Abstract
A lens carriage is mounted upon a cylindrical way at a left-hand portion thereof, and is supported at a right-hand portion thereof by a single roller which rolls over a flat plate way during translation of the carriage parallel to the optical axis of the phototypesetter. A brake shoe coupled to the carriage is spring biased against the lower surface of the flat plate way, and as a result, there is no play or looseness in the arrangement and yet imprecise positioning of the way elements in space, to save manufacturing costs, results in modest and repeatable shifts of the lens element mounted upon the carriage in directions transverse to the optical axis.
