The label printer constitutes a product sales data processing system together with the product sales data processing device. The configuration of the product sales data processing device will be described later, but it is a device having a function of, for example, a POS (Point of Sale) cash register that reads a label and performs a customer settlement process. The label printer and the product sales data processing device are connected, for example, through a network, and information is transmitted / received via their respective communication processing units.

● Outline of the product sales data processing system (1) As shown in FIG. 1, the label printer 1 mainly includes a display unit 101, an operation unit 102, and a label discharge unit 103.
The display unit 101 is a mechanism for displaying product information and information such as a label printed for each product, and is, for example, a display. The operation unit 102 is a device for an operator to input / output information to / from the label printer 1, and receives, for example, print information to be printed on the label 100L (see FIG. 3A). Although the operation unit 102 is configured by disposing an input key below the display unit 101, it may be a touch panel display in which the display unit and the operation unit are integrated.

The label ejection unit 103 is a mechanism for ejecting the label 100L printed inside the label printer 1.

The label printer 1 may be a label printing and sticking device provided with a mechanism for further holding and moving the label and sticking the label to the product. In this case, the applicator unit that holds, moves, and affixes the label is, for example, a manipulator that can move back and forth and left and right. The label 100L is attached by pressing the product.

● Configuration of Control Device FIG. 2 is a block diagram showing a configuration example of the control device 30 of the label printer 1 and a configuration example of the control device 230 of the product sales data processing device 2 according to the embodiment.

The control device 30 of the label printer 1 includes a CPU (Central Processing Unit) 31, a flash memory 32, a RAM (Random Access Memory) 33, a communication processing unit 34, and an interface circuit 35. The control device 30 is connected to the display unit 101, the operation unit 102, the printing unit 104, and the transport unit 105 via the interface circuit 35.

The CPU 31 is a central processing unit, and controls the operation of the label printer 1 by reading and executing a program stored in the flash memory 32. The flash memory 32 is an auxiliary storage device of the CPU 31, and stores various information used by the CPU 31, including a program.

The RAM 33 is the main storage device of the CPU 31. The RAM 33 is a work area for temporarily calling and processing data, and in the work area, a dot expansion area for expanding print data into dot data, and one format data called from a label format file and stored in the RAM 33. There is a call format area, a call product area that calls and stores product data, and the like.

Further, the RAM 33 stores information to be printed on the label, that is, print information, and is backed up by a battery so as to retain the file even when the power is turned off. Further, the RAM 33 stores information about the product, for example, information on whether or not the product is a product to be sold at a discount under predetermined conditions.

The communication processing unit 34 is a device that communicates with an external device by wire or wirelessly. The communication processing unit 34 receives product information from, for example, a product sales data processing device 2 connected via a network.

The printing unit 104 prints characters and illustrations based on the printing information set by the control device 30 on the label 100L. Further, the printing unit 104 prints a filled area filled with a predetermined color on the label 100L. The filled area may be printed in the area where the characters are printed.

The printing unit 104 has an ink head. The ink head prints on the label 100L on the label paper sent out by the drive rotation of the transport unit 105. The ink head prints by ejecting ink onto label paper. The ink head is capable of ejecting a plurality of colors and can print a colorful label. The ink head prints by applying the data for one dot line supplied from the shift register as ink while moving the label paper by one dot line.

The transport unit 105 pulls out the label from the label roll housed in the label printer 1, transports the label below the ink head, and then discharges the printed label 100L from the label discharge unit 103 to the outside of the device. The transport unit 105 is, for example, a belt conveyor, and the infinite circulation zone spanned by the drive roller and the free roller rotates to convey the label 100L on the infinite circulation band. The transport unit 105 transports the label 100L in synchronization with the timing of printing by the ink head to print on the label 100L.

The label printer 1 may have a cutting portion for cutting the label drawn from the label roll to a length to be attached to the product. The cutting portion cuts the label, for example, by engaging the blades provided above and below the transport path of the label. In the label roll, the mount and the label are continuous bodies, and the label papers temporarily attached to each other are wound in a roll shape. The label 100L constitutes an adhesive surface to which an adhesive material is attached on one side and a printed surface on which the other side is printed, and the adhesive surface is detachably adhered to a mount.

Normally, in the case of a linerless label without a mount, which is made by winding a continuous body of labels, the printed surface is coated with silicon or the like so that the printed surface of the label is temporarily adhered to the adhesive surface. However, in the case of the inkjet method, the ink does not penetrate into this coating and printing cannot be performed. Therefore, by using a label roll in which the mount and the label are continuous, it is possible to print a label having a desired length by cutting the label while enabling printing by an inkjet method.
The label roll may be a roll of label paper obtained by temporarily attaching labels on a long strip-shaped mount at regular intervals. Further, a linerless label having a coating that allows ink to penetrate may be used.

