Abstract:
An automatic paper feeding system comprising:a housing; a paper tray installed within the housing for holding paper, a front end of the paper tray being able to move up and down; a paper-feeding channel located in front of the front end of the paper tray; a paper-grabbing device installed on the paper tray for moving paper in the paper tray into the paper-feeding channel; a paper-separating device comprising a paper-separating roller and a paper-separating friction disk respectively installed above and below the paper-feeding channel; wherein when two sheets of paper are moved to a contact point between the paper-separating roller and the paper-separating friction disk, the paper closer to the paper-separating roller is moved forward by the paper-separating roller, and the paper closer to the paper-separating friction disk is stopped by the paper-separating friction disk; an actuator mechanism installed under the paper-feeding channel for simultaneously lifting up or pulling down the front end of the paper tray and the paper-separating friction disk; and a driving device for simultaneously driving the paper-grabbing device, the paper-separating device and the actuator mechanism; wherein when the driving device is activated, the actuator mechanism is driven to lift up the front end of the paper tray and the paper-separating friction disk, and when the front end of the paper tray is lifted up, the 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, and the paper-separating friction disk upwardly contacts the paper-separating roller so that the paper-separating roller continues to move the paper along the paper-feeding channel.
