Abstract: An automatic vending machine includes: product storage shelves provided along an up-down direction in a product storage region inside a product storage; a back face duct configured to extend along the up-down direction behind the product storage region; a circulating unit configured to flow air inside the product storage into the back face duct from an air inlet of the back face duct to circulate the inside air between an inside of the product storage region and an outside of the product storage region; a temperature adjusting unit configured to adjust the inside air circulated by the circulating unit to a desired temperature; and a side face duct configured to extend along the up-down direction at a place corresponding to front end portions of the product storage shelves in at least one of both side regions of the product storage region, and communicate with the back face duct.

Abstract: A vending machine includes: an in-storage heat exchanger installed in an airtight heat-insulated commodity storage inside a vending machine body and configured to exchange heat between a refrigerant passing through a refrigerant flow path of the in-storage heat exchanger and inside air that is air inside the commodity storage, through a fin member; and an out-storage heat exchanger installed outside the commodity storage inside the vending machine body and configured to exchange heat between a refrigerant passing through a refrigerant flow path of the out-storage heat exchanger and outside air that is air surrounding and outside the commodity storage, through a fin member. The fin member of the in-storage heat exchanger includes louvers configured to cause the inside air passing through the airflow path to generate a meandering flow. The fin member of the out-storage heat exchanger has no louvers.

Abstract: A stopper which projects into the product passage to support the product to be sold, an ejector which projects into the product passage to support the product to be sold next immediately after the product to be sold, and control means for controlling the projection quantity into the product passage of the stopper and the ejector, wherein the control means, upon receipt of a sales instruction, allows the ejector to project into the product passage to support the product to be sold next, opens the stopper to deliver the product to be sold from the product passage to a sales port and closes the product passage with the stopper after the delivery of the sales product while supplying the product to be sold next by recessing the ejector. As a consequence, irrespective of the size and the configuration of the product to be sold, only the product to be sold can be delivered with certitude at the time of selling the product.
