Next, the operation of the vending machine will be described with reference to the flowchart shown in FIG. First, the customer inserts the shopping card into the insertion port 38, the insertion detector 26a outputs an insertion signal S _1, the intake control unit 34A is ordered to operate take-ejection device 27a, taking the discharge device 27a is shopping Take the card into the storage unit 25a without removing it (a, b). Then, taking the detector 28a outputs an accepting signal S _2, the first item weight reading storage unit 34B
Reads and stores the product weight W ₁ of each product from the weighing scale 22a, and the comparison means 34I reads the second product weight in advance and the product weight W ₂ and the product weight W of each previous product stored in the storage means 34D. ₁ is compared, and if the product weights W ₁ and W ₂ match, a match signal S ₃₀ is output (C, D). In this case, the receiver / transmitter control means 34C controls the transmitter 30a and the receiver 31a.
While the display is stopped, the display lamp control means 34J turns on the display lamp 39 indicating that shopping is possible to display that shopping is possible (to e). In this state, the transmitter 30a is stopped and the electromagnetic wave film is not spread on the front of the shelf main body 21a, so that the customer can freely put his hand inside the shelf main body 21a, and the customer can purchase the product. It is possible to select a product by touching. Then, when the customer takes out one or more commodities of one or more commodities from the shelf main body 21a and presses the shopping end instruction push button 24a, the receiver / transmitter control means 34C operates the transmitter 30a and the receiver 31a. At the same time, the display lamp control means 34J turns off the display lamp 39 to display that shopping is impossible (G, J,
Re). Next, the second product weight reading and storing means 34D reads and stores the product weight W ₂ of each product after taking out the product from the weighing scale 22a, and the number limiting means 34K (1) for each product,
It is determined whether or not the expressions (2) are both satisfied, and if at least one of them is not satisfied, the non-excess signal S ₄₀ is output (nu, le). In this case, the foreign matter mixture determination means
34M judges whether or not the formulas (1) and (2) are not satisfied for each product, and outputs the non-foreign substance mixing signal S ₅₀ when either one is satisfied, and at this time, the number calculation means 34E ( Integer of the one that holds among the formulas 1) and (2)
N ₁ and N ₂ are determined to be the number N, and the product number, unit price, number N, weight, etc. of the product for which the number N is not zero are stored (wo, w). Then, the writing / ejection control means 34F commands the intake / ejection device 27a and the writing device 29a to operate, and the writing device 29a
Writes the product number, unit price, number N, weight, etc. of the taken out product on the shopping card, and the intake / ejection device 27a discharges the shopping card so that the product can be taken out, and the alarm control means 34G actuates the transmitter 30a. it is judged whether or not the shutdown signal S ₆ from the receiver 31a is outputted later, if receiver 31a crisp interruption signal S ₆ is not output, the flow returns to the beginning (mosquito, Yo). Also,
When shopping card into the insertion port 38 is not inserted, it is determined whether or not the shutdown signal S ₆ from the receiver 31a output by the alarm control unit 34G, if not output interruption signal S ₆ from the receiver 31a, started Return to (a, ta). And the insertion port
In a state in which the shopping card is not inserted in 38, the electromagnetic wave transmitted from the transmitter 30a is cut off, since the shut-off signal S ₆ is outputted to the multicast controlling section 34G from WARNING receiver 31a, the warning controller 34G alarm The lamp 32a is turned on and the alarm buzzer 32b is activated to notify the staff that there has been an illegal purchase (a, ta, le). In this case, after the clerk checks whether or not an illegal purchase has been made, the lock 42 is unlocked with a key, the door 41 is opened, and the push button 33 is pushed.
G turns off the alarm lamp 32a and stops the alarm buzzer 32b (so, tsu). Also, a shopping card is inserted into the insertion slot 38,
Even if the electromagnetic wave emitted from the transmitter 30a is cut off after the transmitter 30a is activated when shopping is performed,
The same operation is performed (Yo, Le, Seo, Tsu). further,
When the product weights W ₁ and W ₂ do not match, the comparison means 34
I outputs the disagreement signal S ₃₁ , and in this case the discharge control means 34N
Instructs the intake / discharge device 27a to operate, the intake / discharge device 27a discharges the shopping card, and an alarm is issued. The rest of the operation is the same as described above (d, ne, le, se, and tsu). Further, (1), when satisfied are both (2), the number limiting means 34K outputs the excess signal S _41, an alarm is issued in this case, after the staff has stopped alarm, the pushbutton 43 When pressed, the discharge control means 34N orders the intake / discharge device 27a to operate, and the intake / discharge device 27a discharges the shopping card discharge (Le, Na, La, Mu, U, ヰ). And (1), when (2) is not both satisfied, contamination signal S ₅₁ from the contamination determination unit 34M is output, in this case an alarm is issued, when the operation after the output has exceeded signal S ₄₁ Is the same as (wo, na, la, mu, u, ヰ).

