This invent refers to a new kind of automatic vending machine, conceived and projected to be placed on the wall, having a reduced size to fit in small areas, being very useful for corporate buildings, such as offices, commercial buildings floors, industries, elc. This vending machine is unique in its reduced size, storage capacity, mechanical system, payment and controlling system. The conception of vending machines in general, involves basically three systems: The mechanic, to avail the chosen product; a payment system that executes the purchase and a controlling system that integrates the whole operation. The purchase process in vending machines also follows a certain pattern:

1 - The first condition is to pay for the product by inserting a certain amount of money (notes or coins) inside the machine, or using a credit card or a pre-paid card.

2 - Next step is to indicate the product.

3 - The machine controlling system must approve or validate the operation. 4 - The product is available.

Most of the known vending machines have a large size. They usually occupies around 1 squared meter of floor space and have approximately 2 meters high. Those machines require a large area and cannot be installed in small places. They also require a high selling turnover of products to be commercially viable due to their high costs. That makes those machines unviable for building floors and places with a reduced number of users.

T'he most common mechanical system used in vending machines is made with a spiral rack, with the products placed between its coils. The spiral turns in its own axle moved by a engine placed in one of its ends, moving the products in line to the opposite end, where the first product of the line falls throw a passageway that leads to the exit compartment where the user picks up the product. This mechanical system does not allow the compactness of its components neither of the storage products. It is one of the reasons that contributes for the large size of the machine and its slowness on dispensing the product.

The already known payment systems are those that work by inserting money or inserting a prepaid cards such as magnetic cards, disposable cards or rechargeable cards These systems can be inconvenient and limit the buying. In the money payment system the most common problem is to have change at the time of the purchase and sometimes the machines reject the money. In the case of pre-paid cards, the limitations are availability of pre-paid cards to be bought at the moment, and the inconvenience of buying a card with more credit than needed. This invent has the following innovations.

lvieciiaiiicm a , effective and totally innovator, completely different of all other systems already used in all the existing vending machines . A shown on figure 1, the products are placed in a vertical compartment (1), that has a hole(l.l) in its bottom so that the fist product(Pl), ( the one that is under all the others) can be removed. It is removed out of the base(3), by the action of a battering ram(2) moved by a ingenious handspike(4) attached to a longitudinal movement engine(5), placed under the base(3). Once the product is removed it falls, by the power of gravity to the dispensing pocket(6). Also by the power of gravity the remained products(P2, P3 ...), in the vertical compartment(l) will move down. When the whole sequence of the engine(5) movement is completed the battering ram(2) returns to its initial position, ready to start another sequence, pushing the next product(P2), and so on as shown on figures 2, 3 and 4. A passing sensor(7) detects the passage of the product confirming to the controlling system that the operation was completed successfully. If the chosen product is out of stock, the sensor will not detect the fall and the operation will be automatically cancelled. With such a mechanical system it is possible to optimize the internal space of the machine, so that the components on the system are placed very closed to each other, making a extremely compact set. The storage area is also optimized in the vertical compartment(l), where the products are piled up and there is no free space between them, as well as in the extra storage areas(8) beside the vertical compartment(l) where a extra stock of products(9) can be set and further used to reload the vertical compartment, by the servicing employee, during the refilling time. The result is a vending machine with a reduced size, without compromising its storage capacity. This mechanical system also allows the machine to be very narrow, light and small, easy to be installed on corridors walls, without obstructing the passage. The figures 6(frontal view), 7(side view) and 8(view from the top), indicate one of the possible measures combination for the machine dimensions. Comparing to the conventional vending machines, this invent has more than twice of storage capacity relating to the cubic area, which means that its internal space utilization is highly optimized. This system provides the best utilization of the storage area, since there is no free space in between the products. This whole mechanism works with precision, demands a minimum level of electric energy and is made of long lasting material with low cost and easy maintenance. To fulfill the prerequisites of creating a low cost, easily produced, durable and light vending machine the choice of the materials was decisive. The used engine has a low cost, is produced in wide scale, is dust and liquids resistant, conceived not to need maintenance. Payment System - This invent has a innovative payment system, completely different from all the other systems used on vending machines. It is based on a previous registration of the

users, that can be any kind of corporate employees or any other any other group of people related to a entity, such as students, club members, hotel guests, etc, in another word, the users of the place where the machine is installed. Different from the common system that requires the use of coins, notes or pre-paid cards, in the present system, the users receive a label with a barcode that allows them to consume the products available in the machine. To start the operation the user passes the barcode throw a barcode rcader(8), indicated υn Figure 5.In the case of a invalid barcode, the display(H) will indicate a message of invalid operation. But if the user is regularly registered the machine will recognize the barcode and will start the operation, showing all the steps on the display(14), or giving the explanations by a voice module(9). The user will be asked to chose a product, by pressing a corresponding bottom(13). It is a very intuitive process, once the products are shown on a window(l 1), placed on the machine's frontal area, where it is possible to see the real products and all the information related to each of them(12), such as price, description, nutrition facts etc. Each bottom(13) is placed next to the correspondent product, being very easy to identify. The user does not need to deal with codes or combine numbers to indicate the choice. Once one bottom(13) is pressed the mechanical system starts, dispensing the chosen product in a fraction of a second. All the purchases are saved by the controlling system. The collection is made periodically, through banking transference, deposit, payroll withholding of payment or any another admitted mode of payment, since the universe of users is fully identifiable. The present system, therefore, does not involve money at the moment of the operation, nor prepaid cards. It brings innumerable advantages for the user: the label with the bar code can be stick on any object such as access building card, employee ID card, bank our health plan card, mobile phone device; there is no money change problem; it is not necessary to have the money in the moment of the purchase and there is no need to pay for the product in advance. Concerning the machine operation the servicing employee does not need to carry money.

Besides that, this system allows the users to buy products in other machines at different places even other states or countries, with the same barcode. This system also brings many advantages for the vending machine administration, therefore, it does not involve the money storage inside the machine, preventing the machine to have characteristics of strong box, contributing for the security of its operation and its low cost. This unique payment system for vending machines still can vary on the user recognition device, using biometric readers such as fingerprint, iris, facial recognition, etc. In these cases the user will not need to have a barcode, being registered by the available reader module. Controlling System - as indicated in FIG.9 and 10, the operation is registered in an internal memory that is subsequently transferred to a central office, that will make the storage and

processing of a data base. The transference is made through modem or with data collector. The central office receives the data from the collector or from the modem connection. Through the same connection the central office can modify or up-date the program installed in each machine. This provides extreme agility and interaction with the user, because this connection is regularly made in the moment of refilling the machine. It is also possible to update the cancelled codes as well as sales promotions.

Reloading System - this machine is also innovative in the reloading system. Since there is an extra storage area inside the machine, there are two ways of refilling. In one, the servicing employee carries the products and refills both areas (storage and extra storage). In the other, the employee does not need to carry anything to refill, making the reloading using the products already placed in the extra storage area. This new reloading possibility increases the reloading system's efficiency. That means that the servicing employees are able to refill about 30% more machines spending the same time, Opening Controlling System - The conventional vending machines are opened using a key. In the case of this invent, the door is opened using a master barcode. It brings many advantages for the machine operation. The system logs the date, the time and the employee ID each time that the machine is opened and closed. With this information, the manager can easily control the servicing employees work.
