Abstract

PURPOSE:To temporarily change a valid date per product according to temporary change of processing date improving operativity by a method wherein difference between the changed processing date and the current date counted by a counting circuit is calculated, and a valid term of a valid term storing unit is automatically corrected based on the difference. CONSTITUTION:When a PLU code is registered and a PLU key 18c is operated to specify a product at first, the name, unit price and valid term of the product are read out and the valid term is stored in a valid term memory 13b. If operation of temporarily changing processing date is done in this state, the contents of a treatment date memory 13a is changed as well as valid term correcting data for the current date is calculated and stored in a term correcting memory 13c. At this time if change able/unable status of the specified product is able, the valid term of the valid term memory 13b is changed based on the contents of the term correcting memory 13c and re-stored in the valid term memory 13b. Then the product is weighed and a label is issued according to the input of an issue key 18d.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a label printer.

[Industrial Application Field 1 For example, a weighing label printer has a scale, and when a product code is entered from the keyboard, the preset product name, unit price, expiration date, etc. are read out, and in this state, the product is read out from the scale. When the weight value is imported, the price is calculated from the weight value and unit price, and the product name, unit price, and
Labels are printed with the weight value, price, expiration date, and preset processing date printed on each label.

Conventionally, such weighing label printers have a built-in clock circuit to automatically update the processing date. Additionally, a function to temporarily change the processing date is provided, and it is possible to shift the processing date temporally by manual setting. That is, for example, if a label is to be issued in advance for a product to be sold the next day, it is preferable for the store to set the processing date to the same day rather than the day before the sale date, and the processing date change function is used in such a case. However, since the expiry date of each product is set in advance, for example, if you change the processing date of a product that was processed on the same day to the next day, the expiration date printed on the label will be extended by one day than it actually is, which is a problem. .

Therefore, such weighing label printers have conventionally been provided with a function to temporarily change the validity period, so that when changing the processing date of a product processed on the same day, the validity period can also be changed manually at the same time.

[Problems to be Solved by the Invention] As mentioned above, in the conventional technology, when the processing date is changed manually, the validity period must also be changed manually at the same time, and the validity period differs for each product. The validity period must be changed on a unit-by-unit basis, which is cumbersome and causes a decrease in work efficiency, especially when pricing products at a mass retailer or the like.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a label printer that can automatically temporarily change the effective date of each product when the processing date is temporarily changed, thereby improving operability.

Another object of the present invention is to provide a label printer that can select whether or not to automatically change the validity period in response to a temporary change in the processing date, thereby improving its practicality.

[Means for Solving the Problems] The present invention stores the date measured by a clock circuit in a processing date storage unit, stores the set validity period in a validity period storage unit, and stores the date measured by a clock circuit in a validity period storage unit, and stores the date on a label paper together with the product name and price. In a label printer that prints a processing date in a processing date storage section and a validity period in a validity period storage section and issues a label, there is provided a processing date changing means for temporarily changing the date in the processing date storage section, and a date changed by this means. It is equipped with a calculation means for calculating the difference between the date and the date measured by the clock circuit, and a validity period correction means for correcting the validity period in the validity period storage unit based on the difference calculated by the calculation means. be.

It is convenient to provide a selection means for selecting whether or not to correct the validity period by the validity period correction means.

Further, a product unit selection unit may be provided for selecting whether or not to correct the validity period by the validity period correction unit for each product.

[Operation] In the present invention having such a configuration, when the processing date in the processing date storage section is temporarily changed by the processing date changing means, the changed processing date and the current date measured by the clock circuit are changed. The difference is calculated, and the validity period in the validity period storage section is automatically corrected based on the difference. For example, if the modified processing date is one day later than the current date, the validity period will be shortened by one day.

By providing a selection means, it is possible to arbitrarily select whether or not to automatically change the validity period in conjunction with a temporary change in the processing date.

Further, by providing a product unit selection means, products whose validity period is automatically changed can be distinguished from products whose validity period is not automatically changed.

[Example] Hereinafter, an example of the present invention will be described using the drawings. In this embodiment, the present invention will be described as applied to a weighing label printer.

