Beverage vending machines are known that are configured to take out a predetermined amount of raw materials when opened, mix the raw materials with a predetermined amount of diluent to make a beverage, and vend the beverage automatically.

In this way, the beverage vending machines that are currently in practical use have a single-layer material stocker, which means that the number of material stockers is small and it is not possible to respond to the diversification of user tastes. Beverage vending machines had to be placed side by side in one place, or larger vending machines with larger widths and depths that could sell a variety of beverages had to be prepared.

[Problems to be Solved by the Invention] However, with this approach, there are problems in that the installation cost increases and a large space for installation and a power supply corresponding to the number of vending machines are required.

Therefore, in order to store many raw materials in one beverage vending machine, for example,
As shown in the publication, the problem can be solved by stacking the raw material stocker in two layers instead of one layer.
Even with a simple two-layer stacked structure, when considering the replenishment of raw materials, a stepladder must be used to raise and lower the upper material stocker, and especially when replenishing the lower material stocker, the upper material stocker must also be raised and lowered. There is a problem.
