Abstract
Abstract Apparatus for linearly adjusting the position of devices, and in particular, apparatus for adjusting focus of an image on a light sensitive surface of an image sensor device included in an optical character recognition read head. The apparatus includes a first mechanism for adjustably positioning a lens assembly for adjusting focus at the image plane, and a second device for adjustably supporting the image sensor device for adjusting the position of its light sensitive surface to coincide with the plane of the focused image.
