<p>Coin sensor system for automatic vending machines, used preferably in all automatic machines and apparatus which are operated by inserting coins and which are power supplied by batteries. The sensor system comprises a metal body (3) integral with the structure of the selector (1) arranged in relation to the introductory slot of coins into the selector wherein the coins bump into each other. Sensor means are provided to detect the mechanical vibrations of the collisions or impacts of coins with the metal part in order to transform such mechanical vibration into an electric vibration, means for cleaning the square wave provided by the comparator, means for activating the switch for supplying power to the electronic coin control and measuring system, and means for desactivating the power supply switch to the electronic control and measuring system. <IMAGE></p> |
