The inlet port section is disposed at a position lower than a position of the operation panel in a first state in which the liquid ejecting apparatus is placed on a level surface.

Abstract: A liquid holding container includes an inlet port to which ink to be supplied to a printer is introduced. The liquid holding container has a first part where at least a portion is positioned to be outside the printer and a second part where at least a portion is inserted into the printer. At least a portion of the bottom section of the first part is lower than at least a portion of the bottom section of the second part.

Abstract: A liquid container capable of containing a liquid has a flow passage that is formed in the liquid container and through which the liquid flows, and a filter 166 provided in the middle of the flow passage. The filter 166 inclines in a direction with respect to the horizontal direction.

Abstract: A liquid storage container includes a liquid storage body storing ink supplied to a printer consuming the ink. The liquids storage body includes an ink chamber which can store the ink, a filler port through which ink can be poured into the ink chamber, a lead-out port which leads out the ink stored in the ink chamber to the printer side, and a lead-out channel which connects a channel opening formed in the ink chamber and the lead-out port.

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.
