Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product sales data processing device that performs product registration processing using a scale and a code scanner.

[Conventional technology]

2. Description of the Related Art Conventionally, as a product sales data processing device that uses a code scanner to read and register a code attached to a product, for example, the device disclosed in Japanese Patent Application Laid-open No. 76468/1983 is known. In other words, the method in this publication sequentially registers each product stored in a container by reading the code attached to the product with a code scanner, and finally registers the product according to the total key attached to the container. The code is read with a code scanner and the total registration is displayed.

[Problems to be Solved by the Invention] However, this conventional device displays the total by using a code scanner to read the code attached to the container, so the operation for displaying the total is troublesome. .

In addition, if customers are asked to register products, it will not be possible to detect fraud in which each customer does not allow the product to be read by a code scanner. I couldn't do it in service.

Therefore, the present invention can automatically process the registration totals when product registration is performed by reading them with a code scanner, thereby eliminating the need for troublesome totalization operations, and also allowing each customer to perform product registration operations through self-service. The present invention aims to provide a product sales data processing device that can perform the following tasks.

[Means to solve the problem]

The present invention includes a first scale that collectively weighs a plurality of products purchased by a customer, a scale initial memory that stores the first measured value of the first scale, and a scale initial memory that stores the measured value of the first scale. A first scale instruction value memory, a code scanner that reads a product code pre-attached to the product being weighed with the first scale, and a second scale that places the product whose product code has been read by the code scanner. a scale, and a second scale that stores the measured values of this second scale.
A scale instruction value memory, a first scale change amount memory that stores the amount of change when the contents of the first scale instruction value memory changes, and a change amount when the contents of the second scale instruction value memory change. A second scale change amount memory stores the amount, and the contents of the first scale change amount memory and the second scale change amount memory are compared, and when the contents match, the code scanner reads the contents. a single item registration processing means for reading out a preset unit price from a predetermined area of the memory based on the received product code and accumulating the unit price in a predetermined area of the memory as the sales amount of the product; a display; and a scale instruction value memory. and a total display means that compares the contents with the contents of the scale initial memory, determines that the single item registration is complete when the two contents match, and displays on the display the total sales amount accumulated by the single item registration processing means. It is.

[Effect]

In the present invention having such a configuration, all products purchased by the customer are placed on the first scale. As a result, the measured value of the first scale is stored in the scale initial memory and the first scale instruction value memory. If one product is taken from the first scale in this state, the measured value of the first scale changes and the contents of the first scale instruction value memory also change. Then, the weight change amount is stored in the first scale change amount memory. Note that the contents of the scale initial memory do not change.

Items removed from the first scale are transferred to the second scale after their item code is read by a code scanner.
be placed on the scale. The measured value of the second scale is then stored in the second scale instruction value memory. In this way, the contents of the second scale instruction value memory change. The weight change amount is then stored in the second scale change amount memory.

When the above processing is completed, the contents of the first scale change amount memory and the contents of the second scale change amount memory are compared, and the product that was being weighed on the first scale is reliably placed on the second scale. Sometimes, both amounts of change match, so based on the product code read by the code scanner for the first time, the unit price of the product is read from a predetermined area of the memory, and that unit price is accumulated in the predetermined area of the memory as the sales amount. Ru.

In this way, the registration operation for one product is completed. The above registration operation will be performed for all products listed on the first scale.

In this way, when all the products on the first scale are transferred to the second scale, the measured value in the scale initial memory and the measured value in the scale instruction value memory match, so the total price of the products is cumulatively displayed on the display. It turns out.

Connected. The CPU 6 also has a printer/drawer interface 14, a display interface 15, and a keyboard interface 1.
6 are connected via the data bus line 10 and control line 11. The printer/drawer interface 14 controls the output of print data to a printer 17 that prints on receipts and journals, and also controls the opening of the drawer 18. The display interface 15 controls the output of display data to the display 19. The keyboard interface 16 controls the input of key signals from the keyboard 20. The CPU 6 is the ROM
Based on the program data stored in the RAM 8, each interface 12, 13,
14, 15, and 16, respectively.

