Abstract
A media feeding mechanism mainly comprises a base provided with a first surface and a second surface, a first roller, a second roller, a first one-way bearing used to support the first roller, a second one-way bearing used to support the second roller, a cam gear and a stopper. To prevent media from wrinkling or skewing, the media transmitted by the first roller is deskewed by contacting with the idled second roller for a predetermined period of time. The first roller 11 is idled when the deskewing process concludes. Rotation of the second roller clockwise scrubs the media toward the exit point.
