Description

[Detailed Description of the Invention] [Technical Field of the Invention J Is this invention applicable to one or more devices? ! The present invention relates to a product sales data processing system that registers and processes product sales data using several electronic cash registers.

[Technical background of the invention and its problems] Conventionally, in a product sales data processing system, the cashier operates keys or uses a code scanner to read the product code attached to the product. Registered sales data.

Therefore, conventionally, the cashier always performs the input operation for registration, which has the disadvantage of increasing the workload of the cashier. For this reason, it is conceivable to have the customer read the product code using a code scanner 17, for example. However, in this case, the cashier will not be able to read the product code with the code scanner. There is a problem in that it is necessary to check when the reading operation will be completed and display the total amount when looking at the page, which can be troublesome.

[Purpose of the invention] This invention was made to solve such problems, and it is possible to reduce the workload of the cashier, and moreover, it is possible to automatically display the total amount at the end of the single item registration operation. The purpose of the present invention is to provide a product sales data processing system that can perform the following tasks.

[Summary of the Invention] The present invention includes first and second scales for measuring the weight of a product, and a code scanner for reading a product code attached to the product in advance, and the measured value by the first scale is read by the first scale. At the same time, the measured value from the second scale is stored in the second scale indication value memory, and the first content stored in the first scale indication value memory is also stored in the scale initial memory. The preset unit price is read out in response to the input of the product code by the code scanner, and the unit price is registered as the sales amount of the product, and the contents of the second scale instruction value memory and the scale initial memory are stored. When the two contents match, it is determined that the single item registration operation is complete and the total price is displayed on the display.

[Embodiments of the Invention] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this embodiment, the present invention will be described as applied to a single electronic cash register.

The CPU 6 performs the control shown in FIG. 5 based on the program data in the ROM 7.

That is, when all the products purchased by the customer are placed on the first scale 2, the measured values are sloped 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, while repeating the process of storing the measured value of the first scale 2 in the first scale instruction value memory 82', it is checked whether the contents of the first scale instruction value memory 82 are different from the contents of the work memory 88. do.

That is, this will check whether 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 code scanner 4 has read the product code, and if the code has been read, the read product code is stored in the scanning data memory 86. In this state, the measured value of the second scale 3 is
While repeating the process of storing 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. That is,
This is to check that 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 second scale instruction value memory 83 is changed from the contents of the work memory 88.
The amount of change in the measured value is obtained by subtracting the contents of the scale instruction value memory 83, and the amount of change is stored in the second scale change amount memory 85.

Then, the contents of the first scale change memory 84 and the contents of the second scale change memory 85 are compared, and if the two contents do not match, the scanned product is placed correctly and another product is placed on the chair. If so, handle the error. In this error handling, the cashier may be notified by a lamp or a buzzer. To cancel this error process, press 3 on the clear key on the keyboard 2o.
All you have to do is operate. The first scale change amount memory 8
When the contents of 4 and the contents of the second scale change amount memory 85 match, the single item registration memory 81 is searched by the product code stored in the scanning data memory 86, and the memory in which the corresponding product code is stored is searched. Recall unit price, sales number, and sales amount data from unit price area M3, sales number area M4, and sales amount area M5,
Add 1 to the sales points to make a new sales point, add the unit price to the sales amount to make a new sales amount, and store the updated sales points and sales amount in the sales points area M4 and sales amount area M5, respectively. registration process for one product. Next, the second scale instruction value memory 83
The contents of the first scale instruction value memory 87 are compared with the contents of the scale initial memory 87, and unless the two contents match, it is determined that scanning of the product has not been completed, and the process is performed by comparing the contents of the first scale instruction value memory 82 described above. The process returns to the process of storing in the work memory 88 and prepares for the next product scanning operation.

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 customer's scanning operation has been completed for all products, and the display 19 displays a list of all the products purchased by the customer. Display the total amount. After this, when the cash key of the keyboard 20 has the 4th key input, the total amount is accumulated in the cash totalizer 89, and the printer 17 is driven to issue a receipt.

In the device according to the embodiment of the present invention configured in this manner, single item registration processing can be performed by reading the product code attached to the product with code scan=4, and there is no need to operate any keys on the keyboard 20. , the registration operation becomes easy. Moreover, since the customer performs the operation of reading the product with the code scanner 4, the workload of the cashier can be reduced. In addition, the weighing value when all products are placed on the first scale 2 is stored in the scale initial memory 87 when the customer completes the product code reading operation. Since the judgment is made based on the fact that the measured value of the scale 3 of No. 2 matches the contents of the scale initial memory 87, there is no need for the cashier to have to go through the trouble of watching the customer's scanning operation and confirming the completion.

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, each cash register can be used as a POS terminal. The present invention can also be applied to a so-called POS system 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.

[Effects of the Invention] As detailed above, according to the present invention, the workload of the cashier can be reduced, and the total price can be automatically displayed upon completion of the single item registration operation. A data processing system can be provided.