As shown in FIG. 3, the RAM 8 stores a product code area M ₁ that stores a product code assigned in advance to each product, a product name area M ₂ that stores the name of each product, and a unit price of each product. unit price area
a single item registration memory 81 consisting of M ₃ , a sales point area M ₄ for accumulating the number of sales of each product, and a sales amount area M ₅ for accumulating the sales amount of each product;
A first scale indication value memory 82 stores the measurement value obtained by weighing with the scale 2, and a second scale indication value memory 82 stores the measurement value obtained by weighing with the second scale 3. memory 83,
A first scale change amount memory 84 that stores the amount of change in the measured value on the first scale 2, a second scale change amount memory 85 that stores the amount of change in the measured value on the second scale 3, and the code. A scanning data memory 86 that stores the product code read by the scanner 4, a scale initial memory 87 that stores the first weighed value by the first scale 2, a work memory 88, a cash totalizer 89, etc. It is provided.

As shown in FIG. 4, the keyboard 20 has replacement keys K ₁ for "00", "0", "1" to "9", a PLU key K ₂ for registering single items, a clear key K ₃ for registering single items. A current total key K ₄ for displaying the total, a subtotal key K ₅ for displaying the total, a change key K ₆ for exchanging money, etc. are provided.

The CPU 6 performs the control shown in FIG. 5 based on the program data of the ROM 7. That is, when all the products purchased by the customer are placed on the first scale 2, the measured values are taken from the first scale 2 and stored in the first scale instruction value memory 82. In this case, when the product is placed in a basket, the weight of the basket is subtracted from the weighing value. Subsequently, the contents of the first scale instruction value memory 82 are also stored in the scale initial memory 87 and work memory 88 . Further, the measured value is taken in from the second scale 3 and stored in the second scale instruction value memory 83. At this time, the measured value is zero. In this state, the measured value of the first scale 2 is stored in the first scale indicated value memory 8.
2, it is checked whether the contents of the first scale instruction value memory 82 are different from the contents of the work memory 88. In other words, this will check to see if one item is taken from the first scale 2. When the contents of the first scale instruction value memory 82 become different from the contents of the work memory 88, the contents of the first scale instruction value memory 82 are subtracted from the contents of the work memory 88 to find the amount of change in the measured value. The amount of change is stored in the first scale change amount memory 84. Subsequently, the contents of the second scale instruction value memory 83 are stored in the work memory 88. In this state, it is checked whether or not the product code has been read by the code scanner 4, and when the product code has been read, the read product code is stored in the scanning data memory 8.
6. In this state, while repeating the process of storing the measured value of the second scale 3 in the second scale instruction value memory 83, it is checked whether the contents of the second scale instruction value memory 83 are different from the contents of the work memory 88. In other words, this checks to see if the product that has been scanned is placed on the second scale 2. When the contents of the second scale instruction value memory 83 become different from the contents of the work memory 88, the contents of the second scale instruction value memory 83 are subtracted from the contents of the work memory 88 to find the amount of change in the measured value. The amount of change is stored in the second scale change amount memory 85. Then, the contents of the first scale change amount memory 84 and the contents of the second scale change amount memory 85 are compared, and if the contents do not match, the scanned product is not placed correctly and another product is placed. If so, handle the error. In this error handling, the cashier may be notified by means of a lamp, buzzer, or the like. This error processing can be canceled by operating the clear key _K3 on the keyboard 20.

Further, when the contents of the first scale change amount memory 84 and the contents of the second scale change amount memory 85 match, the scanning data memory 84
Search the single product registration memory 81 using the product code stored in , and obtain the unit price and sales number from the unit price area M ₃ , sales number area M ₄ , and sales amount area M ₅ of the memory where the corresponding product code is stored. , call up the sales amount data and add 1 to the sales score
Then, add the unit price to the sales amount to obtain a new sales amount, and add the updated sales points and sales amount to the sales points area M ₄ ,
Each product is stored in the sales amount area _M5 and registration processing for one product is performed. (Single item registration processing means) Next, the contents of the second scale instruction value memory 83 and the contents of the scale initial memory 87 are compared, and unless the two contents match, it is determined that scanning of the product has not been completed. Then, the process returns to the process of storing the contents of the first scale instruction value memory 82 in the work memory 88, and prepares for the scanning operation for the next product.

