An actuator that turns ON / OFF the detection switch when pushed, an opening that guides the product dropped from the product tray from the inside of the storage to the outside of the storage, and an inside of the storage provided outside the storage provided at the top of the opening. A shutter opening and closing device that opens and closes the opening by sliding a shutter composed of a heat insulating material that divides the room back and forth, and a cooling device that is installed at the bottom of the vending machine body to cool the storage Since the product transfer device of the vending machine is configured from, the depth dimension of the vending machine body can be configured without depending on the depth dimension of the outlet, and the depth dimension of the vending machine body can be significantly reduced compared to the conventional one. As a result, the work of transportation and installation becomes easy, and the problem of protrusion on the public road at the time of installation and the regulation for installation in a narrow installation place can be greatly reduced. Also, since the shutter that separates the inside and outside of the storage cabinet is made of a heat insulating material, the temperature rise inside the storage cabinet can be suppressed more than before, and the power consumption of the cooling device can be reduced to save energy. Can also fulfill.

Further, a cylindrical hole provided at the free end of the product saucer rotating shaft, a roller C having a columnar rotating shaft and having the rotating shaft pivotally supported by the hole, and a front side inner surface of one side of the storage. A guide rail C that is provided to extend vertically at a position facing the guide rail A and that the roller C follows as the bracket moves up and down.
Even if the product tray is cantilever driven, the roller C rotates and descends while following the guide rail C, so that a large swing of the free end of the product tray when the product tray moves up and down is suppressed. It is possible to prevent the product tray from rising and falling and stabilizing the product conveying posture without the product tray interfering with the product unloading device and the like, thereby preventing the sales stoppage and the product jam due to the inoperability. In addition, even if the dimension between the guide rails A and C varies by Δa due to variations,
Since the rotation axis of the roller C can rotate while moving relative to the hole by Δa in the axial direction, the product saucer rotation axis cannot be sold without being stretched between the guide rails A and C. Stoppage can be prevented.

Also, a transparent plate that occupies most of the front door of the main body and allows the products displayed in the storage container to be seen through, and the cylindrical tube at the top of the front door of the main body immediately behind the transparent plate By providing a fluorescent lamp that is parallel to the front door and in a horizontal state, and using the product tray as a product tray made of a transparent member that is stopped immediately below the fluorescent lamp when waiting for sale, a light source from the outside Also, it is possible to improve the visibility of the displayed products and promote the consumer's willingness to purchase without blocking the light from the fluorescent lamp provided in the main body of the vending machine.

Further, since the product tray is made of a synthetic resin member, the synthetic resin member has a relatively small specific gravity and thus becomes light in weight, so that the product tray can be easily moved up and down even with a driving device having a small output, and power consumption is reduced. Reduction of cost and cost can be achieved. Further, since the synthetic resin member can be easily manufactured into a complicated shape by the manufacturing method, the synthetic resin member has a high added value and can reduce the number of parts of the structure and simplify the structure.

Further, since the product tray is a glass plate, the surface of the product delivered from the product carry-out device is not easily scratched by the impact when the product is dropped on the product tray, so that the appearance is not damaged. .
