US 6,199,853 B1 · Document handler with a staple mode and a moveable stopper

Abstract

An automatic document feeder which is operable in each of a sort/stack mode, an inversion mode, and a staple mode. A tray is provided on which a document to be stapled is stacked. A positioning element and a driving roller are provided for directing the document to be stapled to the tray and for properly positioning the document on the tray. A movable stopper is formed on the tray for properly positioning the document at a stacking position, a stapling position, and a discharge position. The document can be stapled at either a single place or at multiple places. The document passes through a first document path in the sort/staple mode, and passes through a second document path in a staple mode. The document also passes through a portion of the second document path in the inversion mode.