Further, the label printer 1 may have a reading unit that reads the printed characters printed on the label 100L by a sensor. The reading unit generates a scanned image by performing image processing in the CPU 31, and generates scan information according to the scanned image. The scan information is corrected by the CPU 31 and then compared with the print information to determine the presence or absence of a print abnormality. The reading unit may display the error occurrence information and the error image as the comparison result on the display unit 101 when it is determined that there is a printing abnormality as the comparison result by the CPU 31. The reading unit may read the bleeding or misalignment of the ink applied by the inkjet method as a printing defect.

Although the control device 30 controls each unit together, a control device that controls the display unit 101, the operation unit 102, the printing unit 104, and the transport unit 105 may be provided.

The product sales data processing device 2 includes a CPU 231, a flash memory 232, a RAM 233, a communication processing unit 234, and an interface circuit 235. The control device 230 is connected to the display unit 201, the operation unit 202, and the reading unit 203 via the interface circuit 235. The configurations of the CPU 231, the flash memory 232, the RAM 233, the communication processing unit 234, and the interface circuit 235 may be substantially the same as those of the CPU 31, the flash memory 32, the RAM 33, the communication processing unit 34, and the interface circuit 35, respectively. A part of the function of the product sales data processing device 2 may be configured by a server or a cloud computer.

The display unit 201 is, for example, a display, and displays the name and price of the read product, information on discounts for the product, and the like. The operation unit 202 is, for example, an input key, and can select a product that cannot be read or input discount information. The display unit 201 and the operation unit 202 may be configured by one touch panel display.

The reading unit 203 is a device for reading the label 100L, and may be a handheld type device or a stationary type device for reading a product in close proximity. The reading unit 203 has, for example, a camera and can read characters, figures, and colors on the label 100L printed surface.

● Functional Blocks of Label Printer The label printer 1 constitutes each functional block of a product information acquisition unit, a print control unit, a setting unit, and a storage unit by an arithmetic unit such as a CPU 31 and a storage device such as a RAM 33 shown in FIG. It should be noted that a part or all of the functional unit may be realized by a higher-level device connected by wire or wirelessly. The host device may be, for example, a server or a cloud computer.

The product information acquisition unit is a functional unit that acquires information about a product to which a label 100L to be printed is attached, that is, product information. The product information acquisition unit may call the product information stored in the label printer 1 in advance, or may acquire the product information from the connected product sales data processing device. The product information includes at least information on the expiration date of the product, in addition to information such as the name of the product and the place where the product is manufactured. The expiration date may be referred to as an expiration date when the expiration date is short, but in this description, it is collectively referred to as a "best-by date". The best-by date is set after a different period for each product, counting from the time of manufacture.

The print control unit is an example of a printing means, and is a functional unit that controls the printing unit 104 and applies inks of various colors to the label 100L. The print control unit prints characters, illustrations, and the like indicating the product information acquired by the product information acquisition unit on the label 100L.

The setting unit is an example of the setting means, and is a functional unit that sets the color to be printed on the label by the printing unit 104. The setting unit sets whether or not to print in color in a predetermined area of the label 100L according to the expiration date of the product. More specifically, the setting unit prints the product whose expiration date is shorter than the threshold value in color. Color printing is printing in a color different from the character color, for example, printing in which a predetermined area is filled. The period from the time of manufacture to the threshold value is an example of the first period.

When the expiration date is shorter than the threshold value, the print control unit applies the color set by the setting unit to the predetermined area of the label 100L. At retail stores such as supermarkets, products with a short expiration date may be sold at a discount when the expiration date approaches. In this case, the clerk attaches a discount sticker to the product to inform the customer that the discount will be sold at the time when the discount starts.

According to the configuration in which color printing is added in advance to the label of a product with a short expiration date, which is the target of attaching the discount sticker, it becomes clear which product the clerk should attach the discount sticker to, and the affixing work. Can be advanced efficiently.

As shown in FIG. 3A, the predetermined area A100 to which the setting unit adds color printing may be an area where the expiration date is printed. According to this configuration, the color printed portion is eye-catching, so that the clerk can pay attention to the expiration date. As a result, by having the clerk confirm whether the product has a best-by date that satisfies the conditions for attaching the discount sticker, it is possible to prevent an error in attaching the discount sticker.

