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.
