Then, the merchandise registration section 53 transmits the cancellation data including the customer identification code and the merchandise identification code of the canceled merchandise to the host device 1 (n80). The product registration unit 53 displays the total price of the products registered after registration or cancellation of the registration and the total weight of the products stored in the product storage unit 51 on the display unit 67 (n8).
1). Therefore, the display unit 67 always displays the total price and total weight of the products stored in the product storage unit 51. As described above, in this embodiment, whether the product is stored in the product storage unit 51 or taken out is detected by whether the cancel key 66a is operated. That is, when the information is read from the bar code without operating the cancel key 66a, it is determined that the product is stored in the product storage unit 51, and when the information is read from the bar code after the cancel key 66a is operated, the product storage unit 51 is read. It is determined that the product has been taken out.

The host device 1 is also provided with a transaction data file for storing transaction data for each shopping cart 3. FIG. 15 is a diagram showing the structure of a transaction data file.

In the transaction data file, a customer identification code for identifying a customer and a transaction record in which the price and weight of the product are stored in association with the product identification code for identifying the product are registered. The host device 1 is n92
Create a transaction data file when you register as a customer. When receiving registration data or cancellation data from the shopping cart 3 (n93, n94), the host device 1 registers or deletes a transaction record in the transaction data file of the corresponding shopping cart 3 (n95, n96).

That is, when the customer takes out the merchandise from the display shelf and registers the merchandise, the registration data is transmitted to the host device 1. Therefore, the host device 1 can monitor the movement of the product in real time, and can easily replenish the product whose quantity is insufficient. Further, it is possible to know the route in which the customer moves in the store, and to easily plan the layout of the sales floor so that the customer does not move in the store unnecessarily, thereby improving the customer service. The host device can also manage transactions for each customer based on the customer identification code.

When the customer repeatedly registers and cancels the above-mentioned products and completes the registration of all the products to be purchased (when all the products to be purchased are registered and stored in the product storage unit 41), the customer pushes the shopping cart 3 Go to the cash register.

At the cash register, the operator deposits the customer card from the customer and causes the transaction processing device 3 to read the bar code of the customer card. Then, the operator removes the commodity storage unit 41 from the shopping cart 3 and places it on the scale 79 provided in the transaction processing apparatus 3.

When the transaction data is read from the customer card (n101), the transaction processing device 2 sends a shopping end signal including the customer identification code to the host device 1 (n102).

When the host device 1 receives the shopping end signal (n97), it transmits the transaction data file of the corresponding customer to the transaction processing device 2 (n98).

When the transaction processing device 2 receives the transaction data file from the host device 1 (n103), it calculates the total weight of the registered merchandise (n104), and stores the merchandise measured by the calculated total weight and a scale. The weights of the products stored in the section 41 are compared (n105), and if they are substantially the same, transaction processing such as printing a slip with the pudding and the section 75 is performed (n106).

Therefore, the transaction processing device 2 can register the merchandise by receiving the transaction data file from the host device 1. Therefore, the time required for the work of registering the commodity in the transaction processing apparatus 2 can be shortened, and the cashier congestion can be eliminated.

As described above, by displaying the total price of the products stored in the product storage unit 41 on the display unit 47, the total price of the products stored in the product storage unit 41 can be displayed during the shopping. You can inform the customer. Therefore, the customer can shop without feeling anxiety as to whether or not he has insufficient cash.

By displaying the total weight of the products stored in the product storage unit 41 on the display unit 47, the total weight of the products stored in the product storage unit 41 can be notified to the customer who is in the middle of shopping. it can. Therefore, the customer can shop without worrying about whether or not he or she can bring back the product to be purchased from the store.

By the way, when the weights do not substantially match in the comparison of n105, the transaction processing device 3 stops the transaction (n107). When the transaction is stopped, the operator registers the products in the transaction processing device 3 one by one and performs the transaction process with the customer. As described above, the reason why the weights do not substantially match in the comparison of n105 is that the customer does not register the product and the product storage unit 41
This is the case when there is a fraud such as storing a product in. Therefore, in such a case, the merchandise can be prevented from being illegally taken out of the store by registering the merchandise in the transaction processing device 3 one by one.

In this embodiment, the customer has the customer card 6
Although it is assumed that 0 is owned in advance, a cart number may be given to the cart and a shopping start signal may be output when the product is first registered. In this case, the transaction processing apparatus 2 sends a shopping end signal to the host apparatus 1 when the operator inputs the cart number.

The transaction data may be output by the shopping cart 3.

Furthermore, the transaction processing system can be constructed by combining the first embodiment and the second embodiment.
For example, in the first embodiment, the shopping cart 3 may be provided with a scale to display the weight of the products stored in the product storage unit 11.

As described above, according to the present invention, when the merchandise registration device stores merchandise in the merchandise storage portion, the stored merchandise is registered, and the prices of all the registered merchandise are summed up. Display the total price you made. Therefore, if the merchandise registration device is a merchandise cart (a cart that stores the merchandise that the customer purchases while moving in the store and takes it to the cash register), the customer is currently planning to purchase the merchandise even if the customer is in the middle of shopping. You can know the total price of (commodities stored in the product storage section), and customers can shop without worrying whether the transaction amount charged at the cash register is insufficient with the cash they have. You can

Further, it is possible to easily register a product by attaching a medium storing product data such as a product identification code to the product and receiving the product data such as the product identification code output from this medium.

Further, the merchandise can be registered by reading the merchandise data from the printed bar code having the merchandise data such as the merchandise identification code as information.

When it is detected that the product is taken out of the product storage unit, the registration of the taken-out product is canceled.

When the product is stored in the product storage unit, the product moves from the top to the bottom in the product storage unit, and when the product is taken out from the product storage unit, the product moves from the bottom to the top in the product storage unit. Therefore, it is possible to easily determine whether the product is stored in the product storage unit or taken out from the product storage unit in the order in which the two sensors provided on the upper and lower portions of the product storage unit detect the movement.

Further, since the merchandise registration device measures and displays the weight of the merchandise stored in the merchandise storage section, the customer is wondering whether the merchandise stored in the merchandise storage section can be brought back from the store. You can shop without thinking.

Further, in the transaction processing system of the present invention,
The transaction processing device can detect the data registered in the product registration device and process the transaction using the detected data without registering the products one by one at the cash register. Therefore, it is possible to shorten the time required to register the product, eliminate the congestion of the cash register without expanding the cash register space, and improve the customer service at the same time.
