Abstract

A paper feeder includes a base, a roller adjacent to the base, a holder for holding a paper, and a torsional element. The holder has a pivot end and a movable end, wherein the pivot end is pivoted to the base. The torsional element is disposed at a position where the holder is pivoted to the base, and provides torsion to move the movable end of the holder to be pressed against the roller, such that a front edge of the paper is raised to be in contact with the roller. As the roller rotates, the paper is fed into a paper feed track by a frictional force.