The setting unit may set the color to be printed on the label by the printing unit according to the expiration date of the product. For example, when the expiration date is shorter than the threshold for adding color printing, a blue filled area is printed on the label of the product shorter than the second period, and the expiration date is longer than the second period and shorter than the threshold. May print a filled area that is different from blue, for example yellow. According to this configuration, even if the discount mode differs depending on the length of the expiration date, a discount sticker may be attached at different time zones depending on the color, or a different discount sticker may be attached. It is possible to attach a discount sticker efficiently and appropriately.
The second period, which indicates the period from the time of manufacture to the best-by date, is another example of a predetermined period.

Further, the setting unit may further set the color to be printed on the label by the printing unit according to the manufacturing date and time of the product in an area different from the coloring area according to the expiration date of the product. For example, the setting unit may set a band-shaped filled area at the lower end or the upper end of the label according to the manufacturing date and time of the product. According to this configuration, since the manufacturing date and time of the product is clear at first glance, it is efficient when the store clerk puts out or displays the product.

The storage unit is an example of a storage means, and is at least a functional unit that stores product identification information and information on whether or not the product is a discount target product. FIG. 3B is an example of the label color table T101 stored in the storage unit, in which the mode of discount, the color information applied to the label 100L, and the product are linked to each other. In the example of the figure, blue is applied to the label of the product that starts discounting from 19:00, yellow is applied to the label of the product that starts discounting from 20:00, and red is applied to the label of the product that starts discounting from 21:00. Is applied. In addition, product A and product E are products whose discount starts from 19:00, product C and product D are products whose discount starts from 20:00, and product B is a product whose discount starts from 21:00. Information on when each product is a product whose discount starts is acquired by the product information acquisition unit. The setting unit refers to the label color table T101 and determines the color to be applied to the label based on the information of the discount start time. Further, the setting unit may determine the discount start time from the relationship between the best-by date of the product and the manufacturing time. The setting unit determines the color to be applied to the label based on the determined discount start time.
Further, for products that do not require discount sales, such as top-selling products, the storage unit may store the product to that effect so that the product may not be filled by color printing.

According to the configuration in which color printing is added in advance to the label of a product with a short expiration date, which is the target of attaching the discount sticker, it becomes clear which product the clerk should attach the discount sticker to, and the affixing work. Can be advanced efficiently. In addition, it is efficient because it can be easily identified when the product is disposed of, such as a product whose expiration date has expired or whose expiration date is approaching immediately before. Furthermore, even when a pre-made product is put on the sales floor during business hours, it is easy to identify which product should be put out first from among the pre-made products that are lined up in the backyard. be able to.

● Functional block of product sales data processing device The product sales data processing device 2 has a reading control unit, a discount setting storage unit, and a discount calculation unit by means of an arithmetic unit such as CPU 231 and a storage device such as RAM 233 shown in FIG. Configure a functional block. It should be noted that a part or all of the functional unit may be realized by a higher-level device connected by wire or wirelessly. The host device may be, for example, a server or a cloud computer.

The reading control unit is a functional unit that controls the reading unit 203 and reads the image information of the label. The read control unit reads the product information, that is, for example, the PLU code from the label code, and reads the price from the product master corresponding to the PLU code. Further, when the price is described in the label code together with the PLU code, the reading control unit reads the product information and the price information. Further, the read control unit identifies the color added to the label and the added area.

The discount setting storage unit is an example of the discount setting storage unit, and is a functional unit that stores the color of a predetermined area read from the label, the read time zone, and the discount mode in association with each other. FIG. 3C shows a discount table T102 stored in the discount setting storage unit. As shown in the figure, the discount setting storage unit receives a 10% discount between 19:00 and 20:00 and a 30% discount between 20:00 and 21:00 when, for example, the reading unit 203 reads blue in a predetermined area. It is remembered that the discount will be given and the price will be reduced to half after 21:00. If yellow is read, no discount is given between 19:00 and 20:00, and after 20:00, a discount is given according to the time. If red is read, the discount will be given only after 21:00.
The discount mode is not limited to discounting the product price at a predetermined discount rate, and may be a subtraction discount such that the discount price is 50 yen discount.

