An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, the POS terminal device 1 has a keyboard (KB) 2, a display device 3, a bar code input device 4, a CPU 5, a receipt printing device 6, and a memory 7.

The bar code input device 4 has a function of reading a bar code value from a product (not shown), a function of detecting whether or not an illegal digit is included in a part of the bar code, and a bar code of the bar code. It has a function of replacing an illegal digit with a preset mark (a code other than a numerical value) and notifying when the illegal digit is partially contained.

A control program 71 for controlling each device of the POS terminal device 1 and a PLU table 72 for searching for products are stored in the memory 7. P
The LU table 72 has a key 72a for each product and a product name 7
2b and price 72c are stored in association with each other, and the control program 71 is provided with a search function for searching the product name 72b and the price 72c from the key 72a in the PLU table 72.

FIG. 2 is a block diagram showing the configuration of the bar code input device 4 of FIG. In the figure, the bar code input device 4 includes a bar code reading section 41, a read data holding section 42, a read error detecting section 43, and a code replacing section 4.
4 and a read data output unit 45.

When the bar code reading unit 41 detects the reflected light (detection light) from the product and reads the bar code value from the product, the bar code reading unit 41 reads the read bar code value and the read error detection unit. 43 and output.

The read data holding unit 42 holds the bar code value from the bar code reading unit 41. The reading error detection unit 43 detects whether or not there is a reading error in the value of the barcode from the barcode reading unit 41.

That is, the reading error detecting section 43 detects whether or not there is a portion that the bar code reading section 41 cannot read, and detects the unreadable portion as a reading error. When the read error detection unit 43 detects a read error, the read error detection unit 43 notifies the code replacement unit 44 of the location (number of digits) of the read error.

The code replacing section 44 is a read error detecting section 4
When the location where the reading error occurs is notified from 3, the corresponding location of the bar code value held in the reading data holding unit 42 is replaced with a preset mark (a code other than a numerical value, for example, "N").

The read data output section 45 outputs the bar code value held in the read data holding section 42 as it is, if the read error detection section 43 does not detect a read error.

When the read error detection unit 43 detects a read error, the read data output unit 45 outputs the bar code value in which the position where the read error occurs is replaced by the mark by the code replacement unit 44.

FIG. 3 is a flowchart showing a PLU search operation according to an embodiment of the present invention. The operation of the embodiment of the present invention will be described with reference to FIGS.

When the key value of the product designated by the bar code read by the bar code input device 4 is input (step 11 in FIG. 3), the control program 71 marks the input key value (read error). It is determined whether there is any (step 12 in FIG. 3).

If there is no mark in the input key value, the control program 71 uses the PLU table 7 based on the key value.
Search for the product name 72b and the price 72c from 2 respectively, and enter PL
It is determined whether or not there is a corresponding key value in the U table 72 (step 13 in FIG. 3).

If there is a corresponding key value, the control program 71 displays the product name 72b and the price 72c retrieved from the PLU table 72 on the display device 3 to ask the operator for confirmation and to register the sales of the product. Perform (step 14 in FIG. 3) and end the process.

If there is no corresponding key value, the control program 71 notifies the operator of an error (error sound, etc.).
(Step 15 in FIG. 3). After that, the control program 7
1 performs sales registration based on the price of the product input by the operator from the keyboard 2 (step 16 in FIG. 3), and ends the process.

On the other hand, if the input key value has a mark, the control program 71 determines whether the number of marks is equal to or greater than a preset number, that is, whether or not the error occurrence location is equal to or greater than the preset number. 3 step 17).

If the number of marks is equal to or more than the set number, the control program 71 notifies the operator of an error (error sound, etc.).
(Step 15 in FIG. 3). After that, the control program 7
1 performs sales registration based on the price of the product input by the operator from the keyboard 2 (step 16 in FIG. 3), and ends the process.

If the number of marks is less than the set number, the control program 71 sequentially enters numerical values of 0 to 9 into the mark portion, and from the PLU table 72, the product name 72b and the price 7
2c are searched respectively, and the search results are temporarily held until this search is completed (steps 18 to 21 in FIG. 3).

The control program 71 displays a list of the temporarily held search results on the display device 3 (step 22 in FIG. 3) and prompts the operator to select the corresponding product. At this time, the control program 71 displays on the display device 3 all the product names 72b and prices 72c corresponding to those existing in the PLU table 72 among those in which the numerical value of 0 to 9 is entered in the mark portion.

The control program 71 determines whether the operator's input from the keyboard 2 is the selection key input to the list display of the display device 3 (step 23 in FIG. 2). When the control program 71 determines that the input from the keyboard 2 is the input of the selection key, the sales registration is performed based on the price of the product selected by the selection key and the like (step 2 in FIG. 2).
4), the process ends.

When the control program 71 determines that the input from the keyboard 2 is not the selection key input, it registers sales based on the price of the product input by the operator from the keyboard 2 (step 25 in FIG. 2). The process ends.

In the above processing, the case where the number of illegal digits is one is described. However, when the number of illegal digits is two or more, the upper digit or the lower digit is fixed and the digits can be sequentially changed from 0 to 9. You can do it. However, the more illegal digits there are, the more P
Since it takes a long time to search the LU table 72, if it takes too long to search the PLU table 72, the number of marks to be set may be reduced.

In the above example, the bar code input device 4 detects whether or not there is a reading error in the bar code value.
However, it is also possible to pass all the values read by the barcode input device 4 side (including the unreadable portion) to the CPU 5 and detect the reading error on the CPU 5 side.

As described above, when a reading error is detected in the key value designated by the bar code input, the product name 7 corresponding to the key value other than the detected reading error portion is displayed.
2b and the price 72c are all searched from the PLU table 72, and the search results are displayed on the display device 3 as a list.
The operator does not need to repeatedly input the bar code until the bar code is successfully read.

Therefore, even if a barcode reading error occurs, the data of the product can be retrieved from the PLU table 72, and the sales of the product can be registered.

[0037]

As described above, according to the present invention, when a reading error is detected in the key value designated by the bar code input, the product name corresponding to the key value other than the detected reading error location. By searching for the price and the price and displaying the list of the search results, the data of the product can be searched from the PLU table even if a barcode reading error occurs, and the sales of the product can be registered. The effect is that you can do it.
