PROBLEM TO BE SOLVED: To reduce the operation of a controller by the manager of an automatic vending machine. SOLUTION: The automatic vending machine is constituted of a switch 12 for outputting a signal when a lock member 10 comes to a prescribed rotation position by an opening/closing key and of the controller for receiving the signal from the switch 12 (when the switch 12 becomes an ON state) and changing-over a control state from a charged sale into a free sale. Then the changed sale and the free sale are easily changed-over by the operation of the opening/closing key without performing a changeover operation in the controller by opening a main door so that the operation of the manager of the automatic vending machine is reduced.
