Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a price setting device for an automatic vending machine, which sets a selling price of a product in a semiconductor storage means.

(B) Prior Art An automatic vending machine for setting a selling price of a product in a semiconductor memory means is disclosed in Japanese Patent Laid-Open No. 53-29197. In this prior art, the selling price set in the price setting device is set in the storage unit of the corresponding memory by operating the product selection switch. However, the method of setting the selling price in the storage means has a drawback that the presence or absence of the price setting cannot be visually confirmed unlike the conventional method of setting the price by the switch device (for example, Japanese Patent Publication No. 58-45752).

(C) Problems to be solved by the invention By the way, when a new vending machine is newly installed, whether the selling price has already been set at the time of manufacturing at the factory or after the factory shipment, If they are priced, you need to see what columns are priced and how much they are sold. However, since the vending machine that sets the selling price in the storage means cannot be easily confirmed due to the above-mentioned drawbacks, it has been confirmed whether the product is sold by actually inserting money to perform the selling operation.

In addition, even in the vending machine after installation, if you are using a storage means such as RAM that requires power backup,
The selling price set by the power shutdown is lost. However, when the power is restored, the manager of the vending machine will not notice the disappearance of the selling price unless he / she knows that there is a power failure.

From the above point of view, the present invention provides an automatic vending machine capable of displaying columns not priced and columns priced by price.

(D) Means for Solving Problems In order to solve the above problems, the present invention compares the input amount of money calculated by the sellable product detecting means with the selling price of the product, and sells based on this comparison. In the vending machine having a sales operation mode in which the sale possibility is displayed for each product by the sale enable display unit and the selected product is sold by operating the selection switch for the sellable product, Mode switching means for switching between the operation mode and the price setting mode for setting the selling price, the price inputting means for inputting the selling price to be set, and the selling price storing means for each product type in which the selling price is set. And an amount storage means for storing an input price from the price input means, and a price setting control means operating in a price setting mode, the price setting control means comprising: When the contents stored in the amount storage means and the storage contents stored in the sales price storage means for each product match, a means for controlling the sellable display means so as to display the product type, A unit for loading the set sales price data input from the price input unit into the amount storage unit and a set sales price data stored in the amount storage unit by operating the selection switch correspond to the selection switch. And a means for loading the selling price of the product into the selling price storage means.

(E) Action In the price setting mode, it is possible to sell when the content of the set price storage means that stores the input price from the price input means matches the content of the sale price storage means for each product type for which the sale price is set. By the display operation of the display means, it is possible to display the presence / absence of price setting and the columns for which price setting is performed by price.

(F) Embodiment FIG. 1 is a block diagram showing a circuit configuration of a vending machine according to the present invention. (1) is a mode switching means for switching the vending machine between a sales operation mode and a price setting mode,
(2) is sales control means that operates in the sales operation mode,
(3) is price setting control means that operates in the price setting mode,
(4) is a product selection means provided with a selection switch corresponding to each sale product, (5) is a price input means for inputting a selling price to be set in the price setting mode, and (6) is an input currency for each currency type. The calculating means calculates the amount of money to be input based on the signal C and also calculates the remaining amount after sale. Then, in the price setting mode, the set selling price from the price inputting means (5) is introduced into the calculating means (6). Further, (7A) is a selling price storage means having a selling price storage area corresponding to each sale product, and (7B) is an amount storage means for storing the input amount or change amount calculated by the calculating means (6), In the price setting mode, the amount storage means (7B) stores the set selling price. And (8) is a sellable product detecting means for comparing the selling price stored in the selling price storage means (7A) with the amount stored in the amount storage means (7B), and (9) is selling for each product Sellable display means for displaying the possibility of
(10) is an amount payout control means for controlling the payout of the amount stored in the amount storage means (7B) by a control signal from the sales control means (2).

When the selling operation mode is designated by the mode switching means (1) with such a configuration, the selling control means (2) operates. Then, the calculation means (6) calculates the amount of money to be inserted by the money signal C that is generated by the insertion of money and introduces it into the amount storage means (7B). Further, the sellable product detection means (8) is a storage means (7B).
Is compared with the selling price of each product set in the storage means (7A), and the sellable product is judged according to the change and the presence or absence of the product. Displays products that can be sold according to the judgment. On the other hand, when the product to be purchased is designated by the product selection means (4), the sales control means (2) determines whether the selected product is a sellable product detected by the sellable product detection means (8). If it is determined that the product can be sold, the sales drive means (11) is operated to sell the selected product. The calculation means (6) reads the selling price of the product specified by the product selection means (4) from the storage means (7A), and also reads the input amount from the storage means (7B) to calculate the change amount. Introduced in the storage means (7B), if the change amount is other than "0" yen, change change control means (1
0) controls the payout of the change amount.

When the price setting mode is designated by the mode switching means (1), the price setting control means (3) operates. In the price setting mode, the sellable product detection means (8) compares the contents of the storage means (7B) with the contents of the storage means (7A) to detect the matching product type, and the sellable display means (9). ) Displays this item. At this time, the sellable product detection means (8) is stored in the storage means (7
Even when the contents of A) and (7B) are both "0", a coincidence output is generated and the sale enable display means (9) displays it. Therefore, when the content of the storage means (7A) is "0" due to the initial operation after the power is turned on, the sale price display means (9) displays the selling price setting.

