Abstract: The proposed device for recording information in the form of signs of a light-sensitive material by means of a light beam comprises a galvanometer. The rotation axis of the mirror of said galvanometer is parallel to the direction of movement of the light-sensitive material whereon information is recorded in the form of signs by means of a light beam reflected from the mirror and shifted by said mirror along the surface of said light-sensitive material. The galvanometer is controlled by a sign-forming unit which is a quantized lever circuit whose output is electrically coupled to the galvanometer, whereas its inputs are connected to outputs of a logical matrix. Entered into the information inputs of the matrix is decimal-coded information corresponding to a sign to be represented and read out by means of pulses arriving from a pulse distributor connected to the readout inputs of the matrix and controlled by a reference frequency generator. The design of the proposed device ensures a sign recording rate of 200 to 300 signs per second.
