DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label printer which prints, for example, the processing date, expiration date, weight and the like of goods weighed and packaged in a preceding process on a label and issues the label.

[0002]

2. Description of the Related Art A conventional label printer of this type includes a clock IC for outputting a date and a time, and an arithmetic unit (hereinafter referred to as a processing date of an article) for calculating a consumption expiration date from the processing date and the number of expiration days. CPU), a display unit for displaying the product name, processing date, and expiration date (also referred to as the expiration date) of the product, and a printer for printing the product name, processing date, and expiration date. is there.

However, since the above-mentioned conventional label printer is an electronic device, an instantaneous power failure of the power supply during use of the label printer, a journal printer connected to the power line or the label printer (to print the totaled contents, etc.). External printer, etc., may be transmitted from the connection line of the printer, and the date data of the built-in clock IC may change. Therefore, the operator needs to check the date displayed on the display unit when the power of the label printer is turned on, and when printing the processing date on the label, the processing date displayed on the display unit is required. It is necessary to check whether the expiration date is correct. Further, even during use of the label printer, it is necessary to appropriately check whether the processing date and the like displayed on the display unit and the processing date and the like printed (printed) on the label are correct.

[0004]

However, it is difficult for the operator to manage the processing date and expiration date displayed on the display unit and the timing of checking the date printed on the label by the operator himself. It is difficult to ensure completeness due to carelessness, and having the operator check that there is no error in the processing dates printed on all the labels places an excessive burden on the operator. In other words, the conventional label printer does not have a function for allowing the operator to check data on dates such as an incorrect processing date and expiration date at a predetermined timing so that the data is not printed on the label. There is a problem that a function of automatically checking a processing date or the like by itself is not provided.

According to the present invention, there is provided a label printer capable of forcing an operator to check a date such as a processing date and an expiration date, or automatically checking in advance a processing date printed on a label. Another object of the present invention is to provide a label printer in which a function for checking a date is activated when a command to check a date is issued.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a label printer according to the present invention will be described with reference to the drawings. This label printer prints (for example, "printing") the weight of a product weighed and packaged in a previous process, the date of packaging, and the like on a label, and issues the label. The wrapping date refers to a date when an article is packed, for example, and a label is attached to the pack, and is hereinafter referred to as a processing date. FIG. 6 is a block diagram showing an electric circuit of the label printer. CP
The U1, the ROM 2, the RAM 3, the product name master storage unit 4, and the clock unit 9 are electrically connected to each other as shown in FIG. And CPU1, ROM2, RA
The display unit 5, the input unit 6, the printer 7, and the key switch 8 are electrically connected to the M3, the product name master storage unit 4, and the clock unit 9 via I / Os 21 to 24, respectively.

The CPU 1 is a microprocessor for electrically controlling the label printer. ROM
A read-only memory 2 stores a program for operating the label printer. RAM3 is R
It is a random access memory that stores various data obtained by calculating various data as the program stored in the OM 2 progresses, various data, and the like. The product name master storage unit 4 stores a plurality of product name masters including data such as product names, raw materials, additives, contents, and expiration dates in association with a plurality of product name codes. The clock unit 9 can output date and time data according to a program, and can change each data such as date. The display unit 5 displays various data such as a product name code, a product name, a raw material, an additive, a content, a processing date, and a expiration date. The input unit 6 is a keyboard for inputting various data, instructions, and the like. The printer 7 prints various data and the like on a label.

The key switch 8 is a switch for switching the processing mode of the label printer. The processing mode includes a print mode, a storage mode, a program mode,
And aggregation mode. The print mode is a mode for printing desired data or the like on a label. The storage mode is, for example, a mode for registering and changing various data of the product name master. The program mode is a mode for, for example, setting and changing the content to be printed on the label, and changing data of the date, time and time of the clock unit 9. The tabulation mode is a mode for performing, for example, subtotals and totals of items such as weights and amounts, and printing the contents of the tabulation.

