Definitions

  • the invention relates to a device for checking securities, in particular Banknotes comprising a transport device for conveying the securities along of a transport path and a detection device arranged on the transport path.
  • the automatic detection of banknotes and other securities is both in the Bank area as well as for example at the point of sale an important concern.
  • the construction the hardware is not unimportant for the smooth transport of the banknotes and the quality of the reading process. It should enable a high processing speed.
  • the precision and performance of the hardware often leads to high costs of the device, which can significantly reduce the market opportunities.
  • From US 5,607,040 is a device for checking the authenticity of individual banknotes known at the point of sale. It is with two optical lenses directly opposite each other Scanners equipped to scan the front and back of the banknote. Before and after Rollers are provided for the scanners to transport the banknotes. The rod-shaped Optical scanners are used to digitize and detect those printed on the note Numbers trained. The notes are transported and processed in the longitudinal direction.
  • Rod-shaped optical scanners are e.g. known from US 5,489,992, US 5,214,273 and available on the market.
  • a note recognition device in which the Banknote to be checked for value and authenticity with a light source which covers at least two different wavelength ranges.
  • the reflected light will detected with two different sensors (green light and red light sensor) and line by line registered.
  • a difference signal is determined and with a predefined one Pattern compared.
  • the known devices are not capable in mechanical / electronic terms to satisfy.
  • the object of the invention is to provide a device of the type mentioned in the introduction, which has powerful yet relatively inexpensive hardware. Especially a high level of security of detection at high transport speed be made possible.
  • the detection device comprises two integrated ones arranged side by side optical modules for scanning the securities in two different wavelength ranges.
  • Each module is a mechanically closed unit and generates and processes the each prescribed wavelength range independently.
  • the optical components can therefore be optimally adjusted to the respective spectral range.
  • the device according to the invention can be manufactured using prefabricated components take place, which has a prescribed (geometric / mechanical) precision. When assembling, it is sufficient to pay attention to the exact positioning of the modules.
  • the modules are included parallel longitudinal axes, but mounted to each other with slightly tilted front panels.
  • the So modules both scan the same side of the security, with the sensing housing surfaces - as mentioned - are slightly tilted towards each other. It should be noted that this Aspect of the invention regardless of whether the modules have different wavelength ranges process or not.
  • the scanning housing surfaces are, for example, at an angle greater than 0 ° to one another tilted. If the angle is too small, the location of the line of contact between the banknote and the rear front panel are not specified exactly enough. Is the angle against it too large, then the front panel mentioned acts as an obstacle instead of a distraction.
  • the front panels meet at the edges (or with the adjoining side walls) to each other and thereby enable reliable management of the security without Using additional mechanical guide elements.
  • the rear one in the conveying direction Module can be slightly set back compared to the front (e.g. by 1 mm).
  • the front one Edge of the banknotes in one after leaving the front panel of the rear module encountered the front panels of the second module at a certain angle.
  • the inclination of the second front plate forces a small change of direction. As a result, it will leaf-like object curved. Because of a certain inherent stability, the bend leads to that the bank note in the area of the scanning axis of the second module is in contact with the Front panel stands.
  • the relocation of the second module compared to the first can be in addition to Determine the place where the banknote hits the front plate.
  • the integrated optical modules - viewed in cross section to the longitudinal axis - are included Advantage asymmetrical.
  • the optical scanning axes of the neighboring modules can be be brought closer to each other in this way.
  • the modules are basically identical (albeit working with different wavelengths) and almost reversed laid alongside each other.
  • the wavelength range of one module can be in the visible and that of the other are outside the visible spectrum.
  • a module with a green Light and the other work with infrared or UV light. But it can do more be provided as two wavelength ranges and a corresponding number of modules. Basically each module works monochromatic. But it is also conceivable that e.g. one of the modules processed several wavelengths.
  • An optical module suitable for detection extends over the entire width the transport path of the securities.
  • Securities are e.g. several light sources arranged at regular intervals (e.g. LEDs) integrated. Instead of individual point light sources, too a fluorescent tube or the like may be provided.
  • the optical scan axis is represented by a larger number of imaging elements (e.g. rod lenses) on optical detector points pictured. The number of detector points usually corresponds to a multiple (e.g. 10 times) the mapping elements.
  • the whole arrangement is in one tightly sealed, prismatic (e.g. square in cross section) housing with a transparent cover.
  • a transport roller is advantageously provided opposite the optical modules. This pushes the banknote onto the transparent front of the modules.
  • the mentioned role can be found approximately in the middle between the modules (i.e. at the transition of the adjoining fronts). For example, she makes contact in the area of the rear edge of the front front panel in the transport direction. the goal is ensure with a single roller that the security (especially in the Area of the scanning axes) is in contact with the modules, so that a constant optical Imaging quality is given.
  • the entire device (feed, transport track, storage, etc.) is preferably designed such that the banknotes (or securities) are transported and processed in the transverse direction can be. With a given transport speed, more can be done Banknotes are processed per unit of time. There is also a deviation from the correct one Location less critical.
