Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a product sales data processing system for registering product sales data using one or more electronic cash registers.

[Technical background of the invention and its problems] Conventionally, in a product sales data processing system, the cashier operates a key 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, for example, but if this is done, the cashier will have to monitor the customer to make sure that they do not commit fraud. Therefore, there is a problem that they are unable to leave their seats and feel like they are in charge of the work.

[Purpose of the Invention] This invention was made to solve these problems, and provides a product sales system that can reduce the cashier's workload and that can reliably prevent customer fraud without the cashier's supervision. The purpose is to provide a data processing system.

[Summary of the Invention] This invention includes first and second scales for measuring the weight of products, a code scanner for reading a product code attached to the product in advance, and a method for determining the unique weight of each product in advance. A set product weight memory is provided, the measured value by the first scale is stored in the first scale indicated value memory, the measured value by the second scale is stored in the second scale indicated value memory, and the measured value by the second scale is stored in the second scale indicated value memory. When the contents of the first scale instruction value memory change, the amount of change is stored in the first scale change amount memory, and when the contents of the second scale instruction value memory change, the amount of change is stored as the second scale change amount. The product weight is stored in a memory, and one of the contents of the first scale change amount memory and the second scale change amount memory is compared with the product weight in the product weight memory corresponding to the product code read by the code scanner. , when the two match, a preset unit price is read out based on the product code read by the code scanner,
The unit price is registered as a single product as the sales amount of the product.

The present invention also provides the contents of the first scale change amount memory;
The contents of the second scale change amount memory and the product weight of the product weight memory corresponding to the product code read by the code scanner are compared, and when they all match, the product weight is calculated based on the product code read by the code scanner. The system reads a preset unit price and registers the unit price as the sales amount of the product.

A key Ks, a change key 6 for exchanging money, etc. are provided.

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 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 72nd scale 3 and stored in the second scale instruction value memory 83. At this time, the measured value is zero. In this state, the process of storing the measured value of the first scale 2 in the first scale instruction value memory 82 is repeated, and it is checked whether the contents of the first scale instruction value memory 82 are different from the contents of the work memory 88. That is, this will check that one of the items 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 8.
Store in 4. 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. Subsequently, the single product registration memory 81 is searched based on the product code stored in the scanning data memory 86, and the weight of the corresponding product is read from the weight area M4 and stored in the product weight temporary memory 90. 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. That is, this is to check whether the product that has been scanned is placed on the second scale 2. Second scale indication value memory 8
3 becomes 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 obtain the amount of change in the measured value, and the amount of change is calculated from the second scale instruction value memory 83. It is stored in the scale change amount memory 85. Then, the contents of the first scale change amount memory 84, the contents of the second scale change amount memory 85, and the contents of the product weight temporary memory are compared, and if the contents of all three do not match, scanning is performed. The product and the product placed on the second scale 3 are different, and it is determined that fraud has occurred, and an error process is performed. In this error handling, the cashier may be notified by a lamp or a buzzer. To cancel this error processing, use the keyboard 20
All you have to do is press 41 on the clear key. When the contents of the seventh scale change amount memory 84, the contents of the second scale change amount memory 85, and the contents of the product weight-poetry memory 90 all match, the product code stored in the scanning data memory 86 is By single item registration memory 81
Search for the unit price, number of sales points, and sales amount data from unit price area M3, sales point area ~15, and sales amount area N4s of the memory where the corresponding product code is stored, and add 1 to the sales point. Create a new sales number and add the unit price to the sales amount to create a new sales amount, store the updated sales number and sales amount in the sales number area M5 and sales amount area M6, respectively, and register one product. Process. 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 same contents match, it is determined that scanning of the product has not been completed, and the processing is repeated as described above. The process returns to the process of storing the contents of the first scale instruction value memory 82 in the work memory 88 in preparation 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. Thereafter, 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 way, single item registration processing can be performed by reading the product code attached to the product with the code scanner 4, and there is no need to operate any keys on the keyboard 20, so 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, when a customer performs an operation to read a product code, the customer first places all the products to be purchased on the first scale 2, then picks up the products one by one from the first scale and reads the product code with the code scanner 4. After that, the product is placed on the second scale 3. In this operation, each time the product is taken from the first scale 2, the amount of change in the weight value is detected, and each time the product is placed on the second scale 3, the amount of change in the weight value is detected, and the amount of change in the weight value is detected and set in advance. Compare the specific weight of the product whose code was scanned, the amount of change in the weight value on the first scale 2, and the amount of change in the weight value on the second scale 3, and find out that all three do not match. If this happens, it may be that some kind of fraud has occurred, such as the same item was not transferred correctly from the first scale 2 to the second scale 3, or multiple items of the same item were transferred at the same time in one scan. I try to judge and handle errors. Therefore, even if the cashier is away from his/her seat, he/she can easily know about fraud by the customer and prevent fraudulent registration.

In this way, the cashier does not have to constantly monitor the operations of the customers, and there is no need to worry about the work.

In addition, in the above-mentioned example, the comparison was made of the amount of change on the first scale 2, the amount of change on the second scale 3, and the product-specific weight, but it is not necessarily limited to this. without, the amount of change in the first scale 2,
Fraud detection may be performed by comparing one of the amounts of change on the second scale 3 with the weight specific to the product.

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 The present invention can also be applied to a so-called POS system in which the system is controlled by a terminal controller having a file memory, and in this case, the 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, it is possible to provide a product sales data processing system that can reduce the workload of the cashier and can reliably prevent fraud by customers without the need for supervision by the cashier. It is something.