The discount start time of each product may be determined by the function of the discount setting storage unit from the relationship between the expiration date of the product and the manufacturing time. Further, the discount start time may be a configuration determined based on past sales such as sales on the previous day or sales on the same day in the past, instead of or in addition to the configuration fixed for each product. .. The discount setting storage unit has an AI (artificial intelligence) function for determining the discount start time, and may determine the discount start time based on the acquired information. As an element for determining the discount start time, the discount start time may be determined based on all kinds of information such as past sales, information on the store, location, customer trends at the store, and customer characteristics. Further, the discount may be performed a plurality of times stepwise at a plurality of times, and the discount setting storage unit may determine the discount mode such as each discount time, discount amount, or discount rate. These pieces of information may be appropriately transmitted to the label printer 1. In the label printer 1, the same coloring is applied to the products to be discounted in the same discount mode, and the correspondence between the coloring and the specific content of the discount mode is determined by the product sales data processing device 2. It may be a configuration.
The label printer 1 may be provided with the above-mentioned functional unit that determines the discount mode. Further, the above-mentioned functional unit that determines the discount mode may be possessed by a higher-level server such as a store server or a headquarters server, or a cloud computer. That is, the functional unit may be provided in the above-mentioned higher-level device.

The discount calculation unit is an example of the discount calculation means, and refers to the discount table T102, and the product price after the discount is obtained according to the label color of the predetermined area read by the reading control unit and the reading time. It is a functional part that calculates. The calculated product price after discount is displayed on the display unit 201 and is used for the product settlement process. According to such a configuration, since the discount is calculated together with the reading of the label, it is easy to discount the product according to the expiration date. Further, since the discount is automatically made according to the label color and the reading time, it is not necessary to attach the discount sticker as compared with the conventional mode in which the discount sticker is read and the discount is calculated.

● Outline of the product sales data processing system (2) Next, the product sales data processing system according to the second embodiment of the present invention will be described focusing on the parts different from the above-described embodiment. The same reference numerals are given to the same configurations as those in the above-described embodiment.

FIG. 4A is a diagram showing an example of the label 101L printed by the label printer 1 in the present embodiment. In the label 101L, the filled area A101 is printed in color at the lower end of the label 101L.

FIG. 4B is a diagram showing an example of the label color table T103 stored in the storage unit. In the figure, the day of the week of the expiration date and the label color are associated with each other. The day of the week is an example, and the label color has multiple days as one cycle, and the same number of color types as the number of days included in one cycle are prepared, even if the expiration date and the color are linked in a fixed cycle. good. For example, the last digit of the date and the color may be linked, or the two colors may be linked alternately on each day of the week with two weeks, that is, 14 days as one cycle. good. It is preferable that different colors are associated with each date at a cycle longer than the expiration date of the product to which the label is attached. The setting unit refers to the label color table T103 and determines the color to be applied to the label based on the day of the week to which the expiration date belongs. The best-by date day of the week is another example of the first period.
In this embodiment, the configuration of the first embodiment is applied to a product having an expiration date shorter than the threshold value, and instead of printing the fill area A101, a color fill area is set in the area where the expiration date is printed. You may print it.

According to such a configuration, in the sales floor where the products are displayed, the same color is applied to the labels of the products having the same expiration date. For this reason, in the work of attaching a discount sticker to a product whose expiration date is reached after a predetermined number of days, the product to be affixed is apparent at first glance by looking at the color of the label. That is, the discount sticker can be surely affixed to the product to be affixed without looking at the display of the expiration date in detail. In addition, it is easy for customers to select products whose expiration date is a predetermined date at the sales floor. For example, by posting the correspondence between the label color and the expiration date in a manner that can be seen by the customer, it becomes easier for the customer to understand. As a result, it also provides an opportunity for customers to select products with close expiration dates, and can reduce food loss.

FIG. 4C shows an example of the discount table T104 stored in the discount setting storage unit of the product sales data processing device in the present embodiment. In this example, the relationship between the time zone and the discount mode, which is applied when the color read by the reading control unit corresponds to the date at the time of reading, is stored. For example, when the day of the week at the time of reading and the day of the expiration date read from the label color are the same, the discount according to the discount table T104 is applied. It is stored in the discount setting storage unit that a 10% discount is given between 19:00 and 20:00, a 30% discount is given between 20:00 and 21:00, and the price is reduced to half after 21:00.

● Outline of the product sales data processing system (3) Next, the product sales data processing system according to the third embodiment of the present invention will be described focusing on the parts different from the above-described embodiment.

