FIG. 1 is a flowchart for explaining the specific operation of one embodiment of the present invention, and FIGS. 5A and 5B are CR
6A and 6B are diagrams showing a basket buffer included in the RAM shown in FIG. 4. FIG.

Next, referring to FIGS. 1 to 6B, the invention Q-
The specific operation of the embodiment will be explained.

First, the operator operates the numeric keys and product keys on the full keyboard 21 to input the amount data and department code of the product purchased by the customer.
When it is determined that there is a key human input signal from the key input signal, the key input signal is pressed by the carriage return key 22. Correction key 26
．． Deposit/Cash key 25. ↑Key 23. Determine whether it is the ↓ key 24 or the numeric keypad. At this time, CR
A cursor is displayed at the data display position on the T-display 3.

When CPLJI determines that there is an input from the numeric keypad, it stores the input department, code, and amount data in the basket buffer 64 corresponding to the position where the cursor is displayed. For example, as shown in Figure 6A,
Department code 100. If the amount 1000 is entered,
After storing the data in the basket buffer 64, the data is displayed on the CRT display 3 as shown in FIG. 5A. Then, the CPU 1 moves the cursor display position to the right.

When the operator finishes registering the data regarding the first product, he operates the carriage return key 22 to enter data regarding the next product. When determining that the carriage return key 22 has been operated, the CPU 1 moves the cursor to the beginning of the next line. Then, the CPU 1 transfers data regarding the input product to the basket buffer 16.
4 and also displayed on the CRT display 3.

By repeating this operation, the basket buffer 6
4 stores data as shown in FIG. 6A, and the CRT
Data is displayed on the display 3 in the form S as shown in FIG. 5A.

If there is an error in the data input as described above, move the cursor to the right side of the incorrect data. That is, when the ↑ key 23 is operated, the CPUI moves the cursor directly above, and when the ↓ key 24 is operated, the CPUI moves the cursor directly below. When the correction key 26 is operated, the CPU 1 determines that the correction key 26 has been operated, and determines whether a flag has been set corresponding to the data regarding the product specified by the cursor.

If not set, a flag is set in the corresponding flag storage area.

Furthermore, the data regarding the product at the digit displayed by the cursor is deleted as shown in FIG. 5B.

At this time, if the operator accidentally corrects data related to a product that should not be corrected, he operates the correction key 26 again. When the CPU 1 determines that the correction key 26 has been operated, it determines whether a flag is set in the basket buffer corresponding to data regarding the corrected product. When it is determined that a flag has been set, the corresponding flag is cleared and the data regarding the product for which the flag was set is displayed again on the CRT display 3.

In this way, when correcting data related to an input product, move the cursor to the CR where the data is displayed.
By moving the item onto the T display 3 and operating the correction key 26, it is possible to erase the data related to the item with the M name, and to set a flag in the storage area of the corresponding basket buffer. If the operator erroneously corrects data regarding a product that should not be corrected, the original data can be displayed by simply operating the correction key 26 again.

The operator performs the above-mentioned correction process, and after registering all the data regarding the products purchased by the customer, operates the deposit/total key 25. When the CPU 1 determines that the deposit/total key 25 has been operated, it sets the pointer 62 to the first storage area 641 of the basket buffer 764. The CPU 1 searches the first storage area 641 of the basket buffer 764 specified by the pointer 62, and
Determine whether the flag is set. If the flag is not set, the contents of the first storage area 641 of the Basket Pup Allo 4 specified by the pointer are added to the total counter 63, and the amount data is added to the totalizer 65'. Then, the pointer 62 is incremented, and it is determined whether data is stored in the next storage area 642 designated by the incremented pointer 62. When it is determined that data is stored, the flag is searched.

As shown in FIG. 6B, a flag is set in the second storage area 642 of the basket buffer 764, so the data in the second storage area 642 is not added to the total counter 63 and totalizer 65. , increments the pointer 62.

This operation is repeated, and of the data stored in the basket buffer 64, only the data for which the flag is not set is added to the total counter 63, and the amount data is added to the totalizer 65. When all the data in the basket buffer 764 has been processed, detailed data of the products purchased by the customer is sent to the printer 4, and a receipt is issued. Then, the contents of the basket buffer 64 are cleared and the series of operations ends.

Effects of the Invention As described above, according to the present invention, inputted product price data is sequentially displayed on the display, and when the inputted product price data is corrected, a correction code is displayed on the display, and the correction code is displayed on the display. By setting a flag in the storage area corresponding to the amount data, it is possible to erase the amount data of the product on which the correction code is displayed. If the amount data of a product that should not be corrected is mistakenly corrected, simply by issuing a correction command again, the original amount data can be displayed and the flag cleared. Then, by giving a total calculation command, only the amount data for which no flag is set can be totaled and registered, and the operator only needs to give a command to display a correction code and a correction command. This eliminates the need to perform the same key sequence as in the past when registering, improving operability for the operator.
