The present invention relates to an electronic fare scale with a barcode printer. Technical Background of the Invention and Problems Thereto Conventionally, this type of barcode printer has been equipped with a deep switch compatible with the barcode format, but there are various barcode formats. In order to accommodate various formats, it is necessary to provide a large number of deep switches. Furthermore, if a new format appears, it cannot be handled and a new format must be developed each time. As a result, there are many cases where the user's requests cannot be met. Purpose of the Invention The present invention was made in view of the above points, and an object of the present invention is to obtain an electronic fare scale with a barcode printer that can easily handle all barcode formats requested by users. . SUMMARY OF THE INVENTION The present invention is configured to be able to handle all barcode formats requested by the user by eliminating the dip switch method and setting the barcode format by key input. Embodiments of the Invention First, the electronic fare scale 1 includes a weighing section 3 having a mounting plate 2.
and a display section 5 attached to the upper end of the support column 4. This display section 5 has the same display on both sides,
Regarding the display arrangement on one side, as shown in FIG. 2, it has a weight display section 6, a unit price display section 7, a price display section 8, etc. Also, on the left end is the zero point (ZERO),
LED 9 is provided to display each of tare (TARE), fixation (FIX), error (ERROR), and print (PRINT). Next, a keyboard section 11 is provided on the front side of the main body case 10 of the weighing section 3, and a display section 1 for displaying the PLU code or date is provided on the left side of the keyboard section 11.
2, and a receipt issuing port 13 is provided on the right side of the keyboard section 11. next,
A key switch operation section 14 is provided on the back side of the main body case 10, as shown in FIG. The key switch operation section 14 has a scale zero setting switch 15, an analog double check circuit test switch 16, an operation section changeover switch 17, a recording mode changeover switch 18, and a key switch 19.
Here, the key switch 19 is PR2, PR1,
EIN, AUS, X, Z, RAM CLEAR, TEST
It is possible to switch to 8 READ modes. "PR2"
Use the remote keyboard described below to enter the PLU product name, unit price, group number, PLU code, weighing/non-weighing classification, date, time, store name, store code, and machine.
This is the mode for setting No., barcode flags, etc. Next, the one shown in FIG. 4 is a remote keyboard 20, which has a plug 21 connected to a connection port (not shown) of the main body case 10, and has a large number of keys 22 as shown in FIG. has been done. This remote keyboard 20 is connected to the key switch 19.
This is used to set the unit price, product name, date, time, barcode flag, etc. of the PLU when it is in "PR2" mode. Next, the outline of electrical connections of each part will be explained based on FIG. First, the load cell 23 is connected to the ADC circuit 24, and this ADC circuit 24 is connected to the CPU 2.
5. This CPU25 has I/O
Block 26 is connected, and this I/O block 2
6 is connected to a thermal printer 27 serving as a printing section and a display block 28. The remote keyboard 20 and the keyboard 7 section 11 are connected to this display block 28. Although not particularly shown, a deep switch for setting various specifications of the electronic fare scale 1 is provided in the main body case 10 of the weighing section 3 as an internal switch. These deep switches cannot be changed after being shipped from the manufacturer. Next, the main flow will be explained based on FIGS. 7 and 8. First, after the start, memory clearing, ROM check, I/O initial setting, and deep switch reading are performed, and then the registration mode changeover switch 18 is read. here,
A check is made to see if it is OFF. If it is OFF, it means early registration (AUS1) or firm registration (AUS2), and if it is not OFF, it means single item tightening registration (EIN). Here, descriptions of the contents of quick registration, advance registration, single item tightening registration, etc. are omitted because they are not important to the present invention. Now, if you have a single item tightening registration (EIN),
Go to MAIN 0, check the parity of the deep switch, and then check the segment of the display. Here, the display of 0 to 9 and the non-touching are repeated. Then, when the exposure data becomes stable, the zero range is checked, a power outage is detected, and the process reaches MAIN in Figure 8. In addition, when the registration mode changeover switch 18 is OFF (AUS) in FIG.
When the seconds have passed, the display goes out, reads the date switch, reads the registration mode changeover switch 18 again, and if it is OFF here, the light-up data is read out, the light-up data is processed, and the display returns to the position where the light goes out. Here, the registration mode changeover switch 18 is set to
If it is not OFF, go to MAIN 1, check the parity of the deep switch, and check the segment of the display. The segment at this time is a repetition of 8 and off. Then, when the exposure data becomes stable, a zero range check and power outage detection are performed, leading to the MAIN shown in Figure 8. In FIG. 8, a mode check is performed and a front switch check is performed. Here, the term "front switch" refers to the operation section changeover switch 17 and the registration mode changeover switch 18, and the details of this front switch check will be omitted. When this check is completed, a check is made to see if the registration mode changeover switch 18 is OFF.
