Description

  The present invention relates to a label printer applicable to display label production such as a confectionery box. Specifically, the storage device stores a minimum number of days and a maximum number of days as an effective number of days for each item, and includes a control unit that reads out the minimum number of days and the maximum number of days corresponding to the input item name. Display label based on the result of comparing the entered effective date with the date added with the minimum number of days read out on the starting date and the date added with the maximum number of days read out on the starting date In addition to making it possible to detect in advance an effective date erroneous input, it is possible to prevent erroneous display of an effective date due to a display label.

  Usually, the display label which shows merchandise information, such as a name, a raw material name, and a shelf life, is stuck to the foodstuff sold at a shop front. The content displayed on the display label is regulated by the Food Sanitation Law, JAS Law, etc., and displaying product information that violates the regulation, for example, displaying a shelf life longer than the regulation, may cause penalties and at the same time It will damage the trust, and thus the trust of the manufacturer and the seller.

  In addition, display labels are produced and affixed in various distribution processes such as manufacturing, processing, and sales, depending on the nature of the food product and the sales method. For example, in the case of boxed confectionery sold in various combinations at a retail store, a retail store operator often produces display labels.

  For the production of the display label, a label printer or the like is used. The label printer is a device that prints information input directly from an input unit or information input from a personal computer or a medium on a dedicated label sheet. In the production process of the display label by the label printer, there is a problem that the effective date of the product such as the expiration date or the expiration date is often manually input by the operator, and erroneous input is likely to occur.

  In relation to this, an electronic balance (label printer) having a label issuing function as shown in Patent Document 1 is disclosed. The label printer includes a clock unit, an operation unit that sets the effective date (period) of the product, and a control unit that calculates the effective date of the product from the effective date set by the operation unit. With this configuration, the processing date of the product can be automatically printed on the label based on the clock content of the clock unit, so that the operator does not have to make daily updates and there is no mistake.

  A label issuing machine as shown in Patent Document 2 is also disclosed. According to this label issuing machine, an electronic timepiece having a clock function, a memory, and a date calculating means are provided, and even if the processing date does not coincide with the label issuing date, the date managed by the timing means is used as a reference. The effective date is calculated. Therefore, even when it is desired to intentionally shift the effective date forward, it is not necessary to calculate the period.

  A time limit display device as shown in Patent Document 3 is also disclosed. According to this time limit display device, a storage means for storing a predetermined calculation date and period, and a date having a difference from the calculation date for the period based on the calculation date and the period stored in the storage means as the expiration date And a deadline date calculation means to be obtained. With this configuration, it is possible to easily and surely know the day when a predetermined period has elapsed from the starting date, by simply inputting the number of days in a desired period. By using this in place of manual calculation by a calendar or the like when calculating the expiration date, it is possible to prevent an error in counting the number of days in the expiration period.

  On the other hand, a printing apparatus as shown in Patent Document 4 is also disclosed. According to this printing apparatus, the radio timepiece is mounted on the printer, and the functions that can be operated by the user with respect to the radio timepiece are limited only to forcibly reinforcing the timer with the standard radio wave. In this way, the user can only forcibly correct the timer using the standard radio wave by operating the adjustment button, and cannot set an arbitrary date or time. That is, the correction of the time by the user can be made unnecessary. Thereby, it becomes possible to prevent a printing error due to an input error of the user.

Japanese Patent Publication No. 1-47725 (first and third pages, FIG. 2) JP-A-6-32338 (pages 2, 3 and 5; FIG. 1) JP-A-7-260956 (pages 3 and 4, FIG. 1) Japanese Patent Laying-Open No. 2003-341151 (pages 3 and 5 and FIG. 5)

  By the way, the effective days of the product such as the expiration date and the expiry date may be slightly different between the case of freezing and the case of carrying at normal temperature. Furthermore, it may differ depending on the storage method in the retail store. In addition, when several kinds of confectionery are packaged and sold, it is necessary to display the earliest expiration date among them on the outer box.

  However, according to the configuration in which the expiration date is calculated by the calculation means as in Patent Documents 1 to 3, it is difficult to set a flexible expiration date according to the above-described transport temperature, storage temperature, and boxing content. In addition, in order to be able to respond to each case, a complicated input operation is required, and the operability of the label printer may be reduced.

  In addition, as in Patent Document 4, it is difficult to correct the date so as to prevent tampering, because the input change according to the case classification as described above is hindered, so that the operability is poor for the operator. There is a problem that the work efficiency becomes worse.

