Abstract

PURPOSE:To keep sales data before changing the price, which is composed of the three information of a setting price, sold pcs. of article and sales amount by prohibiting the change of the setting price by a setting price changing means when sales information are not zero-cleared. CONSTITUTION:When sales information I of a sales information storing means 4 are not zero-cleared and accordingly there is not output of a discriminating signal H, although a setting price changing means 6 tries to change a setting price P to a price Q, this change is prohibited and the setting price P of a setting price storing means 2 is held. In such a case, a sales data operation display means 12, which receives a setting price change requesting signal R to be outputted from the setting price changing means 6, obtains the sales data, which are composed of three data of the setting price P, sold pcs. of article N and sales amount C, based on the setting price P to be outputted from the setting price storing means 2 and the sales information I to be outputted from the sales information storing means 4. Then, these sales data are displayed. Thus, the original sales data are kept.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vending machine capable of displaying sales data consisting of a set price of a product, the number of units sold, and the total sales amount.

[Prior art and its problems] A conventional vending machine has a set price storage means for storing a set price P of a product, and a sales number N that is updated each time a product is sold.
and sales information storage means for storing the total sales amount C; a set price changing means for changing the stored set price r/lP to a desired price t'8Q; and a set price stored in the set price storage means. P, and a sales data display means for displaying the number of sold items N and the total sales amount C stored in the sales information storage means.

Each time a product is sold, the number of sold items N in the sales information storage means is incremented, and the total sales C is updated to the sum of the previous total sales and the set price P. Therefore, normally, the total sales C stored in the sales information storage means always matches the amount obtained by multiplying the set price P by the number of sales N, and this total sales Cρ (which always indicates the actual value) Ta.

However, in the past, even if the set price P was changed to Q, two pieces of information, the number of units sold and the total sales amount, were left unchanged in the sales information storage means, so after the set price was changed, the new set price Q and The product with the number of units sold no longer matched the total sales amount.

As described above, the total sales amount is no longer stored sequentially in the sales information storage means, and the amount obtained by multiplying the set price stored in the set price storage means by the number of units sold in the sales information storage means is displayed as the total sales amount. It may be possible to resolve this discrepancy, but in this case, there was a problem that if the set price was changed, the total sales amount would no longer match the actual value.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a vending machine that does not cause the above problems even when the set price is changed.

[Means for Solving the Problems] In order to achieve the above object, the present invention has the following configuration shown in FIG. 1.

That is, the set price storage means 2 stores the set price P of the product. The sales information storage means 4 stores sales information (■).

This sales information (2) consists of at least one of the number of products sold N and the total sales amount C, and these pieces of information are updated each time a product is sold. The set price changing means B outputs a set price change request signal R to the sales data calculation display means 12, which will be explained later, and also changes the set price P stored in the set price storage means 2 to a desired price t80. do. The sales information clearing means 8 outputs a clear signal U to the sales information storage means 4 to zero-clear the sales information ■ stored in the sales information storage means 4. Sales information clear determination means 10
is the sales information of this sales information storage means 4! It determines that has been cleared to zero and outputs a determination signal H. When the sales information I in the sales information storage means 4 has not been cleared to zero and therefore the determination signal H is not output, changing the set price P by the set price changing means 6 is prohibited. Further, when the determination signal H is not output and the set price change request signal R is input from the set price change means 6,
The sales data calculation and display means 12 calculates and displays sales data consisting of three data: a set price P, the number of sold items N, and the total sales amount C, based on the settings 11IIiRakuP and the sales information 1. The vending machine according to the present invention has the above configuration.

[Function] In the vending machine according to the present invention, when the sales information ■ in the sales information storage means 4 is not cleared to zero, and therefore the determination signal H is not output, the set price changing means 6 changes the set price P to Q. Even if an attempt is made to change the price, the change is prohibited and the set price P in the set price storage means 2 is held. In this case, the sales data calculation and display means 12 that receives the set price change request signal R output from the set price change means B outputs the set price P output from the set price storage means 2 and the sales information storage means 4. Based on the sales information I, sales data consisting of the set price P, the number of sold items N, and the total sales amount C is obtained and displayed. This saves the original sales data.

