Patent ID: 8448635

Claim:
A discharge head to be used for a droplet discharging device for discharging liquid from discharge ports by exerting pressure, comprising: a first orifice plate having first discharge ports of a first discharge port diameter; a second orifice plate arranged parallel to and at a position separated from said first orifice plate in the liquid discharge direction, said second orifice plate having second discharge ports of a second discharge port diameter; and a plate-securing member located between said first orifice plate and said second orifice plate and connected to both said orifice plates, wherein said plate-securing member has a hollow space extending in the liquid discharge direction and connecting said first discharge ports and said second discharge ports such that a cross-section of said hollow space taken along a plane running parallel to said orifice plates becomes smaller as one approaches said first orifice plate or said second orifice plate, and wherein said second discharge port diameter is smaller than said first discharge port diameter.
