Next, the operation of the present label printer 1 will be explained along the flowcharts shown in FIGS. 8 to 11. Now, when the power switch 7 is turned on,
The CPU 51 sets the initial conditions as shown in the main routine of FIG.
Clear 3,54, clear RAM67,
Feed the ribbon 32 by a certain amount. At this time, if the ribbon feed direction identification flag SPF is "1", the ribbon feed motor 35 is rotated in the forward direction for a certain period of time, and if the ribbon feed direction identification flag SPF is "0", the ribbon feed motor 35 is rotated in the reverse direction for a certain period of time. By doing so, the slack of the ribbon 32 is absorbed. continue,
After giving the timer set signal TS to the I/O unit 53 and setting the key scan timer 61,
Repeat the following loop. In the process of repeatedly processing the subsequent loop, when the key scan timer 61 has elapsed for a set time (approximately 10 ms), the key scan timer 61 provides an interrupt signal TW to the CPU 51. Then,
After executing the timer interrupt process shown in FIG. 9, the CPU 51 returns to the main routine shown in FIG. 8 and continues the process. In timer interrupt processing, check whether a key is pressed or not, and check the command reception flag.
It is sequentially determined whether the CMF is "1" and whether the buzzer 21 is on, and if both are not, the key scan timer 61 is directly reset. Therefore, since the key scan timer 61 is reset at the end of the timer interrupt process,
Timer interrupt processing is executed every time the set time of the key scan timer 61 elapses.

Therefore, a specific usage method will be explained. The method of use includes three operations selected by the mode changeover switch 8, that is, the first scale _H1 or the second scale H1.
The data sent from scale H ₂ is labeled 2.
Automatic issuance work that automatically prints and issues to 9, print key 11 or print = key 1
2. Manual issuing task of printing and issuing data from the first scale _H1 or second scale _H2 corresponding to the pressed key on a label 29 each time 2 is pressed, and print key 11 or print key 12.
In addition to the fixed amount issuance business in which the data entered from the keyboard on the first and second scales H ₁ and H ₂ corresponding to the key pressed each time is printed as a price on the label 29, the above-mentioned There is a mode in which the data compiled in each business is printed on a label and issued.

In the case of automatic issuance work, the mode changeover switch 8 is switched to the automatic position. Then, the 8th
In the subsequent loop of the main routine in the figure,
As a result of determining whether there is code data in the key buffer memory KBM and whether the mode changeover switch 8 is in the automatic mode, the automatic mode code is sent to the first and second scales _H1 and _H2 , and the first scale It is sequentially determined whether there is a print command from _H1 or whether there is a print command from second scale _H2 . Here, depending on the result of the judgment that there is no print command from either the first or second scale H ₁ or H ₂ , the process returns to after the process of or. Therefore, in this case, in addition to repeatedly processing the loop (or), the key scan timer 61 is in a state in which timer interrupt processing is executed every time the set time elapses.

Here, the first scale H ₁ or the second scale
In H ₂ , after setting the unit price per unit weight using the keyboard, when the object to be weighed is placed on weighing pan b, the weight of the object is measured, and
The price is calculated from the unit price data and weight data,
After these data are displayed on the display, a print command is sent to the label printer 1.

Now, when a print command is sent from the first scale _H1 , after determining it, the command reception flag CMF is set to "1", the data identification flag DAF is set to "1", and the Data from scale H ₁ (unit price, weight, and price) is taken into data storage memory.
Store in DAM. Also, when a print command is sent from the second scale _H2 , after determining it, the command reception flag CMF is set to "1", the data identification flag CAF is reset to "0", and the The data from scale H ₂ is taken in and stored in the data storage memory DAM. At this time, the command reception flag is set based on the print command from the first scale _H1 or the second scale _H2 .
When the CMF is set, when the timer interrupt processing is entered after the set time of the key scan timer 61 has elapsed, as a result of the judgment, the buzzer 21 is turned on (the buzzer on/off flag BUF is set to "1"),
〓〓 After resetting the command reception flag CMF to "0", 〓〓 processing is performed. As a result, when the timer interrupt processing is entered again, the command reception flag CMF is reset to "0" and the buzzer 21 is on (determined by the buzzer on/off flag BUF being "1"), so the judgment of Result, 〓〓
After turning off the buzzer 21 (resetting the buzzer on/off flag (BUF) to "0"), the following process is performed. Therefore, when a print command is given from the first scale _H1 or the second scale _H2 , the setting time of the key scan timer 61 (approximately 10 ms)
Since the buzzer 21 is ringing during this time, the following will be explained later.
Even if the label issuing switch 9 is turned off, that is, the label is not issued, it is possible to notify that the process is actually being performed. In this way, when the data from either scale H ₁ or H ₂ is stored in the data storage memory DAM, the data in the data storage memory DAM, that is, the print data, is then transferred to the print buffer memory.
PBM is set, and it is determined whether the label issue switch 9 is on. At this time, if the label issuing switch 9 is not on, the label 29 is not issued and the process directly proceeds to 〓〓, but if the label issuing switch 9 is on, then the 〓〓 label issuing process is performed.