As shown in FIGS. 5A and 5B, the labels 102L and 103L printed by the label printer 1 in the product sales data processing system are color-printed at different positions depending on the length of the expiration date. .. When the expiration date is shorter than the predetermined time, as shown in FIG. 5A, a long and thin filled area A102 is printed on the entire width of the upper end of the label 102L. When the expiration date is longer than a predetermined time, as shown in FIG. 5B, a long and thin filled area A103 is printed on the entire width of the lower end of the label 103L. Further, the color applied to the filled areas A102 and A103 may be determined according to the day of the week of the expiration date with reference to the label color table T103. In addition, as described above, instead of the day of the week, multiple days are set as one cycle, and the same number of color types as the number of days included in one cycle are prepared, and the date and color of the expiration date are linked in a fixed cycle. May be.

According to such a configuration, it is possible to manage the necessary expiration date for both the product having a relatively long expiration date and the product having a short expiration date. Products with a short expiration date are discounted according to time, while products with a long expiration date are discounted according to the date until the expiration date, so the time and conditions for attaching the discount sticker are different. According to this configuration, the product to which the discount sticker is to be affixed is clarified, and accurate and efficient affixing work can be guaranteed.

● Outline of the product sales data processing system (4) Next, the product sales data processing system according to the fourth embodiment of the present invention will be described focusing on the parts different from the above-described embodiment.

As shown in FIGS. 6A and 6B, the label 104L printed by the label printer 1 in the product sales data processing system is color-printed at a plurality of places on the label 104L. Further, the label 104L may be printed with two or more colors other than the character color. More specifically, the filled area A104 is printed on the upper end of the label 104L over the entire width. The filled area A104 is composed of a plurality of filled areas A104a, A104b, and A104c having different colors.

FIG. 6C shows an example of the discount table T105 stored in the discount setting unit of the label printer 1 in the present embodiment. In this example, the relationship between the time zone and the discount mode, which is applied when the color read by the reading control unit corresponds to the date at the time of reading, is stored. As shown in the figure, since the product A is discounted in three stages, the filled area A104 is printed with three colors of blue, yellow, and red separately. In this case, the filled area A104 is as shown in FIG. 6A. Further, in the product B, since the discount is given in two stages of "30% discount from 20:00" and "half price from 21:00", two colors of yellow and red are printed separately in the filled area A104. Will be done. In this case, the filled area A104-2 is as shown in FIG. 6 (b). As described above, according to the configuration in which the filled areas of a plurality of colors are printed, it is possible to clarify on the label 104L even for products having different patterns of discounted time zones.

Further, in the above-described embodiment, by posting the relationship between the label color and the discount mode on the sales floor, the discount mode can be easily understood by the customer.

Further, in the label printer 1, the discount mode of the product, that is, the discount rate or the discount price of the product may be displayed in characters in the filled area A104. In the figure, the filled area A104a is printed with "10% discount from 19:00", the filled area A104b is printed with "20% discount from 20:00", and the filled area A104c is printed with "half price from 21:00". According to this aspect, since the discount mode is clarified to the customer, it is not necessary to attach the discount sticker.

A filled area A105 is printed on the lower end of the label 104L over the entire width. The color of the filled area A105 is determined by the day of the week to which the expiration date belongs, based on the label color table T103. According to this configuration, it is clear at a glance whether the expiration date of the product is the same day in the mode of discounting on the condition that the predetermined time is reached on the expiration date, and the work of attaching the discount sticker is performed. You can proceed efficiently.

The discount calculation unit of the product sales data processing device calculates the discounted product price according to the color read from the label and the position in the label on which the color is read. For example, the discount calculation unit can extract the mode of discount for each day of the week and the time zone of the expiration date by the color read from the filled area A104 and the color read from the filled area A105. Therefore, the discount calculation unit determines the degree of discount based on the day and time at the time of reading and the colors of the filled areas A104 and A105, and calculates the product price.

In the above description, the configuration in which the filled area is arranged at the upper end and the lower end of the label has been described, but the filled area may be in another area, and there is a third filled area in the other area. May be good. For example, a product or the like that is particularly desired to be reduced to half price at 16:00 may be displayed in the third filled area, or a color different from the color indicating the above-mentioned discount mode may be arranged in the filled area A104.

● Outline of the product sales data processing system (5) The product sales data processing system according to the fifth embodiment of the present invention has a configuration in which a color corresponding to the content of the product is printed on the label. That is, for example, the label printer 1 prints a filled area of blue on a product between 0 g and 100 g and a green filled area on a product between 100 g and 200 g. According to this configuration, the customer can shop efficiently because the color of the label clearly reveals the content of the product and the product with the desired content can be easily picked up. Can be done. Further, in line with this, the label printer 1 may have a configuration in which the same color is printed and issued on a price display label fixed to a display shelf of a product, that is, a shelf label or a POP.

● Summary of Embodiments The present invention relates to a label printer and a product sales data processing system.