FIG. 7 shows the contents of the clock unit 9, which outputs signals representing the year, month, day, hour, minute, and second. For example, a signal representing 98, 08, 01, 15:00, 00 is output at 15:00:00 on August 1, 1998.

FIG. 8 shows registers of date (year, month, day) data and an alarm in the RAM 3. The date register 12 is a register that reads and stores the date data of the clock unit 9 in real time. Hour and minute register 1
Reference numeral 3 denotes a register for reading and storing the hour and minute data of the clock unit 9 in real time. The timing of reading the date data and the hour and minute data is performed by an interrupt program, and the timing of the interrupt is performed by a timer. The time that the label printer prints on the label is up to hours and minutes, and seconds are not printed. Therefore, the interruption timing is set to one second. The expiration date register 14 is a register that stores expiration date data of an article. As for the expiration date data, when a product name code is input (set), the corresponding product name master is read out and included in the product name master. The expiration date register 15 is a register that stores expiration date data. The expiration date data is stored in the date / time data stored in the date / time register 12 and the expiration date register 14 at that time when the CPU 1 reads out the relevant product name master when the product name code is input. This is the time limit calculated from the expiration date data. For example, assuming that the date data is August 1, 1998 and the expiration date is 30 days, the expiration date data is August 30, 1998. One day of the expiration date means the day of the processing day. The timing for calculating the expiration date (timing for updating the data in the expiration date register 15) is as follows: (1) In the state where the expiration date of the product name master is stored in the expiration date register 14, the date is stored in the date register 12. The timing at which data is stored, and (2) the timing at which the expiration date of the product name master is read and the expiration date is stored in the expiration date register 14;
It is.

The first processing date register 16 stores the next (next)
Is a register for storing date data to be printed on the label, ie, processing date data. When a print mode program for printing on a label is executed, the date data stored in the date register 12 is written into the first processing date register 16 before printing on the next label. The second processing date register 17 is a register that stores the processing date data printed on the previous (previous) label. After executing the print mode program and printing the processing date data stored in the first processing date register 16 on the label, the processing date data stored in the first processing date register 16 is stored in the second processing date register 16. It is written into the processing date register 17. The first expiration date register 18 is a register for storing expiration date data to be printed on the next (next) label. When the print mode program is executed, the expiration date data stored in the expiration date register 15 is written to the first expiration date register 18 before printing on the next label. The second expiration date register 19 is a register for storing expiration date data printed on the previous (previous) label. After executing the print mode program and printing the expiration date data stored in the first expiration date register 18 on a label, the expiration date data stored in the first expiration date register 18 is stored in the second expiration date register. It is written to the expiration date register 19. The alarm flag 20 is set in the first and second processing date registers 1
It is determined whether or not the two processing date data stored in the first and second consumption date registers 18 and 1 correspond to each other.
It is determined whether or not the two expiration date data stored in No. 9 match, and when it is determined that they do not match, an error is indicated.

FIG. 9 is a diagram showing the contents of the product name master stored in the product name master storage unit 4. The product name master is
It consists of product name code, product name, raw materials / additives, contents, and expiration date. FIG. 10 is a diagram illustrating the data displayed on the display unit 5 and the calculation results in the print mode. The contents shown in FIG. 10 are displayed when the product name code is input and the process of step S300 shown in FIG. 3 ends. From the top, product name code, product name, raw materials and additives,
Contents, processing date (processing date data stored in first processing date register 16), expiration date, expiration date (consumption expiration data stored in first expiration date register 18), and time (hour) (The time stored in the minute register 13) is displayed. If the label print key (label issue key) of the input unit 6 is pressed while this display is being performed, the contents of this display can be printed on the label.

