Information recorder in form of signs on light sensitive material - uses light beam reflected from mirror and galvanometer controlled by sign forming unit

摘要

The rotation axis of the mirror of the 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 the mirror along the surface of the 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.
