Abstract

The figure shows an optical system for projecting an image of a document 2 moving through an exposure zone, onto a flat photoreceptor belt 4. A fixed lens 6 combines with a translatable mirror 8 and a pivoting mirror 10, with both mirrors positioned on the image side of the lens. The lens and two mirrors are movable as a unit towards and away from the photoreceptor to enable a reduction or enlargement conjugate change. Mirror 8 translates along a path dependent on the system geometry, mirror 10 rotates in synchronism so as to reflect the projected image onto the photoreceptor in a direction opposite to that of the belt direction thereby precessing the image and gaining some relaxation time during rescan.
