First, of the data input from the registration unit via the transmission control circuit 68, the total amount of money is displayed in the display buffer 6.
It is displayed on the settlement section display 11 via 42. The item name and unit price of the data input from the registration unit are stored in the item name / unit price storage area 646,
The total amount of money is stored in the total amount of money storage area 647, and the count content N is stored in the counter 644. At the same time, "Please insert a card."
Is also displayed.

In this state, a card input to the card insertion slot 9 is awaited. When a credit card is inserted into the card insertion slot 9, the data of the card is read by the card reader 74 and it is checked whether or not the credit card is correct. If there is something wrong with the card, it is judged as an error, and if it is normal, the message "Please enter your PIN" is displayed following the settlement indicator 11 and the keyboard 1
Wait for the PIN code input from 0.

When a personal identification number is input from the keyboard 10 in this state, it is checked whether the personal identification number is correct in relation to the card, and if it is incorrect, an error is generated. If the personal identification number is correct, a message such as "Please check the total amount of money. Please press the settlement end switch." Is displayed on the settlement unit display 11.

In this state, the operation waits for the input of the settlement end switch 12. When the settlement end switch 12 is input, first, the data in the item name / unit price storage area 646 and the total amount storage area 647 are cumulatively registered in the registration memory 648, and then sequentially output to the print buffer 643 and received by the printer 73. The sheet is printed out and the receipt is issued from the receipt issuing port 13. Then, the message "Please take the card." Is displayed on the settlement section display 11.

Subsequently, the input from the bag outlet sensor 32 is checked to determine whether the shopping bag has reached the shopping bag outlet 14. Then, if it has already arrived, the bag outlet opening / closing lock solenoid 22 is controlled to be released to unlock the outlet 14. If it has not arrived, the conveyor 16 is driven to remove the shopping bag from the shopping bag outlet 1.
After moving to 4, the unlocking control of the outlet 14 is performed.

Then, the message "Please take merchandise." Is displayed on the settlement section display 11. Thereafter, the signal from the bag outlet sensor 32 is checked to check whether the shopping bag is taken out from the outlet 14, and the content N of the counter 644 is decremented by 1 each time the shopping bag is taken out. When the content N becomes zero, it is judged that all the shopping bags for the customer have been taken out. Then, a message "Please close the shopping bag outlet" is displayed on the settlement unit display 11 and a predetermined time is waited. After that, the total amount of money displayed on the display 11 is erased, and the message "Thank you for every time." Is displayed.

In the present embodiment thus constructed, the customer first places the shopping basket containing the goods on the table 2 and operates the start switch 7. As a result, the charging port 4 is opened. Then, the shopping bag is set inside the inlet 4.

In this state, the product is taken out of the shopping cart and passed over the marker 3, and the bar code attached to the product is passed toward the bar code reading surface of the laser scanner 6. Then, the product for which the reading of the barcode is completed is put into the shopping bag through the input port 4.

Since the weight inside the shopping bag changes as the product is put into the shopping bag, the weight change is preset for the product corresponding to the bar code read by the laser scanner 6. Check if it matches. In other words, the weight data of the corresponding product read from the weight data storage area 449 and the weight data obtained by subtracting the data of the A register 445 from the data of the B register 446 are checked, and the bar code is read and the actual product. Check to see if the products in your shopping bag match.

By this comparison processing, it is possible to prevent erroneous processing of inputting merchandise sales data due to fraud or unclear bar codes. When it is determined that the data match, the marker 3 emits green light to prompt the customer to shift to reading the bar code of the next product because the data input is correct. Further, when it is determined that the data do not match, the marker 3 emits red light, and the customer is erroneously inputting the data. Therefore, the customer is prompted to take out the current product from the shopping bag and read the barcode again.

