Coin checking device for self-sellers, in particular coin-operated telephones

Mechanical coin testing devices for self-sellers and coin-operated telephones are known. The key point of these coin testing devices is usually referred to as the coin channel with regard to the passage of coins. It is completely independent here how much and which test equipment a test device contains. These conventional coin checking devices are adjusted in a Vorri ^ device and then fastened ax .Screws in the devices for which they are intended. Since actuators inevitably intervene to or from the outside in the case of mechanical coin checking devices, interlocking conditions are always observed which may require readjustment.

As is well known, the electronic coin checker wins more areas of application, as this test method differentiates coins more precisely, especially with regard to their material can, so that the high demands placed on the coin check in terms of security and economy can also be better fulfilled. For this purpose, those in a coin are preferably used by a Eagnetic test point alternating field used eddy currents generated and the reaction of the magnetic Field of these eddy currents on the test point or · on evaluated a secondary coil.

In the case of mechanical coin testing devices, the testing centers can monitored, checked and serviced in the device will. This means that the maintenance service at a

If the fault has occurred, it can recognize the fault on the spot and also correct it electronic coin checking devices without very extensive Test equipment, such as oscilloscopes, is not possible, so that a fault can be rectified by Repair of the coin checking device in the one used € re ~ ä "v is not easily feasible? electronic switching devices that make up a coin validator is composed, namely require a laboratory maintenance service that is economical can only be carried out at a central point.

The hiring is based on the task of the coin checking devices so that the maintenance service can be carried out as simply as possible. This object is achieved in that the coin checking device as a plug-in Unit is formed. In this way, easy interchangeability is given. With the solution After the hiring it is possible to check the puncture capability of a coin checking device on the spot to control by means of an adapter and faulty devices quickly against operational coin checking devices to exchange. This ensures that the maintenance service is also carried out by auxiliary staff that only have to be able to prevent the failure of a coin checking device in a device used determine and be able to replace them with a new unit. This becomes the direct maintenance service at the established self-sellers in terms of expenditure on skilled workers and material significantly reduced. The defective test facilities that have been removed can then be returned to a central location using laboratory means be repaired again.

Hacii of a further training of the hiring is always one electronic test center with the corresponding ejector

Einrientring arranged on a plate-shaped structural unit. This ensures that the electronic test station and the associated evaluation circuit for each coin value are to be united on one plate. This solution significantly simplifies the entire arrangement in the Device and thus also maintenance, since only the faulty & anai replaced serdea S

The building units after the hiring are expediently designed in such a way that that they only have one coin entry and two coin exits for the coins to be accepted and rejected exhibit.

Further details of the furnace emerge from the exemplary embodiment described and illustrated below.

In the figure, the coin feed 1 can be seen at the top left, while the coin discharge can be seen in the lower part for rejected coins and coin derivation 3 for accepted coins. The inserted coins run along a coin path 4 (channel) to an electronic test station 5, for example from a Probe coil consists. In the field labeled 6, an electronic evaluation circuit is housed, which for example evaluates the impedance changes and passes them on to a non-illustrated executive organ. Before the Test point 5, a terminal point 7 is indicated by dashed lines. Hit 8 is one from the executive organ, preferably one Magnet, controlled lever, which, depending on the test result, guides the coin into the Coin derivatives 2 or 3 determined. In the coin derivation there is a reporting point 9 for the accepted coins, through which the accepted coins are registered. Crooked and bent coins are already sliding

20 Before the coins get into the coin feeder, they first have to be pushed through a coin slot attached to the housing of the self-seller, as a result of Leu, coins that are too large in terms of their diameter or thickness are already being rejected.

25 This slot is expediently designed in such a way that that aas insertion of bent or deformed coins is prevented. This can expediently done in that the side surfaces of the Sinwurfschlitzes are provided with a profile that is transverse to