FIG. 11 shows the display unit 5 displaying the date and time data (data stored in the date and time registers 12 and 13) output by the clock unit 9. This shows a state in which data such as date is displayed for confirmation by an operator. The contents shown in FIG. 11 are (1) when the power is turned on and step S108 shown in FIG. 1 is processed, and (2) when the mode is switched from a mode other than the print mode to the print mode. And the stage at which step S210 is performed. When the power of the label printer is turned on, data such as the date output by the clock unit 9 at the time of the start-up inspection is automatically displayed on the display unit 5, whereby the date is displayed to the operator. And so on can be forcibly determined whether or not the data is correct. The time when the mode is switched from the mode other than the print mode to the print mode is determined by the clock unit 9.
Since the data such as the date can be rewritten in the program mode, when the mode is switched from the mode other than the print mode to the print mode, the data such as the date may be rewritten. At this time,
It is possible to force the operator to determine whether the data such as the date is correct. Then, as shown in FIG. 11, a message indicating that the content of the determination as to whether the data such as the date is correct is displayed together with the data such as the date. At this time, even if the user operates keys other than the Yes key (the label issuing key of the input unit 6) and the No key (the erase key of the input unit 6), no command can be input. The determination of the data such as the date can be reliably performed, and the necessary correction of the data such as the date can be reliably performed. When the user presses the Yes key of the input unit 6, the user can proceed to a stage (step) where printing can be performed on a label. However, when the user presses the No key, the clock unit 9 is instructed to change the date, time, and time data. Is displayed on the display unit 5 (S11).
4, S220). If the date and time data of the clock unit 9 is changed by switching to the program mode, the contents shown in FIG. 11 are displayed on the display unit 5 when returning to the print mode (S210), and the changed date is changed. You can check the date and time data.

FIG. 13 shows a case where the product name code is inputted after the data such as the date of the clock section 9 is changed, and the step S is executed.
The display of the processing date and the expiration date data on the display unit 5 at the stage 414 indicates that the operator can forcibly determine whether the processing date and the expiration date data are correct. I can do it. Step S4
At 16, it is determined whether or not the confirmation key has been pressed. This determination is made when the date data of the clock unit 9 has not been changed (the figure in which the confirmation key is displayed is shown in the figure). Absent.). However, when the date data of the clock unit 9 has been changed, as shown in FIG. 13, a Yes key or a No key for inputting the content of determination as to whether the processing date and the expiration date data are correct is input. A message to the effect that the key is pressed is displayed (not shown in the flowchart).

FIG. 14 is a diagram showing the contents displayed on the display unit 5 when the warning flag 20 is turned on in the print mode. In other words, the immediately preceding label print data is the second processing date register and the expiration date register 17,
The processing date and the expiration date data stored in No. 19 are data already printed on the previous label. The label print data is the processing date and the expiration date data stored in the first processing date register and the expiration date registers 16 and 18, and is the data to be printed on the next label. FIG. 14 shows a state in which the processing date of the label print data should be "August" but has been changed to "September" due to, for example, external noise. In other words, when data having the same processing date and expiration date are sequentially printed on a predetermined number of labels, the processing date or expiration date data to be printed on the next label differs from the data printed on the previous label. When the data is present, the display shown in FIG. 14 is displayed, and the operator can be warned to correct the incorrect data. Then, when this display is made, the printing can be automatically interrupted so that incorrect data is not printed on the label. Also,
When the label printer is used at midnight and the date and time data (date) of the clock unit 9 is changed and the processing date and expiration date data are changed, the display shown in FIG. 15 is performed and the changed date is displayed. The contents can be notified to the worker.

The contents displayed by the display means according to the first aspect are as shown in FIG. 11, and the judgment input means is the input section 6. The instructing means for instructing whether or not to check the date according to claim 2 is a step S10 shown in FIG.
6, and corresponds to each step of step S206 shown in FIG. 2, and the content of the command as to whether or not to check in each step is set by the operator operating the input unit 6 in advance. The print determining means according to the third aspect includes a step S112 shown in FIG. 1 and a step S112 shown in FIG.
214 corresponds to each step. This print determination means is provided when the determination content indicating that the date and time shown in FIGS. 11 and 13 and the like displayed on the display unit 5 are correct is input by the input unit 6, or when the date and time are determined. Is a means for enabling data including a correct date and the like or a date and time after the change to be printed on a label when is changed.

