Abstract
A dual mode image input terminal having a linear scanning array with optical and illumination means supported on a carriage that, in a first scanning mode, reciprocates from a start-of-scan position to an end-of-scan position to scan a document opposite thereto on a transparent platen, and, in a second scanning mode, assumes a predetermined fixed scan position adjacent one side of the platen, with a Constant Velocity Transport (CVT) type document transport for moving the document past the fixed scan position with the document in preset spaced relation above and out of contact with the platen to avoid wear on the platen and allow room for document assisting devices ancillary to the CVT, and with the inside surface of the platen at the fixed scan position only being thicker than the remainder of the platen to raise the image focus point of the scanning array from the surface of the platen to the level of the document transported past the fixed scan position by the CVT.