Then, when the selling price to be set is introduced from the price inputting means (5), the calculating means (6) introduces it into the storing means (7B). The price input means (5) is composed of a conventionally known input device such as a numeric keypad or a setting switch using a binary code, but the price input means (5) can also be input by inserting money for the selling price to be set. In this case, the arithmetic unit (6) introduces the input amount calculated by the input currency signal C into the storage means (7B) as the set selling price. When the set selling price is stored in the storage means (7B) in this way, the contents of the storage means (7A) do not match because they are "0" yen, so that the output of the salable item detection means (8) stops. The display means (9) for sale is no longer displayed. Next, when the selection switch of the product selection means (4) is operated to specify the product to be priced, the price setting control means (3) is stored in the storage means (7B).
While reading the set selling price, the setting selling price is written by addressing the selling price storage area of the storage means (7A) for the designated product type. In this way, the selling price to be set is input to the price input means (8), and the product selection means (4)
When the product to be priced is specified in, the selling price is set in the storage means (7A). Then, when the set selling price in the storage means (7B) is set in the storage means (7A), a match is again detected by the salable product detection means (8), and the detection means (8) indicates the matched product type. The saleable display means (9) displays this product in order to output a coincidence signal regarding. Therefore, the sellable product detection means (8) detects a product for which the selling price entered in the price input means (5) is set, and the selling price is displayed by displaying the product on the sellable display means (9). You can check the set products.

FIG. 2 shows an embodiment in which the price setting according to the present invention is achieved by the microcomputer (14), and L _{1 to} Ln

Therefore, when the up key (15) or the down key (16) is operated according to the selling price to be set, the selling price is stored in the register R _S as detected by the input detection flow by the timer interruption each time. N ₆
Timer is subtracted by subtracting the timer counter TC at step, returns to N ₀ Step When it is confirmed the completion of the timer operation by the contents of the timer counter TC at N ₇ step unfinished. Also, within the timer operating period, the selection switches S _{1 to} Sn
Alternatively, when the up key (15) or the down key (16) is operated, the timer operation is updated in the input detection flow to extend the price setting mode. Te register
When the selling price is stored in R _S and N ₁ steps are reached, no matching is detected in all the selling price storage areas M _{1 to} Mn because it is “0”, and N ₃ steps are performed. Therefore, when the set selling price is stored in the register R ₅ by the price inputting means (5), all of the available sale indicators L _{1 to} Ln are turned off.

By the way, if the selection switch S ₂ is operated and the selection switch flag FS ₂ is set in the register R ₂ in the input detection flow by the timer interruption, the pricing control flow is N
_{From 3} steps to N ₄ steps, the selling price stored in the register R _S is written in the selling price storage area M ₂ of the memory (13) corresponding to the product of the selection switch S ₂ . And N ₅
Reset the selection switch flag register R ₂ in step, further N ₆ when steps · N ₇ steps becomes N ₁ step, sales are stored in the register R _S price and the memory (1

Since the selling price is written in the selling price storage area M ₂ of the memory (2) and R _S = M ₂ , the sale possible display L ₂ is turned on and the selling price set is displayed in the N ₂ step. When setting the selling price stored in the register R _S for multiple product types, each time the corresponding selection switch S _{1 to} Sn is operated, the selection switch flag FS is detected at step n _{0 of the} input detection flow. _{1 to} FSn are set, the selling price is set in the selling price storage area M ₁ ... Mn in the N ₄ step of the pricing control flow, the selection switch flag is reset in the N ₅ step, and the register R _S is set in the N ₁ step. Detects the product set with the selling price stored in the store, and in the N ₂ step, all the sellable indicators L _{1 to} Ln corresponding to the product are detected.
Lights up. When a new selling price is input to the price input means (5), the selling price stored in the register R _S does not match the contents of any of the storage areas M _{1 to} Mn. All _{1 to} Ln are turned off. However, when the product for which the selling price is set is specified by operating the selection switch, the selling price is written in the corresponding storage areas M _{1 to} Mn, and the corresponding sale-permitted indicators L _{1 to} Ln are lit.

When Thus the contents of the timer counter TC at N ₇ step detects that becomes "0", the timer operation is completed
At the N _8th step, the price setting flag FP of the register R ₀ is reset, and at the N _9th step, the selling price of the register R _S is cleared and the price setting control flow ends. On the other hand, if the changeover switch (12) is operated again during the timer operation period, the operation of the changeover switch (12) is detected at step n ₃ of the input detection flow by the timer interrupt. In this case, the price setting flag is set.
For FP is set to the register R _0, the register R ₀ at n ₆ steps register R _S is cleared while being reset. And when returning to the pricing control flow,
When the price setting flag FP is reset, the process exits the N ₀ step and ends the price setting control flow. That is, the price setting is released by the second operation of the changeover switch (12) within the timer operation period.

(G) Effect of the Invention According to the present invention, in the vending machine that sets the selling price of the product in the semiconductor storage means, it is possible to confirm the presence or absence of the setting of the selling price by the sale enable display means.

If the sellable display means is displaying without inputting the price from the price input means, it can be determined that the sale price is not set in the corresponding sale price storage means, and the price can be determined. When the selling price is entered in the input means, the sale available display means corresponding to the selling price storage means which has not been entered is no longer displayed, and the selling price is sold by operating the corresponding selection switch. Since the price is stored in the price storage means and is displayed again by the sellable display means, it can be confirmed that the selling price has been set.
