1. Apparatus for driving a continuous strip linearly and rotatively, comprising:

  • a housing having an opening;

    a platform movably set within the housing;

    a strip driving means fixedly mounted to the platform, the driving means including;

    (a) a first support plate;

    (b) a second support plate;

    (c) a third plate having an aperture concentrically aligned with the opening interposed transversely between the first and second plates;

    (d) means for holding and guiding the strip movably mated to the first and second plates, a portion of the strip being superimposed on the aperture;

    (e) bi-directional positioning means engaged to the holding and guiding means for translating the strip to a particular frame across the aperture;

    first actuating means secured to the housing for driving the bi-directional positioning means, thereby moving the strip across the aperture;

    second actuating means secured to the housing for rotatably moving the platform, thereby rotating the strip;

    whereby the strip is translated and rotated for correlating symbols on each frame of the film at any orientation with predefined symbols.
