no. 1 Embodiment approach
[0071] figure 1 It is a schematic diagram of the information pattern carrier and the reading device for carrying out the optical reading method of this embodiment. The reading device 1 reads information on the information recording card 10A, and has a schematic configuration including a light emitting diode 15 and an optical reading mechanism 2 .
[0072] The information recording card 10A includes an information recording medium 11 and an information pattern carrier 11A on the information recording medium 11 . The information pattern carrier 11A has a printed information pattern 12 such as a visible barcode or a QR code, and a mask printed body 13 that makes the information pattern 12 overlap by printing the information pattern 12 after printing the information pattern 12. The information pattern 12 becomes invisible. The information recording card 10A is a card-shaped object on which information is recorded, and is suitable for, for example, cash cards, various prepaid car...
no. 2 Embodiment approach
[0097] Figure 4 It is a schematic diagram of a reading device for implementing the optical reading method of the second embodiment. The information recording card 10B of this embodiment has an information pattern carrier 11B, and the information pattern carrier 11B has an information recording medium (or managed object) 11, a base printing layer 14 that is printed on the information recording medium 11 but does not form an information pattern, and printed on the information pattern carrier 11B. An information pattern 12 such as a barcode or a QR code on the information recording medium 11 . In addition, the same code|symbol is attached|subjected to the part which overlaps with 1st Embodiment, and description is abbreviate|omitted.
[0098] In this embodiment, the information pattern 12 is made invisible by setting the color of the information pattern 12 to be the same color as the color of the undercolored printed layer 14 obtained by underprinting the information pattern 12...
no. 3 Embodiment approach
[0102] Figure 5 It is a schematic diagram of a reading device for implementing the optical reading method of the third embodiment. In the reading device 1A of the present embodiment, the cooling mechanism 3 for thermally shrinking the semiconductor quantum dots is provided by cooling the semiconductor quantum dots. In addition, the same code|symbol is attached|subjected to the part which overlaps with 1st Embodiment, and description is abbreviate|omitted.
[0103] The cooling mechanism 3 is a mechanism for cooling the information pattern 12 and further cooling the semiconductor quantum dots in this embodiment. Here, the cooling mechanism 3 is an electric cooler, which is provided adjacent to or in contact with the surface of the information recording medium 11 on which the information pattern 12 is not printed, and can be cooled to a temperature of -10°C to 0°C.
[0104] As the optical sensor 16A that the optical reading mechanism 2A possesses, the figure 2 The range from...
