Abstract

A vending machine which measures the weights of a retaining vessel, having commodities, so as to determine the difference in weight before and after the removal of commodities as an electrical signal. An in-line system includes a locking access door for taking out commodities from the machine by inserting a lock-releasing medium into the automatic vending machine. An off-line system includes a system for storing nomenclature, quantity, price and the like of commodities to be purchased by inserting a storing medium into the automatic vending machine. For insuring an accurate quantity of commodities to be purchased, and prevention of an unlawful act or purchase, there is provided a system for indicating a quantity and weight of commodities, prior to purchase, a radiant energy source for forming a beam curtain covering the front of a body proper of an automatic vending machine, a heater exchange maintaining a door and a weighing scale in a certain temperature range, and a warning system for issuing an alarm signal and a communicating signal, when commodities are purchased unlawfully. An off-line system permits automated accounting, so that man power of employees may be saved to a large extent, with accompanying improvements in control of commodities. A purchaser may check and select commodities in one'"'"'s hands before purchasing.
