When the sealing is completed, the weighing section conveyor 18 is driven to move the shopping bag 25 onto the transport conveyor 16, and then the weighing section vertical motor 23 is driven to raise the weighing and bagging mechanism 15 to the original initial position. . Then, the processing routine returns to the opening control of the door 4a of the input port 4. In the above, the registration unit end switch 8
Is input, the settlement section checks whether the settlement of the previous customer has been completed. If not, wait until it is finished. If the payment for the previous customer has been completed, the total amount is displayed on the registration unit display 5. Subsequently, it is checked whether or not the door 4a of the slot 4 is open. If the door 4a is open, the door 4a is closed and the content of the counter 442 is incremented by one. Also, if it is already closed, this count-up process is passed. Subsequently, the weighing unit vertical motor 23 is driven to lower the weighing and bagging mechanism 15, and the upper end of the shopping bag is sealed by the seal unit 29. When the seal is completed, the data of the item name / unit price storage area 447, the total amount storage area 448, and the counter 442 are set in the output buffer 444, and then output to the settlement unit via the transmission control circuit 46.

Reader 74 is connected. The CPU 61 controls each section based on the program data stored in the ROM 63. The control is performed according to the flowchart shown in FIG. First, the total amount of the data input from the registration unit via the transmission control circuit 68 is displayed in the display buffer 6.
The information is displayed on the settlement unit 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 is stored in the total amount storage area 647, and the count content N is stored in the counter 644. At the same time, "Please insert a card."
Message is also displayed. In this state, a card input to the card 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 to check whether the credit card is a correct card. If there is an error in the card, an error is made. If the card is normal, a message "Please input your password" is displayed following the payment display 11, and the keyboard 1 is displayed.
It waits for the password input from 0. In this state, when a password is input from the keyboard 10, it is checked whether the password is correct in relation to the card, and an error is made if the password is incorrect. If the password is correct, for example, a message such as "Please confirm the total amount. Press the payment end switch." In this state, the operation waits for the input of the settlement end switch 12. When the settlement end switch 12 is input, the data of the item name / unit price storage area 646 and the total amount storage area 647 are first registered in the registration memory 648, and are sequentially output to the print buffer 643 and received by the printer 73. It prints out on paper and issues a receipt from the receipt issuing port 13. Then, a message "Please take a card." Is displayed on the payment display unit 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. 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 place the shopping bag in the shopping bag outlet 1.
4 and then control to unlock the outlet 14 is performed. Subsequently, a message "Please pick up the product." Is displayed on the settlement unit display 11. Thereafter, a signal from the bag outlet sensor 32 is checked to check whether a shopping bag is taken out from the outlet 14, and every time a shopping bag is taken out, the content N of the counter 644 is decremented by one. When the content N becomes zero, it is determined that all the shopping bags for the customer have been removed. Then, a message "Please close the shopping bag outlet" is displayed on the balance display 11 and a predetermined time is waited. After that, the total amount displayed on the display 11 is erased, and a message “Thank you very much.” Is displayed. In this embodiment constructed as described above, first, the customer places the shopping basket containing the goods on the table 2 and operates the start switch 7. Thereby, the charging port 4 is opened. Therefore, a shopping bag is set inside the slot 4. In this state, the merchandise is taken out of the shopping cart and passed over the marker 3 and the bar code attached to the merchandise is passed toward the bar code reading surface of the laser scanner 6. After the barcode is read, the product is put into the shopping bag through the slot 4. Since the weight in the shopping bag changes when a product is put into the shopping bag, the change in the weight is the weight set in advance for the product corresponding to the bar code read by the laser scanner 6. Check if it matches. That is, 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 is read. It is checked whether the goods put in the shopping bag match. By this comparison processing, incorrect merchandise sales registration due to fraud or unclear barcode can be prevented. When the data match is determined, the marker 3 emits green light to prompt the customer to read the barcode of the next product because the data input is correct. Further, when it is determined that the data does not match, the marker 3 emits red light and the customer is erroneously inputting data. Therefore, the user is prompted to take out the current product from the shopping bag and read the barcode again. When the shopping bag becomes full during the bar code reading process of the product, the door 4a is closed once, the shopping bag is sealed, and the product is sent to the transport conveyor 16. Thereafter, the door 4a of the slot 4 is opened again. As a result, the customer performs an operation of setting a new shopping bag and putting the shopping basket product into the shopping bag after passing through the marker 3 and the laser scanner 6. When the shopping basket has been completely loaded into the shopping bag, the registration section end switch 8 is turned on.
Perform the above operation. As a result, the total amount is displayed on the registration unit display 5 and the slot 4 is closed. Also,
Inside, the upper end of the shopping bag is automatically sealed while the weighing and bagging mechanism 15 is lowered. Then, when the weighing and bagging mechanism 15 moves down to the lowest position, the weighing section conveyor 18 operates and transfers the shopping bags on the conveyor to the transport conveyor 16. Therefore, when one customer's shopping product is divided into a plurality of shopping bags and placed, the plurality of shopping bags are placed on the conveyor 16. In addition, the registration unit sends the item name, unit price, total amount, and count number N indicating the number of shopping bags of each product 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 checkout section, inserts a credit card into the card insertion slot 9, and inputs a personal identification number from the keyboard 10. As a result, inquiries such as a card number and a password are made, and if the inquiry is correct, a payment settlement process is performed.
Issued from No. 3. Further, the 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. At this time, the number of shopping bags to be taken out is counted by the counter 644. When the customer takes out the corresponding number of shopping bags, the counter 644 becomes zero, the take-out opening 14 is closed and the lock is activated. As described above, in the registration unit, the customer causes the laser scanner 6 to read the bar code of the product purchased by the customer, and inserts the read product into the shopping bag set in the insertion slot 4. You can input product sales data and pack products into shopping bags. When a product is put into the shopping bag through the slot 4, the weight change is checked and compared with the weight of the corresponding product read out in advance by a bar code to check whether the products match or not. Therefore, for example, if there is a fraud such as putting a product different from the product corresponding to the bar code read by the laser scanner 6 into the shopping bag from the slot 4 or the bar code is dirty and erroneously read as another data. In such a case, it can be determined as abnormal. Further, the marker is illuminated in green when the product put in the shopping bag and the product from which the bar code has been read are matched, and in the case of mismatch, the marker is illuminated in red to notify the customer. The customer can determine whether to read the bar code of the next product or to read the bar code again for the product put in the shopping bag by looking at the emission color of the marker 3. In the settlement section, the customer inserts a credit card into the card insertion slot 9 and inputs a personal identification number, thereby completing payment settlement for the goods purchased by the customer and issuing a receipt. Further, the customer can receive a shopping bag containing the product purchased by the customer from the shopping bag outlet 14. As described above, the customer can perform the registration work using the laser scanner 6 and the settlement work of the registered merchandise in one apparatus main body without the intervention of the cashier. In addition, by comparing the weight data, it is possible to surely prevent an unauthorized input operation by the customer. As described in detail above, according to the present invention, both the registration work and the settlement work can be performed only by the customer without the intervention of the cashier, and the unauthorized input operation by the customer can be reliably prevented. A product sales data processing device can be provided.