FIG. 1 is a block diagram of a weighing label printer, in which 11 is a microprocessor constituting the main body of the control unit;
2. Corresponding to the PLU (Price Look Up) code attached to each product, the product name, unit price per unit weight, validity period, etc., and whether or not the validity period will be changed due to a temporary change in the processing date. 13 is a RAM with various memories for data processing; 14 is a clock circuit that measures time and date; 15
is an A/D (analog/digital) converter that converts the weighing signal from the weighing section 16 into a digital count value. Further, 17 is a keyboard controller that receives key signals from the keyboard 18, 19 is a display controller that controls the display 20 and outputs display data to the display 20, and 21 is a controller that controls the printing section 22 and prints on the printing section 22. This is a print controller that outputs data.

The microprocessor 11, the PLU file 12, the RAM 13, and each controller 17, 19 .
21 is electrically connected via a pass line 23. Further, the microprocessor 11 includes the clock circuit 1
In addition to importing date and time data from 4,
The count value is taken in from the /D converter 15 at a predetermined timing by an interrupt.

The keyboard 18 has "0" as shown in FIG.
~ "9" numeric key 18a1 Clear key 18b used for clearing numeric values, PLU key 18C used for inputting PLU code, issue key 18 for specifying label issue
Temporary change key 18e used to temporarily change the d1 processing date
Various keys such as a date key 18f and a date key 18f are provided.

The display 20 is composed of a plurality of segment display elements that electrically display numerical data such as a PLU code, unit price, weight value, price, date of processing, and period of validity.

The printing unit 22 prints on the label paper being conveyed, and issues the label from the label issuing port.

As shown in FIG. 3, the RAM 13 includes a processing date memory 13a for storing the processing date, a validity period memory 13b for storing the validity period, a period correction memory 13c for storing correction data for the validity period, PLU code, product name, and unit price. 1
Temporary buffer 13d used for temporarily storing data such as weight values and prices; Print buffer 13e for storing print data; Display buffer 13f1 for storing display data.
Processing date change flag F1 is set (1) when the processing date is temporarily changed; Validity period change prohibition flag F2 is set (1) when automatic change of validity period is not possible; PL
A flag memory 13g and the like are formed in which flag information such as a read flag FB is set (1) when product information is read out by designation of the U code.

Thus, the microprocessor 1.1 stores the date counted by the clock circuit 14 as the processing date in the processing date memory 13a. However, processing date change flag F1
If is set, the processing date will not be updated.

Further, when the microprocessor 11 receives a key signal from the keyboard 18, it executes processing according to the key signal.

FIG. 4 shows key processing of the temporary change key 18e.
When you start the flowchart, press number key 18a or clear key 1.
Waiting for 8b's manpower. Here, if the clear key 18b is input without a numeric value being entered using the numeric key 18a, the processing date change flag F1 is reset (to 0) and this process is terminated.

On the other hand, if the clear key 18b is manually operated after the numeric value has been entered using the numeric key 18a, the numeric data is cleared and the system waits for manual input of the numeric key 18a or the clear key 18b.

On the other hand, when a number is entered using the number key 18a and then the date key 18f is input, it is determined that the entered number data (with a limit on the number of digits) is the processing date, and the contents of the processing date memory 13a are Change to the input processing date. Next, the date measured by the clock circuit 14 is read out, and the difference between it and the entered processing date is calculated, and the result is stored in the period correction memory 13c as valid period correction data. Also, a processing date change flag F1 is set.

Next, the state of the read flag F3 is checked. . ,here,
If this flag F3 is reset, no product has been designated yet, so the content of the processing date memory 13a, that is, the temporarily changed processing date is displayed on the display 20 and the process is terminated.

On the other hand, if the read flag F3 is set, it means that the product has already been specified, and therefore the state of the valid period unchangeable flag F2 is checked. Here, this flag F2
is set, the effective period will not be automatically changed due to the temporary change of the processing date, so the processing date after the temporary change in the processing date memory 13a is displayed on the display 20 and this process is executed. finish.

