Abstract (en)
A device for recognising and examining bank-notes (20) or the like, in which a bank note is transported through a transverse light curtain, and the transmission fluctuations caused by the printed patterns are detected by means of a row of light-sensitive cells, (10) the output signals thereof being stored in a matrix buffer memory (30) as a digital picture of the bank-note, said picture being compared with corresponding data relating to a reference banknote of the same value permanently stored in one of a plurality of partial memories, (36a..d), the comparison results of at least a substantial part of the bank-note being statistically processed, all this irrespective of the orientation of the bank-note. Moreover the dimensions, colour and ultra-violet remission of the bank note are determined, at least one of the first two measurements being suitable for determining the value of the bank-note. Since the picture of the bank-note is temporarily held in the buffer memory (30), a repeated comparison is possible, in particular in respect of different orientations of the bank-note. In particular the partial memories contain only a sample relating to discrete parts arbitrarily distributed over at least a substantial part of the reference bank-note.
