Abstract
A document reproduction system is disclosed which employs an imaging array assembly positioned to transmit reflected images from a document in an object plane onto an imaging plane. The imaging assembly includes a 1X lens array and at least one reduction/enlargement lens array. The overall dimensions of the total imaging area of the reproduction system are reduced from conventional fixed lens or fixed document system by providing means for moving the document, imaging assembly and imaging plane in certain prescribed relationships. These means include a pulley/cable/clutch arrangement which enables changes in velocity relationships which are required for a unity magnification mode of operation as well as those for a reduction or enlargement modes of operation.
