Claims

[Scope of utility model registration request]

In an automatic paper feed drive mechanism for a facsimile or other similar device, which includes a separation roller that separates and moves stacked documents, a foot roller that runs and moves the separated documents, and a reversible drive motor that drives the separation roller and the feed roller. , the separation roller is provided with a separation roller transmission mechanism that transmits a driving force to the roller in only one direction, and the feed roller transmits a driving force in only one direction to two sets of mutually inverted drive systems and the feed roller. A feed roller transmission mechanism is provided, and by reversing the reversible drive motor during and after document separation, the separation roller and the feed roller are rotated in cooperation with the transmission mechanism during separation, and the separation roller is rotated after separation. An automatic paper feed drive mechanism characterized in that the feed roller is rotated while the feed roller is stopped.
