  • the guide runners 13 are advantageously arranged above and below the transport plane 15 and on both sides of the passage 17 for the exact guidance of the bank note 10 in order to prevent the bank note 10 from queuing at the passage 17 which is not quite flat.
  • At least one pair of the same transport units 18 and 18 ' is advantageously arranged parallel to these.
  • the number of these parallel transport units 18 and 18 ' is predetermined by the largest predetermined width of the banknotes 10 to be transported without being damaged by the measuring system.
  • the distances of the light source 6, the diffuser 7, the catcher 4 and the detectors 5 from the transport plane 15 depend on the optical properties of the means used for the elements 4, 6 to 9.

  • the diaphragm is, for example, part of the passage 17.
  • the extent of the read-out light beam 14 is only a few millimeters, advantageously less than 5 mm.
  • the reading light beam 14 passes through the scanning plane 15 ′ in the passage 17 and illuminates a rectangular reading field 20 of the bank note 10 located in the passage 17.
  • the bank note 10 is pushed in the transport direction 16 by the reading light beam 14, the read-out field 20 gradually covering the entire area of the bank note 10.
  • the evaluation device 2 assigns the reading field 20 a value X of a reading direction 16 ', which is opposite to the transport direction 16.
  • a filter 24 with a predetermined spectral transmission characteristic is advantageously arranged so that each detector 5 or 5' has a sensitivity to light 19 ', the spectral range is limited by the filter 24 .
  • the optical design of the banknotes 10 of the predetermined set of nominal values determines the required number of detectors 5 to 5 'and the suitable pass characteristic of the filter 24.
  • An advantageous embodiment of the banknote reader 1 has four different spectral ranges. For example, they are in the area of blue, yellow-green, red and infrared light.
  • the signal E has a reference level E0 which is separate for each spectral range.
  • the usual bank notes 10 (FIGS. 2 and 3) of each denomination consist of a predetermined paper and have a printed, predetermined pattern on both sides.
  • the light 19 urgent in the read-out field 20 through the bank note 10 ' is changed and weakened in a predetermined manner in the spectral distribution by the transparency of the paper and the pattern and by the possible security thread.
  • During the passage of the banknote 10 through the passage 17 thus change the intensity and the spectrum of the light 19 ', which penetrates the banknote 10, in a predetermined function of the values X in the reading direction 16', which characterizes each denomination of the banknote 10.
  • the transparency of the banknote 10 is averaged over the entire read-out field 20, since only a single signal E is generated for each predetermined spectral range.
  • the computing unit 3 takes over the instantaneous value of the signal E at each step of the transport system and forms only a single measured value of the transparency for each of the predetermined spectral ranges for the entire readout field 20.
  • the computing unit 3 'advantageously normalizes all measured values of transparency before saving to the reference level E0 of the corresponding spectral range in order to eliminate the influences of the light source 6 which depend on the operating time and the sensitivity of the detectors 5, 5'.
  • the measured values are stored together with the value X of the reading direction 16 'in the memory 3.
  • the banknote reader 1 described has the advantage that the same measured values are stored in the same order, irrespective of whether the front or the back faces the catcher 4 if only the scanning starts at a predetermined edge of the banknote 10.
  • the height of the signal E falls markedly from the reference level E0 when the banknote 10 enters the read-out light beam 14.
  • the banknote 10 covers the path through the passage 17 in, for example, N steps, the N readout fields 20 successively covering the banknote 10 area-wide.
  • N measured values with the assigned values X0 to X N are stored in the memory 3.
  • the value of the difference X N -X0 is proportional to the length of the banknote 10, the values X0 to X N advantageously being evenly distributed in the reading direction 16 '.
  • the transverse dimension of the banknote 10 is at most equal to or smaller than B, depending on the transverse dimension of the banknote 10, in addition to the light 19 changed by the banknote 10, a predetermined one also arrives Proportion of unchanged light 19 of the read-out light beam 14 in the collector 4.
  • the drop in the signal E thus depends not only on the transparency of the banknote 10, but also on the width of the banknote 10, the decrease in intensity and the decrease for narrow banknotes 10 Change in the spectral composition of the light 19 'is less pronounced than for broad ones.
  • the exact position of the banknote 10 in the passage 17 does not influence the signal E, so there is advantageously no need for a device for the precise lateral guidance of the banknote 10 in the passage 17.
