveying roller is located partially on the main conveying path and partially on the auxiliary conveying path. While the first conveying roller is under the forward or reverse control, it rotates normally. The cylindrical surface of the second conveying roller is located partially on the main conveying path between the second connection point and a discharge position. A controller switches from the forward control selected during this mode to the reverse control, while a document being conveyed along the main conveying path is out of contact with the first conveying roller.

Abstract: The document read apparatus according to the present invention has a light source unit that includes a linear first light and second light sources, both light sources aligned parallel to the sub scanning direction (moving direction). When the light source unit is scanning a book document in a second region shifted toward a side of the first light source from a center position for emitting light to the center of the document, a light quantity of the second light source becomes larger than a light quantity of the first light source. When the light source unit is scanning the book document in a third region shifted toward a side of the second light source from the center position, the light quantity of the first light source becomes larger than the light quantity of the second light source. A sum of both light quantities is controlled to be constant.
