Conventionally, in a moving platen copier, the glass platen reciprocates, carrying on it a document that was previously manually placed on the platen. The platen and the document thereon are reciprocated relative to a fixed imaging station (slit).

Here, an automatic document feeder is provided for such a moving platen copier wherein the placement of the automatic document feeder (ADF) over the platen automatically, mechanically, or electrically disengages the normal drive of the platen and locks the platen. The normally moving platen is automatically locked in a stationary position by the ADF so as not to interfere with the automatic feeding of the documents thereover. Thus, this document handler may be utilized to stream-feed documents from a stack of documents placed therein over the imaging station at the speed of the processor (as in the Xerox Corporation "3100 LDC"
fixed-platen copier). When the automatic document feeder is removed the copier is automatically restored to its normal moving platen mode of operation.
