ABSTRACT:
A roller apparatus for an automatic paper-feeding mechanism has two parallel swing rods. The two swing rods are biased upwards by an elastic component. An upper roller is rotatably disposed at an end between the two swing rods. A paper-in roller is rotatably disposed at another end between the two swing rods. A first gear is disposed on a shaft of the upper roller. A second gear is disposed on a shaft of the paper-in roller. A first idle wheel rotatably 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 shaft of the first idle wheel. The second idle wheel engages a central gear rotatably disposed on the shaft of the upper roller.
