The Geneva Drive translates continuous rotary motion into regular intermittent motion. If the driven wheel has four fingers, it turns 1/4 turn for each full rotation of the drive wheel. (If the driven wheel has x fingers, it turns 1/x turn for each full turn of the drive wheel.) In addition, the driven wheel is locked in position between movements.
Movie cameras and projectors use Geneva Drive mechanisms to advance the film.
