Abstract

System for reading information, which comprises, in combination, a carrier of information that includes a base and information indications supported by the database and with physical properties that differ from those of the database; a detector that detects the physical properties of the information indications when the information carrier passes through the detector, the information indications being arranged in the base so that during a reading operation each indication of information is detected twice by the detector; a first impulse generator element connected to the detector output and during each reading operation provides a succession of output pulses comprising first output pulses corresponding only to the detected information indications having certain physical properties, each one whose first impulses appear twice in the succession of output impulses; a second impulse success generating element connected to the output of the detector and during each reading operation provides a succession of output pulses comprising clock pulses corresponding to each of the information indications detected; elements that respond to the impulses in the same number as the indications of information and related each one of them with a different information indication, connected to the outputs of the two impulse-generating elements, and operable in response to a first impulse and a clock pulse on its output, to provide a control output signal; and displacement signal elements connected to the output of different elements that respond to pulses, and operable upon receiving, during each reading operation, the two control output pulses at its input to provide a displacement signal at its output.
