(b) Conventional Technology With the recent spread of telephone cards, there is a demand for the sale of telephone cards through vending machines. When selling this telephone card in a vending machine, it is conceivable to use a machine exclusively for telephone cards, or a machine that sells the machines together with other different types of products. For example, as shown in Japanese Utility Model Application Publication No. 01-74179, there is a product delivery device for cigarettes that stacks and stores box-shaped products and pushes out the lowest product by a delivery member, and in Japanese Utility Model Application Publication No. 60-9843. It is conceivable to install a telephone card delivery device, as shown in the figure, in the vending machine body, which sends out the lowest stacked paper sheets using a delivery roller.

(c) Problems to be solved by the invention However, if such a combined selling machine is installed, the number of cigarette delivery devices installed will be reduced and a telephone card delivery device will be installed, resulting in a decrease in the number of cigarettes sold. This is problematic, and managers of cigarette vending machines do not necessarily want telephone cards to be sold at the same time, and it also varies greatly depending on the location of the vending machine. There was a problem that needed to be prepared.