Further, when the contents of the second scale instruction value memory 83 and the contents of the scale initial memory 87 match, it is determined that the scanning operation by the customer has been completed for all products, and the display 19 displays all the products purchased by the customer. Display the total amount. (Total Display Means) Thereafter, when the cash total key _K4 of the keyboard 20 is input, the total amount is accumulated in the cash totalizer 89, and the printer 17 is driven to issue a receipt.

In this embodiment with such a configuration, all products purchased by the customer are placed on the first scale 2. Thereby, the measured value of this scale 2 is stored in the scale initial memory 87 and the first scale instruction value memory 82, respectively. Thereafter, the contents of the scale initial memory 87 are held as they are until, for example, the current total key _K4 is input.

In this state, one product is picked up from the first scale 2, the product code attached to the product is read by the code scanner 4, and then placed on the second scale 3. At this time, the measured value of the first scale 2 changes, and the contents of the first scale instruction value memory 82 also change. Then, the amount of change in the measured value is stored in the first scale change amount memory 84. Further, when a product is placed on the second scale 3, the measured value of the second scale 3 changes, and the contents of the second scale instruction value memory 83 also change. Then, the amount of change in the measured value is stored in the second scale change amount memory 85.

Since the contents of the first scale change amount memory 84 and the contents of the second scale change amount memory 85 match, the product name and unit price are read from the single product registration memory 81 based on the product code read by the code scanner 4. The unit price is accumulated as the sales amount in the corresponding sales amount area _M5 , and +1 is also accumulated in the sales points area _M4 .

In this way, registration for one product is completed.

At this time, the first scale change amount memory 84
If the contents of the second scale change amount memory 85 do not match, the product is correctly placed on the first scale 2.
It is determined that the data has not been transferred to the second scale 3, that is, there has been an irregularity, and an error is generated. In other words, registration is prohibited.

In this way, when registration is completed for all products listed on the first scale 2, the first scale 2
All products have been moved to the second scale 3. As a result, the contents of the scale initial memory 87 and the contents of the second scale instruction value memory 83 match, and the total amount paid by the customer is displayed on the display 19.

The customer then makes the payment and the cashier receives the money and operates the cash key _K4 . This completes the registration for one customer and issues a receipt.

In this way, since the total display is automatically performed when all the products on the first scale 2 are transferred to the second scale 3, key operations for displaying the total are not required, making the operation simple.

In addition, whether or not the product placed on the first scale 2 has been reliably transferred to the second scale 3 can be determined based on the amount of change in the measured value of the first scale 2 and the amount of change in the measured value of the second scale 3. Therefore, only when it is determined that the product code has been transferred correctly, the product can be registered based on the product code read by the code scanner 4. Therefore, countermeasures against fraud etc. are taken, and therefore the first scale 2 The first step is to place the product on the
The customer can self-service the registration operation, which consists of reading the product on scale 2 with the code scanner 4 and then placing it on the second scale 3. In this way, the cashier only has to receive the money and issue a receipt by operating the cash key _K4 , thereby making it possible to reduce the cashier's workload.

Although the above embodiment describes the case where the present invention is applied to a single electronic cash register, the present invention is not necessarily limited to this. For example, if a plurality of electronic cash registers are used as POS terminals, and each of the electronic cash registers is used as a POS terminal, It can also be applied to a so-called POS system in which the transaction register is controlled by a terminal controller having a file memory, and in this case, a single item registration memory may be provided in the file memory of the terminal controller.

〔Effect of the invention〕

As described in detail above, according to the present invention, when product registration is performed by reading a code scanner, the registration totaling process can be automatically performed, thereby eliminating the need for troublesome totalizing operations. It is possible to provide a product sales data processing device that allows customers to perform self-service.
