Abstract
A document photography system photographs the obverse and reverse faces of a moving document by tracking the document with a moving lens. The motion of the lens is in timed relation to the velocity of the document and in dimensional relation to the reduction of the lens. The lens is supported in a flexural mounting which allows the lens to be displaced upon the application of motive power. Motive power is provided by a rotational motor which has its output translated to rectilinear motion by mechanical linkage. The motor output is fed back by an optical tachometer to a phase-locked servo system to maintain uniform, linear lens motion.