  Therefore, the present invention was created in view of the above-described problems, and provides a label printer that can prevent erroneous display of an effective date due to a display label without deteriorating operability for an operator. Objective.

The label printer according to the present invention is a label printer that produces a display label that is attached to a predetermined article and displays an article name and an effective date, and the minimum value and the maximum value of the effective days of the article are set to the minimum number of days. And storage means for storing each article as the maximum number of days, an article name to which the display label is pasted, an input means for inputting the starting date and the effective date of the effective date of the article, and input from the input means corresponding to the article name, the minimum number of days and maximum number of days, and a control means for reading from the storage means, in response to a control command from the control unit, and a label making means for making a label for an article, the control means input It is determined whether or not the effective date entered is within the range from the date obtained by adding the minimum number of days read out from the input calculation date to the date obtained by adding the maximum number of days read out from the calculation date. , The effective date is If not within the range, is characterized in that no manufacturing a display label.

According to the label printer of the present invention, the control unit reads the minimum number of days and the maximum number of days corresponding to the input article name from the storage unit, and the input effective date is read out on the input start date . Judge whether it is within the range from the date added with the minimum number of days to the date added with the maximum number of days read out on the starting date , and if the effective date is not within the range, create a display label Not to be done. Accordingly, it is possible to detect in advance an erroneous input of the input effective date.

According to the label printer of the present invention, the label printer includes control means for reading out the minimum days and the maximum days corresponding to the input article name from the storage means for storing the minimum days and the maximum days as the effective days of the articles for each article. control means, effective date entered is in the range from the date obtained by adding the minimum number of days read the value date entered to the date obtained by adding the maximum number of days that has been read to the person the value date If the effective date is not within the range, the display label is not prepared .

With this configuration, it is possible to detect an erroneous input of the valid date in advance. Accordingly, for example, erroneous display of the effective date of the product such as the expiration date or the expiration date can be prevented, so that the reliability of the article to which the display label is attached can be maintained.

  Next, a label printer according to the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a configuration example of a label printer 100 as a first embodiment according to the present invention. A label printer 100 shown in FIG. 1 is a label that is attached to a predetermined article (product) and displays a product name, an effective date, and the like.

  The label printer 100 prints predetermined information on a label sheet 1 attached to a predetermined site, and produces a display label of, for example, a boxed candy.

  Here, the label sheet 1 attached to the label printer 100 has a white seal-like thermal paper label 3 continuously pasted on a sheet 2 constituting an example of release paper, and has a space in the core. It is rolled up.

  The label printer 100 prints predetermined information on the label 3 attached to the attached label sheet 1 to produce a display label. In addition, the label printer 100 of this example can take out the label 3 from the sheet 2 in addition to taking out the label 3 while being attached to the sheet 2.

  The label printer 100 is roughly configured to include a main body 50 and a lid 60. The main body 50 and the lid 60 are connected at one end so as to be openable and closable. For example, the main body 50 and the lid 60 are opened when the label sheet 1 is mounted, and are closed when the display label is manufactured. In the following description, the main body portion 50 and the lid portion 60 are connected to each other as a rear portion and the other as a front portion.

  The main body 50 includes the core shaft 10, the peeling part 30, the support part 51, the sheet base 52, the guide 53, the roller 54, the label sensor 55, and the control part 56. The core shaft 10 is a roll core for attaching a label sheet, and is inserted into the core part of the label sheet 1. Here, the core shaft 10 is attached with the label sheet 1 at the central portion in the longitudinal direction, and both ends thereof are supported by the support portions 51 of the main body portion 50.

  Here, the support portions 51 are provided on the left and right of the rear portion of the main body portion 50, and support the core shaft 10 rotatably. In this example, the support portion 51 includes support recesses 51a having a substantially semicircular cross-sectional shape at the inner portions facing each other, and both ends of the core shaft 10 are fitted in the support recesses 51a. A seat base 52 is provided on the front side of the support portion 51 with a predetermined inclination.

  The sheet base 52 constitutes an example of a conveyance unit, and constitutes a conveyance path for conveying the label sheet 1 fed from the core shaft 10. The sheet base 52 has a smooth surface and moves the label sheet 1 on the upper surface. Here, guides 53 are provided on the left and right sides on the front side of the seat base 52.

  The guide 53 lightly clamps the label sheet 1 from the width direction and guides the label 3 to an appropriate printing position. In this example, the guide 53 has a simple mechanism that approaches and separates from each other symmetrically. A label sensor 55 is installed on the sheet base 52 located inside the guide 53 here.

