Patent attributes
A droplet discharging head includes: a nozzle portion that discharges a liquid material; a liquid chamber that is in communication with the nozzle portion and supplies the liquid material to the nozzle portion in receiving a pressure from outside; and a reservoir that is in communication with a plurality of the liquid chamber through a plurality of ink supply passages and supplies the liquid material fed from outside via a material inlet to the plurality of liquid chambers. In the droplet discharging head, assuming that: a direction running from the material inlet toward the liquid chamber is a first direction; a direction perpendicular to the first direction is a second direction; a straight line passing through the material inlet in the first direction is a first reference line; and a straight line passing through the material inlet in the second direction is a second reference line, the longer a distance from the second reference line is for a liquid chamber, the shorter a distance from the first reference line is for the liquid chamber.