If the shopping bag becomes full during the bar code reading process of the product, the door 4a is once closed and the shopping bag is sealed and sent to the conveyor 16. After that, the door 4a of the charging port 4 is opened again. Thereby, the customer sets a new shopping bag, passes the marker 3 and the laser scanner 6 at the shopping basket, and puts the product in the shopping bag.

When all the products in the shopping basket have been put into the shopping bag in this way, the registration section end switch 8 is then operated.
Perform the operation of. As a result, the total amount of money is displayed on the registration unit display 5 and the insertion slot 4 is closed. Also,
Inside, the weighing and bagging mechanism 15 descends and the upper end of the shopping bag is automatically sealed. When the weighing and bagging mechanism 15 descends to the lowest position, the scale section conveyor 18 operates to transfer the shopping bag on the conveyor to the conveyor 16.

Therefore, when the shopping product of one customer is divided into a plurality of shopping bags and put therein, the plurality of shopping bags are placed on the conveyor 16. In addition, data of the item name, unit price and total price of each product, and the count number N indicating the number of shopping bags are sent from the registration unit to the settlement unit.

In the settlement section, the total amount sent from the registration section is displayed on the settlement section display 11. Then, the customer goes to the settlement section, inserts the credit card into the card insertion slot 9, and inputs the personal identification number from the keyboard 10. This will inquire about the card number, PIN, etc., and if it is correct, the payment settlement process will be performed, and the receipt printed with the entered product sales data and the total amount will be the receipt issuing port 1
Issued from 3. Further, cumulative registration in the registration memory 648 based on the data is performed. Further, the opening / closing lock mechanism 22 is released, and the shopping bag outlet 14 can be opened.

Thus, the customer finally opens the shopping bag outlet 14 and takes out the shopping bag. The number of shopping bags taken out at this time is counted by the counter 644, and when the customer takes out the corresponding number of shopping bags, the counter 644 becomes zero and the take-out port 14 is closed and locked.

Thus, in the registration section, the customer causes the laser scanner 6 to read the bar code of the purchased product and puts the read product into the shopping bag set in the insertion slot 4. You can enter product sales data and pack products in shopping bags.

Then, when a product is put into the shopping bag through the inlet 4, the change in weight is checked and compared with the weight of the corresponding product read in advance by the bar code to check whether the products match or not. Therefore, for example, if there is a fraud such as inserting a product different from the product corresponding to the barcode read by the laser scanner 6 into the shopping bag from the slot 4, or the barcode is dirty and mistakenly read as different data. In such a case, it can be judged as abnormal.

Since the marker emits green light when the product put in the shopping bag and the product for which the barcode is read match, and when they do not match, the marker emits red light to notify the customer. The customer can judge whether to read the barcode of the next product or to read the barcode of the product put in the shopping bag again by looking at the light emission color of the marker 3.

In the settlement section, the customer inserts the credit card into the card insertion slot 9 and inputs the personal identification number to complete the payment settlement for the product purchased by the customer and issue a receipt. Further, the customer can receive the shopping bag containing the product purchased by him / her from the shopping bag outlet 14.

As described above, the customer can input the product sales data using the laser scanner 6 without interposing a cashier. Moreover, by comparing the weight data, it is possible to prevent erroneous input processing due to illegal input operation or the like.

In addition, the scale section conveyor 18 which is a product placing section
Put the shopping bag on the top, put the barcode-reading product into the shopping bag, and then detect the change in the weight data from the scale 17 and put the barcode-reading product into the shopping bag. Since it is determined whether the product matches or does not match, the product matching and mismatch determination and the product bagging operation can be performed simultaneously with the bar code reading operation simultaneously, and the workability can be improved.

[0065]

As described above in detail, according to the present invention, only the customer can input the product sales data without interposing a cashier, and it is possible to prevent an erroneous input process due to an illegitimate input operation. When an input operation etc. occurs, it can be notified, and the work of determining whether products match or mismatch and placing products on the product placement section can be performed simultaneously with the input operation of product sales data at the same time. It is possible to provide a product sales data processing device that can improve the
