Device for detecting coding regions particularly for reading forms in general, which comprises photocells for detecting a sheet-like element provided with a plurality of predefined coding regions, a motor and roller for moving the sheet-like element which can be selectively activated and deactivated by the photocells, a magnet for activating the predefined coding regions, at least one pair of read heads for detecting the predefined coding regions and for generating a read signal, a converter for each reading head, for converting the read signal into an analysis signal, and finally an analog/digital converter for transferring the analysis signal which arrives from each converter to a microcomputer which generates a synchronization signal which can be transmitted to the converter. <IMAGE> |
