がある。2. Description of the Related Art There are two types of vending machines: one in which merchandise can be purchased with cash, and the other in which a prepaid card is used instead of cash. In the latter vending machine,
The card inserted from the card insertion slot is taken into the card reader / writer, and the amount of money included in the card is rewritten according to the purchased product, and the card is carried out together with the product. The one using the conventional card is convenient for the user in that cash is not required, and is also advantageous in managing the vending machine. However, there is still an unsatisfactory point in that the user needs to take out the card possessed, insert it into the vending machine, and then take back the card taken out after the purchase of the product is completed.

となる。[0003] A non-contact type IC card which has a built-in integrated circuit, can extract information contained in the integrated circuit to the outside by radio, and can write information from the outside by radio is already known. If this IC card can be used in a vending machine, the user can operate the vending machine and purchase a product while holding the card without taking out the card, which is extremely convenient. However, when a non-contact type IC card is used, the condition that the IC card is always held by the user and is not temporarily held in the vending machine, and the purchase amount is determined only when the product is selected and the product is carried out, and the IC card is determined There is a condition that it is possible to settle the amount of money included in the vending machine, so it is a problem how to make an adjustment without loss to both the user and the vending machine administrator.

その釦を押すと、商品が搬出され販売動作は終了する。In the present invention, when the prices of the products handled by the vending machines are all the same and are the same, the system is switched to the first control system. When the user carrying the IC card stands in front of the vending machine and enters a product purchasing operation, the IC card control unit issues a command for subtracting the amount of the common price via the antenna from the wireless card to the IC card carried by the user. And the amount included in the IC card is rewritten to an amount reduced by a certain common price, while the information that the common price has been received from the IC card control unit is sent to the vending machine main control unit. The selection buttons for the products that can be sold, that is, all the products that are not in the sold-out state, are turned on. When the user selects a product and presses the button, the product is carried out and the selling operation ends.

When the user carrying the IC card stands in front of the vending machine and enters a product purchasing operation, the IC card control unit issues a command to temporarily remove the amount included in the IC card via the antenna in a form to temporarily store the amount. Information is sent wirelessly to the IC card, and information that the amount has been paid is sent from the IC card control unit to the vending machine main control unit. The selection buttons of all the products whose price is equal to or less than the amount of the card are lit. When the user selects a product and presses the button, the product is carried out, and the vending machine main control unit sends the difference between the deposit amount and the sold product price to the card control unit as refund information. The card controller wirelessly sends a command to return the refund amount to the IC card via the antenna, the refund amount is written on the IC card, and the selling operation ends.

売動作は終了し、制御回路は待機状態に入る。FIG. 3A shows a control circuit in the first control system used when the prices of the products handled by the vending machine are all equal. The setting device 3 of the IC card control unit 2 sets the product price (see FIG. 3). In the example, 110 yen is set. When the user carrying the IC card 11 stands and presses the set button 5 in front of the vending machine to purchase a product, the control circuit of the vending machine enters an operating state, and the IC card control section 2 sets the set price. A command to subtract 110 yen from the amount included in the IC card is transmitted wirelessly via the antenna 4 to the IC.
Send to C card 12. As a result, the contents of the IC card 12 are rewritten. For example, if the IC card 12 initially includes the amount of 1000 yen, the balance of 890 yen is written. While I
The C card control unit 2 inputs that 110 yen has been paid to the vending machine main control unit 1, whereby the vending machine main control unit 1 obtains all items except for products that can be sold, that is, those sold out. The lamp of the product selection button 8 is turned on. When the user operates the one product selection button 8,
The vending machine main controller 1 issues a carry-out signal to the commodity carry-out mechanism 10, the selected commodity is carried out to the commodity carry-out port 11, the vending operation ends, and the control circuit enters a standby state.

い。If the user wants to cancel the purchase after pressing the set button, the IC card control unit 2 operates the refund lever 9 so that the IC card control unit 2 issues a command to add the set amount of 110 yen to the antenna. 4 to the IC card 12, the remaining amount of the IC card 12 is 890 yen, 110 yen is added, and the IC card 12 is rewritten to 1000 yen, and the control circuit enters a standby state. In this case, if the user leaves without operating the refund lever 9, the user's IC card is 110
Since the circle is still subtracted, and when operating the refund lever 9, the refund operation cannot be performed smoothly unless the user is within the operation range of the antenna. It is desirable to be able to evoke.

用者の注意を喚起するようにすることが好ましい。FIG. 3B shows that the prices of the products handled by the vending machine are not equal, and that a plurality of types of prices (100 yen and 20 yen in the example in the figure) are used.
(0 yen) is a control circuit used in the second control method used in the case where there is no price set in the setter 3 of the IC card control unit 2 and is indicated by "000" in the figure. ing. When the user carrying the IC card 12 stands in front of the vending machine and presses the set button 5 to purchase a product, the control circuit of the vending machine enters an operating state, and the IC card control section 2 sets the IC card 12 Via the antenna 4 gives a command to deduct the full amount in the form of temporarily depositing the amount contained in
The data is transmitted to the card 12. As a result, the contents of the IC card 12 are rewritten, and the balance becomes 0 yen. Here, assuming that the amount initially included in the IC card 12 is 1000 yen, the IC card control unit 2
The fact that there is a deposit of 00 yen is input, and thereby the vending machine main controller 1 turns on the lamp of the product selection button 8 corresponding to the product that can be sold. When the user operates the selection button 8 of the commodity of the current price of 200 yen, the vending machine main controller 1 issues a carry-out signal to the commodity carry-out mechanism 10, and the selected commodity is carried out to the commodity carry-out port 11. Next, when the user operates the refund lever 9, the vending machine main controller 1 calculates the difference between the deposit amount and the purchase amount and sends it to the IC card controller 2 as refund information. In case of 10
A command to add 00 yen−200 yen = 800 yen is transmitted to the IC card 12 via the antenna 4, and the 800 yen refund amount is written on the IC card. Also in this case, it is preferable that the user be alerted by a lamp, a buzzer, or the like so that the user does not forget to operate the refund lever 9 and stays within the operation range of the antenna.

In this example, the IC card control unit 2 does not include a setting device, and switching between the two control systems is performed by a price setting mechanism 1 normally provided in the vending machine main control unit 1.
3 is performed. That is, the price setting mechanism 13 sets a price for each of the loaded products for each column.
The price data set in No. 3 is read and stored, and if the price is the same for all columns, the first control method is switched to the first control method, and if there is a different price, the control method is switched to the second control method. The reading of the set price data can be performed, for example, when the power is turned on or when the price is changed.
