Description

[Detailed Description of the Invention] (a) Technical field to which the invention pertains This invention provides a vending machine that dispenses goods and change according to the amount of money deposited, and returns the pooled money as is when canceling a purchase. Regarding.

(1)) Conventional technology and its disadvantages In a vending machine that can insert multiple denominations of money, for example, 1
When purchasing an item worth 0 yen, if five 100 yen coins and one 10 yen coin are inserted, 500 yen coins will be released as tsurusen. Vending machines are often used for the purpose of exchanging money.

However, if coins are exchanged frequently into higher denominations, the reserves for higher denominations will run out faster, which will increase the number of times the reserve must be replenished, leading to a problem in which the operating efficiency of the vending machine will deteriorate. .

(C) Object of the Invention The object of the invention is to provide a vending machine that can reliably prevent exchange of deposits of lower amounts.

(d) Structure and Effect of the Invention This invention pools the input money, and when the purchase is canceled, -H pools the input money.
A vending machine that returns pooled deposits as is, and includes a storage means for storing the deposited amount and the change amount by denomination, and a storage means for storing the deposit amount and the change amount by denomination, and a storage means for storing the deposit amount and the change amount by denomination, and whether the maximum denomination of the change amount is equal to or greater than the maximum denomination of the input amount. C), when the highest denomination of the change amount is equal to or higher than the highest denomination of the input amount, -J↓ returns the pooled input money as is and prohibits its sale; It is characterized by preventing exchange to a higher denomination than the deposited money.

According to this invention, the function of -H pooling the deposited money is used, and if the highest denomination of the change amount is equal to or higher than the highest denomination of the deposited amount, the deposited money is returned as is, thereby reliably preventing currency exchange. I can do it. Therefore, the reserve money can be used only for normal purchases, which has the advantage of reducing the number of times the reserve money is replenished and improving operational efficiency. Furthermore, since there is no need to prepare extra reserves for exchanging money, the reserve storage area can be made smaller, which has the advantage of not hindering the miniaturization of the vending machine.

(e) Description of the Embodiment FIG. 1 is a front view showing the front panel of the vending machine of this embodiment, and FIG. 2 is a block diagram of the control circuit of the vending machine.

The front panel of this vending machine includes a coin slot I, a bill slot 1"2, a purchase cancellation button 3, and the type of purchased item (A
-E) and manually select the type selection button 5, and select the number of purchased items and enter the number selection button 6.
, a discharge port 4 through which articles and change are discharged is provided.

This vending machine accepts banknotes and coins in the -H pool (
(not shown) and then pool them at the time of purchase transaction! - It has a pool mechanism in which the pooled input money is stored in the input money storage section according to denomination.

The control circuit of this vending machine is composed of a CPU IO as shown in FIG.

After the authenticity of the input banknotes is determined by the input banknote processing mechanism II, the input banknotes are temporarily pooled in the pool section and stored in a banknote storage section (not shown) at the time of a purchase transaction. After the denomination and its authenticity are determined by the method, the coins are once pooled in the pool section, and are stored in a coin storage section (not shown) according to denomination at the time of a purchase transaction. Purchased items are discharged from article storage units (not shown) provided for each item to the outlet 4 by the item discharge mechanism 15, and change is dispensed from reserve storage units (not shown) provided for each denomination. It is discharged into the discharge port 4 by the discharge mechanism 16 .

The type selection button 5, quantity selection button 6, and purchase cancellation button 3 are PIA (PERI PHERALI).
It is connected to CPU1 via NTERFACE ADAPTER)+4. PIAI4 is a parallel interface between CPU I and peripheral input devices. In addition, the type selection button 5 and number selection button 6 are lighted push buttons in which only the selection button corresponding to the inserted amount is lit after the loan is inserted, and when one of the lit buttons is selectively pressed. Only the button lights up.

