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 a lamination structure in which a plurality of layers with different properties and states are laminated, and includes an optical functional layer that allows light (first wavelength of light) with a predetermined wavelength to pass and an optical reflective layer that reflects the first wavelength of light, and the optical reflective layer is a surface side of the case. When the optical reflective layer is heated from a thermal head of a heating unit directed to the label portion, the optical reflective layer irreversibly raises absorptivity of the first wavelength of light with respect to a received range.

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.

Abstract: A printing device that facilitates processes requested in relation to a print recording medium reservoir. When a contact detecting switch 25 is turned on by a proximate ink cartridge CA, a personal computer PC identifies the proximate ink cartridge CA. The personal computer PC, in the event that the duration of sustained proximity of the proximate ink cartridge CA is longer than a predetermined time interval Tref, reads out the remaining quantity of ink from the memory device module M of the proximate ink cartridge CA and displays this on an external display device 40. In the event that the duration of sustained proximity is shorter than predetermined time interval Tref, the personal computer PC drives the carriage 101 so as to move an ink cartridge CA installed on carriage 101 corresponding to the proximate ink cartridge CA to a replacement opening 14.
