Abstract
Abstract An improvement in a fiber optic illuminating system having a linear array of fiber ends and a platen for supporting an original document to be scanned and copied. The improvement includes a flexible lens assembly situated intermediate the array of fiber ends and the platen, a deflectable frame supporting the flexible lens assembly, and a device for deflecting the deflectable frame, whereby the flexible lens assembly can be transversely deflected to thereby modify the linearity of the lens assembly without disturbing the focal adjustment thereof.
