ABSTRACT:
Procedure for detecting the operation of the coin return mechanism in coin selectors, especially in selectors having a passage through which the coins pass, which can be opened for the recovery thereof, and having at least one coin passage detector, the operating conditions of which are sensitive to the passage of the coins and to the opening of the passage. The procedure consists of detecting the alterations in the operating conditions of the said detector caused by the opening of the channel. These alterations result in changes of amplitude and frequency which are measured, for example, by the microprocessor of the selector, and differentiated from the alterations due to the passage of a coin.