In the label issuing process, as shown in Fig. 10, first, the ribbon feeding direction identification flag SPF is checked;
If it is "1", the ribbon feed motor 35 is rotated in the forward direction, and if it is "0", the ribbon feed motor 35 is rotated in the reverse direction, and then the label feed motor 26 is rotated.
Label feeding is started by driving the print buffer memory PBM, and the data in the print buffer memory PBM is given to the I/O unit 53, which is printed on the label 29 by the print head 33 controlled by the driver circuit 66. When printing is completed, the label feeding is stopped by stopping the drive of the label feeding motor 26, and then it is determined whether or not there is a ribbon end detection signal RD from the ribbon end detector 50. At this time, if there is no ribbon end detection signal RD, that is, if the ribbon 32 is not at the end, the process directly proceeds to 〓〓. In addition, if there is a ribbon end detection signal RD, that is, if the ribbon 32 has reached the end, then the ribbon feed direction identification flag is
Invert the SPF and turn on the buzzer 21 (set the buzzer on/off flag BUF to "1"),
= The ribbon feed motor 35 is rotated in reverse or forward direction depending on the state of the ribbon feed direction identification flag SPF.
A timer (not shown) is set, and after the set time of the timer has elapsed, the ribbon feed motor 35 is stopped and the buzzer 21 is turned off. Therefore, after the label is issued,
If the ribbon 32 has reached the end, the feeding direction of the ribbon 32 is reversed and the ribbon 32 is preliminary fed for a certain period of time.
The ribbon 32 is now in a state where it can be smoothly fed during the next printing. During this time, the buzzer 21 is turned on to prompt the operator to wait for a key operation.

After this, check the data identification flag DAF, and if it is “1”, the first total memory
Add the price data of the print data to TO ₁ M, add "1" to the first point memory CO ₁ M, and if "0", add the price data of the print data to the second total memory TO ₂ M. , and the second point memory (CO ₂ M), it is determined whether or not there is a label detection signal LD from the label detector 30. Here, if there is a label detection signal LD, that is, if the label 29 is normal, the label abnormality detection lamp 17 is turned off, and if there is no label detection signal LD, the label abnormality detection lamp 1 is turned off.
After performing the process of lighting 7, return to key-in.

Therefore, in the case of automatic issuing work, each time a print command is received from the first scale H ₁ or the second scale H ₂ , the label issuing switch 9 is turned on, and the scales H ₁ and H In addition to automatically printing the data from ₂ on label 29,
The price data is stored in the first or second total memory.
TO ₁ M, TO ₂ M, transfer the score data to the 1st or 2nd
Addition processing will be performed to the point memory CO ₁ M and CO ₂ M respectively. If the label issuing switch 9 is off, no labels will be issued, but only price data and point data will be tallied.

In the case of manual issuance work, the mode changeover switch 8 is switched to the manual position. Then, the 8th
In the subsequent loop of the main routine in the figure,
After determining the manual mode code as the first,
It is sent to the second scales H ₁ and H ₂ and returns after performing or processing depending on the next judgment. Therefore, in this case, (or)
The key scan timer 61 executes timer interrupt processing every time the set time elapses.