  The label sensor 55 senses the position information of the label 3 of the label sheet 1 and outputs a signal to the control unit 56. The label sensor 55 detects the tip 3a of the label 3 passing through the upper surface by detecting a difference in light transmittance, and outputs a rising signal to the controller 56 here. The controller 56 detects the rising signal, sends the label 3 to the printing position, and executes the printing operation. A roller 54 is provided on the front side of the label sensor 55.

  The roller 54 constitutes an example of a conveying unit together with the sheet base 52, and is made of a material having a large frictional force such as rubber, and feeds the label sheet 1 in the front direction. The roller 54 rotates according to a command from the internal control unit 56 to move the label sheet 1 by a predetermined distance. Further, the label sheet 1 is printed with predetermined information on the roller 54 by the thermal head 61 of the lid 60. The printed label sheet 1 is sent to the outside through the peeling unit 30.

  The peeling unit 30 includes a peeling cover 31 and a delivery path 33 on the back surface of the peeling cover 31, separates the label 3 from the sheet 2 fed out from the core shaft 10, and sends each of the labels 3 to the outside. The delivery path 33 has an entry portion 33a between the roller 54 and the peeling cover 31, and the sheet 2 is inserted from the entry portion 33a. Since the delivery path 33 is bent at a substantially right angle from the conveyance path of the label sheet 1 by the sheet base 52, only the relatively thin and soft sheet 2 is delivered. Thereby, the label 3 comes to peel from the sheet | seat 2 in the entrance part 33a. The peeled label 3 is sent out from the upper surface of the peeling cover 31.

  Further, when the sheet 2 is not inserted into the core insertion portion 33 a and disposed on the upper surface of the peeling cover 31, the label 3 on which information is printed is fed out to the outside without being separated from the sheet 2.

  A control unit 56 provided at a predetermined site inside the main body unit 50 controls various operations of the label printer 100. In this way, the main body 50 is configured.

  The lid 60 connected to the main body 50 so as to be openable / closable includes a thermal head 61, a label sensor 62, and a roller 65 on the back surface facing the main body 50, and the input key 21 and the display 22 on the front surface. (See FIG. 2).

  The thermal head 61 is installed at a position that is above the roller 54 when the lid 60 is closed. The thermal head 61 generates heat to the printing portion in accordance with a command from the control unit 56, prints predetermined information on the label 3 on the roller 54, and produces a display label for the article.

A label sensor 62 is provided at a position on the label sensor 55 when the lid 60 is closed. The label sensor 62 senses the tip 3 a together with the label sensor 55. Furthermore, a roller 65 is provided at a position on the sheet base 52 when the lid 60 is closed. The roller 65 constitutes an example of a conveying unit together with the sheet base 52 and the roller 54, and rotates according to a command from the control unit 56 to convey the label sheet 1 on the sheet base 52 toward the front side.
On the other hand, the input key unit 21, which is an input means provided on the front side of the lid 60, is provided with numeric input keys, character input keys, and the like, and is operated to input information such as product names and effective dates. Similarly to the input key unit 21, the display unit 22 arranged on the front surface side of the lid unit 60 displays information input from the input key unit 21 or information printed by the label printer 100 in response to a command from the control unit 56. Etc. are displayed. The label printer 100 is configured as described above. Hereinafter, the control unit 56 will be described.

  FIG. 2 is a diagram illustrating a configuration example of the control unit 56. 2 includes a CPU 71, a RAM 72, a ROM 73, and a nonvolatile memory 74. The CPU 71 constitutes an example of a control unit, and executes a predetermined print process by the label printer 100 in accordance with an execution command input from the input key unit 21.

  When the execution instruction is input, the CPU 71 reads out a necessary program from programs stored in the ROM 73 in advance and develops it in the RAM 72 to execute a printing operation and a conveying operation by the label printer 100. In addition, in the nonvolatile memory 74 which is an example of a storage unit, data including a database D11 described later is stored in a rewritable manner. The CPU 71 executes control processing while reading data from the nonvolatile memory 74 or the like as necessary.

  The control unit 56 is connected to the input key unit 21, the display unit 22, the print unit 23, and the like. The print unit 23 constitutes an example of a label producing unit, and includes a thermal head 61, rollers 54 and 65, and the like. The printing unit 23 prints predetermined information on the label 3 while conveying the label sheet 1 to produce a display label to be attached to the product.