If so, the display returns to OFF in FIG. 7, and if it is not OFF, a check is made to see if the key is present. Here, if a key is present, a check is made to see if it is a front key. This "front key"
is a key on the keyboard section 11, and if it is a front key, front key processing is performed.
Its contents are omitted. After that processing, a check is made to see if net calculation is necessary, and if necessary, a cross is calculated, and the net is determined by subtracting the tare amount from this gross. Also, a check is made as to whether or not price calculation is necessary, and if necessary, the price is determined by multiplying the net by the unit price, the price is rounded by means such as rounding, and the price is displayed using a lamp.
Double check the display. If it is not a front key, it is a key on the remote keyboard 20, so remote key processing is performed, a lamp is displayed, and a display double check is performed. Furthermore, if the key is not pressed when the above-mentioned check is performed to see if the key is present or not, the scanner reads the exposure data, processes the exposure data, performs auto-zero processing, and switches the registration mode changeover switch 18.
Checks whether or not is OFF. If it is OFF, it returns to the OFF position in Figure 7. If it is not OFF, it returns to the OFF position in Figure 7. If it is not OFF, it reads date and time data from a quartz timer (not shown) provided inside the main body case 10. Lead. Then, it is checked whether net calculation is necessary or not, and if necessary, gross calculation is performed and auto-clear is performed, net is obtained by subtracting the tare weight from gross, and auto-clear conditions are checked. Next, it is checked whether price calculation is necessary or not, and if necessary, the net is multiplied by the unit price to round up the price. Then, display the lamp, double-check the display, and return to MAIN. However, the barcode format is usually
It is 13 digits, but there are abbreviated 8-digit and 6-digit E versions. In any case, there are various barcode formats as illustrated in Tables 1 and 2. In the table, JAN is Japan, EAN is Europe, UPC is America, TEC is individual-specific, INDUSTRY
indicates industrial use. Also, in the format, 04 etc. represent a flag, C represents a code, P represents a price, C/D represents an overall check digit, and PC/D represents a price check digit. There are various barcode formats as described above, but no matter what format it is, the 8th
Necessary format settings are made by key operations in the remote KEY process in the main flow shown in the figure. Now, as an example, the operation procedure for setting the UPC barcode format shown in No. 06 is shown in the PAM RAM map that acts as a storage means as shown in Fig. 9.
This will be explained based on Table 3 while referring to the flowcharts of FIGS. 10 to 26.

[Table] First, as shown in step 1, the setting is started by pressing the "B" key on the remote keyboard 20, and when the "B" key, which acts as a means to start this setting, is pressed, the barcode setting counter BCDSCT is set to 1. do. At this time, the display state is as follows. Input counter that shows how many characters are entered next
Set NCUNT to 0, clear all FORMATs 1 to 6 and BARCODs 1 to 13 shown in the RAM map of FIG. 9, and return. This is the KEY1 process based on the flowchart in Figure 10.
This is shown in Figure 1. Next, as in step 2, input the number of digits of the barcode format using the setting key. Now, assume that it is the 13-digit E version, and enter "1" and "3" using the keys. As a result, the flow becomes KEY2 in Figure 12, and when the content of the barcode setting counter BCDSCT is 1 to 5, KEY20 to KEY24 is set.
processing is executed. Currently, the content of the barcode setting counter BCDSCT is 1, so KEY20
processing is performed. This KEY20 process is performed as shown in Figure 13.
13) is displayed on the price display section 8. After inputting the number of digits, pressing the "ENTER" key shown in step 3 causes the processing of KEY4, and when the content of the barcode setting counter BCDSCT is 1 to 5, the processing of KEY40 to KEY44 is executed. Now the barcode setting counter
Since the content of BCDSCT is 1, the process moves to KEY 40 as shown in FIG. This KEY
40 is the number displayed as shown in Figure 20, that is, the number of digits in the barcode format.
After storing it in FORMAT6 in the RAM map, take the display state in Table 3 and write the counter NCUNT.
Set the contents to 0 and set the barcode setting counter.
Add 1 to BCDSCT and return. here,
If the number of digits is 0, the content of FORMAT6 is 0, so the process returns to the initial display shown in the display, the content of the barcode setting counter BCDSCT is set to 0, and the process returns. After pressing the "ENTER" key, move to step 4, flag input, using the setting key. Flag input is 1 digit or 2
This is a digit number, and is entered by key-inputting, for example, "0" or "2". This allows the KEY
2 processing, the second KEY21 is flagged, and as shown in Figure 14, after the input number (for example 02) is displayed, the input number counter is displayed.
Adds 1 to the contents of NCUNT and returns.
