The beam of a line scan fiber optics cathode ray tube is repeatedly swept along the phosphor element of the tube by a horizontal deflection coil to provide traces, representing the values of a plurality of data signals, which are recorded on a record sheet drawn continuously over the face of the fiber optics strip of the tube. A vertical shift deflection coil, energized by the trianglular wave output signal of a shift deflection generator, slowly and continuously shifts the path, along which the beam sweeps on the phosphor, up and down between the boundaries of the area of the phosphor which is coextensive with the active area of the fiber optics strip.
