Document Type and Number:
WIPO Patent Application WO/2010/103937
Kind Code:
A1
Abstract:
Provided are a liquid jetting head having improved performance of recovering an excessive ink, a liquid jetting recording device, and a method for filling the liquid jetting head with a liquid. The liquid jetting head is provided with: a jetting body (23) having a jetting port row (31c) composed of a plurality of jetting ports (31a); a plurality of pressure generating chambers (26) connected to the jetting ports; a liquid supply system which supplies the pressure generating chambers with the liquid; an actuator (21) disposed adjacent to the pressure generating chambers; and a jetting body guard (24), which is disposed by being spaced part from the surface (32f) of the jetting body and has a top plate section (24a) on which a slit (24c) that faces the jetting port row is formed. In the liquid jetting head, the jetting port row is disposed in the perpendicular direction, the inside of the pressure generating chambers is pressurized by driving the actuator, and the liquid in the pressure generating chambers is jetted in the horizontal direction from the jetting ports. Guide sections (40) are provided on the side of the jetting port row such that the liquid overflowed from the jetting ports is guided downward in the gravity direction toward the further side from the jetting ports.
