Abstract:
1. A medium feeding device comprising: a base; a plurality of spaced-apart ribs contacting a bottom surface of a medium, each rib protruding from said base and defining a feeding path along which the medium is fed, each rib having a length measured in a direction along which the medium is fed, each rib having a width measured in a direction perpendicular to the length, each rib having a height measured in a direction perpendicular to both the length and the width, the length of each rib being greater than the height of each rib, each rib having two sidewalls opposing each other in the widthwise direction of each rib, each rib being entirely disposed within a width of the medium and entirely below the medium when the medium is fed along the feeding path, wherein, in a cross section perpendicular to a direction in which said medium is fed along said feeding path, a tip of each rib comprises: an end portion that guides said medium; and an inclined portion provided on only one side of said end portion in the widthwise direction of said rib, said inclined portion extending from said end portion to one of said sidewalls so that said medium contacts the end portion of the rib and not the inclined portion, a projection being located on said inclined portion, a top surface of said projection being located below said end portion of said rib.
