More Information
Summary:In the paper feeding roller, a shaft body has a cantilever structure supported at one end, and an elastic layer includes a supported end and a free end on both ends along a rotation axis, wherein an outer diameter of the free end in a cross section orthogonal to the rotational axis is greater than that of the supported end, and an area including the free end has a widened bottom part having an outer diameter which widens in a linear or inner convex manner approaching the free end along the rotation axis. The paper feeding device includes a feed roller rotationally driven and conveying paper, and a retard roller pressed against the feed roller, affixed with a torque limiter, and suppressing double feeding of paper. At least one of the feed roller and the retard roller is formed as the paper feeding roller.
