Abstract
A microfiche is titled by synchronously and incrementally imaging title information having a rotary motion upon the film carrying the microfiche that has a linear motion. Selectable drums carry the title information. Image-forming means transfers this information for the exposure of microfiche film. Equivalent motor means drive both the drum and the microfiche film. Electronic control logic connected to both of the motors accomplishes synchronous motion so that the title information is fixedly impressed with respect to the microfiche film despite the fact that both are in motion.
