Description

Electronic coin validator.

The invention relates to an electronic coin validator.

Coin validators of this type usually only require a low no-load current. Some particularly advantageous electronic circuits, however, require a relative large no-load current, so that in certain cases this increased power consumption interferes works.

But also the common designs need in special cases still too much electricity, e.g. when operated from a battery # for a long period of time Need to become.

In such cases it may be desirable to use the electricity only for the to switch on the actual coin checking time.

This is not the case with all electronic coin validators - e.g.

because of long settling times - possible, so suitable suggestions for the implementation of an electronic coin validator are missing the requirements and Bringing possibilities to a common denominator.

The object of the invention is therefore to provide an electronic coin validator or to propose possible solutions which are economically cheap and reliable / characterized by the lowest possible @ permissible no-load current consumption are.

In all cases, according to a proposal of the invention, the coin slot is used (one slot or several slots) by one or more monitoring switches supervised.

Xan can have its own switch for each slot and channel assign, but you can also assign all channels or slots with just one switch monitor.

In all cases where several different types of coins are used by one common throw-in channel are accepted, you have to use the reporting function be satisfied with the one switch.

According to one idea of the invention, however, one can apply to all others Cases by means of the switch (s) not only report the coins, but also make them available monitor an important coin parameter - namely the diameter.

In cases where each coin location has its own slot assigned to it is, this will always be calibrated to the dimensions of a certain coin location, i.e., he will not allow the insertion of coins that are too large or too thick.

The monitoring switch on the track of a certain type of coin can therefore monitor very precisely according to the invention whether the inserted coin is about does not have the required diameter. The following examples explain this in the Individual.

But also when every coin has its own career and these together can be monitored by just a single switch, according to another proposal this single switch monitors the diameter of the different types of coins Take over the diameter if you use the individual Münzlahfbahnen according to the invention one will then arrange the running tracks so differently in height, that the vertices of all types of coins lie on one line (height) and then a single beam of light or a mechanical feeler lever means that the value falls below one can determine certain durhhmesuers.

Examples of this are also shown below.

According to a further idea of the invention, one can now not only the entire supply current for a coin measuring circuit - either for a means Timer specific or for a controlled time - on and off, rather you can also permanently tile a reduced quiescent current for critical components leave and then switch on the actual measuring circuit in whole or in part.

The illustrations center some arrangements according to the invention: Fig. 1 shows an apparatus wall 1, an insertion slot 2 made therein and an adjoining Münzlaufkanal 4 and one shielded to the maximum dimensions of the coin type in question Limitation 3. The coin is denoted by 5, which is only the measuring sony for the nominal size 6 can excite, and not if it is undersized.

Fig. 2 shows a light barrier that monitors several running channels. The running floors of the three coin running tracks are shown stylized with 1, 2 and 3. 10, 20, 30 are the different sized coins. The one between transmitter 4 and receiver 5 beam formed by a light barrier is interrupted in the presence of a coin.

Fig. 3 shows a similar arrangement with the same designations. The light beam is bundled by means of perforated diaphragms 40 and 50 and is therefore very recognizable.

The floors of the runner channels are supported in terms of height so that all vertices of the different sized coins are aligned and that each type of coin is only reported can be, if it shows no undersize.

Claims (6)

P a t e n t a n s p r ü c h e. 1. Electronic coin validator, characterized by an between Coin slot and measuring arrangement arranged monitoring switch, which the Reports the insertion of a coin and switches on a measuring circuit in whole or in part. 2. Coin validator according to claim 1 in the presence of several insertion slots and runner channels for coins, d u r c h e k e n n n e i c h n e t that the Monitoring switch monitors several running channels. 3. Coin validator according to claim 1 and 2, d a d u r c h g e -k e n n z e i c h n e t that the monitoring switch (s) are designed in such a way that they monitor the diameter of a certain type of coin. 4. coin validator according to one or more of claims 1 - ^ 3, d a d It is noted that a monitoring switch controls the diameter several coins of different sizes monitored and that this is monitored by a different high order of the bottoms of various channels for the individual coin locations achieved so that the vertices of the different sized coins are all on one Line lie. 5. coin validator according to one or more of claims 1-4, d a d u r c h g e k c n n z e i c h n e t that the monitoring switch (s) the intervention to be carried out by them. Timing element for each one specific Take over time. 6. coin validator according to one or more of claims 1-4, d a d Acknowledgments that the monitoring switch (s) operate the take over the engagement to be made by you for a controlled time, the ton a coin running through the coin validator is ended.
