ABSTRACT:
An apparatus for discriminating a printed matter having a discriminating pattern printed thereon, including: a sensor for scanning the printed matter and producing an analog signal corresponding to the discriminating pattern thereof. A timing device is provided for generating periodical timing signals in proportion to the transferring speed of the printed matter. An analog-digital converting device is provided for sampling the analog signal in accordance with the timing signals, and producing a series of digital sampled data. A reference data memorizing device is stored therein with at least one reference to be compared with the series of sampled data, and a control system which shifts each reference data in address a plurality of times relative to the series of sampled data, checking if the amplitudes shown by the sampled data are within the allowable limits shown by the the reference data, and determining from the results of the checks the coincidence or noncoincidence between the series of sampled data and the reference.