  At the time of producing the display label, the name of the product, the date from which the product is effective, the effective date to be displayed, and the like are input from the input key unit 21. Here, the starting date of the product is the date of manufacture or date of processing of the product, and the effective date of the product is the date indicating the expiration date or the expiration date. Also, the effective date here is the date that you want to display on the display label entered by the operator, and is usually set to the date that is the base date (standard number of days) set for each product plus the starting date. The

  By the way, the effective days of products that can be displayed on the display label are set within a predetermined allowable range. The minimum value and the maximum value of the effective days for each product are stored in the nonvolatile memory 74 as the minimum days and the maximum days. In this example, they are stored as period 1 and period 2 in the database D11 as shown in FIG.

  At the time of producing the display label, the CPU 71 reads the minimum number of days and the maximum number of days corresponding to the input product name from the database D11, and adds the minimum number of days of the product read from the database D11 to the input calculation date. The printing unit 23 is controlled based on the result of comparing the date and the date obtained by adding the maximum number of days read out on the starting date with the input effective date.

  The CPU 71 is connected to a connector 75 that is an example of a connection unit. The connector 75 is provided so as to be connectable to an external memory 76 that is an external storage means for storing the database D11. The CPU 71 can also read the database D <b> 11 from the external memory 76 connected to the connector 75 and store it in the nonvolatile memory 74.

  The external memory 76 includes a hard disk of a personal computer, a CF memory, a stick memory, and the like, and the connector 75 includes a connector for a USB terminal, a CF memory, a stick memory, and the like.

  The database D11 is usually created by a personal computer or the like and stored in the external memory 76. If the database D11 is collectively managed by a predetermined sales headquarters so that it can be sent to a merchandise store via e-mail or the like, it becomes possible to easily cope with the change of seasons and the addition of new products.

  FIG. 3 is a table showing a configuration example of the database D11. In the database D11 of this example shown in FIG. 3, the product number and the corresponding product name, period 1, period 2, raw material name and the like are stored. In the database D11, for example, information relating to 800 to 1000 products is stored.

  Here, the product number indicates a product identification number. One product number is assigned to one product. The product name indicates a name that is valid for the general society of the product.

  The period 1 indicates the minimum value of the effective days that can be displayed on the display label, and is set to a number of 0 or more. For example, if a product whose maximum number of days from the date of manufacture to the expiration date is usually about 30 days, and the date one day after the date of manufacture is displayed as the expiration date, the consumer can feel anxiety and distrust There is sex. For these reasons, the minimum number of effective days is set.

  Period 2 shows the maximum number of valid days that can be displayed on the display label. Usually, the period 2 indicates the number of days from the date of manufacture of the product to the expiration date. In addition to this, the database D11 stores raw material names, manufacturer information (not shown), and the like. A display label is produced based on such information in the database D11.

  4A to 4C are diagrams illustrating an example of input control by the control unit 56. FIG. 4A shows items input from the input key unit 21 when the display label is manufactured. When the product number, the product name, and the date of manufacture shown in FIG. 4A are input, the CPU 71 reads period 1 and period 2 as a date range corresponding to the input product name or product number from the database D11. .

  The CPU 71 adds the read period 1 and period 2 to the input manufacturing date (H19.9.1), respectively, and the earliest expiration date that can be displayed on the display label as shown in FIG. 4B. Calculate the date and the latest date. The earliest date is the earliest date that can be expressed as the expiration date, and the latest date is the earliest date that can be expressed as the expiration date.

  Thereafter, when the expiration date as shown in FIG. 4C is input by the operator from the input key unit 21, the CPU 71 compares the input expiration date with the calculated earliest date and latest date, and the result The print unit 23 is controlled based on the above.

  The CPU 71 in this example creates a display label as a print OK when the input expiration date is later than the earliest date and earlier than the latest date as in the date input 1, and as in the date input 2, When the input expiration date is not within the range between the earliest date and the latest date, control is performed so as not to produce a display label as printing NG.

  FIG. 5 is a flowchart illustrating an example of print control by the control unit 56. For example, when producing a display label for a cake using the label printer 100, first, a product number, a product name, and a manufacturing date of the cake are prepared. Under these processing conditions, the CPU 71 monitors whether or not a layout has been selected in step A1 of the flowchart shown in FIG. The layout is an array format of display labels, and a plurality of layouts are stored in the ROM 73, the non-volatile memory 74, or the like according to the type of display information of the product and the size of the product.