The storage means according to the fourth aspect comprises the first and second processing date registers 16, 17 shown in FIG.
And the second expiration date registers 18 and 19, and the date determination means performs steps S508 and S5 shown in FIG.
It corresponds to each step of 10. The date determining means determines whether or not the two processing date data stored in the first and second processing date registers 16 and 17 match (S508), and the first and second consumptions. Deadline register 1
This is a means for determining whether or not the two expiration date data stored in Nos. 8 and 19 match (S510). The contents displayed by the display means according to claim 5 are shown in FIGS.
5, and this display is performed in step S shown in FIG.
520 is displayed when it is processed. Step S52
0 is the first and second processing date registers 1
When it is determined that the two processing date data stored in 6, 6 and 17 do not match, or when the two consumption date data stored in the first and second consumption time registers 18 and 19 match. 14 and 15 when it is determined that there is no
As shown in (2), this is a step of performing processing for displaying the previous and next processing date data and each expiration date data. Then, as shown in FIGS. 14 and 15, the area of the processing date and the consumption period to be confirmed is shaded and displayed so as to be conspicuous, so that the operator can easily confirm the area.
In the display shown in FIG. 13 as well, regions of the processing date and the consumption period to be confirmed are shaded so as to be conspicuous. Instead of shading, the area to be checked may be surrounded by a frame, black-and-white inverted display may be performed, or the area and another area may be color-coded.

Next, the procedure for printing predetermined contents on a label by the label printer configured as described above, and checking the date, time, processing date, and expiration date will be described.
This will be described with reference to the flowcharts shown in FIGS. FIG. 1 shows a procedure for checking the date and time data of the clock unit 9 when the power of the label printer is turned on. First, when the operator turns on the power (S10
0), CPU 1 has I / Os 21 to 24, registers 12 to 1
9 is initialized (S102). Next, the CPU 1 writes the date and time data of the clock unit 9 to the date register 12 and the hour and minute register 13 (S104). Then, it is determined whether a date check command has been issued (S106). If the date check command has been issued and YES is determined, the date and time shown in FIG. The contents representing the date, time, and the like are displayed (S108). In a state where the display unit 5 displays the date, time, and the like shown in FIG. 11, the operator determines (checks) whether data such as the date is correct, and the operator presses the Yes key (label issuance). Key 1) or No key (delete key), the CPU 1 cannot perform the next process. If the operator determines that the date is correct and presses the Yes key, the process proceeds to step S200 (S110, S112). ).

However, in step S106, when the date check command (setting) has not been issued and the determination is NO, the date and time are not displayed and the next step S200 is not performed.
Proceed to. Then, in step S112, when the operator determines that the data such as the date is incorrect and presses the No key, the display unit 5 should adjust the data such as the date as shown in FIG. Message to the effect is displayed in step S2.
Go to 00 (S114). As described above, when the power of the label printer is turned on, it is possible to force the operator to determine whether the data such as the date of the clock unit 5 is correct. In addition, it is possible to reliably check data such as the date without having to rely on the attention of the operator.

Next, the CPU 1 determines whether or not the position of the key switch 8 is in the print mode (S200).
That is, in step S112, when the operator determines that the date is incorrect, and presses the No key, the operator operates the key switch 8 in order to adjust data such as the date of the clock unit 9. Although it is necessary to set the position to the program mode, if the operator determines in step S112 that the date is correct and presses the Yes key, the data such as the date is printed on the label. Since it is possible, the position of the key switch 8 is set to the print mode. Here, first, in step S112, a procedure will be described in which the operator presses the No key, sets the position of the key switch 8 to the program mode, and adjusts data such as the date and time of the clock unit 9. Therefore, in step S200, the CPU 1 determines NO, and the operator adjusts data such as the date of the clock unit 9 in the program mode (S202). When the adjustment is completed, the CPU 1 sets the date check flag (FIG. (Not shown)
N (S204), and the process returns to step S200.

