Abstract
A paper-feeding mechanism for a document duplicating machine, which is driven by a single power source and performs intermittent paper-loading control and continuous paper-conveying operation on a paper loader of the document duplicating machine, comprises a driving device capable of both clockwise and counterclockwise running operation, a paper-loading device for carrying out the intermittent paper sheet retrieval from the paper loader, a paper-conveying device for performing forwarding of the paper sheet retrieved from the paper loader, and a paper-conveying-and-loading control device for separating the paper-conveying and paper-loading operation of the paper-feeding mechanism.