  If a layout is selected, it will progress to step A2 and input operation of a merchandise name and a merchandise number will be performed. At this time, the CPU 71 controls the display unit 22 to display a prompt for input of a product name and a product number. The operator operates the input key unit 21 to input the product name and product number of the display label to be produced. When the product number is input, the control unit 56 may read the product name corresponding to the product number from the database D11 and display it on the display unit 22.

  When the product number is input, the process proceeds to step A3, where the manufacturing date (or processing date) is input. At this time, the CPU 71 controls the display unit 22 to display screen information that prompts the manufacture date.

  Here, the label printer 100 may be provided with a time measuring means, and the date and time of input may be displayed on the display unit 22. In this case, the manufacturing date may be input only when the displayed date is different from the manufacturing date.

  When the date of manufacture is input, the CPU 71 proceeds to step A4 and reads the period 1 and the period 2 from the nonvolatile memory 74. Here, the CPU 71 reads out the period 1 and the period 2 corresponding to the product number input in step A2 from the database D11.

  When the period 1 and the period 2 are read out, the process proceeds to step A5, and the CPU 71 adds the period 1 and the period 2 to the date of manufacture input in step A3, and sets the earliest date and latest date of the best before date. Set.

  In step A6, the CPU 71 inputs the expiration date by the operator. At this time, the CPU 71 displays a predetermined display on the display unit 22 and prompts the input of the expiration date. At this time, the earliest date and the latest date set in step A5 may be displayed.

  In step A7, the CPU 71 compares the input expiration date with the earliest date and latest date calculated based on the information read from the database D11, and the input expiration date is from the earliest date to the latest date. If it is not within the range, the process returns to step A6 to prompt the user to re-enter the expiration date. If it is within the date range, the process proceeds to step A8.

  In step A8, the CPU 71 controls the printing unit 23 to execute printing on the label 3 to produce a predetermined display label. In this way, the print control of the control unit 56 is performed.

  As described above, according to the label printer 100 according to the first embodiment of the present invention, the minimum number of days (period 1) and the maximum number of days (period 2) of the effective days of the articles are input from the database D11. A CPU 71 that reads the period 1 and the period 2 corresponding to the article name, and the CPU 71 adds the read period 1 to the input manufacturing date (or processing date), and the manufacturing A display label is produced based on the result of comparing the date obtained by adding the period 2 read out on the year, month, and day with the input expiration date (or expiration date).

  With such control, when producing a display label, it is possible to determine whether or not the input expiration date is within the range of the earliest date and the latest date that can be displayed. Input can be detected in advance. Thereby, since the misdisplay of the expiration date can be prevented, the reliability of the article to which the display label is attached can be maintained.

Further, since the expiration date can be freely set within the range from the earliest date to the latest date, the effective date of the product can be flexibly set according to the transport method and the storage method. For example, when carrying at room temperature, the shelf life of the product can be set shorter than usual so that the safety of the product can be more reliably maintained.

  In this case as well, it is possible to prevent the expiration date from being set to an early date that harms the consumer's credit, or from being set to a later date after the original expiration date has passed. As a result, erroneous display of the expiration date can be prevented and the reliability of the product can be maintained.

  6A to 6C are diagrams showing an example of input control as a second embodiment executed by the control unit 56. FIG. In this example, the label printer 100 according to the first embodiment is used to produce a display label to be affixed to a plurality of products, here a cake and a confectionery box of Japanese confectionery. In this example, the same names and reference numerals as those in the first embodiment have the same function and the same structure, so that the description thereof is omitted.

  FIG. 6A shows items input from the input key unit 21 when the display label is manufactured. When the product number, product name, and date of manufacture related to the cake and Japanese confectionery shown in FIG. 6A are input, the CPU 71 reads the period 1 and the period 2 of the cake and the Japanese confectionery from the database D11.

  The CPU 71 adds the read cake period 1 and period 2 to the date of manufacture of the input cake and displays the earliest date that can be displayed as the cake expiration date as shown in the upper part of FIG. Calculate the late date. Similarly, the period 1 and period 2 of the Japanese confectionery are added to the date of manufacture of the input Japanese confectionery, and the earliest date and the latest date that can be displayed as the expiration date of the Japanese confectionery as shown in the lower part of FIG. 6B. And calculate.

  The CPU 71 compares the earliest date between the cake and the Japanese confectionery and sets the latest earliest date as the joint earliest date, compares the latest date between the cake and the Japanese confectionery, and compares the earliest latest date with the latest latest date. Set as date.

