ABSTRACT:
An image forming machine driving apparatus includes a first one direction power transfer part transferring or cutting off a dynamic power of a driving motor to or from a feeding part according to rotation directions of the driving motor, and a feeding part power-engaging removal device cutting off a jammed paper-removing force not to be transferred to the driving motor when the jammed paper-removing force is applied to the feeding part in a power transfer direction of the first one direction power transfer part, thereby preventing the jammed paper from being torn off or damaged when the paper jammed in the feeding part is removed during supplying or feeding the paper. The image forming machine driving apparatus cuts off the transfer of the jammed paper-removing force not to be transferred to the driving motor by the first one direction power transfer part and the feeding part power-engaging removal device regardless of paper-removing directions when a user removes the jammed paper occurring in the feeding part during supplying and feeding the paper, thereby preventing the jammed sheet of paper from being torn off or damaged.
