    摘要： A data recorder including a plurality of coaxial settable print wheels nested in closely spaced printing relation, and rotary gear trains for positioning the print wheels under control of selectively operable indexing wheels spaced only a short distance from the print wheels. Extension gears are provided for laterally spreading out the rotary gear train from the closely positioned print wheels to the indexing wheels, thereby spreading apart adjacent indexing wheels sufficiently to allow for operator finger contact with the indexing wheels individually to permit independent movement thereof.