Memo 1 connected to CPUl0. ll3g, which has the memory area shown in Figure 3. Memory areas Al to A5 are
This is an area for storing input money by denomination, that is, 10 yen, 50 yen, 100 yen, and 500 yen coins, and the number of each of the five 1000 yen bills. Memory areas A6 to A9 are areas for storing the types (A-E) of purchased items, the number 11, the price m, and the amount of change X, respectively. The maximum denomination of the change amount is stored in the memory area AIO. The input amount M and the highest denomination of the input amount are still stored in the memory areas A11 and Al1, respectively. In the memory area AI3, goods-
A price table is stored, and when any of the type selection buttons 5 is pressed, the price of the selected article is read from this table and stored in the memory area A8. Goods-
An example of a price table is shown in FIG. 3(B). The memory area AI4 is an area for storing a currency exchange prevention flag that is turned on when a currency exchange prevention switch (not shown) is pressed.

If exchange to a higher denomination is permitted, the exchange prevention switch can be turned off to enable exchange.

Next, the operation of this vending machine will be explained with reference to the flowchart shown in FIG.

Step nl (hereinafter, step old is simply referred to as n i)
When a user inserts coins or banknotes, the inserted money is classified by denomination and stored in a memory area Al.
~A5 is stored. At this time, the input amount M and the highest denomination of the input amount are stored in the memory area AI 1SA1.
2 is stored.

Then, at n2, the type selection box 5 and number selection button 6 corresponding to the input amount M are lit. Therefore, the user
If the user wishes to purchase, he or she presses either the lit type selection button 5 or number selection button 6 to input the type and number of items, and the change amount X is determined from the input information (n3, n4).

At this time, the deposited money is in a -H pooled state in the -1 pool section, and if the type selection button 5 and quantity selection button 6 are not pressed and the purchase cancellation button /3 is pressed, the deposited money is once pooled. will be returned as is. The change amount X is the input amount M, the price of the item m, and the number of items n, then X = M
−m X n. The change amount X and the maximum denomination of the change amount are stored in the memory area A9, AIO&.

Next, at n5, it is determined whether the exchange prevention switch is on or not. If exchange to a higher denomination is permitted, use n9-/nl.
Proceed to step O, and normal purchase processing is performed. Therefore, for example, five 100 yen coins and eight 10 yen coins are inserted,
If one item E is selected at n3 and there are 10, change is released using a 500 yen coin, and item E is also released.

On the other hand, if the exchange prevention switch is turned on at n5,
Proceed to the exchange prohibition process of n6-+n7=n8.

At n6, the maximum denomination of the input amount and change amount is read out. Then, at n7, it is determined whether the highest denomination of the change amount is the same or higher denomination than the highest denomination of the input amount, and if the highest denomination of the change amount is greater than or equal to the highest denomination of the input amount. Proceed to n8.

For example, in the above example of the input amount, the highest denomination of the input amount is 100 yen, but the maximum denomination of the change amount is 500 yen. Returned and prohibited from sale. On the other hand, if the highest denomination of the change amount is a lower denomination than the highest denomination of the input amount, it is judged as a normal purchase transaction, and n 7 - n 9 = n
The process moves to step l'C, and the change and purchased items are discharged. In this way, n7 constitutes a step of determining whether the maximum denomination of the change amount is equal to or greater than the maximum denomination of the input amount.

As mentioned above, in this vending machine, when it is necessary to dispense change in a higher denomination for an input money of I--th denomination, the input money that has been pooled is returned as is. Therefore, it is possible to reliably prevent exchange to higher denominations. Therefore, the reserves are not used for such exchange purposes, but only for normal sales, eliminating the need for extra reserves. Moreover, since the number of reserves to be refilled is also reduced, the operating efficiency of the vending machine is greatly improved. In addition, since the pool mechanism is used to return the deposit, there is no need to provide a separate return mechanism that prohibits exchange.Furthermore, the size of the reserve storage section can be minimized, so the vending machine Does not hinder miniaturization.
