Problems solved by technology

However, there is a problem that, for example, if the product label is wrinkled or the barcode is partially stained, the barcode cannot be read by the reading unit
[0003] However, since it cannot be said that reading units capable of reading digital watermarks are widespread enough, the inventors believe that there is a need to print commodity labels with barcodes attached together with digital watermarks.
However, if the digital watermark is superimposed on the barcode, the contrast between the bar and the space of the barcode cannot be formed, and a new problem arises in that the reading accuracy of the barcode by the reading unit is reduced.

Deformed example 1

[0072] The print data generated by the control unit 93 is not limited to the print data generated by the above-described processing, and may be, for example, print data generated by the processing described below. Below, refer to 6A to 6D A method of generating print data according to this modification will be described in more detail.

[0073] The control unit 93 generates a format that defines which product information is arranged in which area of ​​one product label L. Figure 6A As shown, it is assumed that the commodity information other than the digital watermark A5 is printed on the commodity label L as the fifth data (fifth processing) of the arrangement position of each commodity information. The fifth data of the present embodiment is defined as the barcode A3 being arranged in the first predetermined area (predetermined area) PA1.

[0074] Next, the control unit 93 generates a definition Figure 6B As shown, the dividing line L1 dividing one product label L into...

Deformed example 2

[0081] refer to 8A to 8E A method of generating print data according to Modification 2 will be described in detail.

[0082] The control unit 93 generates a definition in Figure 8A The first data of the content of the digital watermark A5 is arranged in all areas of one product label L as shown. Next, the control unit 93 generates a format that defines which product information is arranged in which area of ​​one product label L. Figure 8B As shown, it is assumed that the product information other than the digital watermark A5 is printed on the product label L as the second data of the arrangement position of each product information. The second data in the present embodiment is defined as the barcode A3 being arranged in the first predetermined area PA1. It should be noted that the second data may not necessarily be generated in a state where the barcode A3 is actually arranged in the first predetermined area PA1.

[0083] Next, the control unit 93 generates a definitio...

Deformed example 3

[0086] The weighing and packaging pricing device 1 according to the above-described embodiment and modification 2 has been described as an example in which a blank area is formed around the barcode A3 and a digital watermark A5 is arranged around the blank area, but the present invention is not limited to this. For example, the digital watermark A5 may be arranged in the above-mentioned blank area.

Abstract

The invention relates to a label issuing device and a label reading device. The label dispensing device includes: a storage unit that stores a plurality of items of product information relating to a product; and a print control unit that generates print data in which a barcode obtained by encoding at least one item of product information stored in the storage unit and an electronic watermark into which at least one item of product information among the item information encoded as the barcode is embedded are disposed on one item label. The bar code and the electronic watermark are mutually configured at different positions in a commodity label; and a label issuing unit for issuing a product label in which the barcode and the electronic watermark are mutually displayed at different positions by printing information based on the print data on the label.

Description

technical field [0001] One aspect of the present invention relates to a label dispensing device and a label reading device. Background technique [0002] Conventionally, a product label printed with a barcode in which product information is encoded has been affixed to a product. Then, by reading the barcode with the reading unit, the calculation of the commodity is performed at a cash register or the like, or the inventory management is performed at a warehouse or the like. However, there is a problem that the barcode cannot be read by the reading unit if, for example, the product label is wrinkled or the barcode is partially soiled. Therefore, it has been proposed to print on the product label an electronic watermark that can be printed on the entire product label and has excellent reading accuracy by a reading unit such as a camera (refer to Patent Document 1: Japanese Patent Laid-Open No. 2008-252482). It is considered that the above-mentioned problems can be solved by ...
