Electrical instructions generators by manual interruption of a light beam

Abstract

Abstract Generator of the type comprising a series of radiation sources, a series of detectors of this same radiation, as well as a power and end-use circuit (3) attached to the sources and to the detectors, characterised in that the sources and the detectors are arranged respectively along parallel rows facing one another and forming a series of source/detector pairs intended to be combined respectively with visual indicators (H,B,D,G,Z,N) for making visible an instruction to be given, and in that there are further provided in the power and control circuit (3) means which, when a radiation beam of a source/detector pair is interrupted, generate an electrical signal able to trigger the instruction corresponding to this beam. <IMAGE>