  In this example, H19.9.4, which is the earliest date of Japanese confectionery, is set as the joint earliest date, and H19.911, which is the latest date of cake, is set as the joint latest date.

  Thereafter, when the expiration date as shown in FIG. 6C is input from the input key unit 21 by the operator, the CPU 71 compares the input expiration date with the joint earliest date and the joint latest date, and the result The thermal head 61 is controlled based on the above.

  The CPU 71 in this example, like the date input 1, when the input expiration date is later than the joint earliest date (H19.9.4) and earlier than the joint latest date (H19.9.11), A display label is produced as printing OK, and when the inputted expiration date is not within the range from the joint earliest date to the joint latest date as in date input 2, the display label is not produced as printing NG. The printing unit 23 is controlled.

  FIG. 7 is a flowchart illustrating an example of print control for a boxed product. When producing a display label for an assortment box of cake and Japanese confectionery using the label printer 100, first, the product number, product name, and date of manufacture of the cake and Japanese confectionery are prepared. Under these processing conditions, the CPU 71 monitors whether or not the display label layout has been selected in step B1 of the flowchart shown in FIG.

  When the layout is selected, the process proceeds to step B2, and an operation for inputting a plurality of product names and product numbers to be boxed is performed. At this time, the CPU 71 controls the display unit 22 to display a prompt for input of a product name and a product number.

  The operator operates the input key unit 21 to input a product name and product number to be packed, for example, cake (product number: 0011) and Japanese confectionery (product number: 0112). Further, when the product numbers 0011 and 0112 are input, cakes and Japanese sweets may be displayed on the display unit 22 as product names corresponding to the product numbers.

  When the product number is input, the process proceeds to step B3, and an operation for inputting the manufacturing date (or processing date) of each product, here, cake and Japanese confectionery is performed. At this time, the CPU 71 controls the display unit 22 to display screen information that prompts input of the date of manufacture of each product.

  When the manufacturing date is input, the CPU 71 proceeds to step B4, and reads the period 1 and the period 2 corresponding to the product number input in step A2 from the database D11 stored in the nonvolatile memory 74.

  When the period 1 and period 2 of the cake and Japanese confectionery are read out, the CPU 71 proceeds to step B5, and the date of manufacture of the cake input at step B4 and the period 1 and period of the cake read out at step B4 2 is added to set the earliest date and latest date of the cake expiration date. Similarly, period 1 and period 2 of Japanese confectionery are added to the date of manufacture of the Japanese confectionery to set the earliest date and latest date of the shelf life of the Japanese confectionery.

  In step B6, the CPU 71 sets the joint earliest date and the joint latest date of the products to be boxed. At this time, the CPU 71 compares the earliest date of the cake with the earliest date of the Japanese confectionery, and sets the later date as the joint earliest date. Further, the latest date of the cake is compared with the latest date of the Japanese confectionery, and the earlier date is set as the joint latest date.

  When the process proceeds to step B7, one expiration date input operation is performed. At this time, the CPU 71 displays a predetermined display on the display unit 22 and prompts the operator to input the expiration date to be displayed on the display label.

  In step B8, it is compared whether or not the input expiration date is within the range of the joint earliest date and the joint latest date. At this time, the CPU 71 compares the input expiration date with the set joint earliest date and the joint latest date, and when the input expiration date is not within the range of the joint earliest date and the joint latest date. Returning to step B7, the user is prompted to re-enter the expiration date. If the expiration date is within the range, the process proceeds to step B9.

  In step B9, the CPU 71 controls the printing unit 23 to execute printing on the label 3. In this manner, print control is performed by the control unit 56, and display label production is performed by the label printer 100.

  As described above, according to the label printer 100 according to the second embodiment of the present invention, the period 1 and the period 2 corresponding to each of a plurality of input products are read out, and the manufacturing for each input product is performed. The combined earliest date and the combined latest date are set from the date obtained by adding the period 1 and the period 2 for each product.

  With this control, when producing a display label for a packaged product, it is possible to determine whether or not the one expiration date entered is set between the earliest date and the latest date of all the products, It is possible to prevent erroneous display of the expiration date.

In addition, since the expiration date can be freely set within the range from the joint earliest date to the joint latest date, flexible operability can be maintained.

  The present invention is extremely suitable when applied to the production of display labels for foodstuffs such as assorted confectionery.