Now that the adjustment of the data such as the date of the clock section 9 has been completed, the operator switches the position of the key switch 8 to the print mode (S200). Then, YES is determined in step S200, and since the date check is performed, YES is determined in step S206, and it is determined whether the date check flag is ON (S208). It is determined whether or not the date check flag is ON. If the date check flag is ON and the determination is YES, there is a possibility that data such as the date of the clock unit 9 has been adjusted. This is so that in the next steps S210 to S214, a process of determining whether or not data such as the date is correct can be performed. If the date check flag is OFF and the determination is NO, the data such as the date is determined (checked) in steps S108 to S112. (S21).
8) to be able to do so.

The processing in steps S210 to S214 is the same as the processing in steps S108 to S112, and a description thereof will be omitted. Then, in step S214, the operator determines that the data such as the date is correct and Y
If the es key is pressed and the CPU 1 determines YES, the date check flag is turned off (S216), and a process of printing data such as the date on the label is performed (S21).
8) Return to step S200. Step S21
In 4, when the operator determines that the data such as the date is incorrect and presses the No key, and the CPU 1 determines NO, the display unit 5 displays the data such as the date as shown in FIG. Is displayed and a message to the effect that adjustment should be performed is displayed (step S20).
Go to 0 (S220). Then, in the same manner as described above, adjustment of data such as the date of the clock unit 9 is performed in step S202. As described above, when the position of the key switch 8 is switched from a mode other than the print mode to the print mode, the operator is forcibly determined whether the data such as the date of the clock unit 5 is correct. , The data such as the date can be surely checked without depending on the attention of the operator.

Next, step S218 for printing on a label
The contents of the process will be described with reference to FIG. First, the operator operates the input unit 6 to input the content and format of data to be printed, such as the product name code of the product to be printed (S
300). Then, the number of labels to be printed (printed) is set, and the label print key is pressed (S302, S30).
4). The label print key is a command key for starting printing. Then, the CPU 1 determines whether or not the remaining number of labels to be printed is 0 (S306).
When it is determined that the number of remaining labels is not 0 and NO, it is determined whether or not the automatic printing is set (S30).
8). This label printer has an automatic print setting that automatically prints a predetermined number of labels continuously and automatically, and prints one label each time an operator presses a label issuing key.
There is a manual print setting for printing one sheet at a time, and these settings can be set in advance. That is, step S
In 308, if the CPU 1 is set to automatic printing and determines YES, it is determined whether or not the previously printed label has been peeled from the backing sheet so that the printed label can be sent out (S312). When the printed label has been peeled off from the backing paper and the determination is YES, printing is performed on the current label, and the printed label is sent out (S314). Then, the remaining number of labels to be printed is calculated by subtracting the number of printed labels from the preset number of labels to be printed (S316). Thereafter, the process returns to step S306 to determine whether or not the remaining number of labels is 0, and prints on the label in the same manner as described above until the remaining number of labels becomes 0 (S306 to S316). When the number of sheets reaches 0, printing is terminated, and the process proceeds to step S200 shown in FIG.

However, if it is determined in step S308 that manual printing has been set and NO is determined, it is determined whether or not the label issuing key has been pressed by the operator (step S308).
310) After the label issuance key is pressed, in the same manner as in the case of automatic printing, after the previous printed label is separated from the backing paper, the subsequent processes are sequentially performed. In this manner, printing can be performed on the label.

Next, the contents of the processing performed by the CPU 1 when the operator inputs data such as the article name code of the article to be printed, that is, the contents of step S300 will be described with reference to FIG. First, when an operator inputs a product name code (S400), the CPU 1 searches for the product name code from those stored in the product name master storage unit 4 (S4).
02). Then, as a result of the search, it is determined whether or not the data of the product name code exists (S404). If the data exists and the determination is YES, the data of the product name master corresponding to the product name code is read (S406). If no data exists and the determination is NO, the program is terminated. Then, another item name code can be input.
When the data of the item name master is read, the read data is stored in the corresponding registers, and the expiration date is written in the expiration date register 14 (S408). Then, the expiration date is calculated by adding the date data and the expiration date data stored in the date register 12 and the expiration date register 14, and the calculated expiration date data is written to the expiration date register 15 ( S
410).

