Definitions

  • the invention relates to a device for checking the authenticity of banknotes with a guide slot for the banknotes having housing having on one side of the guide slot a lighting device with light emitting diodes for infrared radiation and on the opposite side a sensor for the transmitted light and an evaluation circuit a display device receives.
  • housings are used with a guide slot, which is pulled through along the banknote to be checked. Since an illumination device with light-emitting diodes for infrared radiation is provided on one side of the guide slot and a transmitted-light sensor is provided on the opposite side of the guide slot, a scanning line of the banknote is detected in transmitted light when the banknote moves past between the illumination device and the sensor, so that the detected Scanning line can be checked in an evaluation circuit.
  • a disadvantage of these known devices is that due to the necessary relative movement between banknote and housing these devices are used only as a standalone units in which hardly any space problems in terms of accommodating the lighting device, the sensor, the evaluation circuit and the power supply occur in contrast to handsets.
  • the invention is therefore based on the object, a device of the type described for verifying the authenticity of banknotes so that an easy-to-use handset can be obtained with relatively small housing dimensions.
  • the guide slot is designed as a plug-in receptacle for the bank notes
  • the sensor has a line-shaped detection area extending essentially over the length of the plug-in receptacle and that the illumination device has a light-emitting diode distributed over the detection area of the sensor a Lichtleitplatte parallel to the plug-in receptacle
  • the insertion of the socket opposite end face of the row of light emitting diodes opposite and the insertion of the plug receptacle facing end face forms a reflective deflection for the radiated from the light emitting diodes in the light guide plate infrared radiation.
  • the requirement for easy handling is created because no relative movement between the sensor and the banknote is required for checking a banknote.
  • the receptacle forming a receiving slot for the banknote holds the banknote in a position predetermined relative to the sensor, which has to have a line-shaped detection area extending substantially over the respective length of the banknote to be checked in order to detect a scanning line.
  • This means that the lighting device must ensure a uniform over the line detection area irradiation of the sensor with infrared light, in a manner that allows small housing dimensions across the socket, because just these housing dimensions are crucial for easy handling of the device.
  • the illumination device comprises a series of light-emitting diodes which are distributed over the detection range of the sensor and radiate the infrared radiation essentially parallel to the plug-in receptacle in the end face of a light guide plate, with the help of which the infrared radiation not only evenly distributed over the length of the detection range of the sensor, but also on the front side opposite the Einstrahlseite over an inclined, reflective surface deflects against the detection range of the sensor, so that an inserted into the socket bill can be detected by means of the sensor in transmitted light.
  • the sensor for detecting an infrared radiation reflected by the banknote be assigned a light guide strip laid along the line-shaped detection area with at least one light emitting diode for emitting infrared radiation into the light guide strip, along the invisible reflection features attached to the front side of the note the entry line.
  • the predetermined for the banknote verification position of the banknote in the plug-in receptacle can be ensured in the banknote verification, may be provided within the plug-in receptacle in the area of the reason of the plug-in receptacle, a non-contact sensor for the proper location of the bill.
  • a substantially rectangular housing 1 which forms a guide slot for the banknotes in the form of a plug-in receptacle 3 in the end wall 2 a longitudinal side.
  • a sensor 4 and on the opposite side of a lighting device 5 is provided on the one side of this shaft-shaped plug-in receptacle 3.
  • Fig. 2 provided with a line-shaped, substantially over the length of the plug-in receptacle 3 extending detection area 6, which is acted upon by the infrared radiation of the illumination device 5 in the transmitted light of the bill to detect the determined by the line-shaped detection area 6 scanning line of the bill.
  • the infrared radiation is indeed absorbed differently by the banknote along this scanning line, so that the patterns of infrared radiation detected along the scanning line can be compared with the stored banknotes to identify the authenticity of the checked banknotes with stored stored comparison patterns, according to a conventional evaluation in a corresponding Evaluation circuit to show the authenticity of the bill.
  • the display device 7 can be advantageously formed by light emitting diodes.
  • the illumination device 5 has a number of distributed over the length of the detection range 6 of the sensor 4 LEDs 8, which are arranged outside the plug receptacle 3 and radiate the infrared radiation in a light guide plate 9, in the region of the insertion opening 10 of the socket 3 opposite end face like this one Fig. 1 can be removed.
  • the light guide plate 9 forms an inclined deflection surface 11, on which the infrared radiation is reflected against the detection region 6 of the sensor 4, so that a banknote inserted into the socket 3 is illuminated by the infrared radiation whose course in the Fig. 1 indicated by dash-dotted lines.
  • a contactless sensor 13 can be provided in the region of the base 12 of the plug-in receptacle 3, which sensor is formed, for example, by an infrared light barrier.
  • the housing can be made with a comparatively small thickness be formed transversely to the receptacle 3, because in particular the light emitting diodes 8 of the illumination device 5 according to the plug-in receptacle 3 parallel Lichtleitplatte 9 between the slot of the receptacle 3 and the housing wall can be arranged parallel to the receptacle 3 and therefore emit the infrared radiation substantially parallel to the receptacle 3 , Due to the slightly larger space requirement for the sensor 4 and the evaluation circuit in the direction of the housing thickness is sufficient space on the side of the sensor 4 for a rechargeable battery 14 for power supply.
  • a piezoelectric warning buzzer 15 can be provided, which displays a banknote whose scanning resulted in a pattern of the infrared radiation recorded which does not match the stored comparison data.
  • the sensor 4 can also detect an infrared radiation reflected at the banknote.
  • a light guide strip 16 can be provided along the line-shaped detection region 6, which is irradiated from at least one end face by means of a light emitting diode 17 with infrared light which propagates within the light guide strip 16 and radiates from the light guide strip 16 in a line on the inserted banknote, so that the presence of visible in the visible wavelength range not visible reflection features of the bill along the detection line can be monitored via the detection range 6 of the sensor 4 with the aid of reflected infrared radiation.
