Abstract
A combiner is pivotally mounted for movement between an operating position in the line of sight of an operator and a storage position. A sector gear fixed to the combiner engages a slidable rack so that sliding the rack causes pivotal movement of the combiner. A control knob and stem are mounted for rotary movement and translation. A cam rotated by the knob engages followers on the rack to slide the rack upon knob translation or rotation. Knob translation effects movement of the combiner between operating and storage position, and when in operating position, knob rotation effects fine adjustment of the combiner to adjust image position.
