Abstract
Three elongate, circular rods are secured to the inner peripheral surface of a lens barrel to extend axially thereof and in angularly spaced relation to each other. Each of two cylindrically shaped lens housings is mounted coaxially in the barrel for axial adjustment therein by means of three sets of rollers, each of which sets is mounted on the housing to have rolling, point engagement with a different one of the rails. At least one set of rollers on each housing is urged resiliently into rolling engagement with the associated rail, and each housing is connected to one of two camming rings which is rotatably mounted on the barrel to effect axial adjustment of the housings.
