液体喷射头以及液体喷射装置
摘要：
本发明提供能够获得稳定的吐出性能的液体喷射头及液体喷射装置。其特征在于，具有：吐出通道，其沿通道延伸方向，并且填充油墨；虚设通道(62)，其沿通道延伸方向延伸，并且不填充油墨；喷嘴板(51)，其层叠于促动器板(52)，且具有喷嘴孔，该喷嘴孔在吐出通道的通道延伸方向的中央部分处连通于吐出通道内，在促动器板(52)，第一通道列(63)及第二通道列(64)在通道延伸方向上隔开间隔地形成，第一通道列(63)及第二通道列(64)是吐出通道及虚设通道(62)分别在X方向上交替地并列设置而构成的，吐出通道及虚设通道(62)分别相对于通过通道延伸方向的中心与通道延伸方向正交的对称面面对称地形成。
摘要（英）：

A liquid jet head includes ejection channels which extend in a channel extending direction and are filled with ink, dummy channels which extend in the channel extending direction and are not filled with ink, and a nozzle plate which is laminated on an actuator plate and includes nozzle holes each communicating with the corresponding ejection channel at a central part in the channel extending direction of the ejection channel. The actuator plate includes a first channel row and a second channel row each of which includes the ejection channels and the dummy channels alternately arranged side by side in the X direction, the first and second channel rows being spaced apart in the channel extending direction. The ejection channel and the dummy channel are each symmetric with respect to a plane that passes through the center in the channel extending direction and perpendicular to the channel extending direction.
