Title:
LIQUID JETTING HEAD AND RECORDING APPARATUS USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/034892
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a liquid jetting head wherein a shift of the liquid jetting direction from the direction orthogonal to the jetting port plane is small, and a recording apparatus using the liquid jetting head.
[Solution] A liquid jetting head (2) of the present invention is provided with a jetting port (8), a jetting port plane (4-1) having the jetting port (8) formed therein, a pressurization chamber (10), and a flow channel (13) that connects the jetting port (8) and the pressurization chamber (10) to each other. The flow channel (13) includes a nozzle section (13a) and a partial flow channel (13b), and in the partial flow channel (13b), when an average diameter is represented by W [μm], a center of gravity of area on the nozzle section (13a) side is represented by C1, a center of gravity of area at a position 2W [μm] from the nozzle section (13a) side is represented by C2, a center of gravity of area on the pressurization chamber (10) side is represented by C3, and an intersection between a straight line formed by connecting C1 and C3, and a plane at a position 2W [μm] from the nozzle section (13a) side, said plane being parallel to the jetting port plane, is represented by Cm, the distance (Dm) in the planar direction between Cm and C1 is larger than 0.1W [μm], and the distance (D2) in the planar direction between C2 and C1 is equal to or less than 0.1W [μm].