On the other hand, if the validity period cannot be changed flag F2 is reset, the automatic time change of the validity period is executed in conjunction with the temporary change of the processing date, so the contents of the validity period memory 13b are based on the contents of the period correction memory 13c. and the result is stored again in the valid period memory 13b. Thereafter, the content of the valid period memory 13b, that is, the corrected valid period is displayed on the display 20. Further, the processing date after the temporary change in the processing date memory 13a is also displayed on the display 20, and this processing is completed.

FIG. 5 shows the key processing of the PLU key 18c. When the flowchart starts, after confirming that a number has been set using the numeric key 18a immediately before, the numeric data (with a limit on the number of digits) is displayed. Reads the corresponding product setting information from the PLU file 12 as the PLU code of the specified product, and
Code, product name.

The unit price is stored in the temporary buffer 13e. Next, the state of the processing date change flag F1 is checked. And this flag F1
If is set, the processing date has been temporarily changed, so the change permission status read from the PLU file 12 is checked.

Here, if the status is changeable, the same < P
The valid period read from the LU file 12 is corrected based on the contents of the period correction memory 13c, and the result is stored in the valid period memory 13b. After that, - time buffer 13d P
The display 20 displays the LU code, product name, unit price, processing date in the processing date memory 13a, and validity period in the validity period memory 13b.
The readout flag F3 is set, and this process ends.

On the other hand, if the status cannot be changed, the valid period cannot be changed flag F2 is set, and the valid period read from the PLU file 12 is stored as is in the valid period memory 13b. After that, the PLU code, product name, unit price, processing date, and validity period are displayed on the display 20, and
The read flag F3 is set and this process ends.

On the other hand, when the processing date change flag F1 has been reset, the state of the changeability status is similarly checked. Then, only when the status indicates that the status cannot be changed, the valid period cannot be changed flag F2 is set. Thereafter, the validity period read from the PLU file 12 is stored as is in the validity period memory 13b, the PLU code, product name, unit price, processing date, and validity period are displayed on the display 20, and the read flag F
3 is set, and this process ends.

In this state, the weighing unit 16 weighs the product, and when the count value for the weighing is taken in from the A/D converter 15, the microprocessor 11 converts the count value into a weight value in duram units, for example. A price is calculated from the weight value and the unit price read from the PLU file 12 and stored in the -hour buffer 13d, and the weight value and price are displayed on the display 20.

FIG. 6 shows the key processing of the issue key 18d. After starting the flowchart and confirming that the read flag F3 is set, the product name, unit price, weight value, price, and processing of the time buffer 13d are entered. The processing date in the date memory 13a and the validity period in the validity period memory 13b are stored in the print buffer 13.
e, and the printing section 22 prints on label paper to issue a label 70 as shown in FIG. 7, for example. When the preset number of labels 70 have been issued, the validity period cannot be changed flag F2 and the read flag F3.
Reset and end this process.

In this embodiment with such a configuration, for example, if the processing date is to be advanced by one day to the next day when pricing a weighed product to be sold the next day, first press the - hour change key 18e.
, then enter the changed processing date using the numeric key 18a, and then operate the date key 18f. Then, the processing date memory 13a in which the date of the clock circuit 14 was stored in advance.
The contents will be temporarily changed to the date the number was entered. Further, the current date of the clock circuit 14 is read out, the difference between this current date and the entered date is calculated, and the difference (in this case, one day later) is stored in the period correction memory 13c. At this time, the changed processing date is displayed on the display 20 so that it can be confirmed.

Next, the PLU code of the product to be priced is entered using the number keys 18a, and the PLO key 18c is operated. Then, the corresponding product name, unit price, validity period, changeability status, etc. are read out from the PLU file 12. here,
If the status indicates that the validity period can be changed,
It is necessary to correct the validity period of the product due to the temporary change in the processing date, so the validity period of the product is temporarily changed to 2' based on the contents of the period correction memory 13c. The validity period is stored in the validity period memory 13b. For example, if the validity period of the product is 7 days and the correction data in the period correction memory 13c is 1 day later,
The validity period is 6 days.

In this case, the date one day after the actual processing date is printed on the label as the processing date, and the validity period is from the actual processing date, so the product information on the label is accurate.