Here, after measuring the weight with either the first or second scale H ₁ or H ₂ , for example, the second scale H ₂ ,
To print the data, press the print key 12. Then, as a result of the judgment in the timer interrupt process in FIG. . After this, the processing in the main routine of FIG. 8 continues, but when the key scan timer 61 returns to the timer interrupt processing again after the set time elapses,
After the judgment, since the buzzer 21 is on in the judgment, then 〓〓 After turning off the buzzer 21,
〓〓 Process. Therefore, when a key is pressed,
A key confirmation sound will be emitted in synchronization with the timer interrupt processing at a fixed period. On the other hand, when continuing the processing in the main routine of FIG. 8, it is determined that there is code data in the key buffer memory KBM, so the process proceeds to the next key processing.

In key processing, as shown in FIG.
1, print key 12, and total key 13. In this case, it is the print key 12, so next, after resetting the data identification flag DAF to "0",
〓〓 Determine whether the total key flag TOF is “1”. In this case, the total key flag TOF is "0", that is, the total key 13 is not pressed, so
Next, it is determined whether the mode changeover switch 8 is in the automatic mode. Since the mode changeover switch 8 is in manual mode, after sending _the print request code to the second scale _H2 ,
It is determined whether there is a print command or not. Here, in the second scale _H2 , if it receives a print request code from the label printer 1 before weight measurement, it will not issue a print command, but if after weight measurement, it will issue a print command in response to the print request code. send. Then, when it is detected that a print command has been sent, the command reception flag CMF is set to "1", and the data from the second scale _H2 is taken in and stored in the data storage memory DAM. ,〓〓〓 Determine whether the mode changeover switch 8 is in the flat rate mode. Since the mode changeover switch 8 is in manual mode, after setting the following data in the data storage memory DAM, that is, unit price, weight, and price data as print data to the print buffer memory PBM, the label printing switch 9 is on. Here, if the label issuing switch 9 is not on, the process directly proceeds to 〓〓, but if the label issuing switch 9 is on, after performing the 〓 label issuing process (Fig. 10), 〓〓 The price data is added to the total memory TO ₂ M, and "1" is added to the second score memory CO ₂ M.

On the other hand, to print the data from the first scale _H1 , press the print key 11. Then, in the timer interrupt process, the code data of the print key 11 is stored in the key buffer memory KBM.
is stored in As a result, in the key processing shown in FIG. 11, after detecting the print key 11 in the determination of 〓, 〓〓 data identification flag DAF is set to "1", and 〓〓 determines whether total key flag TOF is "1" or not. 〓〓It is determined in order whether the mode changeover switch 8 is in the automatic mode. Here, the total key flag
Since TOF is “0” and mode changeover switch 8 is in manual mode, next
After sending it to the first scale _H1 , it is determined whether there is a print command from the first scale _H1 . As a result, if there is a print command from the first scale _H1 , then the command reception flag CMF is set to “1”.
After taking the data from the first scale _H1 and storing it in the data storage memory DAM,
The decision will be made.

Therefore, in the case of manual issuance work, the first scale
After placing an object to be weighed on H ₁ or the second scale H ₂ , pressing the print key 11 or 12 corresponding to that scale will cause the scale to release the item, provided that the label issuing switch 9 is on. Along with printing the data on the label,
The price data is stored in the first or second total memory.
TO ₁ M, TO ₂ M, transfer the score data to the 1st or 2nd
Addition processing will be performed to the point memory CO ₁ M and CO ₂ M respectively. If the label issue switch 9 is off, no labels will be issued, but only the price data and score data will be tallied.

In the case of fixed amount issuing business, the mode changeover switch 8 is switched to the fixed amount position. Then, the 8th
In the subsequent loop of the main routine in the figure,
After determining, enter the flat rate mode code first.
It is sent to the second scales H ₁ and H ₂ and returns after processing or according to the next judgment. Therefore, in this case, (or)
The key scan timer 61 executes timer interrupt processing every time the set time elapses.

Here, after setting the count data using the digital switch 10a corresponding to the two-digit year of the date setting switch 10, the print key 11 or the print key 12 is pressed. Then, in the timer interrupt process, the code data of the pressed key is stored in the key buffer memory KBM. As a result, in the key processing shown in FIG. 11, processing based on print key 11 or print key 12 is performed in the same way as in the manual issuing operation. However, in the case of this fixed-rate issuing business, since the mode changeover switch 8 is set to the fixed-rate mode in the judgment of 〓〓, 〓〓print data, in this case, the unit price data is set in the print buffer memory PBM, and 〓setting data storage memory is set. After setting the DGM count data to the print buffer memory PBM and setting the label name of the flat rate label, for example, "Flat Rate" to the print buffer memory PBM, the process proceeds to the determination of 〓〓.