  • the banknote reader 1 compares the measured values of the transparency of a banknote 10 to be identified with sample values of a predetermined set of nominal values, which are stored in the memory 3. To determine the length of the banknote 10, the arithmetic unit 3 '(FIGS. 1 and 2) examines whether the number N of measured values corresponds to the number of sample values for each nominal value of the predetermined set. If the banknote 10 has the same length as one from the predetermined set of nominal values, then for each predetermined spectral range in the evaluation device 2, the difference between the measured value of transparency standardized to the reference level E0 and the correspondingly standardized sample value is known for each value X. of this nominal value.
  • a correlation value is calculated from the N differences for each of the predetermined spectral ranges and compared with a predetermined limit value.
  • the banknote 10 is only recognized as this nominal value if the correlation values are above their limit values. If this condition is not met, the bank note 10 is rejected as unidentifiable.
  • the bank note 10 is assigned the nominal value whose sample values have the best correlation to the measured values of transparency.
  • the predetermined set of the sample values can be generated by reading banknotes 10 from a predetermined set of the predetermined nominal values by means of the banknote reader 1 even during commissioning or during a revision. It is also possible to transfer the sample values stored in the memory 3 from a first banknote reader 1 to another of the same design.
  • the measured values of the transparency of a bank note 10 recognized as genuine are advantageously used to modify the sample values of this nominal value.
  • the banknote reader 1 thus adapts to the small differences between the different series of the same face value and reduces the number of rejected real banknotes 10.
  • the evaluation device 2 advantageously generates a digital output signal at an output 25, for example corresponding to a number assigned to the nominal value of the recognized bank note 10 in a predetermined manner, or has a predetermined error code if the evaluation device 2 classifies the bank note 10 as unidentifiable. .
  • the computing unit 3 also advantageously compares the N measured values, which are called up in the reverse order X N ... X N from the memory 3, for each spectral range with the N sample values of the order X0 ... X N.
  • the banknote reader 1 recognizes banknotes 10 independently of one of the four possible positions in the passage 17, wherein a mechanical turning device in front of the banknote reader 1 is advantageously unnecessary.
  • a banknote 10 of, for example, 20 cm in length is read across the entire surface in 50 steps by means of a banknote reader 1, which measures simultaneously in four spectral ranges, with a width of the readout beam 14 of 4 mm measured in the readout direction 16 ', the evaluation device 2 from the signals E the four detectors 5 to 5 'each generate 50 measured values in four spectral ranges, d. H.
  • the entire banknote 10 is characterized by only 200 measured values. This is advantageous when recognizing the banknote 10 from a large number of predetermined nominal values and enables a rapid recognition process.
  • a continuous feed is also advantageous, with the bank note 10 moving at a uniform speed throughout the transport system, so that the bank note 10 is largely protected.
  • a means which is not shown here and is known per se generates a synchronization signal which is fed in the evaluation device 2 to a counter (not shown here).
  • the synchronization signals are staggered in time in such a way that a synchronization signal always then appears when the banknote 10 has shifted by the width of the read-out field 20.
  • the counter is switched off and set to the counter reading zero.
  • the counter is switched on and the counter reading increased by one after each synchronization signal from the memory 3.
  • the counter reading serves as the value X, which numbers the readout fields 20 or the measured values of the transparency in the order of scanning.
  • the measured transparency values of the readout fields 20 lined up across the banknote 10 are sufficient. It is even possible that the measured values of the transparency are determined and stored only for every second step, for example. Depending on the type of printed pattern of a banknote 10, this reduced set of measured values is sufficient for an identification of the banknote 10 or its orientation in the banknote reader 1.
  • the diffuser 7 and the cylindrical lens 8 are advantageously replaced by light guides 26 (FIG. 4), by means of which the light 19 is guided from the light source 6 to the scanning plane 15 '.

  • the catcher 4 (FIG. 6) has at least the same dimension in the transport direction 16 as the read-out light beam 14 on the entry side 21.
  • the catcher 4 consists of a plate made of light guide material, for example of a transparent plastic or a glass, and advantageously has a trapezoidal shape or the shape of a flat, non-hollow funnel with a rectangular cross section, which tapers towards the connecting piece 22 transversely to the transport direction 16.
  • an astigmatic imaging system above the scanning plane 15 ' can also be used, in the focal line of which at least one filter 24 and one detector 5 are arranged and whose opening cross section has at least the dimensions of the entry side 21. All light 19 'that penetrates the entry side 21 is collected in the catcher 4 in the focal line of the imaging system.
  • the catcher 4 consists of a light guide plate, the edges of which have a flat edge surface on the entry side 21 and a parabolic curved edge surface 30.
  • the connector 22 is embedded, which encloses the focal line of the edge surface 30 and which guides the light 19 'to the filter 24 and detector 5.
