In the apparatus according to the embodiment of the present invention thus configured, the customer first places the shopping basket containing the products 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 basket 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. At this time, when a product is placed in the shopping bag and its weight changes, it is determined whether or not the amount of change in the weight matches the preset weight of the product corresponding to the barcode read by the laser scanner 6. By checking the data from, the product with the barcode read and the product actually put in the shopping bag are matched to prevent fraud. This kind of work is performed for all the products in the shopping basket. At this time, when the shopping bag becomes full in the middle, 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. In this way, the customer again sets the shopping bag, passes the products in the shopping basket through the marker 3 and the laser scanner 6, and puts them in the shopping bag. In this way, when all the products in the shopping basket have been put into the shopping bag, the registration section end switch 8 is operated next. As a result, the total amount of money is displayed on the registration unit display 5 and the slot 4 is closed. In addition, the upper end of the shopping bag is automatically sealed while the weighing and bagging mechanism 15 descends inside. 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 one customer's shopping product is divided into a plurality of shopping bags and put, 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. In this way, the inquiry about the card number, the personal identification number, and the like is performed, and if the inquiry is correct, the receipt issuance port 13 issues a receipt on which the input data is printed. Further, the data is cumulatively registered in the registration memory 648. 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 number of shopping bags corresponding to the customer is taken out, the counter 644 becomes zero and the takeout opening 14 is locked as soon as it is closed.

In this way, in the registration section, the customer sells the product by having the customer scan the product purchased by himself / herself with the laser scanner 6 and read the barcode attached to the product and put it in the shopping bag set in the insertion slot 4. Data entry and product packing in shopping bags can be performed without employees. Then, in the settlement section, the customer inserts a credit card and inputs a personal identification number to complete payment for the product purchased by the customer, and a receipt is issued to the customer.
Further, the customer can receive the shopping bag containing the product purchased by himself / herself from the shopping bag outlet 14. Therefore, it is possible to eliminate the need for employees in the settlement department. Moreover,
In the registration section, when the product is put into the shopping bag set from the input port 4, the weight change is checked and compared with the weight of the corresponding product read in advance by the bar code. If there is an illegality such that a product different from the product corresponding to the barcode read in 6 is put into the shopping bag through the slot 4, it can be correctly determined.

[Effects of the Invention] As described in detail above, according to the present invention, an employee such as a cashier is not required, only the customer can perform the registration processing of the product sales data and the settlement processing of the registration data, and the customer can not perform fraud.
