Abstract: An outgoing path port and a returning path port of a circulation path are at a position that is lower than a printing head. The outgoing path port and a discharge port of a discharge path are at a position that is lower than the returning path port. When ink droplets are ejected from the printing head, ink is pumped from a main tank to a sub tank using a supply pump, and ink is pumped from the outgoing path port to the printing head using a circulation pump with an opening and closing valve open and an opening and closing valve closed. In a case where discharge of ink in the sub tank and a circulation path is instructed before replacing of an ink unit, ink is pumped from the outgoing path port to a junction side using the circulation pump with both of the valves open.

Abstract: A method and optical component prevent external light reflection and increase light extraction efficiency. In one example embodiment, an optical component is provided on a light extraction side of a light-emitting panel. After a shielding film shaped like a lattice or a mesh is formed on a transparent substrate, a resist film is formed, the resist film is irradiated with ultraviolet light UV from the back side of the substrate by using the shielding film as a mask, and development is carried out, so that an optical functional element is formed. The planar shape of the undersurface of the optical functional element is the same as the planar shape of the lattice or the mesh of the shielding film, and a positioning error between the optical functional element and the shielding film becomes extremely small.
