    摘要: An arrangement is provided such that a pad pressing means for pressing a separation pad against a pick roller is formed in a reverse U-shape, and a pressing spring for pressing the pad pressing means to press the separation pad against the pick roller is provided on a central portion of the pad pressing means. The pad pressing means is structured so as to have a rotating fulcrum to be rotatable back and forth with respect to a rotating direction of the pick roller about a connecting portion of the pad pressing means for connection to the pressing spring. To ensure that a large load will not be applied to the entire pad pressing means when thick paper or the like is fed, a rotating arm may be provided so that the entire pressing means including the pad pressing means is rotatable about a predetermined position set at the rotating fulcrum which is the connecting portion for connection to the pressing spring.

    摘要: 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. The spring unit and the pad units are supported together by a bracket 76 and a holder member 78.
