TLDR
In this paper, a device for receiving or rejecting coins or circular tokens, for example for coin- or token-operated telephone apparatus, is described, which comprises, for the chute down which the coins drop, a pivoting flap of which the state, retracted or not due to the weight of an incidental coin, is determined by a piezoelectric element.Abstract:
This invention relates to a device for receiving or rejecting coins or circular tokens, for example for coin- or token-operated telephone apparatus. It comprises, for the chute down which the coins drop, a pivoting flap of which the state, retracted or not due to the weight of an incidental coin, is determined by a piezoelectric element, such as a bimorph piezoelectric plate, which serves, or not, as anti-pivot support for this flap.read more