  • Fig. 1 shows schematically a section of an arrangement for checking and storing or sorting banknotes 2. These are of a more or less complex System of rollers, baffles etc. from an input slot to a note storage transported (not shown). Located in a suitable location on the transport system the reading station 1.
  • the reading station 1 is of interest to you scans the banknotes 2 conveyed by the feed, not shown, identifies them and checks their authenticity.
  • FIG. 1 two roles 4.1, 4.2 are shown as an example, which then capture the banknote 2 at the reading station 1 and on a predetermined one Transport path 9 away in the desired direction.
  • the banknote 2 is fed to the reading station 1 in a comparable manner.
  • the upstream and downstream pairs of rollers ensure reliable transport brought as close as possible to the reading station 1.
  • a role 3 over the Reading station 1 is provided, which the banknote 2 to the transparent front plates 10, 11th presses. It can be seen that the roll 3 is mounted and arranged so that the banknote 2 is pressed in the area of the rear edge 10.1 of the front panel 10.
  • the reading station 1 comprises two optical modules 5, 6. These are through a holder 7 hold parallel but slightly tilted to each other. As can be seen from Fig. 1, the Tilt angle on the order of e.g. 5 °. The two front panels 10, 11 are thus not parallel to each other. It should also be noted that at the transition between the two Modules 5, 6 the front plate 11 with respect to the front plate 10 in one direction perpendicular is slightly set back to the transport path 9 (e.g. 1 - 3 mm).
  • the bracket 7 carries e.g. also a connector 8. This is basically the hardware interface between the modules 5, 6 and the electronics (not shown) for evaluation of the signals.
  • the electronics are on one or more Boards 18 housed, which are also inserted into the housing of the reading station 1 are.
  • the boards 18 extend e.g. perpendicular to the transport path (in Fig. 1 after Left).
  • the two optical modules are constructed essentially identically. The following will therefore only module 5 described in more detail.
  • the longitudinal axis of the module 5 is perpendicular to the plane of the drawing in the illustration in FIG. 1 (i.e. parallel to the axis of rotation of roller 3).
  • the housing of the module 5 is in cross section e.g. square.
  • On the front is the transparent front plate already mentioned 10 arranged.
  • Module 5 contains both the light source and the photodetectors integrated.
  • With a module length in the range of 15 to 25 cm 30 to 60 light-emitting diodes 12 are, for example, at regular intervals via the Distributed length.
  • the radiation cones of the light emitting diodes 12 can overlap, so that a illumination that is as uniform as possible is achieved.
  • the scanning axis 17 is provided with a series of rod lenses 13 (or other suitable optical ones Imaging elements) on CCD detectors 14 on the rear wall 15 of the module 5 pictured.
  • the number of rod lenses 13 is greater than that of the light emitting diodes 12. At 20 to 40 light-emitting diodes 12, for example, 100 rod lenses are provided (that is, about 4 to 8 times more).
  • the individual pixels of the CCD detectors 14 are very small in relation to the aperture of the Rod lenses 13. Typically there are several along the length of the scan axis shown distributed a thousand pixels.
  • the structure of the module 5 is asymmetrical in cross section.
  • the scanning axis is therefore not in the middle of the front plate 10, but closer at the edge 10.1.
  • the second module 6 is constructed or arranged as a mirror image of the module 5. Its scanning axis is offset from the center towards the edge 11.1. To this It is achieved that the distance of the scanning axis is smaller than the width of an individual Module (e.g. 2/3 of the width).
  • the front plates 10 and 11 meet preferably offset to each other.
  • the banknote 2 is therefore at an angle of e.g. a few degrees the front panel 11 and is deflected accordingly.
  • FIG. 2 schematically shows the arrangement according to FIG. 1 in a top view.
  • the banknote 2 is guided past the modules 5, 6 in the transport direction 16.
  • the longitudinal edge 2.1 the bank note 2 is transverse to the transport direction 16.
  • the scanning axes 17, 18 of the modules 5, 6 also run transversely to the transport direction 16 and have a minimal mutual Distance.
  • the side edge of the banknote 2 is not predetermined by appropriate guide means of the transport system, but determined when processing the data. So it doesn't matter which one Position takes the banknote 2 in the direction perpendicular to the transport direction 16. Of the The edge and thus the position of the feature to be checked is calculated from the image data. This has the advantage that notes are completely without special hardware precautions different sizes can be processed.
  • the reading station carries out a test on the basis of optically detectable Characteristics of the banknote. For example, predetermined areas of the banknote be tested with the help of pattern recognition methods.
  • the basis of the analysis form the image signals that are used with the modules in different spectral ranges (e.g. green, red, infrared) were scanned.
  • a monochromatic detection can be done using a monochromatic Light source or a monochromatic photodetector and / or by use appropriate filter can be reached.
  • the device according to the invention is simple Means a quick and reliable examination of securities with the help of optical Pattern recognition allowed.
  • the invention is particularly suitable for applications in Banking sector (semi or fully automatic bank safes, automatic switches for the Depositing and withdrawing cash). Another possible area of application could be automatic verification of identity cards or other personal documents be.
