[Embodiment] FIG. 2 shows an embodiment of the purchase amount calculation cart device of the present invention.

50 is a cart that allows the total purchase amount to be calculated, and the 5th item is a control unit for calculating the purchase amount, and this control unit 5l includes a bar indicating the product type written on the product. Barcode reading device 52 that reads the code
, a keyboard 53 for adding consumption tax, etc., a display 54 for displaying the purchase amount, etc., and an antenna 55 for communicating with a host computer (hereinafter simply referred to as host) 100.

On the other hand, on the host l00 side, 101 is a register consisting of a keyboard 102, a CRT display 103, and a barcode reading device 104.

105 is a main control unit for communicating with a plurality of carts 50, and 106 is an antenna.

The control block diagram of the above system is shown in Figure 3.
The same parts as in FIG. 2 are given the same reference numerals.

In the cart 50, 56 is a barcode reading device 1.
The barcode information of the product read in 52 is sent to the host 10.
0 and also receives product price information transmitted from the host 100 in response to the transmitted barcode information. 57 is an arithmetic unit that calculates the purchase amount by adding the product prices transmitted from the host l00.

Further, in the host 100, a memory 107 stores the price of the product inputted from the keyboard 102 in advance for each barcode indicating the product type.

10B is a transmitting/receiving device for communicating with the cart 50.

Next, the operation of the system having the above configuration will be explained according to the flowcharts shown in FIGS. 4 and 5.

If the mode is set to input data such as product prices by key operations on the keyboard 102, the initial setting flow shown in FIG. 4 is executed.

First, when a barcode is input using the barcode reading device 103, the process advances from step S1 to step S2, and the read barcode is taken into the main control unit +05. Next, in step S3, the price of the product and the amount of consumption tax are input using the keyboard 102. In addition, if necessary,
Enter a comment such as that it is today's special price item. The entered data such as the product price can be confirmed on the CRT display 103. In step S4, the input data is stored in the memory 10 along with barcode information.
7 is stored.

Data input in steps Sl-S4 is performed for all products, and when all input is completed, by operating a predetermined key, the process proceeds to the purchase amount calculation flow shown in FIG. 5, which will be described below. Note that when the price of a product is changed, the same input as described above is performed for that product, and the previous data stored in the memory 107 is erased and updated with the new data input later.

In FIG. 5, when the customer reads the barcode of the product he or she wants to purchase using the barcode reading device 52, the process proceeds from step Stt to step S13, and the information on the read barcode is transferred from the cart 50 to the host 100. Sent. On the other hand, on the host l00 side,
When the barcode information is received from the cart 50, the process advances from step S51 to step S52, and data such as the price of the product corresponding to the transmitted barcode is read from the memory l07, and is transmitted to the host 50 in step S53. . At this time, since the data is transmitted together with the barcode information, the cart 50 side
It is possible to determine whether the data was sent to 0.

Now, when the data is received by the corresponding cart 50, the process proceeds from step S14 to step S15, and the amount stored in the calculating section 57 is added to the current price to calculate the total amount. In step S16, the calculated total amount is displayed on the display 54 along with the price and the comment. Thereafter, the process returns to step Sll, and by performing the same operations as described above for the next item to be purchased, the prices are added one after another and the total amount is displayed.

Once the total amount is determined in this way, next
If consumption tax addition processing is selected using the key device No. 3, the process proceeds from step Sll to step S17, where an amount added by 3% to the total amount is calculated, and step S18
The total amount including tax will be displayed.

Also, if the calculated total amount exceeds the budget amount,
Select the subtraction mode by operating a predetermined key. Thereby, the process advances from step Sll to step S19. Here, when the barcode of the product for which the purchase is to be canceled is read, the price data of the product is read out in the same manner as described above in steps 920 to S21, and in step S22, the price data of the product is read out from the calculated total price. The price of the product is subtracted, and the price of the product and the subtracted total amount are displayed in step S23. If you further wish to cancel the purchase of the product, please follow steps S19 to S2.
All you have to do is repeat the subtraction mode in step 3.

Note that the barcode attached to each product indicates the product type and does not include price information as the price may fluctuate. Therefore, it is necessary to affix a price sticker etc. to each product, which takes time and effort. However, with the above device, the price of the product is immediately read from the barcode, so there is no need for price stickers, which saves time and effort. .

Note that the original function of the register in the host 100 is the same as in the past, and the barcode reading device 10
