Abstract

A double-side automatic feeding apparatus comprises a paper feeder, a paper outlet opposite to the paper feeder, a scanning region having a document traveling path bridging the paper feeder and the paper outlet, a plurality of rollers being arranged in the scanning region to convey a document to be scanned from the paper feeder to the paper outlet, and a paper flipping unit arranged in the document traveling path. The paper flipping unit can be selectively switched position thereof and used to flip the document during the document traveling path. By the invention, the document can be scanned on both sides thereof without cumbersome reverse movement. The document can be automatically aligned by the weight per se and the operations of paper placement and removal can be simplified.
