ABSTRACT:
A method for an automatic document feeder which can control the feeding of a following sheet such that the following sheet can be delayed for a predetermined time when the interval between sheets is shortened, thereby maintaining a constant interval between the sheets. The method and apparatus comprises a paper feeding roller, an arranging roller for arranging a front end of a document being fed by the paper feeding roller and for transferring the document, and an arranging sensor disposed at a front portion of the arranging roller to detect whether the document is being transferred. The arranging sensor detects a rear end of a previous sheet and a front end of a next sheet, and an operation of the arranging roller is controlled using a time interval between the previous sheet and the next sheet.
