ABSTRACT:
A rotatable "Y" scan mirror for a flat field scanning system is provided whereby the mirror is shifted in opposite directions transverse to its pivotable axis and is simultaneously rotated in one direction during a scanning cycle. A pair of cams is mounted on a common rotatable shaft for rotation therewith. One of the cams actuates a link connected to a pivot pin on which the mirror rotates. The other cam actuates an arm which is connected to the mirror to rotate the same. The cams are so designed to cause shifting of the mirror to maintain a constant length optical path to the medium being scanned and to cause rotation of the mirror in such a manner that the rate of scanning across the medium will be constant.
