ABSTRACT:
A paper feeder disposed on a casing for feeding a paper is provided. The paper feeder includes a feeding axle and a paper stopper. The feeding axle has a first engaging portion. The paper stopper includes a blocking plate and a second engaging portion. The paper stopper is co-axially and rotatably disposed on the feeding axle. When the feeding axle rotates in a first direction to engage the second engaging portion with the first engaging portion, the feeding axle drives the paper stopper to rotate in the first direction until the blocking plate blocks the paper. When the feeding axle rotates in a second direction to detach the second engaging portion from the first engaging portion, the feeding axle is able to feed a paper.