Then, by pressing the "ENTER" key according to step 5, the process moves to the second KEY41 during KEY4 processing. That is, as shown in FIG. 21, processing is performed depending on whether the content of the input number counter NCUNT is 1 or 2. First, if it is 1, it means that the number of flag digits is 1, and the displayed number is
After storing in BARCOD1, set the contents of FORMAT1 to 1, set the input number counter NCUNT to 0,
The following barcode address BARADR
Specify BARCOD2. After passing through the display state, 1 is added to the barcode setting counter BCDSCT and the process returns. On the other hand, if the content of NCUNT is not 1, it means that the number of flag digits is 2, and the displayed number is BARCOD1,
Store each in BARCOD2, set the contents of FORMAT1 to 2, set NCUNT to 0, specify barcode address BARADR to BARCOD3, display, and then return. Flag input is performed in this way, but if there is no flag, if you press the "ENTER" key directly without entering a value,
Since NCUNT=0, FORMAT1 is set to 0. Following the flag input described above, the code is input in step 6 using the setting key. This is to input the number of digits of the product code to be printed on the barcode, and the number of digits from the left side of the printing position is entered as a number. For example, "1""2""3""4"
Key in "5". By inputting this value, the first
As shown in FIG. 5, processing of KEY22 is performed.
In other words, the input numbers are displayed, the input numbers are sequentially stored at the address indicated by the barcode address BARADR, the count number of NCUNT is incremented by 1, and the barcode address BARADR is also set to the next address.
Specify BARADR. Then, when you press the "ENTER" key in step 7, it is the third time and the second
The processing of KEY 42 shown in FIG. 2 is performed. That is,
The number of code digits in NCUNT (for example, 5) is stored in FORMAT2, NCUNT becomes 0, the price display section 8 turns off, the barcode setting counter BCDSCT is incremented by 1, and the process returns. Next, use the setting key to input whether the price check digit PC/D is present or not according to step 8. If there is, set "1", otherwise set "0". Table 3 shows the case where there is PC/D and "1" is set. As a result, as shown in Figure 16,
The KEY 23 is processed and the input number "0" or "1" is displayed. and,
When the "ENTER" key in step 9 is pressed for the fourth time, the process of KEY 43 shown in FIG. 23 is performed. In other words, if the display is not 1, it means that there is no PC/D, and FORMAT3 is set to 0, but if the display is 1
If so, there is a PC/D, and the FORMAT
3 is set to 1, barcode address
1 is stored in the address BARCOD indicated by BARADR,
BARADR specifies the next address. Then, the display on the price display section 8 becomes a state where the light is dimmed,
Add 1 to the barcode setting counter BCDSCT and return. Then, according to step 10, input whether to print the price or weight using the "P" or "W" key. As a result, KEY3 as shown in Figure 18
will be processed, and the barcode setting counter will be
Provided that BCDSCT is 5, if the "P" key is pressed, it is a price.
FORMAT5 is set to 0. On the other hand, if you use the "W" key, FORMAT5 is 1 due to weight.
is set to Then, it will be in the display state,
P for "P" key, 0 for "W" key
is displayed. Thereafter, the PW flag is set to 1 and the process returns. In this way, after setting the price or weight,
Follow step 11 and enter the numerical value using the numeric keys (for example, "4", "3", "2" as shown in Table 3).
"1"). With this key operation, the
Processing of KEY24 is performed. That is, the entered number is displayed under the PW flag = 1,
The contents of NCUNT are incremented by 1. And the steps
When you press the "ENTER" key on number 13, it is the fifth time,
The processing of KEY 44 shown in FIG. 24 is performed.
In other words, if the PW flag is not 1, it will jump, but if it is 1, the displayed number will be BARADR.
Store sequentially from the address indicated by and save it to FORMAT4.
Stores the contents (number of digits) of NCUNT. here,
If there is no price check digit PC/D, leave it as is, if there is, NCUNT = 4 or
After checking whether NCUNT=5, FORMAT1
The contents of ~4 are added to give s. And this s
Check whether the barcode is equal to the contents of FORMAT 6, and if they are not equal, the number of digits of the barcode input at the beginning does not match the number of digits input by setting, and an error occurs. If they are equal, it is OK, all flags and counters are cleared, the display returns to the initial display, 1 is added to the barcode setting counter BCDSCT, and the setting is completed. By the way, if you input the module check digit using the setting key, that is, the "C" key in step 12 after inputting the value of price or weight, the process of KEY25 shown in Fig. 25 will occur, and the contents of the barcode setting counter BCDSCT will change to On the condition that
The contents of NCUNT are incremented by 1. The barcode format is set by operating the keys 22 on the remote keyboard 20 as described above. Therefore, in the receipt issuing mode shown in FIG. 26, following the total receipt issuing,
If the contents of FORMAT6 (number of digits) is not 0,
A barcode is printed on the receipt based on the contents of BARCOD1-13 and the number of digits in FORMAT6. On the other hand, if all are set to 0, the contents of FORMAT6 will also be 0, and no barcode will be printed on the receipt. Therefore, even when barcode printing is not necessary, it can be easily handled. Table 4 is similar to Table 3, but shows an example of the format setting procedure when the bar code is an 8-digit shortened version.
