In particular, FIG. 5 shows the input processing operation of the purchase quantity, and FIG. 6 shows the registration processing operation. 7 shows the report creation processing operation, and FIG. 8 shows the inventory clearing processing operation.

Next, the operation of one embodiment of the present invention will be described with reference to FIGS. 1 to 8.

First, the purchase quantity input processing operation shown in FIG. 5 will be explained. The operator operates the mode changeover switch 31 to switch to the program mode. Then, key operations as shown in FIG. 3(a) are performed. CP of POS terminal device 1
In response to a predetermined key operation, U2 searches the PLU file 70 based on the input PLU code, and determines whether the area 76 is reserved in the PLU record containing the PLU code. . The PLU concerned
If the area 76 is not secured in the record, inventory calculation will not be performed for the item in question, so an error message will be displayed on the display 4 and the process will wait until the next key operation is performed.

On the other hand, if area 76 is secured in the PLU record, new inventory quantity data is obtained by adding the inputted purchase quantity data to the inventory quantity data stored in area 76, and the addition result is is stored in area 76. Subsequently, the CPU 2 waits until a key operation is performed for the next product.

The operator performs the key operations shown in FIG. 3(a) for all purchased products. In response, the CPU 2 repeatedly performs the above-described inventory update processing operation for each product, and ends the operation in response to the operation of the NS/# key 36.

Next, the registration processing operation shown in FIG. 6 will be explained. When performing registration processing, the operator switches the mode changeover switch 31 to the registration mode.

Then, for the product purchased by the customer, the PLU of that product
Enter the code using the numeric keypad 33, and then press the PLU key 37. In response to the input of the PLU code, the CPU 2 executes the PL based on the input PLU code.
Search the U file 70 and search for P that includes the PLU code.
It is determined whether or not area 76 is secured in the LO record. If area space δ is secured, the inventory quantity data stored in area 76 is decremented by 1, and area 7
The unit price data stored in area 75 and the disc libta data stored in area 75 are read out and displayed on display 4, and printed on the receipt by printer 5.Then, the cumulative sales data in area 75 is increased by +1. Then, the cumulative sales amount data in area 72 is updated.

On the other hand, if the area 76 is not secured, the above-described stock quantity update process is skipped.

Next, the report creation processing operation shown in FIG. 7 will be explained. When creating a report, the operator operates the mode changeover switch 31 to switch to inspection mode or payment mode. The CPU 2 reads a PLU record for each product from the PLU file 70, and prints the PLU code, product name data, cumulative sales quantity data, and cumulative sales amount data, as shown in FIG. Next, CPU2
determines whether or not area 76 is reserved, and if area 76 is reserved, the characters “ZAIKOSUU” read from area 75 and the inventory quantity data read from area 76 are stored in a predetermined buffer in RAM 7. Then, the contents of the buffer are printed on a report by the printer 5. On the other hand, if area 76 is not secured,
Skip the printing process for inventory quantities.

Next, the inventory clearing processing operation shown in FIG. 8 will be explained. When clearing the inventory quantity, the operator operates the mode changeover switch 31 to switch to the program mode. Then, key operations as shown in FIG. 3(b) are performed. If there is key power, the CPU 2 determines whether or not a PLO code has been input before the PLU key 37 is operated, and if a PLU code has been input, performs clearing processing for each product. Therefore, the PLU file 70 is searched based on the input PLU code, and it is determined whether or not there is a matching PLU code. If a matching PLU code does not exist, error processing is performed, but if a matching PLU code exists, the area 76 of the PLU record containing the PLU code is
Set the inventory quantity data stored in . The CPU 2 repeats the above-mentioned operation every time the PLU code is input, and when the NS/# key 36 is operated, ends the inventory clearing process.

On the other hand, if no PLU code is input before the PLU key 37 is operated, the inventory quantity of all PLU records is set to 0, and in response to the NS/# key 36 being operated,
Finish the inventory clearing process.

[Effects of the Invention] As described above, according to the present invention, each time purchase quantity data and a product code are input in the setting mode, the count value of the counting means corresponding to the product code is calculated by the input product. Update based on input quantity data, and in registration mode, each time a product code is input, the sales quantity is subtracted from the count value of the counting method corresponding to the product code, and in report creation mode, the sales quantity is Since a numerical report is created, when you want to know the inventory quantity, you can immediately issue the report. Store staff can check the inventory quantity by simply looking at the report instead of counting the inventory quantity as in the past. can be understood. Furthermore, since there is no need to install a host computer for inventory management, inventory management can be easily performed with less capital.
