An automatic paper feeder for an image-scanning device with a pressure-adjustable mechanism for adjusting the paper feeding roller of the automatic paper feeder is disclosed. A pressure from paper sheets stacked on a paper tray of the automatic paper feeder is detected by a paper tray pressure detecting mechanism and transferred to a roller pressure adjusting mechanism to change a pressure between the paper feeding roller and a paper separating plate and adjust a feeding angle of the movable paper tray.
