Abstract

Gradient index lens arrays have found wide usage in compact copiers by virtue of their relatively short (40-1 OOmm) conjugate requirements. The more conventional systems maintain the lens array in a fixed position and move the document through an exposure zone generally by means of a movable platen. If the platen is held stationary and the lens array moved, the velocity ratios between the lens array and the moving image recording sheet (photoreceptor) must be determined. In particular, when more than one lens array representing more than one magnifi-cation value is utilized, the precise ratio to be determined becomes more complex.
