ABSTRACT:
A jam removing apparatus of a machine having an ADF function to effectively remove a sheet of paper jammed between an ADF roller and a feed roller includes a middle gear engaged with a gear train engaged with an ADF gear of the ADF roller and having a unit to transfer only one-way rotation, a feeding gear engaged with the middle gear and coaxially connected with the feed roller to transfer the paper, and a jam removing unit connected with a shaft of the feeding gear to rotate the feeding gear when removing the jammed paper. The jammed paper is transferred only in a paper supplying direction but not in an opposite direction of the paper supplying direction, thus the jammed paper can be prevented from being damaged by being crumpled by the ADF roller.
