An automatic paper-feeding mechanism has two parallel swing rods. The two swing rods are restricted upwards by an elastic component. An upper roller is pivotally disposed at an end between the two swing rods. A paper-in roller is pivotally disposed at the other end between the two swing rods. A first gear is disposed on a pivot of the upper roller. A second gear is disposed on a pivot of the paper-in roller. A first idle wheel pivotally disposed on one of the two swing rods is engaged between the first gear and the second gear. A second idle wheel differentially matched with the first idle wheel is disposed on a pivot of the first idle wheel. The second idle wheel engages a central gear pivotally disposed on the pivot of the upper roller.
