Definitions

  • the invention relates to a device for detecting the value of coins with a cover body which can be attached to a container for collecting coins and has a slot through which coins to be registered of different sizes, each characterizing a coin value, can be introduced into the container , a measuring device for measuring the size of each individual coin and a registration device for registering the value of the coins moved through the slot.
  • Such a device is known from GB-A-2 198 118.
  • an attachment with several slots of different sizes is arranged on a container for collecting coins, which are matched to the coins to be registered.
  • a sensor is assigned to each slot, which detects coins inserted through them.
  • This essay takes up a lot of space, especially when many different coins are to be registered.
  • GB-A 2 198 118 also indicates the possibility that only one slot could be provided which is equipped with, for example, optical sensors which measure the size of the coins inserted through the slot.
  • the object is achieved in a device of the type described above in that the slot is delimited at least at one point by a slide, the slide is normally held in a rest position by a constantly acting load, in which the slot for introducing the smallest registering coin is too small, the slide can be deflected into a measuring position dependent on its size by a coin pressed into the slot and the measuring device is designed to measure the deflection of the slide.
  • Such a device has the advantage that the coin does not have to be measured directly, for example by scanning it with optical sensors, but the sensor system can be attached at a different location than directly at the area through which the coin is guided.
  • the measuring device is particularly reliable. Since such a deflection can be measured at very small intervals, it can be adapted to a large number of coin sizes, even in different currencies.
  • the fact that the slot is closed very far in the rest position prevents coins which are to be registered from being inadvertently guided past the measuring device. The slot can even be closed completely, which prevents dirt from entering.
  • the slide can be pivoted. However, the slide is preferably guided in a straight line. Such a slide can be accommodated in the slot in a particularly space-saving manner and enables linear measurement of the displacement of the slide in a simple manner. In general, it is sufficient if the slot is limited on only one side by a slide. However, several slides can also be provided, for example one for measuring the diameter and a second for measuring the thickness of the coins pushed through the slot.
  • the constantly acting load is preferably the bias of a return spring which is arranged between the slide and an abutment. Gravity can also be used as a constantly acting load. For this, however, the device must always be oriented in a certain way. The use of electromagnetic fields or the like would also be possible. However, the use of a spring is particularly inexpensive and effective.
  • At least one electrical contact for measuring the deflection of the slide is preferably closed in each measuring position of the slide. Measuring the displacement of the slide by electrical means is particularly advantageous if an electronic registration device is used; the measurement signals can then be fed directly to the registration device.
  • each coin to be registered is assigned a different electrical contact, which is closed by the slot when the coin is pressed in.
  • Such an embodiment can be implemented, for example, by means of electrical conductor tracks on a printed circuit board which are guided to different deflection positions of the slide. The slide then moves a bridging element which closes a circuit via the contacts when the slide is deflected accordingly.
  • An electrical signal can be obtained from a closed contact, for example by voltage measurement. With this signal at exactly this contact, the respective coin can be uniquely identified in a simple manner.
  • Contact points are advantageously arranged in such a way that a different electrical contact is assigned to each coin even when changing to certain other currencies.
  • the electrical contact is advantageously formed by a contact body mounted on the slide.
  • a metallic contact body can bridge the contact points, for example.
  • the slide is connected to the actuator of a potentiometer so that the actuator is actuated when the slide is deflected, and a different electrical potential is associated with each coin to be registered.
  • the embodiment with a potentiometer is advantageous because an electrical potential is directly associated with the deflection of the slide. If a corresponding voltage is measured precisely, the deflection can also be determined precisely.
  • Such an embodiment can be converted particularly easily to other and additional coin types, the size of which differs from that of the previous coin types.
  • the registration device is advantageously also designed as a processing direction, which processes the registered values of the coins and outputs a signal to a display device to display the values of the last registered coin and / or the sum of the values of a large number of coins registered in succession.
  • the user By equipping the device with a display device (e.g. an LCD display or a light-emitting diode display), the user receives the desired information as soon as the coin is inserted. By displaying the coin value, he can check whether the device has registered the coin correctly. By displaying the sum of the values of several coins registered in succession, the user can obtain information about his saving behavior. The total sum of the value of the coins collected in the container or how much money the user has saved in a certain period of time can be displayed (when the processing device is connected to a clock).
  • a display device e.g. an LCD display or a light-emitting diode display
  • the amount can also be displayed in different national currencies, and especially before the introduction of the European currency in the unit "EURO", so that the user is prepared for the introduction of this currency.
  • an acoustic display can be provided. For example, a beep may sound when a coin is inserted or when it is successfully detected. Several beeps of different heights can represent the respective coins. Electronic voice output is also possible, through which the user receives information of the type described above.
  • Programming of the processing unit via at least one electrical contact is also possible, advantageously e.g. to convert the system by the user to coins or currency systems to which the device is not adapted from the outset.
  • This electrical contact is preferably closed when the slide is deflected from the rest position, i.e. is programmed via the slider. This has the advantage that no separate controls have to be attached to the device. The slide can be easily deflected using a coin.
  • the registration device can also be designed to record the time course of the deflection of the slide from the rest position over at least a certain period of time. This provides the possibility of additionally detecting whether a coin has actually been pushed through the slot (into a container), because when the coin is pushed in and pulled out again, the slide remains deflected longer than when the coin is pushed through.

  • the embodiment of FIG. 4 offers a certain advantage in this point because the contact surfaces 40 are applied to the base plate 15 and thus protrude somewhat (approx. 40 ⁇ m).

  • the arm 72 of the actuator 73 rotates by a more or less large angle depending on its position when the slide 4 is displaced by a certain fixed distance.

  • the microprocessor can be programmed by deflecting the slide 4 as far as it will go.

When the desired selection is reached, the slide 4 is released and the programming is done. For example, the currency can be changed by assigning different numbers to the different currencies, which are successively run through on the display 6.
