Description

[Detailed description of the invention]

The present invention relates to a method for setting a bar code in a printer, and more particularly to a method for setting a bar code code system and displaying the position of a check digit in the code system. Conventionally, the most suitable code system for barcodes is selected based on the target product to be marked using a code comparison table, and a barcode based on the selected code system is printed using a printer. This is based on the convention that the barcode code system places a flag code at the beginning, followed by an item code, a price check digit, a price, and a module check digit at the end. As shown in the table, there are various code systems, such as those with different number of digits for the item code, those without a price check digit, and those without a price.
Not only is it difficult for operators to accurately memorize all of these code systems, but it is also easy to make input errors, so code comparison tables have had to be used. Therefore, inputting barcode data was inefficient. However, if the position of the flag code and each check digit or the presence or absence of the check digit is known, it becomes easy to set the number of each code for other items and prices, eliminating erroneous input of bar code data and improving the input operation.

[Table] Conventionally, the value of the check digit was calculated manually according to a predetermined arithmetic formula, and the value was placed at the position of the check digit determined by the code system. Therefore, a lot of time has to be spent on numerical calculations, which reduces work efficiency in inputting barcode data. Moreover, when the calculation was done manually, there was a problem that it inevitably caused calculation errors. Accordingly, an object of the present invention is to provide the first aspect of item 1, wherein, by inputting a flag, the flag and the check digit of the code system having the flag are displayed together on the display section. According to the invention, the invention eliminates erroneous input of barcode data, improves the work efficiency of the input operation, and automatically calculates a check digit based on the number of barcode data. Therefore, it is possible to further improve the efficiency of input operations and to eliminate errors in calculation of check digits. The barcode code setting method according to the first invention described in paragraph 1 is such that various code systems to be used are stored in advance in a storage unit of a signal control mechanism constituting a printer, and flags of these are set in the printer. By inputting with a numeric keypad or dial switch, etc., the code system with the flag is recalled from the storage section, and the flag is displayed on the display section of the printer controlled by the signal control mechanism.
The check digit of the code system having the flag is displayed at a predetermined digit position, and then the code is set.The display format of the check digit is, for example, "C" in the displayed digit column.
, or a display light may be provided either above or below the digit column and lit or blinking to indicate the check digit digit column. Hereinafter, one embodiment of the first invention described in item 1 will be described with reference to the drawings. Figure 1 is a perspective view of the printer, and Figure 2 is a block diagram of the printer, where A is an input section consisting of a numeric keypad 1 and a dial switch 2, B is a signal control mechanism, C is a display section, and D is a recording mechanism. It is. The input section A includes a numeric keypad 1 for inputting numerical values on the operation panel 3 on the front of the system, a dial switch 2 for specifying a flag 7, a clear key 4 for erasing incorrectly entered numerical values, a program/label issue switch 5,
Other various keys are provided, and their output sides are connected to the signal control mechanism B. The signal control mechanism B includes a storage unit that stores the bar code code system and other data, and a control unit that operates the display unit C connected to the output side, the recording mechanism D, etc. in a predetermined form according to the input signal. and an arithmetic unit that receives input signals and processes them as information, stores various code systems of bar codes in the arithmetic storage unit, and inputs the flag 7 by operating the numeric keypad 1 or dial switch 2. , the check digit E of the code system with the flag 7 is displayed as "C" in the designated digit column of the display section C.
is displayed. The display section C consists of a display window 6 consisting of a 13-digit digit column, and by input operation of the numeric keypad 1 or dial switch 2, a number or C is displayed in each digit column on the display tube. The recording mechanism D sets the program/label issue changeover switch 5 to the program side, inputs barcode data using the numeric keypad 1 or the dial switch 2 and the numeric keypad 1, and then switches the changeover switch 5 to the label issue side. By doing so, the barcode data displayed on the display window 6 is printed on the label. Therefore, flag 7 is "02"
To explain how to set the JAN13NONPLU type code system using Figure 3, first set the program/label issue switch 5 to the program side, then press numeric keypad 1 to 0.2 in sequence or set dial switch 2 to the 02 mark. . Then, by that input signal, the flag 7 of "02" is stored in the memory section of the signal control mechanism B.
