Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can vending machine (hereinafter, vending machine), and more particularly, to a method for displaying the can holding amount of a can vending machine which grasps the quantity of cans sold and displays it to the outside.

The can holding quantity display method of the can vending machine of the present invention is a can deck into a can storage deck in a can vending machine including a storage deck for storing cans, a coin mechanism, a display unit, a sales switch, a counter switch, and a microcomputer. A first step of checking and storing the remaining amount of the; A second step of counting the number of cans put into the can storage deck, adding the counted quantity to the remaining amount stored in the first step, and storing the count in the memory; A third step of sensing whether the sale of the can has occurred and if the can has been discharged, subtracting the discharge amount of the can from the last remaining amount stored in the second step; And when the remaining amount of the can reaches zero, the fourth step is to sell out and display it to the outside.
