[0004]

The correction processing method of a POS device of the present invention is a correction processing of a POS device for writing sales data in a sales information file by inputting a product code or scanning a barcode and printing sales details on a receipt. In this method, when sales data is written to the sales information file, the POS number, receipt number, and storage address of the sales information file are written to the transaction search file, and the POS number and receipt number with check digit added are used as receipts. Data writing means for printing, number data checking means for checking the number data by the check digit added when the number data of the receipt printed by the data writing means is input, and this number data checking means According to the number data checked by Data reading means for searching the transaction search file to read the storage address of the sales information file and reading the sales data at this storage address of the sales information file; and cancellation data for the sales data read by the data reading means. As data canceling means for writing a sales details file on a receipt and printing a cancellation statement on a receipt, a statement correcting means for deleting or adding a specified statement by the sales data read by the data reading means, and a statement correcting method The sales data corrected by the means is written in the sales information file as correction data, and the correction data updating means for printing the corrected sales statement on the receipt is included.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. In the embodiment of FIG. 1, the sales data input from the input device 1 is written in the sales information file 3, the POS number, the receipt number, and the storage address of the sales information file are written in the transaction search file 4, and the POS number and the receipt at that time are written. When the number data is input from the data writing unit 2 that prints out the number data in which a check digit is added to the number on the receipt through the output device 5 and the input device 1, the check digit of the number data is changed to the number. The number check unit 6 for checking the data and the number data P
Disassemble the OS number and the receipt number, read the transaction search file 4 to obtain the storage address, and read the sales data from the sales information file 3, and the sales data read from the data reading unit 7. A data cancellation unit 8 that writes data as sales data to the sales information file 3 and prints the cancellation details on the receipt via the output device 5, and the specification details input from the input device 1 for the sales data read from the sales information file 3. And a correction data updating unit 10 for writing the corrected sales data as correction data in the sales information file 3 and printing the corrected sales details on a receipt via the output device 5. It consists of

FIG. 2 is a flow chart showing the procedure of sales processing in the embodiment of FIG. The process of FIG. 1 will be described with reference to FIG. When the operator inputs the sales data using the input device 1 (keyboard and optical reader) (step 11), the data writing unit 2 writes the sales detail information in the sales information file 3 (step 12). Data writing unit 2
Is the PO to be used as an index key when correcting the transaction.
Write the S number, receipt number, and storage address of the sales information file in the transaction index file 4 (step 1
3). Further, a check digit is calculated by a certain calculation method based on the POS number and the receipt number (step 1
4) Add the calculated check digit to the POS number and receipt number to make number data (step 1
5), the number data is output to the receipt via the output device 5 together with the sales detail information (step 16).

FIG. 3 is a flowchart showing the procedure of the correction process of the embodiment shown in FIG. When the operator wants to correct the sales transaction after the sales processing is finished, first, after the correction processing work is declared from the input device 1, the sales receipt to be corrected printed by the output device 5 in the sales processing procedure. Number data of the input device 1 is input (step 2).
1). The number data check unit 6 checks whether the input value is correct from the manually input contents with a check digit (step 22), and if correct, decomposes the number data into a POS number and a receipt number (step 23), and then the POS number and the receipt. Transaction search file 4 with number as key
Is acquired to obtain the storage address of the sales information file 3 (step 24). If the number data input in step 22 is incorrect, it is regarded as an incorrect input, an error message is output, and the process ends (step 32). When the result of the input check is correct and the storage address is acquired in step 24, the data reading unit 7 reads the sales information file 6 using the storage address as a key (step 2
5), Acquire sales data to be corrected. Next, the data cancellation unit 8 writes the sales data as cancellation data in the sales information file 3 (steps 26 and 27), and then outputs it to the receipt via the output device 5 (step 2).
8). Here, the operator inputs deletion and registration of necessary details from the input device 1 (step 29). Next, when the operator declares the end of the cancellation processing operation, the detail correction unit 9 corrects the sales data, and the correction data updating unit 10 writes the corrected sales data in the sales information file 3 (step 30), and after the correction. The sales details are output to the receipt via the output device (step 31).

[0009]

As described above, according to the present invention, the operator prints the number data on the receipt in advance, and the number data and the address of the sales data written in the sales information file have a corresponding file so that the operator can When correcting the receipt, you only need to input the number data and details and delete the registration, and you can obtain the receipt of the revised sales information file and the corrected details without having to re-enter all sales details. There is an effect that the operation can be simplified and the operation error can be prevented.
