Abstract

An automatic paper feeding system has a paper-grabbing device and paper-separating device, with a paper tray having a front end that can move up and down. A paper-feeding channel is in front of the front end of the paper tray. The paper-grabbing device is installed on the paper tray and moves paper in the paper tray into the paper-feeding channel. The paper-separating device has a paper-separating roller and a paper-separating friction disk which are respectively installed above and below the paper-feeding channel. These elements together permit only a single sheet of paper to move forward. An actuator mechanism installed under the paper-feeding channel lifts up or pulls down the front end of the paper tray and the paper-separating friction disk. Finally, a driving device drives the paper-grabbing device, the paper-separating device and the actuator mechanism. When the driving device is activated, the actuator mechanism lifts up both the front end of the paper tray and the paper-separating friction disk, and paper placed in the paper tray comes into contact with the paper-grabbing device. The paper-grabbing device moves the paper into the paper-feeding channel. The paper-separating…
