Abstract
An improved recirculating document feeder for presenting sheets from a document sheet stack individually to a station of the reproduction apparatus for reproducing of information contained on such sheets. The improved recirculating document feeder comprises a support for a document sheet stack. A feed path extends away from and then back to the document stack support, for directing sheets from the support into association with the reproducing station and then back to the stack. Document sheets are fed from the stack seriatim about the feed path. An array of sensors is provided with individual sensors of the array respectively positioned at predetermined locations about the feed path for detecting a document sheet at the predetermined locations as said document sheet is fed. The individual sensors respectively produce signals when detecting a document sheet. In responsive to the signals from the array of sensors, operation of a subsequent portion of the document sheet feeding mechanism is sequentially effected based on a signal from the sensor at a preceding detected document sheet location.
