On the other hand, a vending machine that dispenses the final sale product by combining each component requirement such as water, coffee, sugar, and paper cups, such as a coffee vending machine, will stop selling the product if any one of the configuration requirements is exhausted. In this state, the system is equipped with a currency return system in which the entered money is automatically returned. According to the money return system, even if the product is stopped and the money is returned to the vending machine due to the buyer's carelessness, the money is returned immediately. The buyer's dissatisfaction due to the suspension situation is not greatly caused.

On the other hand, in the case of small vending machines that do not have a currency return system, when the sale of a product is stopped, a simple warning that the buyer does not use the vending machine by emitting a warning lamp with the words “Sold out” or “Suspended”. We adopt system.

However, according to the automatic vending machine adopting such a simple warning system, when a product is stopped, the buyer cannot not return the input money and actively prevents the input of the money. It often happens that the vending machine manager has to take action to return the entered money to the buyer.

The present invention was devised to solve the above-mentioned problems, and when the sale of goods is stopped, a coin is not introduced into the coin guide so that the vending machine can prevent the problems caused by the wrong coin input, and can be operated efficiently. It is for the purpose of providing.
