ABSTRACT:
A vending machine having an anti-pilferage door mechanism with a delivery door interconnected through linkage to an anti-pilferage door and a rear door which come together to close off the opening for the product storage area to the product dispensing chamber when the delivery door is opened by a customer thus preventing any opening which would allow a pilferage device such as a wire to be inserted through the delivery door opening up into the product storage area. The linkage which connects the delivery door to the anti-pilferage door and rear door is on one side of the dispensing chamber and a spring biasing mechanism is mounted on an opposite side of the chamber and assists in biasing the delivery door closed while providing a force reduction exerted by the spring as the door is opened.
