Abstract: An automatic paper feeder of a document input device includes a pick roller 20, separator pads 68 that come into contact with the pick roller 20, a first pair of pick springs 58, and a second pick spring 60. The first pick springs 58 are disposed on the upstream side of the second pick spring 60 in the direction of conveying the paper. The first pick springs 58 are disposed on the regions on both outer sides of the width of the separator pads 68 in the axial direction of the roller, and the second pick spring 60 is disposed at a central position in the width of the separator pad 68. The first and second pick springs 58 and 60 are integrally formed as a spring unit using a single metal plate, and a force of contact of the first pick springs 58 upon the pick roller 20 on the upstream side is smaller than a force of contact of the second pick spring 60 upon the pick roller 20 on the downstream side. The separator pad 68 is formed by branching a web 70 of a rubber sheet into fork-like pad units.
