Abstract

The invention relates to a device for scanning the division mark of a mechanical roller-type counter (1), for any type of counter, comprising a number of rotatably driven ciphering rollers (2), each ciphering roller carrying a number of digits (3) or symbols that are distributed homogeneously over the circumference and can be detected and evaluated with a fixed reading device arranged opposite. Said device is characterized in that at least one transponder (6) is associated with each digit (3) or each symbol in the respective ciphering roller (2) of the roller-type counter (1). An RFID antenna field (15) is located opposite the transponder, at a small distance therefrom, said field being controlled by a circuit in such a way that a ciphering roller of the roller-type counter (1) can be read respectively by an antenna (16, 17, 18) of the RFID antenna field (15).