Therefore, in the case of flat rate issuance work, manual operation is required, except that the unit price data from the scale is printed as the price, and the count data set by the date setting switch 10 and the label name of the flat rate label are printed. It is the same as the publishing business.

The above is the processing in the automatic issuance business, manual issuance business, and fixed amount issuance business. In these businesses, price and point data are stored in the first and second total memories TO ₁ M, TO ₂ M, and in the first and second memories. The scores are stored in the point memories CO ₁ M and CO ₂ M sequentially. Therefore, when these data are printed on the label 29 and issued, it can be done by operating the total key 13 and the print key 11 or the print key 12. Note that the mode changeover switch 8 in this case can be in any position.

First, press the total key 13. Then, in the timer interrupt process, the code data of the total key 13 is stored in the key buffer memory KBM. As a result, in the key processing, the total key flag TOF is set to "1" based on the determination.

Subsequently, either the print key 11 or the print key 12 is pressed. Then, in the timer interrupt process, the code data of the pressed key is stored in the key buffer memory KBM. Accordingly, in the key processing, as a result of the determination of 〓〓, the processing of 〓〓〓 is performed, and then the determination of 〓〓〓〓 is performed. For example, when the print key 12 is pressed, the total key flag TOF is set to "1", so
Next, print the data in the second total memory TO ₂ M and the second point memory CO ₂ M in the buffer memory.
Set the total label to PBM and print the label name of the total label, for example “total”. Buffer memory PBM
After performing the label issuing process (Fig. 10) and resetting the total key flag TOF to "0", the second total memory TO ₂ M and the second
Clear the data of point memory _CO2M . Also, when the print key 11 is pressed, the total key flag TOF is set, so next
1st total memory TO ₁ M and 1st score memory
CO _1M data print buffer memory PBM
After setting, perform the following processing.

According to the above embodiment, when the print key 11 or the print key 12 provided corresponding to a plurality of connectable scales H ₁ and H ₂ is operated, the total key flag TOF is set to the total key flag TOF. 13 is being operated,
When it is determined that the total key 13 has not been operated, the data from the scales H ₁ and H 2 corresponding to the operated print key 11 or ₁₂ is printed on a label 29 and issued, and the print key is 11 or the print key 12 is added to the first total memory TO ₁ M or the second total memory TO ₁ M, and it is determined that the total key 13 is being operated based on the contents of the total key flag TOF. The data from the scales H ₁ and H ₂ corresponding to the operated print key 11 or print key ₂ 12 is displayed on the label 2.
9 and issue the first total memory TO ₁ M or second total memory corresponding to the print key 11 or print key 12.
When it is determined that the total key 13 is operated based on the contents of the total key flag TOF, the operated print key 11 is added to TO ₂ M.
Alternatively, since the data of the first total memory TO ₁ M or the second total memory TO ₂ M corresponding to the print key 12 is printed on the label 29 and issued, multiple scales can be used as H ₁ and H ₂ . Even when configured to be connectable, the total number of keys can be reduced to 131, and therefore the key arrangement on the operation section can be simplified.

Therefore, when issuing a total label, first press the total key 13 and then press the print key 11 or print key 12.
There is no need to provide totalization keys corresponding to the second scales H ₁ and H ₂ respectively.

In the above embodiment, two scales can be connected, but three or more scales may be connected. In this case, the number of print keys, total memories, and point memories must be provided in accordance with the number of connectable scales, but one total key is sufficient.

〔Effect of the invention〕

According to the present invention, when any label issuing key provided corresponding to a plurality of connectable scales is operated, it is determined whether or not the total key is operated based on the content of the determining means. and when it is determined that the total key has not been operated, the data from the scale corresponding to the operated label issuing key is printed and issued on a label, and the total data storage means corresponding to the label issuing key is printed. When it is determined that the total key has been operated based on the contents of the determining means, the data in the total data storage means corresponding to the operated label issuing key is printed and issued on a label. As a result, even if multiple scales are configured to be connectable, only one total key is required, and the total data for each scale can be printed on a label, which simplifies the key layout on the operation panel. can.