Next, it is determined whether or not the date is set to be checked (S412). If the date is not set to be checked and the determination is NO, the date and time of the clock unit 9 are determined. Then, the processing after step S302 shown in FIG. 3 is performed without displaying and checking the time data.
Then, in step S412, when the date is set to be checked and the determination is YES, the date, time and time data of the clock unit 9 are displayed on the display unit 5 (S4).
14). Next, the operator determines whether or not the displayed data such as the date is correct, determines that the data is correct, and presses the confirmation key of the input unit 6, and the CPU 1 erases the date and time display. The contents of the product name master shown in FIG. 10 are displayed on the display unit 5 (S416, S418), and after that, in step S3
Go to 02. However, in step S414, the date, time, and time data of the clock unit 9 are displayed on the display unit 5, and the display content is "Please press the Yes key or No key" in the content shown in FIG. Instead, a message "Please press the confirmation key." Is displayed (not shown). If the operator determines that the displayed data such as the date is incorrect, the operator can switch to the program mode and adjust the data such as the date of the clock unit 9. And in this way,
When the product name code is input after the date data of the clock unit 9 is changed, the processing date and expiration date data are displayed on the display unit 5 at the stage of step S414, as shown in FIG.

Next, the procedure in which the CPU 1 prints data such as the processing date on a label and the procedure in which the processing date and the like are checked, that is, the contents of step S314 will be described with reference to FIG. First, the CPU 1 writes the date and time data stored in the date and time register 12 into the first processing date register 16 (S500), and writes the expiration date data stored in the expiration date register 15 into the first expiration date. Register 18
(S502). Then, it is determined whether or not the date is set to be checked (S50).
4) It is determined whether or not it is set to print a date (year / month / day data such as a processing date) (S506).
Here, the date is not set to be checked and N
If it is determined to be O, or if it is determined that the date is not set to be printed and the determination is NO, the process proceeds to step S508.
Then, processing such as printing after the next step S512 is performed without checking the processing date and the expiration date data in S510. In steps S504 and S506, the date is set to be checked, and
The date is set to be printed.
When it is determined as ES, it is determined whether or not the two processing date data stored in the first and second processing date registers 16 and 17 match (S508). Then, when the two processing date data are coincident and YES is determined, it is determined whether the two consumption date data stored in the first and second expiration date registers 18 and 19 match. A determination is made (S510). Then, when the first and second processing date data coincide with each other and the determination is YES, and when the first and second consumption date data coincide with each other and the determination is YES, for example, a predetermined value is set. The data having the contents shown in FIG. 10 is printed on a label (S512). However, when the first and second processing date data do not match and thus the determination is NO, or when the first and second consumption date data do not match and the determination is NO, the alarm flag is turned on. (S5
18) Then, for example, the contents shown in FIG. 14 are displayed on the display unit 5 and the program is terminated. Then, after switching to the program mode and adjusting data such as the date of the clock unit 9, printing can be performed on the label.

Thus, the processing date and expiration date data to be printed on the next label stored in the first processing date register 16 and the expiration date register 18 and the second processing date register 17 and the expiration date data It is determined whether the processing date and the expiration date data printed on the previous label stored in the register 19 correspond to each other, and whether the corresponding processing date and the expiration date data correspond to each other. Since the data is printed on the label when the items match each other, the processing date and expiration date data can be checked for each label,
The correct processing date and expiration date data can always be printed on the label. Therefore, for example, when the same processing date or the like is printed on a plurality of labels, the data of the processing date or the like stored in the first and second processing date registers 16 and 17 due to external noise or the like. When the corresponding items do not match each other, the abnormality can be automatically detected, the printing of the label can be interrupted, and the abnormality can be displayed on the display unit 5 to notify the operator. When notifying an abnormality, as shown in FIGS. 13 to 15, the area for displaying the data of the processing date and the consumption period to be confirmed is shaded or black-and-white inverted so as to be conspicuous. To the operator.

