Abstract
A feeder roller apparatus for high speed image scanning equipment, which improves feeding of documents, and in particular short documents, sequentially fed from a stack. The feeder apparatus comprises a PIC roller and an infeed roller which are selectively, independently driven via a dual drive shaft, composed of an inner drive shaft and an outer drive shaft, driven together or selectively, independently by a main motor. An electro-mechanical clutch, when energized is used to drive the PIC roller. A sensor is provided downstream of the rollers to recognize when a document is being fed. Initially, the clutch is energized, and both rollers are driven. When the first sheet reaches the sensor, the clutch is de-energized, cutting off the drive to the PIC roller. The main motor continues driving only the infeed roller until the first sheet is fed.
