Abstract: An ADF (Automatic Document Feeder) for an image processing apparatus of the present invention includes a separating and feeding device for feeding one document from a stack of documents while separating the document from the others. A conveying device temporarily stops the document fed by the separating and feeding device at a position preceding a reading position and again conveys, on the elapse of a preselected period of time, the document toward the reading position. A controller controllably drives the separating and feeding device and conveying device. The controller drives the conveying device by controlling the time interval between the restart of conveyance of the preceding document and the restart of conveyance of the following document.