Then, after the printing process is performed in step S512, the currently printed processing date data stored in the first processing date register 16 is written to the second processing date register 17 (S514), and The first expiration date data stored in the first expiration date register 18 is written into the second expiration date register 19 (S
516). Thereafter, the process proceeds to step S316 to perform the processing of each step.

Steps S106, S206, S4
In S12 and S504, it is determined whether or not the setting for checking the date is made. If the setting for checking the date is not made, data such as the processing date is not displayed on the display unit 5. In this case, the label printer can sequentially advance the steps of the printing process without the operator performing unnecessary check of the data such as the processing date, and the printing time can be reduced.
Further, in step S506, it is determined whether or not the date printing is set. Therefore, even if the date is set to be checked, when the date is not printed, unnecessary date checking is not performed. Then, the steps of the printing process of the label printer can be sequentially performed.

According to the first aspect of the present invention, the display means displays the date and time representing the date, and the timing for displaying that the content of the determination as to whether or not the date is correct should be input to the label printer. The time when the power is turned on when starting to use may be that the date and time changed from the actual date to the actual date when using the previous label printer, This is because the date may have been changed due to extraneous noise during use.
When the operator switches from a mode other than the print mode to the print mode in order to use the print mode, the operator changes the date and time in a mode other than the print mode. This is in order to be able to confirm the date and time when the date was set. As described above, at each of the above-mentioned timings, the display means displays the date and the display automatically indicates that the content of the determination as to whether or not the date is correct should be input. You do n’t need to control when
Therefore, it is possible to force the operator to check the date, and as a result, it is possible to prevent the wrong date from being printed on the label.

According to the second aspect of the invention, for example, when printing the date on a label, the command means issues a command to check the date, whereby the display means displays the date and time. It indicates that the content of the determination as to whether or not the date is correct should be input. In this way, when printing the date on the label, the operator can surely check the date by following the display on the display means. Then, for example, when the date is not printed on the label, the instruction means is made to issue a command not to check the date, so that the display means does not display that the date and the judgment content should be input. Therefore, the worker does not need to check the date and time, so the work is simple, and the label printer can sequentially proceed with the process for printing on the label, and the printing time can be reduced.

According to the third aspect of the present invention, the judgment content indicating that the date displayed on the display means is correct is input,
Alternatively, when it is determined by the print determination unit that the date has been changed, it is possible to print data including the date on the label. In other words, if the user inputs the determination that the date displayed on the display means is incorrect, data including the date cannot be printed on the label until the incorrect date is changed. Therefore, the correct date can always be printed on the label.

According to a fourth aspect of the invention, every time data including a date is printed on a label, the date printed on the previous label and the data scheduled to be printed on the next label coincide with each other. This is a configuration in which it is possible to successively determine whether or not the operation is performed by the date determining means. Therefore, for example, while data including the date is sequentially printed on the label by the label printer, even if the date is changed in a state where the operator does not notice due to external noise, the change is automatically performed. The date determination means can surely make the determination. Thus, according to the label printer, the date printed on the label is automatically checked for each label, so that incorrect date data can be prevented from being printed on the label.

According to the fifth aspect of the present invention, when the date determining means determines that the data of the previous month and the data of the next month do not coincide with each other, the data of the previous month and the next month are not used. Can be displayed on the display means, so that the operator can easily check the different data of each previous and next month displayed on the display means. Therefore, if the next month's date is incorrect,
The data can be surely changed.

According to the sixth invention, by applying the first to fifth inventions to a label printer capable of printing data of the processing date and the expiration date on a label, the processed product can An incorrect processing date and expiration date can be prevented from being printed, thereby maintaining the business credibility of the person who sells the item with this label.