In this state, when the sales information clearing means 8 outputs the clear signal U, the sales information l in the sales information storage means 4 is cleared to zero. When the sales information (■) is cleared to zero, the sales information clear determination means 10 outputs a determination signal H, and the prohibition of changing the stored contents of the set price storage means 2 is canceled.

Therefore, the set price changing means 6 changes the set price P in the set price storage means 2 to the desired new price Q.

[Embodiment] FIG. 2 is a block diagram of a vending machine according to an embodiment of the present invention.

Reference numeral 20 denotes an operation box usually arranged on the back side of the door of a vending machine, and has an LCD display 22, a numeric keypad 24, a clear key 26, a price setting key 28, a sales confirmation key 30, and a buzzer 32. This operation box 20 is connected to a microprocessor 36 via an input/output port 34, and a memory 38 is connected to this microprocessor 36. The memory 38 is a non-volatile RAM backed up by a battery, and the set price P1 of the product is stored in this memory.
The number of sold items N and the total sales amount C are stored.

The memory 38 functions as the set price storage means 2 and the sales information storage means 4. However, in this embodiment, two pieces of information, the number of sold items N and the total sales amount C, constitute the sales information I. Each part of the operation box 20 exchanges signals with the microprocessor 3B through the input/output board 34. Of these, the ≠receiver key 24 and the price setting key 28 function as the set price changing means 6, and the numeric keypad 24 is used to input a new set price, while the price setting key 28 requests the microprocessor 3G to change the price setting. give a signal.

The clear key 26 is used as sales information clearing means 8. The microprocessor 3B is not only used as the sales information clear determination means 10, but also functions together with the LCD display 22 as the sales data calculation and display means 12. The buzzer 32 is provided to prompt the operator to clear the sales information l to zero, and the sales confirmation key 80 is used to display the set price P1, number of sales N, and total sales C, as in the past.
Used for confirmation.

Next, the operation of the vending machine having the above configuration will be explained based on the flowchart of FIG. 3 showing the operation of the microprocessor 36. In addition, by other processing not shown in the figure, the number of sold items N in the memory 38 is incremented each time a product is sold, and the total sales amount C is increased each time, as in the conventional case.
is updated to the previous total sales amount plus the set price P.

Therefore, the total sales C stored in the memory 38 always matches the amount obtained by multiplying the set price P by the number of sales N, and moreover, the total sales C always indicates the actual value.

When the processing procedure reaches step 1, it is checked whether the price setting key 28 of the operation box 20 has been pressed. If the price setting key 28 is not pressed, step 1
1, but if the price setting key 28 is pressed in an attempt to change the set price P in the memory 38, the process proceeds to step 2. In step 2, it is checked whether the number of sold items N and the total sales amount C stored in the memory 38 are both zero. If these pieces of information have already been cleared to zero, jump to step 7 and immediately change the set price P, but if they have not been cleared to zero, proceed to step 3.
Then, the buzzer 32 is sounded to call the operator's attention.

Next, in step 4, the set price P1, the number of units sold, N, and the total sales amount C stored in the memory 38 are displayed on the LCD display 22 to notify the current sales data, and the words "Please clear 5" are displayed on the LCD display 22. It is displayed on the display to encourage clearing of the sales quantity N and sales total C. After recording the displayed sales data, the operator presses the clear key 26. The microprocessor 3B waits for the clear key 26 to be pressed in step 5, and then proceeds to step 6, where it clears the sales number N and total sales C to zero. Once the sales information has been cleared to zero as described above, the process proceeds to step 7, as in the case where it is found in step 2 that the sales information has already been cleared to zero.

In step 7, the words "Please set price" are displayed on the LCD display 22 to prompt the user to input a new set price. In response to this, the operator inputs a new set price Q through the numeric keypad 24 in step 8, and the set price P in the memory 38 is rewritten to Q in step 9. After erasing the display on the LCD display 22 in step 10, the process proceeds to step 11.

Steps 11 to 16 indicate normal operations other than changing the set price. That is, when the sales confirmation key 11 is pressed, in steps 11 to 14, the set price P1, number of sales N, and total sales C are displayed on the LCD display 22 until this key is pressed again, and the operator confirms this. be able to.