The JAN13NONPLU type code system is read out, and the check digit 8 and module check digit 8' of the price are displayed at the 8th position in the display window 6 along with the flag 7 which is displayed as 0.2 in the first and second digit columns. "C" is displayed in the digit field and the 13th digit field, respectively. This shows that the 5 digits from the 3rd digit field to the 7th digit field are the item code, and the 4 digits from the 9th digit field to the 12th digit field are the price code. Enter the item code and price code in sequence, and then switch the program/label issue switch 5 to the label issue side.
A JAN13NONPLU type barcode is printed on the label. Also, when setting the JAN8PLU type code system where flag 7 is "0", press 0 on numeric keypad 1 or set dial switch 2 to the 0 mark as shown in Figure 4.
Just as when setting the JAN13NONPLU type code system, flag 7 "0" is placed in the first digit field.
is displayed, and the module check digit "C" is displayed in the 8th digit field, allowing the operator to understand that the 6 digits from the 2nd digit field to the 7th digit field are the item code. . Therefore, by inputting the flag, the position of the check digit of the code system that can be set and the presence or absence of the check digit of the price are displayed, so the operator can easily know the position of the item code and price code, and the number of the set code can be displayed. This can be done quickly without looking at the code comparison table, improving the efficiency of barcode label issuing work and eliminating barcode data input errors. Next, the second invention described in item 2 will be explained below. This second invention inputs a flag, then sequentially sets each barcode data according to the code system that has the flag, and automatically calculates a check digit based on the set number to set the barcode code. This method is the same as the first invention in that when a flag is input, the code system having the flag is displayed at the positions of the flag and the check digit. Automatic calculation of check digits by inputting barcode data will be explained in detail with reference to FIGS. 1 to 4 and FIGS. 5 and 6, which were used to explain the first invention. The value of check digit E is calculated using a predetermined arithmetic expression using the values of flag 7, item code 9, and price code 10 as variables. Therefore, the calculation formula is stored in the signal control mechanism B in advance, and each code is entered in each digit column of the code system displayed on the display unit 6 by inputting the flag 7, and the entry is completed. Then, the value of the check digit E is calculated using these input signals and the stored arithmetic expression, and the value is displayed on the display section 6.
Each part of the signal control mechanism B is configured so that the check digit E is displayed in the digit column of the check digit E which is already displayed as "C". Therefore, as shown in FIG. 3, the flag 7 of "02" is displayed in the first and second digit columns of the display section 6, and the position of the check digit E is displayed as "C" in the 8th and 13th digit columns, respectively. ” is also displayed.
Set the JAN13NONPLU type code system,
Next, enter a 5-digit item code 9 such as "11142" and a 4-digit price code 10 such as "0123" sequentially from the third digit column using the numeric keypad 1, and enter the last digit of the price code 10, that is, the display section 6. After placing "3" in the 12th digit field,
The value of each check digit E is automatically calculated based on the input signals of "02" of flag 7, "11142" of item code 9, and "0123" of price code 10, and is entered in the column of check digit 8 of the price. ``1'' is displayed in the column of module check digit 8', and ``0'' is displayed in the column of module check digit 8' (FIG. 5). Further, as shown in FIG. 4, a flag 7 of "0" is displayed in the first position of the display section 5, and the position of the module check digit 8' is "C" in the eighth digit column.
Set the code system of the JAN8PLU type displayed with
When the digit code 9, for example ``123456'' is entered using the numeric keypad 1, ``5'' is displayed in the module check digit 8' column (FIG. 6). Note that the position of the check digit, its value, and barcode data are not limited to those that are displayed on the display section, but may also be recorded and displayed using a recording mechanism. Therefore, the value of the check digit is automatically calculated simply by inputting the barcode data, which saves the time and effort of numerical calculation, and eliminates the issuance of defective labels due to incorrect calculation of the check digit. Since the present invention is a barcode code setting method as described above, according to the first invention described in paragraph 1, it is possible to improve the efficiency of barcode label issuing work and eliminate input errors in barcode data. According to the second invention, the work efficiency can be further improved, and there will be no issue of defective labels due to miscalculation of check digits, and even part-time workers can easily set barcode codes. This has a great economic effect on store operations. Thus, the intended purpose can be achieved.
