Definitions

  • European Patent Application 164 110 discloses a coin discrimination apparatus comprising electro-magnetic detecting means for detecting as an electrical signal a physical characteristic of a coin, an analog-to-digital converter for converting an output of the detecting means to a digital signal and furthermore comprising a memory device for receiving as an address signal the digital signal generated from said converter and for storing a finally signal.
  • electro-magnetic detecting means for detecting as an electrical signal a physical characteristic of a coin
  • an analog-to-digital converter for converting an output of the detecting means to a digital signal
  • a memory device for receiving as an address signal the digital signal generated from said converter and for storing a finally signal.
  • the invention has the object to improve the coin handling mechanism of the kind mentioned above such that the mechanism is easy to manufacture and that the mechanism can detect coins made from known magnetic materials.
  • the electro magnetic sensor comprises at least one pair of coils disposed on, opposite sides of the coin path, each coil having an electro-magnetic field which intercepts the coin path, there being an oscillator to excite the arrangement and means to determine the electro-magnetic properties of a coin passing through the electro-magnetic fields of the coils.
  • each coil is directly connected to one output of an oscillator the oscillator having a further output which is connected to a microprocessor.
  • the microprocessor being adapted to process the signals supplied to it to determine the characteristics of the variations experienced by the oscillator during the passage of a coin through the said electro-magnetic sensor.
  • the output of the oscillator that is connected to the micro processor is connected to the micro processor through a rectifier and an analogue-to-digital convertor
  • a further output of the oscillator is fed to the microprocessor as a clock input.
  • the microprocessor comprises the means to determine the acceleration and preferably additionally the speed of the coin between the photo-electric sensors.
  • a coin handling mechanism in accordance with the invention is adapted to receive a coin 1 and to direct the coin along a predetermined path 2.
  • the predetermined path is not horizontal and is thus inclined downwardly or is vertical, so that the coin passes along the path under the influence of gravity.
  • the coin will, of course, move along the path with a velocity and an acceleration determined by the mass of the coin.
  • the coils 6 are directly energised by an oscillator 7.
  • An output of the oscillator 7 is connected to a microprocessor 8 to provide a clock input signal for the microprocessor and a further output of the oscillator 7 is passed through a rectifier 9 and an analogue-to-digital convertor 10 to the micro processor 8.
  • an automatic compensator 11 is provided connected between the rectifier 9 and a control terminal of the oscillator 7 to minimise a risk of any long term variation of the amplitude or frequency of the oscillator.
  • the optical checking zones 3 and 4 are also connected to the microprocessor 8.
  • the micro processor 8 is associated with a memory 12 and is provided with output terminals 13 and control input terminals 14.
  • a coin 1 is inserted into the coin handling device and falls, under the influence of gravity, following the path 2.
  • the coin enters and leaves the sensor 3.
  • the moment that the leading edge of the coin intercepts the beam of light between the photo-diode and the photo-transistor is effectively recorded in the micro processor 8, as is the instant that the light beam is re-established as the trailing edge of the coin leaves the sensor 3.