Also, at any time such as after collecting the input money, step 15
- 16, the number of sold items N and the total sales amount C can also be cleared to zero by pressing the clear key 2B.

When the process of step 16 is completed, the microprocessor 36 again executes other processes. Note that the operations of steps 1 to 16 described above are repeatedly executed at appropriate time intervals.

FIG. 4 is a block diagram of a vending machine according to another embodiment of the present invention.

In this embodiment, the operation box 20 has a printer 40 instead of the LCD display 22. The clear key 26 and the price setting key 2B each have a light emitting display section made of an LED. Reference numeral 42 indicates a clear LED, and reference numeral 44 indicates a pricing LED. The memory 38 also stores the total sales C
is not stored, but only the set price P and the number of units sold N are stored. Since the components other than those described above are the same as those in the previous embodiment, the explanation thereof will be omitted. In this embodiment, only the sales number N constitutes the sales information I, and the sales data calculation and display means 12 is constituted by the microprocessor 3G and the printer 40.

FIG. 5 is a flowchart showing the operation of the microprocessor 36 of FIG. Note that the number of sold items N in the memory 38 is incremented each time a product is sold by other processing not shown in the figure.

When the processing procedure reaches step 21, the operation box 2
It is checked whether the price setting key 2B of 0 has been pressed. If the price setting key 2B is not pressed, the process jumps to step 34, but if the price setting key 28 is pressed in an attempt to change the set price P in the memory 38, the process proceeds to step 22.

In step 22, it is checked whether the number of sold items N stored in the memory 38 is zero. If this has already been cleared to zero, the process jumps to step 30 and the set price P is changed immediately, but if it has not been cleared to zero, the process proceeds to step 23 and the buzzer 32 sounds to alert the operator. evoke.

Next, in step 24, the product of the set price P stored in the memory 38 and the number of sold items N is calculated, and this product is set as the total sales amount C. In step 25, the set price P of the memory 38 is
, the number of sold items N, and the total sales amount C determined by calculation are outputted to the printer 40 to print sales data consisting of these pieces of information. In this embodiment, since the sales data is printed, the record is automatically kept. Step 2
At step 6, the clear LED 42 is turned on to prompt clearing of the sales number N. After this lighting, the microprocessor 3B
After waiting for the clear key 28 to be pressed in step 27 and clearing the sales number N to zero in step 28, the clear LED 42 is turned off in step 29. Once the sales information is cleared to zero as described above, step 2
In the same way as in step 2 where it is found that this has already been cleared to zero, proceed to step 30.

In step 30, the price setting LED 44 is turned on to prompt input of a new set price. In response to this, the operator inputs a new set price Q through the numeric keypad 24 in step 31, and the set price P in the memory 3B is rewritten to Q in step 32. After turning off the price setting LED 44 in step 33, the process proceeds to step 34.

In steps 34 to 36, each time the sales confirmation key 11 is pressed, the total sales amount C is calculated similarly to step 24, and the set price r6p is sent to the printer 40.

Print the sales quantity N and total sales amount C. Furthermore, the sales number N can be cleared to zero by pressing the clear key 26 in steps 37 and 38.

When the process of step 38 is completed, the microprocessor 36 again executes other processes. Note that the operations of steps 21 to 38 described above are also repeatedly executed at appropriate time intervals.

Note that the memory 38 stores two values: the set price P and the total sales C.
Only information may be stored.

However, in this case, the total sales C is the original set price P.
The value divided by N is displayed as the number of products sold.

[Effects of the Invention] In the vending machine according to the present invention, even if an attempt is made to change the set price before the sales information has been cleared to zero, this change is prohibited, and the change is prohibited between the set price, the number of units sold, and the total sales amount. The sales data before the change consisting of information is displayed,
This data will be saved. In the displayed sales data, the total sales amount always matches the product of the set price and the number of units sold, and this total sales amount matches the actual value.

After the sales information is cleared to zero, the set price can be changed to a desired new price in the same way as before. Moreover,
Since the sales information is cleared to zero at the same time as the set price is changed, the normal relationship between the stored contents of the set price and sales information will not be disrupted after this change.
