Abstract:
1. A scanner apparatus comprising: a reading unit that reads a surface of a medium; a curved inverting transport path that transports a medium, that is arranged in an upstream side of the reading unit; a medium guide member that forms part of an upstream side of the curved inverting transport path and guides the medium to a downstream side, and that is provided so as to be capable of pivoting at an outward side from the curved inverting transport path, and that changes the size of a space of part of the curved inverting transport path by pivoting; a first feeding roller that includes a first driving roller capable of forward rotation and a first slave roller that nips the medium with the first driving roller, that is provided in the upstream side of the curved inverting transport path; and a second feeding roller that includes a second driving roller capable of forward and reverse rotation and a second slave roller that nips the medium with the driving roller, that is provided in a downstream side of the curved inverting transport path, wherein the medium guide member has a pivot axis that is in an upstream side of the medium guide member, wherein the curved inverting transport path keeps a curved shape when the medium guide member is pivoted, wherein cooperation of the first feeding roller and the second feeding roller to remove skew bulges the medium outwardly in the curved transport path, wherein when the first feeding roller and the second feeding roller cooperate to remove skew, the medium exerts a force on the medium that is orthogonal to a radial direction of the pivot axis, and the medium guide member pivots to the outward side.
