Abstract
A special door is added to the coin receiving mechanism of a pay telephone or other vending machine to discourage the practice of stuffing the mechanism with paper or other foreign matter to trap deposited coins. A slot in the door is normally aligned with the regular slot for coin deposit. If stuffing occurs, the door slides over, misaligning the two slots and preventing deposit of any further coins.