In this way, when the customer inserts the shopping card into the insertion slot 38, takes out the desired product from the shelf main body 21a, and presses the shopping end instruction push button 24a, sales information is written on the shopping card and ejected. The customer can purchase products from different vending machines one after another, and the sales information of all the products purchased by the customer is written on the shopping card. When you insert it into an electronic checkout device with, the price of all purchased products will be displayed. Then, when the shopping card is not inserted into the insertion slot 38 and the electromagnetic wave is transmitted from the transmitter 30a and the electromagnetic wave film is spread on the front surface of the shelf body 21a, the customer puts his / her hand inside the shelf body 21a. Then, when an attempt is made to take out the product, an alarm is issued, so that illegal purchase can be prevented. In addition, after the shopping card is inserted into the insertion slot 38, the transmitter 30a is stopped so that the electromagnetic wave film is not expanded, and the product weight W ₂ after the previous shopping is finished and the product weight before the current shopping is started. Product weight W ₁
Compare with, and when the product weights W ₁ and W ₂ do not match,
Since the alarm is issued, even if the product is taken out of the shelf main body 21a when the electromagnetic wave film is not spread after the store is closed, it can be found. By the way, for example, the unit weight a of a product is 10 g, and the error weight b is 1 g.
In some cases (actually, the error weight b is about 1% of the unit weight a, but the above example is taken for convenience of calculation), the number N cannot be calculated when the number N is 5 or more. There is. For example, when the number N is 5, the weight difference W is
While the weight difference W can be 45 to 55 g, the weight difference W can be 54 to 66 g when the number N is 6, so that the weight difference W is 5
When it is 4 to 55 g, that is, when the expressions (1) and (2) are both satisfied, the number N cannot be calculated. However,
In this embodiment, when the expressions (1) and (2) are both satisfied, an alarm is issued as if the limit number has been exceeded, so the number N can be calculated accurately. Further, it is conceivable that the customer may take out the product on the retainer 23 and instead place a product of a different item from the product to be held in the retainer 23 or a non-commodity product on the retainer 23. Even in this case, the number N cannot be calculated accurately. For example, when the unit weight a of the product is 100 g and the error weight b is 1 g, the customer takes out five products and places the other products on the holder 23, and as a result, the weight difference W is 240 g. If so, the number N will be 2. However, in this embodiment, an alarm is issued when the expressions (1) and (2) are not both satisfied, so that such illegal purchase can be prevented. That is, in the above example, when the number N is 2, the weight difference W is 198 to 202 g, and when the number N is 3, the weight difference W is W.
Therefore, the weight difference W is 202g <W
Since <297 g cannot be achieved, in such a case, that is, when the expressions (1) and (2) are not both satisfied, an alarm is issued as if there was an illegal purchase with a foreign substance mixed therein. Since the weight written on the package of the product is usually the net weight of the product and does not include the weight of the package, it is difficult for the customer to know the unit weight a of the product accurately. It is possible to reliably prevent such illegal purchase.

In the above embodiment, a plurality of weight scales 22a are provided in the shelf main body 21a so that one vending machine can sell a plurality of items of goods. Individual weight scales 22a may be provided. Further, in the above-described embodiment, the weight scale 22a which converts the weight into an electric signal by the piezoelectric element or the like is used as the weight scale 22, but the weight scale 22 converts the deformation amount of the spring due to the weight change into the electric signal. It is also possible to use. Further, in the above-mentioned embodiment, the alarm lamp 32a and the alarm buzzer 32b are used as the alarm device 32.
However, only one of them may be used. In addition, indicator lamps are provided to indicate that the electromagnetic wave film has been blocked, that the product weights W ₁ and W ₂ do not match, that the number N has exceeded the limit number, and that there has been an illegal purchase that contains foreign matter. May be. Also, in the above embodiment,
When the clerk presses the pushbutton 33, turns off the alarm lamp 32a, when it was stopped alarm buzzer 32b, the customer inserts the shopping card into the insertion port 38, the insertion detector 26a has output insertion signals S ₁ Alternatively, the alarm lamp 32a may be turned off and the alarm buzzer 32b may be stopped.Also, when the customer retracts his / her hand without taking out the product from the holder 23, the alarm lamp 32a is turned off and the alarm buzzer 32b is turned on. In this case, when the electromagnetic wave film is cut off, the weight of the product at that time is read and memorized when the electromagnetic wave film is cut off, and when the electromagnetic wave film is expanded again, the product at the time point is read from the weight meter 22a. It suffices to read and store the weight to determine whether or not the product weight has changed, and when the product weight has not changed, turn off the alarm lamp 32a and stop the alarm buzzer 32b.

〔The invention's effect〕

As described above, in the vending machine according to the present invention, even if a customer is shopping at a certain stage of a product shelf, another customer can shop at another stage of the product shelf. Therefore, the waiting time of the customer can be eliminated or reduced, so that the sales amount can be increased. As described above, the effect of the present invention is remarkable.