On the other hand, if the changeability status indicates that change is not possible,
Since the product does not require correction of the validity period even if the processing date is temporarily changed, the preset validity period is stored in the validity period memory 13b.

The product name, unit price, processing date, and effective date are displayed on the display 20.

In this state, when the weighing unit 16 weighs the product, a count value corresponding to the weighing of the product is taken in from the A/D converter 15. The count value is then converted to a weight value,
A price is calculated from the weight value and unit price, and the weight value and price are displayed on the display 20.

After that, the issue key 18d is operated. By doing so, the product name, unit price, weight value, price, processing date, and expiration date are printed on the label paper by the printing unit 22, and a label 70 as shown in FIG. 7 is issued from the label issuing port. The issued label 70 is then affixed to the weighed product. Also, the weight value and price at this time are P
The cumulative total is registered in the cumulative total area corresponding to the input PLU code of the LU file 12.

Thereafter, by inputting the PLO code again and specifying the product, a label for the specified product is issued with the processing date changed and the validity period corrected as necessary.

In addition, in order to cancel the temporary change state of the processing date, it is sufficient to operate the - hour change key 182 and then input the clear key 18b. By doing so, the current date is read from the clock circuit 14 at a predetermined timing, and this date is stored in the processing date memory 13a as the processing date.

Furthermore, in this embodiment, after specifying a product, it is also possible to temporarily change the processing date. That is, at the beginning P
When the LU code is entered and the PLU key 18c is operated to specify a product, the product name, unit price, period of validity, etc. are read out, and the period of validity is stored in the period of validity memory 13b. If the processing date is temporarily changed in this state, the contents of the processing date memory 13a are changed, and valid period correction data for the current date is calculated and stored in the period correction memory 13c. At this time, if the changeability status of the specified product is changeable, that is, if the validity period cannot be changed flag F2 is reset, the validity period of the validity period memory 13b is changed based on the contents of the period correction memory 13c, and the validity period is It is stored again in the period memory 13b. Thereafter, the product is weighed and a label is issued in response to the input of the issue key 18d, as described above.

In this manner, according to this embodiment, when the processing date is temporarily changed, the preset validity period of the designated product is automatically corrected based on the change. Therefore, there is no need to change the validity period, which simplifies the operation and improves work efficiency.

Furthermore, since the operator will not forget to change the validity period due to a temporary change in the processing date, it is possible to always issue labels with accurate product information printed on them.

Further, by setting a status indicating whether or not the validity period can be changed for each product in the PLU file 12, it is possible to distinguish between products whose validity period will be changed due to a temporary change in the processing date and products whose validity period will not be changed.

In addition, in the above-mentioned embodiment, the application was described to be applied to a weighing label printer that issues labels while weighing by connecting a weighing section, but the present invention is not necessarily limited to this.
The present invention can also be applied to a label printer that does not have a weighing unit connected and issues labels only by manual input of keys or data input from the outside.

Further, in the embodiment described above, the changeability status of the PLU file 12 and the validity period changeability flag F2 may be omitted. In this case, when the processing date is temporarily changed, all the validity periods of the designated products are automatically changed, but the effects of the present invention are still fully exerted.

Furthermore, in the above embodiment, the validity period cannot be changed flag F
A means for forcibly setting or resetting 2 may be provided. By doing so, it becomes possible to select whether or not to automatically change the validity period in conjunction with a temporary change in the processing date for all products, rather than for each product. Further, in this case, there is no problem even if the changeability status for each product is omitted.

In addition, it goes without saying that various modifications can be made to the operating procedure for temporarily changing the processing date, etc., without departing from the gist of the present invention.

[Effects of the Invention] As detailed above, according to the present invention, the effective date of each product can be automatically temporarily changed in accordance with the temporary change of the processing date, and the label can improve operability. We can provide printers.

According to the second aspect of the invention, it is possible to provide a label printer that can select whether or not to automatically change the validity period in response to a temporary change in the processing date, thereby improving practicality.

Furthermore, according to claim 3, it is possible to provide a label printer in which whether or not to automatically change the validity period can be set for each product.
