Document feeder electronic registration gate

Image Number 6 for United States Patent #4455018.

A sheet registration apparatus for positioning sheets in a registered position on a work surface such as the document platen of a convenience copier/duplicator machine. The apparatus includes a bidirectional servo-controlled sheet transport for conveying the sheet over the work surface. A sheet sensing device is disposed within the path of sheet travel. A controller monitors the sensing device and activates a position control routine following the occurrence of a predetermined level change in the signal generated by the sensing device. At the end of the position control routine, the transport is stopped thereby positioning the sheet in the registration zone. The apparatus enables sheet registration for a machine operating in a duplex and/or simplex mode. The apparatus further enables registration at any point on the document platen.
