- 1 - ABSTRACT A raster input scanner incorporating a scanning array, a platen for supporting documents to be scanned, a lens, and an illuminator. The lens is supported for micro movement in close proximity to the array, such movement being imparted by a linear motor. In one embodiment, the illuminator comprises a stationary light source with oscillating mirror for sweeping a wedge-like beam of light across the platen in synchronism with movement of the lens to progressively illuminate the document being scanned. A park position is provided for the lens and illuminator and a document feeder provided to transport the document to be scanned across a scan slit provided in the platen in an alternate operating mode. In a second embodiment, the illuminator comprises a lamp cavity reciprocable along a path parallel to the platen to progressively illuminate theplaten.
