  • Patent number: 8585194
    Abstract: An ink cartridge has a label portion on a wall surface of one periphery of a case forming an ink accommodating unit. The label unit has an optical functional layer that allows a predetermined wavelength of light to pass, an optical dispersion layer that includes hollow bodies, and an optical absorptive layer that absorbs the first wavelength of light, which are laminated in this order, and the optical absorptive layer is a surface side of the case. When the optical reflective layer is heated from a heating unit directed to the label portion at a temperature of damaging the hollow bodies, the dispersion of the light is suppressed by the damage to the hollow bodies, and the transmittance of the wavelength of light is irreversibly raised.
