ABSTRACT:
A document feeder for broad-width originals having a document path in which a moving document is scanned by a stationary scanner. The document feeder is typically mounted to a copier. The document path is either a recycling path or a reciprocating path; the recycling path having a closed loop path and the reciprocating path having an open loop path. A selector is mounted in the document path and selects one of the recycling path and the reciprocating path. A sensor is mounted in the document path for detecting a length of the document. When the length of the document detected by the sensor is not longer than a predetermined length, the recycling path is selected by the selector. When the length of the document detected by the sensor is longer than the predetermined length, the reciprocating path is selected by the selector.
